Title: Analog-to-digital converter
Inventor: TAKAHASHI TOORU
IPC: H03M1/18
Filed: 1981-07-06
Abstract: PURPOSE:To obtain a converter with high resolution by subtracting an appropriate standard signal selected in response to an output of a load cell from the output, converting the subtracted signal into a digital output by an AD converter with low resolution and then adding a digitized standard signal to said digital output. CONSTITUTION:An appropriate standard signal selected from the previously fixed standard signals is subtracted at 4 from an analog output of a load cell 2, the subtracted output is converted into a digital output by an inexpensive AD converter 1 with low resolution and a digitized standard signal is added at 6 to the digital output to output the added signal. Each standard signal is selected so that the subtracted output can be converted by the AD converter 1. These standard signal and digital standard signal are selected by a control circuit 9 on the basis of the results obtained by comparing the outputs of the load cell 2 with another standard signal corresponding to each output by comparators 7-1, 7-2...7-n. By said constitution, an AD converter with high resolution can be obtained in reasonable cost.

Filed: 1979-08-21
Abstract: PURPOSE:To speed up the readout speed, by feeding back the output data of selected memory cell to the write-in amplifier section and controlling the bit line potential at ON and OFF sides of the memory cell. CONSTITUTION:For example, when the cell MC1 is selected and the transistor TC11 is ON, the current switches TS1, TS2 of the feedback section FB to the sense amplifier WA are made ON or OFF with the ouput of the transistors TR5, TR6. Accordingly, one of the control voltage by the output current of the amplifier WA is at high level and another is at low level, and the bit  lines B1, B2 are respectively at high and low potential via the transistors TR1, TR2 according to the memory state of the cell MC1. Further, when the memory cell MC2 in which the transistor TC23 is ON-memory-state is seleceted, the potential of the bit lines B1, B2 is similarly controlled. In this case, the time when the transistor TC23 is ON is reduced according to the control voltage difference in comparison with constant bit line control voltage, allowing to speed up the readout speed.

Title: Bus tracer
Inventor: OSHIKAWA KAZUNORI
IPC: G06F11/34
Filed: 1989-04-26
Abstract: PURPOSE:To make it needless to trace a useless even, and to reduce memory capacity by providing a trace controlling means, and designating the trace of a target event. CONSTITUTION:A microprocessor 5 sets the kind of transfer to be traced in a trace mode register 4, and sets a trigger condition in a trigger mode register 3. A trace control circuit 2 interprets the control signal of a system bus A, and when it comes under a condition corresponding to the designated kind of the transfer, it sends a trace enable signal B to a memory device. On the other hand, a trigger control circuit 1 monitors the signal of the system bus A, and when it coincides with a trace stopping condition set in the register 3, it outputs an interruption signal H and a trigger condition realization signal D. Thus, since the kind of the data transfer can be selected optionally, other data having no concern can be left untraced, and a memory can be saved.

IPC: E03F5/04
Filed: 1999-04-14
Abstract: PROBLEM TO BE SOLVED: To provide a laying structure in which the sliding operation of a sliding cover is conducted easily. SOLUTION: The opening of a tank is divided into two by a beam member 4. The sliding cover 1 and a supporting cover are arranged mutually in the same opening, and the sliding covers 1 are adjoined mutually, crossing over the beam members 4 between the adjacent openings. The sliding covers 1 have inclined sections 1b, in which surfaces are directed downwards, at side edges vertical in the sliding direction.

When the siding covers 1 are pulled up onto the adjacent sliding covers 1, the pulling-up is conducted easily by the action of the inclined sections 1b formed at the side edges of the sliding covers 1 and the inclined sections formed to the inclined members 6. The imprudent movement of the sliding covers 1 is controlled by the inclined members 6, and a fall in the layer of the cover due to the displacement of each cover can also be prevented.

Filed: 1992-04-27
Abstract: PURPOSE:To allow the system to easily cope with even an increase in a call unit in the electronic exchange system in which communication terminal equipments make communication via a time division exchange bus. CONSTITUTION:A caller side time slot designation section 53 designates a time slot number used for inter-communication on an exchange bus 41 between communication terminal equipments 21, 22 connected to the exchange bus 41 and a control bus 42, and the caller side microprocessor 55 sends the information to a called side microprocessor 55 as a communication condition inquiry signal.

Title: Speed control circuit for compact dc motor
Inventor: FURUYA MISAO
IPC: H02P7/288
Filed: 1981-07-09
Abstract: PURPOSE:To prevent hunting by connecting a resistor between a first current mirror circuit which is constituted by a plurality of transistors whose emitter areas for driving a DC motor are different and a second current mirror circuit. CONSTITUTION:When the VCE of the transistors Q1 and Q2 reaches the vicinity of a saturating region due to some reason, collector currents IK and IC2 begins to decrease. Since the decreasing rate of the IC2 is large, change occurs in the direction so that K(=IM/IK) becomes small. The gradient of the current IK becomes a curve IK expressed by a VCE-IC characteristic diagram owing to the occurrence of voltage drop in the vicinity of the saturated region due to the resistor R. That is, since the collector current IK of the transistor Q1 decreases due to the resistor R in the saturating region, the ratio between IK and IC2 is almost unchanged. Therefore excessive control is not performed, hunting is not generated, and the stable speed control of the motor M can be performed.
