Abstract: An electric connector includes at least one terminal pin having, at opposite ends thereof, terminals to be inserted into through-holes formed through printed circuit boards spaced away from and facing each other, and an aligner for aligning the terminal pins in a row in such a condition that the terminal pins are movable relative to the aligner, the terminal pin including a movement-limiter which restricts movement of the terminal pin in a direction of an axis thereof.

Abstract: A construction vehicle includes a cooling device. The cooling device includes a radiator disposed on a vehicle body frame, an oil cooler disposed adjacent to the radiator with a rear surface side thereof being arranged to face in roughly parallel to a lower part of a front surface of the radiator, and an opening/closing mechanism including a rotary shaft. The rotary shaft is obliquely disposed with a top end portion thereof being arranged closer to the front surface of the radiator than a bottom end portion thereof is. The opening/closing mechanism is configured to pivot the oil cooler about the rotary shaft and simultaneously move the oil cooler with respect to the radiator. Either a counterweight mounted on a rear part of the vehicle body frame or a part of the vehicle body frame is disposed on a line horizontally extended from a bottom end portion of the oil cooler.

Abstract: The press-fit type connector terminal includes a pin section in the form of a flat plate, and a plurality of contact sections situated continuous to a front end of the pin section, each of the contact sections including a contact piece being in the form of a barrel or a spindle surrounding an imaginary center line, the contact piece being formed with a slit extending substantially parallel to the imaginary center line, the connector terminal being comprised of a single bent metal plate having elasticity.

Abstract: A cooling device (20) mounted on a wheel loader (10) includes a radiator (22), an oil cooler (23), an after-cooler (24), air conditioner condenser (25) and a fuel cooler (26). An opening/closing mechanism (31) for pivoting the oil cooler (23) is configured to pivot the oil cooler (23) to a position at a predetermined opening angle about a pivot shaft (31a) disposed in the vicinity of the right end of the front surface of the oil cooler (23). The rotary shaft (31a) is disposed while being slanted at an angle ? with respect to the vertical direction in the back-and-forth direction of a vehicle body (11).

Abstract: A trigger source switching circuit including a first switch system for a high frequency region, and a second switch system for a low frequency region. The first switch system is composed of a plurality of semiconductor switches having good frequency and isolation characteristics, and the adverse effect of the DC shift is eliminated by using a capacitor connected between the outputs of the semiconductor switches and the output terminal of the trigger source switching circuit. The second switch system for the low frequency region is composed of analog switches, and the output terminal of each analog switch is connected to an input terminal of an operational amplifier of a small output offset, thereby reducing the effect of the on-resistance of the analog switches and the adverse effect of the DC shift. The analog switches can be used because the frequency and isolation characteristics required in the high frequency region are unnecessary in the low frequency region.
