Title: Chopper controller
Inventor: HORIUCHI MICHIMASA
IPC: H02M3/135
Filed: 1978-02-20
Abstract: PURPOSE: To fully utilize the control range of a chopper by providing a means to detect a commutation period and automatically adjusting the time from the "off" condition to next "on" signal is given corresponding to said commutation period.  
     CONSTITUTION: The output interval of a by-pass circuit 7 automatically varies with the variation of a commutation time T o  after an "off" signal S off  is given as most of said commutation time T o  are being detected by a potential detector 4 whereby the next "o" signal S on  is always given after the commutation of the chopper is finished regardless of the motor current level I m . Therefore, the control range of the chopper is not reduced as its maimum utilization time varies corresponding to the motor current.

Abstract: PURPOSE:To reduce the size of an evacuating device and to provide max. performance of a pump in an electron beam welding machine, by constituting the evacuating device of a rotary vacuum pump of variable rotating speeds and driving the same with an electric power source of variable frequencies. CONSTITUTION:The evacuation of a welding chamber 6 is started by means of a rotary oil pump 14 after installation of objects 6 to be welded. The pump 14 is operated at the rated number of revolutions, and the air is evacuated through a Roots pump 10. When the output signal of the 2nd vacuum gage 21 attains the signal quantity or below of a reference signal source 24 on progression of the evacuation, the 1st signal converter 22 and the 1st pump power source 26 operates so that the pump 10 is run at a low speed. The frequency of the power source 26 is increased gradually with a decrease in the pressure of the gage 21 until finally the number of revolutions is maintained at the preset upper limit value. The pump 14 is also operated at an increasing speed with the gage 21, the 2nd reference signal source 25, the 2nd signal converter 23, and the 2nd pump power source 27 of a variable frequency type, but unlike the pump 10, the speed thereof is not reduced and the pump is operated at the speed between the rated value and the preset upper limit value.

IPC: H01L21/027
Filed: 1998-01-30
Abstract: PROBLEM TO BE SOLVED: To select a graphic at high speed, by providing an electrostatic deflec tor for forming deflection and an electrostatic deflector for graphic selection, and matching the deflection centers of them. SOLUTION: Deflection of deflecting deflecting is executed in a center deflector. Thus, forming deflection is executed in the electrostatic defector 6 and deflection for graphic selection is executed in another electrostatic deflector 7. Deflecting formation operates at 20V and at high speed of 50ns. On the other hand, the voltage of 50V is required in graphic selection deflection since a deflection angle is large and deflection time becomes 1μs. The deflection centers of both are matched with the crossover image of a transfer lens 5 on an upper stage, and a crossover position by deflection does not move. In the device, an objective diaphgrams 11 is arranged on the crossover image face of a reduction lens 10.  When the graphic is selected, the axis of an electron beam is returned to an original state by a return deflector 12 on the crossover image face of the transfer lens 5 at a lower stage.

Title: Semiconductor memory device
Inventor: KAMATA MINORU
IPC: G11C11/407
Filed: 1986-01-30
Abstract: PURPOSE:To obtain a semiconductor memory device with a great action margin and a wide action voltage range by permitting a power source voltage detection circuit to switch the delay of a word line boosting circuit having a delay switching circuit. CONSTITUTION:The word line boosting circuit consists of buffers 1 and 2, a boosting capacitor 3, delay circuits 4 and 5 and a switching circuit 6. The buffer 1 is regulated by a boosting start signal phi1, while the circuit 6 is regulated by the signal phi and a power source voltage start signal phi2, and generates a signal phi3 obtained by delaying the signal phi1 through the delay circuits 4 and 5. The buffer 2 is regulated by the signal phi3, and drives the capacitor 3 after being charged. If the power source voltage is high, the signal phi2 is at a level H. At that time, if the signal phi1 changes to a level L from a level H to drive the buffer 1, the charge of the capacitor 3 starts. Simultaneously, if a delay selection circuit selects the circuit 4, the signal at a level H changes the signal phi3 to a level L from a level H through the circuit 4 and a NOR circuit, thereby executing boosting. If the power source voltage is low, boosting is made in the same manner.

The thermal analysis information is obtained when this output is recorded, and the light absorption characteristic of the sample 1 is measured by a light source 8 and a spectrophotometer 9. The S/N ratio of thermal analysis measurement can be satisfactorily secured when the temperature of the sample 1 is detected by thermocouples 4a-4f and their outputs are added by an adding circuit 10 to improve the S/N ratio and a light passing hole 33 is provided on the sample mount section of a thermosensitive plate 3 to measure the thermal analysis and light absorption characteristic concurrently, for example.

IPC: H04M9/00
Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To simplify a video intercom system. SOLUTION: When a hand set signal from a cameraless entrance hand set 2 is inputted to the CPU of controller 3, a DC signal S4 is outputted from a signal sending circuit 7 to a common line H and when a hand set signal from an entrance hand set 1 with camera is inputted to the CPU, a pulse signal S5 is outputted from the signal sending circuit 7 to the common line H for a fixed period while being superimposed on the DC signal S4. The pulse signal $5 is fetched into a base unit 5 with monitor connected to the common line H, held by a hold circuit 31 and plotted on a monitor 33. When a hand set 8 is hooked up at a base unit 5 with monitor or a base unit 6 with no monitor connected to the common line H, a hook-up/down signal is outputted and the level of DC signal S4 is reduced.  This reduction is detected by a detection circuit 30 and since it is enough to detect two levels at the detection circuit 30, the system is simplified.

Title: Voltage-controlled oscillator
Inventor: MAKIMOTO MITSUO
IPC: H03C3/00
Filed: 1982-02-09
Abstract: PURPOSE:To adjust modulation sensitivity independently and to improve noise characteristics by providing a varactor diode for modulation where element sensitivity is low in a PLL type oscillator. CONSTITUTION:In a common collector oscillating circuit, a control voltage from the PLL circuit is supplied through a terminal 38 to a varactor diode 34 connected to a base terminal. An FM-modulated signal from a terminal 39 is supplied to a varactor diode 36 connected to a collector side. Then, the Q value of a base-side resonating circuit decreases by as much as only one varactor diode 34, so the C(carrier)/N ratio of an oscillation output signal is held high. Further, the collector-side varactor diode 36 has low sensitivity, so the modulation sensitivity is decreased easily in its design stage.
