Title: Filter medium for cleaning air
Inventor: TOKUDA SEIJI
IPC: B01D39/14
Filed: 1999-04-14
Abstract: PROBLEM TO BE SOLVED: To easily produce a filter medium which is low in pressure loss and high in the capability of removing particle materials by employing synthetic polyolefin-based fiber having deodorizing function as at least one fiber of various mixed fibers used as the filter medium for cleaning air. SOLUTION: In the filter medium for cleaning air, made of fibers mixed with at least two kinds of the fibers, at least one kind of the fibers is a synthetic polyolefin-based fiber as well as having deodorizing function. At that time an electret fiber is preferred for the synthetic polyolefin-based fiber and each of these fibers is preferably fused by a fusible fiber. For example, in the case of removing smoke particles, a box 1, a digital dust meter 2, a filter holder 4 and a diaphragm pump 5 are connected in this order as a performance- evaluating device for the filter medium, and the smoke of tobacco 7 burned in the box 1 is filtered by the sample 3 of the filter medium.

Title: Translator for converting differential input into single ended output
Inventor: FREITAS OSCAR W
IPC: H03K19/0185
Filed: 1999-04-14
Abstract: PROBLEM TO BE SOLVED: To provide a wide range load without a change in a basic design by supplying current to an output node, permitting a complementary logic high signal to completely turn on a second pull-up facilitation transistor, applying a logic low signal to the control node of a second pull-up transistor and completely turning on the second pull-up transistor. SOLUTION: When GTLPINPUT is switched to be low, Vout becomes high through two routes which simultaneously, operate in parallel to certain time. The first route for supplying current required for switching Vout to be high becomes off before Vout becomes Vcc and pull-up to Vcc is entrusted to the other route for completing it. When it is once realized, Vout is maintained to a state where it is directly connected to Vcc through a transistor QP8. The QP8 is maintained to be on until a circuit is switched next and Vout is connected to Vcc.

Abstract: PURPOSE:To provide a static pressure bearing which can keep a bearing gap constant even in the case of a sudden change in fluid temperature by providing fluid paths on the inner and outer surfaces of a bearing sleeve and a bearing bush, both thermal capacities thereof being equal. CONSTITUTION:A static pressure bearing includes a bearing sleeve 15 fitted close to a shaft 16 piercing an upper low-pressure chamber 8 formed by a bearing casing 5 and an outer casing 11.

Title: Resonant-type switching power supply unit
Inventor: IMAMURA NORITOSHI
IPC: H02M3/28
Filed: 1998-04-17
Abstract: PROBLEM TO BE SOLVED: To improve the efficiency of a current resonant-type switching power supply unit by reducing switching loss, when resonance current is switched. SOLUTION: In this switching power supply unit, when MOS transistors Q1, Q2 are alternately turned on, switching current flows through the primary winding L1 of a transformer, and an AC power is transferred to the secondary side. Alternating voltage generated at a secondary winding L2 is able to turn the primary side into a resonant state by connecting resonance elements C3 (C4), L3 (L4) to the winding L2 which is the output winding of an isolation transformer T which is full-wave-rectified by diodes D1, D2, thus providing current resonant-type switching power supply unit, Since the leakage inductance of the transformer is not made a resonance element, the section between the windings of the isolation transformer can be coupled closely, and since the resonance current is not interrupted directly, the peak value of the primary current drops, thus enabling reduction in switching loss.
