Title: Production of aluminum nitride powder
Inventor: ICHIKAWA HACHIRO
IPC: C01B21/072
Filed: 1987-03-31
Abstract: PURPOSE:To contrive to reduce cation impurity content in production of aluminum nitride powder by reacting a mixture of alumina and carbon with a N2 gas, by bringing the mixture into contact with a N2-containing inert gas under a compound condition before starting of AlN formation reaction. CONSTITUTION:A mixture of alumina powder and carbon powder is heated in a N2-containing inert gas at >=1,400 deg.C and converted into AlN and CO. In this case, cation impurity in alumina and carbon is also converted into a nitride or carbide and retained in AlN. In order to prevent the conversion, when the mixture is reacted with the N2 gas, before AlN formation reaction is started, a N2 gas-containing inert gas is brought into contact with the mixture at 1,000-1,400 deg.C under <=0.1atm. Consequently, content of the cation impurity in the mixture can be extremely reduced. Therefore AlN powder having extremely low cation impurity content is obtained.

Abstract: PURPOSE:To perform a sharp breaking control by cascading a transistor and a thyristor and using the base end the gate as control terminals. CONSTITUTION:In case that a water level is detected by a control terminal, transistor 4 is conductable and thyristor 5 is ignited when terminals 6a', 6b' and 9a' are beneath the water. Then, both ends of secondary coil 12 of transformer relay 1 are shorted through diode bridge 3, transistor 4 and thyristor 5, and contact 13 is turned on. When the water level is lowered, the base current is reduced to turn off the thyristor. Then, contact 13 of transformer relay 1 is turned off. When three terminals are beneath the water, contact 13 is turned on; and when terminal 9a' is on the water, the contact is turned off. As a result, the circuit can be turned on and off by a sharp hysteresis characteristic.

IPC: B21B1/38
Filed: 1985-04-10
Abstract: PURPOSE:To improve the yield of a product by constituting rolling rolls of large- and small-diameter rolls and rolling metallic plates of which the metallic plate having the smaller elongation rate is disposed on the small-diameter roll side. CONSTITUTION:The upper rolling roll 1 of the upper and lower rolling rolls 1, 2 is made smaller in diameter than the lower rolling roll 2. The rolls 1, 2 are rotated at an equal peripheral speed in the directions opposite from each other. The metallic plate A which has the large elongation rate is disposed on the lower side and the metallic plate B having the smaller elongation rate is disposed on the upper side, then both plates and superposed and rolled. Since the draft of the roll 1 is made larger in this stage, the plate B having the smaller elongation rate on the roll 1 side elongates well. The elongation thereof balances consequently with the elongation of the lower plate A having the larger elongation rate. The irregularity of both plates A, B at the rear end is eliminated by the above-mentioned method, by which the yield of the product is improved.
