Title: Image processor
Inventor: KAMIYA YUJI
IPC: H04N1/40
Filed: 1997-12-01
Abstract: PROBLEM TO BE SOLVED: To determine the image qualities in length and breadth directions of input image and to improve compression ratio, while maintaining the image quality. SOLUTION: Original image signals outputted from an image scanner 10 are stored in an image memory 12. A sampling device 14 samples the six parts of the image signals of the image memory 12 and stores them in an image memory 16 for FFT. An FFT transformer 18 fast Fourier transforms image information stored in the image memory 16 for the FFT and normalizes the sum of six frequency components by a DC component. A statistic processor 20 statistically processes the Fourier transformation coefficient of the FFT transformer 18 and determines the image qualities in length and breadth directions of an image.  In the compression encoder of a JPEG system composed of a blocking circuit 22, a DCT circuit 24, a quantization circuit 26, a difference circuit 32 and a variable length encoding circuit 34, the quantization circuit 26 uses a quantization table 28 selected corresponding to the determined result of the circuit 20 and quantizes the output of the DCT circuit 24.

IPC: H04N5/68
Filed: 1988-12-26
Abstract: PURPOSE:To protect a linear cathode by discontinuing the emission after keeping a linear cathode driving pulse at a high potential via a linear cathode driving pulse changing circuit in case a diode is short-circuited. CONSTITUTION:A diode short-circuit detecting circuit 51 detects the short-circuit of a diode 47 based on a current. A linear cathode pulse changing circuit 52 discontinuous the emission after keeping the linear cathode driving pulse at a high potential when the circuit 51 detects the short-circuit of the diode 47. In other words, the circuit 51 detects the short-circuit of the diode 47 based on a current in case an overcurrent flows to the diode 47 by some reason and the diode is short-circuited. Then the circuit 52 keeps the linear cathode driving pulse at a high potential based on the detecting result of the circuit 51. Thus no electron is emitted, therefore no excessive current flows to the linear cathode 2. Thus it is possible to prevent the disconnection of the cathode 2 which is cased by short-circuit of the diode 47.

Title: Multilayer resin pipe for cool water and hot water supply equipments
Inventor: IWASAKI SHINICHI
IPC: C08K5/13
Filed: 1995-12-19
Abstract: PROBLEM TO BE SOLVED: To suppress the amount of an oxidizing deterioration preventive agent in the innermost layer at the minimum, and to improve the chloride water resistance, by specifying the content of the oxidizing deterioration preventive agent in the outer layer, to the content in the innermost layer. SOLUTION: This multilayer resin pipe consists of two or more layers, and the content of an oxidizing deterioration preventive agent of the outer layer is made 1.5 times of the content of the innermost layer. The resin is at least one resin selected from poly-1-butene and silane bridging polyethylene, and the oxidizing deterioration preventive agent is at least one compound selected from a group which consists of hidered phenol system compounds and hindered amine system compounds. The service life of the pipe is determined by the deterioration of the innermost layer, and in order to prevent the deterioration, the maximum of oxidizing deterioration preventive agent is necessary to the innermost layer.  Since the amount of the oxidizing deterioration preventive agent in the innermost layer is reduced gradually in the pipe using condition, the oxidizing deterioration preventive agent mixed at a high density to the outer layer is supplied gradually to the innermost layer, as the reduced amount, for a long period. By such a way, the chloride water resistance can be improved.
