There is provided a position detecting apparatus that has a high ability of detecting a correct position even if there is mechanical play in a moving mechanical member, a position of which is detected, and an image processing apparatus provided with the position detecting apparatus. In a position detecting apparatus 100 of the invention, even if there is a certain degree of play in a slide plate 11 that moves in a slide direction DN and reading by bit mark reading sensors 21 to 24 deviates from regular reading of binary numbers, since binary numbers appended to a surface of the slide plate is formed by gray codes, a position derived by a position deriving unit is more likely to be controlled to be as small as adjacent binary numbers with respect to a slide direction of the slide plate compared with the case of the conventional simple binary numbers.

A method of efficiently creating an animation image data file is provided. Components of a device are modeled using a 3-D CAD system and filed. After file format conversion, the file is imported to application software for animation. The components are then assembled, a camera angle is selected, and the transparency of the components is specified. A video file is created and included in an HTML file which is a completed animation data file. A clear perspective of the device comprising complicated components can be obtained because some components created with 3-D CAD system are rendered transparent using the application software for animation.

A recording material separating apparatus has a rotary member contacting with a recording material, a separating member for contacting with the rotary member and separating the recording material from the rotary member, and a guide member for guiding that surface of the recording material separated from the rotary member which is adjacent to the rotary member. The guide member is provided for retraction from a guide position by the pressure of the recording material when jammed, and the separating member is retracted from a separating position in operative association with the retracting action of the guide member.

A sheet conveying apparatus and an image forming apparatus include a transfer roller which transfers a developer developing an electrostatic latent image on a photosensitive drum to a sheet, a pair of registration rollers which nip the sheet into a conveying nip formed by a pair of rotary members and conveys the sheet to the transfer roller, and an upper transfer guide for leading the sheet from the pair of registration rollers to the transfer roller. In addition, a conveyance regulating member regulates a conveying direction of the sheet conveyed by the pair of registration rollers and brings the sheet into contact with the upper transfer guide.

This invention relates to a resupplying apparatus detachably attached to an image forming apparatus body which comprise a resupplying passage connecting a sheet material passage on a downstream side of an image forming means in the image forming apparatus body with another sheet material passage on an upstream side of the image forming means. Also, the resupplying apparatus comprises switchback conveying means placed in the resupplying passage for reversing the conveyance direction of the sheet material upon reception of the sheet material from a conveyer in the image forming apparatus body, said switchback conveying means at least partially assembled in the image forming apparatus body; and resupplying means for returning the sheet material to the upstream side of the image forming means through the resupplying passage.

A foam molded product of a synthetic resin having a continuous hardened surface layer formed uniformly on a part or the whole of its surface during its foam-in-place molding and having a desired thickness. A mold and a process which can make such a product without bringing about any substantial change in an ordinary foam-molding operation. A part of foamable resin particles which are fed into the mold for making the product are caused to contact a mold surface heated to or above the melting point of the particles and melt to form a molten resin layer, and the molten resin layer is hardened to form the hardened surface layer.

A method is disclosed for controlling a simulated moving bed system of a type including at least four series-arranged beds each packed with a solid adsorbent, with the downstream end of each bed and the upstream end of the next succeeding bed being connected by conduits to form an endless loop, and in which a fluid is caused to circulate through the beds in one direction, a feed stock and a desorbent are introduced into the system while a raffinate and a sorbate are withdrawn from the system, and the positions of introduction and withdrawal of the four kinds of fluid are periodically shifted in the direction of the circulating fluid flow. In accordance with the invention, two or more circulating pumps, provided with variable speed controllers and pressure detectors for detecting the suction pressure of each of the circulating pumps, are disposed between two beds. The flow rates of three of the four fluids introduced into or withdrawn from the system are adjusted to predetermined values, and the flow rate of the other fluid is controlled in such a manner that the suction pressure of one of the circulating pumps or the average of the suction pressures of two or more of the circulating pumps is held constant, and a rotational speed of each of the circulating pumps is controlled independently so as to control the flow rate of the circulating fluid and to maintain the suction pressure of each circulating pump at a low level.

A series-connected, skin-current heating pipe circuit includes a first ferromagnetic pipe; a first insulated wire extending along and inside the first pipe; a first AC source connected to one end of each of the first pipe and first wire; and an impedance element, such as a resistor, capacitor or reactor connected between the other end of each of first pipe and first wire. A current trouble detector is provided in either line connecting the first AC source to the one end of the first pipe or the one end of the first insulated wire to detect a current trouble due to an insulation problem at any point of the first insulated wire. The circuit may include a second AC source, a second ferromagnetic pipe and a second insulated wire extending along and through the second pipe arranged so that the one end of the first ferromagnetic pipe is connected via the second ferromagnetic pipe, second insulated wire and second AC source to the first AC source and a current trouble detector is connected between a line connecting the first and second ferromagnetic pipes and a wire connecting the first and second AC sources to detect a current flowing therein. An impedance element in the form of a resistor, capacitor or reactor may be connected in circuit between the second ferromagnetic pipe and the second insulated wire.
摘要:
The present invention relates to a process for preparing a polyolefin foam by heat-molding pre-expanded beads of an expandable polyolefin resin containing a foaming agent in a mold, said process being improved in preparing beads having a peak expansion rate at pre-expansion equal to 1.3 to 3 times the expansion rate of beads to be packed into the mold, adjusting the beads to a pre-expansion rate depending on an expansion rate of the desired foam, and packing and molding the pre-expanded beads in a mold without any further addition of expandability thereto. The polyolefin foam prepared by the process of the present invention is evenly fused to the interior and is less liable to shrink or deform.
