IPC: H04N1/113
Filed: 1986-07-09
Abstract: PURPOSE:To shorten significantly the time taken for stabilizing the amount of light by a method wherein the output current to control the driving current for a laser is controlled on the basis of an increased component or a decreased component and the output current is increased or decreased in every clock obtained from an oscillator and is converged into a proper value of amount of light.

This voltage signal is supplied to a microcomputer 52 after converted into a digital signal in an A/D converter 51. The digital signal is used to determine an output signal for current control, which is outputted to a D/A converter 47. In case the detected amount of light is below the set amount of light, a count-up operation is executed in order every increment A and in case the detected amount of light is above the set amount of light, a count-up operation is executed in order every increment B, where A>B. Thereby, the time required to reach the prescribed level can be significantly shortened.

IPC: H03F3/34
Filed: 1995-06-28
Abstract: PURPOSE: To provide a voltage-current conversion circuit which can perform the voltage-current conversion with use of a small number of elements. CONSTITUTION: When the input voltage VIN exceeds VIN'=Vcc×R18 /(R17 +R18 ), a 1st transistor TR Q14 is turned on and a current IOUT=(VIN-VIN')/R16 flows to the TR Q14 from a current source Vcc via a TR Q13 that constructs a 1st current mirror circuit 11. Then the current IOUT is taken out of the collector of a TR Q12 that also constructs the circuit 11. Therefore, the current IOUT is outputted only when the voltage VIN exceeds the voltage VIN' in regard of the input/output characteristic of a voltage-current conversion circuit 10.

Filed: 1995-06-28
Abstract: PURPOSE: To improve safety by proper extension of door opening time by a load detector by discriminating getting-on and off to the inside of a cage from a changing state of a load in the cage of an elevator and controlling extension of the door opening time in accordance with it. CONSTITUTION: A getting-on and off discrimination part 6 inputs a load detection signal from a load detector 4 with a constant time interval, discriminates a getting-on and off state of a cage 1 from a fluctuating state of a load in the cage 1 and carries out door opening and closing control by transmitting it to a door opening and closing control part 7. At first, whether there is a load in the cage 1 or not is detected by the load detector 4. Thereafter, when the cage 1 reaches a target floor, a door 3 is opened by driving a door motor 2, and counting of initialized door opening time is started. At this time, when there is fluctuation in the load in the cage 1, door opening extension is carried out by the door opening and closing control part 7 until the fluctuation is eliminated.  In the meantime, when there is no fluctuation, door closing is started by initialized door opening time.

Title: Start/stop control system of information processor
Inventor: SHIMAZAKI SHIGEO
IPC: G06F11/28
Filed: 1984-08-01
Abstract: PURPOSE:To reduce the number of control signal lines to relax restrictions on the number of terminals by using an input signal and the output signal of an FF as a start signal and an execution stop signal respectively. CONSTITUTION:When a signal STRT is set to the high level in the continuous execution operation, an FF54 is set, and a signal STRTF goes to the high level, and a signal HALTF goes to the low level. A control part 55 detects the high level of the signal STRT to execute one instruction. After this execution, the control part 55 confirms the low level of the signal HALTF to execute the following instruction. This operation is continued. In the successive execution operation, execution of one instruction is started when the signal STRT goes to the high level to start a device. The signal STRT is set to the low level before execution of one instruction is terminated, and the device is stopped at the instruction execution end time because the signal HALTF is in the high level. Thus, the successive execution operation is performed.

Abstract: PROBLEM TO BE SOLVED: To effectively perform air scrubbing by intermittently operating a suction pump for depressurizing the filtrate side of a membrane module while injecting air from a diffuser pipe and making the flow rate of the air from the diffuser pipe when the pump is stopped larger than that when the pump is driven. SOLUTION: Sewage to be treated is temporarily stored in a storage tank and then supplied to a tank 3 by a feed pump 42. Air is injected from diffuser pipes 51 by driving a blower 52 to spiral the sewage in the tank, a suction pump 33 is intermittently driven to depressurize the filtrate side of flat- membrane elements 1, hence the sewage is filtered, and the filtrate is sent to a storage tank 34. In this case, although the depressurization and filtration are not conducted when the pump 33 is stopped, the blower 52 is driven at a higher speed than when the pump 33 is driven to increase the flow rate of the diffused air, and the bed of activated-sludge cake depositing on the membrane surface of the element 1 is released and removed.

Title: Ignition coil
Inventor: MIWA TETSUYA
IPC: F02P15/00
Filed: 1994-07-14
Abstract: PURPOSE:To achieve the enhancement of insulation strength between a primary coil and a secondary coil using a simple constitution, by making the number of turns of the coil at both the ends of the primary coil, opposed to both the ends of the secondary coil, smaller than that in the center of the primary coil, opposed to the center of the secondary coil. CONSTITUTION:A primary coil 151 consists of a large diameter portion 151a in the center and small diameter portions 151b at both ends. The first layer of the primary coil 151 is wound to the end of winding width of a primary spool 50, and made to turn back from there. The second layer is made to turn back halfway without returning to the start point, and the third layer is also make to turn back halfway without returning to the end. Thus the fourth layer is formed until the coil reaches the turning point of the second layer, and from the point the coil sinks by two stages. That is, the height of the small diameter portions 151b on both sides is smaller by a value equal to the height of two of the layers than that of the large diameter portion 151a in the center. This provides a large distance between the primary coil and a secondary coil, and thus ensures insulation there.

Abstract: PURPOSE:To provide the method in high pressure casting to produce a casting product having undercut in insert/hollow part, into which molten metal is prevented from getting and which is capable of obtaining enough expanding/ contracting quantity and to provide the method to cast a cylinder while inserting a liner in bore. CONSTITUTION:Around a core insert 3, first pedal inserts 1a-d and second pedal inserts 2a-d are alternately placed with contacting each other. The first pedal inserts and core insert are engaged with a projecting dove tail groove and the second pedal inserts and core insert with a recessed dove tail groove. The core insert is inserted so as to expand the pedal inserts and the core insert is pulled out so as to contract the pedal inserts. Because mutual contact between the first and second pedal inserts are kept at the time of expanding/contracting pedal inserts, the molten metal is prevented from entering into insert.

Filed: 1982-09-20
Abstract: PURPOSE:To simplify the constitution of hardware for an FFT device using a pipeline type operator, by using the operator only for an operation to known non-zero value data. CONSTITUTION:While an operator 9 is carring out the butterfly processing of the 1st one between two stages, an input data selector 8 selects a bus 11 in the form of an input data, and an output data switch device 10 selects an output bus 11. As a result, the arithmetic results of butterfly processes (1)-1 and (1)-2 are stored in a data buffer 13 to be used to the input data of the next butterfly processes (1)-3 and (1)-4. At the same time, the operator P7 of the final 13th stage executes the butterfly operation to all data consisting of sets of 0 and non-0 data. An input data selector 8 of the operator P7 reads the data out of a 0 data ROM12 in the form of the output result of an operator at a preceding stage. The Fourier conversion data are obtained for the 8192 units of the input data, for example, if the outputs of the operator 9 are arranged.
