Patent JP-S5684075-A (JP)
Title: Automatic gain controller
Inventor: IKEGAMI ICHIROU
IPC: H03G3/20
Filed: 1979-12-12
Abstract: PURPOSE:To enable automatic stable gain control of high performance free from malfunction to an erroneous signal, by generating a reference pulse of constant width by using the leading edge of a synchronizing signal separate output. CONSTITUTION:When a synchronizing signal contracts and a separating circuit operates at the front-poach leading edge of a composite video signal and back-poach trailing edge to output pulse (b'), monostable multivibrator 16 is triggered by the leading-edge rise of pulse (b') appearing at synchronizing-signal separating circuit 15 to generate pulse (C'), so that reference pulse generating circuit 19 will output referefence pulse (C') of time-T pulse width, constant amplitude and a constant base-line level synchronizing with the leading edge of the front poach. The input composite video signal is passed through variable gain circuit 11 and clamping circuit 13 generates signal (d') having the top of the synchronizing signal clamped at voltage VCL. Then, signal (d') and pulse (c') are added together to obtain output (e') and peak holding circuit 17 detects peak voltage VC3. When circuit 11 is balanced by voltage VC1 of circuit 17, voltage VC3 is lower than VC1 and the gain increases to balance the automatic gain controller, so that the output will be constant.

Title: Quantitative fuel pump
Inventor: NAGASAKA KOUJI
IPC: F04D13/16
Filed: 1978-12-26
Abstract: PURPOSE: To supply fuel quantitatively at all times by providing an axial flow pump in a fuel tank in which a fixed liquid level is formed by a constant liquid level former.  
     CONSTITUTION: When the liquid level of the fuel tank 8 is lowered by the driving of the axial flow pump 3, the float 9 is moved downwards and the float arm 10 is turned clockwise, whereby the float valve 7 is separated from the valve sheet 6 to open the fuel suction path 5 and then fuel corresponding to discharged amount to outside by the axial flow pump 3 is supplemented. Thus, even when the axial flow pump 3 is driven, the liquid level of the fuel tank 8 is always kept constant. Since the axial flow pump 3 is provided inside the constant liquid level former 2 and the lift H of the axial flow pump 3 is kept constant at all times, a fixed amount of fuel can be always supplied quantitatively by keeping the turbine revolving number of the pump 3 constant simply.

Filed: 1996-06-21
Abstract: PROBLEM TO BE SOLVED: To execute the reservation of a program by a viewer without mistake by comparing reservation information with program table information corresponding thereto and updating reserved program information when the contents are updated. SOLUTION: A reservation information management section 15 stores reservation information of a program reservation and a group reservation to a reservation information DB 14 for the management and accepts an additional request of reservation information from a program table display/operation section 13 and accepts a delete request of the reservation information from a reservation execution section 17 or a reservation table display/operation section 16. The reservation execution section 17 reads program information a little before a broadcast start time with respect to a program whose broadcast start time is closest based on the contents of the reservation information DB 14 and compares it with contents of a program information DB 10 to confirm whether or not a broadcast start time is changed.  When changed, the contents of the reservation information DB 14 are updated and then the program reserved by the viewer is displayed without mistake.
