Abstract: A robot operation apparatus includes touch panel, touch operation detecting unit, action command generating unit, and selection operation detecting unit. The action command generating unit is capable of performing an operation determining process and an action command generating process. The operation determining process is a process for determining a drive axis or an action mode of a robot to be operated based on the selection operation detected by the selection operation detecting unit, and when a touch operation detected by the touch operation detecting unit is a drag operation, determining a movement amount of the drag operation. The action command generating process is a process for determining a movement amount of the robot based on the movement amount determined by in the operation determining process, and generating an action command for moving the robot at the drive axis or in the action mode to be operated by the movement amount.

Abstract: A shot pump including a cylinder standing upright and an inlet having a check valve which allows a paste-like transferred substance to only flow into the cylinder therethrough. The shot pump also includes an outlet having a check valve which allows the transferred substance to only flow out of the cylinder therethrough. Additionally, a piston is configured to vertically reciprocate in the cylinder, causing the transferred substance to be sucked from the inlet and then to be discharged from the outlet. The ratio of a clearance between a side face of the piston and an inner side face of the cylinder to an outside diameter of the piston is 1/50 to ½. The transferred substance is sucked from the inlet, is then caused to pass through the clearance between the side face of the piston and the inner side face of the cylinder, and is discharged from the outlet.

Abstract: Provided is a shot pump (100) including a cylinder (101), a piston (102), an inlet (103) and an outlet (104). The inlet (103) is provided on the side of the cylinder (101) facing a tip end of the piston (102) while the outlet (104) is provided on the side of the cylinder (101) at a root of the piston (102). The clearance (?) is provided between outer periphery (102s) of the piston (102) and inner periphery (101s) of the cylinder (101), which clearance has a width at a ratio of 1/50 to 2 to the outside diameter of the piston (102). In addition, the piston (102) reciprocates between the two end portions of the cylinder (101), so that the substance to be transferred is sucked from the inlet (103), is then caused to pass through the clearance (?) between the outer periphery (102s) of the piston (102) and the inner periphery (101s) of the cylinder (101), and is consequently discharged from the outlet (104).

Abstract: A moisture-curing urethane adhesive composition of a urethane prepolymer resulting from the reaction of a mixture of a polyether diol and a polyether triol with a diisocyanate compound, and a polyurethane compound resulting from the reaction of a mixture of a polyester polyol and a polypropyleneether polyol with a hexamethylene diisocyanate compound with addition of a monoalcohol. A modified moisture-curing urethane adhesive composition of a urethane prepolymer resulting from the reaction of a mixture of a polyether diol and a polyether triol with a diisocyanate compound, a first polyurethane compound resulting from the reaction of a copolymeric polyol consisting of propylene oxide and .epsilon.-caprolactone with a hexamethylene diisocyanate compound with addition of a monoalcohol, and a second polyurethane compound resulting from the reaction of a polyester polyol with a hexamethylene diisocyanate compound with addition of a monoalcohol.

Abstract: A UV-curable resin composition, which comprises blending urethane acrylate with tris(2-acryloxyethyl)isocyanurate, or with tris(2-acryloxyethyl)isocyanurate and with diacrylate, which composition has a low viscosity and a good drawing workability before curing and cures rapidly by ultraviolet radiation to give cured products having a high elastic modulus, a high elongation and a low water-absorption.

Abstract: A tension tester in which a specimen marked with at least one measuring marking whose optical characteristic is different from that of the specimen's ground color is held by chucks at the ends and subjected to a tensile load by moving one of the chucks; in which, while the specimen is being stretched, the marking is scanned by a scanner to detect a positional change of the marking in the tensile direction; and in which electric signals which are produced due to the difference in the optical characteristic between the marking and the specimen's ground color are processed to determine the tensile characteristic of the specimen.

Abstract: An ultraviolet-curing resin composition comprising an acrylic oligomer, tris(2-hydroxyethyl)isocyanurate triacrylate, a reactive diluent and a photopolymerization initiator, wherein the acrylic oligomer is a urethane obtained from diphenylmethane diisocyanate, a polytetramethylene glycol having a molecular weight of 650 to 1,300 and a monoacrylate having a hydroxy group, the amount of tris(2-hydroxyethyl)isocyanurate triacrylate is 1 to 100 parts by weight for 100 parts by weight of the urethane acrylate, and the reactive diluent is an acrylic monomer. A mixture of tris(2-hydroxyethyl)isocyanurate triacrylate and a terminal diacrylate having a cycloacetal group may be used in place of tris(2-hydroxyethyl)isocyanurate triacrylate. The compositions are useful as secondary cladding materials and buffer materials in optical fiber units.

Abstract: A slip-on type pipe joint including a socket, a spigot and an annular rubber packing disposed on the inner periphery of the socket at an axially intermediate portion thereof and compressible by the outer periphery of the spigot against the inner periphery of the socket to seal the clearance between the socket and the spigot with its restoring force. The joint further comprises an engaging member detachably attached to the inner periphery of the socket at its open end and radially inwardly projecting from the periphery, a protrusion formed on the outer periphery of the spigot and positioned between the packing and the engaging member, and a split lock ring disposed between the protrusion and the engaging member and fitting around the spigot with a diametrically contractive force. The lock ring is engageable with the engaging member and with the protrusion to prevent the spigot from slipping off the socket.

Abstract: There is provided a tubular connector or the like comprising a socket like means and an annular elastic sealing member to be fitted into the socket in pressing contact with the inner peripheral surface thereof. To assist in the assembly of the sealing member internally of said socket the socket and sealing member is each provided with a plurality of marks spaced apart circumferentially thereof in corresponding relation to the other. The sealing member is fitted into the socket by inserting the sealing member into the socket with the marks on the sealing member set to the corresponding marks on the socket and pressing any slack portions or depressed portions of the member against the socket radially inwardly peripheral surface, whereby the sealing member is secured in uniform pressing contact with the said socket inner surface over the entire outer periphery of the sealing member.

Abstract: A method of making a mold by the use of sand is started by filling a mass of sand in a mold jacket which is in turn rammed to provide a block of sand. The sand block thus formed is excavated by a cutting device to form a mold cavity. The cutting device is guided by a profiling machine in accordance with a predetermined program which describes the shape of an ultimately desired casting to be manufactured by the use of the sand mold.
