An outer tubular blade is provided in the tip part of the outer tube. The tip of the outer blade is open and has a slot extending from the tip in a peripheral wall and forming a blade part at an edge of the slot.

Abstract: A high shock-absorbing automobile bumper with a smooth outer surface which may be manufactured by loading a preformed surface skin member into a blow mold, and then blowing a parison in the mold so that the blow parison is bonded to the surface skin member. The result is a hollow cushioning body firmly bonded to the surface skin member.

Abstract: A hydrostatic transmission with a pair of pump/motor connected in a closed loop state by a pair of hydrostatic circuit. The hydrostatic transmission comprises a differential pressure detecting means which detects the differential pressure between the circuits and a displacement correcting means which, in case an operation to establish a neutral status has been carried out, controls the displacement volume of the pump/motor on the side where the pumping action is carried out toward a direction in which the magnitude of this differential pressure is held within a set range.In case the set range is set to a value with which a vehicle cannot run, the phenomenon of creep running will not occur.

Abstract: A turret tool post for a machine tool has a turret having a plurality of turret faces each equipped with a tool for machining, a turret shaft for rotating the turret, a cam follower provided on the turret shaft, a cam having a cam surface engaged with the cam follower to cause the cam follower to rotate, and an indexing motor for driving the cam to index the turret faces. A straight raceway portion is formed on the cam surface of the cam so that the cam follower is not driven to rotate through a predetermined angle. Also disclosed is an apparatus for controlling indexing of the turret tool post which has a turret controller for controlling the rotation of the indexing motor. The speed of the indexing motor is controlled in accordance with whether a door attached to a cover covering the turret and other elements is open or closed.

Abstract: This display board consists of the transparent acrylic plastic plates in which surface desired letters or pictures are grooved, and a panel made by fitting together a number of the bricks of transparent acrylic plastic. The light receiving edges of the plate, and the light receiving edge and the light emerging edge of the brick are sandpapered in order to make lights enter and emerge from the edge to maximum extent. The light receiving edges of the plates and bricks are colored with a desired to produce a colored light. When light-bulbs with refractors properly positioned at the light receiving edges of the plate and the brick are turned on, the colored lights withthe same color of the dye coloured the edges will emerge from the grooves cut in the plate and from the emerging edge of the brick. For uniform illuminant intensity of the grooves cut in the plate, the depths of grooves are adjusted to be deeper around the center of the plate than around its periphery.

Abstract: A suction controlled gear ring pump effects a continuous decrease of the vacuum occurring in the feed cells of the pump at higher rotational speeds due to the long movement path of the feed cells from the end of the suction region to the beginning of the discharge opening and the thereby occurring diminution of the feed cells. In order to prevent squeeze oil when working at a lower rotating speed, the feed cells positioned successively in the feed direction are connected between the teeth respectively with the neighboring feed cells by overflow channels extending through the gear teeth, check valves in said overflow channels preventing a flow against the feed direction.

Abstract: An input signal is received by a level shift circuit to generate a plurality of level-shifted output signals which have different shift amounts to each other. A switch circuit, selectively outputs the level-shifted output signals in response to a logic level of the input signal. The switch circuit selects a signal having a higher potential from the level-shifted output signals when the logic level of the input signal indicates a first level, and selects a signal having a lower potential from the level-shifted output signals when the logic level of the input signals indicates a second level.

Abstract: An admixture for cement compositions is prepared by calcining at 630.degree. to 870.degree. C. at least one substance selected from the group consisting of natural kaolin, halloysite and synthetic kaolin, effecting classification so that amorphous portions of alumina/silica having a mixing ratio of 0.5 to 1.3 form main components, with all particles having diameters up to 8 .mu.m and an average diameter of 0.5 to 2 .mu.m, and a specific gravity ranging from 2.45 to 2.55. This admixture is used to produce a cement composition such as mortar or concrete, which realizes excellent fluidity to promote workability, and a high strength structure.

Abstract: A glue for sealing the side seams of smokable articles contains 5 to 40 percent by weight dry substance pectin in an aqueous dispersion; to produce this glue the aqueous dispersion of the pectin is prepared by charging the pectin portion-wise into heated, demineralized water, stirring the corresponding mixture and executing a chain decomposition of the pectin.

Abstract: There are disclosed a DNA-immobilized microsphere comprising DNA chains having base sequences which bind a specific protein specifically, and a carrier having a particle size of not more than 50 .mu.m and not less than 0.01 .mu.m which does not adsorb any protein, said carrier and said DNA chains being bound to each other by a chemical bond, and a process for purifying a protein using said microsphere.

Abstract: A resilient terminal with a buckling prevention mechanism has a pair of electric contact portions that are interconnected through a flexible joint portion. The pair of contact portions are provided with abutment portions that are disposed opposite to each other with a small gap therebetween. When there is a misalignment between the mating terminals or when an excessive insertion force is applied, the flexible joint portion of the terminal deflects to allow the male terminal to be inserted therein. The flexible joint portion, however, is protected against buckling because an excess bending of the joint portion is blocked by the abutment portions abutting against each other. At the same time, one of the abutment portions slides on the other, correcting the terminal misalignment and ensuring reliable terminal engagement.

Abstract: A colored precipitated calcium carbonate having a strong color fastness in water is produced by preparing an aqueous slurry containing calcium hydroxide and a water-soluble dye, for example, a direct dye, introducing a carbon dioxide-containing gas into the aqueous slurry, and collecting the resultant colored precipitated calcium carbonate from the aqueous slurry at a pH of 8.2 or more thereof.

Abstract: A tying band cluster consists of a plurality of tying bands connected in series, end to end, in longitudinal direction. Each of the tying bands has a head portion, a projecting piece formed at one end of the head portion, and a major portion of a band body formed at the other end of the head portion. When a tying band is formed, the projecting piece of the current tying band is fused with the free end of the major portion of the previous tying band. Because the major portion of the previous tying band is left in the molding dies when the next tying band is formed, the major portion of the previous tying band is kept heated and can therefore be fused completely with the projecting piece of the tying band currently being formed. This ensures a solid connection between the tying bands.
