Title: Rotational speed control device for inverter type engine generator
Inventor: OGURA KAZUHIKO
IPC: H02P9/04
Filed: 1990-10-13
Abstract: PURPOSE:To start up powerfully an engine even with a generator under load by installing a means which shifts up an objective rotational speed to a value within a high-speed rotation range by sensing the engine in its starting state. CONSTITUTION:The objective rotational speed of an engine 1 is calculated by a rotational-speed arithmetic means 7 on the basis of detection of the electric output of a generator 2 by an output detector 6. A rotational speed regulating device 9 of the engine 1 is manipulated to a position corresponding to the objective rotational speed by a rotational speed regulating actuator 8. A starting-state sensing means 11 attached to the engine 1 then shifts up the objective rotational speed outputted from the rotational-speed arithmetic means 7 to a value within a high speed rotation range on the basis of sensing the starting state of the engine l when the engine is in this state. Accordingly the rotational speed regulating device 9 is manipulated to a position within the high speed rotation range. Torque in the engine 1 is thus increased, so that the rotational speed rises by overcoming the load, and the engine can make start-up powerfully without any engine stall.

Title: Ice heat accumulating device
Inventor: KIMURA HIROSHI
IPC: F28D20/02
Filed: 1989-10-20
Abstract: PURPOSE:To improve efficiency during cold accumulation, to increase a cold accumulation amount, and to reduce a cost by providing a heat accumulating tank to contain water serving as a heat accumulating material and an organic material being insoluble in water and serving as a heat exchange medium and not chemically reacting with water and having specific gravity lower than that of the water, a freezing cycle, a circulating device, and a net body containing a discharge port therein. CONSTITUTION:When a compressor 10 and a circulating pump 25 are run by means of a midnight power, kerosene 41 is sucked through a suction port 44-1 and flows to a cooler 13. In which case, the kerosene 41 cooled through operation of a freezing cycle 1 is discharged in water 21 through a discharge port 42-1. Since the kerosene has specific gravity lower than that of the water 40, the kerosene 41 is raised to the upper part of a heat accumulating tank 20 as it is heat-exchanged with the water 40. The kerosene is sucked through the suction port 44-1 again. Continuance of the operation causes lowering of the temperatures of the kerosene 41 and the water 40. When the temperature of the water 40 is decreased to 0 deg.C and the temperature of the kerosene discharged through the discharge port 42-1 is decreased to -5 deg.C or lower, small pieces of ice are started to produce in the water 21. Thus, even when the number of the ice pieces is increased, the ice pieces are caught by a wire net 50, and the kerosene 40 can flow to continue heat accumulating operation.
