IPC: G02F1/133
Filed: 1991-09-09
Abstract: PURPOSE:To enable drawing an uniform line width over a whole screen by varying the laser peak power of a laser diode in accordance with a plotting position. CONSTITUTION:When laser beams from the laser diode 30 are scanned on the surface of a liquid crystal cell 7 and a graphic, etc., with a specified line width is drawn, a position adjusting means 61 making reference voltage supplied to the laser diode 30 vary in accordance with the position drawing on the liquid crystal element is provided. Namely an X axis positioning signal Vx supplied to the input of a first absolute- value circuit 62 is selected so as to be a maximum voltage level at the left edge and the right edge of the display region of the liquid cell 7 and also a Y axis positioning signal Vy supplied to the input of a second absolute value circuit 63 is selected so as to be a maximum voltage level at the upper edge and the lower edge of the same display region. A voltage with a specified level waveform added to the first and the second absolute value circuits 62, 63, and an adder circuit 64 is allowed to be a reference voltage compensating the voltage at the peripheral part compared with the central part, with variable resistors VR1-VR3 by the classification of the line of a reference voltage setting circuit 52. Thus, the drawing with a constant line width is attained.

Filed: 1994-09-26
Abstract: PURPOSE: To maintain a polishing effect for long, to increase the polishing area of a discharge wire, to lessen the imperfect rubbing of the circumference at the cross section of the discharge wire and to prolong the service life of a cleaning member by forming the cleaning member of a foam dispersed with polishing agents over the entire part. CONSTITUTION: Cleaning pads 45, 46 are obtd. by dispersing the foamed polyurethane polishing agents and subjecting these polishing agents to a foaming treatment. The surface of the pad 45 is cut off by a wire 2a and the form near the entire periphery of the wire 2a is embedded into the pad 45 after repetition of cleaning.

Title: Guide apparatus for attraction type magnetic levitation car
Inventor: YAMAGUCHI HITOSHI
IPC: B60L13/04
Filed: 1988-09-13
Abstract: PURPOSE:To make the title car pass on the curve of a track having a small radius of curvature, and to obtain a guide apparatus having small excitation loss from a viewpoint of overall line length by installing a guide electromagnet to a truck through a hydraulically controlled moving plate as a clearance control means. CONSTITUTION:The spring energizing force of a compression spring 18 and magnetic attraction force working between a guide electromagnet 3 and a guide magnetic rail 6 are applied to a moving plate 14, and the moving plate 14 travels on the rectilinear section of a track while holding minimum void length Gmm regulated by a stopper 16A. When a hydraulic pump is driven before the title car approaches to a curve and a hydraulic system 12 is driven to the anti-track side, void length G is extended. Consequently, a marker on the track 4 is read or the output signal of an oscillator, etc., on the track is received, thus controlling the hydraulic pump. Accordingly, void length G can be expanded in response to the radius of curvature of the curve only at the time of the passage of the curve.

Title: Manufacture of semiconductor device
Inventor: OMURO SHINGO
IPC: H01L21/3205
Filed: 1990-08-30
Abstract: PURPOSE:To prevent an increase in a contact resistance in a simple step and to improve reliability of an integrated circuit to be manufactured by heat treating a WSix layer and then forming a BPSG film by a CVD method. CONSTITUTION:A thin polycrystalline silicon film 4 is formed on a P-type diffused layer formed in a silicon substrate 1 and an insulting film 4 formed on the substrate, and then a WSix film 5 is formed. Thereafter, it is heat treated at 800 deg.C in an N2 atmosphere by RTA. Then, a BPSG film is deposited by a CVD device, and heat treated to conduct annealing and reflowing. Since diffusion of phosphorus is blocked by the WSix layer by densifying the WSix layer by heat treating, the phosphorus is not diffused to the contact boundary between the P-type diffused layer and the WSix wiring layer, and an increase in the contact resistance can be prevented.

Title: Method and device for measuring reflectance
Inventor: SEMURA SHIGERU
IPC: G01N21/55
Filed: 1990-08-31
Abstract: PURPOSE:To make measurement of the refractive index with the beam dia. condensed still thinner by allowing the light emitted by a light source to be incident to the object to be measured in such a way as perpendicular thereto and focusing in the neighborhood thereof, and by separating the reflected beam from the incident beam. CONSTITUTION:A laser beam emitted by a laser device 1 is put incident to a specimen 6 with the optical axis arranged perpendicular thereto and is condensed by a lens 3 which is adjustable so as to focus in the neighborhood of the specimen 6. The reflected beam reflected by the specimen 6 and advancing oppositely on the light path identical to the incident beam is separated from the incident beam by a beam splitter 2, and a photo-receiving device 5 measures the intensity. Because the optical axes of the incident and reflected beams become identical in the neighborhood of the specimen 6, the incident beam can be condensed to servo measuring the refractive index in a minute region. The lens 4 is adjustable so as to maximize the photo-receiving amount of the device 5, and thereby the reflected beam is condensed at the device 5. Accordingly the measurement can be done with the beam dia. condensed thin, wherein a high space analyzing capability is provided.

Title: Control circuit for solenoid of multistage power level type
Inventor: MAAKU KORUDEBERA
IPC: H01F7/18
Filed: 1991-09-10
Abstract: PURPOSE: To provide a control circuit for a solenoid actuator capable of working in both of a high power mode and a low power mode to prevent overheating and failure of a solenoid. CONSTITUTION: A player is furnished with a solenoid to generate high propulsive force at the time of closing a flipper switch. A primary power circuit is devised to reduce power and to send only low holding power at the time when the player closes the flipper switch longer than specified time. Thereafter, when a flipper starts moving from a holding, that is, static state, a sensor actuates a holding timer circuit and generates high propulsive force again. The holding timer circuit lowers power after another specified time passes. When the flipper starts slipping again, the holding timer circuit is reexcited and a cycle is repeated. When the player once releases the flipper switch, the solenoid is demagnetized, and both of the timer circuits are reset until the player presses the flipper switch again.

Also, the lower limit pressure P1 and the upper limit pressure P2 to the inside of the room 1 are set in advance, and by length of the time when the pressure has reached the upper limit value P2, and the time when it has reached the lower limit value P1, a degree of its leak is evaluated. In this regard, a measuring signal from the pressure gauge 12 is inputted to the recorder 14, and details of the time extending from a stage in which the pressure has reached the upper limit value P2, to a stage in which it has reached the lower limit value P1 are recorded. In this way, the airtight performance can be measured with a high accuracy.
