IPC: G02B6/42
Filed: 1989-05-29
Abstract: PURPOSE:To obtain the small-sized optical coupling part which is easily aligned by putting the active layers of a light emitting and a receiving element closely opposite each other. CONSTITUTION:The end surface incidence type light receiving element 11 has the beltlike active layer 11a formed on one surface of a crystal substrate to the overall length of the substrate and the light emitting element 12 has the active layer 12a formed on one surface of the crystal substrate to the same size corresponding to the active layer 11a of the light emitting element 11 and the light receiving element 1 and light emitting element 12 are so arranged that the active layers 11a and 12a of the light receiving element 11 and light emitting element 12 face each other at an interval (d) of about 10 mum in parallel and the end surface where the active layer 11a of the light receiving element 11 and the end surface 12b where the section of the active layer 12a of the light emitting element 12 is exposed are on the same plane. Namely, end surfaces of grated index fibers are put closely opposite each other in parallel on the surfaces formed of the light reception area 11c and light emission area 12c so that the optical fiber axes of the grated index fibers meet each other almost at the mid-point between the light reception area 11c and light emission area 12c. Consequently, the optical coupling part which is easily aligned is obtained.

Title: Picture reader
Inventor: YOKOMIZO YOSHIKAZU
IPC: H04N5/335
Filed: 1979-10-20
Abstract: PURPOSE: To hold the voltage level of a video signal invariably constant by adding a corrected voltage to the output voltage of a solid-state image element and then by holding this corrected voltage.  
     CONSTITUTION: At the time position of the black level, counter 10 generates sampling pulse ϕD. Consequently, as analog switch 8 turns on to form a black-level stabilizing loop, output signal VO of video amplifier 4 flows into integrator 5, which starts integration. Then, black-level signal VD generated by variable resistor 7 is compared with signal VO and if VO is lower, the output of integrator 5 increases. When signal VO agress with VD, the output of in tegrator 5 is unchanged and VO is clamped at VD. When any pulse ϕD is no applied to switch 8 from circuit 10, integral capacitor 6 holds the corrected voltage and signal VO stays clamped at VD. Thus, the corrected voltage is held during the signal output period from the picture area, so that the video signal level from the image pickup element can be stabilized.

Filed: 1994-06-17
Abstract: PURPOSE:To reduce size and weight and to increase an output by providing a casing formed integrally with two cylinders positioned radially facing each other, a positive motion cam having the odd number of cam crests, being three or more cam crests, arranged at equal intervals in a peripheral direction, a cam follower making rolling contact with a cam surface, and a coupling rod to intercouple pistons. CONSTITUTION:An output shaft is rotated by a starter and when a cam 4 is rotated counterclockwise, a piston 7 climbs a cam crest 4a for rise by a driven cam follower 10, air-fuel mixture of gasoline and air sucked in a cylinder 3 is compressed and the piston ascends to a top dead center. In this position, the air-fuel mixture is ignited for explosion and expansion through which the piston 7 is forcibly pressed down and during re-rise, combustion gas is exhausted. During lowering of the piston 7, the fuel-air mixture is sucked, the piston climbs a cam crest 4c for compression, and the piston descends owing to explosion and expansion and is restored to an initial state. Since, as noted above, six full stroke cycles per one full turn of the cam 4 are carried out. When explosion is effected at least two times, high output torque is generated by reduced size and weight.

Filed: 1992-04-27
Abstract: PURPOSE:To obtain a sensor, which has high alcohol selectivity and small humidity dependence, by using a metal oxide semiconductor, wherein tungsten oxide and vanadium oxide are mixed in the specified range in the atomic ratio of tungsten and vanadium, as the main component. CONSTITUTION:The main component of an alcohol sensor is a metal oxide semiconductor, wherein tungsten oxide and vanadium oxide are mixed in the range of 99:1-85:15 in the atomic ratio of tungsten and vanadium. As for the effects of the vanadium (V), there is the large difference between the V content of 0.5-1%, and the resistance value is decreased and the temperature and humidity dependence and the ethanol selectivity are impvoed at 1%. Meanwhile, the gas concentration dependence is decreased. At the V content of 25%, the resistance value is decreased, the temperature and humidity dependence and the ethanol selectivity are deteriorated and the gas-concentration dependence is decrased. Therefore, the practical ranges as the alcohol sensor are limited in 1:99-15:85, more preferably 2:98-10:90 in the atomic ratio of V/W.

Title: Manufacturing method of photoelectric semiconductor converter
Inventor: IGAWA YASUO
IPC: H01L31/10
Filed: 1978-11-08
Abstract: PURPOSE: To prevent the deterioration of properties due to leakage current, by selectively oxidizing the intergranular part of a polycrystalline silicon substrate to insulate the part.  
     CONSTITUTION: An n-type silicon crystal piece having numerous crystal boundaries is electrolytically etched in a solution of hydrofluoric acid or the like while an anode of polycrystalline silicon, a cathode of platinum and DC power are applied. Since the crystal boundary part 72 is inverted to the p-type, the etching speed of the part is higher than that of the other n-type part and a porous silicon layer 73 is produced. The silicon crystal piece is then treated with heat at a temperature of 1,100°C to oxidize the porous layer. A pn junction solar battery is made of the silicon crystal piece. This results in reducing a leakage current which flows from the p-type part through the inverted layer near the crystal boundary. The conversion efficiency is thus raised.
