Filed: 1989-05-15
Abstract: PURPOSE:To use two kinds of interface circuits with switching by forming an output circuit with a couple of switching elements connected in series between a power level and a reference level and bypassing a driving signal of the switching element at the power level side toward the reference level with an external signal. CONSTITUTION:A final stage output circuit 1 consists of a couple of transistors(TRs) Q1 and Q2 driven complementarily and connected in series between a power level and a reference level and a transmission control circuit 4 bypassing only an ON/OFF driving signal of the TR Q1 connecting to the power level side toward the reference level side selectively in response to the signal given externally is provided. Thus, two kinds of interface circuits are used switchingly for a current output type circuit applying current source and a switch output type circuit with only current sink by means of one kind of the circuit, then the degree of freedom of the constitution of the external load circuit is extended to enhance the general-purpose performance of the semiconductor integrated circuit device.

Title: Semaphore operation system
Inventor: KUBO HITOSHI
IPC: G06F9/52
Filed: 1989-05-16
Abstract: PURPOSE:To simply execute priority control in the exclusive control of resources, to reduce the overhead of software and to improve the performance of a system by setting priority in a semaphore. CONSTITUTION:In a P-operation (occupied operation), for example, '1' is subtracted from the semaphore counter 2 of a target semaphore 1. When a number is positive or '0', the P-operation is assumed to be succeeded and priority which is set in a semaphore setting area 4 is compared with the priority of the executed process (priority saved in a process priority saving area 5). When priority which is set in the semaphore 1 is high, the priority of the process is changed to the setting priority of the semaphore so as to raise priority, and an operation can be executed by the priority. Thus, priority control by the exclusive control of the resources is realized and the overhead of software is reduced, whereby the performance of the system is improved.

IPC: G06K9/00
Filed: 1986-05-28
Abstract: PURPOSE:To decide a direction by a small number of times of an arithmetic operation, and to remarkably shorten the processing time by adopting a prescribed parameter, and obtaining the information of the direction from calculating this parameter. CONSTITUTION:First of all, center-of-gravity coordinates xG, yG and an inclination theta in a visual angle coordinate system XOY are calculated. In case of only these two information, two kinds of attitudes as shown by a full line and a broken line, respectively exist. Therefore, in order to obtain the information of a direction, R and (n) are set to prescribed values, and subsequently, coordinates xa0, ya0 of a0 and coordinates xb0, yb0 of b0 are drawn out of a table which has been generated in advance. Subsequently, distances Ga0, Gb0 from the center of gravity are derived, and from its result, R0 is derived, and also, R is derived. Whether a value of this calculated R is R<0.9 or R>1.1 is checked, and in case of R<0.9, it is decided to be a direction as shown by the full line, and in case of R>1.1, it is decided to be a direction as shown by the broken line, and in case of 0.9<=R<=1.1, (n) is updated, and by executing the same process, a loop is repeated until R<0.9 or R>1.1 is obtained. In such way, the processing time can be shortened remarkably.

Title: Measuring device for electronic watch
Inventor: UEDA JIYUN
IPC: G04C3/14
Filed: 1978-10-04
Abstract: PURPOSE: To shorten the measuring time for the watch rough torque by setting freely the frequency for the driving pulse and the auxiliary driving pulse of the torque motor and then measuring the load state of the step motor.  
     CONSTITUTION: Control circuit 300 generates the driving pulse and the auxiliary driving pulse based on the time reference pulse sent from time reference oscillation circuit 304, and step motor 302 is driven by either of the two pulses. The rotation and non-rotation of motor 302 are displayed at display unit 306 via the induced voltage of the specified pattern produced at the driving coil of motor 302 in accordance with vibrations of the rotor caused by the damping at the rotation time of motor 302. And in the case of non-rotation of the motor, the pulse to be applied to motor 302 from circuit 300 via operation circuit 305 is switched to the auxiliary pulse from the driving pulse. Thus the watch rough torque is measured in correspondence to the pulse duration. The frequencies of the driving and auxiliary pulses can be set freely via circuit 300 with the quick setting mode secured, thus ensuring a quick measurement for the watch rough torque.

Abstract: PURPOSE: To prevent the hunting of a valve body in case of the starting of functioning, by mounting space corresponding to a throttle valve portion at the lower surface side of a throttle valve seat portion of a fixed flow-rate valve.  
     CONSTITUTION: Pressure water passed through each flow path a, b, c and flows out to the secondary pressure side from an outlet flow path. When the flows of the flow path a are narrowed by means of an orifice 7, a resistance portion body 4 is subject to thrust by pressure difference produced on the before-and-behind surfaces and pushed in the flow direction, the direction of a throttle valve seat portion 11, to contract the opening of a throttle valve, and balances with the force of a spring, and prescribed, fixed flow-rate value is kept. If pulling up a correction portion body 16 from a condition that the correction portion body 16 is located at the lowest limit and the flow path is closed, an end edge portion of a throttle valve portion 10 reaches an inlet of valve seat portion 11 lower surface vibration space by forming initial vibration space 18 to the throttle valve seat portion 11, and hunting in the case when starting water passing action is lessened in negligible degree.
