Therefore, the inspection is performed without being affected by the performance of a PC with constant stability and reliability.

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: Several embodiments of rotating electrical machines where cogging torque is reduced as well as the distortion of the back emf and improve torque characteristic with reduced torque ripples by dividing either the permanent magnets and/or the poles of the coil windings in axially separated portions that are circumferentially shifted relative to each other.

Abstract: A simplified electrical generator for an internal combustion engine in which the hub portion, magnet carrying portion and race for a one way clutch are all integrally formed to provide a more compact, lighter and lower cost assembly.

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: An electrical device having a number of embodiments of multi phase armatures incorporating terminal circuits with maximum efficiency and the ability to use automated techniques as well offering greater flexibility in the way the coils are arranged in the desired types of circuits.

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.

Abstract: Two embodiments of rotating electrical machines wherein the cogging torque is substantially reduced by increasing the cogging number without increasing the number of pole teeth and permanent magnets. This is done by selecting the appropriate magnet angle to increase the number of coggings per revolution and this can be done using a computer analysis of the cogging torque for the individual magnets rather than by a trial and error method.
