摘要： To restrain temperature rise by controlling heat radiation from an IC. More specifically, an area of junctioning pads which are in contact with an IC is enlarged to substantially overlap the whole or at least half or more of the area of the IC. Further, the IC is covered with an overcoat which protrudes to other parts of a head supporting mechanism.

摘要： In the magnetic disk unit comprising suspensions in each of which an IC is mounted on a load beam, a magnetic head displacement caused by the warp of the load beam occurring due to heat generated from the IC is compensated, whereby the shortening of an access speed and high reliability of reading/writing are realized. The thermal displacement of the magnetic head is compensated by operating micro actuators on the load beam in accordance with the temperature rise of the IC which is measured by a temperature sensor. Namely, by driving the micro actuators so that the magnetic head may move in a direction reverse to the direction of the magnetic head movement caused by the thermal displacement, the thermal displacement of the magnetic head is made to be substantially zero.

摘要： Return channels 45a, 45b, 45c, and 50 are formed to guide air flowing through a clearance between a magnetic disk (11) and a shroud (41) so that the air flows behind a voice coil motor, bypasses a loading/unloading mechanism (31) and flows toward a region on the lower side of the loading/unloading mechanism 31 with respect to the rotating direction of the magnetic disk (11). Thus, production of turbulent flow in the vicinity of the loading/unloading mechanism 31 is controlled. Fluttering of the magnetic disk (11) can be controlled by placing a filter 60 in one of the return channels.

摘要： The magnetic head assembly including a magnetic head having a terminal composed of a conductive film and a supporting spring. The supporting spring has interconnecting patterns (lines) on the top thereof and a projective electrode. The terminal of the magnetic head is electrically connected to the projective electrode of the supporting spring by a solderless, direct contact connection. The magnetic head is fixed to the supporting spring by using a non-electrical bonding agent. This structure makes it possible to stabilize the position of the magnetic head assembly and the relative speed variation between the magnetic head element and the magnetic disk, thereby enhancing the reliability of the magnetic disk apparatus.

摘要： The plastic lens of the present invention consists of a copolymer obtained by copolymerizing a monomer mixture consisting of given proportions of diethylene glycol bis(allyl carbonate), benzyl methacrylate, diallyl phthalate (these three monomers has been used as a monomer mixture for conventional plastic lenses) and, as an additional monomer, an alkyl methacrylate. This copolymer has excellent adhesion to upper and lower molds and, when immersed in, for example, a cleaning solution such as a methylene chloride-strong alkali mixed cleaning solution or the like, causes no separation from the molds; accordingly in the copolymer, there can be prevented the occurrence of surface roughening, cloudiness and striae which have been problems in conventional plastic lenses.

摘要： A printer includes improved paper feeding mechanism. A manual paper guide plate below an automatic paper feeding device can guide a thick piece of paper into a printing position on the platen without bending it hard around the platen. A pin tractor below the manual paper guide plate can feed a continuous web substantially straight into the printing position. A print head below the platen prints out on the lower surface of printing paper, whereby the printed individual cut sheets of paper being piled up one after another with the printed surface facing downward in a proper page order. A paper tray for holding the printed paper can alternatively change its position to reverse the discharge direction of the printed continuous web. The printed and reversed paper can be stacked on the upper surface of the manual paper guide plate.
