Filed: 1992-07-08
Abstract: PURPOSE:To realize stabilized convergence operation of positioning without causing oscillation. CONSTITUTION:Resultant position from preceding positioning is set as an initial position for positioning operation at the time of starting positioning, and another satellite is caught if a selected satellite is out of view, and then the number of satellite having highest receiving power among a plurality of satellites thus caught is delivered to an initial position setting means 12c. The initial position setting means 12c calculates an initial position from the position of satellite having highest receiving power and delivers the initial position to a memory means 13 for the purpose of modification. If on incoming radio wave has highest field strength, it is anticipated that the satellite is closest to the zenith and a decision is made that the cross point of a line connecting the satellite and the center of the globe and the surface of the globe is closest to an actual positioning point and then the cross point is set as an initial position. This constitution realizes stabilized convergence operation of positioning through sequential proximation without causing oscillation while reducing the number of times of convergence operations.

Title: Exchange of laser medium gas for gas laser
Inventor: YACHI TORU
IPC: H01S3/223
Filed: 1987-07-22
Abstract: PURPOSE:To reduce gas exchange time and gas consumption by raising the pressure of the gas in an oscillation tube to more than the atmospheric pressure at downtime, and at starting, by exhausting one kind of gas of a plurality of gases composing laser medium gas to partial pressure necessary for operation and injecting the other gases to the partial pressure necessary for operation. CONSTITUTION:A second control valve 13 is opened at downtime and N2 gas is injected in an oscillation tube 1. The gas pressure in the oscillation tube 1 is constantly monitored by a gas sensor 2 and when it attains 850 Torr, the second control valve 13 is closed. Since the pressure 850 Torr is higher than the usual atmospheric pressure, foreign material in the atmosphere is prevented from entering the oscillation tube 1 at downtime. Then at starting, N2 gas is exhausted to leave only 37.8 Torr that is the necessary partial pressure in the laser medium gas at operating. After that, a control valve 11 is opened to inject CO2 gas and He gas in the oscillation tube 1. When the gas pressure in the oscillation tube 1 reaches 120 Torr, the first control valve 11 is closed. CO2, N2, and He gases are involved in the gas thereby providing the specified pressure needed for oscillation.

Title: Alternative processing method for optical disk
Inventor: SEGAWA HIDEKI
IPC: G11B20/10
Filed: 1989-07-14
Abstract: PURPOSE:To prevent data from defectively read in a guaranteed period and to shorten time for writing by changing an alternative processing condition according to the passage of time after the date of manufacture, which is recorded to a disk as data, and the position of the optical disk in a radial direction. CONSTITUTION:The date to manufacture the optical disk is recorded to a certain area in the optical disk. When this optical disk is used by a drive, the date to manufacture the optical disk is read by the drive and the guaranteed limit is calculated from the date. Then, the alternative processing is executed by using the alternative condition considering only a margin to the guaranteed limit. In the case of a fixed rotating speed system, the size of a recorded bit is made different in the inner and outer circumference parts of the optical disk and jitter is adverse in the inner circumference part rather than the outer circumference part. Then, error is easily generated. Thus, by changing the alternative processing condition corresponding to the position in the radial direction, this trouble can be excluded.

Title: Sampling phase control system of receiving part of modulating and demodulating device
Inventor: KOBAYASHI EIICHI
IPC: H04L7/06
Filed: 1982-10-19
Abstract: PURPOSE:To reproduce correctly a transmission code despite the variance in phase relation between a sampling signal and a data signal, by controlling the sampling signal in phase. CONSTITUTION:If a sampling signal changes in phase and an automatic equalizer 3 is inactive owing to the switching of transmission lines, a code error detector 6 detects an offense of the coded side and generates a pulse (i). This pulse (i) is applied to a counter 15 through an AND gate 14. While a timer 18 resets the timer 18 in a fixed time interval. Therefore if pulses (i) are frequently produced, the counter 15 counts a fixed number of these pulses. Thus the logic ''1'' is delivered from a decoding circuit 16, and a monostable multivibrator 19 is triggered to produce a control signal (e). As a result, the phase of a sampling signal is controlled until the equalizer 3 is active.

Title: Spool type electromagnetic pressure control valve
Inventor: KAWABATA FUMIAKI
IPC: F16K31/06
Filed: 1990-07-10
Abstract: PURPOSE:To avoid lowering in accuracy of pressure reduction by partitioning a space inside a housing into a drain chamber and an air chamber, and making a bellows type partitioning member of which corrugations are aligned in the sliding direction of a spool, of a partitioning member allowing a slide of the spool. CONSTITUTION:When exciting current to a coil 100 is reduced, a control pressure port 74 communicates with a second low pressure port 72 and a brake fluid flows back to a reservoir 36. At this time, fluid pressure inside a pipe line connecting the second low pressure port 72 to the reservoir 36 rises temporarily and works on a bellows type partitioning member 90, and force in the retreat direction is added to the spool 52. This force becomes smaller the more the diameter of the bellows type partitioning member 90 is small. Since the bellows type partitioning member 90 permits a slide of the spool 52 through expansion and contraction of a corrugation part 97, the diameter is available to be made small, and if fluid pressure inside a drain chamber 94 increases, the force working on the spool 52 in the retreat direction is small. Consequently there is no excessive retreat of the spool 52 at the time of pressure reduction and a lowering of accuracy in the pressure reduction control is avoidable.
