Patent JP-S5511382-A (JP)
Title: Semiconductor
Inventor: SUZUKI KOUICHI
IPC: H01L21/337
Filed: 1978-07-11
Abstract: PURPOSE:To obtain a constant current source by setting the distance between gate and source so that a parasitic resistor equal to VGS/ID wherein the drain current and the value at the intersection of the chracteristic curves of the voltage between gate and source that are obtained when ambient temperature is changed with the voltage between drain and source kept constant are ID and VGS1 respectively may be formed between gate and source. CONSTITUTION:When ambient temperature is changed with the voltage between drain and source kept constant, the chracteristic curves of the drain current - voltage between gate and source intersect each other almost at a point (ID, VGS1), and the variation of drain current by temperature is minimum at the point. By utilizing this, voltage VGS1 and current ID can be maintained at selt-saturation bias at a source earthing type circuit by means of a resistor RS. The setting of said resistor RS can be made in terms of the distance between gate and source layer.

Title: Compression connecting method for conductors
Inventor: AIDA KAZUO
IPC: H01R4/20
Filed: 1988-04-07
Abstract: PURPOSE:To prevent the generation of a recess following the compression of the surface of a conductor connection tube by compressing the center of the conductor connection tube temporarily, and then, compressing the temporarily compressed part principally, after compressing the both ends principally. CONSTITUTION:A pair of conductors 1 and 1 to connect are inserted and opposed in a conductor connection tube 2. Then, the center part a of the connection tube 2 is compressed temporarily by using a die 3. After that, both ends b and c of the connection tube 2 in the uncompressed condition are compressed principally by using dies 3 to compress a specific amount alpha by overlapping to the part a already compressed temporarily in the former process. And finally, the part a is compressed principally. In this case, the difference in level between the part a and the parts b and c can be made small because the part a is already compressed temporarily, and the difference in level generated by compressing a large difference in level can be reduced. The generation of a recess can be prevented consequently.

Title: Manual aperture value setting system of lens interchangeable type camera
Inventor: NAKAI MASAAKI
IPC: G03B7/091
Filed: 1984-04-26
Abstract: PURPOSE:To rationalize the whole system and to simplify the constitution of an interchangeable lens which has a stop device, but is not provided with a manual operation member for aperture setting, and a transmission means which transmits a stop-down quantity to the stop device. CONSTITUTION:When the lens is mounted, the stop-down pin 9 of the lens side abuts on a part 15a of a stop-down control part 15 and a stop aperture is therefore determined according to the position of this member 15. The stop-down control member 15 is energized by a spring as shown by an arrow X, but locked as shown in a figure except during exposure control operation, so the stop is set to an open aperture. Once the exposure control operation is started, The stop-down control member is unlocked and begins to move as shown by the arrow X and the stop-down pin 9 follows it up and moves as shown by an arrow Z to stop- down the lens. Then when the control member 15 moves by an expected number of stop-down stages, the stop-down control member 15 is locked and the stop- down pin 9 which moves following it up is also locked, thus determining a stop aperture.

Abstract: PROBLEM TO BE SOLVED: To accurately control a position of a wave transmitter by setting a plurality of wave receivers for receiving signals from the wave transmitter, correlating signals received by each pair of selected wave receivers, calculating a median of the wave receivers, and controlling a position of the wave transmitter on the median. SOLUTION: Direct waves 16 propagating in water are received at wave receivers 2-5. The four wave receivers 2-5 are arranged symmetrically in an up-down direction and a right-left direction. Received signals of the two wave receivers 2, 3 positioned symmetrically in the up-down direction are correlated by a correlating circuit 6 and taken into a control device 13, where a difference of propagation times of the two received signals is detected. An operation signal is generated so that the difference, namely, time difference becomes close to zero. The operation signal is fed back to a driving device 14 and a propeller device 15, thereby controlling a movement of a wave transmitter 1 in a depthwise direction.  Received signals of the two wave receivers 4, 5 at symmetric positions in the right-left direction are taken in a correlating circuit 7, thereby controlling the movement of the wave transmitter 1 in a horizontal direction. The wave transmitter is positioned on an intersection of vertical bisecting faces of the wave receivers 2, 3 and 4, 5, i.e., a median.

CONSTITUTION:When the maximum output load exists, the control input IC1 of a transistor Q11, and the control input IC2 of a Q12 are set at H levels, and when a signal input Is is set at the H level. two amplifying transistors Q21 and Q22 are operated, an the maximum current is supplied to the base of the output transistor Q3. When the output load with less than the half of the maximum current exists, the control input IC1 of the Q11 is set at the H level, and the control input IC2 of the Q12 at an L level. In such a way, when the signal input Is is set at the H level, the Q21 is turned ON, and the Q22 is turned OFF, and the base current of the Q3 is operated with the current with around the half of the current at the time of maximum load. Therefore, it is possible not only to prevent the oversaturation of the output transistor Q3 but to reduce the power consumption.
