Title: Antenna switching circuit
Inventor: SUZUKI HIROSHI
IPC: H04B1/38
Filed: 1994-12-19
Abstract: PURPOSE: To arbitrarily switch antennas by allowing a high frequency signal switching means to switch the route of a high frequency signal to a first antenna or an external antenna connection means by electric control. CONSTITUTION: When a control signal is inputted to an electric control switch 11, this switch 11 is switched to the side of a connector 2a for external antenna from the state shown in the figure to form the route of the high frequency signal between a high frequency circuit 4 and the connector 2a for external antenna. When the control signal is broken, the switch 11 is switched back to the state shown in the figure. Since switching of the switch is not dependent upon attachment/detachment of the plug of the external antenna by this constitution differently from the conventional technique, mutual positions of the connector 2a for external antenna and the electric control switch 11 can be freely set, and switching between an incorporated antenna 3 and the connector 2a for external antenna can be freely selected by the control signal.

Abstract: PURPOSE:To continuously and stably form films by composing an evaporating material crucible of plural conductive vessels formed with recessed parts and an insulating body holding these vessels and bringing an anode into contact selectively with only the specific vessel. CONSTITUTION:The evaporating material crucible is composed of the plural conductive vessels (10a, 10c, etc.) formed with the recessed parts and the insulating body 10z holding these vessels. The anode 2 comes into contact with the vessel 10a when the prescribed vessel 10a is positioned above a magnet 12 for plasma covergence by a rotating means 3. The vessel 10a is then conducted and only this vessel 10a selectively attains the same potential as the potential of the anode 2. Vapor deposition is executed from the vessel 10a. Even if the insulating film is formed on the surface of the evaporating material after the film formation, the plasma is concentrated only to the vessel 10a and the irradiation therewith is executed in the case of next execution of the vapor deposition from the same vessel 10a and, therefore, the insulating film is naturally removed and the safe and continuous film formation is executed. A mask 4 provided with a notch is preferably disposed above the crucible so as not to cover only the part above the magnet 12.
