Title: Buoyancy generating system
Inventor: MIYAGISHI TOSHINOBU
IPC: F03B17/02
Filed: 1982-02-01
Abstract: PURPOSE:To produce power with low cost by floating a rotary member having a floating chip where fluid having low specific gravity is placed on other fluid having high specific gravity then converting the buoyancy of said rotary member into rotary motion or linear motion to drive a generator. CONSTITUTION:A rotary member 2 is comprised of a fixed section 3 and a rotary section 4 where a floating chip 8 is provided at the tip of an arm metal 7 extending radially. An air feed pipe 5 and an air discharge pipe 6 are mounted on the fixed section 3, and when said member 2 is placed in a water tank and the air is fed through said pipe 5, the floating chip 8 conducting to the air feed port of the air feed pipe 5 will inflate while a floating chip 8 conducting to the air discharge port of the air discharge pipe 6 will shrink. Since the rotary member 2 will half inflate while half shrink, it causes the differential buoyance to produce the rotary force which is used to drive a generator thus to produce power.

Title: Liquid fuel burner
Inventor: KAWAMOTO TAKAO
IPC: F23D11/44
Filed: 1983-02-01
Abstract: PURPOSE:To prevent re-condensation of an evaporated gas at the burner part at the time of ignition using only an electric heater and utilize the combustion gas absorbed by the burner at the time of continuous combustion for evaporating heat to greatly reduce the quantity of power consumed, by efficiently carrying out a heat transfer between the evaporator and the burner. CONSTITUTION:In the titled liquid fuel evaporating burner, a heat transfer property between the evaporator 1 and the burner 12 is adjusted by inclusions such as a heat insulator 17 and the like. A temperature gradient coincident with the operational state of the liquid fuel burner is generated between the evaporator 1 and the burner 12. Since the temperature gradient coincident with the operational state is generated, a part of heat generated by the electric heater 2 moves from the evaporator 1 to the burner at the time of preheating within the burner, and the combustion heat absorbed by the burner can be moved to the evaporator 1 at the time of continuous combustion.
