Abstract: The rotary piston type internal combustion engine (E1) comprises an output shaft (1), a rotor (2), a housing (4), an annular operation chamber (5) formed by the rotor and housing on at least one side of the rotor in the axial direction of the output shaft for constituting an intake operation chamber, a compression operation chamber, a combustion operation chamber, and an exhaust operation chamber, a pressuring/pressured member (6) provided to the rotor for partitioning the annular operation chamber, two operation chamber partitions (7, 8) provided to the housing for partitioning the annular operation chamber, biasing mechanisms for biasing the operation chamber partitions toward their respective advanced positions, an intake port (11), an exhaust port (12), and a fuel injector (14), wherein the pressuring/pressured member (6) is constituted by an arc-shaped partition having first and second inclined surfaces and the operation chamber partitions (7, 8) are each constituted by a reciprocating partition reciproc

Abstract: A binder fitting 1 has a horizontal base plate 2; rod members 3 vertically fixed on the base plate 2; male screws 8 formed in portions of the peripheral surface of each rod member 3; a press member 4, which has guide holes where the rod members 3 are inserted to be slidable, respectively, and a press surface 10 that presses an object to be filed P, and which is vertically movable in parallel due to a guiding effect of the rod members 3 and the guide holes while angles formed with the press surface 10 and the rod members 3 are maintained at right angles, when pressing the object to be filed P; and operational nuts 5, which are screwed together with the screws 8 of the rod members 3, respectively, and which can press and drive the press member 4 toward the base plate 2.
