3, both inclusively. One principal surface of the substrate is irradiated with protons and then heat-treated to thereby form a broad buffer structure, namely a region in a first semiconductor layer where a net impurity doping concentration is locally maximized.

A magnetic short-circuiting plate (16) for reducing a quantity of a magnetic flux to be generated from a permanent magnet (9) is mounted between magnetic plates (11, 12) in the case of having an electromagnetic device operate for constant excitation, and the magnetic short-circuiting plate (16) is removed from the electromagnetic device in the case of having the electromagnetic device operate as an electromagnetic latch.
A door driving apparatus includes a rotary actuator, a rotary transmission member integrally fixed to an output shaft extending from the rotary actuator, and a pair of linear transmission members opposed to each other via the rotary transmission member. The linear transmission members are configured to be in mesh with the rotary transmission member and to move approximately parallel to each other in opposite directions.
A switching power supply has a start-up circuit that includes a field effect transistor (JFET), which has a gate region (a p-type well region) formed in a surface layer of a p-type substrate and a drift region (a first n-type well region). A plurality of source regions (second n-type well regions) are formed circumferentially around the drift region. A drain region (a third n-type well region) is formed centrally of the source region. The drain region and the source regions can be formed at the same time. A metal wiring of the source electrode wiring connected to source regions is divided into at least two groups to form at least two junction field effect transistors.

A semiconductor device is discloses that includes an n-type semiconductor substrate; an alternating conductivity type layer on semiconductor substrate, the alternating conductivity type layer including n-type drift regions and p-type partition regions arranged alternately; p-type channel regions on the alternating conductivity type layer; and trenches formed from the surfaces of the p-type channel regions down to respective n-type drift regions. The bottom of each trench is over the pn-junction between the p-type partition region and the n-type drift region. The semiconductor device facilitates preventing the on-resistance from increasing, obtaining a higher breakdown voltage, and reducing the variations caused in the characteristics thereof.
A Doppler frequency distribution measuring part (11) measures a Doppler shift frequency distribution. A frequency distribution correcting part (12) determines a part of the Doppler shift frequency distribution that is affected by 'aliasing', and corrects the measurement value of the Doppler shift frequency of that part, thereby obtaining a correct Doppler shift frequency distribution. When the actual value of the Doppler shift frequency exceeds a measurement limit defined by the repetition frequency, the measurement value is a value as affected by the 'aliasing'.
