Title: Oxidation preventing method of tank annealing process
Inventor: KAIHOU KATSUHARU
IPC: C21D1/74
Filed: 1978-09-18
Abstract: PURPOSE:To prevent oxidation due to intrusion of external air when lowering the temperature, by discharging the combustion gas in the tank by substituting with inert gas before and after stopping of annealing and heating to lower the temperature of and shrink the tank. CONSTITUTION:The gas supplied from a gas pipe 6 is burned together with the external air intruded from a manhole duct 7 by a burner 5 provided in the lower part of a spherical shell 2. The combustion gas circulates almost completely in the spherical shell 2 as indicated by arrow A, heating and annealing the spherical shell 2 to the specified temperature, e.g. about 600 deg.C, and the gas is exhausted to the atmosphere from an upper manhole 8 sequentially by the quantity corresponding to the supplied gas capacity. At the end of specified annealing, simultaneously with extinction of the burner 5, a valve 11 of the duct 7 is closed, and a valve 10 of N2 gas supply pipe 9 is opened. The internal combustion residual gas P1 is exhausted properly outside of the system from the manhole 8, and the inside of the spherical shell 2 is gradually substituted with N2 gas P2, so that oxidation of the spherical shell 2 due to high temperature never occurs. When the spherical shell 2 is cooled to ordinary temperature, the filling N2 gas is naturally substituted with external air, and the interior surface of the spherical shell 2 is painted.

Title: Method and apparatus for twin roll type continuous strip casting
Inventor: ARAI TAKASHI
IPC: B22D11/06
Filed: 1992-05-06
Abstract: PURPOSE:To prevent a generation of cast strip breakage due to hot band and a thickness variation of cast strip by detecting a reaction force applied on roll support part and inputting a line contact pressure per roll width to a rolling force control apparatus through a limiter to control under a specified upper limit. CONSTITUTION:When the strip 13 is continuously cast by the twin roll strip continuous casting apparatus which is cooled inside and provided with a pair of rolls 2, 3 rotary driven opposite each other at the same speed, the reaction force applied on the bearings 6, 7 to support the rolls 2, 3 is detected. The specified value P of reaction force, which divides a sum of the detected reaction forces by the roll diameter, is set to 1-25kg/mm and also the specified upper limit P+P for the specified value P is set, among detected values P, the detected value P of reaction force exceeding the upper prescribed value P+P is inputted to the control apparatus 16 through the limiter circuit of proportional control system 17 as set the specified upper limit P+P. Thus, it slows the actuation of rolling force control and decreases a depth of constricted part in the variation characteristic of roll gap.

Title: Production of modular semiconductor device
Inventor: OKUTOMI ISAO
IPC: H01L25/18
Filed: 1999-04-21
Abstract: PROBLEM TO BE SOLVED: To prevent thermal deformation during soldering work without sacrifice of cooling efficiency of a semiconductor element by securing the periphery of a thermal conductor to a thermal conductor securing jig having thickness equal to or thicker than that of a thermal conductor base and then soldering the thermal conductor base. SOLUTION: When soldering is carried out, periphery part of a thermal conductor base 7 is secured rigidly to a thermal conductor securing jig 10a by means of a bolt 9. In order to suppress its own thermal deformation, the thermal conductor securing jig 10a has thickness at least 1.5 times as thick as the thermal conductor base 7. Since bending rigidity of plate shape is proportional to the square of plate thickness, bending rigidity of the thermal conductor securing jig 10a at least doubles that of the thermal conductor base 7 when the thermal conductor securing jig 10a has thickness in the range of 1.5-2.5 times that of the thermal conductor base 7, and thereby deformation of the thermal conductor base 7 can be absorbed by the thermal conductor securing jig 10a.
