    摘要: A semiconductor package includes a first insulating substrate, a second insulating substrate, and a plurality of semiconductor chip units placed between the first and second insulating substrates. The first insulating substrate has wiring placed on one surface thereof and has first electrically conductive balls which are used as external connection terminals and second electrically conductive balls which radiate heat. The first and second electrically conductive balls are on the other surface thereof. The second insulating substrate is placed opposite to the one surface of the first insulating substrate. Each semiconductor chip unit has a semiconductor chip; a circuit board which has the semiconductor chip mounted thereon and wiring electrically connected to terminals of the semiconductor chip; and a third insulating substrate which is placed on the circuit board and which has a chip cavity for housing the semiconductor chip. By use of the second electrically conductive balls placed on the first insulating substrate, beat generated in the semiconductor chip is efficiently released outside, thus preventing an increase in temperature of the semiconductor chip.

    摘要: An infinitely variable transmission in which the pitches of a driving pulley and a driven pulley are variable by means of hydraulic fluid pressure to vary the velocity ratio between the two pulleys. A lower pressure fluid and a higher pressure fluid are created from a hydraulic fluid from a hydraulic fluid supply source, with a constant pressure difference therebetween. The lower pressure fluid has its pressure value varied in response to the velocity ratio. The lower pressure fluid and the higher pressure fluid are selectively supplied to the movable pulley elements of the driving pulley and driven pulley. A hydraulic clutch and a pressure regulating valve are connected together by a hydraulic fluid supply passageway which is selectively closed and opened by a supply control valve. A drain passage is connected to the hydraulic fluid supply passageway to allow hydraulic fluid to escape from the hydraulic clutch when the passageway is closed by the supply control valve. In at least one movable pulley element, an orifice is formed through a sealing element which seals between an inner peripheral surface of a cylindrical portion and a radially extending annular flange of a stationary piston element to communicate between first and second hydraulic pressure chambers defined within an annular space in a pulley main body at opposite sides of the annular flange of the stationary piston element.

    摘要: An infinitely variable transmission includes a driver shaft having a driver pulley, a driven shaft having a driven pulley, the driver and driven pulleys having fixed conical discs and movable conical discs, the movable conical discs having pressure chambers, an endless belt trained around said driver and driven pulleys, a device for supplying a fluid under pressure to the pressure chambers, a pressure regulating mechanism for regulating the fluid pressure at a prescribed pressure, and a fluid metering mechanism for regulating the amount of the fluid under the prescribed pressure in the pressure chambers. At least one of the pressure regulating mechanism and the fluid metering mechanism is disposed in the driver shaft or the driven shaft. The pressure regulating mechanism is arranged to discharge an excess amount of the fluid to a lower-pressure area when the supplied fluid pressure exceeds a prescribed level and also has passages for supplying the discharged amount of the fluid as lubricating oil to the endless belt. The fixed conical discs of the driver and driven pulleys are disposed on opposite sides of the endless belt. The fixed conical discs are arranged such that the central axis of the endless belt is inclined with respect to a line normal to pulley axes at an angle which is substantially zero at a power transmission speed ratio which is most frequently be used between the driver and driven pulleys.

    摘要: A hydraulic servomechanism comprises a basic body having an axial hole formed therein, a stationary element provided on the outer peripheral surface of the basic body at a predetermined location, a sliding element fitted on the outer peripheral surface of the basic body and also fitted with the stationary element for axial sliding movement relative thereto. The sliding element cooperates with the basic body and the stationary element to define therebetween a hydraulic pressure chamber. A plurality of through bores are formed in the peripheral wall of the basic body and axially arranged at predetermined intervals for communicating between the axial hole of the basic body and the hydraulic pressure chamber. A communication hole is formed in the sliding element for communicating between the through bores and the hydraulic pressure chamber. A control element is axially slidably fitted in the axial hole of the basic body and formed therein with a first communication passage for communicating the through bores with a hydraulic fluid supply source which generates the pressure of hydraulic fluid supplied to the hydraulic pressure chamber, and a second communication passage for communicating the through bores with a zone under a lower pressure. A driving device changes the axial position of the control element for controlling the pressure of hydraulic pressure within the hydraulic pressure chamber, to thereby control the axial position of the sliding element.

    摘要: A neutral apparatus for use on an electric vehicle is disclosed. The neutral apparatus comprises a control state detector and a neutral mechanism control circuit. The control state detector detects whether or not the motor control unit is in a predetermined control state. The neutral mechanism control unit can instruct the neutral mechanism to interrupt the power train according to the output signal from the control state detector. If the motor control unit is not in the predetermined control state, this is detected by the control state detector. In response to the output signal from the control state detector, the neutral mechanism control circuit causes the neutral mechanism to interrupt the power train. Thus, power flow from the motor to the drive wheels is interrupted. The control state detector is comprised of a voltage comparator circuit for comparing the output voltage from the motor driver circuit with a reference voltage and produces an output signal. As a result, it becomes possible to monitor the control state of the vehicle during movement thereof by means of an arrangement simple in construction.
