Abstract: A cutting insert has top and bottom surfaces opposing each other and a side surface connecting them. A part of an intersecting ridge between the top and side surfaces functions as a cutting edge. On the side surface, a side surface portion adjacent to the intersecting ridge portion opposing the cutting edge intersects the top surface at an acute angle. At least on a part of a bottom surface, an inclined surface gradually approaching the top surface with increasing distance from a side surface portion on a side opposite to a cutting edge is formed. This allows a part of the cutting resistance to act on the side surface portion. As a result, friction resistance between the side surface portion and the side surface of an insert seat becomes larger, thereby suppressing a shifting of the cutting insert when cutting.

Abstract: Oil strainer has a housing having a suction port and a discharge port and a filtration element dividing an inside of the housing into a suction port side and a discharge port side. The filtration element has a first filtration member having a coarse filter, a second filtration member having a fine filter and stacked at an upstream side or a downstream side of the first filtration member and a retainer plate having a plurality of oil pass openings and retaining the first and second filtration members. The retainer plate is stacked at a downstream side of the first and second filtration members. The second filtration member has at least one opening portion so that a part of the oil bypasses the second filtration member. One of the first and second filtration members has protruding and depressed portions that touch the other of the first and second filtration members.

Abstract: A fuel container for fuel cells is equipped with a container main body, containing liquid fuel therein to be supplied to a fuel cell, equipped with a connecting port, for connecting with the fuel cell or a pressure adjusting device, and extruding means, for extruding the liquid fuel. The fuel container is also equipped with a partitioning member, which is slidably provided within the container main body, for partitioning the interior of the container main body into a fuel storage chamber, in which the liquid fuel is contained, and an extruding means housing chamber, in which the extruding means is housed. The fuel container is further equipped with a valve provided in the connecting port, for enabling or preventing the flow of the liquid fuel. The frictional force generated at the surfaces of the connector main body and the partitioning member, which are in sliding contact, is 10N or less.

Abstract: A pressure regulator, comprising a pressure regulating mechanism and a connector. A supply connecting tool (3) supplying a pressurized fluid to a body part (11) with the built-in pressure regulating mechanism (5) is connected to the connector (2) to secure excellent pressure regulating function by preventing the pressure regulating function from being affected by the connecting operation of the connecting tool and supply a fluid to stop the reverse flow of fluid caused by the attaching/detaching operations of the connecting tool. The connector (2) comprises a link member (544) openably operating a valve mechanism (6) according to the connecting operation of the supply connecting tool (3). The pressure regulating mechanism (5) comprises a pressure regulating valve (55) operated according to the deviation of a diaphragm (52) to regulate the pressurized fluid to a secondary pressure. The link member (544) is formed separately from the pressure regulating valve (55).

Abstract: The present invention provides a low electric conductivity, high heat radiation polymeric composition which includes a polymeric material and a carbon-based filler compounded with the polymeric material, wherein the carbon-based filler has an electron withdrawing agent grafted onto a surface of the carbon-based filler.

Abstract: A fuel container (1) for supplying fuel (F) to a fuel cell is constituted by: a container main body (2) having a sealed structure; an inner container (3) for housing the fuel therein, formed by a flexible bag provided within the container main body; a valve mechanism (4) for enabling/disabling supply of fuel, provided in the container main body (2) and in communication with the interior of the inner container (3); and compressed gas (G) for ejecting the fuel, sealed between the container main body (2) and the inner container (3). All of the structural components that contact the fuel (F) are formed of non-metallic materials. The fuel container (1) may also include an injection valve (5). In this case, a fuel injecting container reinjects fuel (F) into the fuel container (1), such that the fuel container (1) can be used repeatedly.

Abstract: The object of this invention is to provide an electrical signal filter for improving electrical characteristics and reliability of the electrical signal filter for use in a cable television by protecting it from moisture. In an electrical signal filter having a filter portion provided inside a cylinder-shaped shield case, the filter portion includes a first filter circuit and a second filter circuit respectively mounted on circuit boards, and a shield member arranged between the first filter and the second filter. In the electrical signal filter, a moisture-proof material is applied to an entire surface of the filter portion and a contact area where the cylinder-shaped shield case containing the circuit boards and the filter portion therein contacts external components.
