An ECU for determining whether a request for acceleration is made to a supercharged internal combustion engine includes an acceleration request determining unit that determines whether a pressure difference between the upstream pressure and downstream pressure of a throttle valve disposed in an intake system is equal to or smaller than a predetermined value, and determines that a request for acceleration is made when the pressure difference is equal to or smaller than the predetermined value. The ECU also includes a variable valve actuating mechanism control unit that controls an InVVT and an ExVVT so that the intake charging efficiency and output torque of the engine become equal to the maximum intake charging efficiency and output torque at a certain downstream pressure when the acceleration request determining unit determines that a request for acceleration is made.

A rolling bearing assembly includes: an outer member 10 possessing outer raceways 11, 12 on an inner periphery thereof; an inner member 20 possessing inner raceways 21, 22 formed on an outer periphery thereof and opposing the outer raceways 11, 12, and including a shaft body 3 of the bearing assembly; rolling elements 4 interposed between the inner raceways 21, 22 and the outer raceways 11, 12 in opposing relation; a wheel-mounting flange 5 disposed on an outer periphery of the outer member 10; and a brake rotor 7 mounted to the outer periphery of the outer member 10 without relying on the wheel-mounting flange 5 as allowed to move axially in a predetermined axial range relative to the outer member 10 but inhibited from moving circumferentially. Thus, the bearing assembly achieves unitization at reduced manufacture costs and is capable of effectively suppressing brake judder.

Power of an engine is divided to be transmitted to a power transmission path to front wheels and a power transmission path to rear wheels by a transfer mechanism where the power has just passed through a transmission so as to be transmitted to front wheels and rear wheels. In addition, a torque reduction and transmission joint is provided on the power transmission path to the rear wheels, so that the rotational drive torque to the rear wheels is reduced to be transmitted thereto. Additionally, constant velocity joints which are provided on the power transmission path to the rear wheels are configured to have a smaller torque transmission capacity and a smaller size than those of constant velocity joints which are provided on the power transmission path to the front wheels.

An electrostatic deflector that can be manufactured easily and very accurately without using a member for positioning is provided. After multiple slits 81d to 88d have been formed in the same direction as that of the bus bar of an approximately conical electrode material 100 whose large-diameter section is formed with flange portions 81a to 88a for installation on an insulator 90, each of the flange portions is coupled with the insulator 90, then the electrode material 100 is cut along extension lines of the slits 81d to 88d, and thus, multiple electrode members electrically isolated from one another are formed.

An image sensor 1 includes a glass substrate 10, a plurality of photoelectric converting elements 20 made of an organic material, a plurality of IC chips 30 on which driving circuits made of single crystal silicon are respectively mounted, and wirings 40 which connect the plurality of photoelectric converting elements 20 to the respective driving circuits mounted on the IC chips 30. The plurality of photoelectric converting elements 20 are integrally and seamlessly formed with a predetermined arrangement pitch over a predetermined sensor length. The arrangement pitch of a plurality of detecting means formed on the driving circuits mounted on the IC chips 30 is equal to or less than that of the photoelectric converting elements.

A seal apparatus comprises an outer ring side seal ring fixed to an outer ring member, and an inner ring side seal ring fixed to an inner ring member. A pulser ring is fixed to a ring shaped core metal of the inner ring side seal ring. On an outer diameter side of the ring shaped core metal of the outer ring side seal ring, a magnetic sensor is molded with resin by an external member to be integrated therewith. A connector connected to the magnetic sensor is successively formed with the external member. A reinforcing member which reinforces the sensor side connector is provided on at least either of the external member or the sensor side connector.

An outer ring 3 is provided with the stator 7 of a resolver 2, and a ring member 4 with the rotor 8 of the resolver 2. The stator 7 comprises an annular core 9 and a winding 10 provided around the core 9. The ring member 4 is provided at a position opposed to the stator 7 with an eccentric cylindrical face serving as the rotor 8 and eccentric with respect to other outer peripheral surface of the ring member 4.

An endoscope 10 comprises an insert portion 30 having outer tubing 35, a light guide 31, an image guide 32 and an objective optical member 33. Peripheral side surfaces of these components 31,32,33,35 adjacent to each other are bonded together by an adhesive 36 at a distal end portion of the insert portion 30. The adhesive 36 contains fine particles 36b comprising a roentgenopaque material such as Pt or Au. The adhesive 36 fills among optical fibers 31a inside the light guide 31, thereby roentgenopaque property is conferred not only among the above-mentioned components 31,32,33,35 at the distal end of the insert portion 30 but also on the inside of the light guide 31. This enables the distal end of the endoscope 10 to be traced with X-rays without enhancing the diameter of the insert portion 30. Therefore, the endoscope 10 can easily be inserted into human small vessels such as blood vessels.

A vehicle-use bearing device having a double row rolling bearing fitted around an outer peripheral surface of a hollow shaft portion of a hub wheel, wherein a held portion between an axially intermediate position and a vehicle outer side in the hollow shaft portion of the hub wheel is axially held between the axially intermediate position of an outer ring shaft portion of a constant velocity joint and the vehicle outer side so that a cup-shaped cylindrical portion of an outer ring of the constant velocity joint is free of contact with a caulked portion in the hollow shaft portion of the hub wheel at the shaft end on the vehicle inner side in order to connect the hub wheel with the constant velocity joint without a clearance, whereby an excessive preload which can affect a rolling performance of the double row rolling bearing is not imparted on the bearing.

Sensor-equipped hub units 34a attached to respective drive wheels 34 each have a sensor device comprising a sensor 36 for detecting the ground contact load on the wheel 34. A control unit 31 has a traction controller 32, whereby when the ground contact load value output from one of the ground contact load sensors 36 while the vehicle is traveling straight is outside a predetermined range, the drive wheel 34 is controlled so as to return the ground contact load value to the original value.
