IPC: H04N1/04
Filed: 1985-06-29
Abstract: PURPOSE:To decrease dark current noises and to improve S/N by dividing a conventional single form photodetector into plural photodetecting stages having a small photodetection area and selecting and adding outputs of the photodetecting stages. CONSTITUTION:The photodetection stages 16a-16n have respectively a photodetecting area smaller than that of a conventional photodetector and the outputs are inputted to an input selecting and adding circuit 26 provided to a control section 25. The circuit 26 is constituted as an analog switch circuit to select or add the inputs inputted from the photodetection stages 16a-16n. A control circuit 27 provided in the control section 25 has a function controlling blinking of each light emitting element of a light emitting section 12 via a drive section 14 and the function has a specific relation with the switching timing of the circuit 26. For example, when reflected lights 28a-28d from an original are made incident on one photodetection stage 16a only, the circuit 26 outputs selectively the output of the photodetection stage 16a only and just before the reflected light is made incident on the photodetection stages 16a, 16b at the same time, the circuit 26 adds switchingly each output of the photodetection stages 16a, 16b.

Abstract: PURPOSE:To increase the information transfer speed between the memory unit and the requested unit, by splitting the memory unit of random access into a plurality of memory modules, and by providing the circuit group corresponding to each module and common sharing circuit group. CONSTITUTION:The request unit 1 continuously delivers two memory access requests and the simultaneous operation disignation signal on the signal line 53.

Abstract: PURPOSE: To prevent the dislodging of the build-up part by fitting dies to both sides of the plural wide-bottomed depressed parts pierced across the fissure erosion part of the steel ingot mold, driving wedges between both dies to fix them then performing build-up welding.  
     CONSTITUTION: Holes 5, 5 are pierced at a required spacing to both sides around the fissure erosion part 2 of a steel ingot mold 1. Next, with the right and left holes 5, 5 as a reference, the depressed parts 6 of continuous form which cross the erosion part 2 and whose right and left groove ends are of wide bottom form are grooved. On the groove bottom of the depressed parts 6, the dies 7, 7 of the same shape as the right and left end shapes of the depressed parts 6 are fitted, thence wedges 8 are driven between the dies 7, 7 to wedge both ends of the dies 7, 7 to both side walls of the grooves of the depressed parts 6. Then, buile-up welding 4 is done on the circumferences of the dies 7, 7, and wedges 8 as well as the erosion part 2 and the surfaces are finished. This method enables the dislodging of the build-up part to be prevented by the wedging parts at both ends of the dies 7, 7 despite the formation of fissures under the weld beads and the withstanding times of the mold to be increased considerably.

Title: Clock crossover circuit
Inventor: HAMADA SHIGERU
IPC: H04L7/00
Filed: 1987-06-09
Abstract: PURPOSE:To preclude the possibility of an error in a readout data even if a write clock has a fluctuation by devising the circuit such that a difference between the count of a write address counter and a readout address counter is always not less than the setting value. CONSTITUTION:A data write means 10 writes a write data in parallel by using a write clock according to the address designation of a built-in write address counter and a multiplex means 11 uses a readout clock so as to multiplex the signal and to output the result according to the address designation of a built-in readout address counter. Moreover, a phase difference detection means 9 restarts the readout address counter from the initial value when a difference between the counts of the write address counter and the readout address counter, that is, a phase difference between a load shift pulse and a strobe pulse reaches a setting value or below thereby making the value not less than the setting value at all times. Thus, the possibility of the readout data in error is reduced even with the presence of fluctuation in the write clock.
