Title: Compound semiconductor vapor growth equipment
Inventor: SAKAGUCHI HARUNORI
IPC: H01L21/205
Filed: 1985-11-28
Abstract: PURPOSE:To enable a substrate crystal to be easily assembled and disassembled, by sealing an upper reactive tube and a lower one to unify them and making a shape similar to a streamline shape comprising a rectifying cap, a susceptor, and a susceptor holding member so that a super-thin film crystal can be produced with reproducibility. CONSTITUTION:A substrate crystal 9 is held at the most upstream side to a gas flow on a substrate holding plane of a susceptor 1 by a bump installed beforehand in a carbon pin or the susceptor 1. Then, as covering a streamline shape 3 comprising a rectifying cap 2, the susceptor 1, and a susceptor holding member 3, an upper reactive tube 4 and a lower one 5 in the similar streamline shaped are sealed. Thereafter, while the susceptor holding member 3 is rotated, reactive gases such as TMG and AsH3 are introduced with high-purity hydrogen from a lower introduction port 5b, passing through the reactive tube, and being exhausted from an upper exhaust port 4b. At the same time the susceptor 1 is induction-heated by a high frequency coil 8, to heat the substrate crystal 9. Thus, film-thickness control can be stably realized without producing an eddy and a backward flow caused by disturbance of a gas flow.

IPC: G11B5/187
Filed: 1992-09-10
Abstract: PURPOSE:To reduce man-hours and to shorten the time for working as well as to decrease the amt. of the resin to be used and the cost of production by enabling the sufficient packing of the resin into a case by one time of resin pouring. CONSTITUTION:A front face aperture 7 on the front end face of a magnetic head 1A is fitted into a recessed part 19 by imposing an air permeable sheet 2 on the base 19A of the recessed part 19 of a receiving base 18 so as to seal the base and is pressed to the base 18. The base 18 is made of an elastic resin and since the transverse width U of the recessed part 19 is slightly smaller than the transverse width V of the case 6, the base can be held in a tight contact state by fitting the head 1A. The epoxy resin is injected in this state into the space in the case 6 and is thermally cured. The head sealed and fixed by the epoxy resin is thereafter taken out of the base 18 and the sheet 2 is peeled. The magnetic recording medium traveling surface from which the front end face of the head core 8 projects is polished to a smooth surface, by which the magnetic head is produced. As a result, the man-hours and the time for working are reduced by half and the magnetic head is easily produced.

Title: Picture switching control system in multitask
Inventor: YOSHIDA NORIO
IPC: G06F3/048
Filed: 1985-11-30
Abstract: PURPOSE:To reduce a time required to switch a program, and to reduce the capacity of a main memory area by providing the same number of screen memories as that of simultaneous execution possible programs. CONSTITUTION:It is assumed that the picture image of a program 11 is positioned at a VRAM21, and that of a program 12 at a VRAM22, and that of a program 1n at a VRAM2n. While the program 11 is executed, the image of the VRAM21 is displayed on a CRT scope 4. At such a time, when the switching of the program is required and a control is shifted to the program 12, the image of the VRAM22 is displayed simultaneously on the CRT scope. Thus, by performing the switching of the control of the program and those of VRAMs 21-2n simultaneously when the switching to programs 11-1n is required, it is possible to switch rapidly the picture display, and the usage quantity of the main memory can be reduced.

Abstract: PURPOSE: To easily confirm a guide point according to a voice message on a map. CONSTITUTION: The image of map data 23 appears on a display 22 with the position of an own vehicle which is detected by an own vehicle position detection device 20 as a center. One or a plurality of guide points are set from an input device 24 on the preset driving path of a vehicle.

Title: Switching device
Inventor: TANAKA YASUNORI
IPC: H02J3/00
Filed: 1995-10-17
Abstract: PROBLEM TO BE SOLVED: To improve efficiency when a load is light by disconnecting a frequency-variable resistor which is connected to the oscillation constant element of a control circuit in parallel from a control circuit by the light load signal of an electronic equipment and reducing the switching frequency when the load is light. SOLUTION: When a light load signal of 5V of a signal terminal s1 is applied, a photodiode Pd emits light and a photodiode Pt conducts. Then, a resistor R0 is short-circuited, the base bias voltage of a transistor Tr reaches 0, and the transistor Tr is disconnected. A frequency-variable resistor R4 is electrically disconnected from an oscillation resistance element Rt of a control circuit Ic and a resistor connected to an oscillation resistor element R5 becomes only the resistor R0 for oscillation, thus increasing the resistance as compared with the synthetic resistance of the frequency-variable resistor R4 and the resistor R0 for oscillation when load is heavy and decreasing an oscillation frequency for coping with a light load.

Filed: 1990-10-05
Abstract: PURPOSE:To make reading operations and writing operations simultaneously executable when a read level is not equal to a write level by registering the level obtained by indexing an address array with a write address in a storage buffer. CONSTITUTION:The need of indexing an address array 1 at the time of writing in data arrays 2 and 3 from a store buffer 8 is eliminated from this cache storage device by simultaneously registering a write level obtained by indexing an address array with the write address to a cache storage when the write address is registered in a store buffer 8 and, at the same time, the storage device is provided with divided data arrays which are obtained by dividing the data arrays 2 and 3 by addresses or levels and can independently make writing/reading operations. Therefore, when the divided data array to be read is different from the divided array to be written, reading operations can be performed simultaneously with writing operations.
