Title: Original plate for planographic printing plate
Inventor: OKAMOTO YASUO
IPC: G03F7/00
Filed: 1999-09-03
Abstract: PROBLEM TO BE SOLVED: To obtain a planographic printing plate having sufficient sensitivity and image strength and excellent in printing durability and particularly small dot reproducibility by using a polyvinyl acetal having an alkali-soluble group as a binder component of a photopolymerization layer. SOLUTION: The planographic printing plate has a photopolymerizaiton layer containing a polyvinyl acetal having an alkali-soluble group, an addiiton polymerizable monomer and a photopolymerization initiator. The solubility to alkali at the time of developing is suppressed and as a result, the photopolymerization layer is hardly affected by the external force due to the contact with a blanket cylinder or the like at the time of printing by containing the polyvinyl acetal having the alkali soluble group as the binder component of the photopolymerization layer to cause the interaction of the polyvinyl acetal with the addition polymerization monomer and supporting body in this way.  As a result, the original plate of the planographic printing plate excellent in printing durability and particularly the small dot reproducbility (highlight characteristic) is obtained by having sufficient sensitivity and excellent image strength.

Title: Differential amplifier
Inventor: SEKI SHOHEI
IPC: H01L29/78
Filed: 1986-10-23
Abstract: PURPOSE:To improve the symmetricity of a differential amplifier characteristic by adopting the constitution such that FETs constituting differential pair transistors (TRs) of the titled differential amplifier are formed by two FETs connected in parallel and arranged in a way that the source/drain current flows in opposite directions to each other thereby suppressing the fluctuation of the characteristic of the FETs caused by the mis-alignment of the mask pattern. CONSTITUTION:The two FETs Q1, Q2 are constituted by the parallel connection such that a gate electrode 22 and a source electrode 21 are arranged symmetrically to the light/left around each drain electrode 23 so that directions of the source/drain current are opposite to each other. If the arrangement of the gate electrode 22 is slightly shifted right from the correct position, a series resistor between the source electrode 21 and the gate electrode 22 of the FET Q1 is increased and the gate-source capacitance is reduced. Moreover, the series resistance between the source electrode 21 of the FET Q1 and the gate electrode 22 of the FET Q1 is decreased and the gate-source capacitance is increased to cancel the change in the characteristic of the left half FET. Thus, the fluctuation of the entire FET Q1 due to the deviation of the gate-source series resistance and capacitance caused by the deviation of the gate electrode is reduced.

CONSTITUTION:When a power supply line 6 is impressed with voltage in the initial phase of an operation, a gate potential 7 is boosted through a capacitor 1 to turn an MOSFET4 ON supplying the FET4 and a resistor 5 with power for heating a substrate.

Filed: 1984-11-28
Abstract: PURPOSE:To stabilize tracking control by recording an index signal to a common position of each tracking detection track and using three independent laser beams to trace both tracking tracks at both sides of the information recording track. CONSTITUTION:Tracking detection tracks 10, 11 are provided between information recording track regions 7, tracking detection signals f1, f2 are recorded alternately at each period and an index signal f3 is recorded to a position in common to each tracking detection track.

IPC: H04N5/91
Filed: 1987-10-05
Abstract: PURPOSE:To prevent the degradation of the phase characteristic of a reproducing pilot signal by a noise at a reproducing time by executing the multiple recording of the reproducing pilot signal of large amplitude, whose rising and falling are sharp, in a PCM sound data multiplexing period to have a large noise component. CONSTITUTION:A control pulse generating circuit 4, which generates a control pulse in a vertical blanking period or the PCM sound multiplexing period, and a signal level emphasizing circuit 10, which synchronizes to this control pulse and emphasizes the level of a pilot signal, are added to a conventional video disk recorder. Accordingly, the level of the pilot signal, which is multiplexed in the vertical blanking period or the PCM sound multiplexing period, is emphasized. Thus, without degrading the SN ratio of reproducing PCM sound data, the level of a second lower side band component to be mixed to the reproducing pilot signal can be relatively suppressed.

Abstract: PROBLEM TO BE SOLVED: To prevent a reheating circulating port from becoming a hindrance when a bather sits down on a seat part, and improve the safety so that boiling water does not splash on the bather even if a bath is reheated, by forming a recessed part in the front part of the seat part, and arranging a reheating circulating port and a discharge port so as to be positioned in this recessed part. SOLUTION: The seat part 2 is formed in one end part inside a bathtub 1, and in this seat part 2, a recessed part 2a is formed in the central part of a front wall. A reheating circulating port 4 is arranged in a bottom surface of this recessed part 2a, and a waste port 5 is arranged in a place sandwiched by both side surfaces of the recessed part 2a. That is, the reheating circulating port 4 and the waste port 5 are housed inside the recessed part 2a.

Title: Rom access system
Inventor: IKEZAWA MASUYUKI
IPC: G06F9/30
Filed: 1984-11-29
Abstract: PURPOSE:To make the programming speed higher without damaging the adaptability of programs, by providing a read-only memory equipped with two port outputs for reading out instructions and coefficient data. CONSTITUTION:Instructions to a digital signal processor (DSP) are read out from an ROM 8 storing instructions and coefficient data in accordance with addresses given from a program counter 3 in the DSP. After the instructions are once stored in an instruction register 4, addresses of coefficient data, etc., necessary for executing the instructions are given to the ROM 8 and the instructions are executed in accordance with the obtained coefficient data 10. Since the ROM 8 has two port outputs, parallel readout of coefficient data for the currently executed instruction and the next instruction word itself can be performed and, as a result, a high speed can be maintained. Moreover, since it is not necessary to separate instruction words from coefficient data, the adaptability of the programming is also high.
