Abstract: A molded article or water-supply pipe free from causing dot-like projections or small-diameter blisters on the molded article surface when the molded article is brought into contact with chlorine-containing water is obtained from a resin composition containing a polyolefin resin, a pigment and a copolymer resin obtained from a monomer having an .alpha.,.beta.-unsaturated double bond and a dibasic acid having an unsaturated double bond or an anhydride thereof.

Abstract: A strapping machine is disclosed which enables a prolonged life of the driving force supplying means for feeding/tightening a band such as an electric motor to be realized, and which enables maintenance operations such as replacement and adjustment of the parts to be carried out with ease, and whose structure can be rendered simple and inexpensive as a whole, and yet which enables energy saving to be realized. The strapping machine comprising a band feeding/tightening means F adapted to conduct feeding, primary tightening, secondary tightening of a band B to be looped around a periphery of an object to be strapped and the like operation; wherein said band feeding/tightening means F is so constructed as to carry out feeding, primary tightening and secondary tightening of the band B by driving a roller 8 by means of a driving means M2 which is capable of being controlled among rotation, reverse rotation and stopped state.

Abstract: A coated molded article obtained by coating a lacquer containing an organic solvent on a molded article produced from a resin composition comprising 100 parts by weight of one resin selected from the group consisting of an acrylonitrile-butadiene-styrene terpolymer resin, a mixture of said terpolymer with a polyvinyl chloride resin, and an acrylonitrile-ethylene propylene rubber-styrene terpolymer resin, 10 to 50 parts by weight of thermoplastic polyester resin, and 1 to 100 parts by weight of an electrically conductive fiber.

Abstract: A decompressor for an internal combustion engine including a mounting hole in which a decompression valve for opening and closing a pressure relief bore opening into a combustion chamber within a cylinder of the engine, is disposed, and also including a through-hole which is obliquely and rectilinearly formed through a portion of a wall of the cylinder, and through which an outer open end portion of the mounting hole is able to communicate with a scavenging passage of the engine.

Abstract: A fresh water generator includes a primary pump for pumping up water to be treated, a secondary pump for pressure sending, and a filtering device for purifying the water to be treated which is sent from the secondary pump by pressure. The fresh water generator further includes interlocking devices for interlocking clutch means of transmission devices and an operation lever of a three-way valve. The operation lever can be switched to one position from the other position and vice versa. The one position is a position in which the clutch means are actuated, thereby transmitting drive power from an internal combustion engine to the primary pump. The other position is a position in which the clutch means are relaxed, thereby blocking transmission of the drive power to the primary pump.

Abstract: An automatic traveling apparatus comprising a self-propelling car having a self-propelling drive is mounted on a carriage car in such a manner as to be dismountable therefrom. The apparatus also includes a driving-force transmission which, when the self-propelling car is mounted on the carriage car, engages with the self-propelling drive of the self-propelling car to drive the carriage car into traveling.

Abstract: A self-propelled car is placed on a handcart in such a manner that it can freely ride on and ride off of the handcart. The handcart is provided with at least one roller which engages with the driving wheels of the self-propelled car to interrupt the running thereof.

Abstract: A mobile carriage comprises wheels which are respectively rotatably provided through one-way clutches at each end of wheel shafts disposed at the front and rear of the carriage, the wheels at the front of the carriage in the moving direction thereof serving as driving wheels so that the carriage can be driven backwardly and forwardly using a prime mover.

Abstract: A plunger pump including an inlet chamber for forwarding a fluid drawn by suction to a pump chamber via a suction valve, and an outlet chamber for receiving from the pump chamber a fluid pressurized in the pump chamber via a discharge valve. The inlet chamber and outlet chamber are formed in a main body and located radially outwardly of seal packings in close proximity thereto.

Abstract: Particles of spray solution are given with an electrostatic charge by applying voltage of 300 to 800 V thereon as the solution passes through the tip of the spray nozzle of an electrostatic spray dispenser.
