A reciprocating vibration generator of a structure enabling force of a reciprocating vibrating body striking a coil to be absorbed by magnetic fluid even if an external impact force is applied, that is, a reciprocating vibration generator provided in a case body 100 with an upper plate spring 40 and a lower plate spring 50 for supporting a ring-shaped weight 20 having a ring-shaped permanent magnet 30 comprised of a combination of semi-ring-shaped permanent magnets 30R, 30L at its inner circumference side so as to be able to reciprocally vibrate in a vertical direction and a cylindrical excitation coil 60 passing through the inside of the ring-shaped permanent magnet 30 in the vertical direction and generating a reciprocating vibrating magnetic field, wherein the semi-ring-shaped permanent magnets 30R, 30L are magnetized in a direction spanning the inner circumferential surface and outer circumferential surface, the inner circumferential surface and top and bottom end faces of the semi-ring-shaped permanent magnet 30R, 30L are covered by magnetic fluid F, and a gap between the inner circumferential surface and the outer circumferential surface of the excitation coil 60 is filled with magnetic fluid F.

The orbiting base plate has a compression side surface and a back pressure chamber side surface. The gas passage has an opening in the compression side surface of the orbiting base plate between portions of the orbiting spiral wall that face each other, and the gas passage has an opening in the back pressure side surface at a position that faces an area on a radially inner side than the outer circumference of the bearing, so as to feed the refrigerant gas in the compression chamber to the back pressure chamber.

Disclosed is a wheel made of lightweight alloy having superior rigidity in the vertical and horizontal directions. A wheel made of lightweight alloy (10) for use with vehicles comprises a disc portion (6); and an inner rim portion (8) arranged in a standing state upon the rim of the disc portion (6). The inner rim portion (8) further comprises a well portion (11) arranged in a standing state vertically upon the rim of the disc portion (6); a rim center portion (12) that is serially connected to the well portion (11); and an inner rim flange portion (13) that is connected to a connecting portion (15) of the leading edge of the rim center portion (12). The inner rim flange portion (13) further comprises a perimeter flange (13a), which extends outward from the connecting portion (15); and an inner circumference flange (13b), which extends inward from the connecting portion (15). The edge of the perimeter flange (13a) curves in the axial direction.

A radio communication method capable of eliminating a blocking effect caused by a collision of many pieces of data is provided. The radio communication method relaying data from a lower terminal to an upper terminal, includes: a step of determining the number of lower terminals connectable to the upper terminal; a step of connecting the lower terminal and the upper terminal based on the determined connectable number; a step of transmitting a first data from the lower terminal to the upper terminal connected to each other; a step of causing the upper terminal to receive the first data transmitted from the lower terminal; and a step of combining the first data received by the upper terminal and a second data to be transmitted from the upper terminal and creating combined data; and a step causing the upper terminal transmitting the combined data to a further upper terminal.

A slide wiring device includes: a metal rail; a slider slidably arranged on the metal rail; a wire harness in which a plurality of electric wires are armored by an armoring member made of a resin, the wire harness being coupled to the slider and configured to move in the metal rail along with movement of the slider; and a resin rail that is arranged inside the metal rail, and is configured to confine movement of the armoring member. The armoring member is configured to move on the resin rail along with the movement of the slider.

The invention provides a chain drive device which can improve the transmission efficiency of a non-lining roller chain and improve the durability of an inner plate and a joint pin at the same time, alleviates the impact when a roller and a sprocket begin to engage with each other, reduces noise, and improves the durability of the roller and the joint pin. In the non-lining roller chain (C) of the chain drive device, the joint pin (140) which cannot move relatively to an outer plate (120) is embedded in a via hole (136) in the inner plate (130). An oil film having lubricating oil is formed between the joint pin (140) and the roller which can be rotatably directly supported by the joint pin (140). In the chain (C), only the inner plate (130) is in sliding contact with sliding contact surfaces (114, 118) of a chain guiding device through a back surface (133) of the inner plate (130). The back surface (133) has an arc contact part (134) formed in a chain-heading direction.

A cutting insert provided with an upper surface, side surfaces, and cutting edges provided at portions at which the upper surface and the side surfaces intersect with each other. Each side surface has grooves reaching the upper surface so as to divide the cutting edge into small cutting edges. Projections are provided on the upper surface at positions to which the grooves extend.
