Title: Video printer
Inventor: YONEKUBO MASATOSHI
IPC: H04N9/79
Filed: 1982-12-28
Abstract: PURPOSE:To obtain an easy-to-see picture with less number of a quantized level by storing a data representing different imaging effect on plural lookup tables. CONSTITUTION:Data applied with the inverse gamma correction for a cathode ray tube, the correction of color distortion due to incomplete spectral characteristic of each color member by a masking matrix, the determination of amount of black print from a neutral color component and the elimination of underlay color of each member, and the correction of picture density characteristic to the modulation of an input signal are stored in a lookup tables 3. The three tables 3 output dark or bright data with fidelity to information of lightness of the input signal. When the desired table 3 is designated by using a switch 2, the video signal 1 is converted into a data of each color member and the amount of black imaging and transmitted to a full-color print mechanism 4 to control the amount of print of each ink.

Title: Gate control for electrostatic induction thyristor
Inventor: KAWAMURA YUTAKA
IPC: H01L29/74
Filed: 1984-11-07
Abstract: PURPOSE:To reduce switching loss at turn-off by using an output signal from an interrupting current detection means to control an off-gate current thereby controlling the current gain at turn-on to be a prescribed value. CONSTITUTION:An electrostatic induction (SI) SCR 1 is turned on by turning an FET 10 and using a control power source 11 to flow a current between the gate and cathode of the SCR 1. A voltage given between the gate and source of an FET 9 is set to 0 or negative to turn off the FET 9 by dividing the voltage being the sum of the power source 11 and an auxiliary power supply 8 with the voltage dividing ratio of resistors 13, 14. In turning off the SCR by turning off an FET 10, the interrupted current is detected by a current transformer 18, a voltage proportional to the turn-off current is generated across a resistor 16, the voltage is impressed to a gate of the FET 9 and an off-gate current is fed to the SCR1 from the power supply 8. A voltage across the resistor 15 is impressed between the cathode and gate of the SCR 1 as a reverse bias and the current gain is a constant value independently of the turn-off current.

Title: Liquid crystal display device
Inventor: SUMIYOSHI KEN
IPC: G09F9/35
Filed: 1990-09-05
Abstract: PURPOSE:To make a black display and to obtain improved visual dependency by laminating a optically positive liquid crystal layer which is oriented in parallel and an optical negative optical compensating layer which has an optical axis in an in-surface direction parallel to the parallel orientation direction on a substrate. CONSTITUTION:The optical axes of a homogeneous cell 101 wherein optically positive liquid crystal molecules are oriented in parallel and the optically negative optical compensating layer 102 are set parallel. When incident linear polarized light 103 which is polarized at 45 deg. to the optical axis is made incident, (x)-axial linear polarized light 104 (shown in figure) is delayed behind (y)-axial linear polarized light 105 in the homogeneous cell 101. The optical compensating layer 102, however, is optically negative, so the (x)-axial linear polarized light leads the (y)-axial linear polarized light. The phase speed in the optical axis direction is faster than the phase speed in a direction crossing it at right angles in an optically negative medium, so birefringence quantities of the both become zero and light wavelength dispersion is eliminated, so that the black display can be made.

Title: Digital/analog converter
Inventor: TANI YASUNORI
IPC: H03M3/02
Filed: 1999-08-23
Abstract: PROBLEM TO BE SOLVED: To effectively suppress the occurrence of harmonic distortion caused by the variation among the outputs of 1-bit digital/analog converters by inhibiting the appearance of harmonic distortion in the output of a 1-bit digital/ analog converter row. SOLUTION: Firstly, the digital input of a digital/analog converter is converted into a p-value digital signal by raising the sampling frequency by means of a digital filter 10 and a noise shaper 11. A decoder 12 assigns the output of the noise shaper 11 to (p-1) 1-bit signal strings so that the position of value '1' may go round, designates the position of an inhibit bit in the 1-bit signal strings and, when the assignment of '1' reaches the position of the inhibit bit, the tour of the assignment is promoted by avoiding the inhibit bit and the position of the inhibit bit is moved so that the assignment may make the tour to the next bit. Then the 1-bit signal strings are converted into analog signals by means of the uniform (p-1) 1-bit digital/analog converter rows 13 and the analog signals are integrated by means of an analog adder 14.

Abstract: PURPOSE:To prevent the occurrence of unevenness in cutting and weld through prevention of deformation of the tip part of an external nozzle and to perform safe cutting work by a method wherein the external nozzle of a blow pipe used when a metal is cut and welded is formed of ceramic. CONSTITUTION:A blow pipe comprises a nut 1 with a nozzle tip fastening, an external nozzle 2, an internal nozzle 3, and a nozzle drum body 4.

Abstract: PURPOSE:To sufficiently supply solder for improving soldering strength by performing cutting-in processing of various kinds on each terminal of the insertion type components for widening the surface area of terminal and widening a sticking area of each terminal of the insertion type component. CONSTITUTION:At the time of performing soldering by inserting an insertion type component 1 into a printed wiring board 2, solder 3 sticks in an angle shape having a terminal 5 of the insertion type component 1 as the top.

Filed: 1986-10-06
Abstract: PURPOSE:To extend the working voltage range of a voltage division circuit by connecting the power source terminal of a 1st voltage follower circuit between the positive electrode of a DC power source and an output from a 2nd voltage follower circuit and further connecting the power source terminal of the 2nd voltage follower circuit between an output from the 1st voltage follower circuit and the negative electrode of the DC power source. CONSTITUTION:Where the power source voltage of the 1st voltage follower circuit and that of the 2nd voltage follower circuit are E1 and E2, respectively, they come to 2/3E with resistance R1=R2=R3=R given. Hence a DC power source voltage more than the maximum absolute rated voltage of the voltage follower circuit (if R1=R2=R3=R holds, it is 1.5 times the maximum absolute rated voltage) can be divided by three. Since the electric loss of the voltage follower circuit, which is caused by the imbalance of a connected load, is distributed to the 1st and 2nd voltage follower circuits, the electric loss of each voltage follower circuit can be reduced.
