Title: Power source voltage fluctuation detecting circuit by dual gate cmos circuit
Inventor: SUZUKI MITSURU
IPC: G05F1/56
Filed: 1988-01-08
Abstract: PURPOSE:To know the fluctuation of a power source voltage by providing a constant voltage power source circuit, which keeps the voltage of a second gate of a dual gate to be constant with using a CMOS circuit to use a dual gate FET, the dividing circuit of input voltage to be given to the CMOS circuit and a Schmitt trigger in an output step. CONSTITUTION:Threshold voltage Vth of the CMOS circuit is equal to voltage VG of the cross point of a resistance RDS between D-S of FETs 11 and 12. When there is not a second gate 9 of the FET, the cross point, namely, Vth' goes to be about 1/2 Vdd. On the other hand, the gate voltage VGS is determined by resistances R1 and R2 and since the relative position of the Vth' and VGS is not changed, an output 13 is not changed. When Zener voltage VZ is given to the second gate 9 of the FET11, a RDSn of the FET11 goes to be parallel of the resistances and Vthnot equal to VDD/2 is obtained. With utilizing of this characteristic, when the size relation of the VG and Vth to be inputted to the respective first gates of the FETs is suitably set with being matched to the change of the VDD which is desired to be detected, the relative position of the Vth and VG is changed according to the change of the VDD to be detected and the output 13 is also changed. Then, waveform shaping is executed by a Schmitt trigger buffer 12.

Title: Semiconductor amplifier
Inventor: IKEDA YUKIO
IPC: H03H11/28
Filed: 1992-01-10
Abstract: PURPOSE:To provide the semiconductor amplifier where impedance matching in a fundamental wave is performed in a wide band by performing impedance matching in the fundamental wave by a phase adjusting circuit. CONSTITUTION:When the line length of a front end short-circuit line 7 is 1/4 wavelength in a double wave, it does not have an influence upon the double wave but has 1/8 wavelength for the fundamental wave and functions as an inductance. At this time, the sum of length of connection lines 5 and 6 is 1/8 to 1/4 wavelength in the fundamental wave and is more shortened. Since the output impedance in the fundamental wave of an FET 3 is capacitive, the line 7 is operated to not only reduce the capacity component of the impedance in the fundamental wave but also increase the resistance component and functions as an impedance matching element of the fundamental wave. Consequently, impedance matching in the fundamental wave is performed in a wide band because impedance matching for the fundamental wave is possible even in the place where phase rotation in the fundamental wave is small. The impedance matching is adjusted furthermore by a fundamental wave impedance matching circuit 11 to realize complete wide-band matching.

Title: Method of discharging rod-like piece
Inventor: MURAMATSU TAKESHI
IPC: B65G45/14
Filed: 1979-01-17
Abstract: PURPOSE: To easily discharge a rod-like piece located between belts, by moving up the rod-like piece by a nipping belt conveyor and then using a foamed rubber mat to push up other pieces remaining at a rising section.  
     CONSTITUTION: A conveyor for moving up rod-like pieces 40 such as cigarettes or filter rods consists of the first conveyor 11 and the second conveyor 14. The rod- like pieces 40 are conveyed up while they are nipped between the belts of both the conveyors. When no rod-like piece is conveyed in from the first conveying face 11-1 at the end of conveyance, rod-like pieces 40 are not elevated and remain between both the conveyors. To prevent the rod-like pieces from remaining between the conveyors, a discharging member 31 made of foamed rubber is pushed in and the rod- like pieces are pushed out toward another conveying face 11-3 by a wedge-like end 32. This results in easily discharging the rod-like pieces without leaving them between the belts.
