IPC: G11B27/10
Filed: 1985-12-06
Abstract: PURPOSE:To reproduce data even when a track address and a sector address are inferior by writing the track address and sector address which have the same contents with the track address and sector address which are preformatted during recording operation. CONSTITUTION:The track address and sector address 20 which are preformatted are recorded previously. An independent track address and a sector address 30 having the same contents with to the address 20 are recorded at the same time when a data part 11 is written.

Title: Blade for centrifugal fluid machinery
Inventor: SHIRAISHI KEIICHI
IPC: F02B39/00
Filed: 1995-10-24
Abstract: PROBLEM TO BE SOLVED: To increase outlet pressure without following to rotational speed higher than the case where rotational speed of an impeller is high, and obtain high efficiency in a low and intermediate pressure ratio ranges which rotational speed of the impeller is low by arranging the blade freely to move it in right/left directions by dividing the vicinity of the outlet of a blade into a disk. SOLUTION: In the impeller of a centrifugal compressor, a slit 3 having a prescribed length from an outlet to an upstream side is arranged between the hub side of a blade 2 and a disk 1. Since the blade 2 and the vicinity of the outlet are not fixed to the disk 1, when rotational speed of the impeller is high in a blade having the backward angle (a) of the outlet of the blade 2 during stopping the impeller, centrifugal force acted on the outlet side of the blade 2 is enlarged, the impeller is deformed in a direction in which the backward angle of the outlet of the blade 2 is reduce, and the impeller becomes a backward angle (b).  Namely, In a range whose rotational speed of the centrifugal compressor is high and pressure ratio is high, the backward angle of the impeller is reduced automatically, and discharging pressure of the centrifugal compressor is increased without increasing rotational speed especially.

Title: Refrigerator
Inventor: KURIYAMA TORU
IPC: F25B9/14
Filed: 1988-10-31
Abstract: PURPOSE:To increase the refrigerating capacity and to employ a smaller motor for driving a displacer by providing a speed reducer on the motor to reduce the rotating speed of the motor. CONSTITUTION:A driving unit 41 that drives a displacer 12 consists of a synchronous motor 42 that is operated stepwise, and a speed reducer 43 that transmits the rotation of the motor 42 to a crank shaft 28 after reducing the rotating speed of the motor 42. The employment of the speed reducer 43 causes the motor 42 to rotate smoothly, resulting in a smooth movement of the displacer 12. Especially, a fluctuation in the rotation speed of the motor 42 may not occur even when an instantaneous force is exerted on the displacer 12 because the torque of the motor 42 is amplified by the reducer 43. Therefore, the displacer normally moves smoothly. As a result, a reduction in the sealing performance and a decrease in the cold generating amount can be prevented and a lower temperature operation is realized, so that the refrigerating capacity can be increased and a smaller motor can be used.
