    摘要： A drill grinder for grinding a point of a drill including a shank, and a body which has the point. The drill grinder includes a holding device for removably holding the drill, and a grinding wheel adapted to be forced on the drill point, and to thereby grind the point while the drill is held by the holding device. The holding device includes a first chuck for gripping the shank of the drill, and a second chuck for gripping the body of the drill. The grinder has a holder mounting device for removably holding the holder device during a grinding operation on the drill by the grinding wheel. The grinder may further includes a drill setting device for removably accommodating the holding device, to position the drill in a predetermined circumferential position relative to the second chuck, prior to the grind operation.

    摘要： In a filter module, a common input/output portion of a switch circuit is set as a first port. A first filter arranged to pass a signal in a first frequency band is connected between a first input/output portion of the switch circuit and a second port. A second filter arranged to pass a signal in a second frequency band is connected between a second input/output portion and the second port. A phase adjusting circuit is provided such that an impedance in the second frequency band as seen from the first port while the switch circuit selects the first input/output portion is in a substantially short-circuited state. This arrangement prevents leakage of unwanted signals from a signal path used in a communication system not in operation among two communication systems for different frequency bands while the other communication system is engaged in communication.

    摘要： A high-frequency module includes a switching circuit having a phase-shift circuit. The phase-shift circuit matches only PCS/DCS reception signals so as to be passed therethrough by setting a control-voltage input terminal to a Low level when receiving PCS/DCS signals, and attenuates PCS/DCS transmission signals to the PCS/DCS reception circuit side by setting the control-voltage input terminal to a Hi level when transmitting PCS/DCS signals. Also, another phase-shift circuit, which further attenuates the PCS transmission signal when transmitting the PCS signal, is provided in the DCS Rx terminal side of the phase-shift circuit.

    摘要： A high-frequency composite component for selectively switching a GSM-system signal path and a DCS-system signal path for a signal transmitted to or received from an antenna terminal by a diplexer. Transmission-side input terminals and reception-side balanced output terminals to be switched by high-frequency switches are included in the GSM and the DCS systems. Matching elements include inductors and capacitors that are inserted between the reception-side balanced output terminals and the output side of surface acoustic wave filters.
