Abstract: There is provided a device for applying liquid on a rail capable of minimizing wasteful flowing down of expensive application liquid to suppress the total amount of discharge of the liquid, reducing costs and further suppressing occurrence of environmental contamination, and preventing slippage of a wheel due to excessive liquid application. The device for applying liquid on a rail includes a tank, a liquid discharge pump for receiving supply of application liquid from the tank and performing a liquid discharge operation as a wheel passes, and a liquid application unit for discharging the application liquid onto a rail upon being supplied with the liquid from the liquid discharge pump. The liquid application unit has a nozzle block 40 having a large number of nozzle holes 43 arranged in the upper surface of the nozzle block, and the nozzle block 40 has on its end section a hole-less end section 40a where no nozzle hole is provided.

Abstract: This engine is substantially free from any vibration and noise, small in friction loss, improved in mechanical efficiency to a considerable extent, compact and lightweight, and applicable to a reciprocating piston engine. The engine comprises: curved cylinders each assuming a circular shape in cross section; curved pistons (1, 1a) each fitting and reciprocating within the cylinder; a rotor (2) carrying the pistons (1, 1a) to keep them in balance and to have them be rockable about the center of the rotor (2), wherein the rotor (2) is provided with connecting rods (6, 6a) to impart half a rocking power of the rotor (2) to each of crank shafts (10, 10a) each of which converts the half of the rocking power to a piece of torque on its axis of rotation; a gear mechanism for receiving the pieces of torque to combine them into an output power; and, an output shaft connected with the gear mechanism for receiving and out-putting the output power.
