Title: Internal-combustion engine with supercharging mechanism
Inventor: KUSHIDA KAZUMITSU
IPC: F02B29/06
Filed: 1985-07-12
Abstract: PURPOSE:To cool and supercharge a rotary valve by installing a pressurized air supply path in the center of an opening/closing timing controlling rotary valve installed above the exhaust port of a two-cycle engine so as to supply pressurized air in a cylinder when the valve closes. CONSTITUTION:A partition wall 7 divides the upper part of the exhaust port 6 of a two-cycle engine 1 into two stages, and a rotary valve 8 is set at the port part of the upper stage. Pressurized air is supplied from a crank chamber through a port 17 installed at the center of the rotary valve 8, and blown out through a port 18. When a piston 4 goes down, the rotary valve 8 opens to quicken the valve opening timing of the exhaust port 6, and when the piston 4 goes up, the rotary valve 8 closes as shown in the figure to close the exhaust port sooner, avoiding a blowby, as well as creating supercharging effect as the port 18 opens inside a cylinder 3 so that pressurized air for cooling the rotary valve blows out inside the cylinder.

Title: Solid-state image pickup element
Inventor: NAKANISHI TOSHIRO
IPC: H04N9/07
Filed: 1988-06-22
Abstract: PURPOSE:To reduce the size of a camera while holding desirable sensitivity, by using a variable wavelength interference filter for selecting a wavelength band of transmitted light in accordance with the three primary colors so that signals of the three primary colors are taken out of a single pigment in time series. CONSTITUTION:Incident light 2 corresponding to an optical image reaches a solid-state image pickup element after passing through a variable wavelength interference filter 102. The variable wavelength interference filter 102 controls a wavelength band of transmitted light in accordance with respective wavelengths of the three primary colors by a control drive means 117. As a result, the solid-state image pickup element outputs photoelectric conversion signals of red, green and blue signals sequentially at every change of the band in the form of serial signals. Thus, signals of the three primary colors can be outputted from a single photodetector 106 and, therefore, a high-quality image signal can be outputted with high sensitivity. Further, the size of the camera can be decreased.
