摘要： A piezoelectric tuning fork vibrator used as an oscillator or a detection element in various electronic circuits, which is provided at a vibrator body with a slit to form tuning fork legs at both sides, one leg at the vibrator having at the outside surface a piezoelectric thin film and an electrode thereon, so that the one leg including the piezoelectric thin film and electrode, is made equal in width to the other leg.Hence, the both side tuning fork legs equal in width become equal in the resonance frequency and avoids leakage of vibration energy, whereby this piezoelectric vibrator is free from characteristic variation and has a high accuracy.

摘要： A code NCO is provided which correctly outputs a predetermined code enable signal by executing a simple control, depending on a frequency of a clock signal, with an optimal circuit scale. A multiplexer 1 receives integers of N and M which are relatively prime, and outputs either of them to an adder 2, depending on an output signal of a comparator 6. The adder 2 adds an integer latched by the register 5 and an integer output by the multiplexer 1, and outputs the result via a multiplexer 4 to the register 5. The register 5 latches and outputs the received integer to the comparator 6 with a frequency fs of a sampling clock signal SCLK. In accordance with a threshold set based on the integers of N and M and the number L of bits of the adder 2 or the register 5, the comparator 6 outputs a signal having the High state only when the output integer of the register 5 satisfies the threshold condition. The code NCO outputs this signal as a code enable signal having a frequency fo.

摘要： A calculus crushing apparatus includes a flexible sheath for insertion into a body cavity and an operation wire slidably inserted in the sheath. A basket for holding a calculus is fixed to the distal end of the operation wire. The basket is formed of a plurality of elastic wires. A connecting rod is connected to the proximal end of the operation wire. By moving the connecting rod by an operation mechanism, the operation wire slides in the sheath, so that the basket is projected from or retracted in the sheath. The connecting rod has a disconnecting portion which is weaker than the elastic wires and operation wire against tension.
