Abstract: Provided is a handrail device in first and second unit booms adjacent to each other, having high strength. The handrail device includes: a pair of first poles; a pair of second poles; a first main rope stretched between the pair of first poles; a second safety line stretched between the pair of second poles; a first pole support member and a second pole support member that support the first poles and the second poles, respectively; first and second connection member; a first stay rope stretched between the first pole and the second connection member; and a second stay rope stretched between the second pole and the first connection member. The first pole support member and the first connection member are fixed to a common first fixation member, and a second pole support member and the second connection member are fixed to a common second fixation member.

Abstract: To reduce the number of places where dimension control regarding an attachment position of a coupling portion to a structure is required. A first coupling portion includes a first pin receiving portion into which a coupling pin can be inserted, and a load transmitting portion integrally provided with the first pin receiving portion. A second coupling portion includes a second pin receiving portion into which the coupling pin can be inserted, and a load receiving portion integrally provided with the second pin receiving portion. The first pin receiving portion and the second pin receiving portion match with each other so as to detachably attach the coupling pin in a state where the load transmitting portion and the load receiving portion are in contact with each other.

Abstract: Provided is a method for producing a high-strength electrode film for an EDLC, where scraps generated when producing the electrode film are reusable. The method for producing an electrode film for an electric double-layer capacitor includes a step of kneading a carbonaceous powder, a conductive assistant, and a fluororesin binder, and producing a shaped product from the obtained kneaded product, a step of pulverizing the shaped product to produce a modifying material having an average particle diameter of 5 to 100 ?m, and a step of kneading a carbonaceous powder, a conductive assistant, a fluororesin, and the modifying material in a ratio of 1 to 40% by weight of the modifying material with respect to 100% by weight in total of the carbonaceous powder, the conductive assistant, the fluororesin, and the modifying material, and rolling the obtained kneaded product to produce an electrode film for an electric double-layer capacitor.

Abstract: Disclosed is a raisable-lowerable member which comprises a boom and a jib. The boom comprises a first supporting portion configured to rotatably support a jib foot when the jib is set in a protruding posture; and a second supporting portion configured to rotatably support a supportable portion of the jib when the jib is set in an enfolded posture. A position adjusting and holding unit of the jib is configured to couple, to the frame, a specific site of the second link in such a manner that a relative position of the second link with respect to the frame in a rotational direction of the second link is adjustably changed to allow the rotational axis of the second joint portion to become coincident with the rotational axis of the jib foot, and to hold the second link at the changed relative position.

Abstract: In a lattice boom, a first reinforcing lattice member includes a first reinforcing pipe which has a portion extending in the same direction as a first main member of a base boom and which is separated outward from a first side surface of the base boom and a first mounting part which is provided on the first reinforcing pipe and which is mounted to the first main member so as to transfer a load acting on the first main member in an axial direction of the first main member to the first reinforcing pipe, and a second reinforcing lattice member includes a second reinforcing pipe which has a portion extending in the same direction as a second main member of the base boom and which is separated outward from a second side surface of the base boom and a second mounting part which is provided on the second reinforcing pipe and which is mounted to the second main member so as to transfer a load acting on the second main member in an axial direction of the second main member to the second reinforcing pipe.

Abstract: A dot matrix printer having a platen, a carriage, and a print head mounted on the carriage. A paper guide is secured to the carriage. A ribbon mask made of a resilient plate is attached to the paper guide. A cantilevered resilient plate is formed in the ribbon mask so as to be abutted on a front end of the print head to form a path for a ribbon between the resilient plate and the print head.

Abstract: A lubricating oil feeder for supplying an air-oil mixture containing compressed air and lubricating oil to oil receiving units including a pump for generating compressed air, an air supply pipe coupled to the pump, air induction pipes for introducing the compressed air from the pump in the oil receiving units, and oil supply source for intermittently discharging lubricating oil from the intermittent oil supply source to the oil receiving units, and oil injection devices for intermittently supplying a small fixed quantity of lubricating oil from the intermittent oil supply source to the lubricating oil supply pipes. The oil injection devices are installed between the intermittent oil supply source and the lubricating oil supply pipes, and the oil lines are coupled to the air induction pipes through the lubricating oil supply pipes and check valves.
