Abstract

A substrate (101) is etched by etching processing with crystal anisotropy, thereby forming a recess (104) from the main surface of the substrate (101) to the inside of the substrate (101). A side surface (105) is almost a (111) plane, and the etching hardly progresses. As a result, a cross section of the recess (104) perpendicular to the longitudinal direction has a rectangular shape. Since an opening (103) of a mask pattern (102) has a rectangular shape in a planar view, the opening of the recess (104) has a rectangular shape in a planar view, and the recess (104) is formed into, for example, a rectangular parallelepiped shape. The recess (104) includes a side surface (105) that forms one plane perpendicular to the main surface of the substrate (101). The side surface (105) is a facet surface and is a tilting surface tilted from the (111) plane.

Abstract

An optical connector cleaning tool includes a tip (44) for cleaning in a distal end portion. The tip (44) has a distal end face (51) in which a delivery hole (53) and a winding hole (54) for a cleaning medium are formed, and has an outer circumferential surface (52). The distal end face (51) has a first inclined surface (56) and a second inclined surface (57) forming the distal end portion of the tip (44) into a mountain shape in cross section, and has a convex curved surface (58) for connecting them to the outer circumferential surface (52). The first inclined surface (56) crosses an axis of the tip (44), and inclines at an angle smaller than an inclination angle of a distal end face of an APC connector. The second inclined surface (57) is formed such that an offset line (61) (a ridgeline) at the distal end of the tip (44) is positioned between the axis of the tip (44) and the winding hole (54), and inclines at an angle equal to or larger than the inclination angle of the distal end face of the APC connector. The convex curved surface (58) inclines at an angle equal to or larger than the inclination angle of the distal end face of the APC connector. This makes it possible to provide an optical connector cleaning tool capable of properly cleaning both a PC connector and an APC connector without using a rotation mechanism for rotating a tip.

The present invention comprises a cleaning tool body (3), a feeding-side bobbin (13), a cleaning head (cleaning part), a winding-side bobbin (14), a moving body (5) that moves during cleaning, a feeding mechanism (2) that feeds a cleaning medium (6) to the cleaning head in conjunction with the moving body (5) before the cleaning medium (6) is used, and a winding mechanism (21) that drives the winding-side bobbin (14). The feeding mechanism (2) moves a folded-back part in the direction away from the winding-side bobbin (14) at one location at which the cleaning medium is folded back. The winding mechanism (21) has a drive piece (28) that engages with a rotating body (25) of the winding-side bobbin (14). The drive piece (2) slips against the rotating body (25) when a load pressing an engaging protrusion (26) of the rotating body (25) reaches a predetermined overload. The predetermined overload is an overload greater than an overload caused when the feeding mechanism (2) winds up the cleaning medium (6) that has been drawn out, and is a load less than an overload caused when the winding-side bobbin (14) rotates such that the cleaning medium (6) is drawn out from the feeding-side bobbin (13). Therefore, an optical connector cleaning tool is provided which is capable of winding a cleaning medium to a certain length with a simple configuration and in which resistance when the cleaning medium is drawn out to the certain length is reduced.

Abstract

A spread spectrum modulation unit (12) subjects a basic clock signal (BC) synchronized with the carrier frequency or the harmonic frequency thereof of image information leaked with unnecessary electromagnetic waves to a spread spectrum clocking process. A modulation pattern generation unit (13) generates a PN code wherein code bit data is synchronized with each pulse of the obtained spread spectrum clock signal (SC), outputs the PN code as a modulation pattern signal (MP), and resets the repetitive frequency of the PN code with a horizontal synchronization signal (H). A modulated clock generation unit (14) modulates the spread spectrum clock signal (SC) with the modulation pattern signal (MP) and amplifies the obtained modulated clock signal (MC) to generate a leakage prevention signal (JC). This enables to generate the leakage prevention signal containing complementary components at a sufficient level, and thereby a useful leakage prevention effect can be obtained.

The retaining means (2) comprises a tubular retainer (10), a tubular body (12) disposed within the retainer (10) rotatably, and movably in an axial direction, a spring for biasing the body (12) in a forward direction and so forth. The retainer (10) is provided with a pair of resilient pieces (16), and on inner sides of the resilient pieces (16), guiding protrusions are respectively provided. Around a periphery of the body (12), spiral grooves (25, 26) to be engaged with the respective guiding protrusions are formed over an angular range of 360°. Accordingly, when the retainer (10) is moved forward, the body (12) moves rotationally forward due to the behavior between the guiding protrusions and the spiral grooves (25, 26). The cleaning means (5) comprises a cleaning thread (41) provided within a rotating pod (40), a supply reel, a wind reel, a rotational axis and the like, and it is coupled to the body (12). Accordingly, when the body (12) rotates, the rotating pod (40) and the rotational axis rotate to cause the cleaning thread (41) that has been pulled out over an end surface of a cleaning section (S) of the rotational axis to clean a connecting surface (4a or 91a) of the optical connector (3 or 90). The rotating pod (40) pulls out the cleaning thread (41) from the supply reel and winds it into the wind reel through rotation.

Abstract

In order to increase the diffraction efficiency by forming a multi-layer film on a laminar type diffraction grating surface, it is necessary to satisfy four conditions: [1] condition of a groove depth capable of obtaining the optimal reflectivity; [2] extension Bragg condition of the multi-layer film; [3] condition expression defining correlation between directions of an incident light and a diffracted light; and [4] a ratio of the width of convex portion against the concave portion on the laminar type diffraction grating surface. However, there has been no unified design guideline. The present invention solves this problem by giving a general design guideline and an optimal multi-layer substance pair so as to provide a diffraction grating having both of a high diffraction efficiency and a high resolution in the wavelength region of 0.1 to 1 nm where spectroscopy using a diffraction grating is difficult because of the efficiency lowering.
