    • A voltage-controlled oscillator has: an LC resonant circuit including an inductor and a variable capacitor that are connected in parallel between a pair of output terminals; a plurality of negative resistance circuits provided between a power source and the LC resonant circuit; a plurality of capacitor groups; a first switch circuit selecting an arbitrary number of negative resistance circuit from the plurality of negative resistance circuits; and a second switch circuit selecting an arbitrary number of capacitor group from the plurality of capacitor groups. The LC resonant circuit and the selected capacitor group constitute a resonant circuit. The resonant circuit is electrically connected to the power source through the selected negative resistance circuit, oscillates at an oscillation frequency depending on total capacitance of the resonant circuit, and outputs a differential signal of the oscillation frequency from the pair of output terminals.

    • A vehicle door lock device consists of a striker and a lock body. The striker has a pair of straight leg portions and arc shape portions, respectively formed at end portions of the leg portions. The lock body has a guide groove through which the striker proceeds or moves, a latch adapted to engage with the striker entering the guide groove, a ratchet keeping an engaged condition of the latch and striker, and a resilient stopper positioned at an end of the guide groove. The stopper has a first abutting portion against which the straight leg portion abuts and an arc shape second abutting portion against which the arc shape portions of the striker abuts. The leg portion abuts against the first abutting portion when the latch of the lock device situates at its mid position between the half latched position or condition and the full latched position or condition of the latch. While, the arc shape portion of the striker and the second abutting portion of the stopper abuts against each other, when the lock device or latch situates at its full latched position. The first abutting portion and/or the second abutting portion have groove portions of arc shape in section, improving a contact efficiency of the stopper and the striker.
    • 车门锁装置由撞针和锁体构成。 撞针具有分别形成在腿部的端部处的一对直脚部分和弧形部分。 锁体具有引导槽,撞针进入或移动,引导槽,适于与进入引导槽的撞针接合的闩锁,保持闩锁和撞针的接合状态的棘轮,以及位于 导槽。 止动件具有第一邻接部分和直脚部分邻接的第一邻接部分和撞击件的弧形部分邻接的弧形第二邻接部分。 当锁定装置的闩锁位于半锁定位置或状态与闩锁的完全锁定位置或状态之间的中间位置时,腿部抵靠第一邻接部分。 而当撞针的弧形部分和止动件的第二抵接部分彼此抵接时​​,当锁定装置或闩锁位于其完全锁定位置时。 第一抵接部和/或第二抵接部具有圆弧状的槽部,提高止动器和撞针的接触效率。
