Abstract: A flow control valve employing a step motor includes a valve housing having liquid inlet and outlet passageways, and a guide space which is communicated with the liquid inlet and outlet passageways, a spool which is connected to be movable up and down to the guide space of the valve housing so as to control an openness of the outlet passageway, a spool guide which is accommodated in an upper portion of the guide space so as to flow a refrigerant liquid downward by being moved together with the spool, an elastic support which elastically supports the spool guide in one direction, a seal member which is connected to a lower end portion of the valve housing, wrapping around a lower portion of the spool, so as to prevent a leakage of the refrigerant liquid, and a driving mechanism having a step motor to move the spool up and down, in which employing a dilatant liquid and a diaphram is eliminated and a proportional control is enabled, to thereby enhance the flow control performance and a durability of the valve.

Abstract: The present invention is related to a tray loading type magnetic recording and reproducing apparatus. The tray loading type magnetic recording and reproducing apparatus includes a deck mechanism for accommodating different size tape cassettes, a cassette housing covered and fixed at the upper surface of the deck mechanism, a cassette tray combined with the cassette housing in such a manner that the cassette tray can be rectilinearly moved back and forth and being capable of selectively accommodating different size tape cassettes, a tray loading device for loading the cassette tray and a cassette holder receiving device for receiving a previously received tape cassette in the cassette tray in a predetermined position of the deck mechanism. Thus, a new formed tray loading type magnetic recording and reproducing apparatus for accommodating different sized tape cassettes, capable of simplifying its formation, reducing fabricating cost and using in a home is provided.
