Title: Production of powder coated with non-magnetic stainless steel
Inventor: SAIDA JUNJI
IPC: G11B33/14
Filed: 1997-07-30
Abstract: PROBLEM TO BE SOLVED: To inexpensively produce a powder coated with non-magnetic stainless steel, having stabilized austenitic structure while obviating the necessity of the use of a target containing large amounts of expansive Ni, by incorporating N effective as an austenite-forming element from an atmosphere into a coating layer. SOLUTION: Powder grains are coated with stainless steel by a sputtering method while rotating a rotating barrel charged with the powder grains at >=0.1 m/min peripheral speed. At this time, N2 gas is mixed at 5-50% partial pressure ratio into the reduced-pressure atmosphere during sputtering to form a coating layer where the crystallite diameter computed from the half-width of X-ray diffraction peak of coating layer is regulated to 5-100 nm and also the Ni equipment Nieq , computed from Nieq =[%Ni]+30×[%C]+0.5×[% Mn]+25×[%M], is regulated to 6-30 mass %. The coating layer has a stainless steel composition containing, e.g. by mass >=4% Ni, 12-30% Cr, and >=0.05% N.

IPC: F04C29/02
Filed: 1989-08-07
Abstract: PURPOSE:To prove the compression efficiency of refrigerant gas by positioning a refrigerant gas outlet end part of an intake pipe in a cylinder low-pressure chamber, by arranging the axial direction of the intake pipe so that it crossed the refrigerant gas which flows into the low-pressure chamber, and by forming an oil scavenge hole in the low-pressure chamber so as to carry out efficient oil separation in the refrigerant gas. CONSTITUTION:An end part 9a at a refrigerant outlet of an intake pipe 9 is directly positioned at a cylinder low-pressure chamber 11a of a compression element 3, the axial direction of the intake pipe 9 is arranged so that it crosses the flow direction of refrigerant gas flowing into the low-pressure chamber 11a, and an oil scavenge hole 17 is formed so that it communicates with the inside of a closed container 1. As a result, oil separation can be efficiently carried out even if a conventional intake muffler is omitted, separated oil can be smoothly drained into the closed container 1, and influence of the high temperature refrigerant gas in the closed container 1 invaded from the oil scavenge hole 17 can be restrained to the minimum, which results in higher compression efficieny of the refrigerant gas.

Title: Time base controller for optical disk recording and reproducing device
Inventor: YOKOGAWA FUMIHIKO
IPC: H04N9/89
Filed: 1989-08-07
Abstract: PURPOSE:To obtain the phase jitter of spindle servo equivalent to a case using a horizontal synchronizing signal by setting the resolution of phase control for a spindle servo system smaller than that of a time base servo system. CONSTITUTION:A phase counter 13 is turned to a count enable state and executes counting operation in a period when the level of a delay enable signal is high. On the other hand, in a spot deviated to the counting enable signal only by one field, a clearing signal is generated by a timing generation circuit 11. This signal is delayed by a variable delay circuit 12, becomes a delay clearing signal and is supplied to the phase counter 13. Consequently, counted data form trapezoidal waves and the inclined part of the data is synchronized with a composite synchronizing signal to be a time base reference signal which is generated in the prescribed position of a time base. When phase control is loaded by this trapezoidal wave, phase leading-in is executed in the inclined part and by setting the resolution of the phase control smaller than the time base control range of the time base servo system, the phase jitter of the spindle servo equivalent to the horizontal synchronizing signal can be obtained.

Title: Inverter control method and its equipment
Inventor: PLATNIC MICHEL
IPC: H02M7/5387
Filed: 1997-07-30
Abstract: PROBLEM TO BE SOLVED: To make it possible to control a motor in wide ranges of speed and load and to improve a torque and speed control capacity, by shortening the duration of other pulse width modulation signal contained in the same subordinate cycle by a certain value, and by compensating the increment defining a measuring interval by the sum of the shortening. SOLUTION: In a pulse width modulation period, if a time interval between the switching of switching means 8, 10 and 12 of one phase and the switching of switching means 9, 11 and 13 corresponding to the subsequent phase becomes smaller than the predetermined threshold value, then the measurement is stopped, a pulse width modulation signal defining a measuring time interval of a sufficient duration is generated and the effect of switching for a line current is made measurable. And, the duration of other pulse width modulation signal contained in the same subordinate cycle is shortened by a certain value, and an increment in the pulse width modulation signal defining the measuring interval is compensated by the sum of the shortening of other pulse width modulation signals.

Title: Memory of information
Inventor: YURUGEN PEETAAMAN
IPC: G11B7/24
Filed: 1989-08-09
Abstract: PURPOSE: To utilize a uniaxially oriented polymer thin layer directly for information reading without another development process by changing the orientation of the polymer layer according to the information to be locally stored by high energy radiations in the polymer layer. CONSTITUTION: The orientation in the polymer layer is locally changed according to the information to be stored by the high energy radiation in the uniaxially oriented thin polymer layer. At this time, the range where the electromagnetic lines of a mask are not transmitted protects the polymer thin layer of the range existing thereunder, thereby making the polymer layer invariable. On the other hand, the orientation of the polymer thin layer is changed in the range where the electromagnetic lines of the mask are transmitted. Namely, the information to be generally destroyed and stored is written into the polymer thin layer and thereafter, the written information is readable. Anther development process for this purpose is not required. As a result, the information memory method which is widely and generally applicable is created.

Title: Correction vector storing/setting system for numerical controller
Inventor: SASAKI TAKAO
IPC: G05B19/404
Filed: 1991-07-23
Abstract: PURPOSE:To omit the need to input again a command for a correcting function when a power supply is applied again even though the power supply is turned off in a machining process. CONSTITUTION:The correction value and the correction vector of a correcting function are stored in a nonvolatile memory (S5, S7) in the sections (S1, S8) where the correcting function is kept valid. When a power supply is applied again, the correction value and the correction vector are automatically read out of the nonvolatile memory and set. Thus it is not required to input a command for the correcting function when the power supply is applied again.
Patent JP-H0370805-A (JP)
Title: Controlling method of compound generating plant
Inventor: NAGATA KAZUE
IPC: F01K23/10
Filed: 1989-08-10
Abstract: PURPOSE:To eliminate a gas turbine trip caused by rough burning by either reducing the steam turbine output to an output, which is lower than an ordinary output, or making run-back, when a load dump takes place. CONSTITUTION:If a load dump contact 14 of a load dump detecting circuit 17 is turned on, when a load dump takes place, a relay 26 is excited, and its auxiliary contact 26a is turned off, while another auxiliary contact 26b is turned on. Owing to this switching, automatic selection is made from governing ratio of 1/R1, 16a, to another governing ratio of 1/R2, 16b. As a result, a steam turbine control valve 13 is operated at a high governing ratio only when the load dump takes place. Therefore, the output of a steam turbine 6 is suppressed to a governing ratio which is lower than an ordinary one, and, as a result, a gas turbine 3 is continuously operated at an high output. Accordingly, stabler, low-load operation of the gas turbine 3 can be obtained, thereby increasing the possibility of continuous, isolated operation of the turbine within the plant.
