Title: Production of silicon single crystal and production device therefor
Inventor: KAMIO HIROSHI
IPC: C30B29/06
Filed: 1989-06-02
Abstract: PURPOSE:To prevent clogging of raw material feed pipe in pulling up single crystal while feeding a raw material to a raw material supply part partitioned from a single crystal growth part in a crucible by making the raw material feed pipe quenchable with a gas. CONSTITUTION:A Si single crystal growth part at the inner side of a crucible in which molten Si is put is divided from a raw material supply part to supply Si raw material at the outside of the crucible by a partition member between both the parts. As the Si raw material is continuously fed to the raw material supply part and melted, the molten Si is gently transferred through a small hole of a partition member to a single crystal growth part to produce single crystal from the single crystal growth part. In this method, the Si raw material is continuously fed from a raw material feed pipe to the liquid level of melt of the raw material supply part. For example, a high melting metal or quartz pipe 2 is spirally laid along the raw material feed pipe 1, the raw material feed pipe is covered to the vicinity of an outlet part 3 of the feed pipe 1 and a gas such as Ar is introduced from one end C of the pipe 2. Consequently, the feed pipe 1 is indirectly cooled and adhesion of the Si raw material in the interior of the feed pipe can be prevented.

Patent JP-S5766535-A (JP)
Title: Focus detector
Inventor: KATOU KIICHI
IPC: G11B7/09
Filed: 1980-10-13
Abstract: PURPOSE:To detect an in-focus state efficiently and accurately all the time with regard to an optical reader for a video disk, by providing a prism, whose reflective surface is set at a critical angle, in a return optical path, by detecting its reflected luminous flux by two photodetecting elements, and by finding their output difference. CONSTITUTION:Return luminous flux from a disk 26 is made incident to a prism 28 through a condenser lens 27, and its reflected light is photodetected by a photodetector 30 having photodetection areas 30A and 30B. Since the reflective surface  28a of the prism 28 is set at a critical angle to the optical axis, light having an  angle of incidence greater than the critical angle is totally reflected and light having a less angle is transmitted partially, decreasing the luminous intensity of reflected light extremely. In this constitution, the photodetector 30 has no output difference in an in-focus state, but the photodetection areas 30A and 30B have a great difference in luminous intensity in an out-of-focus state according to the relation of the  angle of incidence, and the output difference is supplied to a differential amplifier  31 to obtain a focusing error signal. Thus, the in-focus state is detected accurately  at any time with the sufficient quantity of light over a wide area.
