摘要:
An image forming apparatus of the present invention includes a latent image forming device for forming a latent image on an image carrier and a developing device for developing the latent image with toner to thereby form a corresponding toner image. The surface of an intermediate image transfer body is movable and includes an high-resistance layer having a volume resistivity of 1010 &OHgr;·cm or above. A primary image transferring device transfers the toner image from the image carrier to the intermediate image transfer body. Secondary image transferring device transfers the toner image from the intermediate image transfer body to a sheet. A polarization uniforming device uniforms, at the beginning of an image forming operation, polarization left in the high-resistance layer while preserving the polarity of the polarization after the surface of the intermediate image transfer body has started moving, but before the toner image is transferred from the image carrier to the secondary image transfer body.

The invention provides a method of fabricating a thermoelectric device, whereby a grooved block composed of n-type thermoelectric semiconductor and a grooved block composed of p-type thermoelectric semiconductor, provided with a plurality of grooves formed therein, respectively, at a same pitch and parallel with each other, are formed such that a depthwise portion of respective grooved blocks is left intact, and then, an integrated block is formed by fitting and adhering together the grooved blocks composed of the n-type and p-type thermoelectric semiconductors, respectively, filling up gaps in fitting parts with adhesive insulation members. After removing portions of the integrated block, other than the fitting parts where the n-type and p-type thermoelectric semiconductors are fitted to each other, n-type and p-type thermoelectric semiconductor pieces are exposed, and by forming electrodes for connecting the pieces to each other alternately and in series, the thermoelectric device is completed.

A drill jig for a spectacle lens forms a closed-end hole in an edged face of the spectacle lens which extends inside the lens, a manufacture jig thereof, a method of drilling a spectacle lens, and a spectacle lens. The drill jig is composed of a jig body and a plurality of support members attached to the jig body. The spectacle lens is inserted and tightly retained in an opening of the jig body and supported by a plurality of the support members. A drill of a drill press, on which the drill jig is set, touches the edged face of the spectacle lens while being guided by a guide portion to thereby form the closed-end hole in the edged face.

The invention provides a method of fabricating a thermoelectric device, whereby a grooved block (11) composed of n-type thermoelectric semiconductor and a grooved block (21) composed of p-type thermoelectric semiconductor, provided with a plurality of grooves (16, 26) formed therein, respectively, at a same pitch and parallel with each other, are formed such that a depthwise portion of respective grooved blocks is left intact, and then, an integrated block (3) is formed by fitting and adhering together the grooved blocks (11, 21) composed of the n-type and p-type thermoelectric semiconductors, respectively, filling up gaps in fitting parts with adhesive insulation members. After removing portions of the integrated block (3), other than the fitting parts where the n-type and p-type thermoelectric semiconductors are fitted to each other, n-type and p-type thermoelectric semiconductor pieces are exposed, and by forming electrodes for connecting the pieces to each other alternately and in series, the thermoelectric device is completed. Further, it is preferable to apply a process of exposing the thermoelectric semiconductor pieces and a process of forming the electrodes after applying a process of forming grooves to the integrated block (3) such that a plurality of grooves are formed in the direction crossing the direction in which the grooves (16, 26) have been formed, leaving a depthwise portion of the integrated block (3) intact, and insulation members filling up the grooves thus formed are solidified.

In a method for producing a molded gasket having a surface treated layer on one surface of a substrate and integrally formed with a gasket body constructed by a rubber-like elastic body on the other surface, a first step of integrally molding the gasket body on the substrate, a second step of temporarily placing the molded piece on a placement stand, and a third step of removing a burr portion from a production portion by punching the molded piece are sequentially executed. For preventing foreign material attachment, pollution and scratching, the first step integrally forms a projecting leg portion constructed by a rubber-like elastic body at a position corresponding to the burr portion in the molded piece, the second step brings the molded piece into contact with the placement stand by the leg portion, and the third step removes the leg portion as a part of the burr portion.

An image forming apparatus includes an apparatus body in which an image forming section that forms an image on a recording material and a drive mechanism that generates a rotational driving force are provided; a fixing section that transports the recording material while receiving the rotational driving force and fixes the image on the recording material, the fixing section being held by the apparatus body at two axial ends thereof; and a transmission mechanism that is provided at one of the two axial ends of the fixing section and is connected to the drive mechanism, the transmission mechanism transmitting the rotational driving force from the drive mechanism to the fixing section. When a pulling force is applied to a recording material that is present in the fixing section, the drive mechanism and the transmission mechanism are disconnected from each other.
