Title: Inverter circuit
Inventor: HARA TAKAHIRO
IPC: H02M7/538
Filed: 1982-01-30
Abstract: PURPOSE:To reduce switching loss and to improve efficiency, by providing base current control circuits, which flow reverse base currents to a pair of transistors that are conducted alternately when they are transferred into an OFF state. CONSTITUTION:Series circuits of chokes CH1 and CH2 and capacitors C3 and C4 are connected to a DC power source E on the side of primary windings NP1 and NP2 of an inverter transformer T. Diodes D3 and D4 prevent the turning ON of the transistors TR1 and TR2 in the reverse direction. Diodes D5 and D6 constitute the base current control circuits Q1 and Q2. When the transistors TR1 and TR2 are turned OFF from ON, the voltages of the primary windings NP1 and NP2 (resonant capacitors C1 and C2) are applied to the bases of the transistors TR1 and TR2. The reverse base currents are flowed to the transistors TR1 and TR2.

Title: Oil separator
Inventor: HAEDA YOSHIO
IPC: F25B43/02
Filed: 1992-01-30
Abstract: PURPOSE:To provide an oil separation mechanism which is excellent in performance by adopting an optimum combination of structure for separation by the action of centrifugal force, strike, element-induced diffusion and expanding. CONSTITUTION:A cylinder-shaped refrigerant gas guide board, a buffer board 8 and an element 9 are combined inside an enclosed vessel, thereby constituting an oil separator. The separated oils 14 and 15 are taken out from the lower part of the enclosed vessel while the oil separated at the element portion is combined with the above oils and taken out by welding the tubes.

IPC: F24F1/00
Filed: 1987-01-23
Abstract: PURPOSE:To provide an outer wall with air conditioning function which secures a large living space without occupying much space in the outdoor and in the room and is of simple structure and low cost and, furthermore, high in the efficiency of room cooling and room. heating by placing a heat pump device for room heating and room cooling in the main body of an outer wall. CONSTITUTION:A condenser 10 is placed in the lower air passage 6 and an evaporator 9 in the upper air passage 3, and because the direction of the flow of the coolant in a heat pump 20 is constant, parts such as four-way valve are not necessary, making the structure simple. During room heating, the room air is sucked from a lower suction port 7 and it is heated by the condenser 10 and then blown out into the room from a lower blowing-out port 8. Because the hot air is blown out into the room 18 at its lower section as described above, the effect of room heating is high. During room cooling, the air in the room is sucked in from the upper suction port 4 and cooled by the evaporator 9 and blown out of the room from an upper suction port 5. With this arrangement the cool air is blown out to the upper section of the room 18, making the room cooling efficiency high.

Inventor: MASAI TADAHISA
IPC: F04D29/44
Filed: 1989-01-24
Abstract: PURPOSE:To reduce the noise of a nose and make the aerodynamic performance improvable by forming the nose in the shape of inclined face to cut air flow obliquely, forming the nose with cushioning material to absorb the impact, and specifying the shape and the mounting means of the nose. CONSTITUTION:Air flow discharged from a fan rotor exit 4 collides with a cushioning material 10 on a nose 13, and the speed of the air flow is large on the upstream side against the rotational direction of fan and small on the downstream side. Therefore, it becomes an intermittent noise generation of the cushioning material 10, and a nose inclined face 12 is provided with an angle relatively made at theta against the exit air flow 7. By making the angle large like this, the exist air flow 7 successively comes into collision with the air flow 7 from the fan rotor exit 4 from the bottom, and the collision of the air flow 7 to the nose 13 can be softened. Further, by making the angle theta larger, the collision can be made possible continuously till the adjacent exit 4, and the collision can be further softened. Also, the top end of the nose 13 is formed with hard rubber cushioning material to absorb shock and prevent the noise generation.

Title: Wire-bonding method
Inventor: NISHIURA SHINICHI
IPC: H01L21/60
Filed: 1997-01-13
Abstract: PROBLEM TO BE SOLVED: To form a stable wire loop shape having a high shape-holding force by deforming slant parts of a trapezoidal loop. SOLUTION: A first reverse action deforms a part 3a of a wire 3 and a capillary 4 lifts to a point D to feed a wire 3 and moves in the opposite direction to a second bonding point G, i.e., a second reverse action moves it horizontally to point E, thereby deforming a part 3b of the wire 3. The capillary 4 is lifted to a point F1 to feed the wire 3, moves to a point G, and is lifted to a point F to feed the wire 3, thereby deforming a part 3c of the wire 3. Then, the wire 3 is bonded to the point G by the normal method. The deformed part 3c for slant parts 34, 35 and hence becomes stable to form a wire loop having a high shape-holding force.
