    • 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.

    • 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.
