Abstract: PURPOSE:To prevent the concentration of re-applied currents, and to obviate the breakdown of a main thyristor by connecting cathodes in the main thyristor and an auxiliary thyristor by an inductive element and flowing currents from the auxiliary thyristor on the failure of commutation. CONSTITUTION:Cathode electrodes in an auxiliary thyristor 12 and a main thyristor 11 are connected by an inductive element 6 consisting of an element or a substance, an inductance component therein is large. When the life time of carriers at a low current level of the auxiliary thyristor section 12 is made previously larger than that of the main thyristor section 11, commutation fails from the auxiliary thyristor section 12 when applying re-applied voltage, high voltage is applied to the inductance element 6, high currents flow into a gate in the main thyristor 11 through a resistance region 7, and the main thyristor 11 is turned ON. Accordingly, sufficient resistance is obtained even to the large di/dt of re-applied currents 18 in the main thyristor 11.

Abstract: PURPOSE:To accelerate a processing speed in a digital signal processor(DSP) by reducing the number of processings for obtaining the shortest distance of data to N pieces of reference points. CONSTITUTION:For instance, the data (a) stored in a RAM 1 and an (i)-th reference point bi stored in the RAM 2 are respectively transferred through registers 5 and 6 to an ALU 4 and the ALU 4 obtains a-bi. The a-b, are fed back to the register 6 by an SEL 12 and further transferred to one of the input ports of an MPY 3. The MPY 3 multiplies the data a-bi from the register 6 and a-b, from the SEL 13 together and obtains the distance (a-bi)<2> between the reference point and the data (a) and the distance (a-bi)<2> is stored in an accumulator 9. The ALU 4 compares the distance (a-bi)<2> with the shortest distances of the data (a) to first to (i-1)-th reference points stored in the accumulator 10 and the SEL 14 stores the smaller data in the accumulator 10 based on the compared result.

Filed: 1988-01-29
Abstract: PURPOSE:To precisely and simply attain the calibration of a coordinate system by using a coordinate system calibration board where plural recognition patterns which can be identified are drawn on an outer periphery. CONSTITUTION:The coordinate system calibration board 4 where plural recognition patterns which can be identified on the outer periphery is placed on a prescribed work area where calibration is to be executed, and they are image- picked up by an image-pickup device 3.

Title: Fault detecting system of transistor
Inventor: YAMAZAKI NOBUHISA
IPC: H03K17/08
Filed: 1982-02-05
Abstract: PURPOSE:To prevent a circuit from breaking down if a short circuit is formed between an emitter and a collector and an open state is caused between a base and the emitter by monitoring a base potential and stopping voltage supply to the collector in case of a fault. CONSTITUTION:When base potentials of power transistors (TR) are at a level ''H'', currents flow through coils 7 and 8 to drive printing pins. If the power TRs 1 and 2 are short-circuited between emitters and collectors and open between bases and emitters, base potentials rise. At this time, the potential between both terminals of a resistance 11 also rises, so an iut voltage to a voltage comparator 12 exceeds a reference voltage. Therefore, the output of the voltage comparator 12 goes up to the level ''H'' and consequently while a fuse 14 with a contact is burned out, the contact is opened to stop the power supply to the power TRs.

Title: Flow velocity measurement float
Inventor: TAYAMA SEIICHI
IPC: G01P5/18
Filed: 1998-01-29
Abstract: PROBLEM TO BE SOLVED: To provide a flow velocity measurement float which is extinguished without harming the environment in the periphery of rivers in a short time after a flow velocity is completely measured. SOLUTION: A flow velocity measurement float 1 is not deformed until a fixed time passes after the float is thrown in, e.g. a river. A time required for the flow velocity measurement float 1 to flow between two set cross sections is measured from visual confirmation of a mark part 11 by two observers standing at the river bank or the like. A distance between the two cross sections is divided by the time, thereby measuring a flow velocity. When the fixed time passes after the completion of the measurement, a cylindrical part 5, plug parts 7, 9 and the mark part 11 are disassembled, extinguished in water and, a weight 13 packed inside, namely, sand flows out. The flow velocity measurement float 1 is thus extinguished, doing no harm to the environment.
