Inventor: UGI TAKUMI
IPC: C23G1/19
Filed: 1986-12-19
Abstract: PURPOSE:To improve the rust resistance of a bright-annealed ferritic stainless steel, by immersing the steel in an aq. soln. contg. a specified amt. of sodium silicate at a proper temp. for a proper time. CONSTITUTION:A ferritic stainless steel is bright-annealed at about 800-1,000 deg.C for about 0.5-3min in an atmosphere of decomposed gaseous ammonia or a gaseous N2+H2 mixture. The bright-annealed steel is immersed in an aq. soln. contg. 0.5-10wt% sodium silicate at room temp. - 100 deg.C for >=30sec. By the immersion, Mn oxide causing the deterioration of the rust resistance is dissolved and removed from a film formed by the bright annealing without losing the surface luster or dissolving Si oxide which is effective in improving the rust resistance. Thus, the rust resistance of the bright-annealed ferritic stainless steel is improved.

Title: Clamp circuit
Inventor: TACHIMORI HIROSHI
IPC: H04N5/18
Filed: 1998-10-26
Abstract: PROBLEM TO BE SOLVED: To provide a clamp circuit for preventing the fluctuation of the clamp level of a composite video signal and for improving an operating speed and operating precision. SOLUTION: A composite video signal SIN is inputted through a capacitor C1 to a node ND1, and the level of the node ND1 is compared with a reference voltage VCR by a comparator CMP1, and a comparator signal SOUT is transmitted through a chattering prevention circuit CHP1 so that chattering is prevented, and switching elements PT1 and NT1 are turned on/off. When the potential of the node ND1 is higher than the reference voltage VCR, the PT1 and NT1 are turned on according to an output signal SCO of the chattering prevention circuit CHP1. The ND1 is charged up and the potential of the ND1 is increased, and when the potential of the node ND1 reaches the reference voltage VCR, the PT1 and NT1 are turned off. Therefore, the potential of the node ND1 is set according to the reference voltage VCR.  Thus, the DC reference level of the composite video signal is set so as to be constant and the fluctuation of the clamp level is prevented.
