Title: Video disk player
Inventor: INAMOTO YOSHIO
IPC: H04N5/93
Filed: 1982-02-15
Abstract: PURPOSE:To eliminate a memory when a static picture is reproduced from a video disk that is recorded by CLV, by giving a jump to a pickup after detecting the 1st position from a reproduced signal, delivering the output of demodulation and stopping the output after the 2nd position is detected. CONSTITUTION:A video disk recorded by CLV is turned by a motor 2, and the recorded signal is reproduced through a pickup 3 and then demodulated to be delivered through an output terminal 4. When a static picture command is delivered from a static picture command means 8, the 1st position detecting means 7 detects the 1st position. Thus a tracking controller 5 generates an output, and the pickup 3 has a jump over a track in the reproduction starting direction. At the same time, an output is generated at a squelch means 9 to avoid output of a demodulated video signal to the terminal 4. Then the demodulated signal is delivered from a track when the pickup 3 has a jump. Thus the 2nd position is detected from the demodulated signal, and the squelch is released for the 2nd position detector 10. As a result, the video signal of one frame is delivered intermittently to the terminal 4.

Title: Transmission system of facsimile equipment
Inventor: HOKURA TOORU
IPC: H04N1/32
Filed: 1981-02-20
Abstract: PURPOSE:To reproduce an image of good quality on the reception side by coinciding carrier waves in phase without reference to the presence of a skip information, etc. CONSTITUTION:A carrier frequency is 2,100Hz when skip information is not present, and 2,550Hz when present. When the skip information is present, 224 is set in a programmable counter 1, which outputs 17 pulse signals. The period of the transmission of those 17 pulse signals correspond to 14 pulse signals outputted when 270 is set in the programmable counter 1. As a result, during a phase signal period TP, a carrier wave without the skip information is in phase or 180 deg. out of phase with that when the skip information is present, and the phase of a drum and that of the carrier wave have a constant relation. Therefor, the stability of transmission is improved to obtain a reproduced image of good quality.

IPC: C12N11/08
Filed: 1996-01-17
Abstract: PROBLEM TO BE SOLVED: To prepare a material comprising an immobilized enzyme, having high enzyme activities and capable of carrying out a reaction at a high speed with a high reactional efficiency. SOLUTION: This porous membrane comprising an immobilized enzyme is obtained by immobilizing the enzyme in a grafted polymer chain introduced into a membranous pore surface of a porous substrate membrane, substantially having a three-dimensional network structure and comprising a polyolefin, a copolymer of an olefin and a halogenated olefin or polyvinylidene fluoride by adsorption or covalent bonds. The porous membrane has 0.01-5μm average pore diameter and 20-90% porosity. This method for carrying out a chemical reaction comprises using the porous membrane and the enzyme as a catalyst.  Since enzyme activities are hardly deteriorated by the immobilization of the enzyme; a substance solution can be made to flow at a high flow velocity even under a low pressure and the enzyme can sufficiently be brought into contact with the substrate to manifest high activities even at a high flow velocity, an efficient enzymatically catalyzed reaction can be carried out.
