Abstract:
A surface of a fixed scroll which is opposed to a end plate of an orbiting scroll existing outside of a lap of the fixed scroll is formed with: a substantially annular seal portion which extends such as to have an outer wall surface of the fixed scroll outwardly extending from an inner wall surface of outermost periphery of the lap substantially along the inner wall surface, and which comes into slide contact with the end plate of the orbiting scroll; a substantially annular recess located outside of the substantially annular seal portion; and a recess which is brought into communication with an intake port of the fixed scroll independently from the substantially annular recess. With this, back pressure of the orbiting scroll is increased, and turning-over phenomenon of the orbiting scroll can be suppressed.
Abstract:
In a solid-state image-sensing device, by global shuttering, whereby image sensing is performed simultaneously in all the pixels, a potential commensurate with the amount of light incident on a buried diode PD is held in an N-type floating diffusion region FD. Then a noise signal is outputted, and then the potential held in the N-type floating diffusion region FD is transferred to an N-type floating diffusion region FD1 so that an image signal is outputted.
Abstract:
The plasma display device has pixels each formed by a plurality of sub pixels of the same color provided in an address-electrode direction, and provides gray-scale display by controlling the number of sub pixels to be turned ON. A plurality of address electrodes are provided for each sub pixels. Each sub pixel is addressed by a conductive layer which is electrically connected to one of the plurality of address electrodes.
Abstract:
A vehicular automatic transmission for establishing a plurality of forward gear stages, includes: a transmission case; an input shaft; a transmission mechanism connected to the input shaft and including a plurality of transmission elements; an output shaft connected to the transmission mechanism; first and second clutches at opposite ends of the transmission mechanism and drivably connecting the input shaft with at least one of the transmission elements; and first and second hydraulic servos for applying the first and second clutches responsive to feed of an oil pressure. The transmission case encloses the transmission mechanism, the clutches and the hydraulic servos, and includes axial end walls forming cylinders for the hydraulic servos. First and second bearings are arranged between the pistons of the hydraulic servos and the first and second clutches, respectively, for allowing the relative rotation between the pistons and the clutches and for transmitting the thrust forces from the pistons to the respective clutches.
Abstract:
A scroll compressor includes a stationary scroll member accommodated in a closed housing and having a stationary end plate and a stationary scroll wrap protruding axially from the stationary end plate, and also includes an orbiting scroll member accommodated in the closed housing and having an orbiting end plate and an orbiting scroll wrap protruding axially from the orbiting end plate so as to engage with the stationary scroll wrap to define a plurality of working pockets therebetween. A volume ratio indicating a ratio of the volume of the working pockets at an end of suction to that at an end of compression is set to be smaller than a value corresponding to a compression ratio determined by an evaporation pressure and a condensation pressure at a performance half a rated performance during heating.
Abstract:
Smooth driving of a vehicle is achieved by eliminating busy shift by providing a small gear ratio step between the two highest gear ranges while maintaining structural compactness of the transmission. In the second highest gear range or state, a first pinion P1 has a diameter smaller than that of a second pinion P2, both pinions P1 and P2 being coupled integrally and at least partially determining the second highest gear ratio. The gear ratio .lambda..sub.2 in the second highest gear range is described as 1+(Z.sub.S2 /Z.sub.R1).times.(Z.sub.P1 /Z.sub.P2). Since (Z.sub.P1 /Z.sub.P2) is always equal to 1.0 or less, the gear ratio can be made smaller without enlarging the diameter of the ring gear R1 significantly to decrease the gear ratio step to the highest gear range.
