Title: Method and device for ac square wave plasma arc welding
Inventor: FUJIYAMA HIROHISA
IPC: B23K10/02
Filed: 1985-11-28
Abstract: PURPOSE:To execute exactly an arc re-ignition at the time of converting the polarity of one set of power source, and to improve the welding operability by executing the welding by using an AC square wave voltage which can adjust optionally a frequency and a time ratio of a positive electrode component and a negative electrode component, as a welding power source. CONSTITUTION:A square wave signal which has been obtained by an oscillating circuit 6 is set to a desired optional ratio by a straight polarity/opposite polarity time ratio adjusting circuit 5. This signal is amplified to a value which can drive an inverter, by a pre-amplifying circuit 4 for an inverter circuit 3, and applied to each transistor 11-14 in the circuit 3. In this state, when one pair 11, 14 or 12, 13 of them has been cut off, a current flows by a small charge which has remained in the transistors. A short circuit between each transistor at that time is prevented by a control circuit 7. Thereafter, the other pair of transistors are conducted electrically at the same time, cut off after a prescribed time, the electric conduction is repeated alternately without being short-circuited as mentioned above, and a DC which has been obtained from a transformer 1 having a high no-load voltage and a rectifying circuit 2 is outputted as an AC square wave. This square wave becomes a plasma arc flame between an electrode 8 in a nozzle 9 and a base material 10.

Title: Automatic control method for sheet thickness
Inventor: KITANO SHINICHI
IPC: B21B27/02
Filed: 1986-11-11
Abstract: PURPOSE:To improve the responsiveness of monitor control and to minimize an off gage length by increasing the gain of proportional control and decreasing the gain of integral control with an increase in the deviation of a sheet thickness according to the magnitude of said deviation.

Title: Inclination displacement detector
Inventor: TSUDA NOBUO
IPC: G01C9/06
Filed: 1984-12-19
Abstract: PURPOSE:To detect multi-direction inclination displacement amount, by installing a plurality of pendulum plates and 1st and 2nd light-detecting means which receive light reflected on the top surface of the pendulum plate in a housing. CONSTITUTION:A pendulum plate 2 maintains its horizontal position always under effect of the gravity. Consequently, an inclined position of a housing 1 changes relative position of the housing 1 to the plate 2. By the change of the relative position, beams of light from photo-reflectors 3, 4, 1st and 2nd light-detecting means, intersect a plurality of reflecting fringes formed top and bottom of the plate 2 respectively, and consequently, beams of reflected light from top and bottom surfaces of the pendulum plate 2 are changed intermittently. The plurality of reflecting fringes formed on top and bottom surfaces of the pendulum plates 2 are so oriented to intersect each other that, the intermittent changes of the reflected beams from top and bottom of the plate 2 are proportional to each direction. Accordingly, by counting number of intermittent changes of each reflected beam, the inclination displacement amount of the housing can be obtained from the composite value of the frequency of the intermittent changes.

Title: Object detector
Inventor: KAWAMOTO YUICHI
IPC: G08G1/14
Filed: 1992-10-07
Abstract: PURPOSE:To reduce erroneous functioning and make setting easy by providing a means for measuring the distance to an object to be detected from the incidence angle of reflection light to a light receiver part and detecting the existence or pass of the object when the measured distance becomes closer than the distance to the background. CONSTITUTION:By intermittently emitting pulse signals with a timing controller 2, an LED drive circuit 3 is driven and infrared light is irradiated from an infrared LED to an object to be detected through a casting lens 8. The reflection light having passed through a receiver lens 6 is received with a PSD (position sensing element) and after amplifying 8, the distance is calculated 9 and compared with the distance to the background with a distance comparator 10. If the distance to the detected body is closer, existence or passing of the object is detected. By amplifying 11 and comparing 12 the received light, the existence of the object is detected when the reflection light is below a certain level for the received light. By this method using infrared beam, interference with other light is avoided and the part to be detected can be exactly set owing to a narrow detection area.

IPC: G01N29/06
Filed: 1987-10-27
Abstract: PURPOSE:To easily confirm the focus position of an acoustic lens to a sample from the position relation of a spot on the sample by providing light on at least two samples orthogonally to each other. CONSTITUTION:When the distance between the acoustic lens 1 and a sample 7 is longer than the focal length of the acoustic lens, two light spots of light beams 9-1 and 9-2 are formed on the sample 7 at an interval.

CONSTITUTION:If a fault response is sent back when a disk allocating means 36 requests a processing object disk device 32 to make preparations by referring to an ID control table 38 at the time of receiving a processing request from a host device 18, an allocation altering means 42 substitutes the physical ID of a disk device currently as a standby machine for the physical ID of the faulty disk device in the ID control table 38 and allocates the stand-by disk device instead of the faulty disk device. If there is an access request from the host device 18 during data restoration after the allocation, a requested address pointer is compared with the address pointer of the data restoration area and when the area is already restored, a reading or writing processing by an access processing means 40 is allowed.

Title: Vapor growth device
Inventor: KUBOTA HIROYA
IPC: H01L21/205
Filed: 1990-10-08
Abstract: PURPOSE:To prevent contamination of a piping by making an evacuation switching valve adjacent to a raw gas supply valve, by piping for the evacuation switching valve and by evacuating a piping alone between a stopping valve and the raw gas supply valve. CONSTITUTION:When a raw material containing container 1 is exchanged, a stopping valve 2 is closed, an evacuation switching valve 5 is opened and other valves such as an inject valve 8 and a vent valve 9 are closed. Remaining raw gas in a raw gas supply piping 3, especially between a raw gas supply valve 4 and the stopping valve 2 is removed by a vacuum pump 12 and air which entered when the container 1 is removed is eliminated. Returning from a vacuum state to a normal pressure is carried out by closing an evacuation switching valve 5 and by opening a purge valve 14 to supply inert gas. Contamination of a piping used during vapor growth is prevented in this way, thereby enabling good vapor growth.

Title: Driving circuit of ccd image sensor
Inventor: IWAZAWA MINEO
IPC: H04N5/335
Filed: 1984-12-21
Abstract: PURPOSE:To reduce an influence for picture signals due to noise superimposed by reset pulse and improve an S/N ratio by controlling the reset pulse amplitude which is applied to the CCD image sensor through reverse-amplified output of the difference between standard voltage and DC voltage proportional to the reset pulse amplitude. CONSTITUTION:When the reset pulse amplitude amplitude which is sent to the CCD image sensor varies and becomes less than a prescribed value, an output voltage of detecting circuit 13 is lowered and the difference between the output voltage of the detecting circuit 13 and the output voltage of DC electric power source is increased, resulting in increasing the output voltage of an error amplifier 14. Consequently, the voltage which is applied to a pulse amplitude control terminal 12a of pulse circuit 12 is increased, an output pulse amplitude of the circuit 12 is enlarged, and the decrease of reset pulse amplitude is compensated. Also, when the reset pulse amplitude is increased, the same compensating operation is made. Thus a negative feedback loop, i.e. detecting circuit 13   error amplifier 14   pulse circuit 12   detecting circuit 13, stabilizes the reset pulse amplitude to reduce the influence of noise superimposed by reset pulse.
