    摘要: The present invention aims to realize, in regard to a high frequency switch used for a mobile communication apparatus such as a portable telephone or the like, a dual band switch having simple structure and changeable to ON and OFF states in two bands. For realizing the aim, the present invention provide a dual band switch comprising a series circuit of a PIN diode (101) and its compensation circuit (102), and, the compensation circuit (102) is formed with a circuit having at least two series resonance points and one parallel resonance point. The above structure allows the impedance of the compensation circuit, which is capacitive in low frequency close to a direct current, to be inductive after undergoing the first series resonance point, whereby the parasitic capacity of the diode is canceled in the first band, and also to be inductive again after undergoing the parallel resonance point and the following series resonance point, whereby the parasitic capacity of the PIN diode is canceled in the second band.

    摘要: A laminated filter comprising a plurality of resonator electrodes, an inter-resonator coupling capacitor electrode for coupling adjacent resonators, and two input/output coupling capacitor electrodes for coupling input/output terminals and the resonator electrodes. This provides a capacitor electrode for electrically connecting one side of the input/output terminals with a portion of the input/output coupling capacitor electrode, wherein the input/output coupling capacitor electrode and the capacitor electrode are a parallel circuit. This structure forms a parallel resonance circuit in the input/output terminal, to provide an additional attenuation pole besides an attenuation pole formed by electromagnetic coupling between the resonators and an inter-resonator capacitance, thereby realizing a laminated filter of a high attenuation. With this structure, a duplexer can be made using a plurality of the filters of this invention without requiring a phase-shifting circuit.

    摘要: A can end is seamed to a cylindrical can filled with contents. The can is fed along a substantially elliptical path including straight and arcuate paths. While the can is being fed along the straight path, the can end is seamed to the can by a linear seaming device. At the same time, the can end is rotated by a can end holder which has a pinion gear held in mesh with a rack which extends fully along the elliptical path. The rack is composed of separate rack members which are relatively movable to adjust the tension of an endless chain that moves can ends and cans along the elliptical path.

A can end holder member is provided for detachably holding the can end directly above the can feed device and holding the can end rotatably about its own axis. A can end feed member is provided for moving the can end holder member to feed the can end in synchronism with the can which is fed by the can feed device. A lifting/lowering member is provided for lowering the can end holder member to hold the can end held by the can end holder member against an open end of the can. A seaming device is provided and extends linearly along the travel path for pressing an end hook of the can end against a flange of the can while the can end against which the can end is held is being fed by the can feed device. The can end holder member and the can feed device are rotated to roll the can end and the can along the seaming device to seam the can end to the can while the end hook of the can end and the flange of the can are being pressed by the seaming device.
