Air forced into the shelf board combined outlet duct 5 through the air duct 10 is exhausted through an outlet opening 5d of the shelf board combined outlet duct 5, and air curtain is formed along the opening of the storage section 11 of a cabinet 1. Therefore, air in the storage section 11 of the cabinet 1 is circulated and purified, while getting caught in a circulating airflow including the air curtain.

Abstract: A number of embodiments of rotating electrical machines and methods for winding them that provides a high space utilization and very effective winding with less likelihood of damage to the insulation of the wire of the winding during the winding process. The arrangement basically does not require the winding needle to be moved back and forth in the slot between the poles but rather employs insulating inserts that are positioned on the axial faces of the poles outside of the gaps for guiding the wire from one end to the other so as to provide the high space utilization. In one embodiment the insulating insert effectively changes the circumferential length of the coil winding that decreases in an axial direction along their length.

Abstract: A number of embodiments of rotating electrical machines using permanent magnets wherein the cogging torque is substantially reduced as are vibrations caused by magnetic flux variations. This is accomplished by disposing the coil windings in equal circumferential spacing and disposing the associated permanent magnets in non-symmetrical relationship so that the gaps between some of the magnets are different. In addition, the coil windings are such that no two coils of any phase are immediately adjacent each other in a circumferential direction. A method for calculating the optimum spacing is also disclosed.

Abstract: An engine speed control that avoid undesirable transmission conditions such as clutch chattering. This is done by sensing actual conditions, which are likely to result in the undesirable transmission conditions such as clutch chattering and only changing the engine output when these exact conditions are found. The conditions sensed are the determination of excessive acceleration in engine speed or in the speed of a shaft associated with the engine or the degree of rotational variation or rotational acceleration.

Abstract: An improved high pressure intermeshing gear pump that achieves high efficiency and a low cost by forming the pumping cavity such that no fillets exist at the corners permitting closed fits without utilizing bearing end plates. In addition an improved coupling between the gears and their supporting shafts is disclosed as is a simplified machining method that eliminates burrs that may be formed during the drilling operations.

Abstract: Two embodiments of very simple by highly effective antitheft devices for use in small vehicles such as motor scooters, personal watercraft or other forms of watercraft. Each system employs a removable component which also functions as a display and which disables the operation of the prime mover of the vehicle. The removed component can be carried by the user and reinserted when he desires to again operate the vehicle.

Abstract: A semiconductor chip mounted on a substrate having a soldering land pattern for containing a molten solder interposed between said conductive surface and a facing surface of the semiconductor chip. The soldering land pattern comprises corners spaced respectively from the four corners of the semiconductor chip bottom surface and escapes formed between the corners sufficiently outside of the respective sides of the semiconductor chip bottom surface to accept liquid solder displaced from the area between the conductive surface and the facing surface of the semiconductor chip upon placing the semiconductor chip within the soldering land pattern to improve conductivity and simplify the construction. The device is also shown in a motor control.
