Title: Bubble memory
Inventor: UEKI ISAO
IPC: G11C11/14
Filed: 1979-01-16
Abstract: PURPOSE: To omit the special external memory by providing the minor loop with every second bit of the major loop and thus obtaining the mask signal of the defective loop from the bubble memory chip itself.  
     CONSTITUTION: Minor loops m.1Wm.n are distributed at the single side of major loop M-1 and with every second bit. The transfer of the bubble is carried out via replicates R-1WR-n between minor loop m and major loop M-1. When the reading access is given to the bubble memory, the marker of loop M-1 is detected first out of the output of detector DE. And then replicaters R-1WR-n are driven to read out the information of loops m.1Wm.n. If this information shows the defective bit, the reading and writing information are masked. The bubble passed through detector DE reaches eraser AN after a fixed period to be erased for acceptance of the  next information.

Title: Semiconductor-wafer positioning apparatus
Inventor: ISHIHARA AKIRA
IPC: H01L21/68
Filed: 1989-01-11
Abstract: PURPOSE:To achieve the high processing speed of an image signal and to decrease a cost by a constitution wherein luminous flux which is inputted into an image sensing element through a one-way converging optical system, and the slender luminous flux is inputted. CONSTITUTION:Luminous fluxes L1 and L2 from both image sensing regions E1 and E2 are converged in the separating direction B between both image sensing regions E1 and E2 through one set or two sets of one-way converging optical system 5. Slender luminous fluxes L1' and L2' along the perpendicular direction C with respect to the separating direction B are guided into one set or two sets of linear image sensing elements 6 forming a pair. A distance DPP (converted distance on the surface of a semiconductor wafer 1) between the peaks of the image signals of both slender luminous fluxes L1' and L2' which are detected with the linear image sensing elements 6 is computed in a peak-to-peak distance operating means 7. An operating means 8 for the correcting amount of rotation operates the correcting amount of rotation alpha based on the distance DEE between the image sensing regions and the peak-to- peak distance DPP. The result is imparted to a rotation control means 4. The rotation control means 4 controls a wafer rotating means 2. Correcting rotation is performed by the correcting amount of rotation alpha from the position aligned state as a coarse adjustment. Thus, the direction ((x) direction) of one side of an element pattern becomes parallel with a reference direction A, and positioning as a fine adjustment is completed.

IPC: G11B31/00
Filed: 1984-01-17
Abstract: PURPOSE:To cut automatically a CM (commerical) broadcast and to record only the program contents by providing a switch signal transmitter to a VTR and using a remote control signal given from the transmitter to stop temporarily the VTR recording and release this stop mode. CONSTITUTION:The input video signals are applied to a remote control oscillation circuit 6 and a CM-CODE separation circuit 1 via a tuner circuit 7. The circuit 1 separates a CM identification code, and a CM-CODE discriminating circuit 2 discriminates the presence or absence of the CM identification signal. Based on the result of discrimination of the circuit 2, a mode selecting circuit 3 selects a record temporary stop mode and a record mode and applies the stop mode to an REC/PLAY/PAUSE control circuit 4. In another case, the record mode is applied to an REC/PLAY/PAUSE release control circuit 5. Then a control signal for temporary stop is applied to the circuit 6 from the circuit 4, and a control signal for stop release is applied to the circuit 6 from the circuit 5. These control signals are applied to a VTR from the circuit 6. Thus only the program broadcast are automatically recorded.

Title: Stop-protective circuit of voltage type inverter
Inventor: MOCHIZUKI MASATO
IPC: H05B6/06
Filed: 1989-01-12
Abstract: PURPOSE:To prevent generation of overvoltage on the inverter side at the time of stopping large load of inductance by gradually decreasing an output current at the time of stopping a voltage type inverter to perform output cutoff after its value becomes sufficiently smaller. CONSTITUTION:When stop instruction is given to a voltage type inverter 5 in operation, a means 13 lowering current instruction value at prescribed change speed and a means 14 lowering frequency instruction value at prescribed change speed operate, and when a current instruction detection means 21 detects a drop of the current instruction value to prefixed value, output of the voltage type inverter 5 is cutoff. That is, when electromagnetic energy to be stored in inductance of a load 6 is made smaller, overvoltage is not generated so that cutoff is performed after an output current of the voltage type inverter 5 is reduced to smaller value. Thereby, when large load 6 of inductance is made to stop, the voltage type inverter 5 is prevented from generating overvoltage.
