Abstract: A connecting structure for piping members facilitates connection thereof and ensures prevention of liquid leakage. A first piping member includes a first channel, and at least one first joint surface in which at least one first opening communicating with the first channel and a first annular groove are provided. A second piping member includes a second channel, and at least one second joint surface in which at least one second opening communicating with the second channel and a second annular groove are provided. A sleeve for connecting the first and second piping members includes a central bore. The sleeve includes a pair of inserting sections and a partition therebetween. The inserting sections are thinner radially as compared to the partition and are configured to accommodate at least one elastic body which provides a seal when the inserting sections are press-inserted into the first and second annular grooves.

Abstract: An optical-pickup feeding apparatus includes a pickup base on which an optical pickup is mounted, which includes a sliding bearing with a lubricant agent; and a lead screw that is slidably fitted into the sliding bearing. A peripheral surface of a screw thread of the lead screw is formed in a shape of a circular arc.

Abstract: The present invention provides a connecting structure for piping members that are easy to connect and ensure prevention of liquid leakage even if sealing performance deteriorates due to weakened crimping force of the connected portion as a result from creep caused by changes in fluid pressure and temperature over prolonged periods and connected parts are susceptible to separation owing to looseness occurring in securing members.

Abstract: There is provided a substrate material, for an HDD suspension, which has excellent adhesion between a stainless steel foil and an insulating resin layer and maintains high etching performance by preventing metal components in the stainless steel from diffusing into the insulating resin layer. The substrate material for an HDD suspension of the invention is a material obtained by shaping a stainless steel foil, wherein, on the surface of the stainless steel foil and on at least one side thereof, there are laminated, at least, a covering layer made chiefly of either one or both of a metal oxide and a metal hydroxide with chromium excluded as the metal species, and an insulating resin layer.

Abstract: This invention relates to a graphite material for negative electrode of lithium secondary battery. This graphite material is obtained by carbonizing the pulverized green coke to yield coke, adding one kind or more of boron or a compound thereof to the coke, graphitizing the resulting mixture and controlling the particle size of the product graphite. This graphite material for negative electrode is characterized by showing a tap density of 0.95 g/cm3 or more after tapping 20 times or 1.15 g/cm3 or more after tapping 300 times and a BET specific surface area of 1.5 m2/g or less. A lithium secondary battery made by the use of this graphite material for negative electrode has a large discharge capacity and suffers little loss during charging and discharging.

Abstract: A crushing chamber is formed between a concave liner and a mantle liner. The concave liner has a first area surface having a length of T to ?2T; a second and a third area surface; which surfaces are gradually inclined from the side of the inlet for the crushing chamber. The mantle liner has a first tapered surface having a length of greater than T, a cross angle of less than 20° and an inclination angle of greater than 60°; a second tapered surface having a length of greater than 0.5T and a cross angle of 5° to 10°; and a third tapered surface having an inclination angle of 45° to 50°. The area surfaces as well as the tapered surfaces are continuously arranged in a curvilinear manner. The shapes enhance the throughput of goods in a good fine-crushing performance, reducing the uneven abrasion due to the action.
