Title: Pulse input processor for electric railcar controller
Inventor: AKIYAMA SACHIKO
IPC: B60L3/08
Filed: 1993-05-24
Abstract: PURPOSE:To accurately read the latest data and to use the data for control by sending a latch signal from a latch circuit to a register only while there is a signal impossible to be read, and applying a read command from a weight timing circuit to the register while there is no signal impossible to be read. CONSTITUTION:A latch circuit outputs a latch signal TH to registers 5, 6 according to a latch signal RCK in the case of a read signal 'H'. A weight timing circuit 8 outputs a read command (RD) when a read disable signal (XT) is 'L' of a read disable signal circuit 10 to the registers 5, 6 to a READ signal from a CPU 11. Thus, data in the registers 5, 6 become unstable, the XT is formed in a period not to read data. When data read READ is input during the XT, a weight is applied to the RD until the XT is interrupted, and data is read after the XT is interrupted, and hence the data can be effectively read after it is updated.

Filed: 1978-10-03
Abstract: PURPOSE:To improve bonding efficiency, by inserting a waveform detector element into a transmitter side input terminal of a supersonic wedge, and detecting a wire cut by the waveform detected at the time of bonding. CONSTITUTION:By using support 1, supersonic horn 3 screwed with a supersonic wedge 6 on its end is supported on one side, and oscillator 2 is supported on the other side. Next, oscillator 2 is connected with transmitter 4, and synchroscope 5 is connected to the wiring connecting these elements. When supersonic wire bonding is operated under this structure, the monitor waveform appearing on synchroscope 5 differs between a normal and an abnormal case. Hence, this is converted into a binary digital waveform, and by observing this, a wire cut is ascertained. In this way, a wire-cut detector device is fitted to a bonder device itself.

IPC: H01F27/24
Filed: 1993-05-24
Abstract: PURPOSE:To provide a small stabilizer with stable characteristics even when a plurality of coils are incorporated in accordance with a plurality of discharge lamp. CONSTITUTION:A core 11 has a side-leg core 12, a center-leg core 13, an end core 14, and a middle core 15. The center-leg core 13 has an air gap 16 for leakage flux. The core 11 has coil storing parts 17 for storing coils in a way that the magnetic flux generated from each coil increases mutually. Since the coils are mounted on the same core 11, the electric characteristics are stable even under an effect of magnetic interaction. In this constitution, the magnetic flux in each coil is increased mutually so that each coil requires fewer numbers of turns than a coil with a single-core structure. Since the flux of coils is cancelled mutually in each direction at the middle core 15 put among the coils, the cross suction of the middle cores 15 can be reduced.
