Title: Signal amplifier circuit and signal amplifying method
Inventor: NAGANAMI TORU
IPC: H03K5/02
Filed: 1998-10-08
Abstract: PROBLEM TO BE SOLVED: To provide a signal amplifier circuit whose consumption current is small and which is also fast drivable even if a DC current is increased to accelerate a response speed of a differential amplifier circuit and to provide a signal amplifying method. SOLUTION: A differential amplifier circuit is formed by using a current mirror circuit. The difference between a signal inputted to the differential amplifier circuit and a reference voltage is amplified by another differential amplifier circuit and is inputted. When the output of the former differential amplifier circuit is made a high level, a differential amplifier circuit driving a P channel MOS transistor 101 for driving the next stage and a differential amplifier circuit driving an N channel MOS transistor 103 are separately formed by causing large current to flow to the current mirror circuit by such a manner that current flowing through one path in the current mirror circuit is caused to temporarily flow to a branch path. Thus, it is possible to obtain a signal amplifier circuit whose consumption current is small and which is also fast drivable.

Filed: 1990-10-26
Abstract: PURPOSE:To prevent thermal fatigue generation caused by the temperature fluctuation at the part mixing with pumping liquid by providing a heater in a high temperature pump to heat low temperature seal purge liquid using the high temperature pumping liquid as a heat source. CONSTITUTION:A seal purge path D surrounded by a heater 20 and a journal 11 is usually filled with high temperature pumping liquid B and the fluid in the space D is given an azimuthal velocity component Vtheta by the effect of the journal 11 rotating together with vanes 3. Due to the existence of the azimuthal velocity component Vtheta, a dynamic pressure difference  Ps in the radial direction is produced in the fluid. Resultantly, the pumping liquid B is circulated in the path 23 by the pressure difference  Ps. A necessary heat transfer area is provided to the path 23 to heat the low temperature seal purge liquid to a necessary temperature. Thus, the low temperature seal purge liquid A exchanges heat with the pumping liquid B to be heated during flowing down in the gap E between the main body 21 of the heater 20 and a main shaft 4.

Abstract: PURPOSE:To adjust the clearance between an upper and lower rotary knives by supply ing a cooling medium into the cooling hole provided to the knife shafts to which rotary knives are attached, by detecting the difference between the temperature of each of the knife shafts, and by controlling the temperature of the knife shafts so that the temperature difference may become beneath the specified value. CONSTITUTION:The temperature of bearings 5 and 6 which causes the temperature rising of an upper and lower knife shaft 4RU and 4RD is detected by a temperature sensor 11, and the difference between the temperature of each of the knife shafts is calculated by a detecting device 12. When the temperature difference becomes specified value or more, it is transmitted to a cooling pattern decision sequence 13 together with operation command. The sequence 13 sends the command for flowing the volume of cooling water corresponding to temperature differences to a flow control valve 14 and controls the opening degree of the valve for adjusting the volume of water flow. Then, cooling water is made to flow in bearing chocks or the knife shafts 4RU and 4RD to cool the bearings 5 and 6 for controlling the temperature of a knife shaft 4. This serves to keep knife clearance always constant for conducting excellent trimming.

Title: Pin cushion correction circuit
Inventor: SUZUKI SOUHEI
IPC: H04N3/227
Filed: 1988-11-15
Abstract: PURPOSE:To eliminate horizontal vibration of screen without losing horizontal pin cushion distortion correction by connecting a voltage limit element between an output terminal and ground of a circuit generating a parabolic modulation signal. CONSTITUTION:A constant voltage diode 1 being a voltage limit element is connected between an output terminal (a) and ground of the circuit generating a parabolic modulation signal for horizontal pin cushion correction. When a voltage of the constant voltage diode 1 is set to a proper value, the limiter effect is acted in a range in excess of the limit voltage to limit the voltage difference of the parabolic modulation signal corresponding to the scanning difference between fields at the pattern start. Thus, the parabolic modulation signal is made constant and regular for each field. Thus, the screen vibration in the horizontal direction is prevented while the horizontal pin cushion distortion is corrected.
