Title: Control device for variable displacement pump
Inventor: UNO KEIICHIROU
IPC: F04B49/08
Filed: 1982-07-29
Abstract: PURPOSE:To effectively utilize an output in the case that pressure loss in a circuit is large, by raising a relief cut-off set pressure when a specific hydraulic actuator of a power shavel is in operation. CONSTITUTION:When a travel selector valve is in its neutral position and a travel pressure Pa is nearly zero, a selector valve 18 is in a position A and a discharge pressure Pp is supplied to pressure receiving sections 15a and 15b. Accordingly, when the discharge pressure Pp becomes equal to or higher than a relief cut-off set pressure PR1 during unoperation of a travel motor, a control valve 15 is switched to a position B, and thereby to communicate a cylinder chamber 9a with a tank and to move a servo piston 9 to its left end. As a result, a discharge flow Q of a pump 2 is reduced to a minimum value QR. On the other hand, when the travel selector valve is in its operational position, and the travel pressure Pa is increased from the nearly zero value, the selector valve 18 is switched to a position B, and the discharge pressure Pp is supplied to the pressure receiving section 15a, while not being applied to the pressure receiving section 15b. Accordingly, when the discharge pressure Pp becomes equal to or higher than a relief cut-off set pressure PR2, which is higher than the set pressure PR1, during operation of the motor, the control valve 15 is switched to the position B, and therefore the discharge flow Q reaches the minimum value QR.

Title: Data restoration method for distributed transaction processing system
Inventor: KOBAYASHI SEIICHI
IPC: G06F15/177
Filed: 1989-05-25
Abstract: PURPOSE:To restore data consistent with other server side system even if the server side system falls into system-down at any timing by providing a means to hold transaction processing finish information and the means to restore the data and so on. CONSTITUTION:Distributed transaction processing systems 101 to 10n are connected to each other respectively through a line 1. Transaction processing consists of two stages of first stage processing (buffer write-out processing) and second stage processing (processing to reject journal data and release exclusive resource). When the system falls into the system-down after a transaction processing finish procedure vicariously executing part 12 starts the second stage processing, a transaction processing control part 11 inquires first stage processing finish information of the transaction processing procedure vicariously executing part 12, and receives the first stage processing finish information, and executes the second satage processing. Thus, even if the system falls into the system-down, the consistent data can be restored.

Title: Encoder for detecting magnetic pole of pm motor
Inventor: OGURI HIROSHI
IPC: H02K21/12
Filed: 1999-05-13
Abstract: PROBLEM TO BE SOLVED: To simplify a signal transmission method, to enable detection with a small-scale circuit, and to enable omission of wiring by outputting a duty factor representing a magnetic pole position as a pulse signal continuously, and detecting the magnetic pole position. SOLUTION: Four signals of phase A/phase B/phase Z/RT are outputted from a position detector, and an RT signal is a pulse signal which represents position (mechanical angle) information by a duty factor. Namely, a mechanical angle is represented by a duty factor of on-duration/ off-duration, and the period of repetition represents one rotation of the mechanical angle, and the position of a magnetic pole is detected by on-time/off-time. A controller receives this signal, computes on-time/off-time, and confirms a present magnetic pole position. After controlling power on the controller side is supplied, identification of the initial value of the magnetic pole is performed, and operation is made possible, and zero degree of the mechanical angle is detected by an input of phase Z.  Detection of the pole position becomes feasible by counting pulses of phases A and B, after inputting the phase Z.

Title: Method for measuring transmitted amount of vapor for material
Inventor: MAYER WILLIAM N
IPC: G01N15/08
Filed: 1998-05-14
Abstract: PROBLEM TO BE SOLVED: To make it possible to measure the transmitted amount of vapor for material accurately by filling a liquid source in a chamber having the wall selected from various kinds of materials, forming another chamber, which is linked to an inactive gas source at the outside of the wall, diffusing the vapor into the chamber and the material and measuring the transmittance. SOLUTION: A test chamber 10 has lower and upper compartments 12 and 14. A sample film 16 is clumped between the compartments 12 and 14. The vapor emitted from a liquid source 20 contained in the compartment 12 is diffused in the entire chamber formed between the film 16 and the compartment 12. A small ventilating aperture 11 penetrates the wall of the compartment 12. The entire pressure in the compartment 12 becomes equal to the outer atmospheric pressure. Then, inactive carrier gas such as nitrogen is made to flow into the upper chamber formed between the film 16 and the compartment 14 through an inlet 22 and flow out from an outlet 24. The amount of transmission is measured with a vapor detector 30.

Title: Single crystal production unit
Inventor: OKADA HIDEO
IPC: C30B11/00
Filed: 1992-05-25
Abstract: PURPOSE:To provide a single crystal production unit designed to improve the quality of single-crystal by providing a gas flow baffle close to the solid-liquid interface. CONSTITUTION:A seed crystal 6 is put at one end of a crucible 5 held by a susceptor 4. The crucible 5 is then charged with a group III-V compound semiconductor material such as GaAs polycrystal and a sealer 9 such as B2O3 and the material is heated and melted through an exothermic element 3 along with application of electric power on an auxiliary heater 13 in an Ar atmosphere. The heat disturbance near the solid-liquid interface 10 due to the convection of a gas filled is controlled by a gas flow baffle 12 set at the same level as that of the interface 10 between a single crystal 7 and a material melt 8. Also, owing to the set position for the auxiliary heater 13, the temperature gradient on the solid side of the interface 10 is allowed to get gentle, preventing unnecessary heat from being given to the liquid phase and controlling thermal flow disturbance. The seed crystal 6 is grown and pulled up to obtain the objective single crystal 7 with high quality.

IPC: G08C25/00
Filed: 1989-05-29
Abstract: PURPOSE:To recognize a line level without a line tester and to facilitate the investigation of a cause when transmission abnormality occurs by always displaying the line level. CONSTITUTION:The band pass filter circuits of line level detection parts 8a and 8b fetch only the frequency band of a reception signal. An AC/DC conversion circuit converts the AC signal into a DC signal proportional to an amplitude, decibel operation parts 9a and 9b consisting of LOG amplifiers convert it into decibel values and line level display parts 10a and 10b always display numerals. Thus, the line level can always be supervised without the need of the line tester, and the investigation of the cause is facilitated when the transmission abnormality occurs.
