Abstract: PROBLEM TO BE SOLVED: To keep clean a ventilation device to be attached or detached without troubles by supporting the lower end of a filter frame by a holding claw of a support retained at a step of the lower end of the front wall and eliminating a groove where dust is apt to collect. SOLUTION: Protrusions 22a, 23a, 23b are formed along the longitudinal direction of an upper wall 22 and a lower wall 23 to form a filter frame 20 of a filter 30 made of an aluminum profile separately from a device body 10. A housing groove 11b is formed at the upper part of the front wall 11 of the device body and a step (c) and a fixing rib 11d are formed at the lower part. First, a plurality of supports 40 are inserted in slits of a vent hole 11a and a fixing recess 42b is fitted to the fixing rib 11d and a holding claw 43 is supported by the step 11c to attach the filter frame. Subsequently, the filter frame 20 is slightly tilted and the protrusion 22a is inserted in the housing groove 11b and then, it is lowered and the protrusion 23b is housed in the housing groove 43a of the holding claw 43 to attach the filiter frame. When detaching it, the reverse procedure is carried out.  The device body 10 has no groove where dust easily collects and the support 40 is a small-sized shape and hence, it can be easily cleaned and also kept clean and further, it can be attached or detached without troubles.

Abstract: PURPOSE:To confine ions in a silicon oxide film and a silicon oxynitride film in a short time by a method wherein a silicon electrode or a silicon oxide nitride electrode is dipped into a non-aqueous solution containing an electrolyte as an electrode and a voltage is applied. CONSTITUTION:A silicon electrode 1 and an opposed electrode 2 are dipped into a 1M acetonitrile solution 4 containing lithium perchlorate, for example, in a cell 6, a saturated calomel electrode 3 is dipped into a 1M acetonitrile solution 4 containing lithium perchlorate in a cell 7 and the cells 6 and 7 are coupled with each other using a liquid junction 5. Then, the potential of the electrode 1 is scanned using a potentiostat 8 and when the shift of a flat band potential is observed by a measurement of an impedance-potential using an impedance analyzer 9 for verifying a confinement of ions, it is known that the flat band potential is shifted on the side of a positive potential. Thereby, it is known that lithium ions are confined in a silicon oxide film which is formed by the reaction of water existing at a trace amount in the acetonitrile solution to the electrode 1.

Title: Energy-beam irradiation position measuring device and laser vapor deposition device using this device
Inventor: TANAKA HITOSHI
IPC: C23C14/28
Filed: 1989-12-08
Abstract: PURPOSE:To uniformize the thickness of a vapor-deposited film on a substrate with precision by photographing the light emitting part of a material to be irradiated melted by irradiation with an energy beam with an image pickup means in the tangential direction and allowing the body to be irradiated to get close to the substrate by the distance corresponding to the consumption of the body. CONSTITUTION:A body 7 to be irradiated rotating in a vacuum chamber 5 is irradiated with a laser beam 1 and melted, the vaporized particles are emitted from the body 7 in its normal direction and deposited on a substrate 8, and a film is formed. At this time, an ionized gas resulting from light emission is almost vertically generated on the surface of the body 7 to form a bloom 12, and the position of the bloom 12 is slowly changed as the body 7 is consumed. The position of the bloom 12 is photographed by an ITV camera 13 in the tangential direction to detect the position of the molten body 7, the body 7 is moved by a driving means 11 through a control means 14, and the laser irradiation position is held at an appropriate position with precision. As a result, the vapor deposition rate is fixed, and the thickness of the vapor-deposited film on the substrate 8 is uniformized.

Inventor: ONO TAKESHI
IPC: G03G15/02
Filed: 1988-12-20
Abstract: PURPOSE:To prevent a fact that the inside of a machine is stained and the picture quality is deteriorated due to a toner and paper powder by eliminating a toner and paper powder stuck to a corotron wire, and thereafter, sucking the surface of a part opposed to the corotron of a photosensitive member by a suction nozzle. CONSTITUTION:By operating a cleaning device in the course of warming-up of an electrophotographic copying machine, a toner and paper powder stuck to the corotron wire of an electrification corotron 10 are removed. Thereafter, a photosensitive member 1 is rotated at lower speed than the speed of the time of a regular cycle and a part B opposed to the corotron 10 is positioned so as to be opposed to a suction nozzle 72. That is, the toner and the paper powder which drop down onto a photosensitive member 2 are opposed to the suction nozzle 72. Subsequently, by driving a suction mechanism 73 by large power, the suction force becomes larger than that of an ordinary time, and the toner and the paper powder are sucked by the suction nozzle 72. In such a manner, it does not occur that the inside of a machine is stained and the picture quality is deteriorated due to the toner and the paper powder.

Title: Preparation of fluororesin film-coated steel sheet
Inventor: MORI KOJI
IPC: B32B15/082
Filed: 1995-11-14
Abstract: PROBLEM TO BE SOLVED: To improve resistance to food scorch by cooling the surface of a film at a specified temp. or below when a steel sheet after a fluororesin film is sticked thereon is heated again at a specified temp. or higher. SOLUTION: After a primer consisting of a mixed resin of a fuoroplastic and a heat-resistant resin is applied on the surface of a steel sheet and it is baked, the steel sheet is preheated and a tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer film is contact bonded and laminated thereon. Then, this is heated again while the surface of the film is cooled with a gas at 300 deg.C or lower so as to make the temp. of the steel sheet at least 380 deg.C. In this case, if the steel temp. does not reach 380 deg.C, enough heat-resistant adhesive properties are not obtd. In addition, when the temp. of the gas for cooling exceeds 300 deg.C, oxidation of the film surface is not sufficiently suppressed and heat-resistant non-pressure sensitive adhesive properties is decreased. It is possible thereby to improve resistance to food scorch.

IPC: B41J2/01
Filed: 1990-11-22
Abstract: PURPOSE:To prevent that a white or black line is recognized by the eye of a human being by forming the dot diameter due to the first nozzle in a line feed direction so as to make the same larger than the dot diameter due to the succeeding nozzle at every line feed. CONSTITUTION:Only the diameter D1 of the first nozzle 27a in a line feed direction among nozzles 27 is made larger than the diameter D of the other nozzles 27 to make the amount of the ink injected from the first nozzle 27a larger than that of the ink injected from each of the other nozzles 27. When the ink is injected to paper 20, for example, the diameter of the dot d1 of the first nozzle 27a is set to 140mum and the diameter of the dot (d) of each of the other nozzles 27 is set to 100mum. Therefore, the dot d1 due to the first nozzle 27a and the dod d2 due to the second nozzle 27 overlap by 20mum each other. By this method, it can be prevented that the black line due to the overlap of dots or the white line due to the opening between dots is recognized without increasing cost.
