A main shaft apparatus (10) of a built-in motor system, wherein a rotary shaft (12) is provided with: a first cylindrical component (71) made of metal material; and a second cylindrical component (72) made of carbon fibre composite material, which is positioned on the outer peripheral surface of the first cylindrical component (71) and into the outer peripheral surface of which a rotor (20) fits. By virtue of this, the temperature increase of the rotary shaft and a bearing due to the heat produced by the rotor can be controlled and processing precision can be improved.

A profile stamping device comprises a carrying platform, a supporting member, a stamping module, elastic members and a first positioning plate. The supporting member comprises a plurality of stand columns and a fixing plate. The stamping module comprises an extensible member, a connecting plate and a punch. The extensible member is fixedly arranged on the fixing plate, and the extensible end of the extensible member is penetratingly arranged on the fixing plate. The connecting plate is arranged between the carrying platform and the fixing plate, and is fixedly connected with the extensible end which drives the connecting plate to move. The punch is fixedly arranged on the connecting plate and is far away from the extensible end. The connecting plate drives the punch to move. One end of each elastic member is fixedly connected with the connecting plate. The first positioning plate is connected with one ends, away from the connecting plate, of the elastic members. The distance between the first positioning plate and a profile is smaller than the distance between the punch and the profile. The first positioning plate moves to enable two ends thereof to be accommodated in guide rails and abutted against the side walls of the profile, and the two ends of the first positioning plates support the two side walls of the profile when the punch punches hooks, so that deformation of the profile is avoided. The invention further provides a profile stamping method.

By using a sintered body composed of 58-92.5% by mass of TiCN, 0.01-1% by mass of Ti, 0.01-2% by mass of TiC, 0.01-2% by mass of TiN and the balance of TaC, Ni and Cr, there can be obtained a sliding member, film-forming material and die for hot extrusion molding which exhibit high strength, high hardness, high toughness and high sliding properties in an environment of about 400-600 DEG C, and a hot extrusion molding apparatus using such a die for hot extrusion molding.

The invention provides a variable capacity hydraulic device. The variable capacity hydraulic device includes a housing, a cylinder, pistons, an inclined plate, an oil groove, a work piston and a servo mechanism, wherein the cylinder is arranged in the housing in the rotary way; the pistons are respectively inserted in a plurality of cylinder holes in the cylinder; the inclined plate is arranged on the pistons and on the opposite side end in the cylinder holes of the pistons, and is arranged in the sliding way relative to the opposite side end, and can move in the inclined way and can slide on the housing; the oil groove is formed on any one of the sliding surface of the housing and the sliding surface of the inclined plate, and is used for guaranteeing the sliding property between the housing and the inclined plate; the work piston is used for moving the inclined plate in the inclined way; and the servo mechanism supplies hydraulic oil to drive the work piston and supplies the secondary pressure generated by the servo mechanism to the oil groove.

The present invention provides a toning agent container composed of a container main body and a nut cap, capable of embodying good rotation sliding character and firmly supporting the container main body. the toning agent container includes at least the container main body (1) for storing the toning agent and the nut cap having a plurality of support means for supporting the container main body to rotate, the part of the support means contacted with the container main body is of a shape that is discontinuously contacted with the container main body in the rotating direction of the container main body.

The invention provides a flexible cable for intelligent equipment and a production process thereof. The cable comprises three power wire cores, two control wire core groups, a central reinforcing member, an inner sheath, a reinforcing layer and an outer sheath, wherein the two control wire core groups and the three power wire cores are arranged in a five-equal-division manner, and the central reinforcing member is arranged at a gap to form a cable core; and the inner sheath, the reinforcing layer and the outer sheath are sequentially arranged outside the cable core. The characteristics of wearresistance, high and low temperature resistance, pulling resistance, bending resistance, corrosion resistance and excellent insulation of the cable are improved, and the problems that the core of a pulling cable is easy to break and faults frequently occur in the prior art are solved.

The invention discloses an anti-rib-forming and anti-wrinkling printing film and a preparation method thereof, wherein by means of specific components and technologies, the total thickness, as well thickness of every layer and thickness ratio, of the printing film in an A/B/C layered lamination structure are defined, so that stiffness and thickness uniformity of the printing film are improved, thereby improving the anti-rib-forming and anti-wrinkling properties thereof.

The invention discloses a sliding block. The sliding block (10) is provided with a friction plate (12) and an adjustment mechanism (13). The friction plate (12) protrudes from a sliding block fitting surface (11) on the sliding block (10), and the height by which the friction plate (12) protrudes from the sliding block fitting surface (11) is adjusted by the adjustment mechanism (13). The invention also discloses a sliding device, which comprises a guide rail (20) and the sliding block (10) sliding along the guide rail, wherein the friction plate (12) and a guide rail fitting surface (21) on the guide rail (20) are in friction fit. The friction plate and the sliding block are a split type structure, and the height by which the friction plate protrudes from the sliding block fitting surface is adjusted by the adjustment mechanism, so that the sliding force can be constantly maintained in a needed range so as to ensure the sliding performance between parts.

The present invention relates to: a thermoplastic elastomer composition which comprises 5-30 parts by mass of an ethylene/alpha-olefin/unconjugated polyene copolymer (A), 20-40 parts by mass of a crystalline olefin resin (B) having a density of 0.90-0.92 g/cm<3>, 20-40 parts by mass of a high-density polyethylene (C) having a density of 0.94-0.97 g/cm<3>, 5-12 parts by mass of an ethylene/alpha-olefin copolymer (D) formed from ethylene and a C3-12 alpha-olefin, and 5-9 parts by mass of a silicone compound (E) (the sum of components (A), (B), (C), (D), and (E) is taken as 100 parts by mass); and an automotive glass run channel formed from the thermoplastic elastomer composition.
