Title: Numerical controller for punch press
Inventor: TAJIMA YOSHIKAZU
IPC: G05B19/18
Filed: 1986-05-14
Abstract: PURPOSE:To work a curve with a single die by rotating the die and to reduce the kind of dies, by composing the die slope line control part of a numerical control device by a work starting point calculation part and the work pitch calculation part calculating the moving amount of X axis, Y axis and C axis of the 2nd time and after. CONSTITUTION:The moving amount X1 and Y1 of the X axis and Y axis to the working start point P1 located on the periphery and the initial time die turning angle thetac are found by a formula with the working start position designating angle theta1 of the working definition data, a die fitting angle theta3 and the radius R of the circle at a working start point calculation part 201. At the working pitch calculation part 202 the moving amount Xp and Yp of the X axis and Y axis of the working point Pk of the 2nd time and after and the moving amount Cp of C axis are found by a formula with a working pitch angle theta2, working start position designating angle theta1, die fitting angle theta3 and working radius R. The turning angle thetac of the die at the working point Pk becomes equal to theta2 and the angle in the slope line direction making the center of the circular arc of the die maintains the die fitting angle theta3, and the curve can be worked with a single die.

Title: Resistance generating circuit layout
Inventor: BERG MICHAEL
IPC: H03H11/24
Filed: 1998-04-22
Abstract: PROBLEM TO BE SOLVED: Not only to enable a resistance generating circuit to operate linearly as much as possible but also to restrain a diode which operates like a capacitor from being formed in a bulk region by a method wherein a diode is prevented from being formed between the source and bulk region of a MOS transistor, and a direct current voltage is made to overlap additionally with a bulk signal. SOLUTION: The voltage of a second terminal of a circuit layout is applied, for instance, to the source electrode 4 of a first PMOS transistor 1. The voltage is amplified as high as a potential difference across the base-emitter junction of a PNP transistor and then supplied to the bulk electrode 11 of a first transistor. Therefore, signals identical to those of the source electrode 4 and amplified by a potential difference across the base-emitter diode junction of a PNP transistor in a means 10 are applied to the bulk electrode 11 of the first transistor 1. Therefore, even if signals outputted through a terminal 6 are changed, the potential difference is obtained between the source and bulk terminal of the first transistor 1, and a capacitive diode is stopped from being formed between the source electrode 4 and the bulk region.

Title: Manufacture of thin film transistor
Inventor: NAGAHIRO NORIO
IPC: H01L29/786
Filed: 1989-04-27
Abstract: PURPOSE:To prevent occurrence of a gap between a channel protection film and source and drain electrodes by a method wherein a method of anisotropic dry etching proceeding straight vertically is applied to the surface of the channel protection film with a resist film used as a mask, an overhanging part of the resist film is removed subsequently, a process of film formation for forming the source and drain electrodes is applied and then the resist film is removed. CONSTITUTION:An SiO2 film 4 is etched by applying a method of anisotropic dry etching having a straight-proceeding property, with a resist film 5 having a shape of an overhang used as a mask. During this process, not only the part of the SiO2 film 4 covered up with the resist film 5, but also the part thereof around said part shaded with the overhang is masked. Therefore it is formed in the shape of the peripheral edge part being exposed. Reactive ion etching being applied to the resist film 5 subsequently, the top part of the resist film 5 is removed thereby in a prescribed thickness and the overhang is removed. Next, an n<+>a-Si film 6 and a Ti film 7 are formed as a contact layer and a source-drain electrode film respectively and they are connected also on the exposed peripheral edge part of the SiO2 film 4. Accordingly, the end parts of a source electrode S and a drain electrode D overlap with the peripheral edge part of the SiO2 film 4 and no gap takes place between them.

Title: Half-tone display system and half-tone display controller
Inventor: TAKASHI TERUMI
IPC: G09G3/36
Filed: 1989-04-28
Abstract: PURPOSE:To make a flicker due to frame-by-frame display ON-OFF operation inconspicuous even when a half-tone display is made by making groups of N color picture elements, e.g. R picture elements, G picture elements, and B picture elements different in thinning-out phase. CONSTITUTION:For example, a display control circuit 21 outputs the state of an R half-tone signal 251, which becomes 'high' when a frame counted value is '0', as R liquid crystal display data 221, the state of a G half-tone signal 252, which becomes 'high' when '2', as G liquid crystal display data 222, and the state of a B half-tone signal 253, which becomes 'high' when '1', as B liquid crystal display data 223. Thus, the respective picture elements are made different in the phase of the ON-OFF pattern of continuous ON-OFF control or made different in the ON-OFF pattern itself. Consequently, plural picture elements never become completely coincident in ON-OFF timing at the time of the half-tone display, and consequently the flickering of the display is reducible eventually.

A circuit breaker with good breaking function and low heat generation is thus obtained.

Abstract: PURPOSE:To secure a selection of the modulating carrier to the n and n+1 times as much as conventional by adopting the 2-step modulation system to the 1st and 3rd supergroup translations, thus miniaturizing each filter. CONSTITUTION:Basic supergroup p of 312-552kHz receives modulation at 1st modilator 9 and via 1st carrier wave nci which is obtained by giving n multiplication to carrier ci through multiplication circuit 17. And only upper side band wave nci+p is selected through filter 10a to be sent to 2nd modulator 11, where the modulation is given to wave nic+p sent for filter 10 via 2nd carrier (n+1)ci to send out the modulated wave to filter 12. Thus only the lower side band is selected through filter 12 to feature the same frequency band as conventional owing to (n+1)ci- (nci+p)=ci-p. The demodulation is carried out via filters 13 and 16, demodulators 14 and 15, etc. As a result, the filter can be miniaturized, realizing a highly economical system comstitution.

Title: Curl corrector for copying machine supplied with rolled paper
Inventor: KITAMURA TOSHIYUKI
IPC: G03B27/14
Filed: 1983-06-22
Abstract: PURPOSE:To perform an appropriate curl correction, by reducing the angle of unwinding of paper from a roll depending on the decrease in the diameter of the roll to heighten an unwinding effect. CONSTITUTION:When paper feed rollers 4 are rotating, a solenoid 24 is energized by a control section to swing a lever 21 clockwise to bring a curl correction roller 22 into contact with a roll of paper 1. The paper is delivered out of the roll while being in contact with the peripheral surface of the curl correction roller 22 within an angle theta, so that the paper is curled oppositely to its original curl. As a result, the curl of the paper is corrected. Although the diameter of the roll of the paper 1 is decreasing, the solenoid 24 is kept energized to bring the curl correction roller 22 into contact with the unwound paper in opposition to a spring 26. The curl of the paper is thus corrected depending on the decrease in the diameter of the roll.
