Title: Illuminant for photocatalyst
Inventor: KIMURA HIDEYUKI
IPC: A61L2/16
Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To maintain a photocatalistic function even if a part of a illuminant is failed and improve a reliability by combining plural light-emitting diodes as the illuminant with a photocatalyst carrier and juxtaposing them. SOLUTION: Plural light-emitting diodes 1 is mounted on a substrate 2 by a lead frame so that light illuminates a photocatalyst 4 of a photocatalyst carrier member 3. The light-emitting diodes which are mounted are small size, and a LED grid unit 6 is composed by arranging the small light-emitting diodes 1 like a grid regularly. Both zigzag and irregular arrangements are acceptable. The photocatalyst carrier member 3 is born with the photocatalyst 4 by being glued with an adhesive or a binder and so forth or by being incorporated the adhesive or binder directly. Thereby, the photocatalyst 4 can be irradiated by light of at least two illuminants 1, therefor, if one of the illuminants is failed, the photocatalyst 4 is irradiated continuously and an antibacterial function and a deodorizing function can be maintained.

Title: Solenoid operated valve
Inventor: ISHIKAWA TSUNEKATSU
IPC: F16K31/10
Filed: 1980-08-29
Abstract: PURPOSE: To control two or more valves with different opening characteristics using an electric driver part and also to obtain good accuracy by transmitting the motion of a plunger through a lever.  
     CONSTITUTION: A plunger 1 is pressed upward by springs 28, 29 installed at the lower part of valve body 21, 22, and shifts downward with increase of the current to energize the operating coil 3 to revolve levers 6, 7 around the fulcra 8, 9. Because the distance between the point 16 and flucrum 8 is larger than the distance between the point 17 and fulcrum 9, the point 31 moves downward beyond the point 30 for the same amount of downward movement of the plunger 1. Accordingly, a needle part 24 moves downward more than another needle part 23, so that the increasing rate of the opening area of valve seat 34 is larger than that of another valve seat 33.

Title: Power supply circuit
Inventor: HORIUCHI FUMIO
IPC: H02M3/28
Filed: 1994-05-31
Abstract: PURPOSE:To suppress power loss at the time of power up or abnormal operation of a switching element by forcibly turning a first switching transistor OFF during normal operation thereby interrupting the operation of a starting circuit. CONSTITUTION:Upon power up, the voltage of the power supply circuit increases to a level for turning the base potential of the third switching transistor Q13 in a cut-off circuit 17 ON with a time constant determined by a resistor R11 and a capacitor C11 connected in series. Subsequently, the third switching transistor Q13 is turned ON to pull the base potential of a first switching transistor Q11, reaching the Zener voltage ZD of a Zener diode ZD1, down to the ground potential GND. Since the third switching transistor Q13 is sustained in ON state during normal operation, the base potential of the first switching transistor Q11 is pulled constantly down to the ground potential GND and the transistor Q1 can not be turned ON even upon occurrence of abnormal operation. Consequently, extra power loss is suppressed as low as possible.

Title: Aluminum alloy high damping material and its manufacture
Inventor: HAYASHI MINORU
IPC: C22F1/04
Filed: 1990-05-09
Abstract: PURPOSE:To obtain a material light in weight, excellent in cold workability and furthermore excellent in vibration damping capacity by forming this material of Al incorporated with a specified amt. of Zr. CONSTITUTION:This high damping material contains, by weight, 0.5 to 20% Zr and the balance Al with inevitable impurities. At the time of adding Zr to Al, Al-Zr intermetallic compounds are uniformly distributed into a mother phase.

By this effect, the applied vibration is extremely swiftly damped. For giving this effect, the addition of Zr only is sufficient, but, when Si, Fe, Mn or the like are furthermore added, its vibration damping capacity can moreover be improved.
