Abstract: A gas combustion type driving tool is provided with a combustion portion; a fuel container for containing a fuel; an electromagnetic valve device for injecting the fuel into the combustion portion; and a grip portion. A distance from the fuel container to the combustion portion is set substantially equal to or less than a distance from the electromagnetic valve device (24) to the combustion portion.

Abstract: In a connected fastener assembly, the shaft sections of multiple fasteners are connected using a connecting band made of a synthetic resin. Retaining sections for allowing the shaft sections of the fasteners to be inserted therein and connecting sections for connecting the adjacent retaining sections are formed continuously. The connecting sections are offset from the center line “a” connecting the centers of the adjacent fasteners (retaining sections).

Abstract: In a connecting fastener consisting of a plurality of fasteners connected through a connecting member of synthetic resin, the connecting member includes a ring-shaped portion attached to so as to encircle the shaft of each of the fasteners to be connected and a connecting portion connected to the ring-shaped portions encircling adjacent fasteners. When the fasteners each suffers from the blow at the time of driving by a fastener driving tool, the ring-shaped portions each has strength enough to be held over the shaft and the connecting portion has strength enough to be broken.

Abstract: A gas combustion type driving tool is provided with a fuel container storing portion, a lid that covers an opening of the fuel container storing portion, a connecting section which is formed in the fuel container storing portion and to which a nozzle of a fuel container is connected; and a cover member that covers the connecting section. The fuel container storing portion is adapted so that the fuel container stored within the fuel container storing portion is attachable and detachable by opening the lid. The connecting section is adapted to be exposed to an outside of the tool by opening the cover member.

Abstract: A connected fastener assembly is formed by fitting a shaft guide on a shaft section of each fastener, by connecting the fasteners using two connecting sheets made of a synthetic resin and disposed on upper and lower sides of the shaft guides. Since the connecting sheets have through holes thorough which the fasteners pass and connecting sections formed so as to be easy to bend or difficult to bend in the width direction, the connected fastener assembly can be formed into a straight type or a coil type. In a connected fastener assembly, shaft sections of a plurality of fasteners are connected by a connecting band formed of a thin sheet of a synthetic resin. Ring-shaped retaining sections for retaining the shaft sections are formed at constant intervals in the connecting bands. The ring-shaped retaining sections are disposed so as to be overlaid on shaft guides made of soft materials and fitted on the shaft sections. Each of the shaft guides is formed into a cylindrical shape.

Abstract: A power tool includes a striking cylinder, a striking piston slidably housed in the striking cylinder, a driver coupled to a bottom surface of the striking piston, and a cushioning mechanism configured to absorb an impact of striking a fastener with the driver when the striking piston is driven. The cushioning mechanism includes a housing formed below the striking cylinder, and a bumper housed in the housing to receive the bottom surface of the striking piston. The bumper is formed in a tubular shape, a wall thickness of a central section of the bumper is greater than wall thicknesses of an upper section and a lower section of the bumper, and the wall thicknesses of the upper section and the lower section are substantially the same.

Abstract: An elevator group control system for controlling multiple elevators cars each of which serves a plurality of floors includes a route preparation section which, at a time of assigning a hall call to one of the elevator cars, calculates a future trajectory for each of the elevator cars. The future trajectory for each elevator is for a case in which the hall call is assigned to the elevator car. A selecting unit which determines a selected one of the elevator cars to which the hall call is to be assigned using the calculated future trajectories.

Abstract: An elevator group control system includes a reference route generating portion, which for each elevator, generates a reference route which the elevator should follow with respect to the time axis and position axis; and an assignment portion which selects an elevator for assignment to a generated hall call so as to make the actual trajectory of each elevator closer to its reference route. Reference routes which guide the cage's trajectory into temporally equal interval condition are generated, and car assignment is executed to allow the cages to settle in temporally equal interval condition over a long period of time.

Abstract: A method and a display for elevator allocation evaluating are provided. When an elevator allocated to a hall call is selected by employing two different view points such as a real and a future call evaluation index, an elevator allocation reason and a balance between the two view points can be easily grasped. An elevator allocated to a hall call is evaluated on orthogonal coordinates in which the real call evaluation index and the future call evaluation index are defined as an X and a Y coordinate axis. Evaluation indexes of first to fourth elevator cars are evaluated by employing contour lines of a synthetic evaluation function, which is represented as the real and the future call evaluation index. A weight for allocating is displayed visually.
