摘要:
The invention provides a resin-sealing apparatus that is operated with a low pressure and with a low clamping force without void generation and that is favorable for shortening the molding time and reduction of sealing resin consumption. In the resin-sealing apparatus of the present invention, a resin injection inlet of a pot has an opening at the center of the cavity surface of a cavity of a bottom mold that is a component of a mold unit, and a plunger for injecting molten resin in the pot from the opposite side to the resin injection inlet side is provided slidably and airtightly with the inside wall of the pot.
摘要:
A recording and/or reproducing apparatus and a magnetic disk cassette having a flexible magnetic disk and a cover for containing the magnetic disk. The cover has a driving hole for driving the flexible magnetic disk from outside of the cover, a recording opening for exposing a recording surface of the flexible magnetic disk, and a cut-out portion provided on one side of the cover for detecting correct installation of the flexible magnetic disk cassette into a recording and/or reproducing apparatus. A shutter is slidably provided on the cover for selectively exposing the recording surface through the recording opening and the cut-out portion when the flexible magnetic disk is ready for use. The recording and/or reproducing apparatus for the flexible magnetic disk cassette includes a driving member engaged with the flexible magnetic disk through the driving hole of the cover for rotating the flexible magnetic disk. A transducing head is contacted with the recording surface of the flexible magnetic disk through the recording opening when the shutter is in an operative position. A projection is provided in the apparatus in facing relation to the cut-out portion of the cover when the flexible magnetic disk cassette is installed correctly.
