Title: Method and apparatus for evaluating circuit
Inventor: MORISHITA TAKEMITSU
IPC: G01R31/28
Filed: 1994-03-16
Abstract: PURPOSE:To evaluate a circuit accurately based on the thermal energy generated from a circuit to be evaluated based on the structure at a specified part and the thermal energy generated based on the electromagnetic characteristics of the circuit. CONSTITUTION:When an evaluation operation is commanded at an input section 11, a data processing section 16 reads in a layout diagram from a layout diagram memory section 14 and presents the layout diagram on a display section 17. An element to be simulated is then extracted while observing the displaying section 17. The processing section 16 then creates a concentrated constant circuit diagram for the part other than the circuit elements. On the other hand, the processing section 16 reads in data for every process of element part from a process data memory section 15 and creates the structural data for the element part. Subsequently, the processing section 16 determines the quantity of heat from the thermal energy at the element part and the concentrated constant element based on the voltage and current distributions of elements in the circuit diagram and a decision of GO/NO GO is made for the circuit by comparing the quantity of heat.

Title: Optical pickup
Inventor: YOKOYAMA OSAMU
IPC: G11B7/09
Filed: 1988-02-29
Abstract: PURPOSE:To obtain an optical pickup with miniaturized, light weight, and accessible at high speed by mounting an optical system on a floating slider which floats by the shift of the substrate of a recording medium. CONSTITUTION:A convergence type grating coupler 108 consisting of a semiconductor laser 104, a photodetector, and an objective lens and the optical system consisting of an optical waveguide layer 103, etc., which connects the above devices are mounted on the floating slider 201 which floats by the shift of the substrate 303 of the recording medium. In other words, by mounting the optical system on the floating slider which floats with a constant amount of floating over the surface of the substrate of the recording medium by the rotation of the substrate of the recording medium, etc., a distance between the recording medium and the optical system can be kept constant. Therefore, it is possible to make a servo mechanism in a focusing direction unnecessary, and also, to make an electromagnetic driving mechanism for servo unnecessary for performing tracking in a direction of a feed motor like a fixed magnetic disk because the weight of one gram of the optical pickup including the floating slider is extremely light. In such a way, a recording and reproducing device can be miniaturized and operated at high speed.

Title: Machining method
Inventor: INOUE KIYOSHI
IPC: B23Q15/22
Filed: 1987-03-03
Abstract: PURPOSE:To aim at improvement in accuracy of finishing, by detecting and recording rotatory deflection of a workpiece or a tool during drilling, while making the workpiece or the toll perform its high speed reciprocation so as to compensate the deflection in synchronization with rotation during operation. CONSTITUTION:At the time of drilling, an angle of a spindle 1 is detected by an angle detector 16 and deflection of a cutting tool attached to the spindle 1 via a chuck 2 by a detector 18, respectively, and these detected data are inputted into a numerical control system 20 via encoders 17 and 19. And, the NC device 20 drives electrostrictive elements 25 and 26 on the basis of the inputted data, making a workpiece 22 perform its reciprocation in the two-axis direction of X and Y at the specified fine stroke and at high speed, and thereby the deflection of the cutting tool is compensated, while motors 29 and 30 are controlled according to the preset program, thus the desired machining takes place. Thus, even if each center of a turning shaft, the chuck and the tool is not fully accorded with one another, the workpiece or the tool is entirely compensated, so that true round cutting in drilling or the like is performable with accuracy of more than the rotatory deflection.

Abstract: PURPOSE:To cope easily with a case even when a data block length or the number of input times are changed by accumulating the number of times where a bit on the same bit location is in a prescribed state every time a data block is inputted to execute the decision by majority. CONSTITUTION:Every time a serial DATAIN is inputted in a period (t), a timing signal generating circuit 21 generates a timing signal of R/W, LOAD/CNT, and CP0-CP2. An RAM23, a memory address counter 24 and a counter 22 have an estimated maximum capacity and every time the DATAIN is inputted in the unit of bits, the counter 24 is advanced to a count value in response to a data block length to supply an address signal to the RAM23, reads a data from the RAM23 and loads it to the counter 22. Only when the DATAIN is in a specific state, the data is incremented and stored in the same address of the RAM23. The counter 22 adds accumulatingly the state where a bit in the same bit location is in a prescribed state and outputs the accumulated value to a majority decision circuit 25 after the input of final data block.

Title: Gas combustor and method for preventing fault cutoff of gas
Inventor: SHIMADA KATSUTOSHI
IPC: F23N5/24
Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To provide a gas combustor and a method for preventing the fault cutoff of gas, which is able to prevent the fault cutoff caused by a gas meter after a long-term continuous use of the gas combustor. SOLUTION: A heat source unit 10 is connected and arranged at a downstream side of a gas meter 20 which has a safety function for shutting off a gas flow path in the case where abnormality is judged as occurring at the time when a gas flow is continued substantially at a given level over a given safety continuation period of time. The heat source unit 10 comprises a hot-water heat exchanger 11, a system controller 12 and a proportional valve 19 provided at a gas tube 18. The system controller 12 changes the opening of the proportional valve 19 to forcibly alter a gas combustion amount when the hot- water heat exchanger 11 has continuously combusted while keeping substantially a given combustion amount until the arrival of time for given forcible alteration.  In this way, it is possible to avoid the situation where a long-term continuous use is erroneously regarded as abnormal by the gas meter 20 and thus gas is cut off.

IPC: G05D1/08
Filed: 1980-04-11
Abstract: PURPOSE:To control directing directions without requiring intricate arithmetic circuits by performing controlling according to the positive and negative of the respective output signals of a nonrotation type solar sensor and a geomagnetic sensor. CONSTITUTION:A nonspin type solar sensor 1 reads out the angle of the sun which is a target with respect to x-axis and y-axis and outputs Sx, Sy. The geomagnetic sensors 2 provided to the x-axis and y-axis respectively outputs geomagnetic components bx, by. These outputs Sx, Sy and bx, by are supplied to a logic control circuit 7 via processing circuits 3, 4 and 5, 6 respectively. Here, the circuit 7 flows electric current to a coil 8 only when the conditions (Sybx-Sxby)>0 hold depending upon the positive and negative of the respective signals, thereby performing controlling. Hence, the satellite is directed to the direction of the target. Since the calculation of (Sybx-Sxby) is not carried out in this way, the directing direction is controlled without requiring intricate arithmetic circuits.
