Title: Light-alloy piston for internal-combustion engine
Inventor: TANAKA ATSUO
IPC: F02F7/00
Filed: 1985-03-26
Abstract: PURPOSE:To let a virtual surface twist in a spiral form and improve a heat resisting impact characteristic ever so high, by giving a specified twist to a high tensile strength fiber constituting a thermal strut. CONSTITUTION:A piston is made up of casting a light alloy in high pressure. A thermal strut 32 is cast in a skirt shoulder part 30 by means of internal chill casting. A high tensile strength fiber is rolled on a holder 34 as being given a twist. For this reason, one piece of yarn in a specified volumetric ratio is formed while giving a twist of 10-30 times per meter to several thousands of high tensile strength fibers, and this yarn 36 is rolled on the holder 34 over 10-30 times, forming a holder/fiber built-up body. Thus, the heat resisting impact characteristic of the piston is improved and, what is more, a destructive crack is preventable from occurring.

Title: Gas turbine combustor
Inventor: ITO MASAMICHI
IPC: F23R3/40
Filed: 1986-03-19
Abstract: PURPOSE:To make a uniform distribution of fuel at a downstream side of a catalyst and restrict a generation of NOx by a method wherein the catalyst is mounted in one of passages and a fuel supplying means is mounted in the other passage. CONSTITUTION:Fuel supplied from a fuel nozzle 1 is sufficiently mixed with combustion air 3 under operation of a swirler 8 to make mixture gas. The mixture gas is ignited with a spark plug 2 and its temperature is increased to a certain degree. The mixture gas may be another mixture gas in which fuel is added from a fuel nozzle 1'. An outer flow passage 9 is provided with a fuel supplying nozzle 1'' and its inner flow passage 10 is provided with a catalyst 7. The mixture gas discharged from the flow passage 9 and the combustion gas discharged from the catalyst 7 are mixed at downstream side of the catalyst. Since the mixture gas and combustion gas which are sufficiently mixed to have a high fuel concentration are mixed to each other, a rear part of the flow passage has a uniform distribution of concentration and then a gas of high concentration of fuel is generated. Due to this fact, the fuel shows a complete combustion in this area with hardly generating NOx.

Title: Noise suppression circuit for audio signal
Inventor: WATAYA YOSHIZUMI
IPC: G11B20/02
Filed: 1981-04-22
Abstract: PURPOSE:To suppress noise to an extent without hindrance practically, with a simple constitution, by linearly interpolating a signal level before and afte the production of noise through the utilization that the time interval of noise generated at reproducing track changeover is constant. CONSTITUTION:A pulse having a width corresponding to a prescribed noise period in the time width of track changeover is generated from a monostable multivibrator 14 with a track changeover signal from a terminal 13 to trigger a monostable multivibrator 15 generating the same width, and a Q output of the multivibrator 15 controls the turning on of a switch circuit 11 and a Q' output controls the turning off of switch circuits 3-5. A voltage of a capacitor 8 with the audio input just before the generation of noise due to track changeover from a terminal 1 is subtracted with a voltage of a capacitor 7 in response to the audio input just after the generation of noise via a delay circuit 2 at a subtraction circuit 9 to control the charge/discharge of a capacitor 6 via a variable current source 10. Linear interpolation is made by utilizing that the time width of noise is constant in the signal level just before the generation of noise, allowing to suppress noise to an extent that gives no hindrance practically with a simple constitution.
