Title: Ni alloy short fiber and its production
Inventor: SATO SHUN
IPC: C22C19/03
Filed: 1986-06-20
Abstract: PURPOSE:To provide Ni alloy short fibers having a shape and characteristics adequate as a raw material for catalysts and an electrode material of an Ni-Cd battery by incorporating a semimetal such as B, P or C as a side component at a prescribed ratio into Ni as a main component. CONSTITUTION:The objective Ni alloy short fibers are obtd. by incorporating the semimetal consisting of B, P, C, Si or Ge as the side component at 0 or over - 6at% into the Ni as the main component. The size of the above- mentioned short fibers ranges 0.1-1.0mm width, 0.01-0.3mm thickness and 2-100mm length. The production of the short fibers is executed by dropping the molten Ni alloy in a crucible 3 heated by a heating part 2 from a perforated nozzle 4 at the base of the crucible onto a cooling substrate consisting of a grooved roll and quickly cooling the same. The depth of the V-grooves of the grooved roll is 0.2-5mm and the angles alpha, beta of the side faces of the V-grooves with the outside peripheral face of the roll are respectively in alpha: 30-90 deg. and beta; 20-90 deg. ranges.

Title: Cooling water circulaion for converter exhaustion gas
Inventor: HIRAO MOTOAKI
IPC: F27D17/00
Filed: 1977-12-01
Abstract: PURPOSE:In a water circulating system for cooling converter-exhaust-gas, a tank installation space is reduced by providing the tank with a flexible diaphragm or sliding-piston-type partition which is freely movable so as to provide volume-changeable, hot-and cold-water reservoir. CONSTITUTION:A tank 11 is equipped with high-15 and low-14 temperature reservoirs for hot-water 15 and cold-water 14 respectively. The hot-water 15 is supplied from a cooler 1 for converter-exhaust-gas and the cold water 14 comes from a heat-exchanger 5 which cools the hot water. The reservoirs 15 and 14 are separated by a partition 13 having a flexble diaphragm 12 or a sliding-piston-type partition 13 having a sliding surface at its periphery. When a converter is in operation, the hot water is supplied from the exhaust-gas-cooler 1 and charged in the high- temperature reservoir 15, then discharged to be cooled by the heat-exchanger 5 and charged in the low-temperature reservoir 14 to be circulated into the gas cooler 1. When the converter is at rest, the gas cooler 1 sends cold water through a branch pipe 8 into the low-temperature reservoir 14. Since the total amount of the hot-and cold water is substantially constant, a single tank can accomodate both waters by using automatic partition motion 13, resulting in the reduction of the tank installation space by half.

The arithmetic device 19 decides an operation time period according to the number of times detected by the comparator 18. A controller 15 controls a motor 2 and a heater 7, according to control signals transmitted from the microcomputer 17. When the volume of items to be dried is large, the number of times of falls in the resistance value between the electrodes 8 below the set value within a specified time period increases, and when the volume of the items is small, said number of times decreases. Therefore, the volume of the items to be dried is detected, according to the number of times of falls in the resistance value between the electrodes 8 below the set value within a specified time, and a delay time period of operation is decided.
