Patent number: 5768800Abstract: Apparatus for fluidizing a pulverulent material in a stream of fluidizing gas includes a membrane through which the fluidizing gas can flow but the pulverulent material cannot, a first fluidizing gas gallery on a first side of the membrane, a second fluidized pulverulent material gallery on a second side of the membrane, a passageway out of the second gallery for the removal of fluidized pulverulent material therefrom, and apparatus for generating a signal indicative of fluidizing gas pressure inside the second gallery and controlling fluidizing gas pressure in the second gallery in response to the generated signal. The passageway accommodates a conveyor having multiple conveying sections. At least a first of the multiple conveying sections is located adjacent an inlet opening of a housing for the conveyor. The first conveying section is generally coextensive with the inlet opening. A conveyor drive mechanism is selectively engageable with the conveyor.Type: GrantFiled: June 8, 1995Date of Patent: June 23, 1998Assignee: Matsuo Sangyo Co. Ltd.Inventors: Christopher R. Merritt, Anthony J. Smotherman, Michael J. Thies

Patent number: 5686725Abstract: A method for reading of information, which comprises printing information on a metal substrate or a substrate capable of transmitting infrared rays of 2-10 .mu.m wavelength, with a marking ink containing tin oxide, indium-tin mixed oxide or a mixture of tin oxide or indium-tin mixed oxide and at least one compound selected from the group consisting of alumina, barium sulfate, silicon dioxide and calcium carbonate, as necessary coating a clear coating or a coloring ink on at least the information-printed area of the substrate, and identifying the information by the use of a CCD camera sensitive to infrared rays of 2-10 .mu.m wavelength or an infrared detector. No noise is generated even when the reflectance of a light from the substrate surface is large, and the information can be identified (read) easily.Type: GrantFiled: June 6, 1995Date of Patent: November 11, 1997Assignees: Kansai Paint Co., Ltd., Fujikura Ltd., Matsuo Sangyo Co., Ltd.Inventors: Tsutomu Maruyama, Atsushi Akiyama, Hiroyasu Matsuki, Kazuo Sanada, Sadao Chigira, Masanobu Hidaka

Patent number: 5400976Abstract: A frictional electrification gun for use in electrostatic painting which can electrostatically charge power paint to a sufficient degree without the need of an elongated and twisted charging portion made up of nonconductive resin tubes. At the inlet of the charging portion made up of nonconductive resin tubes is provided a pre-charging portion for dispersing and charging powder paint. It has a nonconductive resin ring through which powder paint is fed swirling along its inner surface. The paint is thus sufficiently charged.Type: GrantFiled: June 1, 1994Date of Patent: March 28, 1995Assignee: Matsuo Sangyo Co., Ltd.Inventors: Haruhisa Kaijyu, Kenji Horita

Patent number: 5335828Abstract: A fluidized type paint powder tank has a fluidizing chamber for fluidizing paint powder and a storage chamber into which the paint powder in the fluidizing chamber is fed to keep it still. There is also provided a paint supply device for an electrostatic painting apparatus that includes a paint tank for containing paint powder and a painting gun coupled to the paint tank through an injector and a hose. The device includes a discharge member for discharging the paint powder from the paint tank and a hopper for receiving the paint powder discharged by the discharge member. A screw feeder is provided under the hopper. With this arrangement, the paint powder supplied at a uniform rate by the screw feeder is fed into the injector.Type: GrantFiled: February 5, 1993Date of Patent: August 9, 1994Assignee: Matsuo Sangyo Co., Ltd.Inventors: Haruhisa Kaiju, Hitoshi Yoshida, Junichi Yukikawa, Akihisa Yoshizaki

Patent number: 4958678Abstract: A method for producing a crystalline reinforced block material, wherein a crystalline material in molten state at a high temperature is laminated in thin film form on a base material. Heat is dissipated in the direction of the base material to rapidly cool the crystalline material. Simultaneously high pressure and large shearing force is applied to the crystalline material, as the material is cooled, by a pressing means to cool and solidify the crystalline material into a thin film form on the base material. Further laminates of the crystalline material in molten state at a high temperature are laminated in a thin film form on underlying thin layer surface in molten state or semisolidified state, one after the other on the immediately proceeding laminated thin layer.Type: GrantFiled: December 23, 1988Date of Patent: September 25, 1990Assignees: Yugenkaisha Idearesearch, Matsuo Sangyo Co., Ltd.Inventors: Yuzo Kawamura, Sigeo Nakagawa
