Title: Power supply for traveling wave tube
IPC: H01J23/34
Filed: 1992-03-31
Abstract: PURPOSE:To prevent 'a hiccup phenomenon' in a TWT power source at the time of the start-up of a high-pressure generating part, by obtaining A.C. voltage detection voltage from the output of a transformer in a control circuit for rising a high-pressure generating part. CONSTITUTION:In a transformer 1, A.C. voltage is lowered, and output is fed to a control power source 2 rising a high-pressure generation part. A part of the output of the transformer 1 is smoothed with a diode 3 and a capacitor 4 to be applied to an A.C. voltage detection circuit 5. By the output of the transformer 1 before the high-pressure generation part is rised, current is fed to the control power source 2 and the detection circuit 5, and after rising, the current is fed via a diode 6 from a power source generated by the high-pressure generation part itself. Setting operating voltage, in the A.C. voltage detection circuit before the rising, to the lower limit of a standard, causes applied voltage to the detection circuit 5 after the rising to be increased than before the rising, consequently preventing 'a hiccup phenomenon'. Setting operating voltage, in the detection circuit 5 after the rising, to the lower limit of the standard, causes an A.C. power source voltage at the time of the rising, to be increased than the lower limit of the standard, preventing input current increase following A.C. power source voltage lowering.

Title: Power supply for driving x-ray tube
Inventor: TOMIZAWA MASAMI
IPC: H05G1/12
Filed: 1991-04-08
Abstract: PURPOSE:To reduce the adverse effect accompanying the ripple of tube voltage by intermitting the switching operation synchronously with AC input, and synchronizing the ripple of X-ray driving voltage with the AC input. CONSTITUTION:As regards the relation between the input waveform from an AC power source 101 and the switching operation of a switching part 103, the zero cross point of the input waveform can be detected since an oscillation controller 1 is provided in the switching part 103. Accordingly, the switching operation is started from the zero cross point of the AC input, and the switching operation is performed only for a certain time shorter than half the synchronization of the AC input, and the switching operation is stopped until the next zero cross point. By repetition of this, switching becomes possible such as that the phase of the switching part 103 becomes fixed certainly at the zero cross point of the AC power source 101. This way, the adverse effect accompanying the ripple of tube voltage can be reduced.

Title: Picture processing unit
Inventor: IMANISHI MASAHIRO
IPC: H04N1/40
Filed: 1993-03-09
Abstract: PURPOSE:To eliminate the need for picture adjustment and to improve the job efficiency by providing a means correcting automatically a designated part for prescribed processing to the processing unit when there is a different part in a picture subject to prescribed processing from an original picture and the original is read again while the part is designated. CONSTITUTION:An original printed unevenly in a single red color is subject to white/ black level pattern processing and the result is outputted from a picture output device 7. A hue discrimination LUT 4 discriminates the picture to be a red pattern and a partially yellow pattern. In this case, the operator sets the mode to a picture adjustment mode to designate the yellow pattern portion and allows a reader 1 to read the picture again, and a hue discrimination circuit 5 discriminates whether or not the designated part is in a hue danger area. When the part is resident in the area, the LTU 4 moves automatically a border line of the hue danger area to correct the designated part to display a red pattern. Moreover, when a chromatic/achromatic color discrimination circuit 3 discriminates that a frequency distribution curve of a difference between a maximum and a minimum RGB luminance level crosses a threshold level, the circuit 3 expands the range of the chromatic color. Thus, no picture adjustment is required and the job efficiency is improved.

Title: Liquid crystal device and electronic equipment
Inventor: SAKATA HIDEFUMI
IPC: C08J5/18
Filed: 1999-03-19
Abstract: PROBLEM TO BE SOLVED: To obtain a liquid crystal device that can compensate retardation individually for each color and can optimize modulation of each color by changing the thickness of the liquid crystal layer at the position corresponding to the respective color of the color filter, by constituting the substrate of a phase difference film and controlling the thickness of the substrate to be different for every color element of the color filter. SOLUTION: A liquid crystal layer L is held between a pair of phase difference film substrates 10, 20. The phase difference film substrates 10, 20 are prepared by uniaxially or biaxially stretching a base film having 100 to 300 μm thickness to impart double refraction. Thereby, the thickness of the phase difference film is controlled for every color element to obtain desired double refraction. By controlling the thickness of the phase difference film to obtain the optimum double refraction for each color element, the double refraction can be compensated for every color and coloring by the liquid crystal layer can be eliminated. Thus, coloring in the display or decrease in the contract can be effectively prevented.
