    • PROBLEM TO BE SOLVED: To provide a method and device in which a strong pile foundation can be formed at low cost and easily without using a long pile or a driving machine to generate a large load. SOLUTION: After a follower 9 inserted into a hole 3 bored in the ground 1 is a little pulled up, hardening agent 8 comprising plural sorts of aggregates agitated and mixed with each other is charged into the hole, the follower 9 is put down, and it is pressed with a vibrator 11. The follower 9 has a ball surface of a proper radius at a tip of a columnar main body, and pressure applied from the tip of the follower 9 to the hardening agent 8 is dispersed in four directions as well as in a vertical direction to press the hardening agent 8 in the four directions. Charging of the hardening agent 8 and pressurizing with the vibrator 11 are repeated, so the inside of the hole 3 is tightened to an upper part with the hardening agent 8. After a specified time, the hardening agent 8 is hardened by hydration reaction with water content in the ground, and a pile foundation integrated with the ground 1 is formed from upper parts to lower parts. The hardening agent 8 is carried by a shovel including an agitator to be charged into the hole 3.

    • PROBLEM TO BE SOLVED: To provide an engine which is reduced in energy loss and makes the most of advantages of a reciprocating engine and a rotary engine.
      SOLUTION: A piston 1 is lifted or lowered by turning a cylinder block 2 clockwise and turning a crankshaft 3 anticlockwise, respectively, by 90 degrees. The suction, compression, combustion and exhaust operations can be carried out successively while the positions for suction, compression, combustion and exhaust are changed. Since suction and exhaust valves are not required, it is possible to reduce the energy loss.

    • PURPOSE:To eliminate friction loss and obtain an improved thermal efficiency in an internal combustion engine by a construction wherein a pair of pistons are oppositely mounted in a combustion cylinder and both pistons are capable of effecting reciprocating motion and rotation at the same time. CONSTITUTION:A pair of pistons 10 are mounted in a combustion cylinder 1 so that they can reciprocate freely opposite to each other along piston grooves formed in the inner wall of the cylinder 1. Air supply holes 14, air supply grooves 5 and scavenging air grooves 12 are arranged to open in a combustion chamber 2 defined between the pistons 10 at synmetrical positions at the right and left ends and top and bottom thereof. Further, an exhaust gas groove 13 is arranged to open in the combustion chamber 2 and recovery of motive power is made in the process wherein the exhaust gas produced by combustion is discharged from an exhaust gas passage (not shown) which is perforated in a cooling fin 7 through guide blades 30 of a fixed outer cylinder 35 and exhaust gas rings 31. Mounted on the outer periphery of the combustion chamber 1 are left and right bent groove cylinders 16 each having a bent groove 17. The rolling part (not shown) mounted on each piston 10 is engaged with the bent groove 17 so that the piston 10 may be rotated when it is slidably moved in the axial direction.
