    • An antenna device corresponds to a plurality of radio communications systems and frequency bands, can simultaneously carry out a reception and a transmission of different radio communications systems, and is capable of using antenna diversity by a simple construction. An antenna device comprises a first antenna matching with first, second, and third frequency bands, a second antenna matching with the third frequency band, a diplexer and the like. For signals of the first frequency band, a high-frequency switch circuit connects a transmitter or a receiver to the diplexer by switching. For signals of the second frequency band, an additional high-frequency switch connects a receiver or a transmitter to the diplexer by switching. For signals of the third frequency band, the additional high-frequency switch circuit and a further additional high-frequency switch circuit connect the second antenna or diplexer to a transmitter/receiver by switching.

    • In single crystal growth by means of a CZ method, a granular/lump polycrystalline raw material is additionally supplied into a raw material melt in a crucible through a vertical charging tube. A raw material accumulating section is provided at a site part way downward in the vertical charging tube working in such a way that a predetermined amount of the polycrystalline raw material is accumulated in the raw material accumulating section and the polycrystalline raw material in excess of the predetermined amount falls down. The polycrystalline raw material falling down in the vertical charging tube strikes against the accumulated raw material in the raw material accumulating section, thereby absorbing a shock of the falling raw material. The accumulated raw material works simultaneously as a protective member, thereby preventing breakage of the tube accompanying absorption of the shock from occurring. It is therefore possible to prevent melt splashing that is problematical when a lump raw material for recharge is charged using a vertical charging tube.

    • A method capable of securely pulling up a heavy single crystal is described. Using an apparatus comprising a crucible for storing a molten material for a single crystal; a heater for heating the molten material; means for pulling up the single crystal to grow by bringing a seed crystal in contact with the surface of the molten material in the crucible; and a flow-regulating member surrounding the single crystal at the growth area for shielding the heat of radiation and for regulating inert gas flow, the method comprises the following steps of setting the distance between the lower end of the flow-regulating member and the surface of the molten material to be a first distance D1 when the seed crystal comes into contact with the surface of the molten material in said crucible; forming the single crystal at the neck portion; thereafter setting the distance between the lower end of the flow-regulating member and the surface of the molten material to be a second distance D2 where D1 (mm)>D2 (mm); and forming the single crystal at the shoulder portion and subsequently forming the single crystal at the body portion. A dislocation-free single crystal having a heavy weight can be produced with a high crystal quality, and the method is applicable to various operation modes at which the apparatus is operated under various conditions of crystal growth.
