Title: Paper feeder
Inventor: IWASAKI AKIHIRO
IPC: B65H1/04
Filed: 1991-01-28
Abstract: PURPOSE:To facilitate a paper supply from the front side as well as to aim at the promotion of space-saving by making the width of a front side fence smaller than that of a rear side fence, in a paper mounting part installed in one side of a body free of lifting motion. CONSTITUTION:At a paper mounting part 31, width size x1 of a front side fence 33 is set to be narrower than that x2 of a rear side fence 34. When paper 17 is supplied to this paper mounting part 31, a cover 35 is opened, many sheets of the paper 17 in pile are placed on the paper mounting part 31, extruding them in the arrow X direction, and one side part of the paper 17 is butted to a part of the rear side fence 32. Subsequently the paper 17 is thrust in space between the rear side fence 32 and the front side fence 33 in the arrow Y direction. At this time, the paper 17 is supported by the paper mounting part 31, so a burden to be imposed on an operator is reducible, and also, a working space of a body 1 at time of paper supplying can be shortened as far as a portion for shortening the front side fence 33, thus it is conducible to the promotion of space-saving.

Title: Surface acoustic wave device
Inventor: OKAMOTO TAKESHI
IPC: H03H3/08
Filed: 1981-02-27
Abstract: PURPOSE:To achieve easy manufacture by avoiding a crossing part, through the provision of electrodes so that a piezoelectric film provided on a substrate can be clipped. CONSTITUTION:A metallic electrode C is provided on a substrate 1 of a piezoelectric substance such as lithium niobate or nonpiezoelectric substance such as glass. A piezoelectric film 2 is laminated further on it. Metallic electrodes A and B are provided on the film 2.  Phase difference of 120 degrees is given among  the electrodes A,B, and C. The electrode fingers of the electrodes A, B and C  are alternately arranged in the interval of a wavelength lambda. As a result, unidirectional surface acoustic waves only are obtained, because the waves from each  electrode are synthesized to be strengthened for one surface acoustic wave and  the waves from each electrode are cancelled for another surface wave.

Title: Electronic typewriter
Inventor: KAWAKAMI KAZUO
IPC: B41J21/08
Filed: 1988-02-08
Abstract: PURPOSE:To reduce time and labor required for an operation, by printing data through inputting a printing-starting means corresponding to centering printing or left justification printing after the data is inputted, without setting the centering printing or the left justification printing. CONSTITUTION:Data is inputted from an input means 1, is stored in a data storage means 2, and is displayed on a display part 4. Based on centering printing or left justification printing determined by a selected printing-starting means 6, the data stored in the data storage part is processed by a printing-controlling part 3, and is printed by a printing means 5. When the inputted data is a return key signal, the centering printing is conducted to complete the process. When the inputted data is not the return key signal but is a tab key signal, the left justification printing is conducted to complete the process. When the inputted data is not the return key signal but is the tab key signal, the inputted data is stored in the storage means 2, and is processed in the same manner as above. At the time of forming a table, it is necessary only to input data and operate a printing-starting key, and it is unnecessary to preliminarily set or select a printing system, so that operating efficiency is enhanced.

Title: Mobile electrode type electric dust collector
Inventor: UCHIYA TSUNEO
IPC: B03C3/74
Filed: 1980-03-06
Abstract: PURPOSE:To obtain a mobile electrode type electric dust collector capable of effectively collecting high-resistance dust by fixing the center of both ends of a dust collecting electrode plate divided laterally in a rectangular form by means of an endless cable and moving the dust-collecting electrode plate in parallel to a discharge electrode by moving the endless cable. CONSTITUTION:A high voltage is applied between a discharge electrode 20 and a dust-collecting electrode plate 16 to form a dust-collecting region in a space where the discharge electrode 20 exists, where dust in gas is arrested at the surface of the electrode plate 16. Then, the dust-arrested electrode plate 16 is passed through the lower nondust collecting region where the discharge electrode 20 is not present and no gas is passed. And, dust adhered to the surface of the electrode plate 16 is scraped down by a dust remover 30 in the nondust collecting region in order to clean the surface of the electrode plate 16. Thus, since the electrode plate 16 is always cleaned and moved to the dust-collecting region, no reverseionization phenomenon occurs even when high-resistance dust is collected.

Filed: 1985-02-18
Abstract: PURPOSE:To prevent a track from producing an unrecorded portion or from recording dually even when its display is read and is concatenated by correcting the display by means of returning the counter dial in the reverse direction or advancing its dial in the forward direction so that a counter angle will be doubled integrally as many as a specified angle. CONSTITUTION:The counter angle of the counter dial 19 is read by mechanical means. In other words, pulses are fed to a stepping motor 38 one by one and make a counter fitting drum 89 and a bite pin 90 rotate counterclockwise step by step. When a state where a concave part 93 of the counter fitting drum 89 laps over a concave part 22 of the counter dial 19 and the bite pin 90 is raised to bite to the counter dial 19 is detected by a counter fitting detecting switch 94, pulse generations are suspended and a number of steps 'n' calculated so far (its number is the same as that of pulse) is regarded as the counter angles of counter dial 19. Thus if the step number which is read mechanically 'n' is not a partition number 'm'; that is an integral multiple of 20, the counter dial 19 is reverted or advanced.

Title: Method of reversing development
Inventor: GOTOU MASAHIRO
IPC: G03G13/09
Filed: 1983-02-23
Abstract: PURPOSE:To prevent fog and reduce consumption of magnetic toner, a carrier, by making volume resistance of magnetic particles less than 10<12>OMEGA and making relative moving speed of developer to an image carrier equal to or more than moving speed of the image carrier. CONSTITUTION:A photosensitive drum 2 moves in the direction of arrow (a), and a developing sleeve 15 rotates in the direction of arrow (b) at a peripheral speed faster than the photosensitive drum by about 20%. Magnetic toner having volume resistance of about 10<12>OMEGA is used. Dark part potential on the photosensitive drum is -600V, bright part potential is -150V, and voltage of DC -400V is impressed from a power source 8 to developing bias. Consequently, adhesion of magnetic toner, a carrier, to dark potential part, a non-picture part, is hardly recognized. As the quantity of adhesion of magnetic toner 13b increases in proportion to time of contact with the photosensitive drum 2, proper peripheral speed of the developing sleeve is about 100-140% of peripheral speed of the photosensitive drum. By this way, wasteful consumption of magnetic toner can be reduced, and fog of non-picture part can be prevented.
