Abstract: Insulating ceramic parts for insulating collector electrodes in a traveling wave tube and a vacuum envelope are formed in a cylindrical shape in which the central axis of the inner diameter diverges from the central axis of the outer diameter and are constructed such that holes are provided in portions of the insulating ceramic parts where the thickness in the radial direction is great, and high-voltage leads for supplying prescribed voltages to said collector electrodes from the exterior pass through these holes.

Abstract: A vibration damping arrangement for a gondola of a type having a supporting unit attached to a cable, a hanger suspended from the supporting unit and a carriage suspended from the hanger. A vibration damping device includes an elongated hollow housing. A bottom plate of the housing defines a down-wardly arcuate oscillation track which extends in a direction perpendicular to the cable. A vibration damping body is movably located on the oscillation track such that it can naturally oscillate on the oscillation track in the longitudinal direction of the oscillation track upon vibrations of the carriage. The vibration damping device is located under a seat inside the carriage, suspended from a bottom of the carriage, supported by the hanger above a roof of the carriage or mounted on the roof of the carriage in such a manner that it does not extend beyond width and length of the carriage. The vibration damping device does not substantially occupy a passenger room so that comfortableness is not degraded.

Abstract: In a thermal-transfer-type color printer, an ink ribbon and a paper are sandwiched between a thermal head and a platen roller so that a specific image is transferred onto the paper in a specific color. The platen roller is made by a rubber material which has a certain degree of hardness. On the surface of the ink ribbon, plural colors of ink are sequentially and repeatedly painted. Hence, after transferring an image onto the paper in one color, the paper is moved backward; and then, another image is transferred onto the paper in another color. Thus, a multi-color printing is performed. In order to avoid a color shade or an printing error, in which a printing position of one-color image does not accurately match with a printing position of another-color image, the paper should be accurately moved forward and backward. In order to do so, the thermal-transfer-type color printer provides a precise paper-feed mechanism which comprises a pinch roller and a paper-feed roller.

Abstract: An image reader is capable of improving the quality of reading a transmission manuscript and of reducing a cost for a luminaire power source compared with the conventional image reader.

Abstract: A driving method for a gas discharge display panel especially of a large size. The invention uses a gentle rise-up waveform or stepwise rise-up waveform of the sustaining pulse to allow a more operational margin while not increasing load to the driving circuit.

Abstract: A work holding apparatus is a work holder for holding a work in a predetermined position in relation to a basic member. A base column is rotatably supported astride on two sets of base plates. Holding fixtures are removably mounted on each side of the base column, such that different types of works can be supported and clamped by the holding fixtures. An indexing-rotation driving device rotates the base column such that it may be applicable to various types of works, thereby facilitating the holding of many types of works and the replacement of supporters and clamps. Furthermore, the base plate for supporting the base column is divided into two sets to reduce the weight of the base plate moving parts, and a base plate synchronizing means is provided to insure synchronized operation of the two base plates.

Abstract: An electrophotographic recording apparatus comprising these units which are arranged vertically: a sheet feeder for feeding a sheet of recording paper to a sheet feed inlet; an image forming unit for forming a printing image onto a photosensitive drum based on printing data and transferring the printing image onto the sheet; and a fixing unit for fixing the transferred image on the sheet. The apparatus further comprises a sheet switching guide mechanism by which the head end of the sheet is switched to both upper and lower directions. When the sheet switching guide mechanism is set to the upper direction, the printed sheet is forwarded by a sheet guide member to thereby pass through the printing path the sheet has already been through with the rear side of the sheet being the front, and the printing data is written from the last line during this process.

Abstract: A paper feeding apparatus for a printer. There are at least two mounting members, each of which is adapted to contain sheets of paper. A paper feeding assembly is associated with each of the mounting members and contacts the paper in the mounting member for feeding single sheets of paper. A paper feed gear is operatively coupled to each of the paper feeding assemblies for co-rotation therewith. A sun gear is present proximate each of the paper feeding gears and each is rotatable about a center point. A transmission mechanism transmits rotational power in first and second directions from a paper feed motor in the printer to each of the sun gears. The first and second directions are opposite to one another. A selector member is associated with each of the paper feed assemblies and has a planet gear on a first arm and a protrusion on a second arm. The selector member is rotatable about the center point of the corresponding sun gear. The planet gear engages with the corresponding sun gear.
