Inventor: UCHIDA YUTAKA
IPC: H01J37/28
Filed: 1992-01-08
Abstract: PURPOSE:To set the pulse cycle period of an electron beam freely without using a photoelectric element by controlling the gate voltage to be applied to an accelerating electrode to selectively accelerate the electron generated in a photoelectronic transfer unit. CONSTITUTION:When the laser beam L of the very high speed pulse train, which is output from a mode-locked laser, is inputted, a photoelectric transfer unit 21 of an electron gun 13 generates the electron e<-> in a pulse train corresponding to the pulse train of the laser light L. Gate voltage V is applied to an accelerating electrode 22, and the gate voltage V is controlled by a control device 25 to selectively accelerate the electron e<-> generated in the photoelectric transfer unit 21. With this structure, a period of the pulse of the electron beam, which is generated in the photoelectric transfer unit 21 and passes through a pin hole 24, is synchronized with the period of the pulse of the laser beam L, which is inputted into the photoelectric transfer unit 21. Consequently, in the case where the measuring signal processing system is not operated at a high speed or a period of a change of the material to be measured is long, the period of the pulse of the electron beam can be set freely in response to it.

Title: Pll lock detection circuit
Inventor: MIZUMAKI HIDETAKA
IPC: H03L7/095
Filed: 1990-01-08
Abstract: PURPOSE:To quickly attain sure lock discrimination in a stable locking state by holding a phase error detection signal for a prescribed time even when it is outputted and outputting a signal synchronously with a VCO. CONSTITUTION:When the phase error detection signal is inputted from a phase comparator means 5, a 1st shifting means 3 outputs an unlock to a 2nd shifting means 4 after the means 3 counts a clock from the VCO by N times and the 2nd shifting means 4 outputs an unlock output immediately in response to the unlock output. However, the 1st shifting means 3 outputs a lock output to the 2nd shifting means 4 immediately when the lock output is received from the phase comparing means after counting the clock from the VCO for N times. That is, when a margin is given to phase error detection and a phase error is detected once, no lock output is outputted immediately even when the phase comparing means 5 detects the locking state. Thus, erroneous locking output in the transient response is prevented.

Abstract: PROBLEM TO BE SOLVED: To reduce the capacitance values of DRAM cells and improve the integration rate of the cells by a method wherein potentials of data written in the cells are elevated. SOLUTION: When a datum in a high level is written in a cell 1, the datum is written with a potential higher than a power supply voltage Vcc by β, i.e., with a potential of Vcc+β, and a voltage of Vcc+β is applied to a node A. When the datum in the cell 1 is read out, the datum can be read out to a bit line BL or a bit line bar-BL when the potential of a word line WL1 is in a high state and stable. Therefore, by the capacitance CS of the capacitor 12 of the cell 1 and the capacitance CB of the BL, the voltage VBL of the BL is elevated to CS/(CS+CB).β and applied to a sensing amplifier 30. With this constitution, the data can be read out in a stable state, the capacitance of the capacitor 12 at a refresh time can be reduced and the integration rate of the cells can be improved.

IPC: H02G5/10
Filed: 1978-01-17
Abstract: PURPOSE: To effectively prevent local overheat due to eddy current, by covering an end portion of a bushing fitting plate with an air channel, and by forcedly cooling the end portion by cooling wind.  
     CONSTITUTION: An air channel 4 is connected in a shape that the channel stretches over a bus box 2 and a side plate 1b of a bushing pocket 1 so as to cover an end portion of a bushing fitting plate 1a of a rest induction electric apparatus (A transformer, etc.). When lead current 10 flows through a lead wire 5, eddy current 11 counter flows to the lead current 10 on the side plate 1b, is shunted by the bushing fitting plate 1a and flows through the interphase portions 1c of the lead wire of the bushing fitting plate 1a. Thus, the local overheat of the interphase portions 1c of the lead wire of the bushing fitting plate 1a can be prevented because cooling wind 12 flowing through a shell 3 flows through the air channel 4 and the portions 1c are forcedly cooled. If the air channel 4 is made of a conductive material, eddy current 11 is shunted to the air channel 4, and the local overheat can further be obviated.
