Title: Weight balance controller
Inventor: HIRATA TATSUYA
IPC: B23B47/26
Filed: 1984-08-07
Abstract: PURPOSE:To balance weight without causing a shock, through a weight balance controller for a machine tool, by detecting the torsion of a feed screw caused by the bearing of a workpiece, and by determining the difference between a detection signal for the torsion and a standard weight signal to regulate oil pressure for a cylinder. CONSTITUTION:When a workpiece in a balanced weight state is replaced with a heavier workpiece W2 as servo operation is kept, a feed screw 54 undergoes torsion because of the weight increase with the workpiece W2. The torsion is detected by a strain gauge 60, the output signal from which is applied to a comparator 32 to determine the difference between the output signal and a standard weight signal 30. The difference is applied to an oil pressure switch 36, which acts to operate a pressure reduction valve 40 on the basis of the difference to apply oil pressure from a hydraulic pump 46 to a cylinder 48 to augment the workpiece bearing power of a table 52. Weight is thus balanced without causing a shock.

Title: Solar-heat water heater utilizing wind force
Inventor: MATSUMOTO RIYOUJI
IPC: F24S90/00
Filed: 1981-10-15
Abstract: PURPOSE:To enhance the heat-exchanging efficiency of a solar-heat water heater, by forcibly circulating hot water by utilizing a wind force. CONSTITUTION:When a wind-driven rotary part 5 is rotated by the wind force, the rotation is transmitted to a circulation-accelerating part 4 by a rotation- transmitting part 6, water 2 introduced into a solar heat collector 1 through a lower port 7 of a hot water storing tank 3 and heated in the collector 1 is sucked out through an upper port 8, and circulation is accelerated. Since the circulation of hot water 2 is thus accelerated, not only natural convection occurs but a forced circulating action is obtained, so that the heat-exchanging efficiency of the collector 1 can be enhanced. In addition, since hot water is sufficiently stirred, fear of breaking accidents of the solar heat water heater due to freezing is reduced. The operation of the circulation-accelerating part 4 can be controlled by controlling the rotation-transmitting part 6 by a temperature sensor 10. The forced circulating action can be appropriately stopped by providing a detachable clutch in the rotation-transmitting part 6.
