Abstract: A capillary tube for a solder ball connection device connects a first connection surface of a pad to a second connection surface of a pad with a solder ball. The first connection surface is formed at a slider held by a slider holder in a disk unit. The second connection surface is formed at an end of a lead wired to the slider holder. The capillary tube has a ball regulator with a substantially conic, hollow portion. The solder ball regulator has an opening at its top that opens to the tip of the hollow portion. The center axes of the hollow portion and the opening are common. The solder ball regulator also has a pair of projections along the center axis around the opening, where the projections face each other with the center axis therebetween. The projections regulate the movement of the solder ball. The tip of the hollow portion is tapered when viewed from a line connecting the pair of projections and the extreme tips of the tapered tip portions.

Abstract: A head gimbal assembly, which is a component of a hard disk drive, has a bending portion that has elasticity and is bent at a predetermined angle under an unloaded condition, and a slider is bonded to a holding portion thereof by mounting the head gimbal assembly on a bonding jig in a state in which the bending portion is stretched. When the head gimbal assembly is separated from the bonding jig after bonding, the bending portion is not restored freely, so that the head gimbal assembly is caught by the bonding jig during the separating process and a locked state is sometimes established.

Abstract: In the corrugated metal sheet 5 in which the crest portions 5a and the trough portions 5b are formed in plural alternatively along the corrugation direction 61, the rack portions 5f, the rising trough portions 5d, and the rising crest portions 5e are provided in plural. The rack portions 5f are arranged between the crest portions 5a and the trough portions 5b and extended along the folding direction 60 and the corrugation direction 61 to couple adjacent crest portions 5a and trough portions 5b. The rising trough portions 5d are folded from the boundaries between the crest portions and the rack portions 5f such that part of the crest portions 5a being divided by two cuttings separated in the folding direction 60 are protruded partially in the same direction as the trough portions 5b.

Abstract: A head support arm of a disk drive device comprises; a front portion supporting a head/slider assembly, a rear portion pivotally mounted on a frame of the disk drive device, a bending portion between the front portion and the rear portion, a plurality of electrically conductive wires covered by a tube, and a first fixing position and a second fixing position symmetrically located on both sides of a center line of the head support arm at positions between the bending portion and the front portion, characterized in that the tube is attached to the head support arm between the bending portion and the rear portion, the plurality of electrically conductive wires extending from a front end of the tube on the side of the front portion of the head support arm extend over the bending portion and are divided into a first group and a second group, the first group of wires is fixed to the second fixing position.

Abstract: A multicellular transmission apparatus in a mobile communication network, capable of preventing delay involved in reassembling short packets into fixed length packets (ATM cells), degradation of communication signals due to the delay, and reduction of the transmission efficiency involved in assembling the short packets into the fixed length packets. When low speed information transmitted from a telephone set is converted into short packets by communication data assemblers/disassemblers in a mobile gateway switching center, followed by multiplexing of the short packets into the fixed length packets by fixed length packet assemblers/disassemblers, the short packets sent from a plurality of telephone sets are grouped for each destination node (a particular radio base station, for example) in the network, and are multiplexed into the fixed length packets belonging to the group bound for the destination of the short packets.

Abstract: The present invention provides a new tab structure for a head suspension assembly in a magnetic storage system. In the prior art method of assembly, a harness temporarily holds a wire assembly. The present invention eliminates the need for the harness, thereby reducing the number of parts and steps as well as improving productivity and quality. A flexure of a suspension assembly must be manufactured very precisely. The present invention provides a new tab structure either integral with or separate from the flexure. Wires bridge over to an extension on the tab structure at a predetermined distance from the end of the load beam. Positioning holes, using the extreme flatness of the tab structure, align the wires with the bonding pads of a head. The suspension assembly is subsequently bonded to the head, and the unwanted tab structure is removed to complete the head suspension assembly.

Abstract: An image formation apparatus is provided having a continuous form photosensitive member positioned to move along a pre-defined transfer path. An image is exposed on to a portion of the photosensitive member along the transfer path. A heat developer heats the exposed image portion and intercepts the heat to an unexposed portion of the photosensitive member. The heat developer has a cylindrical housing having a heated portion arranged along a longitudinal axis of the cylindrical housing and a heating element in surface contact with and for heating exposed portions of the photosensitive member. The cylindrical housing also has an unheated portion arranged along the longitudinal axis of the cylindrical housing and separated from the heated portion by a thermally insulative material.

Abstract: A method and an apparatus for liquid supply use a pressure tank and a plurality of pumps. When the pressure or liquid quantity in the pressure tank has decreased below a predetermined level, a preceding or regular pump starts. When the demand is too large for this pump, another pump in standby position starts, too. The regular pump continues running for a predetermined period of time after the start, even if the pressure or liquid quantity in the pressure tank has returned to a predetermined level, whereas the standby comes to a stop upon such recovery. In this manner the frequency of starting the pumps is minimized so as to avoid overheating of pump-driving motors and reduce the power consumption.

Abstract: A pellet casing is formed with concave louvers which cause volume reducing inward flexing of the casing when heated, and simultaneously provide low gas flow resistance therethrough.

Abstract: A pellet holding casing disposed in a container is formed at its wall sections with a plurality of louvers that extend outwardly away from the casing. Each of the louvers is formed with at least one channel shaped corrugation in substantially the top portion thereof for providing the converter with improved characteristics with respect to flow resistance and thermal expansion.
