Abstract:
The compact coin hopper for holding and dispensing coins in bulk includes a rotable disk for releasing individual coins to a sliding base beneath the rotable disk for ejection from the coin hopper. The upper surface of the rotable disk includes an upper step part and a lower step part connected by a riser part. The upper step part has a crescent arc shape with a radii smaller than the radius of the rotating disk in a planar view. One end of the crescent arc shape terminates adjacent an edge of the through hole while the other end of the crescent arc shape diverges away from the through hole and terminates adjacent a peripheral side edge of the lower step part. The configuration of the upper and lower step parts and the riser part assist in dispensing a coin.
Abstract:
One embodiment of the invention includes a preamplifier system for a magnetic disk-drive. The system includes a current distributor configured to generate a reference current and to decay the reference current from a first magnitude to a second magnitude during a degauss period to degauss a magnetic disk write head. The degauss period defines a transition from a write cycle to a read cycle of the magnetic disk-drive and has a predetermined time duration that is independent of the first magnitude of the reference current during the write cycle. An output driver is configured to provide a write current to the magnetic disk write head having a magnitude with an absolute value that is based on the reference current.

The present invention provides a current-sense bias circuit for use with a magnetoresistive head. In one embodiment, the current-sense bias circuit includes a voltage biasing portion configured to provide a bias voltage across the magnetoresistive head thereby establishing a bias current through the magnetoresistive head. Additionally, the current-sense bias circuit also includes a current sensing portion coupled to the voltage biasing portion and configured to sense a change in the bias current based on a resistivity change of the magnetoresistive head.

Abstract:
The present invention provides a column-and-beam join structure which absorbs energy caused by a large earthquake or the like by split tees surely yielding at a prescribed value, does not cause other members to fracture, and thus makes it possible to replace only the split tees which have become unusable, and, more specifically, a column-and-beam join structure constructed by attaching and connecting, using bolts 9, the ends 8a of both the upper and lower flanges 8 of a steel beam (H-shaped steel beam) 7 between the webs 6 of a pair of upper and lower split tees 4 the flanges 5 of which are connected to a steel column 1 using bolts 3. The upper limit of the yield stress of the steel material used for the split tees 4 is defined to be not more than twice the lower limit thereof. Further, in order for the web 6 extending from the flange 5 of a split tee 4 in the axial direction of an H-shaped steel beam 7 to absorb earthquake energy by its plasticization, the cross-sectional area of the web 6 is reduced partially and the base end portion 6a of the web 6 is divided from the tip portion 6b which is connected to the flange 8 of the H-shaped steel beam 7.
Abstract:
A vehicle-mounted record medium reproducing apparatus having a personal computer function. The apparatus is equipped with a control panel tiltable manually through a tilting link mechanism provided to cover a record medium insertion opening of a reproducing apparatus body. Further, the apparatus is provided with a click sensation mechanism for providing a click sensation when the control panel is tilted to a record medium ejecting position, and further provided with a connecting member for establishing a connection between the control panel and the supporting plate and being released from its connecting condition when the supporting plate is moved to a connection release enabling position. With this apparatus, a record medium can be inserted and ejected safely and with certainty, and the control panel can be detached from the supporting plate in a safe condition.

Abstract:
There is disclosed a vacuum-pressure regulating device which is attached to a vacumm system in connection with a vacuum pump so that it serves to ensure a constant vacuum pressure in the vacuum system and then to supply vacuum pressure from the vacuum system, after reduced to the required extent, to a desired space. The vacuum-pressure supply device of the present invention is suitable for adjusting vacuum in vacuum systems for milking cows. The vacuum-pressure supply device consists of such a structure that there are provided two independent but adjacent sections built of casings, one of them is partitioned by a diaphragm to form a first chamber and a second chamber, the other section is partitioned also by a diaphragm to form a third and a fourth chamber, a valve secured to each diaphragm is actuated according to a pressure difference between both sides of each diaphragm thereby automatically permitting air from the vacuum system or atmospheric air to flow into or flow out from each of the aforesaid chambers, thus maintaining two vacuum systems connected to the vacuum-pressure supply device as a desired high vacuum system and a desired low-pressure system respectively.
