Title: Production of compound semiconductor single crystal having high decomposition pressure
Inventor: KOJIMA MASAKATSU
IPC: C30B27/02
Filed: 1983-01-18
Abstract: PURPOSE:To produce a single crystal of a compound semiconductor having high decomposition pressure, in high yield and workability, by detecting the pressure in the bomb for supplying an inert gas and in the closed vessel, and controlling the feeding or discharging flow rate of the inert gas according to the detected data. CONSTITUTION:An inert gas is supplied from the bomb 15 to the closed vessel 1 in the growth of a compound semiconductor crystal having high decomposition pressure, e.g. GaP, etc. The pressure of the inert gas is controlled to keep the output level of the pressure sensor A36 at a constant level. The pressure in the vessel 1 is detected constantly during the pulling of the crystal by the pressure sensor B34, and the difference of the output signals of both sensors 34 and 36 is converted to an electrical signal by the device C37. When the pressure difference exceeds the preset level, the solenoid valve V1 (25) of the bypass discharge line 26 is opened and the inert gas is discharged from the system little by little through the needle valve V2 (27). As an alternative method, the solenoid valve V3 (31) of the bypass feed line 30 is opened, and the inert gas is supplied to the vessel 1 through the needle valve V4 (32). The lowering of the yield of a single crystal caused by the pressure fluctuation in the vessel can be prevented by this process.

Title: Preventing decarburization of high silicon spring steel material
Inventor: SATOU MANJIROU
IPC: C21D9/52
Filed: 1979-01-25
Abstract: PURPOSE:To reduce cost through preventing decarburization of ferrite to occur on the surface layer of steel material by specifically controlling cooling after hot-roll of spring-steel material contng. 1-3% of Si. CONSTITUTION:Spring-use steel material contng. 1-3% of Si is hot rolled and then cooled in the temperature range of 750-600 deg.C at a cooling rate between 15 deg.C/min and 200 deg.C/min. This condition enables to prevent ferrite from being decarburized without producing structure due to high-speed cooling. This cooling rate is easy to achieve by passing air through coiled steel wound in usual way after rolling operation. The process allows cooling rate faster than the conventional natural cooling, and therefore is effective in reducing production cost and can eliminate cutting or grinding work that is conventionally needed before spring formation.

Title: Microwave frequency converting circuit
Inventor: HIRAI KENJI
IPC: H03D7/16
Filed: 1987-01-14
Abstract: PURPOSE:To attain the small size in the local oscillation system and the low cost by using a frequency multiplier so as to multiply an output of a common local oscillation source at an optional multiple thereby obtaining a local oscillation input to plural frequency converters. CONSTITUTION:A 1st local oscillation circuit of a 1st frequency converter 21 employs only the common local oscillation source 22 without any multiplier and a 2nd local oscillation circuit of a 2nd frequency converter 25 consists of a multiplier 27 whose number of multiple is N and the common local oscillation source 22. A base hand signal frequency fl is lifted by a 1st local oscillation frequency fL by the 1st frequency converter 21 and becomes an intermediate frequency (IF)f2. The signal is amplified to a prescribed level by an IF band amplifier 24 and increased by a local oscillation frequency NfL at the 2nd frequency converter 25 and converted into a transmission frequency f3. Thus, only one set of local oscillator is enough for the application and the external size is decreased and the adjustment time is reduced, resulting in reducing the cost.

Title: Guiding device
Inventor: TSUMAKI NOBUO
IPC: F16C29/02
Filed: 1984-01-20
Abstract: PURPOSE:To enable the position of a slider to be corrected to the specified position, by detecting the displacement of the slider from the coordinate and by adjusting the pressure exerted from the pressurizing fluid supply means in accordance with the signal from the comparator which compares the measured value and the stored reference value. CONSTITUTION:When a base 1 which guides a slider 2 is distorted or bent, the amount of distortion or bending is detected by sensors 7, 8 and input to controllers 9, 10. Then the measured value of the distance between the sensors 7, 8 and the slider 2, and the set value stored in storage sections 9A, 10A are compared in comparators 9B, 9C. The control sections 9C, 10C examines the result of comparison and output control signals to control valves 5A, 5B, 5C, 5D, so that the opposing spaces G can be maintained at the prescribed distance. The control valves 5A-5D adjust the pressure of the pressurizing fluid supplied to the spaces G and thus correct the position of the slider 2 in X- or Y-direction. Thus, the slider 2 can be placed at the desired position accurately.

Title: Signal input device of microcomputer
Inventor: KOBORI YASUNORI
IPC: G06F13/42
Filed: 1982-01-22
Abstract: PURPOSE:To decrease a quantization error of an input signal enough to use it even for a high-precision control system by adding the detection output of a counter means to information detected on the basis of a machine cycle. CONSTITUTION:While a control signal CTL from a microcomputer 1 is at a level H, the input of a signal A is held in readiness. At this time, the output of an inverter 10 is at a level L and the output of an NAND8 is at the level H. On the other hand, the input signal A is at the level L, so a counter 6 is reset. Once the input signal A is inverted to the level H, a request for interruption is sent out to the microcomputer 1, but the microcomputer 1 detects that a specific time later. During this period, the counter 6 counts a high-speed clock signal CPH. Therefore, the counted value of the counter 6 is inputted simultaneously with the fetch of the signal A, and consequently its detection error is suppressed within one cycle of the high-speed clock signal CPH.

Abstract: PURPOSE:To prevent a data on a magnetic recording means from being destroyed by providing a data detection means generatiang a signal for blocking write current supply when a signal characteristic is a prescribed value or below at no input of a write data signal. CONSTITUTION:When no write data signal 10 is inputted, an output of a one- shot circuit 33 of a data detection means 70 goes to L, a transistor (TR) Q5 is turned off. Thus, the base of a TR Q1 reaches the same level as a power supply +V1, the TR Q1 is inoperative, no voltage across a diode D1 is generated, a write means 30 is brought into the inoperative state to block the power application to the magnetic head 32. Simultaneously, an error signal 20 representing a data error is outputted from a gate 34, sent to a write read control circuit, where the writing is stopped and an error is reported to a host device.

IPC: H02P27/06
Filed: 1993-01-20
Abstract: PURPOSE:To obtain a power converter and a method for controlling in which a charged state of a battery for supplying a DC to an inverter to be regenera tively operated is controlled. CONSTITUTION:A battery 4 is connected to a DC circuit for connecting a converter 1 to an inverter 2, and at the time of operating the inverter 2, the battery is discharged to the inverter 2 until a voltage detected value 5 of the battery becomes a set value (a voltage lower limit value) of a voltage instruction unit 6. In order to control a discharging current of the battery 4, the discharging current is detected by a detector 8, its value is inputted to a current regulator 9 of the converter 1, and a current of the converter 1 is controlled. Thus, since a battery voltage is held at a preset lower limit value, regenerative power can be absorbed to the battery to a maximum limit. A regenerative inverter is eliminated to simplify its configuration.
