Title: Method of manufacturing semiconductor device and epitaxial growth apparatus
Inventor: MATSUO TETSUJI
IPC: H01L21/208
Filed: 1999-11-08
Abstract: PROBLEM TO BE SOLVED: To suppress the melt back of semiconductor materials and efficiently epitaxially grow semiconductor layers. SOLUTION: The top end of a cooling gas feed pipe 5 is disposed below a support container 1 housing a semiconductor wafer W, a gas feeder 6 provided outside a process chamber 3 feeds nitrogen gas, etc., to the cooling gas feed pipe 5, and the fed gas is cooled during passing through a portion wound with a cooling water piping 6 and discharged on the lower surface of the semiconductor wafer W from a gas discharge hole 51 formed at the top end of the cooling gas feed pipe 5. While a semiconductor layer epitaxially grows on the semiconductor wafer W surface, the lower surface of the wafer W can be cooled enough to suppress the melt back of GaP deposited on the wafer W surface, and thus the semiconductor layer can be efficiently epitaxially grown.

Title: Method for working steel rod into eliptic ring
Inventor: AKEI KATSUHIKO
IPC: E04C5/00
Filed: 1994-11-15
Abstract: PURPOSE: To enable the mass-production of a deformed ring in a low cost by extending a round steel ring at plural points and working an eliptic ring or a deformed ring. CONSTITUTION: The round steel rod material 9 is laid on between a saddle type fixed jig 1 and saddle type shiftable jig 2. A piston cylinder 4 is extended and the saddle type shiftable jig 2 is shifted to work the round shape of the steel rod material 9 into the eliptic shape. The steel rod material 9 is plastically deformed by the extending operation to form the eliptic shape. The deformed ring can be worked by using plural piston cylinders 4. Instead of the piston cylinder 4, this steel rod material can be extended by using a device which connects a gear with a motor. Therefore, the eliptic ring or the deformed ring can simply be manufactured without using such an expensive working method as a changable curvature bender or a pressing work, etc.

Title: Power voltage display system for radio equipment
Inventor: SENDA SHIGERU
IPC: H04B1/04
Filed: 1989-12-11
Abstract: PURPOSE:To display the application of the power voltage, the drop of the power voltage, and the drop degree of the power voltage via a single display device by controlling the display blinking cycle in accordance with the difference between the input power voltage and the reference voltage. CONSTITUTION:A blinking control part 3 compares the input power voltage with a reference voltage level which is previously set and stored. Then a blinking display part 4 sets a blinking cycle based on the difference between both voltage levels. When the power voltage is higher than the reference level, the continuous blinking display is carried out. Meanwhile the display blinks with a frequency proportional to the difference between both voltage levels when the power voltage is lower than the reference level. Thus a single display device 4 can show the application of the power supply, the drop of the power voltage, and the drop degree of the power voltage respectively.

Title: Phase change type optical disk
Inventor: OKADA MITSUYA
IPC: G11B7/24035
Filed: 1989-12-11
Abstract: PURPOSE:To enable satisfactory erasing under a specified condition regardless of a radial position for recording and erasing even when a disk is used under a condition fixing the number of revolution by increasing the film thickness of a recording layer between two dielectric layers from the outer periphery to the inner periphery of the disk. CONSTITUTION:On a substrate 1, a dielectric layer 2, a recording layer 3 and a dielectric layer 4 are successively formed. The film thickness of this recording layer 3 is increased from the outer periphery to the inner periphery of the disk. Since the cooling speed of the recording layer is changed according to the size of the thermal capacity of a medium, the optical disk to vary the cooling speed in a radial direction can be obtained by changing the film thickness of the recording layer 3 in the radial direction. Therefore, even at various linear velocity, the same cooling condition can be obtained and even when the disk is used under the condition fixing the number of revolution satisfactory erasing can be executed under the fixed condition regardless of the radial position for recording and erasing.

Inventor: FUKUSHIMA SETSU
IPC: G06F3/06
Filed: 1993-11-25
Abstract: PURPOSE:To shorten average seek time by adjacently arranging areas where accesses are frequently generated with each other. CONSTITUTION:The definition information of a virtual disk is assigned in order of sub-disks Sd-a1 to Sd-a5 with a prescribed width from the leading area of a physical disk. As a result of the statistics and investigation of the number of times of access at the time of an operation as for each of these sub-disks, accesses are frequently generated in order of sub-disks Sd-a1, Sd-a5, Sd-a2, Sd-a3 and Sd-4, for instance. Because sub-disks having a high access frequency with each other are adjacently arranged and are arranged at the center of the disk, the redefinition information of the virtual disk is organized in order of Sd-a3, Sd-a5, Sd-a1, Sd-a2 and Sd-a4. Therefore, the distance on the physical disk of the Sd-a1 and Sd-a5 with large access frequencies is shortened and a probability that a head stands by at the central part of the disk becomes high.

Abstract: PURPOSE:To enable reproducing operation and dehumidifying operation to be carried out in a cryopump device by a simple and positive configuration. CONSTITUTION:Displacers 106 and 108 are reciprocated within cylinders 105 and 107 and then fluid to be cooled is cooled while cooling thermal capacity is being stored in cold heat accumulating agents 202 and 207 through an expansion cooling of pressurized refrigerant 101.

A power supply for sensing insulation and another power supply for sensing a stroke as well as a heating power supply are applied to an electrical contact point 11 and a ground terminal 19 arranged at a terminal point of the stroke of the displacer 106. Deterioration of insulation between the belt like electrical heater 10 and the first cylinder 105 and humidification within the first cylinder 105 are detected in reference to variation of insulating resistance caused by the power supply of detecting insulation. A final position of the stroke is detected by a contact between the electrical contact point 11 and the electrical contact point 13 with the stroke detecting power supply.

IPC: G06F11/26
Filed: 1987-12-17
Abstract: PURPOSE:To test the memory control and the interruption relation of a developed user program by a host machine by realizing environment which a target OS controls on a target on the host machine. CONSTITUTION:A break point bp is set in a program 1 to be tested by a debugger 4, and the program start to be simulated. A CPU 13 performs vector jump, and performs interrupt processing, and after the finish of it, it is reset to a register at the time of the interruption, and the program 1 is restarted and executed from the point next to the above-mentioned bp. Thus, a pseudo hardware 10, a target OS 2 and the user program 1 can be tested by a simultaneous link form by the debugger 4. Because this test by the simultaneous link form is performed on the host machine, the control of a whole system is performed by a host OS, but in the actual simulation, it is quite unnecessary to be conscious of the host OS.
