Title: Louver control device for continuous rolling mill
Inventor: SEKI YOSHIRO
IPC: B21B37/00
Filed: 1986-05-29
Abstract: PURPOSE:To inexpensively realize the control system of good stability and quick responsivemess by setting the integral and proportional gains while under rolling with the linear interpolation by using the speed reference of a main motor or the experienced value based on the prestoraged gain data. CONSTITUTION:An optimum gain setting device 23 calculates and stores the gain in the plate passing speed and that in the rolling maximum speed from the rolling information at the gain arithmetic time prior to the stock to be rolled reaching to the continuous rolling mill, for instance at the time when the material detector set up at the upper stream side of the continuous rolling mill detects the stock to be rolled. The setter 23 finds the optimum gain while the stock to be rolled is rolled and by setting it the correction amount DELTAN of the main machine speed target value and louver speed reference DELTANL are decided. The rotary speed of the main motor 5 is corrected so as to follow up those and a tension t1 and louver angle Ptheta are controlled to the target value.

Title: Ic power source controller
Inventor: IWATA HIDETOSHI
IPC: G06F1/24
Filed: 1989-05-19
Abstract: PURPOSE:To surely execute the power-on reset by making an electric discharge loop at the time when a power source supply is cut off. CONSTITUTION:When a control circuit 2 output 'L', a transistor TR Q2 is turned off, and a TR Q1 is turned on, therefore, a power source is supplied to an IC 3. When the circuit 2 outputs 'H', the TR Q1 is turned off, and the TR Q2 is turned on, therefore, a power source supply to the IC 3 is cut off, and charge which remains in a capacity component 4 passes through the TR Q2 and discharged. In this regard, a collector resistance of the TR Q2 is adjusted so that a power supply voltage becomes below Va within the minimum time in which the circuit 2 becomes 'L', and thereafter, becomes 'H'. In such a way, this controller is constituted so that in the case the IC is controlled by the power source of the IC, the power-on reset is always applied, and the IC can be allowed to rise surely. Also, since an electric discharge loop is turned off at the time of supplying the power source, no excessive current is not al lowed to flow, and the effect for practical use is large.

Abstract: PURPOSE:To enable connection of a copper plate and an armature winding without requiring flux by a method wherein the copper plate is previously brazed to a commutator riser. CONSTITUTION:An armature winding 2 having an upper conductor 2a1 and a lower conductor 2a2 is welded to a riser 3 formed of an alloy containing iron and nickel, iron material, etc. using phosphorus copper without the need of flux.
