    摘要： A recording medium detecting system includes a magnetic field-generating unit that generates an alternating magnetic field in a predetermined particular region, a detecting unit provided close to the particular region, that detects a change in magnetic flux density not smaller than a predetermined magnetic-flux-density difference B2, and a recording medium, containing multiple magnetic wires made of a magnetic material and formed in a wire shape having a predetermined length, that causes a large Barkhausen effect when the alternating magnetic field is applied. A magnetic-flux-density difference B1 detected by the detecting unit at an installation position thereof when the recording medium is placed in the particular region is not smaller than the magnetic-flux-density difference B2.

    摘要： A driving circuit for an acoustic printer and an acoustic printer which enables high speed and high image quality recording and is reduced in size and cost. An inductance switching circuit connected in parallel to an electrostatic capacity included in a piezoelectric element is connected to an amplifying part. The inductance switching circuit and the electrostatic capacity form a parallel resonance circuit called TANK circuit. The inductance switching circuit is formed by two inductances and switches connected in series to the respective inductances, and the inductances are connected in parallel. The switches are externally controllable.

    摘要： A cordless telephone consisting of base and handset units is disclosed wherein a control circuit incorporated in the base unit comprises first and second D/A converters, first and second A/D converters, and first and second sync. signal generation circuits. The first and second D/A converters respectively convert digital signals from the handset unit and a PBX. The first and second A/D converters convert the analog signals provided from the first and second D/A converters to transmit them to the PBX and handset unit, respectively. The first sync. signal generation circuit regenerates a first clock signal synchronously with a sync. signal provided from the PBX to render the first A/D and second D/A converters to operate in synchronism with the sync. signal from the PBX. The second sync. signal generation circuit generates a second clock signal which is independent of the sync. signal from the PBX to render the first D/A and second A/D converters to operate in synchronism with the second clock signal. Accordingly, the synchronization between the base and handset units is effected independently of the synchronization signal from the PBX.

    摘要： A tuning fork utilizing elastic coupling between the flexural mode and the torsional mode in which the frequency of the flexural mode is adjusted by adding or reducing masses deposited near the center of the arms in the lengthwise direction and the frequency of the torsional mode is adjusted by adding or reducing masses deposited on the other portions such as the tops of the arms. The positions near the center of the arms in the lengthwise direction are suitably selected so that adding or reducing the masses thereto or therefrom changes only the frequency of the flexural mode changes only and the frequency of the torsional mode is scarcely changed.
