Title: Led drive circuit
Inventor: DANKI RIYOUICHI
IPC: H01L33/00
Filed: 1987-10-23
Abstract: PURPOSE:To obtain a drive circuit which is able to maintain an LED constant in a lighting intensity independently of the impedance of a connecting line and the variation of a power voltage by a method wherein a constant current source which is made to be ON/OFF based an LED drive signal and makes a current, which flows through an LED from a power source, constant in connected with the LED in series. CONSTITUTION:A constant current source 2 which is made to be on/off depending on a drive signal and makes a current IL, which flows through the LED 1 from a power source Vcc, constant is provided. For example, the constant current source 2 is made to be composed of transistors Q1 and Q2 and resistors R1, R2, and RE as shown in the figure. By these processes, when an LED drive signal which is to be inputted into a base of the transistor Q1 is at an 'H' level, the transistor Q1 is made to be on and the base of the transistor Q2 is made to drop to the ground potential, so that a current does not flow through the transistor Q2 and therefore the LED 1 is not lighted. And, when the LED drive signal is made to be at an L level, the base potential VB of the transistor Q2 is made equal to the potential of a partial voltage point A. Therefore, an emitter potential VE of the transistor Q2 satisfies the equation, VE=VB-VBE, and a collector current Ic is made to be constant.

Title: Method and device for controlling injection of chemical solution in package treating machine
Inventor: YAMADA KAZUO
IPC: D06B3/36
Filed: 1993-10-27
Abstract: PURPOSE:To eliminate defective treatments in a dyeing process, etc., by controlling the number of rotations of a chemical solution-injecting pump in response to a treating solution-circulating time expressed by (the volume of a treating solution)/(the volume of a circulated treating solution flow). CONSTITUTION:A chemical solution-injecting process is divided into plural steps, and the circulation number of the treating solution and the injection volume of the chemical solution are determined for each step to form a pattern, and the pattern is memorized in a setting unit 7. At the starting time of the first step, namely at the injection starting time, a treating solution volume measured with a treating solution-detecting means 5 and a circulation flow volume measured with a circulation flow volume-detecting means 6 are read. An arithmetic unit 8 computes the frequency of an inverter 9 from the measured value and the set pattern value to determine the number of rotations of an injection pump 11. The chemical solution in a chemical solution tank 12 is injected in response to a prescribed pattern.

Title: Stereoscopic television
Inventor: FUJII MUNEAKI
IPC: G03B35/16
Filed: 1990-10-08
Abstract: PURPOSE:To obtain a natural stereoscopic picture by displaying a video signal to be outputted while changing for each one field on a monitor and observing through right and left light transparent bodies where transmissivity changes alternately. CONSTITUTION:When a field signal SF is at a high level, the light transmissive part on a left eye side becomes a transmissive state, and the right eye side becomes a light impermeable state. It is inversely related when the signal SF is at a low level. Thus, the natural stereoscopic picture can be obtained by observing the right and left picture displayed while switched for each one field on the screen of a monitor 2 through the right and left light transmissive bodies 31 and 32 of spectacles 3 where the transmissivity changes alternately synchronizing with the field.

Title: Superimposing device
Inventor: FUJINO TAKAO
IPC: H04N5/278
Filed: 1984-12-21
Abstract: PURPOSE:To superimpose the characters corresponding to the images of image signals by reading out the character information relative to the second position information and mixing them with the image signals when the primary position information image signal coincides with the second position information read from a storage medium. CONSTITUTION:A 16-bit primary position information which is fetched from the image signal inputted to a terminal 10 is sent to a terminal A of a comparator 22. When a ROM cartridge 5 is mounted, a text ROM is accessed by address signals which are sent from an up-down counter 40 and a decoder 51, while a 16-bit position information read out from a text ROM23 is latched by 8 bits in latch circuits 42, 43 and is sent to a terminal B of the comparator 22. The comparator 22 compares both position information, generates control signals to send to a clock control circuit 39, and drives the up-down counter 40. Thus this makes the read-out address of the ROM23 variable so that its position information may be coincident with the position information of the image signals, and then a flip-flop 44 is set when both position information become coincident.

Title: Measuring method for paper transport amount
Inventor: HARUYAMA KOJI
IPC: G01B21/06
Filed: 1999-09-24
Abstract: PROBLEM TO BE SOLVED: To provide a measuring method for transport amount for properly and effectively measuring the paper feed accuracy. SOLUTION: In this paper transport amount measuring method in a printer, while a paper sheet on which a measurement pattern is printed by designated print pitch is fed in a inspection object printer 100, the measurement pattern is measured, and the obtained measurement value is corrected by reference measurement data to measure the paper feed amount. In creating a paper sheet where a measurement pattern is printed, to print a measurement pattern while the paper sheet is fed by measured pitch, the moving amount of the paper sheet is used as a correction value to measure the printer pattern position. Thus, the paper transport amount can be measured without the factor of a print head, so as to improve the accuracy of measuring the paper feed.

Filed: 1986-11-13
Abstract: PURPOSE:To obtain a signal of a prescribed level regardless of fluctuation of power voltage or temperature by providing a phase difference discrimination circuit, a pulse width generating circuit and a discrimination circuit and adopting the constitution such that an output of the phase difference discrimination circuit and an output of the pulse width generating circuit are compared digitally. CONSTITUTION:When a PLL is in unlock state and a pulse width of a phase difference discrimination signal (d) is wider than the pulse width of an output signal (f) of the pulse width generating circuit 16, an output of either D flip-flop 19 or 20 goes to an H level, an output of an OR circuit 21, that is, an unlock signal output 23 has a signal of H level. Then when the PLL is locked completely, the pulse width of the phase difference discrimination signal 13 is smaller than the pulse width of the output signal 17 of the pulse width generating circuit 16. Thus, in the lock state, the output of both the D flip-flops 19, 20 of the discrimination circuit 18 goes to L level and the unlock output signal is obtained as an L level signal.

Title: Reduction of contour generation of low intensity and color moving by means of dither
Inventor: GUREGORII ESU PETEITSUTO
IPC: G09G3/20
Filed: 1996-10-14
Abstract: PROBLEM TO BE SOLVED: To reduce a visible artificial object such as a pseudo contour and color moving which are generated by a quantization error without cost-up in a digital display. SOLUTION: This method reducing the influence of pseudo contour generation and reducing a color gradation artificial object adds a small noise signal from a noise generator so as to make an image signal (102) dither. As the added noise signal breaks the edge of the block of uniform pixels, a generated image looks as if moving from one area to a next area. When the quantization error is caused at the time of processing the chrominance part of the image signal and similar gradation sharply moves though an input signal moves smoothly, the dither of the image is especially useful.
