Abstract: The present invention is to realize a magnetic recording and reproducing apparatus in which even if a spacing between shields of a magnetic head is narrowed, a deterioration in characteristic caused by a short-circuiting between a magnetoresistive layer and a magnetic shield layer is prevented to provide a high recording density. The present invention comprises an upper shield layer 15, a lower shield layer 13,and a magnetoresistive layer 14 arranged therebetween. Further, there is provided a constitution in which one or both shield layers has (have) a high resistance layer comprising a mixed layer of ferromagnetic metal and an insulating material, or a discontinuous multi-layer having a plurality of ferromagnetic metal layers and a plurality of insulating material layers laminated alternately, to prevent a deterioration in characteristic caused by a short-circuiting.

Abstract: The image formation apparatus according to the present invention has a document setting portion for setting a document, a size setting button for setting the size of a paper on which an image of the document is transferred by selecting it from a plurality of sizes, an automatic-operation key for instructing to automatically determine whether or not an orientation of the set document is the same as that of the image receipt body of a predetermined size, a detecting portion for detecting the orientation and size of the document set on the document setting portion on the instructions of automatic determination by the automatic-operation key, a determination portion for determining whether or not the orientations of the set document and the image receipt body are equal to each other, and whether the sizes of the set document and the image receipt body of a predetermined size are equal to each other, a display portion for displaying an operation procedure which should be performed by a user in accordance with the

Abstract: A method for producing a copolymerized polyester resin, which comprises subjecting a dicarboxylic acid component containing terephthalic acid or its ester derivative as the main component and a phenylene dioxydiacetic acid as a copolymerizable component, and a diol component containing ethylene glycol as the main component, to polycondensation through an esterification reaction or a transesterification reaction, wherein the phenylene dioxydiacetic acid is added to the reaction system in the form of a solution dissolved in the diol component.

Abstract: The toner cartridge of the present invention has an elongated cylindrical container containing toner and is set at a predetermined position such that the lengthwise axis of the container extends in the substantially horizontal direction. A supply port for dropping and supplying the toner in the container in the gravity direction toward the apparatus body. An auger extended immediately above the supply port in the substantially horizontal direction is provided in the container. The auger rotates thereby feeding the toner from inside the container toward the supply port along the rotary shaft. A plate-like regulation member for restricting drop of the toner in the container toward the supply port due to its dead weight is attached to a position opposed to the supply port above the auger.

Abstract: The present invention relates to a multilayer polyester sheet comprising:a base layer comprising a thermoplastic polyester resin (A) having a glass transition temperature of not less than 80.degree. C., anda sealing layer comprising a thermoplastic polyester resin (B) having a glass transition temperature at least 5.degree. C. lower than that of the base layer and laminated on at least one side of the base layer,said multilayer polyester sheet being a substantially non-stretched transparent sheet.

Abstract: In a television apparatus having a television receiver, a video tape recorder for recording and reproducing video and audio information included in a received television signal and being susceptible to distortion of the recorded video information when subjected to vibrations at substantially a predetermined mechanical resonant vibration frequency, speakers for audibly reproducing the audio information of the television signal, and a single cabinet containing the television receiver, the video tape recorder and the speakers so that the video tape recorder is influenced by vibrations generated in response to operation of the speakers; an audio signal processor which acts on the received and reproduced audio information to provide an audio output signal for driving the speakers includes a suppression circuit operative in at least the recording mode of the video tape recorder for relatively suppressing at least a component of the audio output signal having substantially the predetermined mechanical resonant vibra
