The invention relates to a mini type mulching film recovery machine of tobacco in seedling stage, which mainly comprises a seedling protective plate (1), a depth limiting land wheel (7), a break shovel (2), a stander (11), a large chain wheel (13), a small chain wheel (17), a gear wheel (18), a pinion (22), a film rolling roll (15), a universal joint (16), a position horizontal adjusting rod (20)of the film rolling roll and an angle vertical adjusting rod (25) of the film rolling roll. The gear wheel (18) and the pinion (22) are meshed to make the film rolling roll (15) and a driving wheel toreversely rotate to roll the film, so earth rolling is avoided; the inclined angle of the film rolling roll (15) can be adjusted by the universal joint (16), the angle vertical adjusting rod (25) ofthe film rolling roll and the position horizontal adjusting rod (20) of the film rolling roll according to the inclined angle of a tobacco ribbing surface; and the film rolling roll (15) is always well attached to the inclined plane of tobacco ribbing by the depth limiting land wheel (7) under the action of a depth limiting spring (8). The small tobacco seedling stage mulching recovery machine isused for recovering mulching films of seedling-stage tobacco planted in ridge culture, belongs to field tending machinery and is also suitable for recovering mulching films of cotton and other flat planting crops.

The present invention provides a linear fastening system capable of rapid engagement and disengagement. More specifically, the system utilizes a cooperating collet member and a compression ring member which are constructed and arranged to slip easily over a shank member. The fastener system is secured by linearly traversing a compression member in an overlapping fashion over the collet member thereby utilizing ribbed surfaces to compress the collet member to grip the outer surface of the shank member. In this manner, the linear fastener system is capable of providing a precise, secure, and reproducible connection between multiple components without the need to apply rotational torque to the assembly.

An electrical cable and a method for manufacturing the electrical cable are provided in which a plurality of insulated conductors have an inner protective layer extruded thereabout. A plurality of longitudinally extending ribs or fins or exterior ribbed or finned surfaces are formed outward of the inner protective layer between which exist a plurality of voids. An outer insulation layer can be formed in the same operation as the fins or ribbed surface and the inner layer or in a subsequent operation.

A PEFC (polymer electrolyte fuel cell) has a cathode separator for a PEFC working at 100° C. or higher. The cathode separator has gas passages to fed oxidant gas. Each of the passages increases the sectional area thereof with going down stream along with gas flow. That is, the PEFC has the cathode separator whose passage is configured that the downstream side sectional area thereof is larger than the upstream side sectional area thereof. In addition, the area of contact between the rib surface of the anode separator and a diffusion layer of an anode is larger than the area of contact between the rib surface of the cathode separator and a diffusion layer of the cathode.

An insert filter designed for press-fitting into airway port of hardware apparatus of a railway air brake system whereby the airway ports have at least two different diameters, the insert filter having a ring member defining an opening, a plurality of spaced support ribs extending from a first side of the ring member and intersecting at a location spaced from that first side of the ring member, and a screen mesh supported by the plurality of spaced rib supports defining a volume adjacent to the opening through the ring member. Each of said support ribs having a primary interface rib surface adjacent to an outer edge surface of the ring member adapted to engage inner edge surfaces of a larger, first airway port, and a secondary interface rib surface adjacent to the primary interface rib surface adapted to engage inner edge surfaces of a smaller second airway port.

The invention relates to the dual face digital controlled machining of complex structures that composed of horizontal beam components, positioned using two holes set on the process boss with compression slot set around the component, horizontally set frame component using one side of two holes to position, two process holes set on the boss which set surrounding the component with rib surface as the positioning face, cushion plate as the tool, using countersunk bolt compressing the fixed plate, horizontal set wall plate components using special vacuum sucking tool, machining from the side with less slot, then regarding it as the positioning baseline. It changes the process complexity of existing techniques. It is simple in locating, stable, simple in compression, good in universality, free from special making, avoiding component deformation, compression damage or dimension precision worsening due to clamp change. It can be co-used with other components with certain universality, economical in tooling.

A tapered roller bearing comprises an inner ring having a conical surface-like raceway surface in it outer periphery and formed with a cone back face rib and a cone front face rib on the opposite sides of the raceway, an outer ring having a conical surface-like raceway in its inner periphery, a plurality of tapered rollers interposed between the raceways of the inner and outer rings, and a cage for holding the tapered rollers in predetermined circumferential intervals, wherein the ratio R/R_BASE of the radius of curvature R of the large end face (32) of the tapered roller (30) to the distance R_BASE from the apex of cone of the tapered roller (30) to the cone back face rib surface (18) of the inner ring (10) is set at 0.75 to 0.87, and the end face deflection of the large end face (32) of the tapered roller (30) is 3 μm or less.
