Title: Air introducing type rocket
Inventor: YAMAMOTO YOICHI
IPC: B64G1/00
Filed: 1990-01-25
Abstract: PURPOSE:To permit the spin of a rocket in flying and stabilize the flying in the direction of the axis of the machine by arranging an outer cylinder forming a secondary combustion chamber on the periphery of an injection nozzle and installing a spinning means for spinning a rocket in the secondary combustion chamber. CONSTITUTION:When the propellant in a primary combustion chamber 19 is ignited, the combustion gas is jetted into a secondary combustion chamber through an injection nozzle 12 from the primary combustion chamber. At the same time, air is introduced into the secondary combustion chamber from the front edge part of an outer cylinder 13, and the air and the combustion gas are violently mixed and combusted in the secondary combustion chamber, and jetted from the secondary combustion chamber, and a prescribed propulsion force is obtained. Since, in this case, a rocket is spun by the injection nozzle 12 installed in the secondary combustion chamber, the flying in the direction of axis of the machine is stabilized, and the air and the combustion gas flow in spiral form in the outer cylinder 13, and the mixing efficiency in the secondary combustion chamber 20 is improved. Accordingly, even if the total length of the secondary combustion chamber, i.e., the total length of the outer cylinder is shortened, the mixing and combustion can be carried out satisfactorily.

Filed: 1995-02-06
Abstract: PURPOSE: To inspect even deformable piping varied in its pipe diameter with high accuracy by always bringing a probe into contact with the inner surface of the piping by pressing the front and rear parts of a probe holder outward with springs. CONSTITUTION: A piping inspecting probe is inserted in piping 101 having a part 102 varied in its pipe diameter and a probe head 6 is rotated while moving in the axial direction of the piping to perform inspection. Because the probe holder 2 (2a, 2b) is pressed outward at the front and rear parts thereof by compression coil springs 3 (3a, 3b), the probe 1 (1a, 1b) of the holder 2 is always brought into contact with the inner surface of the piping 101 to slide. When the outer surface of the holder 2 is inclined along the inner surface of the piping especially at the part 102, a shaking part 4 is rotated at a pin connection part and the pressing forces of the front and rear springs 3 become almost equal. Therefore, the outer surface of the holder 2 always comes into contact with the inner surface of the piping and the front and rear ends of the holder are uniformly pressed.  By this constitution, the probe 1 always comes into contact with even deformable piping changed in its pipe diameter to inspect the piping with high accuracy.

Abstract: PURPOSE:To improve plating quality with decreased use of an atmosphere gas by circulating and supplying the atmosphere gas from which Zn vapor is removed by solidification to the spacing between two sealing mechanisms provided in the upper part of a down chute in which a steel strip subjected to a heat treatment is passed in the stage of plating the steel strip with a molten Zn-Al alloy. CONSTITUTION:The steel strip 6 from a heat treatment furnace 3 is passed through the inside of the molten Zn-Al alloy in a cell 5 by the down chute 4 and a snout 9 by which the steel strip is subjected to hot dipping. The atmosphere gas of H2+N2 is passed in the down chute 4 in order to prevent the oxidation of the steel strip 6. Since the Zn vapor exists in the atmosphere gas, the Zn vapor is cooled to solidify and is removed in a Zn solidifying chamber 6. The atmosphere gas is heated in a heater 18 in the state of contg. no Zn and is pressurized by a pressurizing device 17, then the gas is supplied between two sealing mechanism 13 and 13 provided in the upper part of the down chute 4. The atmosphere gas contg. the Zn vapor is put into the heat treatment chamber 3 by a shielding layer 40 consisting of the high- pressure atmosphere gas. The atmosphere gas enters the Zn-Al alloy plating bath and forms the plating surface having high quality without sticking zinc white on the surface. Since the atmosphere gas is cyclically used, the cost thereof is reduced.
