A mold is provided in which a molding portion, formed between joint surfaces of upper and lower molds superimposed one upon the other, is filled with UV curable resin after arranging a coating formation portion of an optical fiber in the molding portion, the coating formation portion is coated with the UV curable resin when the resin is cured by irradiating light thereto from outside, and a shading plate is arranged in the periphery of the molding portion. In a case equipped with the mold, there is provided a mirror or a lens for reflecting UV light to UV curable resin.
摘要:
An impact tool for reducing noise without lowering the tightening ability. The impact tool gives a rotary blow force to a tip tool by mounting a rotary blow mechanism on a spindle rotatably driven by a motor and intermittently transferring the rotary blow force generated by the rotary blow mechanism from a hammer to the tip tool via an anvil, damping materials absorbing at least the vibration in the radial direction are arranged on at least one side of both supports of the axial direction of the spindle 7. The damping material is interposed between a bearing that rotatably supports the rear end portion of the spindle and an inner cover that holds the same, and an O-ring is interposed as a damping material between the front end portion of the spindle and an anvil that rotatably supports the same.

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.
摘要:
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.
