IPC: B23Q15/00
Filed: 1988-06-30
Abstract: PURPOSE:To shorten tool setup operating time and improve the reliability of a correction value by obtaining a first error of an assembled tool to a setting dimensional value and a second error to a required dimensional value for a work set when the work is machined, and modifying-controlling the correction value of the tool using the difference between these errors. CONSTITUTION:A measured error to a setting dimensional value I1 of a cutting part of an assembled tool and a machining error of a work to a required dimensional value H1 set when a trial machining operation is performed are obtained, and the difference between these errors is controlled as a correction value R1 of the tool.

Title: Battery back-up circuit for memory
Inventor: SAKAGAMI SHIGERU
IPC: G05B9/02
Filed: 1988-06-29
Abstract: PURPOSE:To measure the battery voltage in a real load state by switching the memory supply voltage to the battery side just for the time required for measurement of the voltage while a main power supply is working. CONSTITUTION:When the battery voltage Vb is measured, a processor 5 outputs a switch control command SC to a switch circuit 6 while a main power supply is working. The command SC is equal to a high-level signal having a fixed time width. Thus the switch 6 switches a power supply line led to a memory 7 to the side of a battery 3 as long as said high-level signal is supplied. Furthermore the processor 5 issues a voltage measurement command VMC while the power supply line is switched. A battery voltage measuring circuit 4 receives the command VMC and measures the voltage Vb at this time point. Thus the circuit 6 is switched for a fixed time while the power supply is kept ON and therefore the voltage Vb is measured at the real load.

Title: Solid state image sensor
Inventor: TORIYAMA KEIJI
IPC: H04N5/369
Filed: 1989-06-23
Abstract: PURPOSE:To eliminate remaining charge and to prevent generation of an after image by providing a shallowest region of a first conductivity type well of a solid state image sensor having a vertical overflow drain structure shiftingly from the center of a photoelectric converter to a charge transfer unit side to be provided. CONSTITUTION:A P-type well 2 is formed on a N-type semiconductor substrate 1, and a N-type region 3 for forming a photoelectric converter and a N-type region 4 for forming charge transfer means are formed therein. The shallowest part of the well is formed not at the center of the converter but a part near the charge transfer means. Since the part of highest depleting potential of the converter is disposed near the charge transfer unit, the potential of the converter of the region near the charge transfer unit is pulled by a fringe electric field of a reading pulse when a pulse voltage for reading a signal charge is applied to a polysilicon electrode. Thus, all the signal charge can be read to the charge transfer unit, and no remaining charge is generated in the converter.
