Title: Dimension measuring unit dependent upon optical scanning
Inventor: SHIMIZU MOTOI
IPC: G01B11/02
Filed: 1979-07-09
Abstract: PURPOSE: To simplify a unit by installing a measured object in the parallel light flux obtained by a lens and by rotating a rotary mask having a small hole in the front of the receiving-side lens pupil and by scanning the lens pupil face in an arc to measure the form of the measured object and by converting the measured result to linear dimensions by an operating circuit.  
     CONSTITUTION: The light of monochromatic light source 6 which lights in pulses passes through slit 7 and becomes a parallel light flux by lens 8 and passes through aperture stop 15 having a square aperture and is condensed onto dispersing plate 13 by condenser lens 12 and is led to photoelectric conversion element 14. Measured object 9 is installed in the parallel light flux, and meanwhile, the small hole provided in disc 10 scans the pupil of lens 12 in an arc by rotation of disc 10 connected to synchronous motor 11. As a result, a pulse signal corresponding to the light flux which is not shielded by measured object 9 is output from photoelectric conversion element 14. This pulse signal is converted to a count corresponding to linear scanning by an operating circuit, thus calculating dimensions. Consequently, the unit can be simplified.

Title: Pulse generator for electric discharge machine and its pulse generating method
Inventor: ERUNSUTO BIYUURAA
IPC: B23H1/02
Filed: 1992-03-12
Abstract: PURPOSE: To increase efficiency of a known pulse generator, to reduce dimensions and to reduce manufacturing costs. CONSTITUTION: Pulse current is continuously measured by a current sensor 4 and the measured value is delivered to a control circuit 5. By switch elements 10, 11 and spark-circuit inductance 3, pulse current becomes a target value determined by a system connection 6. At the pulse end, energy existing in spark- circuit inductance 3 is discharged into capacitors 37, 38. From the capacitors 37, 38, energy is recovered to a DC voltage power source 1 or is recovered to spark circuits 2, 3 at the time of the next current pulse. This recovery is made possible by only two switch elements 10, 11. One terminal of the DC voltage power source 1 is common to electrodes of a spark path. By separate switch elements 12, 13, non-load voltage can be controlled.

Abstract: PURPOSE:To remarkably reduce the current consumption of a stand-by state by deciding so that voltage pulled up by this resistor is lower than the source voltage of a peripheral circuit in a semiconductor memory with four transistors two resistors type SRAM cell. CONSTITUTION:As compared to a conventional four transistors two resistors type cell, this memory is provided with two diodes D1, D2 for preventing back flow so that no current flows backward when potential at A, B are higher than the voltage VCCT of the cell. further, instead of the level of the source voltage VCC of a conventional semiconductor, the memory is constituted so as to have the voltage level independent of the VCC as the voltage VCCT. Then, the memory is constituted so that since the voltage generator of the VCCT has a temperature detector, in the case of high temperature where leak current is increased and in the case of low temperature where the resistance of a high resistance poly-silicon film is high, the voltage is outputted respectively, in normal temperature, the voltage is suppressed to low. Thus, the current consumption of the stand-by state is drastically reduced.
