IPC: G02B6/12
Filed: 1997-09-26
Abstract: PROBLEM TO BE SOLVED: To make it possible to inexpensively provide a semiconductor polarization control element which is free of optical coupling loss and is variable in wavelength by electrical control by periodically arranging diffraction grating elements having asymmetry in a direction perpendicular to a waveguide direction of light and a direction parallel with a semiconductor substrate into an optical waveguide, thereby constituting a polarization mode converter. SOLUTION: The polarization mode converter is constituted by periodically arranging the diffraction grating elements 1 having the asymmetry in the direction perpendicular to the waveguide direction of light and the direction parallel with the semiconductor substrate 2 in the optical waveguide 1 of the optical semiconductor device. The conversion of the polarized wave of the propagation light is made possible by using such asymmetrical waveguide structure. The constitution of the polarization control function of high efficiency is made possible by imparting periodicity to the structure in such a manner that the conversion process thereof interferes constructively, i.e., by periodically arranging the diffraction grating elements 6 of a length L having the asymmetry.  As a result, the semiconductor polarization control element which is free of the optical coupling loss and is variable in the wavelength by the electrical control is inexpensively obtd.

Abstract: PURPOSE:To produce spike for athletic sports easily and at a low cost without a partial lowering of intensity on the process by a method wherein organic binder is added to cermet sintering raw powder, and they are heated and kneaded, and injection molded into the shape of spike, and the obtained molded body is degreased and sintered. CONSTITUTION:As for cermet sintering raw powder, cermet powder may be used, or powder of oxide, carbide, or nitride of groups IVa, Va, VIa of the periodic system elements and metal powder of Co, Ni, Mo, etc., may be used. Thermoplastic organic material such as paraffin, etc. is added to cermet sintering raw powder as organic binder, which is heated and kneaded at higher temperature than a plasticizing temperature of organic binder to give it fluidity, then injection molded into the shape of spike. The molded body contains organic binder, so it needs a degreasing process in which it is heated at a given temperature to dissolve and eliminate organic binder before sintering. The degreased molded body is sintered to be spike on the ordinary cermet sintering condition. Therefore, pin part gets no streaks by a shaving process as usual, so that it is not subjected to a partial lowering of strength.

Title: Automatic boxing system
Inventor: TAKAHASHI MASARU
IPC: B65B5/10
Filed: 1992-09-30
Abstract: PURPOSE:To automatically fill folding carton by providing a regularly ordered counting and feeding device with a conveyor on its lower frame and a vertically movable force lever located at the side of this conveyor. CONSTITUTION:A folding carton G is moved from a belt conveyor part to a lower belt 12 of a regularly ordered counting and feeding device 3 and is carried through a transfer passage 10. At this time, by the detection of a residence sensor S1, the folding carton G is drawn in through a suction opening 29 and transferred on a receiving belt 20. When the folding carton G is held excessively long in the transfer passage 10, a control device activates a force lever 17 to move upward, and then the folding carton G on the lower belt 12 is lifted by the force lever 17 to move away from the lower belt 12, thereby blocking the path of the folding carton G toward an outlet part. This prevents the exertion of a great pressing force on the folding carton at a carrying-in opening part and consequent simultaneous feeding of the two folding cartons to the regularly ordered receiving device.

Title: Method for manufacturing semiconductor device and apparatus for manufacturing the semiconductor device
Inventor: SAKAI MASANORI
IPC: H01L21/205
Filed: 1999-09-16
Abstract: PROBLEM TO BE SOLVED: To form an HTO film having a uniform thickness an a whole. SOLUTION: An HTO film is formed on a wafer 4 by using a 2-leaf CVD apparatus 1. A uniformizing plate 60, which has a large surface area part 62 on its part facing the wafer 4, is placed in parallel with a retaining plate 50 which retains the wafer 4. If raw gas is made to flow through a process tube 2, film-forming seeds are deposited not only on the wafer 4 but also on the large surface area part 62. As the film-forming seeds deposited in excess on the center part of the wafer are consumed by the deposition of the film forming seeds on the large surface area part, the tendency where the thickness of the film on the circumferential part of the wafer is larger than that on the center part is suppressed, so that the thickness of the HTO film formed on the wafer is uniformized relatively as a whole.
