Abstract: PURPOSE: To bias the rotating shaft and prevent vibration by providing a plurality of grooves in circumferential direction through small intervals at the inside periphery sliding face of a bearing such that the circumferential length of one groove is different from the circumferential length of other grooves, and that the circumferential pitches between the centers of several grooves are different. CONSTITUTION: Grooves 21 and 22 are provided in circumferential direction, through the inside periphery sliding face 23 at a small interval, at the inside periphery sliding face 20 of a bearing 10. The circumferential length of the grooves 21 and 22 made to be different, and besides the groove 22 on the side of the downstream in the rotational direction of the rotary shaft 13 is made long. When the rotary shaft 13 is rotated in the direction of an arrow, lubricant oozes out from the inside periphery sliding face of the bearing 10 consisting of sintered oil containing material, and an oil film is made within the bearing 10. Peak pressure (dynamic pressure) is generated at the steps 21a and 22a on the downstream side in rotational direction of the rotating shaft 13, and the pressure of the oil film works in radial direction of the rotating shaft 13.  By the sum of the vectors of the pressure of these oil films, the rotating shaft 13 is biased to the side of the inside periphery sliding face 23. The vibration of the rotary shaft can be prevented.

IPC: G11B7/085
Filed: 1994-09-30
Abstract: PURPOSE: To obtain an exact offset amount in a short time by detecting a driving signal for an actuator on an arbitrary position and storing the detected driving signal as an offset amount acted on the actuator. CONSTITUTION: A processor part 43 moves a carriage to the intermediate position within a moving range and locks it while monitoring a position signal from a carriage position sensor obtained through an AGC circuit 31.

IPC: G01S7/52
Filed: 1983-12-14
Abstract: PURPOSE:To enable detection in high reliability by preventing a signal based on an interference wave from mixing in a display image, by detecting the generation period of the interference wave preliminarily present in water to determine a transmission period. CONSTITUTION:A correlation means 15 applies correlation to a receiving signal corresponding to two continuous periods in a period when transmission operation is stopped corresponding to two periods of a preset period. Measuring means 16, 17 measure the max. time width in outputs of the means 15 and an addition means 5 adds the outputs of the means 16, 17 to the preset period as correction amount. Because the means 18 performs transmission at a period due to the output of the means 5, the generation of a correlation signal can be prevented and detection high in reliability can be performed.

Alternatively, the above mixture is filtered to form a cake and then above solvent is infiltrated into the cake and the resultant cake is rolled to form the sheet. Subsequently, the sheet is heated up to a temp. at which surfactant is not decomposed, to evaporate the above solvent and thereafter dipped in the fluidized solvent tank using a solvent such as toluene, etc., to completely elute and remove the surfactant and to form the reaction layer sheet. The reaction layer sheet is cut and a catalyst such as Pt, etc., is deposited on the cut reaction layer sheet. The cut sheet contg. the catalyst is heated and pressed to form the electrode. Thus, the gas diffusion electrode, which has a long life and is not deteriorated even at the time of using it over a long period of time, can be manufactured.

Filed: 1991-08-22
Abstract: PURPOSE:To provide a heat engine in vacuum which is excellent in the converting efficiency of thermal-mechanical energy and light, and semipermanently driven without using limited fossil fuel, and has simple structure. CONSTITUTION:A belt 3 spread between pulleys 2 is heated by moving it from a radiation cut-off section 6 to a radiation absorbing section 7 to instantly alter its shape into a shortened coil shape being previously stored. On the other hand, the belt 3 being in movement through the radiation cut-off section 6 is naturally cooled there, and the belt 3 formed of a coil is drawn out by tensile force caused by the shape alteration of the belt 3 being in movement through the radiation absorbing section 7. Thus the pulley 2 is rotated by driving force generated by the shape alteration caused in the belt during the process where the belt moves through the sections 6, 7.
