    摘要: An output circuit includes a plurality of output buffer circuits and a plurality of pre-buffer circuits connected to drive the output buffer circuits. Some of the pre-buffer circuits are each constituted by P- and N-channel MOS transistors having channel widths or channel lengths which are large enough to drive the output buffer circuits, and the remaining pre-buffer circuits are each constituted by P- and N-channel MOS transistors whose channel widths and channel lengths are so determined as to set the current driving ability thereof sufficiently smaller than that of the corresponding output buffer circuits.

    摘要: A variable displacement pump includes: a rotor mounted in a body; a cam ring mounted radially outside of the rotor, and arranged to move with a change in an eccentricity of the cam ring with respect to the rotor, wherein change of the eccentricity causes a change in a specific discharge rate; and an electromagnetic actuator arranged to actuate the cam ring for regulating the eccentricity. During control of operation of the electromagnetic actuator, a first response is set slower than a second response, wherein the first response is a response of movement of the cam ring to a change of an input signal in a direction to request a decrease in the specific discharge rate, and the second response is a response of movement of the cam ring to a change of the input signal in a direction to request an increase in the specific discharge rate.

    摘要: A variable displacement pump including a drive shaft, a cam ring eccentrically moveable with respect to an axis of the drive shaft, and a solenoid drivingly controlled on the basis of variation in electric current amount to be supplied to the solenoid which is controlled in accordance with an operating condition of a vehicle. The solenoid is configured such that a rate of change in the specific discharge amount relative to the electric current amount to be supplied to the solenoid under a condition that the specific discharge amount is smaller is reduced as compared to a rate of change in the specific discharge amount relative to the electric current amount to be supplied to the solenoid under a condition that the specific discharge amount is larger.

    摘要: A process for manufacturing a quartz crystal element consists of the steps of producing plural quartz layers on a surface of a crystalline substrate having a lattice constant differing from that of quartz crystal, in which each of the quartz layers consists of a crystalline phase and an amorphous phase, and percentage of the crystalline phase in the quartz layer farther from the substrate is larger than percentage of the crystalline phase in the quartz layer adjacent to the substrate; and producing an epitaxially grown quartz crystal film on the surface of the quartz layer farther from the substrate by a reaction between silicon alkoxide and oxygen.
