摘要:
The present invention provides a multi-cylinder engine capable of inhibiting an EGR cooler from being damaged and at the same time making the EGR cooler compact. On the assumption that a direction where a crank shaft spans is taken as a front and rear direction and a widthwise direction of a cylinder head perpendicular to this front and rear direction is deemed as a lateral direction, an intake-air distributing passage wall is attached to one lateral side surface of the cylinder head and an exhaust-gas converging passage wall ached to the other lateral side of the cylinder head, the exhaust-gas converging passage wall having an interior area communicated with an interior area of the intake-air distributing passage wall through the EGR cooler. In this multi-cylinder engine, an intake-air inlet pipe is made to stand up at an upper portion of the intake air distributing passage wall and the EGR cooler is above the intake-air distributing passage wall. Further, the intake-air inlet pipe is arranged side by side with the EGR cooler.

The present invention provides a multi-cylinder engine capable of inhibiting an EGR cooler from being damaged and at the same time making the EGR cooler compact. On the assumption that a direction where a crank shaft spans is taken as a front and rear direction and a widthwise direction of a cylinder head (2) perpendicular to this front and rear direction is deemed as a lateral direction, an intake-air distributing passage wall (3) is attached to one lateral side surface of the cylinder head (2) and an exhaust-gas converging passage wall (4) is attached to the other lateral side of the cylinder head (2), the exhaust-gas converging passage wall (4) having an interior area communicated with an interior area of the intake-air distributing passage wall (3) through the EGR cooler (6). In this multi-cylinder engine, an intake-air inlet pipe (5) is made to stand up at an upper portion of the intake-air distributing passage wall (3) and the EGR cooler (6) spans above the intake-air distributing passage wall (3). Further, the intake-air inlet pipe (5) is arranged side by side with the EGR cooler (6).

A press-fit portion (24) of a press-fit pin (22) is constructed by cutting and outwardly pushing a band-like region (24a), which is placed in the vicinity of the widthwise center of a pin material, in one of orientations of the thickness direction in such a way as to project from peripheral regions (24b) of the band-like region (24a). At that time, the thickness dimension (W3) of the press-fit portion (24) is set to be equal to or less than that W1 of a pin body (23).
摘要:
A power window apparatus that inhibits leakage current when submerged in water. The power window apparatus includes an operation switch. A microcomputer controls a motor. A connector has a down terminal and an up terminal connecting the operation switch and the microcomputer, and a ground terminal used to connect the operation switch and the ground. When operated, the operation switch connects the down terminal or the up terminal to the ground terminal and generates a low-level input signal in the down terminal or in the up terminal. The microcomputer drives the motor in response to the low-level input signal. An inhibition mechanism arranged in the connector inhibits, when water enters into the connector, a leakage current from flowing between a connecting terminal and a ground terminal.

A printed-wiring board is incorporated into an electronic device housing constructed of a conductive member, and has a ground pattern. A metal plate having a size equal to or larger than the printed-wiring board is disposed in a position facing to the printed-wiring board. The metal plate has a characteristic impedance corresponding to an electric characteristic and a relative position to the printed-wiring board. A connecting member electrically connects the ground pattern of the printed-wiring board to the metal plate, and includes an impedance element having a value substantially equal to the characteristic impedance between the printed-wiring board and the metal plate. An occurrence of radiant noises caused by standing-waves etc. is thereby prevented. A conductive layer having the ground pattern of the printed-wiring board may be connected to another conductive layer provided instead of the metal plate and including a conductive member of which an area is substantially equal to the former conductive layer, with an impedance element interposed between these conductive layers.

When a knob is operated, operating force is exerted on an operating point Pm of the manual switch and an operating point Po of the automatic switch from a pusher, and thus the manual switch and the automatic switch are pushed and turned on sequentially. In this case, since the height H of the pusher is set ‘0.9 times’ or more of the distance Lmo from the operating point Pm of the manual switch to the operating point Po of the automatic switch, the pusher has a vertically long shape. As a result, the operating force of the knob is influenced by the friction when the automatic switch is pushed and turned on. Therefore, the manual switch and the automatic switch can be pushed and turned on sequentially while using the automatic switch having small self-holding force Fo.
摘要:
A method for producing a magnetic particle forming a magnetic material for absorbing electromagnetic waves comprises the steps of mixing an organometallic complex or a metal salt with a chain polymer and dissolving the mixture in a solvent (step S1); raising the temperature of the mixture to reaction temperature (step S2), carrying out a reaction at the reaction temperature (step S3); and forming the magnetic particle having a structure that the periphery of each fine particle formed from the organometallic complex or the metal salt is surrounded by the chain polymer and recovering the formed magnetic particle after the reaction (step S4). The magnetic particle has a nanogranular structure to become a magnetic material for absorbing electromagnetic waves. Such a magnetic particle is produced by a wet reaction. Thus, a larger amount of magnetic particle can be produced by one reaction.

A heater control unit of a dial type installed on an instrument panel and functioning as an operation portion of an air conditioner equipped in an automobile. The first bevel gear is integral with the shaft coupled with a dial. The first and second supports are integral with the base member. The first support is sectionally crank-shaped and the upper support wall thereof is disposed at the outside of the lower support wall with respect to the second support. The upper support wall has an approximately semi-circular upper support surface for receiving a portion of the shaft upper than the axis thereof, and the lower support wall has an approximately semi-circular lower support surface for receiving a portion of the shaft lower than the axis thereof. The distance between the inner surface of the lower support wall of the first support and the inner surface of the second support is longer than the distance between an end surface at the second support side of the shaft and an end surface at the first support side of the first bevel gear. The distance between the inner surface of the upper support wall of the first support and the inner surface of the second support is shorter than the entire length of the shaft.
