The present invention provides as tarter capable of keeping a state where a pinion and a ring gear maintain meshing with each other when an engine stops without providing a plunger stopper using a solenoid or the like. The state where the pinion and the ring gear maintain meshing with each other in the engine stop mode continues by movement resistance which occurs when a torque transmission member moves. Concretely, an inclination angle of a helical spline in a helical spline engagement part is set so that the above state continues. The helical spline engagement part is a part where a helical spline on the outer periphery of an output shaft of a starter motor and a helical spline on the inner periphery of the torque transmission member mesh with each. Consequently, the above state continues without a plunger stopper using a solenoid or the like.

Micromechanical structures having at least one lateral capacitive transducer gap filled with a dielectric and method of making same are provided. VHF and UHF MEMS-based vibrating micromechanical resonators filled with new solid dielectric capacitive transducer gaps to replace previously used air gaps have been demonstrated at 160 MHz, with Q's˜20,200 on par with those of air-gap resonators, and motional resistances (Rx's) more than 8× smaller at similar frequencies and bias conditions. This degree of motional resistance reduction comes about via not only the higher dielectric constant provided by a solid-filled electrode-to-resonator gap, but also by the ability to achieve smaller solid gaps than air gaps. These advantages with the right dielectric material may now allow capacitively-transduced resonators to match to the 50-377Ω impedances expected by off-chip components (e.g., antennas) in many wireless applications without the need for high voltages.

An electrostatic transducer for micromechanical resonators, in which the electrode gaps are filled with a dielectric material having a much higher permittivity than air. This internal electrostatic transducer has several advantages over both air-gap electrostatic and piezoelectric transduction; including lower motional impedance, compatibility with advanced scaled CMOS device technology, and extended dynamic range. In one aspect, in order to minimize energy losses, the dielectric material has an acoustic velocity which is matched to that of the resonator material. Internal electrostatic transduction can be adapted to excite and detect either vertical modes (perpendicular to the substrate) or lateral modes (in the plane of the substrate). Its increased transduction efficiency is of particular importance for reducing the motional resistance of the latter.
