Title: Production of stamper for optical disk
Inventor: TAKEI SHOTARO
IPC: G11B7/26
Filed: 1986-10-22
Abstract: PURPOSE:To improve the adhesive power of a conductibilized film and Ni plating by immersing a glass substrate with a pregrooved pattern formed with the conductibilized film into an Ni plating liquid, rotating the same and subjecting the substrate to a reverse electrolytic treatment with a specific negative voltage. CONSTITUTION:A resist film 2 is formed by spin coating method using a photoresist on the glass substrate 1 the surface of which is polished to a flat surface and is kept clean. The film is then dried by heating. Information recording is executed on the film by a laser cutting machine and the film is dried after development to form pregrooves 3. Ni is sputtered to a prescribed thickness on the surface of such substrate 1 to form the conductibilized film 4. The substrate 1 is then immersed in the Ni plating liquid and is rotated; thereafter, the conductibilized film 4 as an anode is electrolyzed at 0.1-0.3V to remove the oxide films and stains of the film 4 and to improve the wettability. Ni plating is executed immediately thereafter to form a plating layer 5; further the plated surface is polished, by which a stamper 6 is obtd.

IPC: H04B10/60
Filed: 1995-09-29
Abstract: PROBLEM TO BE SOLVED: To reduce distortion and noise characteristics by controlling the gain of an electric signal converted from a light receiving element, outputting it, extracting only distortion and noise components from the output and canceling the distortion and noise components by amplifying them. SOLUTION: An optical signal is converted into an electric signal by a light receiving element 1 and branched by a brancher 2 and one signal is amplified by a variable gain amplifier 3, branched by a brancher 4 and outputted through a 1st delay circuit 5 and a synthesizer 10. The signal branched by the brancher 4 is attenuated just for the gain component of the amplifier 3 by an attenuator 6. The signal branched by the brancher 2 is converted into the signal having the reverse phase of an output signal from the attenuator 6 by operating a delay circuit 7 and at the output of a synthesizer 8, only the error signal generated at the amplifier 3 is outputted. That error component is amplified just for the gain of the amplifier 3 by a variable gain error amplifier 9 and synthesized with the signal from the amplifier 3 by the synthesizer 10.  Thus, the signal having no error component at the output is outputted.

Title: Bus right request circuit
Inventor: ITO MASAHIRO
IPC: G06F13/37
Filed: 1988-10-07
Abstract: PURPOSE:To enable even a low-level bus master to acquire the bus right within a constant time without fail by starting a timer by a requester when a bus right request is generated, and inhibiting a bus use premit signal of different level from being transmitted by a transmission inhibiting means and outputting a bus right acquisition signal at the same time when the timer counts up. CONSTITUTION:When a transmission signal BGINH'L' of level for a next bus master is inputted from a bus arbiter side, a gate circuit G1 is closed by a flip-flop circuit FF which is reset with the output 'H' of the timer 32 and signal transmission to a downstream-side bus master is inhibited with a transmission signal BGON'H'. On the other hand, a gate circuit G2 sends an output with the Q terminal output of the flip-flop FF and the sent signal is supplied to the terminal BGI of the requester 31 through a gate circuit G3 without reference to the signal BGINL'H', so that the requester 31 outputs a signal BBSY'L' as the bus right acquisition signal. Consequently, even the low-level bus master can use a bus after a fixed time.

Abstract: PURPOSE:To sufficiently correspond to high speed printing without using a CPU or an LSI by setting the current supply cycle time corresponding to a plurality of dots to one unit time of a current supply output processing based on the operational processing result of a current supply time within said current supply cycle time. CONSTITUTION:When high speed printing is performed, a current supply cycle time B wherein a current supply cycle time A of each dot is used in the quantity corresponding to a plurality of dots, for example, two dots is set to one unit time of a current supply control time.

The driving of a drive motor is controlled so as to drive a carriage by 22 dots. Since control is performed so that the current supply cycle time corresponding to two dots is set to the time B twofold the conventional time A, a printing speed can be made substantially twofold.

Title: Liquid crystal display device
Inventor: WATANABE MASAKATSU
IPC: H01L29/786
Filed: 1997-09-18
Abstract: PROBLEM TO BE SOLVED: To enable the discharge of the charges of pixels and storage capacitors to signal lines and to prevent the generation of after-images by the residual changes by maintaining switching elements for driving at a conducting state even at the time of non-operation when a power source is held turned off. SOLUTION: The pixel voltages charged and discharged into and from the liquid crystal display pixels 5 and the storage capacitors 7 are held by the effect of the storage capacitors 7. The scanning line voltages change the potential by leakage and rapidly shift to a voltage VB (the potential at the time of the non-operating state as a driving circuit) after the power source of the system is turned off and the scanning line voltages are no more controlled. As a result, the switching elements 6 attain the state that the voltage VB is held applied on their gates. The charges in the capacitors 7 are discharged via the elements 6 to the signal lines 3. Then, the discharges of the pixel voltages flow through discharge routes to the signal lines 3 and are, therefore, eventually rapidly discharged and the after-images in the case the power source of the system is turned off are eliminated.
