Abstract
Provided is a blood pressure measurement device that makes it possible to estimate diastolic blood pressure with high accuracy. A slice β and an inclination α included in a linear regression line formula (2) for deriving a diastolic blood pressure estimation formula (5) have a constant linear relation with each other as indicated in formula (4) and are not impacted by the measured subject, and are thus unlikely to be impacted by the individual biological features of the measured subject. As a result, it is possible to measure a diastolic blood pressure value DAPe with high accuracy. In addition, the present invention has the advantage of not requiring calibration to be carried out as in the prior art wherein blood pressure estimation is performed using the pulse wave velocity PWV.

Abstract
Provided is a blood pressure measurement device that can accurately determine a maximum blood pressure value. A maximum blood pressure value calculation unit 88 determines a maximum blood pressure value SBP of a living body 14 on the basis of the change in a cross-correlation coefficient Φ(τ) between an upstream volume pulse wave indicated by a pulse wave signal SM1 and a downstream volume pulse wave indicated by a pulse wave signal SM3, which are sequentially obtained in the process of lowering the compression pressure of a pressure cuff 12 from a value higher than the maximum blood pressure value of the living body. A change in the cross-correlation coefficient Φ(τ) between the upstream volume pulse wave and the downstream volume pulse wave indicates that blood flow in an artery that had been blocked by the pressure cuff 14 has actually started. Thus, there are no effects from feature amounts unique to living bodies, such as vascular compliance, pulse rate, pulse pressure value, and blood pressure value, which differ per measurement subject, and it is therefore possible to increase the accuracy of determination of the maximum blood pressure value SBP of a living body.

The control unit uses the shaft torque value detected by the shaft torque detection unit to generate a shaft torque correction value for the drive dynamometer DM1, receives an engine torque input value and uses the received engine torque input value to generate an engine torque correction value for the drive dynamometer DM1, and controls the drive dynamometer DM1 on the basis of a torque command value generated from the shaft torque correction value and the engine torque correction value.

Provided is a balance with a draft shield having a door that opens and closes smoothly both manually and automatically. Provided is an electronic balance (1) with a draft shield comprising: a balance body (30) having a weighing mechanism connected to a weighing pan (31); a draft shield (10) having a door (11) which can be opened and closed by sliding, the draft shield (10) that covers the weighing pan (31) to form a weighing chamber (6); and an actuator (60) for opening and closing the door (11), wherein the actuator (60) has a double-acting air cylinder (40) having two ports (44, 46) serving as air supply ports, an air pump (62) connected to the two ports (44, 46), two valves (66) interposed between the air pump (62) and the two ports (44, 467) to connect/disconnect the ports (44, 46) to/from the atmosphere, and a control device (34) that controls the two valves (66) so as to connect the two ports (44, 46) to the atmosphere when the air pump (62) is stopped. Switching between automatic opening/closing and manual opening/closing can be performed without any special mechanism, and in both cases, the door (11) of the draft shield (10) can be opened and closed smoothly.
Provided is an electronic balance that comprises a wind blocker with an automatically openable and closable door and has a high degree of freedom of design. Provided is an electronic balance (1) comprising a balance body (30) for holding a weighing mechanism coupled to a weighing tray (31) and a wind blocker (10) that has a frame (14) and a door (11) slidably provided in the frame (14) and covers the weighing tray (31) so as to form a weighing chamber (6), wherein the wind blocker (10) has, provided therein, an air cylinder (40) that is coupled to and opens and closes the door (11) and an air pump (62) for driving the air cylinder (40), and the wind blocker (10) can be freely attached to and detached from the balance body (30). Because the wind blocker (10), within which the door (11) opens and closes automatically, can be freely attached to and detached from the balance body (30), the wind blocker (10) and balance body (30) can be designed separately, and the electronic balance (1) consequently has a high degree of design freedom.
The invention relates to a balance with a draft shield having a door that opens and closes smoothly automatically. Provided is an electronic balance (1) with a draft shield comprising: a balance body (30) having a weighing mechanism connected to a weighing pan (31); a draft shield (10) that covers the weighing pan (31) to form a weighing chamber (6); a slidable door (11) that is provided at the draft shield (10) and constitutes a part of the weighing chamber (6); a holder (16) that suspends and supports the door (11) from above; a guide member (20) that is engaged with the holder (16) and slidably supports the holder (16); and an air cylinder (40) that is connected to the holder (16) and causes, through the holder (16), the door (11) to slide. Since the holder (16) that suspends and supports the door (11) is directly moved by the air cylinder (40), the door (11) can be opened and closed smoothly.

The purpose of the present invention is to provide a tire testing device. This tire testing device is a drum-type tire testing device provided with: a drum comprising, on the outer circumferential surface thereof, a transparent section and a sensor for measuring the ground contact force of a tire; an imaging device that captures an image of the ground contact surface of the tire from the inner side of the drum via the transparent section; a ground contact force measurement processing unit for measuring the ground contact force of the tire in contact with the sensor; a ground contact surface imaging processing unit that uses the imaging device to capture an image of the ground contact surface when the tire is in contact with the transparent section; and a slide amount calculation processing unit that calculates a slide amount by displacement of a corresponding location in image information of the ground contact surface of the tire resulting from a differing load, said corresponding location corresponding to the ground contact surface of the tire measured by the ground contact force measurement processing unit.
Operability, accuracy, and safety when fitting a glass-made pipette tip to a pipette are improved. A pipette tip fitting adapter includes a hollow body having one end portion configured to serve as a tip inserting portion into which a pipette tip is inserted, and the other end portion configured to serve as a pipette inserting portion into which a pipette is inserted, and at an opening side of an inner circumferential surface of the tip inserting portion, seal portions projecting inward are formed in a circumferential direction. Accordingly, a pipette tip that is long and heavy like a glass tip can be held.
