CONSTITUTION:This control system is constituted of a projected image converter 1, a collision deciding means 2, a projected image conversion system determining device 3, and a collision evading direction determining device 4. An object moving in three-dimensional space is projected as an image on a plane vertical to its advancing direction, also an obstacle arranged in a three-dimensional space is projected as an image on the same plane, the speeds and positions of both the objects are detected and the future probability of collision between the moving object and the obstacle is decided in consideration of the practical size of the moving object. Consequently, the detection of the obstacle and the evasion of collision can be automatically executed.

Title: Manufacture of gaas solar cell
Inventor: HISAMOTO YOSHIAKI
IPC: H01L31/04
Filed: 1985-06-27
Abstract: PURPOSE:To improve the workability and yield by previously forming an insulating film over the peripheral portion of one principal surface to the sides of an N-type GaAs substrate before the liquid phase epitaxial growth. CONSTITUTION:After an N-type GaAs substrate 1 prior to the liquid phase epitaxial growth is boiled with trichlene, an insulating film 13 is deposited thereon in a normal-pressure CVD furnace. After a required photoresist mask is formed on the insulating film 13 by means of the photoengraving technique, etching is applied to the insulating film 13, leaving the insulating film 13 over the peripheral portion of one principal surface to the sides of the substrate 1. With this, the abnormal occurrence of a quenched layer in the peripheral portion can be prevented when a crystal is formed on the principal surface of the substrate by means of the liquid phase epitaxial growth, the substrate becomes easy of insertion into and taking-out from the substrate holder, and the occurrence of breaking of the substrate is reduced, thus improving the product yield.

Abstract: PURPOSE: To obtain a self-regenerable catalytic body by carrying a catalyst on an aluminum oxide coating film of a specified thickness formed on the front side of each of two substrates, laminating the resultant two catalytic bodies while holding a heating element between the rear sides and imparting a pipe or plate shape. CONSTITUTION: Aluminum is thermally sprayed on the front side of each of two stainless steel substrates to form an aluminum oxide coating film of about 30-300μm thickness and a catalyst is carried on the coating film. The resultant two catalytic bodies 2 are laminated while holding a heating element 4 capable of resistance heating between the rear sides and a pipe or plate shape is imparted to obtain the objective catalytic body. Since this catalytic body is self-regenerable, it can be used in a catalytic reaction liable to cause poisoning.

Filed: 1987-06-08
Abstract: PURPOSE:To accurately execute a relative alignment operation of a reticle with a wafer by using a light source for alignment use whose wavelength is different from the wavelength for exposure use. CONSTITUTION:An illuminating beam for exposure use from a light source device 10 as a light source for exposure use illuminates a reticle R uniformly by a first-wavelength beam lambda1; a desired pattern on the reticle R is then projected onto a face of a wafer W by a projection objective lens L. A second- wavelength beam lambda2 for alignment use which is fed from an He-Ne laser as a light source 1 for alignment use is converted into a desired beam diameter by using a beam expander composed of positive lenses 2, 3; the beam in a parallel beam state is reflected at a reflector 4 and is guided onto the reticle R. The parallel beam passes through a rectangular opening and proceeds to an incident pupil of the lens L. The parallel beam of the wavelength beam is converted on the wafer W by using the lens L and illuminates an alignment mark formed on the wafer W. By this setup, a relative alignment operation of the reticle R with the water W can be executed accurately.

Title: Snare wire for high frequency excision
Inventor: FUJIMORI TAKAHIRO
IPC: A61B18/14
Filed: 1988-06-09
Abstract: PURPOSE:To loading the excised part of a polyp, etc., to the internal surface of a loop with being averaged and adhered by forming a snare wire with shape- storing alloy. CONSTITUTION:A snare wire 3 is formed by the shape-storing alloy and stored so as to be bent in a loop shape at an almost same temperature as a temperature in a body cavity. For example, when the polyp is excised and the snare wire 3 is protruded from the tip of a tube 1 in the body cavity, the wire is bent in the loop shape by the temperature in the body cavity and a loop 3a is formed. Then, the excised part of the polyp can be caught by this loop 3a. Since a prescribed angle is obtained between an operating wire 2 and the loop 3a, which is formed by the snare wire 3, or the snare wire 3 is bent in a prescribed shape, the excised part can be loaded to the internal surface of the loop 3a with being averaged and adhered even when the polyp is in any position.

Title: Treatment of waste water
Inventor: HASHIMOTO NOBUKO
IPC: C02F1/58
Filed: 1988-06-09
Abstract: PURPOSE:To effectively remove fluorine even if a phosphoric acid compound is mixed by adding a water-soluble calcium compound to waste water containing a phosphate ion and a fluorine ion to form fluoroapatite and subsequently adding a ferric salt thereto to remove a precipitate. CONSTITUTION:A water-soluble calcium compound is added to waste water containing a phosphate ion and a fluorine ion to form fluoroapatite, and a ferric salt and a polymer flocculant are subsequently added thereto to remove a precipitate. Since the phosphate ion is not contained in the waste water after fluoroapatite is formed or the amount thereof is sufficiently reduced, the added ferric salt is formed into ferric hydroxide in neutral-alkaline waste water without being reduced to a ferrous ion to form flocs and these flocs are precipitated along with fluoroapatite. By this method, even when the phosphate ion is mixed, fluorine in waste water can be efficiently removed as compared with the other comparing example in a figure.

Title: Key information detecting circuit
Inventor: YAMAGISHI ATSUHIRO
IPC: H04M3/60
Filed: 1983-08-04
Abstract: PURPOSE:To attain miniaturization by constituting a key information detecting circuit in an attendant board of a communication exchange circuit network so that closing information is detected by a transistor (TR) and a diode activated from the operating command from the exchange and transmitting the information from a photocoupler. CONSTITUTION:When the attendant board operator operates a key SW, a corresponding TR is conducted by an expanded output of a decoder DEC by the operating command from a controller to conduct the diode D1. Since a reverse voltage is applied to a fiode D2 by it, the D2 is nonconductive, an OFF signal appears at the photocoupler PC to inform the controller that the key SW is closed. When no key SW is operated, although the TR is conductive by the operating command, the diode D1 accommodated in the board is nonconductive, the diode D2 is conducted and an ON signal appears at the photocoupler PC and the signal is fed to the controller.

Abstract: PURPOSE:To detect a target chemical substance, especially an offensive substance, with high sensitivity by fixing a thin film, obtained by causing polymer reaction under presence of a target chemical substance and extracting the target chemical substance from an organic polymer, to the surface of a transducer. CONSTITUTION:The biomimetic sensor 1a comprises a gold electrode 2 formed on the surface and rear of a crystal unit 1, a thin polymer (MIP) film 3 formed thereon while storing the three-dimensional molecular structure of the target chemical substance, and a lead 5 passing through a supporting base 4. At first, polymer reaction is methacrylic acid and ethylene glycol dimethyl acrylate is caused under presence of a target chemical substance, i.e., geosmin, to produce an MIP. The MIP can be utilized as a selective receptor having a molecule recognition function similar to the antibody of an organism. When a thin MIP film 3 is formed on the surface of the crystal unit 1, the unit 1 can serve as a sensor for detecting the target chemical substance with high sensitivity based on the variation in the frequency or resonance angle of light caused by the selective adsorption of molecule in the target chemical substance.
