Patent number: 7993455Abstract: A polycrystalline silicon production apparatus is provided whereby when deposited silicon is caused to drip down into an underlying collection part by heating the reaction tube inner surface at a temperature equal to or above the melting point of silicon, the silicon melt can be prevented from solidifying at a lower end portion of the reaction tube due to temperature lowering at the lower end portion. When a reaction tube is heated with a high frequency heating coil, the temperature lowering at a lower end portion of the reaction tube is prevented through temperature lowering prevention means which may be an infrared device capable of heating the outer periphery of the lower end portion by means of infrared rays, or which may be a lower end coil that is constituted by a coil near the lower end of the high frequency heating coil and has an increased heating intensity relative to an upper coil.Type: GrantFiled: August 17, 2004Date of Patent: August 9, 2011Assignee: Tokuyama CorporationInventors: Junichirou Nakashima, Hiroyuki Oda

Publication number: 20100237124Abstract: A controller 50 has a single-driving mode/continuous-driving mode changeover switch 233 for performing fastener driving operation in a single driving mode or a continuous driving mode. In a case where the single-driving mode/continuous-driving mode changeover switch 233 instructs a single driving mode, the controller 50 causes a driver blade 3a to perform fastener driving operation when both a trigger switch 5 and a push lever switch 22 are switched, by switching operation, from the one switch status to the other switch status (e.g., the ON status). Consequently, fastener driving operation is made possible regardless of sequence of actuation of the trigger switch 5 and the push lever switch 22.Type: ApplicationFiled: September 14, 2007Publication date: September 23, 2010Inventors: Yukihiro Shima, Masahiro Inaniwa, Hiroyuki Oda, Takashi Ueda, Yoshihiro Nakano

Publication number: 20100163202Abstract: A press felt 10 comprises a base body 30, a wet paper web side batt layer 20, and a press side batt layer 23. The wet paper web side batt layer 20 has a wet paper web contact side batt layer 21 and a base body side batt layer 22, the wet paper web contact side batt layer 21 being made of a core-in-sheath fiber 41 which has a core member made of high-molecular-weight nylon with an absolute viscosity of 80 mPa·s or more and a sheath member made of nylon with a lower melting point than the core member, and the base body side batt layer 22 being made of a nylon fiber 42 which does not include the core-in-sheath fiber 41. Rewetting of the wet paper web can be prevented, because water within the press side batt layer 23 is blocked from moving to the wet paper web side due to increased density of the wet paper web contact side batt layer 21 resulted from melting of the sheath member of the core-in-sheath fiber 41.Type: ApplicationFiled: January 31, 2007Publication date: July 1, 2010Applicant: Ichikawa Co., Ltd.Inventors: Akira Onikubo, Shin Kawashima, Hiroyuki Oda
