Abstract: A video camera recorder (1000) comprises an imaging means (205, 200) for receiving an optical image and generating an image representative video signal (Iv) and a viewfinder (5000) for viewing the optical image. A synchronizing signal generating means (3000) is coupled to the imaging means (205, 200). A recording means (500) is coupled to the synchronizing signal generating means (3000) and to the imaging means (205, 200). A control means (4000) for optimizing power conservation has a first mode of operation in which the control means (4000) enables operation of the synchronizing signal generating means (3000) and inhibits operation of the imaging means (205, 2,00) and the recording means (500). In a second mode of operation, the control means (4000) enables operation of th e synchronizing signal generating means (3000) and the recording means(500) for reproducing a recorded image representative video signal (Pbv) and inhibits operation of the imaging means. In a third mode of operation, the control means (4000) enables operation of the imaging means (205, 200), the synchronizing signal generating means (3000) and the recording means (500) for recording the imag e representative video signal (Iv) from the imaging means (205, 200). The power dissipation of various other systems, for example, an electronic viewfinder (50) or servo system, is controlled responsive to the selected operating mode, video signal presence or absence, and the detection of external coupling.

Abstract: A piston for use in a compressor that compresses gas containing lubricating oil is disclosed.  The compressor includes a housing having a crank chamber and cylinder bores, and a swash plate located in the crank chamber.  The swash plate is operably connected to the pistons by shoes to convert the rotation of a drive shaft to the reciprocation of each piston.  Each piston has a head for compressing the gas supplied to the cylinder bore and a skirt projecting from the head toward the crank chamber.  The skirt is connected to the swash plate.  A restrictor is provided on the skirt to prevent the piston from rotating in the cylinder bore.  The restrictor has a pair of arched surfaces slidably contacting an inner surface of the housing and a recessed surface located between the arched surfaces and free from contact with the inner surface.  The recessed surface defines a gap for allowing passage of the oil between the recessed surface and the inner surface.  The gap leads the oil in the crank chamber toward the shoes when the piston moves from a top dead center position to a bottom dead center position.

Abstract: A bladed rotor and surround assembly comprising an annular casing (18), a bladed rotor element (8b) that is rotatable about an axis (3) concentrically within the casing (18), and an annular shroud liner. The shroud liner, typically made up of an annular array of circumferentially abutting shroud liner segments (32), is disposed within the casing (18) in an annular radial space (31) defined between the casing (18) and an outer circumference of the bladed rotor (8b) . The shroud liner segments (32) have location means (40,46) to locate each segment (32) within the casing (18) . The location means (40,46) and the annular radial space (31) are configured to enable axial insertion of the shroud liner segment (32) between the bladed rotor (8b) and the casing (18). In addition the location means (40,46) and the annular radial space (31) allow a limited amount of radial translation of the shroud segment (32) during insertion. The location means (40,46) also provide a positive radial location to prevent radial translation of the shroud segment (32) once each shroud segment (32) is in a final assembled position.

Abstract: A valve operating system includes a connection switch- over device provided in a plurality of cam followers. The connection switch-over device has a piston moved in response to a change in hydraulic pressure in a hydraulic pressure chamber. A roller shaft is disposed on at least one of the cam followers and has a roller carried thereon to come into rolling contact with a valve operating cam. In this valve operating system, the hydraulic pressure chamber and a communication passage, which permits an oil supply passage to communicate with the hydraulic pressure chamber, are defined in a particular one of all the cam followers, which moves a smallest amount when the connection switch-over device is in its disconnecting state. The roller shaft, having the roller rotatably carried thereon, is mounted on the cam follower other than the particular one cam follower.          Thus, it is possible to avoid an increase in size of the particular one cam follower, and avoid a complicated assembling operation and passage construction. Moreover, the valve operating load is reduced to a minimum by using the roller.

Abstract: A flywheel energy conversion device (10) provides highly efficient conversion between kinetic and electrical energy. The flywheel (10) produces increased output by providing armature coils (44) in an air gap (46) formed about the flywheel (both radial and axial embodiments are described). In preferred embodiments, field coils (30, 32) of a magnetic circuit are energized with DC  drive current that creates homopolar flux within a rotating solid rotor (12) having teeth (14) cut from a flat disk. The total reluctance of the magnetic circuit and total flux remain substantially constant as the rotor rotates. The flux may travel radially outward and exit the flat disk through the teeth (14) passing across an armature air gap (46). Air gap armature coils (44) are preferably utilized in which the changing flux density (due to the rotating teeth) induces an output voltage in the coils. The flux is diffused before returning to the rotor in one of several ways such that core losses are effectively reduced, thereby enabling the flywheel to operate efficiently at high frequencies.
