Title: Method for automatic channel selection of radio receiver
Inventor: MIYAMA HIROYUKI
IPC: H03J7/18
Filed: 1988-06-13
Abstract: PURPOSE:To preset a prescribed number of stations whose reception electric field strength is strong to a preset memory automatically by attenuating a received electric field strength by an attenuator when an intensity command signal is saturated and setting the intensity instruction signal to a comparable level. CONSTITUTION:A level detector 18 generates an intensity instruction signal E1 in response to an antenna reception electric filed strength E0. If the intensity indication signal E1 is saturated and the comparison with the reception electric field strength E0 is disabled, the reception electric field strength E0 is attenuated by the attenuator 1 to bring the level of the intensity instruction signal E1 into a comparable level, and the electric field strength of a reception station is compared based on the attenuation at that time and the level of the intensity instruction signal E1. Thus, even with a strong reception electric field strength E0, the electric field is identified and stations with the strong reception electric field strength E0 are preset into a preset memory 20 by a prescribed number automatically.

Filed: 1983-08-12
Abstract: PURPOSE:To simplify a control mechanism of a photodetecting element and to attain the miniaturization of an optical head by dividing a reflected luminous flux into two parts through a prism having different output angles and leading these divided luminous fluxes to the 1st and 2nd 2-split phtodetecting elements which are unified on the same plane. CONSTITUTION:The light 10 delivered from a semiconductor laser 1 and reflected by a disk 8 is reflected again by a polarizing/reflecting surface 5a of a polarized beam splitter 5 and made incident on a prism 31. The lower half of the luminous flux goes straight to be turned to a focused beam 33a and made incident to 2-split areas 34a and 34b of a photodetecting element 34. While the upper half of the luminous flux is polarized into two directions to be converted into focused beams 33b and 33c and made incident on 2-split areas 34d and 34e of the element 34. A focus error signal is obtained from the difference between output signal of areas 34a and 34b. While a tracking error signal is obtained from the difference between output signals of areas 34d and 34e. In such a way, the control mechanism of the element 34 is greatly simplified.

Title: Liquid fuel combustion equipment
Inventor: HASHIDO KENKICHI
IPC: F23D11/40
Filed: 1986-06-23
Abstract: PURPOSE:To provide clean and safe liquid fuel combustion equipment, by extending the internal diameter of an injection part at the end of a fuel feed pipe so as to form a bell shape. CONSTITUTION:A combustion is started when a mixed gas of fuel and air is ignited and a flame 16 is formed on a burner port 14. At that time a flow of fuel from a fuel feed pipe 20 makes a complete injection into an atomizing cup 11 every time, synchronized with the pulsation of a fuel pump 21. No liquid droplets will remain at the end part. Because the internal diameter of an injection part 20a at the end of a fuel feed pipe 20 is extended so as to form a bell shape, the remainder fuel after one pulsating injection will stay in the expanded part by the surface tension of it. Thereby, the remainder fuel will never stay as droplets on the back surface of an end part, so that the concentration of a mixed gas is quite stabilized, and a momentarily incomplete combustion can be prevented.
