IPC: H01L31/10
Filed: 1981-09-21
Abstract: PURPOSE:To facilitate the detection of an object and also the detection of the transfer  direction when using to detect the transfer object and enable the miniaturization of a  device, by providing two light receiving element regions so as to operate differentially. CONSTITUTION:The p type semiconductor layer formed on an n type semiconductor  substrate 1 is divided into a first p type semiconductor region 2a and a second region  2b by a groove 11 formed by etching, etc. resulting in the constitution of a first light receiving element region 3a and a second region 3b. The first and second light receiving element regions 3a, 3b are connected in series so as to be in reverse directions  each other, and a load resistor R is connected between first and second electrodes 5a,  5b. When light is irradiatd as shown in a broken line arrow only onto the first light  receiving element region 3a, the electromotive force in the direction of the arrow A,  and, since the second light receiving element region 3b is in the forward direction to  this electro motive force, the current I in the direction of the arrow A flows to the load R. When light is irradiated only onto the second light receiving element region  3b, the current I flows to the load R in the direction of the arrow B. When light is  irradiated onto the first and second light receiving element regions 3a, 3b, the electro motive forces in the directions of the arrows A, B are simultaneously generated without the current flow to the load R.

Title: Air suspension control device
Inventor: MISAWA MASAYA
IPC: B60G17/015
Filed: 1997-05-24
Abstract: PROBLEM TO BE SOLVED: To eliminate wasteful air consumption by judging whether a car is running or stopped by a method capable of positively judging a car travel even when it travels at an extremely low speed, allowing air-springs to be air-controlled in response to the change in car height when the car is stopped, and avoiding the air-control in relation to the short-time change in car height, which is immediately restored when the car is running. SOLUTION: The car heights are sampling-detected by a car height detector 11, and stored in a detected car height value storage-memory 17. Air-control of air springs 12A, 12B is performed by controlling solenoid valves 9A, 9B by a control unit 16. Whether a car is stopped or running, is judged by whether a car speed detecting pulse from a car speed sensor 8 is interrupted or not. When the car is stopped, the detected car heights are compared to a reference car height, and air-controlled to reach the reference car height. When the car is running, an average car height in a specified period of time is determined based on the stored detected car height values, and air-controlled so as to reach the reference car height. Thus, the need for allowing the air-control to frequently respond to the change in car height, which is immediately restored, is reduced.

IPC: G06F13/12
Filed: 1989-06-14
Abstract: PURPOSE:To reduce a hardware quantity and to perform communication among plural channel devices at a high speed by connecting plural channel devices in serial loop connection. CONSTITUTION:A channel device 5 sends the host address of a communication destination and the communication data to a communication control part 21 in response to the instruction of a controller of a host system 1 and inserts the delimiters into the positions before and after a data frame to send the data to a loop connection part 22. The part 22 sends the data frame to a channel device 6 via an interface signal line 10 and sends the data frame to a channel device 7 when its own address is not designated at a transmission destination address part. The device 7 sends the received data frame to the part 21 from the part 22 when the transmission destination address part designates the address of a host system 3. Then the part 21 sends a transmission originating address part and a data part to the system 3 via a channel controller interface part 20.

Title: Quadrature detector
Inventor: OOTAKI KIYOSHI
IPC: H03D3/00
Filed: 1983-08-19
Abstract: PURPOSE:To obtain a quadrature circuit with simple adjustment and less distortion by adding a distortion cancellation circuit to a single tuning circuit. CONSTITUTION:An output of a multiplier 3 is given to one input of an adder 9, both inputs of a multiplier 6 and one input of a multiplier 7. The output of the multiplier 6 is given to the other input of the multiplier 7 and the output of the multiplier 7 is given to the input of an attenuator 8. Further, the output of the attenuator 8 is given to the other input of an adder 9 and the output of the adder 9 becomes a detected output 4. A square term of the output of the multiplier 3 is obtained at the output of the multiplier 6. Since the fundamental and the square term of the fundamental wave are applied to the input of the multiplier 7, a cube term of the fundamental wave is obtained at the output. Thus, a waveform from which the 3rd harmonic is cancelled is obtained by subtracting the cube term from the output of the multiplier 3 by means of the adder 9.

Title: Automatic gain control circuit
Inventor: UNOSAWA SUSUMU
IPC: H03G3/30
Filed: 1989-06-13
Abstract: PURPOSE:To attain the automatic gain control of a signal with an intermittent carrier signal by extracting an average amplitude in a prescribed time of a specific frequency component in a signal inputted discontinuously to use the result as a gain control signal for the succeeding signal, and using a preceding gain control signal to control a prescribed gain till the succeeding gain control signal is extracted. CONSTITUTION:A frequency discrimination circuit 3 extracts only a specific frequency component of an input signal and an AM detection circuit 4 outputs an envelope to extract the amplitude component of the output signal. On the other hand, when a counter circuit 6 detects a prescribed extracted component, the signal being the result of count acts on a multivibrator circuit 8 to generate a pulse for a prescribed time, the pulse is supplied to the AM detection circuit 4, which outputs the amplitude of an envelope, the amplitude is used as a sampling time in the pulse generating time, and the amplitude for the non-pulse generating time is used as a hold time, and the sample-and-hold output acts on an amplifier 2 as a gain control signal. Thus, signal distortion of an input signal without consecutive carrier signal is less.

Title: Controlling method for inductor for agitation of molten metal
Inventor: HOSHIKA HARUO
IPC: B22D11/115
Filed: 1981-09-24
Abstract: PURPOSE:To change the agitating speed for molten metal and the penetration depth of magnetic fluxes in the molten metal to prescribed values according to the level of the molten metal  by changing the frequencies of the electric power to be applied to the inductor for agitation  of molten metal disposed in the bottom part of a furnace body which holds the molten metal  according to the level of the molten metal. CONSTITUTION:For example, in the case of charging Al scraps into a reverberatory furnace 1  and melting the same, high speed agitation is recommended and when the total accumulated  amt. of the molten metal in the furnace increases, low speed agitation is preferred. Thereupon,  a level sensor 11 outputs a level signal of molten metal 2, and according to said signal, a  setter 12 outputs a signal for regulation of frequencies. The alternating electric power of adequate variable frequencies meeting the amt. of the molten metal is supplied from a control  circuit 14 for electric power to an inductor 4. When the level of the molten metal is low, the  output frequency to the inductor 4 is increased by the output of the sensor 11, and the progression speed of the shifting magnetic field generated from the inductor 4 is fast and the penetration depth to the molten metals shallow. When the level of the molten metal rises, the frequencies are made low and the opposite takes place. Thus the efficiency of melting is improved, the accelerated oxidation of the molten metal is prevented and the efficiency of the  agitation is improved.
