Title: Method for forming transparency image
Inventor: HIRANO YOSHIYUKI
IPC: B41M5/26
Filed: 1997-02-27
Abstract: PROBLEM TO BE SOLVED: To easily change an image pattern of a transparency image, by projecting laser light to a predetermined part of a sheet base face on the basis of image pattern information, partially removing the projected part so much as not to penetrate the sheet base, and forming an image in a half cut state to a sheet face. SOLUTION: In order to form a transparency image, an encoder is connected to a tractor device T to detect a feed amount of a continuous sheet W. A rotation amount of the tractor device T is converted to a pulse signal, thereby detecting the feed amount. When the encoder and an optical detection sensor D detect that a part of each unit sheet S where the transparency image is to be formed reaches a projection position by the laser light, a control part feeds a projection operation signal to a laser light oscillator L and sends a driving signal to a driving part of each polarizing mirror M. A pulse laser light corresponding to image pattern information of the transparency image is projected. A sheet base 1 of the projected part is partially removed in a half cut state, so that a transparency image 2 is formed.

Filed: 1986-03-18
Abstract: PURPOSE:To make easy a guide opening/closing operation by an operator, by providing a set mechanism for restoring an opened guide plate to a set position in association with a feeding operation. CONSTITUTION:When a guide 3 is rotated about a fulcrum 3a to be opened, the rotation of feeding rollers 2a-2d is stopped. The guide 3 is designed to be manually opened and maintained open by its tare. Under this condition, an operator may remove a jam paper or clean a guide surface. When the operator depresses a power switch or the like to restart the feeding operation, the feeding rollers 2a-2d are rotated. As a result, a cam 6a mounted on a shaft 20 of the feeding roller 2a is also rotated to contact an engagement portion 3b of the guide 3 and lift the engagement portion 3b. Accordingly, the guide 3 is rotated about the fulcrum 3a in a restoring direction, and is then restored to a set position by its tare.

Title: Generating device of false signal
Inventor: ISHII YASUYOSHI
IPC: G01S3/801
Filed: 1989-03-13
Abstract: PURPOSE:To simplify a circuitry by a method wherein pulse trains generated by an artificial random binary series generating circuit and a rectangular wave generating circuit are delayed for an arbitrary time by a shift register respectively. CONSTITUTION:A random series of random signals (digital signals) generated by an artificial random binary series generating circuit 1 becomes long sufficiently when the signals are passed through a wave-shaping circuit 8 and a low-pass filter 9, and it turns to be equivalent to random noise when a clock frequency is set to be high sufficiently. When a rectangular wave signal generated by a rectangular wave generating circuit 2 is passed through the wave-shaping circuit 8 and the low-pass filter 9, a spectral signal based on the period of a rectangular wave is obtained. These two kinds of digital signals are shifted by a shift register 4 respectively and added up by an addition circuit 7, they are made to wait thereafter for a necessary delay time in a sphere from CH1 to CHn, and false signals formed by superposition of the random noise and the spectral signal is generated. Since the shift register is used for delaying the signals, in this case, a signal processing is digitized and a circuitry is simplified.

Abstract: PURPOSE:To relieve the load onto a CPU by displaying that an original size is not detected when not detected with respect to an inquiry of an original size from a host so as to implement the processing for the purpose in a short time. CONSTITUTION:When a scanner 2 is set to an automatic size detection mode and scanner reading is commanded, a size code is fed to a host 3 in reply with a set size inquiry command from the host 3. When the scanner 2 does not detect the size, a size undetection code decided in advance is fed to the host 3 as a size code. Then it is displayed on a CRT 4 to provide a command of size detection to the user. When the size is detected, reading is commanded to the scanner 2. Since no special error processing different from a regular routine is required, even when the scanner 2 does not detect the size, the processing for the purpose is implemented in a short time and the load onto the CPU is relieved.

Title: Process and apparatus for burning residual gas on change-over of combustion in coke oven
Inventor: KAKIMOTO HIROFUMI
IPC: C10B21/16
Filed: 1989-03-15
Abstract: PURPOSE:To prevent a residual gas in an oven form escaping into the atmosphere at the time of change-over of a gas burning chamber and an exhaust gas chamber and to improve the combustion efficiency by opening an air cap on the gas side of a wast change valve for change-over only for a short period during change-over. CONSTITUTION:When a combustion gas change-over cock 33 is closed in order to change over two chambers 23a and 23b in a combustion chamber 23 for a combustion gas in a cock oven 21 to act as a gas burning chamber and an exhaust gas chamber, respectively, the combustion gas remains between the cock 33 and a heat storing chamber 24a. Then, after an air cap 40 on the gas side of a wast change valve 35 for change-over is opened only for a short period during change-over, the cap is closed. The waste change valve 35 on the rear side which has been on the exhaust gas side until then is closed, and the wast change valve 35 on the front side which will be on the exhaust side is opened. Thus, the above residual combustion gas is introduced from the combustion chamber 23 into the heat storing chamber on the rear side to burn it, and the combustion gas and air are supplied into the heat storing chamber which will now be on the combustion gas side and on the air side to start the combustion.

Title: Color correction of color image signal

IPC: H04N1/46
Filed: 1988-03-15
Abstract: PURPOSE:To certainly match a reproduced color, by converting the color signal of the first system according to the corresponding relation of data for allowing a measured value to correspond in each color space to set the color reproduced by the second system to a required color. CONSTITUTION:In forming a color image from a color signal of digital data, a large number of color patches capable of expressing the respective color reproducing regions of two kinds of different color reproducing systems over the whole are prepared so as to correspond to the data of the respective systems. Each of the color patches is measured by a substantially common measuring device (e.g., colorimeter or densitometer) to form the measured value in a color space at every system. The corresponding relation of data for allowing the measured value to correspond in each color space is calculated and the color signal of the first system is converted on the basis of said corresponding relation to perform color correction and the color reproduced by the second system is set to a required color. By this method, since the difference in color reproduction by the different systems is corrected over the whole of the color space, the color reproduced by the second system can be set to the required color.
