Title: Power control method and operating device for inverter
Inventor: EGUCHI YOSHIO
IPC: H02M7/493
Filed: 1989-03-09
Abstract: PURPOSE:To prevent counterflow of power from AC side to an inverter by detecting counterflow of power from AC side to DC side of the inverter through a power detecting means arranged at the output side of the inverter then controlling the output frequency of the inverter based on the detected value. CONSTITUTION:An inverter 1 inverts DC power into AC power which is then subjected to voltage conversion and fed to a load. Output from a transformer 19 is fed to a control circuit 2 and inverted DC power is fed to a voltage control circuit 210. Difference between the output from a reactive power detector 20 and a Q command of a reactive power command value 22 is amplified and added. Then forward power is detected from the outputs of an effective power detector 21 through a voltage converter 28, where the inclination of the output value from the voltage converter 28 is set to be equal to the frequency variation of the inverter 1 corresponding to the variation of a frequency command 29.

Title: Method for recovering ammonia water
Inventor: OBATA KASHU
IPC: C02F1/28
Filed: 1999-03-04
Abstract: PROBLEM TO BE SOLVED: To recycle ammonia by a method in which RCA cleaning drainage containing ammonia and hydrogen peroxide, after being contacted with active carbon or a platinum catalyst to decompose the hydrogen peroxide, is passed through a reverse osmosis membrane. SOLUTION: RCA cleaning drainage containing ammonia and hydrogen peroxide is treated with active carbon or a platinum catalyst to decompose/remove the hydrogen peroxide. A method in which the drainage is passed through a contact column filled with active carbon and others is simple and efficient. The content of hydrogen peroxide is preferably about 1.0 ppm or below. Water after the treatment, after being subjected to ion exchange treatment using an NH4-replaced cation exchange resin to remove heavy metal ions, is passed through a reverse osmosis membrane. In this way, the load of the membrane is reduced, impurities can be removed safely without causing a phase change, and ammonia can be recycled.

Abstract: PROBLEM TO BE SOLVED: To make it possible to remarkably reduce the power consumption due to generation of heat of a heater, by controlling the ON/OFF of the heater based on temp. information sensed by a temp. sensor. SOLUTION: When a power switch 1 is turned on, the temp. sensor connected to a liquid crystal display part 3 senses the surrounding temp. of the liquid crystal display part 3 to send it to a microcomputer 2 as a signal. The microcomputer 2 controls the ON/OFF of the heater 4 with a switch connected to the liquid crystal display part 3, and operates efficiently the heater 4 with the switch to make the surrounding temp. of the liquid crystal display part 3 become within the range of an operation warranty temp. of a liquid crystal display element (LCD) by intermittently warming. Further, since the power consumption in a battery is saved by the intermittent operation of the heater 4 with the switch, the power consumption as a whole electronic equipment can be saved, too.

Abstract: PURPOSE:To contrive improvement in power transfer characteristics by a method wherein a power supply part and a power receiving part are positioned in close vicinity or they are contacted with each other, and a closed magnetic circuit in which the first and the second cores penetrate the primary and the secondary windings is formed. CONSTITUTION:An inserting part 8 is constituted on one of the opposing terminals 2a and 6a of the first core 2 and the second core 6, and in order to constitute its receiving part 9 on the other opposing terminal, the inserting part 8 is inserted into the receiving part 9 when a closed magnetic circuit is formed by the first core 2 and the second core 6, as the opposing surfaces of the first core 2 and the second core 6 on the inserting part 8 and the receiving part 9 are widened three dimensionally, their opposing area can be enlarged. Accordingly, the opposing area can be made larger without specially constituting the opposing terminals 2a and 6a of the first core 2 and the second core 6 larger than the other parts of the first core 2 and the second core 6. Even when a gap is generated between the first core 2 and the second core 6, the magnetic reluctance generated by the gap can be made small sufficiently, and the magnetic reluctance as the entire closed magnetic circuit can also be made small. As a result, the characteristics of power transfer can be improved.

Title: Magnetic disk device
Inventor: ISHIMATSU NORIAKI
IPC: G11B23/00
Filed: 1990-03-09
Abstract: PURPOSE:To absorb the reduction of a gap caused by the change of temperature with the aid of an elastic body and to prevent the position of a disk from being deviated by providing the elastic body whose linear expansion coefficient is small between the surface of the inside diameter side of the magnetic disk and the surface of the outside diameter side of a hub. CONSTITUTION:The elastic body 7 is fitted between the surface of the inside diameter side of the magnetic disk 1 and the surface of the outside diameter side of the hub 22 and the linear expansion coefficient of the elastic body 7 is set to be smaller than those of the disk 1 and the hub 22. In the case that the inside temperature of the disk 1 or the ambient temperature is changed, the gap between the disk 1 and the hub 22 is reduced by expansion or contraction caused by the difference of the linear expansion coefficient between the disk 1 and the hub 22. Then, since the linear expansion coefficient of the elastic body 7 is smaller than those of the disk 1 and the hub 22, the reduced quantity of the gap is absorbed by elastic deformation. Thus, even when the temperature is changed, the loading position of the disk not deviated and off-track quantity does not exists. As the result, the reliability of a magnetic disk device is improved.
