Title: Production of wear resistant material
Inventor: ARATA HIROTO
IPC: C22C37/06
Filed: 1981-09-30
Abstract: PURPOSE:To obtain a superior wear resistant material in which the shapes of carbide are changed and the hardness of matrix is increased by subjecting high Cr cast iron to the special heat treatment which increases C, adds Si, Mo, V, etc. and cools mists at specific cooling rates. CONSTITUTION:High Cr cast iron contg. by %, 3.0-4.0 C, 0.5-2.5 Si, 15.0-30.0 Cr, 1.0-30.0 Mo and V, Nb is heated. While the moisture content in blast is controlled, said cast iron is cooled with mists at 10-100 deg.C/min cooling rate. Here, if the C is below the lower limit, the absolute quantity of barbide is small and wear resistance cannot be assured. If in excess of the upper limit, the car bide of the initial crystal is too much to be maintained. The Si and the Mo improve the hardness of the matrix, and the V improves its toughness. The cooling  rate is required to be in the above-described range in order to allow the carbide  on the surface to be used to deposet in the form of columns as shown. Such high cooling rate cannot be obtained with furnace cooling, air cooling or blast cooling except for extra small-sized products. On the other hand, with water cooling and oil cooling, the cooling rate is so high that retained austenite is formed and hardness decreases considerably; therefore, the mist cooling is employed.

Title: Voltage drop detection circuit
Inventor: TANIGAWA KIYOSHI
IPC: G01R19/165
Filed: 1981-09-30
Abstract: PURPOSE:To prevent abnormal action of an electronic circuit accurately detecting instantaneous voltage drop by allowing quick discharging of an electric charge from a capacitor when voltage drops instantaneously. CONSTITUTION:After the power source ia switched on, an electronic circuit 3 is kept initially or locked before the voltage Vc6 across a capacitor 6 reaches a threshold VTH of a comparator 8. As the voltage Vc6 exceeds the threshold VTH after a given time, the output voltage VCP of the comparator 8 goes to a high level enabling the electronic circuit 3. Assuming that the voltage E of the power source drops instantaneously for some reason, the time constant by a capacitor 11 and a resistance 10 is fixed at a sufficiently large value. This can make the lowering rate dVC11/dt of the voltage VC11 so much smaller than the lowering rate dE/dt of the power source voltage E to keep the voltage VC11 almost constant. Therefore, the drop margin of the power source voltage result in the lowering of the base voltage of a transistor 14 to cut off the transistor 14. With the conducting of a transistor 16, a capacitor 6 is charged to allow the feeding a initial set signal or the like to the electronic circuit 3.
