Abstract: In a vehicle seat, a central support member typically consisting of wire mesh or grid and supports most of the load of the vehicle occupant via spring members, and undergoes a relatively large displacement when the occupant is seated in the seat. Thus, by detecting the displacements of various parts of the central support member, preferably peripheral parts thereof, the magnitude of the total load and distribution of the load can be evaluated both reliably and accurately. Additionally, displacement sensors for measuring such large displacements are relatively inexpensive and easy to handle. Also, such sensors would not interfere with the existing seat designs, and would not be adversely affected by the equipment of the seat such as seat heaters.

Abstract: To reduce the manufacturing processes of a control rod and shorten the time required for manufacturing a control rod, for the lower part support member 7, the thin parts 11A and 11B are formed in the neighborhood of each of the left and right sides of the window 8. In the left and right sides of the pull-up handle 9, the grooves 17A and 17B are formed respectively. The groove 17B is deeper than the groove 17A. The thin part 11A is fitted into the groove 17A and the thin part 11B is fitted into the groove 17B. The gap formed between the end of the thin part 11B and the bottom of the groove 17B is larger than the gap formed between the end of the thin part 11A and the bottom of the groove 17A. Therefore, the thin part 11A can be simply fitted into the groove 17A.

An object of the present invention is to provide a manufacturing method of a control rod for a boiling water reactor, having excellent corrosion resistance in high temperature water and excellent wear resistance at the time of fabrication, and in which the influence of the manufacturing process is slight. In order to achieve the above described object, the present invention provides a manufacturing method of a control rod for a boiling water reactor constructed with sheaths having a U-shaped cross section attached to each end of a tie rod having a cruciform cross section, and rod, plate or oval tube cross section metal hafnium type neutron absorber material contained inside the sheaths, in which an anodized film is provided on a surface of the neutron absorber material as a pre-process of assembly of the neutron absorber material in the structure of the control rod.

Abstract: A control rod assembly for a boiling water reactor comprises a tie-rod of a cross-shaped section, and four sheaths. Each of the sheaths is of a U-shaped section and mounted to the respective arms of the tie-rod. One or more neutron absorber materials are disposed within a space defined by the arm and the sheath. The neutron absorber material is axially separated into two portions. One of two portions is supported by a supporting member. The other portion is suspended by a handle.

Abstract: A card conveying structure for card accessing devices, comprising: a casing defining a card inlet and a card guideway; a drive pulley and a driven pulley supported on one side of the card guideway by a first pivot axis and a second pivot axis, respectively, defining a zero or small angle relative to a vertical line perpendicular to a major surface of a card guided by the guideway; and an endless belt passed around the two pulleys, effective diameters of the first and second pulleys being selected in relation with spacings of the pivot axes relative to the card guideway so that a linear span ofthe belt may extend along the guideway and abut the major surface of the card. By urging the linear span of the belt against the card, the card may be conveyed by the movement of the belt. Alternatively, by slanting at least one of the pulleys towards the guideway until its periphery or the belt passed around it comes into contact with the card, the movement of the belt or the pulley can be transmitted to the card.

Abstract: A paper feeder for a printer which is adapted for feeding both continuous printing paper and cut sheet printing paper. A second frame which may carry the platen supports the rear end of a first frame which in turn supports the tractor feeder in such a manner that the first frame can be rotated backward from a first position adapted for feeding continuous paper to a second position adapted for making a room for mounting a paper guide to the printer. If the tractor feeder is adapted for pushing continuous paper towards the platen, continuous paper can be kept on the tractor feeder even when the second frame is at its second position.
