Inventor: NAKANO HARUYUKI
IPC: G06T7/00
Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To substantially save recognition working time and a pellet mounting time by a method, wherein a scanning area of a superior pellet of a rectangular shape obtained by a first time image recognition is set as a scanning area in a wafer at a next time and after. SOLUTION: In a first time image recognition, with the same method as in the first time when a circle 15 having a prescribed and larger radius than a wafer 2 is set as a scanning area, and a structure is made by a superior pellet 1a without lacking of pellets, the entire wafer 2 is scanned. In the image recognition of the wafer 2 at a next time and after, with the same method as at the first time, the image recognition starts, and at the point of time when it is recognized that a certain column is a column B of a polygon by increasing the number of conforming item pellet 1a existing in the same column in the X-direction more than a last column, in scanning of the next column on, the area is all changed to the inside of an outer periphery of the superior pellet 1a obtained on the image recognition of the wafer 2 at the first time.  Furthermore, even in a method for recognizing a minute work piece such as a capacitor chip, etc., naturally the function is exhibited.

Title: Water content percentage measuring device for grain dryer
Inventor: KANEFUJI YUUJI
IPC: G01N27/04
Filed: 1979-07-19
Abstract: PURPOSE: To minimize an amount of grains which are crushed and wasted during a water content measuring operation therefor, by lightly press the grains in an initial stage of a drying operation therefor to roughly measure the percentage of water content thereof, and crushing the grains when the drying thereof has progressed, to minutely measure the percentage of water content of the grains.  
     CONSTITUTION: When the percentage of water content of grains is higher than a predetermined level in an initial stage of a drying operation therefor, the grains are lightly pressed between a front end surface of a rod electrode 17 and a receiving plate 22. An electric current is then applied to the grains to measure the percentage of water content thereof on the basis of an electric resistance of the grains. When the drying of the grains has progressed with the percentage of water content measured in the mentioned manner of the grains has become lower than a predetermined initial standard level, the rod electrode 17 further advances, so that the grains are crushed between the front end surface of the rod electrode 17 and receiving plate 22. At this time, the percentage of water content of grains is measured precisely.

Title: Rotary polygon mirror
IPC: G02B26/10
Filed: 1992-03-18
Abstract: PURPOSE:To reduce wind whistle at the time of when the rotary polygon mirror is rotated at a high speed, and to prevent each mirror face from being contaminated. CONSTITUTION:The rotary polygon mirror 1 has the rotary reflecting surface 1A consisting of mirror surfaces 1a-1f being parallel to its rotary shaft, and also, being adjacent to each other, and between each mirror surface 1a-1f, chamfering is performed by a small inclined surface 1O. Each small inclined surface 1O is formed so that an angle made by the mirror surface being toward the front in the rotational direction becomes small by making chamfered width A of the mirror surface being toward the front in the rotational direction of the rotary polygon mirror 1 larger than chamfered width B of the mirror surface being toward the rear thereof, by which air resistance at the time when the rotary polygon mirror 1 is rotated is reduced.

Title: Manufacture of semiconductor device
Inventor: NAKADA TAKAAKI
IPC: H01L27/00
Filed: 1984-05-09
Abstract: PURPOSE:To improve the high-frequency characteristics, by forming an insulation film on a single-crystal substrate and forming a field effect transistor on this insulation film. CONSTITUTION:An insulation layer 10 is formed on a single-crystal substrate 9 and provided with apertures by the ordinary photoetching process. An N type polycrystalline silicon layer 11 is formed over the whole surface thereof by the vapor growth and then modified to be a single crystal layer 12 by laser annealing or electron beam annealing. A field effect transistor is formed in the single- crystallized region over the insulation layer 10. Since such field effect transistor is separated from the Si substrate 9 by the insulation layer 10, the capacity between them is very small, and therefore it has better high-frequency characteristics than other field effect transistors having a conventional construction when their gate oxide films have the same gate length, the same gate width and the same thickness.

Title: Production of sodium silicate
Inventor: KASHIWASE HIROYUKI
IPC: C01B39/52
Filed: 1982-06-01
Abstract: PURPOSE:To produce sodium silicate in high operation efficiency, by using the waste liquid containing caustic soda and discharged from a synthetic zeolite preparation process as the liquid for dissolving cullet, thereby effectively utilizing the waste liquid and achieving high filterability of the sodium silicate solution. CONSTITUTION:In the production of an aqueous solution of sodium silicate by the hydrothermal treatment of sodium silicate cullet, an NaOH-containing waste liquid composed mainly of the washing liquid discharged from the preparation process of synthetic zeolite is used as the water for dissolving the cullet or as an agent for adjusting the composition of the dissolved sodium silicate solution. A large amount of the NaOH-containing waste liquid discharged from synthetic zeolite plants can be utilized without using the expensive and complicated treatments such as acid neutralization and filtration nor using expensive concentration and purification processes for the recovery. The water for dissolving sodium silicate glass can be saved, and the caustic soda in the waste liquid can be completely utilized. Furthermore, the presence of the Al2O3 and residual zeolite in the waste liquid as a filter aid enables the easy filtration of the sodium silicate solution.

Title: Superconducting wiring
Inventor: TAWARA SHUICHI
IPC: H01L39/06
Filed: 1990-04-09
Abstract: PURPOSE:To increase the critical current density, and return the normal conduction part generated in a current-applied superconducting wiring to the superconducting state without cutting off the current, by dividing a wiring part constituted of superconducting material formed on a substrate into fine lines having a width narrower than the effective magnetic field permeation length. CONSTITUTION:In a superconducting wiring 1 constituted of superconducting material formed on a substrate 2, said wiring 1 is divided into thin lines having a width 3 narrower than the effective magnetic field permeation length of the superconducting material. For example, one wiring line is divided into thin lines whose width 3 is W satisfying the relation of W<lambda<2>/t where lambda is the magnetic field permeation length of the superconductor and (t) is the film thickness 4 of the superconductor. Thereby the permeation of magnetic flux quantum into the superconductor can be prevented and the critical current density can be increased. Hence the resistance of a normal conduction transition part is restrained to be small, and the Joule's heat generated in said part can be restricted within the cooling capability of refrigerant, and therefore, when a part of the superconducting wiring is transferred in the normal conduction state, said part can be returned to the superconducting state without cutting out the applied current.
