摘要： A drowsiness detecting apparatus has a pulse wave sensor and a determination circuit. The sensor is provided to a steering wheel to detect a pulse wave of a vehicle driver gripping the steering wheel. The determination circuit generates a thorax pressure signal indicative of the depth of breathing by envelope-detecting a pulse wave signal of the sensor and determines whether the driver is drowsy by comparing a pattern of the thorax pressure signal with a reference pattern. The display and the buzzer notify the driver and any other passengers in the vehicle of the drowsiness of the driver by a visual indication and buzzing sound, respectively. A body surface motion may be used as a signal that indicates the depth of breathing.

摘要： In a swash plate type axial piston pump, a swash plate 23 is fixed and supported in a cabinet while being inclined with respect to the center axial line of a rotary shaft 3. A cylinder block 15 having a plurality of cylinders 13 is attached to the rotary shaft 3 so that the cylinder block 15 slides of the rotary shaft 3 in the axial direction thereof and is rotated integrally therewith. Each one end of a plurality of pistons 21 is slidingly engaged with the cylinder 13 and the other end thereof is abutted against the swash plate 23 through a shoe 25. A valve plate 31 having a suction port 33 and a discharge port 35 is disposed so as to be abutted against the inner surface of the cabinet 1 and the bottom the cylinder block 15 so that a suction path 39 and a discharge path 41 in the cabinet 1 are selectively communicated with a pump chamber 14 in each cylinder through the suction port 33 and the discharge port 35. An operating oil is supplied to the sliding portion between the valve plate 31 and the bottom of the cylinder block 15 by a lubrication means. With this arrangement, since the operating oil is positively supplied to the sliding portion being rotated of the swash plate type axial piston pump, the sliding portion is sufficiently lubricated even if the pump is started to thereby prevent the dry state of the pump.

摘要： A high-pressure fuel supply pump with high performance is capable of securely preventing a cylinder section from seizing up and also permits improved sealing performance to minimize the chance of fuel leakage. The high-pressure fuel supply pump has: a casing (48) having a cylindrical cavity (48a); a sleeve (40) which has a cylinder section (40a) and a fixing section (40c), one end thereof closer to the fixing section (40c) being abutted against the bottom of the cavity (48a); and a piston (53) which is disposed in the cylinder section (40a). The high-pressure fuel supply pump takes in fuel through an intake passage (36) by the reciprocation of the piston (53) into a fuel pressurizing chamber (52) to pressurize it, then discharges the pressurized fuel through a discharge passage (37) to forcibly feed it into a fuel injector of a cylinder injection engine. A cylindrical slit (40d) is provided between the cylinder section (40a) and the fixing section (40c) of the sleeve (40), and the fixing section (40c) is secured by being fastened toward the bottom of a cavity (48a) by a cylindrical fastening member (64) screwed to the cavity (48a).
