Title: Laser speedometer
Inventor: HANAWA YUJI
IPC: G01C19/00
Filed: 1985-03-27
Abstract: PURPOSE:To directly detect a speed, by utilizing such a phenomenon that the difference is generated between the propagation light paths of laser beams propagating to reverse directions when a speedometer has a speed to an inertia space and the phase difference between both lights at light detection points are changed by a beam splitter. CONSTITUTION:When the inertia speed of a laser speedometer 10 is zero, the difference between the beam paths of CW beam 8 and CCW beam 9 from a beam splitter 3 to a beam splitter 5 is constant and the interference degrees of both beams in the beam splitter 5 do not change. If the inertia speed of the laser speedometer 10 takes a value other than zero, the difference between the beam paths of CW beam 8 and CCW beam 9 are shifted from a definite value and, as a result, the interference degrees of both beams in the beam splitter 5 also change. Because the change quantities of said interference degrees are proportional to the inertia speed, if the change quantities of the interference degrees are detected by a beam detector 7, the inertia speed of the laser speedometer 10 can be detected.

Title: Power-on reset circuit
Inventor: SAITO TADAHIRO
IPC: H03K17/22
Filed: 1985-03-27
Abstract: PURPOSE:To generate a reset signal even when the leading of a power supply is slow by connecting an element which is turned on and then causes a prescribed voltage drop with a power supply rising to a voltage and a capacitor generating a reset signal in series between power supplies. CONSTITUTION:A MOS transistor (TR) Q5 turned on when the power supply rises to a voltage and causing a prescribed voltage drop further, a resistor R and a capacitor C are connected in series between power supplies. When a power supply voltage Vcc reaches the threshold value Vth of the TR Q5 at application of power, the TR Q5 is turned on and the capacitor C is charged through the resistor R. When a voltage VA exceeds the threshold voltage of an inverter I1, a TR Q1 is turned off, a TR Q2 is turned on and a voltage VB goes to an L level, then a TR Q3 is turned on, a TR Q4 is turned off and a voltage Vc at an output terminal C goes to an H level in an inverter I2, but the voltage Vc is at L level until that time and the voltage Vc being at an L level becomes a reset signal.

IPC: C21D9/50
Filed: 1981-04-25
Abstract: PURPOSE:To enhance the toughness of a weld metal by reducing the reinforcement of the weld metal at a specified surface temp. and a specified reduction ratio. CONSTITUTION:The reinforcement of a weld metal is cooled or reheated and reduced by >=10% of the height at a surface temp. just above the Ar3 transformation point to the Ar1 transformation point. The reduced reinforcement is cooled as it is, or it is further subjected to hardening, tempering or normalizing. By said reduction the influence of dendrite is almost eliminated, and the toughness is enhanced. By increasing the reduction ratio, the breaking of dendrite proceeds. When the reduction ratio is 10% or slightly above 10%, it is effective to carry out the reduction by 1 pass.

Abstract: PURPOSE:To eliminate a bad influence on a charge transfer device by a signal leaked from a circuit means in a periphery by a method wherein a means to electrically separate the charge transfer device and the circuit means is installed in a semiconductor main body. CONSTITUTION:A p-type epitaxial layer 3 is formed on a p-type silicon substrate 1 where a high-concentration n<+> type buried layer 2 has been formed; a high- concentration n<+> type diffusion layer 4 is formed inside the p-type epitaxial layer 3 so as to come into contact with the high-concentration n<+> type buried layer 2; an n-channel type CCD(charge-coupled device) is formed. The high- concentration n<+> type diffusion layer 4 and the high-concentration n<+> type buried layer 2 coming into contract with it are biased to, e.g. a Vss.

Title: Optical integrated circuit
Inventor: HORI YOSHIKAZU
IPC: G02B6/122
Filed: 1987-03-18
Abstract: PURPOSE:To emit a complete parallel beam out by structuring part of a two-dimensional optical waveguide formed on a plane substrate so that plural single- mode three-dimensional optical waveguides where light is confined laterally adjoin one another at constant intervals, and coupling the respective single-mode optical waveguides optically. CONSTITUTION:Projection light from a semiconductor laser 6 is guided into a waveguide layer 3 by end surface coupling and propagated while spreading. The light is converted by a Fresnel lens 4 made of SiN4 into nearly collimated light, which is coupled with plural single-mode waveguides made of SiN5. The direction of the light propagated in the single-mode waveguide part 5 is completely equal to the stripes of respective single-mode waveguides, so the light is propagated as complete collimated light. Further, periodic variation in effective refractive index is formed on the surface of the single-mode waveguide 5 made of a loading layer to an about 300Angstrom  depth, and consequently the propagated light is emitted out. The emitted light is converged by an optical lens nearly to a diffraction limit and a complete parallel beam is formed.

Abstract: PURPOSE:To prevent the creeping of the photoresist to the back surface of a water, by forming the back surface of a sucking surface into a curved or inclined surface and providing a nozzle blowing out gas in parallel to the rotary shaft of the suction stand in a concentric circular state. CONSTITUTION:A wafer 2 is placed on the sucking surface of a vacuum suction stand 1 and sucked under vacuum through a vacuum suction hole 1e.

Title: Power supply unit for piezoelectric actuator drive
Inventor: ISHIKAWA HIROYUKI
IPC: H02N2/00
Filed: 1997-03-17
Abstract: PROBLEM TO BE SOLVED: To provide a piezoelectric actuator drive power supply unit which can output an inclined wave having a prescribed inclination based on a rectangular wave signal inputted from a host computer. SOLUTION: When a control rectangular wave signal V1 inputted in an operational amplifier 9 rises steeply, current I runs from the output side of the operational amplifier 9, so that a capacitor 11 is charged, and a signal V2 is outputted from an output part 12 according to the voltage across the terminal of the capacitor 11. At this time, the current I has a constant value IO by a constant current circuit 10, therefore, the voltage across the terminal of the capacitor 11 is proportional to the time and increases linearly. When the potential of one end part A is equal to that on the output side of the operational amplifier 9, the current I is zero, and the signal V2 outputted from the output part 12 maintains a voltage value obtained at that time.

Title: Apparatus for marking back of trial print
Inventor: JIYORUJIYU RORE
IPC: G03B27/52
Filed: 1988-03-18
Abstract: An apparatus for marking the back of a photographic proof with data corresponding to data on the corresponding negatives in a system where the negatives are on a film strip having at each negative an edge notch and the proofs are on a print strip having spaced cutouts comprises a film drive for advancing same from the upstream to the downstream drive roll past a read location. A sensor detects the film-advance speed and generates an output corresponding thereto. A print drive advances this strip past a write location. Another sensor detects the paper-advance speed and generates an output corresponding thereto. A controller is connected to at least one of the drives and to the sensors for synchronizing displacement of the strips past the respective locations such that each proof is at the write location generally when the respective negative is at the read location. Another detector generates an output each time a notch is in a predetermined position at the read location. Another read head at the read location triggered through the controller by the notch detector each time the exposure data of the respective negative is in the read location reads this data. Another detector generates an output each time a cutout is in a predetermined position at the write location. A write head at the write location triggered through the controller by the cutout detector each time the print is aligned with the write head marks the back of the print strip with the exposure data read by the read head on the respective negative.
