Title: Differential gear propulsion engine
Inventor: YONEDA SHIN
IPC: F03G7/00
Filed: 1994-01-27
Abstract: PURPOSE:To reduce the reverse thrust of discharge cylinders to become resistance to propulsion cylinders so as to heighten power generating efficiency as a labor-saving machine by opposing the mutual thrust of plural discharge cylinders by selecting the force applying point of axial thrust of the discharge cylinders to a gear. CONSTITUTION:When a hydraulic pump 2 is driven and a solenoid valve 3 is switched on, pressure oil is fed to the left direction pressure side of cylinders 9-12 via a left direction pressure circuit 5. The cylinders 9, 10 thereby generate right direction thrust, and the cylinders 9, 10 generate left direction thrust so as to move in the left direction on the whole. At this time, the required fluid of the cylinders 11, 12 is make-up fed from the cylinders 9, 10 by differential thrust. Upon reaching the left direction end, right direction motion is performed by the switching of the solenoid valve 3 and the instantaneous operation of a pressure relief valve. The same procedure is repeated to rotate a propulsion wheel 16, with which a rack is meshed, by the reciprocating motion of the cylinders 9-12, and power can be taken off.

Abstract: PROBLEM TO BE SOLVED: To realize film formation wherein a reflow form is shown, and film thickness difference due to pattern density dependency does not exist, by controlling the boundary thickness to a substrate to be a specific value or less which substrate has difference in partial pattern density, under a specified film formation condition. SOLUTION: In the control of boundary layer thickness of material gas, a film formation condition is set as the referance which condition is the following; when film formation is performed to a substrate whose pattern density is 1, the film formation speed does not change in the case that the boundary layer thickness is changed. That is, the following are set under the above condition; the maximum thickness of a boundary layer which can be obtained in the substrate surface whose pattern density is 1 is (k), and when difference exists in the pattern density, the pattern density is (x). The thickness of the boundary layer to the substrate having difference in partial patterns is controlled to be at most k/x.  Thereby film formation wherein a reflow form is shown, and film thickness difference due to pattern density dependency does not exist can be reallized, when an insulating film showing the reflow form is formed.

IPC: B22D11/06
Filed: 1982-03-10
Abstract: PURPOSE:To improve the contact between belts and rolls and to prevent the breakage of the belts, etc. owing to abnormal expansion of the belts in a twin belt type continuous casting machine by incorporating a variable crown type for driving rolls and backup rolls for belts. CONSTITUTION:A variable crown type is incorporated for driving rolls 2 which drive belts 1 in a twin belt type continuous casting machine and many backup rolls 3 which guide the belts 1. More specifically, pressure oil chambers 10 are formed between the arbors 8 and sleeves 9 of both rolls, and further, the oil feed passages 11 from the axial center position at the end face on one side of the arbors 8 to the chambers 10 are formed in the arbors 8, and a pressure oil is supplied through rotary joints 12 to the chambers 10 to bulge the sleeves 9 outward, whereby the crown is adjusted. Since both rolls contact tightly with the belts 1 to cool the belts thoroughly, the accident that the molten metal flows out on account of the breakage of the belts by the abnormal expansion occuring in the lack of cooling is prevented.

Title: Data reading device
Inventor: ORIHARA JUNICHI
IPC: H03K17/04
Filed: 1995-02-27
Abstract: PURPOSE: To minimize the insertion of wait time even when the access time is extended. CONSTITUTION: When the wiring load capacity C5 of a data bus D is increased and the delay time of data transmission is extended, the timing when a data holding circuit 16 reads the data is delayed by a timing circuit 20. Then the data are read in a conventional unused period of the bus D that is set at the head of the next data access. Thus only the read timing is delayed and therefore the insertion of wait time is minimized. Then the extension of cycle time can be suppressed.

Filed: 1985-03-01
Abstract: PURPOSE:To decrease the transfer overhead of a write data to a storage section by designing the titled device that the storage section transfers serially a data to a write data register of the storage section in time division even when the storage section is during execution of read. CONSTITUTION:A write request (WREQ) is held in a request control section 4 until the read request (RREQ) is finished and when the RREQ is finished, an operation signal group MT is issued to a storage element group 9 to execute the write operation. Although the read is during execution when a write data is transferred attended with the WREQ, the control section 4 generates a write data transfer command to a write data transfer control section 6. Then a write data register set signal is issued four times to write serially a write data WD one by one bank in total 4 banks in time division and transfer the result to a data register 10 (WR0-3). That is, the transfer of serial write data required for the write at the next cycle and requiring comparatively time is finished.

Title: Optical transmission system
Inventor: FUKUI MASAKI
IPC: H04B10/2563
Filed: 1995-02-27
Abstract: PURPOSE: To compensate the influence of four-light-wave mixed light and waveform deterioration owing to wavelength dispersion by inserting a dispersion equalizing means having the dispersion value of a code inverse to the wavelength dispersed value of an optical fiber into the trailing end of the optical fiber. CONSTITUTION: The optical signal with a 1.5μm-band, which is transmitted from an optical frequency multiplex transmitter 1, is made incident on a normal dispersion fiber 2. In such a case, the normal dispersion fiber 2 is the optical fiber where a 1.3μm band is set to be a zero dispersion wavelength and it becomes an abnormally dispersion area against the transmitted optical signal. A dispersion equalizer 3 giving regular dispersion to the optical signal is used as that arranged behind the regular dispersion fiber 2. A dispersion compensation fiber having a negative dispersion value of the 1.5μm band and the dispersion equalizer using an optical waveguide exist as such dispersion equalizers.  The optical signal which is dispersion-compensated by the dispersion equalizer 3 is amplified by an optical repeater amplifier 4 and is made incident on the regular dispersion fiber 2 again. The dispersion equalizer 5 optimizes the whole disperse values and an optical frequency multiplex receiver 6 receives them in a final stage.

Abstract: PURPOSE:To succeedingly perform smooth filtering action, by making it possible to relatively rotating a fluid to be filtered, a scraper mechanism capable of injecting a separate fluid and a filter having a cylindrical filter element in a housing. CONSTITUTION:When a raw solution Lg is supplied to a raw solution part 1G, a pure solution Lj, wherein impurities were removed by a filter element 2e, is sent to a predetermined direction from a filter 2 through outflow ports 2a, 1a, a pure solution part 1J and a pure solution pipe 1j. When a high pressure jet fluid is flowed in from a shaft pipe 3j in parallel to the supply of the raw solution from a raw solution pipe 1g as operation for cleaning the element 2e, the raw solution sent to each scraper 3s from a flow distribution part 2b is sprayed to the surface of the element 2e from jet orifice 3a under high pres sure at a high speed. Because the scraper mechanism 3 rotates around the entire periphery of the filter 2, a stagnant filter cake is released and detached by both of the jet effect and stirring effect from the scraper 3s to eliminate clogging.
