IPC: H01L21/027
Filed: 1989-09-16
Abstract: PURPOSE:To obtain an orientation flat position and improve yield when producing a semiconductor integrated circuit without contacting the outer periphery of a water by measuring the position of a semiconductor outer periphery and that of a stage by using an image line sensor. CONSTITUTION:The position of outer periphery of a wafer 1 which is carried onto an orientation flat stage 3 is determined so that it may enter the visual field of an image linear sensor 24 (CCD). The rotary axis of the orientation flat stage 3 rotates at an equal interval by a stepping motor. The outer- periphery position signal of the wafer in CCD and pulse signal of the stepping motor are synchronized, thus enabling the orientation flat position to be detected roughly. Then, the orientation flat edge is introduced into the visual field of a visual field microscope for pre-alignment 2. The slope of the orientation flat edge within the visual field of the microscope is obtained by image processing on a TV monitor 21, a wafer is rotated slightly by a fine-move rotary table 5, thus performing fine adjustment of the orientation flat position and completing position detection thereof.

IPC: B41J2/44
Filed: 1984-11-14
Abstract: PURPOSE:To adjust the quantity of exposure without spoiling the reproducibility of half-tones of an original image by slanting the transmitted-light polarization direction of the 1st polarizer at 45 deg. to that of laser light from a light source, and allowing the 2nd polarizer to rotate freely around the optical axis. CONSTITUTION:A laser diode 1 generates light of light output proportional to the density of the original image and the polarization ratio of the parallel light of a collimator lens 2 varies with the light output; and the transmitted-light polarization direction of a beam splitter 3 slants at 45 deg. to that of the diode 1 and laser light having a constant polarization ratio is outputted regardless of variation in the polarization ratio of input laser light. Then, the quantity of transmitted light is adjusted by a splitter 5 according to its angle of rotation to vary the quantity of exposure to a film, and the degree of the variation is in linear proportion to the light output of the diode 1. The quantity of exposure is therefore adjusted without spoiling the reproducibility of half-tones of the original image.

Title: Elastic polishing roll
Inventor: KAYAHARA ISAO
IPC: B24D13/12
Filed: 1983-12-21
Abstract: PURPOSE:To allow abrasion machining, scale removal, and surface flaw elimination after the rugged face of the flat plate surface by spirally hooking and fixing the lower edge of the woven fablic portion of sector abrasion elements to a cylindrical drum at many places. CONSTITUTION:When a group of sector abrasion elements 1 spirally hooked and fixed by many steel wires 5 to the drum 9 of a grinding roll like a multi-thread screw are pressed to a metal plate, each grinding point follows the curved ruggedness of the metal plate due to the flexibility of the woven fabric portion 3 of the abrasion elements 1 and some left and right sway of the grinding elements 1, the grinding roll exerts the function as an elastic body and grinds the metal surface uniformly in the back and forth and the left and right directions. Since the grinding surface is formed by collecting point grinding due to the advance of the metal plate and the spiral displacement of contacts of the grinding elements 1, no vertical stripe is left on the plate surface.

Title: Method and device for desulfurizing gas containing hydrogen sulfide
Inventor: ROTAARU GEERIHI
IPC: B01D53/14
Filed: 1986-10-11
Abstract: The Takahax gas desulfurization method is rendered more energy-efficient and compact by providing separate scrubbing and regeneration loops operating from a common reservoir (31,33) and by using hyperbaric pressure in the oxygenating or regenerator vessel (59). The overall height of a plant of comparable capacity can be reduced from the 13 meters (about 40 feet) required by the prior art to 3.3 meters (10 feet) and can therefore be transported by truck. The preferred washing or scrubbing liquid is an alkaline solution using sodium 1,4 napthoquinone-2-sulfonate as the catalyst. By oxidation, elemental sulfur is made to precipitate and this is filtered out continuously in a filter (77). Regenerated washing liquid flows via a degassing vessel (69) into the common reservoir (27,31,33). In the degassing vessel, under relaxed pressure, degassing occurs, and the sulfur foam, along with the oxygen or air it contains, is returned via a pump (55) to the regenerator pressure vessel (59) or to the filter (77).
