Title: Hot water making machine and mechanism thereof
Inventor: MURAKAMI HIROAKI
IPC: F24J3/00
Filed: 1985-10-28
Abstract: PURPOSE:To reduce cost by a method wherein, through utilization of energy of flowing water of a river, the temperature of oil is increased and forms a heat source, and through interlocking of the action of a low pressure, water is changed into steam to blow it in a water tank to manufacture hot water. CONSTITUTION:With a device installed in flowing water, flow water flows in from a screen 1 and flows through a bell-mouth 2 and after it rotates a water turbine 3, it is discharged through an outlet 5 to the outside. In this case, a streamline type runner 4 is rotated to rotate a main gear in a gear box 8. The main gear rotates a vane pump 11 at a high speed to generate an oil pressure, and energy is stored in an oil tank 29 through a cylinder 33. Through the use of the pressure, a hydraulic cylinder 5 of a hot water generator is driven. In a steam producing chamber 7, a low pressure piston 9 is driven by the hydraulic cylinder 5 to manufacture steam. In a high temperature hot water tank 25, the heat dissipation part of a Freon gas pipe 16 running from a high temperature oil tank 17 heats water to produce hot water. This constitution enables manufacture of hot water only by energy of flowing water of a river, and enables reduction of a cost.

Title: Start controller of reciprocating machine driving motor
Inventor: HAMAGUCHI MARIO
IPC: H02P1/40
Filed: 1983-12-22
Abstract: PURPOSE:To reduce the output current capacity of an inverter by temporarily stopping the start when the rotating direction that a starting torque increase is detected, switching to a rotating direction that the torque decreases, and restarting. CONSTITUTION:An inverter 5 is energized to start a compressor to generate an AC output for driving a compressor in a normal rotating direction. When the angular position of the crankshaft of the compressor at the starting time is at theta1, the rotating direction is to decrease the torque, and it can be readily driven. On the other hand, when the angular position of the crankshaft at starting time is at theta2, it is hardly started, and a large starting current flows. When an overcurrent is detected by a current detector 10, a controller 7 immediately stops the output of the inverter 5. After it is reversely rotated for the prescribed time, the crankshaft is then restarted in a reverse direction.
