Title: Multi-cpu system
Inventor: SHINOZAKI YUTAKA
IPC: G06F15/177
Filed: 1988-02-18
Abstract: PURPOSE:To obtain a multi-CPU system that can secure a satisfactory distance between CPUs by transferring serial data between the CPUs. CONSTITUTION:A data collecting CPU 3 outputs a control signal to a selection means 2 for selection of a CPU 1a, for example, among those CPU 1a-1c, etc., for monitor and control of each device. Thus necessary data are transmitted to and received from the CPU 1a. Then the CPU 3 sends the control signal to the means 2 again for selection of the next CPU 1b, for example, and performs the transfer of data to the CPU 1b. Such actions are repeated so that the transfer of data is possible with use of the serial signal in a multi-CPU system. As a result, any bus is not required for connection between the CPUs and each function block can be freely set.

IPC: B23K26/00
Filed: 1995-02-22
Abstract: PURPOSE: To improve welding accuracy without lowering welding speed by carrying out a welding by controlling the defocus quantity and the output value of a laser beam calculated and stored in accordance with the gap value of the abutting part of a welding member based on the stored quantity. CONSTITUTION: A gap sensor 2 is transferred to one end of the abutting part 7A, 7B 8 of materials 6A, 6B to be welded; and measurement is started for detecting a gap value W. The gap value W at each measuring point is inputted in a welding control unit 1 consisting of microcomputers, with the defocus quantity and the output value of the laser beam calculated and stored in the control memory. The gap sensor 2 is released outside the working area, transferring the welding laser beam 5 of a welding robot 4 to one end of the abutting part, starting welding with a laser generator 3 turned on.  If the gap value W is a reference value or less, the welding is performed with the defocus quantity and the output value of the laser beam as set; if the gap value W is larger than the reference value, the welding is controlled with the values larger than the set value; thereby improving the accuracy and the production efficiency.

Title: Automatic-reset circuit breaker
Inventor: HAMAOKA TERUO
IPC: H01H77/02
Filed: 1997-02-18
Abstract: PROBLEM TO BE SOLVED: To permanently cut off a cut-off breaker if it is once operated for automatic resetting to find that a power system is abnormal, to enable remote control to remove this permanent cut-off and to automatically reset the permanent cut-off once the power system returns to a normal state. SOLUTION: A timer circuit 14 is actuated when receiving from a circuit breaker 11 a signal indicating the detection of a broken state. After a predetermined length of time has elapsed, an instantaneous current flows in the solenoid 13a of a circuit breaker driving circuit 13, driving an armature 13b and allowing the circuit breaker 11 to be reset automatically. A counter circuit 16 performs counting action for a predetermined time in response to a signal from the timer circuit 14, and if the circuit is broken within that time, a power system is determined to have failed, and the timer circuit 14 is locked to permanently break the circuit. If a ground signal is received at the reset input terminal 15f of a permanently cut-off circuit 15 through remote control during the permanent breaking, the timer circuit 14 is unlocked to cancel the permanent breaking.

Title: Decoder
Inventor: SATO YOSHIO
IPC: H03M13/00
Filed: 1988-02-17
Abstract: PURPOSE:To suppress the effect of noise caused due to incorrectable error by limiting an amplitude of a decoded voice when an error rate of a transmission line is high and limiting he band to a low frequency band with a comparatively large voice power. CONSTITUTION:A frame synchronizing detection section 4 acquires a frame timing from a voice data inputted from an input terminal 1. An error correction section 2 corrects an error or a voice data inputted from the input terminal 1 for each frame, and a decoder 3 decodes the voice data subject to error correction to output a voice signal. An error rate measuring section 6 measures the error rate of the transmission line from a frame synchronizing bit of the voice data inputted from the input terminal 1 to control a variable amplitude limiter 7. The variable amplitude limiter 7, when the error rate of the transmission line is lower than a prescribed value, outputs the decoded voice outputted from the decoder 3 as it is to the output terminal 10 and limits the amplitude of the decoded voice outputted from the decoder 3 when the error rate is higher than a prescribed value and outputs the result to an output terminal 10.

CONSTITUTION:Whether or not a correct connection of line is performed is identified from a current vector flowing through a first current detecting coil 3-1 connected to one end of a main winding 4-1 and a second detecting coil 3-2 connected to one terminal of a capacitor 4-4 and then this condition is displayed by an operation displaying lamp. That is, in case that an accurate connection is performed in view of a sum of vector of a current flowing in the first current sensing coil 3-1 passing through the main winding 4-1 and another current flowing in a second current sensing coil 3-2 passing through an auxiliary winding 4-3 and a capacitor 4-4, its sum does not become zero so that an operation displaying circuit 3-3 shows an induced voltage with an operation of the ventilation fan displayed. In case of an erroneous connection of line, the sum of the above vectors becomes zero and the operation displaying circuit 3-3 does not induce any voltage, so that the operation is not displayed.
