Filed: 1998-05-27
Abstract: PROBLEM TO BE SOLVED: To quickly, efficiently and quietly ventilate air without expanding in a cabin by imparting an air ventilating, circulating and air blowing function in the cabin. SOLUTION: Air and smoke are sucked in from a ceiling part intake port 1 by force of an air blower 4, and when air is wished to be ventilated, a valve 5 is put in a ventilatable position to release air outside from a rear exhaust port 2, and when air is wished to be blowen and circulated, a position of the valve 5 is changed so that air can be exhausted from a lower exhaust port 3 by pssing through a filter 6. In such constitution, when the valve 5 is operated by turning on a switch of the air blower 4, air in a cabin can be ventilated, circulated and blown. Efficiency is increased further by taking in and simultaneously using outside air from an air conditioner. Since air is sucked in from the ceiling part intake port 1 and is exhausted from the lower exhaust port 3, air can be circulated and blown.

Title: Amorphous or crystalline low polarizing thin-film
Inventor: KOBAYASHI KEIJI
IPC: H01L21/314
Filed: 1982-10-25
Abstract: PURPOSE:To obtain an amorphous semiconductor low polarizing thin-film, the polarizability of ions therein extends over a comparatively small range of 0.007-1.00, by reducing the surface charges of a semiconductor surface by using low polarizing glass. CONSTITUTION:When a large amount of Pb<4+> and Tl<3+> are made contain in glass, large surface charges E2=Qd/K0E0 are generated in the semiconductor surface because the mol polarizability of these ions increases. Consequently, surface charges E2 are halved approximately when mol polarizability is reduced to half conventional thin-films, and the surface charges E2 of the surface of Si reduce by using low-polarizing glass. When the glass of 0.75 B2O3, 0.20 SiO2 and 0.05 MgO is manufactured, the mol polarizability Pm of the material is represented by formula Pm=0.0076X(mol% of B2O3)+0.084X(mol% of SiO2)+0.238X (mol% of MgO) (where the mol polarizability of B<3+>, Si<4+> and Mg<2+> is each 0.076, 0.084 and 0.238), and Pm=0.0309 is formed. The glass is excellent in viscous flow, and can be changed into a thin-film.

Abstract: PURPOSE:To prevent generation of a contact spark in a switching means and flowing of a rush current by switching an inverter equipment and a commercial power from one to another at a zero-crossing point at the time of switching between said inverter equipment and commercial power. CONSTITUTION:A commercial zero-crossing detection means 10 and an inverter zero phase output means 15 are provided in an apparatus.

Title: Temperature controller
Inventor: UEDA YASUKIYO
IPC: G05D23/24
Filed: 1980-12-26
Abstract: PURPOSE:To exercise high-precision temperature control by detecting a current, flowing through a sensor, by a transistor (TR) and connecting a diode in parallel to the TR. CONSTITUTION:When the side (a) of an AC power source VAC has a negative potential, a current IT flowing through a sensor 3 is the collector current IC of a TR32 and integrated by a circuit of a capacitor 33 and a resistance 34 to be converted into a temperature signal potential VT. The current IT varies with the detected temperature of the sensor 3, so temperature control has high precision. If the power of the power source VAC rises, a potential VCC rises and the current of a current mirror circuit 30 also increases, so a set potential VS decreases to compensate decrease in potential VT. When the side (a) is positive, on the other hand, the current of the sensor 3 flows through the diode 35, so an exactly symmetic AC voltage is applied to the sensor 3, so that the deterioration of the sensor 3 due to polarization is prevented.
