Title: Image pickup device
Inventor: SUYAMA MOTOHIRO
IPC: H04N5/225
Filed: 1992-04-30
Abstract: PURPOSE:To perform a shuttering operation at a low voltage by making photoelectrons emitted in the gate period of a low potential change incident on an energy filter while maintaining energy different from that of the photoelectrons in other periods. CONSTITUTION:In a gate period TG whose gate voltage VG is a negative voltage lower than 10.005kV, the energy of the emitted photoelectron is larger than the electric field energy of an energy filter 9, the photoelectron transmits a first and a second mesh electrodes 91 and 92 and is incident on an MCP 4. The emitted photoelectrons except the period TG do not reach the MCP 4 since the energy is less than the electric field energy of the filter 9. Then, a shutter can be released at the voltage VG of the low amplitude of only 10V while maintaining the high voltage of approximately 2kV between an photoelectric surface 2 and a grid electrode 5 for acceleration. Thus, high quality images can be obtained, the operation is accelerated and the generating circuit of the voltage VG is simplified, as well.

Title: Method and apparatus for measuring revolutions of machine
Inventor: DEIITAA HAUKU
IPC: G01R23/10
Filed: 1989-05-02
Abstract: PURPOSE: To enhance the accuracy in measurement when the r.p.m. is high by making a computer interrupt in program and read count after a time interval derived from one tachometer pulse. CONSTITUTION: Tachometer signals A, B are fed to a circuit 4 having an output end 5 for delivering a signal indicative of the rotational direction and an output end 6 for delivering a pulse upon changing the rotational direction. When the signal indicative of the rotational direction is being delivered to the data input end of a computer 3, a pulse at the output end 6 causes program interruption. The r.p.m. is measured by counting the reference signal alternately through counters 8, 9 during the interval between two pulses delivered from a frequency division circuit 17. Upon finishing the counting operation, program interruption takes place and the computer 3 reads out the count through a data bus 10.  Since the other counter has been started during that interval, duration of each period is measured for the output signal for circuit 17 and the measurement is expressed in terms of r.p.m. by the computer 3.
