Abstract:
Between an exhaust chamber and a lubrication chamber, a second seal that seals between a cylinder that partitions the exhaust chamber and a first shaft and a first seal that seals between a side cover that partitions the lubrication chamber and the first shaft are provided. A gas introduction space to which a seal gas is supplied is provided between the second seal 2 and the first seal. The second seal and the first seal each have a base part and a pair of ring-like lips extending from the base part toward the first shaft. The pair of lips extends such that the distance therebetween is gradually increased from the base part toward the first shaft, and the tips of the pair of lips can be brought into elastic contact with the first shaft.

Abstract:
A light source 165 of a projection unit 16 AM modulates an electric current supplied to a built-in LED. The projection unit 16 projects the modulated light on a projection screen. A photoreceiver 171 receives, with a time lag, a reflected portion of the modulated light from the screen, which corresponds to a time required for the light to travel from its projection to its reception. A calculation unit 173 acquires a phase difference between the projected light and its reflection at a respective one of a plurality of points on the screen, acquires a distance from the projector to the respective one of the plurality of points on the screen, and then acquires an inclination angle of the screen. Because the distance from the projector to a respective one of the plurality of points on the screen is acquired based on the corresponding phase difference, the measurement accuracy is improved compared to the triangular distance measuring method. The projector requires no distance measurement-only light source, thereby reducing the size of the projector.
Abstract:
In automatic shift control apparatus and method for a manual transmission, at least one clutch is interposed between an engine and the manual transmission and a controller performs a feedback control for an engagement force of the clutch after a gear shift for the manual transmission is ended in such a manner that an input revolution speed of the clutch is directed toward another revolution speed thereof after the gear shift occurs at a predetermined time variation rate, the controller setting mutually different feedback control gains in a variation region of the input revolution speed of the clutch in which the input revolution speed of the clutch is directed toward the other revolution speed after the gear shift occurs and in a convergence region of the input revolution speed in which the input revolution speed of the clutch has reached to the other revolution speed after the gear shift occurs.
Abstract:
A field sequential color projector includes an area sensor unit having an area sensor for photographing a screen, and an optical filter for permitting only a red light having the same color as a laser beam from a laser pointer to be input to the area sensor, and a color period/timing extraction unit which extracts timings for projecting red, green, and blue images. When a projection timing for a red image arrives while an image is projected, an MPU (Micro Processor Unit) receives a light of an image projected on the screen at that time to acquire image information, and detects a position pointed by the laser beam based on the acquired image information. Even if there exists a portion having the same color as the laser beam in the projected image, a pointed position detection device accurately detects the position irradiated by a pointing light of the laser pointer.
Abstract:
A hybrid vehicle comprises a drive wheel (5), an internal combustion engine (1), a power generating motor (2) that generates an electric power by using an output power of the engine (1), and a planetary gear set (13) that comprises a combination of a gear element that is driven by the engine (1), a gear element that is connected to the power generating motor (2), and a gear element that is connected to the drive wheel (5). A target engine power is computed based on an accelerator operation amount. The engine (1) is controlled based on the target engine power. And control a rate of variation in the rotation speed of the engine (1) to be smaller, when the rotation speed of the power generating motor (2) increases than when the rotation speed of the power generating motor (2) decreases toward zero as a result of controlling the engine (1) based on the target engine power. Fuel consumption rate is thus improved.
Abstract:
The present invention pertains a controlling scheme for brake torque, which is applied, as a stand-by braking torque, to wheels of an automotive vehicle upon determination that operator braking action is imminent. A braking system applies brake torque in response to a brake signal The brake torque applied to the vehicle is monitored and the brake signal is modified based on the monitored brake torque to alter the brake torque.
Abstract:
The present invention pertains a controlling scheme for build-up or variation rate at which brake pressure increases till completion of pressure build-up for stand-by brake torque. Stand-by brake torque control begins with recognition of emergency or occurrence of operator reaction or quick release of accelerator. During initial stage of the stand-by brake control, brake pressure increases till completion of pressure build-up for stand-by brake torque before vehicle operator depresses a brake pedal. Build-up or variation rate at which brake pressure increases till completion of pressure build-up for stand-by brake torque is determined in response to time left before the operator depresses the brake pedal. Period of time left before the operator depresses the brake pedal varies with differing events that have initiated the stand-by brake torque control.

In preceding vehicle following control apparatus and method for an automotive vehicle, a vehicular velocity controller includes a target inter-vehicle distance calculating section that calculates a target inter-vehicle distance from the vehicle to a preceding vehicle detected by an inter-vehicle distance sensor on the basis of a vehicular velocity detected by a vehicular velocity detector and an inter-vehicle distance detected by an inter-vehicle distance detector, a first vehicular velocity controlling section that performs a vehicular velocity control to bring the detected inter-vehicle distance substantially coincident with the target inter-vehicle distance, and a vehicular deceleration stopping section that performs a vehicular deceleration control to stop the vehicle in accordance with the inter-vehicle distance from the vehicle to the preceding vehicle immediately before a time point at which the inter-vehicle distance detector which trapped the presence of the preceding vehicle has not detected the preceding vehicle when the detected vehicular velocity falls in a low vehicular velocity region lower than a predetermined velocity value and -the inter-vehicle distance detector which trapped the presence of the preceding vehicle has not detected the preceding vehicle.
