Abstract: PURPOSE: To effectively bond a metallic base material or to prevent the corro sion of the metallic base material by applying a coating material composition containing a beneficial polymer and a tertiary nitrogen-containing heterocyclic polymer at least on one part of the metallic base material.  
     CONSTITUTION: The coating material composition containing the beneficial polymer and the tertiary nitrogen-containing heterocyclic polymer is applied as an additive or an anticorrosive on the metallic base material such as a copper wire. As the beneficial polymer, a sulfur-containing thermoplastic resin such as poly(arylene sulfide) is used. On the other hand, as the tertiary nitrogen- containing heterocyclic polymer, a copolymer of N-vinylimidazol and N- vinylpyrrolidone or the like is used. In the composition, 98.5-97 wt.% beneficial polymer and 1.5-3 wt.% tertiary nitrogen-containing heterocyclic polymer preferably exist. The coating can be performed by applying the nitrogen-containing polymer as a solution and after that, applying a layer of the beneficial polymer thereon.

IPC: G11B5/455
Filed: 1994-08-31
Abstract: PURPOSE: To correctly observe a rotary head in the correct timing by generating a pulse based on a frequency signal synchronized with the rotary phase of the rotary head and lighting it in the timing based on the pulse. CONSTITUTION: When a rotary head drum device 10 in ratated, a pulse signal is outputted from a pulse generator 15 at a period T11 at every one revolution of a drum. In such a case, the output of a frequency generator 14 is converted to the frequency signal of 100 times by a PLL circuit 20. Thus, the output of the PLL circuit becomes the signal incorporating a jitter component synchronized with rotational unevenness when the rotational unevenness occurs in the rotary head. Then, the timing generating the pulse signal in a pulse generation circuit 32 becomes the correct timing so that the rotary head to be observed enters into the visual field of a microscope 41 even when the rotational unevenness occurs in the rotary head drum.
