  • Patent number: 10787219
    Abstract: An electric vehicle drive device includes a swing arm including an arm portion disposed on a left side, having a front part pivotally supported by a pivot shaft, and including a main wall having a height and extending in a front-rear direction, and a cross arm portion which has a front part pivotally supported by the pivot shaft, and including a coupling portion extending toward the left side to the main wall. A guide hole penetrating through the main wall in a vehicle width direction is formed between a part pivotally supported by the pivot shaft and a part in which the coupling portion extends. A harness extends along a side of the main wall on the left side, passes through the guide hole, and extends along the cross arm portion.

  • Patent number: 5694092
    Abstract: A Colpitts voltage-controlled oscillator is provided with a variable capacitance section 11 connected in parallel to a resonator 12, which is the inductance element of an inductance section 1. Variable capacitance section 11 is provided with varactors X1 and X2 having differing voltage/capacitance ratios. A fixed control voltage Vc is applied to the commonly connected cathodes of varactors X1 and X2. A control voltage Va which produces a reverse bias voltage (Vc-Va) is applied to the anode of varactor X1, and a control voltage Vb which produces a reverse bias voltage (Vc-Vb) independent of control voltage Va is applied to the anode of varactor X2. When control voltage Va is fixed, control voltage Vb is made the frequency control signal, and when control voltage Vb is fixed, control voltage Va is made the frequency control signal.
