Title: Inverter malfunction detector circuit
Inventor: INAGI SATORU
IPC: H02H7/122
Filed: 1979-07-23
Abstract: PURPOSE:To accelerate the detection of a malfunction such as commutation failure or the like and contrive the reduction in size of a bridge inverter by detecting the voltages of the respetive thyristors in the bridge inverter with a diode bridge and a photocoupler. CONSTITUTION:Capacitors C1, C2, thyristors SCR1, SCR2, commutation reactors L1, L2 are connected to a battery power supply E to form a bridge inverter. The respective thyristor voltages of the bridge inverter are detected through the diodes bridges D1-D4, D5-D8, and the outputs of the respective bridges are applied to photocouplers PC1, PC2 respectively. When the inverter operates normally, two thyristors may not simultaneously become ON. Accordingly, this state is detected by the photocouplers PC1, PC2 to detect the commutation failure. According to said system, since it can utilize the insulation of the photocoupler, the system can be reduced in size.

Title: Peripheral equipment for programmable controller and operation mode switch method
Inventor: YAMAMOTO JUNJI
IPC: G05B7/02
Filed: 1997-04-11
Abstract: PROBLEM TO BE SOLVED: To easily change a mode to a remote operation mode even if the return of an operation change-over switch is forgotten and the mode is left in a proximity operation mode as it is by resetting the stored present operation mode, and setting the operation mode after resetting the mode to the remote operation mode. SOLUTION: The operation unit of a peripheral equipment 2 repetitively changes the operation mode only when ON output of the operation mode change- over switch 21 is executed. Namely, the operation unit in the peripheral equipment 2 always operates as the remote operation mode since it is reset when power is supplied or when the resetting of the peripheral equipment 2 is released. Even if the switching of the operation mode is forgotten, the unit is started as the remote operation mode after starting and a user can easily use a system incorporated in a programmable controller as the remote operation mode. Consequently, a trouble with the forgetting of the switching of the operation mode change-over switch 21 can be dissolved.

Filed: 1979-07-23
Abstract: PURPOSE: To enable the sticking of spatter on a shielding gas nozzle to be detected by providing a gas outflow hole for detection to the tip of the shielding gas nozzle releasing shielding gas for shading of weld zone.  
     CONSTITUTION: A detecting gas outflow hole 13a is provided to the tip of a shielding nozzle 1 and electric current is supplied from an electric power source 11 to a filler core 6 via a contact tip 2 so that the base materials 7 to be welded are continuously welded by the arc 8 between them and the core. At this time the detecting gas 14 which is reduced of pressure by a pressure reducer 20 and is controlled of flow by a flow regulating valve 18 is flowed from a cylinder. It is desirable to make the flow rate thereof small to be extent of not disturbing the flow of the shielding gas 4. This gas 14 spouts from the effluent hole 13a at the end of a conduit via a solenoid valve 17, a pressure detector 16, etc. In a state where there is no spatter deposit, the detector 16 does not operate. When the hole 13a chokes on sticking of spatter 12a, the gas 14 flow becomes zero or extremely slight and the pressure in the conduit 13 and hose 15 rises approximately to a preset pressure. This causes the detector 16 to operate, thereby stopping the current supply or emitting an alarm.

Filed: 1979-07-24
Abstract: PURPOSE: To reduce the mental burden upon a helmsman, by using the difference in the pitch of a sound or the period of an intermittent sound in addition to visual indication to inform the turning direction and its velocity of ship.  
     CONSTITUTION: A ship's turning angle transmitted from a gyroscope 1 is applied to a signal converter 2 so that the angle is changed into a digital signal. This digital signal is applied to a calculator 3 to compute the angular velocity and pick out the rotating direction of the ship and the magnitude of the angular velocity in the form of digital codes.These digital codes are applied to a display section according to an instruction so tht the codes are indicated and entered into a low frequency generation unit 5. This unit produces a low-frequency intermittent output signal which has low frequency showing the turning direction of the ship and an intermission period showing the magnitude of the angular velocity of turning. The output signal drives a sound generator 6. The pitch of a sound is changed depending on the turning direction. The period of an intermittent sound is altered depending on the magnitude of the angular velocity of the turning. Since a helmsman can obtain information of the ship's turning from the sound while watching forward, the mental burden upon the helmsman can be reduced.
