Title: Manufacture of si3n4 sliding material
Inventor: TEJIMA YOSHIHIRO
IPC: C10N70/00
Filed: 1991-03-05
Abstract: PURPOSE:To easily form spiral grooves in the sliding surface of a sliding material. CONSTITUTION:Ions of, e.g. nitrogen or argon are injected under a prescribed accelerating voltage into one side of a sliding material body consisting of Si3N4 to give ion injection parts, which are masked to leave non-masked areas in spiral form. The non-masked areas are then subjected to shot blasting to remove the ion injection parts in the areas, thus forming spiral grooves 4 on one side of the sliding material body 2. The sliding material body 2 is then subjected to heat treatment at a prescribed temperature to cause the remaining ion injection parts to recrystallize to thereby form a sliding surface 3, thus producing an Si3N4 sliding material 1.

Abstract: PURPOSE:To uniformize the thickness distribution of the coating film of a solution on an article to be treated, by making it possible to position one arbitrary dripping nozzle among a plurality of ones at the center of the article to be treated through a centering mechanism. CONSTITUTION:In a process for coating a wafer with a photoresist, for example, when the pump P corresponding to the solution L2 among solutions L1-L3 is selected by a control part 4 and operated, the drive part 3c of a centering mechanism 3 is operated and the dripping nozzle N2 corresponding to the solution L2 is accurately positioned at the part directly above the center of an article 2 to be treated. As a result, because the solution L2 dripped from the dripping nozzle N2 is accurately dripped to the center of the article 2 to be treated, said solution L2 is uniformly dispersed and applied to the surface of the article 2 to be treated by the action of centrifugal force applied thereafter.

Title: Optical disk recording device
Inventor: HIRAI MIKIO
IPC: G11B7/0045
Filed: 1988-03-17
Abstract: PURPOSE:To improve the S/N and to decrease errors by controlling the radiating state of the laser light in accordance with the immediately preceding blank length for reduction of the error of the pit length or the blank length due to the value of the immediately preceding blank length and for reduction of jitters of the reproduced signals. CONSTITUTION:An optical head 2 radiates the recording or reproducing laser light emitted from a laser light generating circuit 3 onto the surface of a disk 1 revolving at a fixed linear speed for recording or reproducing jobs. This recording data is supplied to a data production means 4 for production of the pit length data and the immediately proceeding blank length data corresponding to these lengths respectively. Based on these produced data, a laser light control means 5 controls the time of irradiation and the irradiation start timing of the laser light. As a result, the normal pit length is obtained at an approximately normal position and therefore the error due to pit length or the blank length due to the value of said immediately preceding blank length is reduced together with reduction of the jitters of the reproduced signals. Thus it is possible to improve the S/N and to decrease errors.

IPC: H02N2/00
Filed: 1988-03-17
Abstract: PURPOSE:To simplify a calculating algorithm for determining a frequency by disposing an electro-mechanical energy conversion element in a geometrically mirror symmetrical relation by normally or reversely moving a moving body. CONSTITUTION:A piezoelectric element of an electro-mechanical energy conversion element in the stator of a hollow annular vibration wave motor has driving A-phase electrodes A1-A7, driving B-phase electrodes B1-B7, a sensor electrode S1 used in case of clockwise rotation(CW), a sensor electrode S2 used in case of counterclockwise rotation(CCW), and a common electrode C. The disposition of the electrode is so switched according to a rotating direction that the CW electrode disposition and the CCW electrode disposition become plane-symmetrical (in a geometrical mirror symmetrical manner). Thus, a sensor position becomes an equivalent position in CW and CCW dispositions, and a frequency vs. phase difference curve does not depend upon its rotating direction.

Abstract: PURPOSE:To improve the efficiency of heating energy in treating fine particles included in a waste gas, by connecting a filter, equipped with a heating means and having a heat-resistant filter medium capable of holding a large quantity of fine particles, to an exhaust pipe, and forming a by-pass provided with a changeover valve, and providing an air flow-in port on the upstream side of the filter medium. CONSTITUTION:A waste gas from an exhaust pipe 1 flows into a filter 2, and is filtered while capturing fine particles contained in the gas by a heat-resistant filter medium 5. The waste gas containing fine particles flows into a filtering chamber 8 from the inlet surface of the medium 5, and the fine particles are separated by a chamber wall 9 of the chamber 8 when the gas passes through the wall 9. When the filter 2 comes to the prescribed clogging state, an action-controlling device 15 changes over a changeover valve 12 to release a by-pass 3, and also opens a control valve 14 to make air flow into the filter 2 from an air flow-in port 13. When the temperature of the medium 5 reaches the prescribed value, the captured fine particles ignite and burn by themselves. The heating means is stopped at the time when the particles ignite.

CONSTITUTION:A transmission ratio varying device 10 to vary a transmission ratio being a ratio between the rotation angle of a steering handle 2 and the steering angle of a wheel 6 is located between a handle shaft 3 and an intermediate shaft 4 of a steering device 1. The transmission varying device 10 is controlled by a controller 11 to which signals from a car speed sensor 12 and a handle steering angle sensor 13 are inputted. Namely, the controller 11 sets a transmission ratio according to a detecting car speed and computes a wheel steering angle from the transmission ratio and a handle steering angle, and controls the transmission ratio varying device 10 according to the computing result. In this case, when it is detected that a vehicle is in a transient state, e.g. acceleration, deceleration, control is effected so that the transmission ratio is fixed to a value prevailing right before a transient state.

Abstract: PURPOSE:To prevent generation of abnormal noise and a tooth surface in an epicycle reduction gear for improving durability by keeping always the center axial lines of the armature rotary shaft and the output rotary shaft of an electric motor and an over-running clutch device aligned with each other during their operations. CONSTITUTION:In a coaxial starter 20, the front end of the clutch inner 21a of an overrunning clutch device 21 is supported on a machine frame 8 through a bearing 11, and its rear end is supported on an armature rotary shaft 23 through a bearing 25. Therefore, they have no inclination to rotary axial centers during operation and coincide with the rotary center axial line of the shaft 23. Moreover, the front end of an output rotary shaft 5 is also supported on the inner 21a through a bearing 26, and its rear end is supported on the shaft 23 through a bearing 6, and then the rotary center axial line also coincides the axial lines of the shaft 23 and the inner 21a. As a result, the respective rotary center axial lines of three mechanical elements 5, 21a, 23 which rotates conjointly in order are always kept in a coincident condition during operation. It is thus impossible for the revolutionary center of an epicyclic gear 7b used in an epicycle reduction gear 7 to deviate from the aligned rotating center line, and the gear 7b revolves around 7c, 7a and rotates on its own axis.
