Title: Element for consumer appliances
Inventor: INABA MICHIHIKO
IPC: C22C9/00
Filed: 1983-03-29
Abstract: PURPOSE:To eliminate or minimize a compound between metals at a junction preventing this compound from exfoliating by a method wherein an Fe concentration and diffusion diminishing layer by means of Zn concentration is formed at a junction of a solder and a metallic element comprising copper, iron and zinc. CONSTITUTION:An Fe concentration and diffusion diminishing layer 4 uilizing Zn is formed at a junction of a metallic element comprising copper, iron and zinc and a solder comprising lead and tin. For example, the constituents composing a metallic element 5 may be composed of Cu as main constituent and 1- 5wt% of Fe, preferably 1.2-4% as an additional constituent and 0.1-3wt% of Zn preferably 0.3-2.8% as another additional constituent. Furthermore, the recommended ratio of Zn to Fe may be Zn%>=1/20 Fe %. Through these procedures, the Fe concentration and diffusion diminishing layer 4 by means of Zn concentration in Cu-Zn diffusion layer may be formed between the metallic element 5 and a solder 2. Said layer 4 as a solid solution layer may be almost equal to Sn-Cu solid solution layer in terms of junction strength also preventing Fe diffused in Cu from concentrating.

IPC: G11B5/592
Filed: 1984-03-17
Abstract: PURPOSE:To obtain stable reproduced pictures at varying speeds, by storing positional information of a recording track and plural rotary heads at a prescribed time, and then, using the stored positional information as the information signal of a converting means after the difference between the tracing locus of the heads and inclination of the recording track is added to the positional information. CONSTITUTION:Reproduced signals obtained from reproducing heads 2A and 2B contain video signals and pilot signals for tracking. The reproduced signals are supplied to a video signal reproduction processing circuit 52 after they are amplified by a reproducing amplifier 51 and, at the same time, changed to continuous signals by changeover signals. The circuit 52 separates video signals from the output signal of the reproducing amplifier 51 and also performs processing of modulation, etc., and supplies reproduced video signals having the original signal form to an output terminal 50. On the other hand, at a tracking signal generating circuit 53 pilot signal components are separated from the amplified reproduced signals and levels of pilot signals obtained from both adjacent tracks are compared with each other, and then, tracking controlling signals are obtained by detecting tracking errors on the reproducing heads 2A and 2B. Therefore, high-quality reproduced pictures are obtained at varying speeds.
