Patent number: 6846468Abstract: The invention relates to a method for decomposing bromate ions contained in a liquid. The method includes the sequential steps of bringing the liquid into contact with a photocatalyst; and irradiating the photocatalyst with a light ray having an energy that is not lower than that of a band gap of the photocatalyst, thereby generating a photocatalytic reaction to decompose the bromate ions. The invention further relates an apparatus for decomposing bromate ions contained in a liquid. The apparatus includes a first section for generating therein a photocatalytic reaction to decompose the bromate ions; a photocatalyst adapted to be brought into contact with the liquid in the first section; and a light source for irradiating the photocatalyst with the light ray such that the photocatalytic reaction is generated in the first section when the photocatalyst is in contact with the liquid. Thus, it is possible to efficiently and stably decompose the bromate ions.Type: GrantFiled: February 27, 2002Date of Patent: January 25, 2005Assignee: Kabushiki Kaisha MeidenshaInventors: Hiroshi Noguchi, Rie Kagami, Shigeo Sato, Miyoko Kusumi

Patent number: 5582523Abstract: A connector inspecting apparatus includes (i) a connector receiving portion for holding a connector which is to be inspected and which has a terminal and (ii) an inspecting portion which has a detecting piece corresponding to the terminal, and which is arranged for inspecting the connector by moving the connector receiving portion and the inspecting portion toward/away from each other. At least one of the connector receiving portion and the inspecting portion is rotatably attached to a base. The other of the receiving portion and the inspecting portion is so guided as to be moved toward/away from the first. When either of the receiving or inspecting portions is rotated, such a rotational movement is converted into a sliding movement of the other portion. Accordingly, by rotating one of the portions, the connector can be inspected. This not only reduces the space required for installing the connector inspecting apparatus, but also facilitates the inspecting operation.Type: GrantFiled: March 6, 1995Date of Patent: December 10, 1996Assignee: Sumitomo Wiring Systems, Ltd.Inventors: Michimasa Noro, Takao Ito, Shigeo Sato

Patent number: 4720726Abstract: A shutter driving apparatus drives a programmed shutter with a stepping motor, by using a driving current pulse whose waveform has a leading half that gradually increases in amplitude and a trailing half having an amplitude smaller than the peak value of the pulse. At each rotary stage of the stepping motor, a smooth starting operation can be ensured without any adverse inertial effect at the start or end of rotation, the stepping motor being temporarily driven at low speed at the end of each pulse. In the case of an aperture priority exposure control using a programmed shutter, disadvantageous ripple motion of the shutter sectors is eliminated, thus enabling high precision exposure control.Type: GrantFiled: October 28, 1986Date of Patent: January 19, 1988Assignee: Fuji Photo Film Co., Ltd.Inventors: Shigeo Sato, Yutaka Yoshida

Patent number: 4400074Abstract: An automatic rewinding camera wherein an automatic advance of the photographic film by one frame is caused by shutter release operation and rewinding of the photographic film is automatically started when the film is prevented from further advance. The camera has a film-driven sprocket wheel, by the rotation of which film movement signals are produced. A timer circuit maintains, during the passage of a predetermined active time which is shorter than the time required to advance the photographic film by one frame, the camera motor in forward rotation so as to advance the photographic film. The timer circuit is reset by the film movement signals. But when those film signals stop, that is, when the film is fully extended from the cartridge, then the timer is not reset; and the measurement of the full predetermined active time, by the timer, without resetting, results in the motor being reversed to rewind the film.Type: GrantFiled: March 1, 1982Date of Patent: August 23, 1983Assignee: Fuji Photo Optical Co., Ltd.Inventors: Kazuhiko Akiyama, Takeshi Yoshino, Michihiro Shiina, Shigeo Sato, Tetsuo Nishizawa, Toshio Yoshida, Nobuo Kobayashi

Patent number: 4253476Abstract: A tobacco filter having a hollow cylindrical body which is preferably transparent, is provided with a plurality of small holes in its outer wall, and with a solid impermeable hit-stick coaxially positioned within the hollow body. A porous annular-shaped filter element surrounds the axial mid-part of the hit-stick. Impurities in tobacco smoke are removed by a process of hit-sticking extraction in the form of numerous black dots on the surface of the hit-stick as well as the result of automatic, rapid self-liquefication of the filter element. At one end of the hollow cylindrical body a filter tip is positioned to be held in the mouth of the smoker, and at the other end is a cigarette holding part for receiving and holding a conventional cigarette.Type: GrantFiled: July 31, 1978Date of Patent: March 3, 1981Inventor: Shigeo Sato
