Filed: 1991-07-05
Abstract: PURPOSE:To attain a focusing operation for an object at a near distance by judging that the object is present at the near distance, and moving a zoom lens to a wide angle side by using the low-pass frequency components of a luminance signal. CONSTITUTION:When a focal point is not detected at the zoom position at a telephoto side, a control circuit 5 switches a switch 403 to an LPF 402 side, and extracts the low-pass frequency components of a luminance signal Y. At the time of judging that the object is present at the near distance, the circuit 5 switches the switch 403 in order to obtain a focus evaluation value (y), and drives a zoom motor 8 by a motor driver 7 in order to automatically move a variator 102 to the wide angle side. At that time, when a master lens 104 is positioned at an end point at the near distance side, it necessarily passes the focal point, so that the focal point can be detected by monitoring the evaluation value (y) during a zoom back. Thus, even when the object is changed at the near distance, the focusing operation can be speedily continued without any error.

Abstract: PURPOSE: To reduce scale loss of a steel material and to improve the yield by arranging gas passage providing two heat storage bodies in a heating furnace for the steel material and mutually changing over the one side as the heat storage body with combustion exhaust gas and the other side as a preheating device of non-oxidized gas with the heat storage body. CONSTITUTION: In the case of heating the steel material in the heating furnace, two heat storage bodies A, B are fitted to the heating furnace, and after heating the heat storage body and storing the heat by passing the high temp. exhaust gas having >=1300 deg.C from the heating furnace through the one side of the heat storage body A, this exhaust gas is exhausted into the air as the low temp. exhaust gas. Successively, after preheating mixed gas of H2 gas and N2 gas or reducing gas containing H2 , CO, etc., at the combustible critical temp. or lower through the heat storage body A by changing a changeover valve, the gas is burnt in the heating furnace and the steel material is heated, and the exhaust gas is passed through the heat storage body B and the heat storage body B is heated with the contained heat, and after storing the heat, the exhaust gas is exhausted into the air.  Since the heat of the steel slab is executed with the preheated non-oxidizing high temp. gas, the surface of the steel slab does not develop the scale caused by oxidizing, and it is prevented that the yield is lowered by developing the scale with the heating.
