Disclosed is a magnetic recording and reproducing apparatus of the rotating head type in which a magnetic tape is drawn out from a tape cassette by means of tape lead-out pins and brought into close contact with a head cylinder containing rotating heads. Each of the tape lead-out pins is mounted on a slide member which is adapted to be driven by a drive means and slideably guided along a guide path consisting of a guide slot formed in a base plate of the apparatus. With such arrangement, the guide path need not coincide with the path of the driving means, whereby the tape loading mechanism and hence the apparatus as a whole can be small in size.

Disclosed is a magnetic tape recording and reproducing apparatus or video tape recorder apparatus in which a magnetic tape is drawn out from a tape cassette by means of tape lead-out pins and brought into close contact with a head cylinder containing rotating heads. Each of the tape lead-out pins is mounted on a movable base having an engaging member which is adapted to bear against a first stopper for defining a limit of the tape lead-out movement of the movable base in the horizontal direction, while the movements of the movable base in the vertical direction are limited by a second stopper and lateral movements of the base are restricted by a third stopper, whereby the movable bases each having a tape lead-out pin are positively constrained at predetermined positions after the tape has been drawn out from the tape cassette.

A firing setter, which is useful for a heat treatment or firing step upon production of ceramic-based electronic device components or production of metal-based components obtained by injection molding, is provided with plural trough-holes and has an alumina content of at least 70 wt. %. Each of the through-holes is linear with substantially the same inner diameter along a length thereof and has an inner diameter of from 0.3 to 1 mm. A process for producing the firing setter is also disclosed.

A hybrid recording and/or reproducing apparatus can deal with a readout failure of all or part of AV information on a hard disk by restoring the record by using a backup record which has been saved on a tape, and also can expand the recording capacity as the whole system based on the combination of the hard disk and tape. The apparatus consists of a server which records and reproduces AV information on the hard disk, a tape unit which records and reproduces AV information on the tape, and a control system which controls to save all or part of the AV information to be recorded on the hard disk onto the tape simultaneously to or on expiration of a certain time after the recording of the AV information on the hard disk.

Disclosed herein is a case sealing structure and an assembling method therefor which can realize the dustproof and waterproof performances of the case with a simple configuration and reliability. The case sealing structure includes an upper case having a top portion and a side portion to define a lower opening; a lower case having a bottom portion and a side portion to define an upper opening, the lower case being engaged with the upper case with the lower opening and the upper opening facing each other; and an elastic sealing member having a top portion and a side portion, the sealing member being stored in the upper and lower cases. The inner surface of the side portion of the sealing member is formed with a groove engaging with the outer periphery of a printed board. The sealing member is held between the outer periphery of the printed board engaging with the groove and the inner surface of the side portion of the upper case.

A document processing apparatus includes a developing unit for developing a dot pattern, a recording unit for recording a dot pattern on a recording medium using an ink, a transfer unit for transferring the dot pattern developed by the developing unit to the recording unit, and a transfer control unit for controlling a transfer timing rate of the transfer unit to improve a fixing property of the ink to the recording medium recorded by the recording unit. The transfer timing rate is controlled in accordance with the time required to produce the dot pattern, in accordance with the type of dot pattern to be printed, or with the type of recording medium used.

摘要:
A hollow, blow-molded, bottle-shaped container of a biaxially oriented polyethylene terephthalate which has a stepped portion formed on the inner peripheral surface of a boundary between a neck portion and a shoulder portion with a body portion, and crystallized by a heat treatment before being biaxially oriented blow-molded from an injection-molded primary piece or parison, thereby abruptly reducing the thickness of the wall at the boundary from the neck portion to the shoulder portion to substantially equal the thickness of the body portion. This bottle-shaped container is manufactured from an injection-molded preformed piece or parison in which a recess groove is formed on the peripheral surface of the shoulder forming portion. Thus, any deterioration in the physical properties of the neck and shoulder portions of the bottle-shaped container can be eliminated.
