Title: Production of compound semiconductor single crystal
Inventor: YABUKI SHINJI
IPC: C30B11/14
Filed: 1997-04-17
Abstract: PROBLEM TO BE SOLVED: To provide a process for producing a compd. semiconductor single crystal having good reproducibility. SOLUTION: A seed crystal 11 having a carrier concn. higher than the concn. of the crystal to be actually produced is used, by which the thermal conductivity of the seed crystal 11 is made better than the thermal conductivity of the crystal when the thermal conductivity is compared (generally, the electrons in the substance of a metal play a role of propagating heat. There is, therefore, a tendency that the thermal conductivity is high if the carrier concn. is high and GaAs is not an exceptional case). Consequently, the heat eventually flows from the side of the lower thermal conductivity toward the side of the higher thermal conductivity, i.e., the heat eventually flows from the crystal toward the seed crystal 11, by which the radiation of the heat from the seed crystal 11 is accelerated. As a result, the hollowing of the solid liquid boundary is prevented.

Filed: 1987-04-22
Abstract: PURPOSE:To eliminate a sudden release of hydraulic pressure and to prevent the generation of shock noises by delaying the opening operation of a solenoid which drains the hydraulic pressure in a fail condition for a specific time after an engine OFF signal is issued. CONSTITUTION:Between an oil feeding pipe 30 and an oil drainage pipe 31 at the rear wheel side, a solenoid valve 67 to bypass the hydraulic pressure of the oil feeding pipe 30 to the oil drainage pipe 31 is furnished, and it is controlled to open and close by the output signal of a control unit 100. When a failure of the electric system is detected by the control unit 100 in case of such a condition, a fail signal is input to the solenoid valve 67 to open the valve 67, and the hydraulic pressure is drained. Since a hydraulic pump 20 is rotating in the inertia after the engine is OFF, the hydraulic pressure is acting to the oil feeding pipe 30. As a result, the solenoid valve 67 is operated after a specific time of delay by a timer 68, immediately after the engine OFF, and a sudden release of the hydraulic pressure is prevented.

IPC: H04L7/00
Filed: 1992-03-27
Abstract: PURPOSE:To reduce the circuit scale without changing a frame phase of a signal by implementing transfer of an in-equipment clock and replacing a pointer at the output of a low-order group signal of an active reception unit. CONSTITUTION:A selection section 103 of an active system 106 selects an output of a reception section 101 or an output from a standby system 108 via a branch circuit 102 and sends the selected output to a pointer replacement section 105. The replacement section 105 transfers the clock into a clock generated by an in-equipment clock source 104 in frequency-synchronization with a synchronization system reference clock and replaces a pointer and sends the resulting signal to a subordinate equipment. An output of the active system reception section 101 is selected in the normal state and an output of the circuit 102 is selected on the occurrence of a fault. Then the replacement section 105 transfers the clock to the clock from the clock source 104 and changes the pointer of the signal to be sent based on the frame phase generated by the clock source 104. Thus, the circuit scale of the memory is reduced without changing the phase of the frame to be sent.

Title: Scroll shape machining device
Inventor: KOSAKA GENZO
IPC: B23Q27/00
Filed: 1988-04-25
Abstract: PURPOSE:To enable accurate machining without any correction of machining data even if the radius of a cutting tool changes due to the abrasion and exchange thereof by making the tool shiftable independently in a U-axis direction parallel to an X-axis in a cutting direction and shifting the tool with the U-axis by the same amount as a variation upon change of a tool radius. CONSTITUTION:A control part 13B drives a servo motor for shifting a tool holding part 42 in a U-axis direction on the basis of a variation in tool radius entered from an information processing part 13A and the tool holding part 42 is thereby shifted by the same amount as the variation of a tool radius. As aforementioned, a tool 6 or a tool rest 42 is shifted in the U-axis direction by the same amount as the variation of the tool radius when the radius of the tool 6 changes due to the wear or exchange of the tool 6 in a scroll shape machining device, thereby enabling the correction of the change of the radius of the tool 6. In other words, the U-axis direction is in parallel to an X-axis as a cutting direction, and when the tool 6 is shifted in the U-axis direction by the same amount at the variation of the tool radius, a machining position can be made constant without any change and correction of machining data (X.Y.C.T data).
