Title: Improvement of rust resistance of bright-annealed ferritic stainless steel
Inventor: UGI TAKUMI
IPC: C23F3/00
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 NaOH at a proper temp. for a proper time. CONSTITUTION:A ferritic stainless steel is brought-annealed at about 800-1,000 deg.C for 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. 1-20wt% NaOH at room temp. - 100 deg.C, preferably about 60-80 deg.C for >=1min. By the immersion, Mn oxide in a film formed by the bright annealing is dissolved and removed together with Si oxide. Thus, the rust resistance of the bright-annealed ferritic stainless steel is improved without losing the surface luster.

Filed: 1992-10-20
Abstract: PURPOSE:To provide the facsimile equipment avoiding a defect of communication caused when picture information is sent in succession to an echo protector tone(EPT) signal. CONSTITUTION:When an EPT signal is outputted in compliance with the recommendations CCITT V.29, a frequency of 1700Hz has been used for the signal in a conventional equipment. Then the frequency signal is mis-detected from a preamble (1650Hz) of a DCS command and a communication fault may take place.

Title: Lead frame for semiconductor and manufacture of it
Inventor: SUZUMURA TAKASHI
IPC: H01L23/50
Filed: 1993-12-07
Abstract: PURPOSE:To make wire bondability better by making a lead frame layer out of copper material, and not performing the surface processing of the surfaces of the lead frame layers for rust proofing. CONSTITUTION:Since a lead frame layer 10 and a metal plate layer 1 are laminated interposing a thermoplastic adhesive layer 2, curing for joining is unnecessary, and an out gas caused by joining is scarcely produced, and the silver platings 3a of inner leads 3 are kept clean. Since the lead frame layers are made out of copper material, and the surfaces of the lead frame layers are not surface-processed for rust proofing, outer leads 4 are coated by solder plating after sealing them with molding resin. Generation of cracks in solder platings caused by the cracks in a layer formed by surface processing for rust proofing is prevented at the time of bending these outer leads 4. Besides, it becomes possible to obtain semiconductor packages excellent in thermal and electric conductivity.
