Title: Two-cycle internal combustion engine
Inventor: ASAI MASAHIRO
IPC: F02B21/00
Filed: 1997-05-24
Abstract: PROBLEM TO BE SOLVED: To prevent a drop in engine output and the seizure of a piston by making the height of the fuel or fuel-air mixture injection port of a combustion chamber smaller than a distance between the outermost sides in the axial direction of cylinder of a plurality of piston rings. SOLUTION: A thick fuel-air mixture injection control valve 24 is fitted in the valve receiving hole 23 of a communicating passage 21 for making a chamber 20 communicating with a combustion chamber 13. The injection port of a fuel injection unit 26 is disposed in the upstream 21b of the communicating passage 21 and highly compressed gas can be supplied into the chamber 20 from a highly compressed gas intake port 27. When the injection control valve 24 is opened, this highly compressed gas is mixed with the fuel supplied from the fuel injection unit 26 in a mixing chamber 21c to make thick fuel-air mixture and is injected from a thick fuel-air mixture injection port 22.  The height Ha of the thick fuel-air mixture injection port 22 and the height Hc of the highly compressed gas intake port 27 are made smaller than a distance Hb between the outermost sides A, B in the axial direction of cylinder of piston rings 29a, 29b. This eliminates the leak of fuel-air mixture and combustion gas into a crank case.

Title: Video signal recording and reproducing device
Inventor: NAKAI TAKAHIRO
IPC: G11B20/06
Filed: 1988-06-17
Abstract: PURPOSE:To improve S/N while preventing inverse phenomenon by arranging a limiter and a low-pass filter(LPF) behind a regenerative RF equalizer. CONSTITUTION:The FM wave outputted from a regenerative equalizer 4 is inputted to a limiter 5, and the square FM wave outputted from the limiter 5 which converts the FM wave to a square wave is inputted to a TAN type digital FM demodulator 16 after being converted to a sine wave and is subjected to FM demodulation. Consequently, the FM wave outputted from the regenerative equalizer 4 is converted to the square FM wave by the limiter 5 and is inputted to the LPF 6 to eliminate most of tertiary or higher harmonics more than three-dimension from the spectrum of the square FM wave. Further, a fundamental wave component covering a practically sufficient range is extracted to output the sine FM wave. Thus, the limiter and the TAN type digital FM demodulator are used to improve S/N while preventing an inverse phenomenon.
