Abstract: A sheet processing apparatus for processing a sheet bundle includes a stitching unit having a head portion for driving staples into the sheet bundle and an anvil portion for receiving and bending the staples driven by the head portion, a feeding device for feeding the sheet bundle to a stitching position between the head portion and the anvil portion, a transport device for transporting the stitching unit to a position perpendicular to a sheet bundle feeding direction, a guide member for guiding the sheet bundle to the stitching position, and a supplement guide member. The supplement guide member retracts to a position that does not hinder the movement of the stitching unit when the stitching unit moves, and guides the sheet bundle to the guide member without a leading edge of the sheet bundle touching the upstream edge of the guide member.

Abstract: A sheet processing apparatus for folding a sheet bundle at a predetermined position includes paired rotating bodies for folding the sheet bundle having nip portions, a pressing device for pressing the predetermined position of the sheet bundle into the nip portions of the paired rotating bodies, and a device connected to the paired rotation bodies for providing rotation to the paired rotating bodies. A pulling force of the rotating bodies to pull the sheet bundle pressed into the nip portions of the rotating bodies has an amount which does not separate a sheet of the sheet bundle contacting the rotating bodies from the subsequent sheets in the sheet bundle when pulling the sheet bundle.

Abstract: An escape device for an inner mirror includes a stay base mounted on a ceiling of a cabin of a vehicle a stay suspended from and supported by the stay base and connected to the stay base pivotably about an axis extending horizontally in the direction of width of the vehicle, the stay having a mirror body attached to a lower portion thereof, and a stop mechanism provided between the stay base and the stay for stopping the pivotal movement of the stay about the axis relative to the stay base and thereby holding the stay in a suspended state in a normal mode of use and, when an external force exceeding a predetermined value is applied to the stay in the forward direction of the vehicle, disengaging the stay by the external force to allow the pivotal movement of the stay about the axis.

Abstract: The present invention provides a rubber composition containing a leather powder or gelatin powder, and a tire having a tread prepared from the rubber composition.

Abstract: A tire tread rubber composition having a two-peak tan.delta. characterized in that the temperature distribution curve for loss tangent (tan.delta.) has two peaks in the range from -120.degree. C. to +100.degree. C. is useful as a tire tread rubber composition.

Abstract: Rubber compositions for tire treads well balanced in the performances of rolling registance, sliding coefficient of friction on wet road surfaces and wear resistance and which are superior in the processability and workability, including at least 20 parts by weight of styrene-butadiene random copolymer prepared by using an organic lithium as a polymerization catalyst and coupled with a mono- or difunctional tin compound as well as a tri- or more functional compound and having a tin content of 300 ppm or more which is bonded to the polymer and further include a carbon black having the value of N.sub.2 SA/IA of 1.1 or more.

Abstract: A rubber composition comprising 40 to 100 parts by weight of carbon black per 100 parts by weight of a rubber component,(a) the rubber composition being characterized in that the rubber component contains, in 100 parts by weight thereof, at least 20 parts by weight of a block copolymer prepared by solution polymerization and comprising one unit of butadiene rubber portion and one unit of random-copolymerized styrene-butadiene rubber portion, the butadiene rubber portion having a vinyl content of 15 to 50%, the styrene-butadiene rubber portion having a vinyl content of 20 to 70% and a styrene content of 30 to 60%, the block copolymer having in its entirety a vinyl content of 15 to 60% and a styrene content of 5 to 30% at least 40% of the copolymer being coupled with a tin compound so that the coupled copolymer has a butadiene rubber terminal, the coupled copolymer having only a single Tg at a temperature of up to -60.degree. C.

Abstract: This invention is a rubber composition for a tire tread of 100 parts by weight (pbw) diene system rubber to which are added x pbw of carbon black and y pbw of softening agent. The softening agent contains z pbw of liquid polymer. The amounts of x, y and z are described by the inequalities (5/8)x-20.ltoreq.y.ltoreq.x and (y/5)+5.ltoreq.z. The liquid polymer has a flow points of 20.degree. C. or below. The rubber composition provided here gives a tire tread with improved performance in terms of grade climbing ability, braking and standing start, on ice as well as on snow. Besides, the service life of the rubber is prolonged, and tread performance deterioration is reduced to a minimum.

Abstract: A rubber tire composition, comprising:from 20 to 150 parts by weight of carbon black incorporated in 100 parts by weight of rubber;at least 30 parts by weight of said rubber being a star type solution polymerized random styrene-butadiene copolymer rubber comprising 10% to 20% by weight of styrene units and the balance of butadiene units; said styrene units having at least 40% by weight of the single isolated styrene units which are separated from each other and 5% by weight or less of the styrene units in the form of long chain blocks each consisting of 8 or more styrene units bound to each other, based on the entire weight of said styrene units in the copolymer; said butadiene units having 35% to 50% by mole of butadiene units in the form of 1,2-vinyl structure based on the entire mole of said butadiene units in the copolymer; said styrene-butadiene copolymer rubber having the ratio (Mw/Mn) of 1.2 to 3.
