摘要:
A contact includes a plate with a width that ranges from 0.1 mm or more to 1 mm or less, and a stress concentrated place, where a surface roughness (Ra) on the stress concentrated place is 0.2 μm or less. When samples whose surface roughness Ra is 0.040 μm, 0.080 μm, 0.120 μm, and 0.180 μm were used to study a number of repetitive fracture times, as the surface roughness Ra was smaller, the number of repetitive fracture times became larger. Particularly, it is found that the surface roughness Ra may be 0.200 μm or less in order to satisfy 3000 times as a number of operating times of the battery connector. Further, the surface roughness Ra may be 0.080 μm or less in order to satisfy 6000 times as the number of operating times when a safety factor is 2.

A humidifier that suppresses formation of a slime, a scale, and a dew bridge in a lower portion of a humidifying member thereby preventing degradation in humidifying performance. The humidifier includes one or more porous metal bodies serving as the humidifying member and including therein a plurality of voids, a fan that blows air to the porous metal body, a water-supplying device (a supply pipe, a reservoir, and a nozzle) that supplies water to the porous metal body, and the porous metal body includes a tip portion formed in a lower end portion, in a protruding shape or a pointed shape.

A mounting structure of a flexible printed circuit board and a sliding-type electronic device is provided by which a too large increase in thickness of devices can be avoided and a pair of housings can be slid relatively in a bending and slanting direction. In the mounting structure, an upper housing 12 and a lower housing 22 coupled in a freely slidable manner are electrically connected to each other by a flexible printed circuit board folded back to be routed between slide facing surfaces 12b and 22a of both the housings and the height of a side wall surface 12c and 22c of the upper housing and lower housing changes in a bending manner along the direction of freely sliding and, in the slide facing surfaces of the upper housing and lower housing, concave space portions 15 and 25 to accommodate the change in curvature and in position of a folding-back portion 31a caused by sliding motion between the upper housing and lower housing are disposed.

A contactor including a bellows body, a fixed portion connected to one end of the bellows body, and a movable portion, connected to the other end of the bellows body, where the movable portion is configured to be depressed to compress the bellows body and to bring a connecting projection, projectingly provided on the bellow body, into contact with the bellows body itself.
摘要:
The present invention provides a conductive polymer in which, when being formed into a coating film, foreign materials are difficult to be generated even the passage of time and a quality control method for a conductive polymer and has a repeating unit which is represented by the following general formula (1). The present invention also provides a quality control method for conductive polymers wherein conductive polymers with an area ratio (Y/X) of 0.60 or less are selected. In the formula R1 to R4 are each independently —H, a linear or branched alkyl group having 1 to 24 carbon atoms, a linear or branched alkoxy group having 1 to 24 carbon atoms, an acidic group, a hydroxyl group, a nitro group, —F, —Cl, —Br or —I; and at least one of R1 to R4 is an acidic group or a salt thereof.[Chemical Formula 1]
摘要:
There are provided a hinge unit and portable terminal, even when a display housing is inverted to respond to demands for thin and light weight structure and high design quality, its display housing is always in a proper position. The display housing 1 has a display device 2 at its display housing front 1a. The display device 2 is made up of, for example, a liquid crystal display device and performs predetermined displaying. The shaft fitting section 3 is fitted in an end terminal region of one side of the display housing. A shaft 4 is inserted into the shaft fitting section 3 to support the display housing 1 in a manner to be freely inverted and fitted to the shaft fitting section 3 so that an axial center of the inverting axis forms a predetermined angle with a display surface of the display device 2.
摘要:
A thermo-reactive flame-retardant adhesive tape having high flame-retardancy and a method for producing the same are disclosed. The adhesive tape comprises a substrate and a solvent-less type photo-curing pressure-sensitive adhesive applied onto the substrate, the solvent-less type photo-curing pressure-sensitive adhesive comprising a photo-curing pressure-sensitive adhesive, as well as a dripping inhibitor and a flame retardant both added into the photo-curing pressure-sensitive adhesive, the photo-curing pressure-sensitive adhesive containing as main components at least a (metha)acrylic acid alkyl ester monomer, a polar group-containing monomer, and a photo-polymerization initiator. Based on 100 parts by weight of the photo-curing pressure-sensitive adhesive, 5-50 parts by weight of a hydroxyl-containing monomer having a photo-active functional group, as well as 5-100 parts by weight of phosphazene and 10-200 parts by weight of hydrated alumina, are added as the dripping inhibitor and the flame retardant, respectively, to the photo-curing pressure-sensitive adhesive.
