Abstract: Provided are a pile press-in device and a pile press-in method that allow an efficient construction even when electrically powered devices and hydraulic devices coexist in order to give drive members a driving force. A pile press-in device (1) comprises a chuck (5) for gripping and rotating a pile (4) in order to press the pile (4) into a ground while rotating the pile (4). The pile press-in device (1) causes electric motors (6) corresponding to the electrically powered device of the invention to give the chuck (5) a driving force for the rotation. The chuck (5) is moved up and down by lift cylinders (7) which are hydraulically powered hydraulic devices. An integrated control board (50) controls the electric motors (6) and the lift cylinders (7) in an interlocked manner.

Abstract: A pile press-in machine that receives reaction force from an existing pile to press in a new pile, includes: a reaction force block that grips the existing pile by a clamp to receive the reaction force; a platform that is horizontally movable relative to the reaction force block; and a press-in block that is coupled to the platform, supported to be freely lifted up and down with respect to the platform at a front of the clamp, and grips and presses in the new pile, wherein a plurality of kinds of the reaction force blocks each according to a kind and size of the existing pile are freely attachable to and detachable from one platform.

Abstract: Provided are a pile joint, a pile coupling structure, and a pile coupling method that allow firm uniting of piles to be coupled. A joint (10) for coupling two piles (12) comprises: a tubular body (16) into which each pile (12) provided with a key (14) on a periphery thereof is inserted through an end (16A) of the body (16); and a fitting portion (22) formed on the body (16) so as to be fitted to the key (14) by the insertion and rotation of the pile (12). The fitting portion (22) is formed with: a tapered shape having a surface (22A) that is inclined so as to become distant from the end (16A) of the body (16) as the surface (22A) extends in the direction of rotation of the pile (12); or a wedge shape for fitting between a projection and a pile.

Abstract: A manufacturing method of a concrete pile is shown. The method includes the following, that is, pouring concrete in the pile molding space, reducing the pile molding space to compress and mold the concrete, draining water drained from the concrete by compression and molding outside of the formwork from the drainage hole, and holding the concrete a predetermined amount of time to harden the concrete. The formwork includes an outer formwork that molds an outer wall surface of the concrete pile, an inner formwork that molds an inner wall surface of a hollow space of the concrete pile, and a pair of end formwork that mold upper and lower end surfaces of the concrete pile. The drainage hole is a gap between adjacent components when the mold is tightened, and the gap is configured to be capable of being opened larger during cleaning than when the mold is tightened.

Abstract: A parking system includes an inventory status storage storing the status of inventory of a bicycle, two-wheeled vehicle, or car, and a control system that controls the status of inventory of the bicycle, two-wheeled vehicle, or car and controls check-in and check-out of the bicycle, two-wheeled vehicle, or car based on data stored in the inventory status storage. The parking system further includes a cooperative control unit for communicating with an external rental operator's server, converting instruction data on check-in and check-out transmitted from the server to commands processable for the control system, and instructing to do check-in and check-out.

Abstract: A ground fish meat (surimi) is produced by bleaching raw fish meat with water in the presence of a quality-improving agent comprising calcium chloride, potassium chloride, or a mixture of sodium chloride with potassium chloride or calcium chloride in an amount of 0.01 to 3.0% of the total weight of the raw fish meat and the bleaching water. During the bleaching, the fish meat is forcibly stirred. Then, the thus bleached fish meat is ground to produce a surimi product.

Abstract: A curling iron for curling or waving a lock of hair twined around a heated iron rod, wherein an iron rod/clamping member assembly is mounted rotatably on the iron handle and mechanical or electrical means is provided for rotating the assembly to facilitate the curling or waving operation. Preferably, the iron rod/clamping member assembly is mounted detachably on a rotatable shaft housed within the iron handle to enable ready replacement of the assembly as well as angular positioning of the assembly with respect to the iron handle.

Abstract: An electrostatic precipitator with at least one pair of spaced, flat-plate grounded dust collecting electrodes and a floating, insulated dust collecting flat-plate electrode arranged in the center of each space between the grounded dust collecting electrodes parallel to the gas flow and provided at its edges at fixed intervals with sets of needle-shaped discharge electrodes.The needles are fabricated along an outer longitudinal edge of a channel bracket member by welding or the like at precise equal spacings. Plural bracket members are riveted along the respective leading and trailing edges of each floating flat electrode plate in such a fashion that the tips of the needles are aligned vertically in the precipitator chamber. The diameter of the needle-shaped discharge electrodes is smaller than approximately 5 mm and the tips of the needle-shaped electrodes have a maximum radius of approximately 0.
