摘要:
An apparatus for positioning at least one magnetic head relative to a magnetic tape for recording and reproducing information includes a head unit for holding at least one magnetic head and a moving unit for moving the head unit parallel to a surface of the magnetic tape in a direction along the width of the magnetic tape so that the head unit is kept at a constant angle relative to the surface of the magnetic tape.

A magnetic writing/reading apparatus is provided with a holder which holds a cassette containing a magnetic tape, the cassette being inserted into the holder. A locking mechanism locks the cassette at a predetermined position in the holder when the cassette is to be loaded in the magnetic writing/reading apparatus, the locking mechanism being released when the cassette is to be ejected from the magnetic writing/reading apparatus. Also provided with is a carrying mechanism for carrying the holder holding the cassette so that the cassette is loaded in the magnetic writing/reading apparatus, the carrying mechanism which carries the holder holding the cassette causing the holder to be returned to a position at which the cassette has been initially inserted into the holder. Further, provided is a force generating mechanism for generating a force while the cassette is loaded in the magnetic writing/reading apparatus, the force generated then being applied to the cassette appropriately so that maintenance of the loading state of the cassette and a suitable writing/reading operation using the magnetic tape in the magnetic writing/reading apparatus are ensured.
摘要:
An air conditioning apparatus is provided which includes a plurality of heat exchangers (11, 12, 13) for effecting heat exchange between a heating medium (such as refrigerant, cold and hot water et cetera) and air and which is adapted to separately perform sensible heat processing and latent heat processing of room air (RA). In the air conditioning apparatus, at least one heat exchanger (13) is made up of an adsorption heat exchanger (13) that supports on its surface an adsorbent, thereby preventing the increase in apparatus size and making it possible to perform operations at high COP.

A humidity control system (10) includes a refrigerant circuit (50) including a compressor (53), a first adsorption heat exchanger (51) carrying an adsorbent thereon, an expansion valve (55) adjustable in opening and a second adsorption heat exchanger (52) carrying an adsorbent thereon, supplies humidity-controlled air to a room by operating alternately in a first batch mode in which the second adsorption heat exchanger (52) adsorbs moisture in air and the first adsorption heat exchanger (51) releases moisture to air and a second batch mode in which the first adsorption heat exchanger (51) adsorbs moisture in air and the second adsorption heat exchanger (52) releases moisture to air, and controls the opening of the expansion valve (55), when a valve control start time has come a predetermined time after the start of each batch mode, so that the degree of superheat of refrigerant in the refrigerant circuit (50) reaches a predetermined value.
摘要:
In a casing (11) of a humidity controller (10), a first heat exchanger chamber (37) which accommodates a first adsorption heat exchanger (51), and a second heat exchanger chamber (38) which accommodates a second adsorption heat exchanger (52) are arranged next to each other in the left-to-right direction. An indoor air side passage (32) and an outdoor air side passage (34) are provided on the rear panel portion (13) side of the heat exchanger chambers (37, 38), and a supply side passage (31) and exhaust side passage (33) are provided on the front panel portion (12) side of the heat exchanger chambers (37, 38). The rear panel portion (13) is provided with an outdoor air intake opening (24) and an indoor air intake opening (23) at locations close to a center of the rear panel portion (13) in the left-to-right direction. A first side panel portion (14) is provided with a supply opening (22) at a location close to the front, and a second side panel portion (15) is provided with an exhaust opening (21) at a location close to the front. A supply fan (26) is connected to the supply opening (22), and an exhaust fan (25) is connected to the exhaust opening (21). By this structure, a pressure loss at a time when air flows in the casing can be reduced.
摘要:
An optical disk drive includes a spindle motor for rotating an optical disk, and an optical pickup head. On a base plate, a pickup moving motor moves the optical pickup head in a disk radial direction. A motor plate supports the spindle motor. A spacer holder has a small thickness, and is secured to the base plate. A spacer boss is disposed to project from the spacer holder toward the motor plate. A first hole is formed through the spacer boss. A retaining screw has first and second shaft portions. A screw hole is formed in the base plate, for engagement with the first shaft portion inserted through the first hole, to retain the retaining screw. A great diameter peripheral surface is positioned at the second shaft portion, for applying pressure to fit the spacer boss tightly on the motor plate. Further, the spacer is formed from plastic material.
