Title: Insulating gate type four-electrode field effect transistor
Inventor: KANBARA MINORU
IPC: H01L29/78
Filed: 1985-06-28
Abstract: PURPOSE:To decrease distortion in output signal to a large extent, by changing the impurity concentration of a channel along the direction of the width of a gate. CONSTITUTION:The impurity concentration in a channel beneath a first gate electrode 11 has the concentration inclination in the direction of A-A'. The impurity concentration of a channel beneath a second gate electrode 12 has the concentration inclination in the direction of B-B'. For example, the impurity concentrations are formed in three stages, i.e., 1X10<16>cm<-3> (curve 33), 5X10<15>cm<-3> (curve 32) and 1X10<15>cm<-3> (curve 31) in the directions of A-A' and B-B'. The impurity concentration characteristic curves 33, 32 and 31 are obtained as shown in the Figure. The total characteristic curve in this embodiment is shown by 34. Thus mutual conductance becomes constant. The insulating gate type field effect transistor, whose gate bias range is broad, can be obtained.

Abstract: PURPOSE:To obtain a strong light source and to measure a long distance to an object such as a preceding vehicle at the time of high-speed running by a method wherein a plurality of xenon flash discharge tubes are made to flash and emit light as light sources sequentially and measurement of the distance is executed synchronously therewith. CONSTITUTION:A plurality of xenon discharge tubes 31 each provided, in the front, with a condenser lens 34 and a filter 33 cutting off a visible light and transmitting an infrared light are so disposed as to face in the same direction. These discharge tubes 31 are made to emit light sequentially and measurement of a distance is executed synchronously with the emission. On the occasion, measured-distance data which cause no hindrance practically, although being intermittent measured values, can be obtained. Besides, a visible light out of the emission from the discharge tubes 31 is cut off by the filter 33, and therefore no man is dazzled thereby even when he is present in the flashing direction. Accordingly, strong light sources are obtained and measurement of a long distance to an object such as a preceding vehicle in high-speed running can be executed.
