Abstract: PROBLEM TO BE SOLVED: To stably obtain an excellent magnetic characteristic by regulating an operational condition at the first time of cold-rolling after intermediate annealing. SOLUTION: The first time of cold-rolling after intermediate annealing is executed with a tandem rolling-mill. In such a case, a steel sheet temp. at outlet side of the last pass in the tandem rolling is made to 100-300 deg.C, and statical ageing is promoted by coiling and holding in this temp. range and, thereafter, the cold-rolling is executed to restrain the biting steel sheet temp. to <=300 deg.C while holding the excellent magnetic characteristic, and the attaching by burning of rolling oil to the steel sheet as a problem at the time of rolling in high temp. can be eliminated.  As for the coiling and holding temp., though such an excellent product as to exceed 1.9T magnetic flux density is obtd. in a short time and enough magnetic characteristic can be obtained only by allowing to stand in the atmosphere after the coiling, it is desirable further to keep the product in the coiling temp. range of 100-300 deg.C for >=20min.

Filed: 1988-08-01
Abstract: PURPOSE:To detect current flowing in a source for main current, with small current and low power consumption, by constituting the area of a source for current detection so as to be a specified fraction of the area of a source for main current. CONSTITUTION:A plurality of surface gate type electrostatic induction transistors are formed on a substrate 20. These semiconductor elements are divided by m:n; sources of (m) elements are connected with an electrode as a source S for main current; sources of (n) elements are connected with an electrode as a source SS for current detection. Drains and gates are commonly connected for all elements, and connected with electrodes as a drain D and a gate G, respectively. By making (m) large as compared with (n) in this constitution, a small part of drain current can be made to branch and flow into a resistor connected with the source SS, and an over-current protecting circuit can be constituted. Hence, the total current flowing through an electrostatic induction transistors can be detected by a very small current, and problems such as heat generation are not encountered because of low power consumption.
