Patent number: 5593334Abstract: A water walker for walking or skiing over the water. Each walker consists of multiple inflatable tubes attached to one another and with an opening in the middle for inserting the foot. The foot rests on a foot plate supported by a tubular structural support system running horizontally the length of the walker. Propulsion is accomplished by a plurality of pockets made of a flexible membrane joined to the underside of the walker and used either independently or in conjunction with water ski poles or sails. Tabs with grommets or other means are provided at the front, middle and rear for tethering the pair of water walkers together to create a raft. A removable fin may be positioned beneath the foot or at the rear, depending on whether the walkers are used with a sail, as water walkers or as water skiis. The entire apparatus is lightweight and may be transported in a special backpack.Type: GrantFiled: August 9, 1995Date of Patent: January 14, 1997Inventor: Thomas E. Thayer

Patent number: 5586038Abstract: Manufacturing history of a product is accumulated without burdening a host computer which manages a production line. Whenever a work or part to be assembled is fed to the production line, a management terminal sets an operation data area corresponding to the work in an operation file. An operation terminal is provided for each step in the production line. These operation terminals each identify a work arriving at a corresponding step station and detect the contents of operation to be carried out on the work. The detected operation contents are written in an operation data area corresponding to the identified work in an operation data area in the operation file.Type: GrantFiled: December 28, 1993Date of Patent: December 17, 1996Assignee: Honda Giken Kogyo Kabushiki KaishaInventor: Masao Nagaoka

Patent number: 5580658Abstract: A function ally gradient composite material containing copper and carbon as main components and having a predetermined shape, in which the composition ratio of the copper to the carbon in the material continuously varies in at least one predetermined direction. The material is manufactured, for example, by impregnating carbon felt with a resin and thermo-compressively molding the impregnated felt (step S101), carbonizing the resin by baking (step S102) to provide a preformed carbon material (step S104). Pyrolytic carbon is thereafter deposited in the preformed carbon material by the CVI method (step S105) to provide a carbon material having the bulk density varying in a predetermined direction (step S107). After the wettability of the carbon material against copper is improved by siliconization (step S108), pores of the carbon material are impregnated with copper (step S109) to obtain a functionally gradient composite material of copper and carbon.Type: GrantFiled: July 12, 1994Date of Patent: December 3, 1996Assignees: Doryokuro Kakunenryo Kaihatsu Jigyodan, Toyo Tanso Co., Ltd.Inventors: Tadashi Maruyama, Katuhide Nagaoka, Masaki Okada

Patent number: 5557985Abstract: An apparatus for coupling a cleat has a pedal shaft for rotatably supporting a pedal, a tread surface extending parallel to the pedal shaft for contacting a bottom of a shoe, a first pivotal axis provided on the pedal, and a first cleat clamp pivotable about the first pivotal axis. The first cleat clamp includes a recess for engaging one end of the cleat until a force exceeding a predetermined value is applied thereto. Further, this apparatus has a second cleat clamp opposed to the first cleat clamp across the pedal shaft, and a pair of restrictor projections disposed between the second cleat clamp and the pedal shaft for restricting displacement to the cleat. The second cleat clamp cooperates with the first cleat clamp to couple the cleat to the pedal. The restrictor projections are spaced apart from each other by a distance greater than a width along the pedal shaft of a portion of the cleat for contacting the restrictor projections.Type: GrantFiled: January 23, 1995Date of Patent: September 24, 1996Assignee: Shimano Inc.Inventor: Masashi Nagano

Patent number: 5555562Abstract: A flexible articular conditioning system includes a plurality of elongated, solid, non-shifting weight members. The weight members may be removable for cleaning, and may be replaced by progressively heavier weight sets. Weight is not merely added to the wearer. The weights are advantageously evenly distributed across the body and located above and below the respective joint cavities. The disclosed systems are particularly well suited for sports specific training. The articulates may be properly and safely conditioned while exercising the muscles that control those articulates.Type: GrantFiled: September 2, 1994Date of Patent: September 17, 1996Inventors: Steven J. Holt, Alan W. Holt
