Title: High-gain mos inversional amplifier
Inventor: IWADE SHUHEI
IPC: H03F3/34
Filed: 1984-09-11
Abstract: PURPOSE:To obtain an inversional amplifier in which the gain is extensively enlarged, by forming the amplifier by using three enhancement type FETs and three depression type FETs. CONSTITUTION:When the electric potential at a connecting point 5 rises, an action which increases the electric current of an FETD2 and another action which decreases the electric current simultaneously take place and the FETD2 supplies a constant electric current to another FETE2 irrespectively of the electric potential at the connecting point 5. When the electric potential at an input terminal 2 drops and the electric potential at an output terminal 3 rises under this condition, an action which decreases the drain current of an FETD1 and another action which increases the drain current simultaneously take place. As a result, the electric current flowing to the FETD1 becomes almost constant and the FETD1 becomes a load having a very high resistance component. Therefore, an inversional amplifier in which the gain is extensively enlarged can be obtained.

Thus, collective processing object sources are easily and efficiently extracted and managed/operated.
Patent JP-S6436309-A (JP)
Title: Pressure counter-weight
Inventor: TAKANO NOBUYOSHI
IPC: G05D16/04
Filed: 1987-07-31
Abstract: PURPOSE:To enable a device to be operated even with quite a few amount of differential pressure, by holding the difference or the ratio of pressure by emitting a few amount of gas A from a first small hole and gas B from a second small hole in a section where the first and second holes are closed by a needle. CONSTITUTION:A gas quantity that flows from a space between the outer wall of the needle 20 and the inner wall of an outer cylinder 10 which constitutes accumulators 24 and 25 to bleed-off ports (small holes) 15 and 16 is set inversely proportional to a distance between the front end of the needle 20 and the bleed-off ports 15 and 16. When the pressure in either accumulator 24 (25) is increased a little, the needle 20 is pressed to another side 25 (24), then, the gas quantity in the bleed-off is increased, and the pressure is decreased, thereby, the needle 20 is returned to its original position. A bleed-off quantity can be enough to be set at the 1% of a quantity to be consumed outside a pressure counter-weight at the time of balancing the pressure. Also, when the pressure on either side is increased abnormally, since the needle 20 approaches to the bleed-off port 15 (16), the bleed-off quantity is increased quickly, then the pressure drops, and simultaneously, since the accumulator 25 (24) is sealed from another side completely, the needle 20 is returned to its original position quickly, then, balancing is recovered. In such a way, it is possible to keep the balancing of the pressure even when micro abnormal differential pressure is generated.

Abstract: PROBLEM TO BE SOLVED: To provide a control method of an induction motor by which overexcitation can be avoided and the motor can be accelerated efficiently and smoothly even if the revolution of the motor is low or the motor is operated with no load. SOLUTION: The rated angular velocity 9-6 of an induction motor is obtained in accordance with a rated frequency 9-1, a sampling time 9-3 for calculation and the number 9-5 of data in a table for producing a 3-phase sine wave. Angular acceleration (angular deceleration) 9-9 is calculated from the rated angular velocity 9-6 and an acceleration time (deceleration time) 9-7. Further, the angular acceleration (angular deceleration) is accumulated every sampling time to obtain a transient angular velocity ωtrn. The transient angular velocity ωtrn is compared with a rated angular velocity ωdef.  If the transient angular velocity ωtrn is smaller (larger) than the rated angular velocity ωdef, the induction motor is accelerated (decelerated) by using the transient angular velocity ωtrn and, when the transient angular velocity ωtrn becomes larger (smaller) than the rated angular velocity ωdef, the induction motor is put into a steady state operation by using the rated angular velocity ωdef.

Title: Radio equipment
Inventor: FUKUCHI SATOSHI
IPC: H04B17/00
Filed: 1990-07-23
Abstract: PURPOSE:To easily check the operations of a reception system by providing a means by which a VCO which oscillates a transmission frequency independently from a synthesizer circuit incorporating a VCO for oscillating a reception local frequency in a receiving status can oscillate a reception frequency. CONSTITUTION:When a receiver operation confirming switch S2 is operated, a switch S2-1 is connected to a power source and a voltage is applied across a transmission VCO 1 and sweeping signal oscillator 9. Then the oscillator 9 oscillates triangle or saw-tooth waves which are supplied to the oscillation frequency controlling terminal of the VCO 1 connected by means of a switch S2-2 and the oscillation frequency of the VCO 1 is changed with the lapse of time in accordance with the amplitude of the triangle or saw-tooth waves. Signals oscillated from the VCO 1 are inputted to a high-frequency section 5 by the crosstalk in this radio equipment and a pulsative reception electric field output can be outputted when the oscillation frequency coincides with a waiting frequency. Therefore, when the presence/absence of the pulse in the reception electric field output is confirming after pressing the switch S2, whether the operation of a receiving system is normal or not can be confirmed.
