Abstract: A vehicle and associated light source that comprises a single source of light and a surrounding housing and lens arrangement that gives the visual effect of multiple light sources.

Abstract: An induction system for a multi valve engine that facilitates operation in a lean burn mode over a large range of speeds and loads by employing a smaller cross sectional branch passages in several induction passages serving a common combustion chamber and a valve arrangement that progressively opens flow first through the branch passages and finally through both the main and branch passages so that maximum power can also be obtained.

Abstract: A cabinet wherein air sucked from an inlet opening 4d of a shelf board combined inlet duct 4 by drive of an air purification unit 3 is passed through the shelf board combined inlet duct 4 and introduced into the inside of a case 3a, and by a dust collection filter 32 and an odor eliminating means 33. 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: To form a dividing portion 21 of an outer ring 13 so that a dividing line is of a crankshaft shape as seen in the axial direction while first and second race ring halves 16, 17 fit to each other. The dividing portion 21 is formed so that first dividing surfaces located on the side of the inside cylindrical surface 14 are in contact with each other in the state of being attached to a cylinder body and a crankcase. The dividing portion 21 is also formed so that a clearance S is produced between third dividing surfaces on radially outer side.

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.

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 machine having a plurality of pole pieces surrounded by bobbins and upon which individual coil windings are formed. The bobbins are formed by a insulating material in which are embedded electrical connectors that have terminal ends that afford connection to the coil windings and to an external connection for either deriving electrical power in the case the machine operates as a generator or receiving power in the event the device operates as a motor. Thus, cost is reduced and at the same time the device is more compact and more efficiency.

Abstract: A pivoting arrangement for connecting an actuator to the outboard drive portion of a marine propulsion unit and more particularly to an arrangement for strengthening the pivotal connection without significantly increasing its size and by simplifying its construction to reduce cost.

Abstract: A tilt and trim system for the outboard drive of a marine propulsion unit wherein the popping up action is effectively damped without positive stops that could cause abrupt stopping and possible damage.

Abstract: A motor control for an electric motor powered vehicle having an accelerator control connected to a control circuit for supplying the desired driving power that senses possible errors of various types and stops the supply of driving power until normal operation resumes.

Abstract: An improved hydraulic system for a marine propulsion unit where it is insured that leakage of the shuttle valve will not permit the propulsion unit to move from the desired position by having a series of shuttle piston operated check valves inn series flow between the pump and the hydraulic unit that controls the position.

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: A spring seat is formed of an outer spring seat 10k and an inner spring seat 10j formed in a stepped-down shape so as to be positioned lower than the outer spring seat 10k, and a valve spring is formed of an outer spring 37 and an inner spring 36 that is disposed coaxially inside the outer spring 37 and that is larger in spring length than the outer spring 37.

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.
