Title: Test pattern memory circuit
Inventor: YOSHIZAKIYA YOSHIO
IPC: G01R31/3183
Filed: 1987-06-12
Abstract: PURPOSE:To shorten the access time for memories to a large extent, by writing the data from the next external bus line into a first memory during the time data are transferred to a second memory from a shift register. CONSTITUTION:Data, which are written in a memory 3, are stored into a shift register 4 in parallel. The shift register 4 transfers the stored data into a high speed memory 5. At the same time when the data are transferred to the high speed memory 5, a low speed memory 1 writes the data in the next cycle in the memory 3. After the data of 16 bits in the shift register 4 are transferred into the high speed memory 5, the data of the next 16 bits, which are newly written in the memory 3, are stored into the shift register 4 again. Hereinafter, the same procedure is repeated. When the contents of the high speed memory 5 reach its capacity, the operation is stopped. Since the data are written in an interleave method, the access time of the memories can be shortened to a large extent.

Title: Digital controller
Inventor: ONO KOJI
IPC: G05B9/02
Filed: 1985-07-04
Abstract: PURPOSE:To prevent the runaway of a controlled system due to abnormality by determining whether a control system is in proper operation or not by an abnormality detector, and using the output of a servocontrol circuit as a controlled variable when the operation is normal and stopping the control system when abnormal. CONSTITUTION:Deviation pressure En3 is deviation between target position data Xn1 and the position thetan2 of the controlled system. The servocontrol circuit 12 inputs the deviation En3 and realizes a control rule for determining a controlled variable In5 for optimizing an evaluation function depending upon the system. The abnormality detector 13 decides whether the control system is normal or not on the basis of the position thetan2 of the controlled system and controlled variable In5 and outputs an error signal 14. A selector 15 selects the output 16 of the servocontrol circuit 12 as the output of the error signal 14 when the control system is normal or switches the controlled variable 5 and stops the controlled system when abnormal, thereby suppressing the runaway of the control system.

IPC: G06F17/50
Filed: 1992-06-08
Abstract: PURPOSE:To provide a multidimensional data high speed interpolation processor which can retrieve multidimensional data required for an arithmetic processing at high speed in a multidimensional data interpolation processing and in which the processing time of an interpolation value is short. CONSTITUTION:Equal distance data and an inclination between respective pieces of data as the coefficient and a reference value are previously obtained from multidimensional unequal interval data and they are preserved in a table 4. In an actual interpolation processing, a position to be interpolated can be instantaneously obtained by multiplying the reciprocal of pitch width which is used at the time of generating 2 equal interval data, and they can easily be obtained by an inclination and the reference value, which are read from the table 4, as to an interpolation operation.

Abstract: PROBLEM TO BE SOLVED: To prevent the forgetting of shutting off of a hot water supply plug at the destination of a hot water supply pipe line, by deciding the order of completion of delivery of hot water within a hot water storage tank, and not shutting off the hot water supply pipe line completely even if the delivery of the hot water within all hot water storage tanks is completed, in case that a plurality of hot water storage tanks are connected and used in parallel. SOLUTION: A water supply pipe line 15 and a hot water supply pipe line 16 are connected in parallel with a plurality of hot water storage tanks 12a and 12b. The water supply pipe line 15 of one hot water storage tank 12a is provided with a flow limiting means 19 which limits the flow of water supply or hot water supply to be small.

Title: Phase error detecting device for torary head device
Inventor: MATSUI HIROKI
IPC: H04N5/7826
Filed: 1990-06-07
Abstract: PURPOSE:To digitize a rotational phase error detecting function, to compact the constitution of the phase error detecting device and to reduce the production cost of the device by comparing the phase of a frequency dividing output with a reference phase and outputting a phase error. CONSTITUTION:An 1/n frequency divider 23 to which a reproducing horizontal synchronizing signal HSY supplied through a terminal 3 is supplied is provided with a reset terminal to receive a vertical synchronizing signal VSY. After dividing the frequency of the signal HSY into 1/n by the frequency divider 23, the frequency-divided signal is sent to a latch circuit 25 and the output of an adder 28 is sent to a comparator 33 as the reproducing phase information phiSY of the signal HSY. Thereby, the processing frequency of each constitutional element can be reduced, and since the frequency dividing means is reset by the signal VSY, the malfunction of the phase error detection of a horizontal synchronizing signal more than the period can be suppressed. Consequently, the phase error detecting function can be inexpensively digitized by the compact constitution.

Title: Protective circuit of power transistor
Inventor: HAGIWARA YOSUKE
IPC: H01L27/04
Filed: 1999-05-26
Abstract: PROBLEM TO BE SOLVED: To provide a protective circuit with enhanced protecting effect of a power transistor with respect to an overvoltage. SOLUTION: A detection resistor R is connected in series with a power transistor Q1. The potential across the detection resistor R is applied between the gate and source of a protective MOSFET Q3. The anode of a diode D1 is connected to a connecting point between the source of the power transistor Q1 and the one end of the resistor R, and the cathode is connected to the gate of the MOSFET Q3. The drain of the MOSFET Q3 is connected to the gate of the power transistor Q1, and the source is connected to the other end of the resistor R. When the drain voltage of the power transistor becomes excessive, the MOSFET Q3 is turned electrically conductive, and a current passing through the power transistor Q1 is restrained.  At this point, although the potential across the resistor R drops down, since the accumulated charge of the gate/source of the MOSFET Q3 is prevented from being discharged by the diode D1, a current restraining time interval t2 is prolonged.
