Filed: 1990-10-16
Abstract: PURPOSE:To produce a steel plate for structural use excellent in toughness at low temp. and having high Young's modulus with superior productivity at a low cost by applying respectively specified hot rolling and cooling to a slab of structural steel and subjecting the resulting hot rolled plate to specific rolling in the two phase region and then to specific tempering treatment. CONSTITUTION:A slab of structural steel with a temp. between the Ar3 point and 1250 deg.C is hot-rolled at a temp. between the recrystallization finishing temp. and the Ar3 point at >=20% reduction of area and cooled, without delay, at >=5 deg.C/sec cooling rate. Subsequently, the resulting hot rolled plate is subjected to rolling in the two phase region at a temp. below the Ar3 point at >=50% reduction of area. After subjected, if necessary, to controlled cooling down to <=600 deg.C at >=5 deg.C/sec cooling rate, the steel plate is subjected to tempering treatment at <=700 deg.C for 5-30min. By this method, the steel plate for structural use excellent in toughness at low temp. and improved in Young's modulus by about 15% can be obtained.

Filed: 1989-10-27
Abstract: PURPOSE:To accurately and stably measure an electrostatic capacity by providing a shielding electrode between a piezoelectric element electrode and an electrostatic capacity measuring electrode. CONSTITUTION:The electrostatic capacity between a diaphragm 9 and an electrode 5 is detected by a detecting circuit 10 and is converted to a corresponding value by a measuring circuit 11, and a control circuit 12 compares the value with a reference value; and when it is smaller than the reference value, a piezoelectric element driving circuit 13 is controlled to increase the electrostatic capacity. That is, a signal to expand a piezoelectric element 1 is outputted. When it is larger than the reference value, a signal to reduce the element 1 is outputted. The driving voltage of the element 11 is proportional to the input signal of the circuit 13. That is, the output of the control circuit 12 is converted to pressure data by a converting circuit 14 and is displayed by a display circuit to obtain a pressure value. Thus, the driving voltage of the element 1 is always varied in accordance with the pressure. Therefore, a shield 2 and an insulating material 8 are provided and the potential of the shield 2 is insulated from electrodes 3 and 4 of the element 1 and is equalized to that of an electrode 5 to prevent the measurement error due to the variance of the driving voltage of the element 1.
