Title: Growth device for crystal
Inventor: OOTA TAKAO
IPC: H01L21/208
Filed: 1982-03-30
Abstract: PURPOSE:To grow a single crystal having a desired diameter satisfactorily in a growth device for a crystal, by a pulling method by irradiating a laser ray to the melt near the inside wall of a crucible. CONSTITUTION:Polycrystalline Si is packed in a crucible 1 and is heated to an Si melt 11 by a heater 2. Thereafter, the degree of heating with the heater 2 is regulated to drop the temp. of the melt 11 down to the temp. adequate for seeding. A laser ray is generated from a YAG laser light source 8 or the like and is passed through an optical fiber 9 so as to be irradiated to the melt 11 near the inside wall of the crucible 1 through an introducing port 10 for the laser ray. In parallel with the irradiation, the seed crystal 12 at the forward end of a crystal pulling shaft 5 is immersed in the melt and is pulled gradually. Since the shaft 5 and a shaft 3 for supporting the crucible are turned in mutually opposite directions by driving mechanisms 6 and 4 respectively, the melt 11 is irradiated and heated uniformly, and the crystallization of the melt near the inside wall of the crucible is suppressed effectively.

Title: Method and device for preventing surging in centrifugal compressor
Inventor: OHASHI SHIGENOBU
IPC: F04D29/44
Filed: 1988-03-08
Abstract: PURPOSE:To provide a device for preventing surging which can restrain increase of shaft motive force by partially recirculating pressure fluid on a discharge side to an intake side while performing bypassing when respective stages come lose to surging conditions at every stage. CONSTITUTION:A bypass member 15 is provided at every centrifugal compression unit stage. When only a centrifugal compressor unit coming close to or having reached surging is allowed to perform surge recirculation, it is possible to prevent surging. As for stages which are not close to the conditions, therefore, it is not allowed to perform bypassing and the bypassing is performed at the same time, in prior arts. On the contrary, according to this inversion, it is possible to obtain similar surging effects with remarkably small amount of bypass flow. It is thus possible to reduce the bypass flow and to cover a broad operation area while restraining the increase of shaft motive force.

Filed: 1984-03-19
Abstract: PURPOSE:To enable to prevent frictional load in feeding a paper from being increased, even when using a thicker paper, by a construction wherein a plurality of paper guides are provided so that the curvature of a printing paper differs depending on each of the guides, and a guide extension part is provided on the inlet side of the lower one of the guides. CONSTITUTION:Other than a paper guide 16 for ordinary papers which is provided at an upper part, a paper guide 20 for thick papers is provided at a lower part so that the curvature of the printing paper in feeding the paper differs depending on each of the guides (the curvature is smaller for the guide 20). Accordingly, when using a thick paper, the paper is passed through the lower guide 20 to a position between a feeding roller 14 and pinch rollers 14B, whereby it is possible to prevent the pressure and frictional forces exerted on the paper being passed from being increased and to prevent unsatisfactory actions, residual curl or the like from being generated. In addition, since the guide extension part is detachably provided on the inlet side of the guide 20, a thick paper can be easily inserted. Further, since a rear part of the printer is supported by bulking when fitting it, the curvature can be made sufficiently small, without increasing the size of the printer itself.

Title: Fluorite refractive index measuring method, florite selecting method and fluorite
Inventor: SAKUMA SHIGERU
IPC: G01N21/41
Filed: 1998-03-05
Abstract: PROBLEM TO BE SOLVED: To enable measurement of the index of refraction of a fluorite without directly measuring the index by measuring the content ratio of lead in the fluorite. SOLUTION: Though high accuracy is required for measuring the index of refraction of color abberation correcting optical material, the index of refraction of material fluorite scatters and thus measurement of the index is essential. The refraction index of a fluorite can be measured by measuring the content ratio of lead in the fluorite. In the measurement range up to about 5,000 ppm of the content ratio, the content ratio is substantially proportional to the index of refraction thereof. In the case that it is not more than 2,000 ppm, there is a rather linear line relation between the content ratio and an increase amount of the index of refraction thereof than another case, and in this measurement range the index of refraction thereof can be obtained easily from the lead content ratio.  If the lead content ratio is not more than a fixed value the index of refraction of fluolite is in an allowable range in designing, while with the exclusive selection of fluorite whose index of refraction is in the allowable range it is possible to prevent re-designing of an optical system for the fluorite whose index of refraction is out of the range. Accordingly, with the measurement of lead content ratio in fluorite, the index of refraction thereof can be obtained.
