Abstract: A seat frame assembling unit includes: a setting device and a setting robot. The setting device is driven in a state where side frames, a connecting frame, a pan frame, a member frame and an upper frame are arranged. The setting robot installs the side frames side by side and subsequently installs the connecting frame, the pan frame, the member frame and the upper frame between the side frames. The setting device moves the side frames to positions in which the side frames are to be assembled with the connecting frame, the pan frame, the member frame and the upper frame.

Abstract: A light receiving element (1) according to an embodiment of the disclosure includes a semiconductor layer (20) in which a photodiode having a PIN structure is provided in a mesa portion having a pillar shape. The photodiode includes a first conductive layer (21), an optical absorption layer (23), and a second conductive layer (24) having a light incident surface. In the light receiving element (1), the semiconductor layer (20) includes, in the vicinity of an interface between the first conductive layer (21) and the optical absorption layer (23), a constricted portion (26) that is the most constricted of the first conductive layer (21). The interface has an end exposed on an internal surface of the constricted portion (26).

Abstract: According to the present specification there is disclosed a porous film having a number of throughholes extending from one side to the other side, obtained by molding into a sheet form a resin composition comprising an ethylene-.alpha.-olefin copolymer, a thermoplastic elastomer and an inorganic filler and then subjecting the sheet to stretching for orientation. Said porous film has excellent flexibility, stretchability and moisture permeability. These properties are made possible by using individual components in particular proportions, molding the resulting composition into a sheet form and then stretching the sheet to form fine throughholes therein so as to have a moisture permeability of 2,000 g/m.sup.2.24 hr or more.

Abstract: A stretching device for stretching a tubular film includes a mandrel including a stretching section, a pair of payoff nip rolls disposed upstream of the mandrel and a pair of take-up nip rolls disposed downstream of the mandrel. The stretching section of the mandrel is comprised of a plurality of rings arranged substantially concentrically in spaced-apart relationship in the travelling direction of the tubular film. The outside diameter of a ring on the downstream side is larger than that of a ring on the upstream side. Each of the rings has a plurality of rotating members mounted rotatably, and the plurality of rotating members define an outer circumferential ring edge which is generally smoothly circular.

Abstract: A process for the preparation of soft porous sheets, comprises forming into a sheet a composition comprising (i) 40 to 80% by weight of an inorganic filler and (ii) 60 to 20% by weight of a polyolefin type thermoplastic elastomer composition comprising at least 50% by weight of a polyolefin type thermoplastic elastomer substantially free of a polar group, in which the tensile stress at a temperature of 25.degree. C. under 100% stretching (100% modulus) is 10 to 100 Kg/cm.sup.2, the elongation at break under stretching is at least 100% and the permanent strain under 100% stretching is less than 50% and up to 50% by weight of a thermoplastic plastomer, and stretching the sheet at a temperature lower than the softening temperature of the polyolefin type thermoplastic elastomer. A porous sheet obtained according to this process has a good combination of flexibility, air permeability and water resistance.
