IPC: H01C7/00
Filed: 1986-12-27
Abstract: PURPOSE:To suppress the pattern thinning due to side etching by providing patterns for preventing the proceeding of etching in the vicinity of the connecting part with a conductor pattern at the time of forming a thin film resistance pattern by a photoresist and a wet etching process. CONSTITUTION:On an insulating substrate 10 of a silicon substrate, glass, ceramics or the like having a silicon oxide film formed on the surface thereof, a tantalum thin film as a resistance film and NiCr, Pd, Au or metal are continuously grown by a magnetron sputtering. Then the conductive metallic film on the uppermost layer of the substrate is formed into a conductor pattern 2 with a photoresist by an etching process. And on both sides of the resistance pattern in the vicinity of the conductor pattern 2, a photo mask having patterns for preventing the proceeding of etching is formed on the tantalum film, a resist resistance pattern is formed by a photoresist processing, and subsequently the exposed tantalum film is selectively removed by means of a wet etching method with a mixed liquid of hydrofluoric acid, nitric acid and acetic acid. Thereafter, the resist is peeled off and removed, thus forming a tantalum thin film resistor 1. With this, the side etching of the pattern is suppressed, whereby the reduction of the pattern width can be prevented.

IPC: B21B1/04
Filed: 1990-11-15
Abstract: PURPOSE:To stabilize the mill roll support and to surely manage the tension between stands by setting the housing support at the position just below the material pass line freely swingably. CONSTITUTION:The rolling is executed successively with the mill roll 11A, 11B of V mill 29 and the mill roll 31A, 31B of H mill 30.

Because the dead-weight of V mill and the other indefinite element exist actually, the relation between the tensile force F and the reaction force R1 of the load cell is measured actually and made to the data for operation, so the stable detected result can be obtained. Therefore, the management for the tensile force between the stands (the control of the rolling mill) as the countermeasure for preventing cracks on the inner or outer parts of the cast billet can be surely executed.

Filed: 1986-12-24
Abstract: PURPOSE:To attain the operation at a high speed and with low power consumption as a whole by increasing number of automatic zero amplifier stages of voltage comparatros being components of a 1st parallel AD converter more than the number of automatic zero amplifier stages of voltage comparators being components of a 2nd parallel AD conversion section. CONSTITUTION:The number of stages of automatic zero amplifier stages 10 of voltage comparators 3a-3c in the 1st parallel AD conversion section 1 deciding the high-order bit is increased more than the number of stages of automatic zero amplifier stages of voltage comparators 4a-4c in the 2nd parallel AD conversion section 2 deciding the low-order bit. Thus, the 1st parallel AD conversion section 1 is quickened in its operation and the operation margin is increased. Since the input difference voltage of voltage comaparators 3a-3c in the 1st parallel AD conversion section 1 is large, the power consumption is less. Moreover, low power consumption is attained regardless of a minute input difference voltage. Thus, the AD converter with high speed and low power consumption as a whole is obtained.
