Title: White balance time lapse compensation circuit
Inventor: OTAKE KEIICHI
IPC: H04N9/73
Filed: 1990-11-30
Abstract: PURPOSE:To suppress the deviation of white balance by providing a luminance detection circuit which measures the luminance of a tube face and converts it to a voltage, and a video signal adjusting circuit which controls the amplitude of a video signal for R, G, and B, respectively corresponding to a luminance detection voltage value outputted from the luminance detection circuit. CONSTITUTION:Since a current flows on a resistor R1 in proportion to light quantity when the luminance detection circuit 100 receives light emitted from the tube face by a phototransistor TR1, a luminance detection voltage PH is decreased according to the decrement of luminance. The luminance detection voltage PH is added by resistors R2, R3 and a variable resistor VR1, which decreases the voltage of the amplitude adjusting terminal RA of the video signal adjusting circuit 200. Therefore, it is possible to always keep the white balance by decreasing the amplitude of the video signal R even when the luminance of the tube face is decreased due to the increment of video display accumulative time. Thereby, a beautiful video keeping the white balance can be always displayed even when the luminance of the tube surface is decreased.

Title: Mold device
Inventor: TAKAHASHI JUNICHI
IPC: B29C45/33
Filed: 1994-12-28
Abstract: PURPOSE: To prevent a mold device from being broken by movement of a slide member by a method wherein a mold device provided with a pair of slide members moving at right angles to a mold opening/closing direction is provided with a means for temporarily fastening the slide members when the slide members are opened and a means for releasing the fastened state at the completion of the closing movement of the mold.

Title: Imaging apparatus
Inventor: ENDO OSAMU
IPC: G03G15/05
Filed: 1998-11-30
Abstract: PROBLEM TO BE SOLVED: To eliminate positional shift of image by shifting the timing for applying a flight bias to each flight control electrode individually from a regular timing based on the theoretical value and actually measured value of a timing for detecting a reference image formed at a specified timing on a counter electrode or a recording member. SOLUTION: A control section 12 forms a single line image 16 of a reference image, at a specified timing, in the vicinity of the end part of a sheet carrying belt 2 and begins to count the elapsed time upon starting sormation of the image 16. When the image 16 formed on the belt 2 passes directly under an image sensor 15 through surface movement of the belt 2, the sensor 15 delivers a detection signal to the control section 12. Subsequently, count operation is ended and the time elapsed after starting formation of the image 16 before receiving the detection signal is determined. Based on the comparison results of the theoretical value and measured value of detection timing, on/off timing of an image signal voltage to each ring electrode of an FPC 102 is corrected and an image signal is transmitted to a high voltage driver IC 10 based on the correction results.
