Title: Disk-like information recording medium and seeking method therefor
Inventor: YAMAMOTO NOBUO
IPC: G11B7/2407
Filed: 1994-04-26
Abstract: PURPOSE:To prevent the occurrence of seek error by detecting an idle track when it is sought by means of a recording/reproducing head. CONSTITUTION:An idle track 5a having an address region 51 only at the head sector part is provided at the border of respective bands 4a, 4b. The address regions 2a, 2b in the sector of each band 4a, 4b located at the head thereof are aligned with the address region 51 of the idle track 5a in the radial direction of a disc. Consequently, no address signal leaks from the address region 51 of the idle track 5a to the information recording parts 3a, 3b of adjacent tracks. When an idle track on such disc is sought by means of a recording/reproducing head, the idle track is detected based on the address thereof and the recording/ reproducing head jumps to a preceding or following track.

Title: Etching liquid for co alloy magnetic recording film
Inventor: ATOBE MITSUAKI
IPC: G11B5/84
Filed: 1986-04-17
Abstract: PURPOSE:To obtain an etching liquid which can remove only the magnetic layer without roughening an underlying Ni-P film by incorporating prescribed ratios of EDTA, hydrogen peroxide water, caustic alkali and water therein. CONSTITUTION:The EDTA, hydrogen peroxide water, caustic alkali and water are incorporated into the etching liquid. The volumetric concn. of the EDTA is 0.01-20%, the hydrogen peroxide 0.1-20% and the caustic alkali >=0.001M/l. The underlying Ni-P is roughened when the concn. of the EDTA is <=0.01. There is a problem in solubility if the concn. is >=20%. The effect of an etching characteristic decreases if the concn. of the hydrogen peroxide is 0.1% and a problem arises in workability at >=20%. There is not so much problem with the concn. of the caustic alkali and <0.01M/l is enough.

Title: Method for frictionally joining synthetic resin members
Inventor: ITO RYOSUKE
IPC: B29C65/06
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To join members to be joined together by performing a melting process so as to make a reference pressure coincide with a reference peripheral velocity when a pressure per the unit area of a joint face and a relative peripheral velocity on the joint face are previously sought during the melting process and another system is frictionally joined based on the pressure and the relative peripheral velocity as the reference pressure and the reference peripheral velocity. SOLUTION: A resin tube A1 is rotated at a specified peripheral velocity using a rotary chuck 30 and a resin tube A2 fixed to a clamp 31 is pressed against the resin tube A1 by a first air cylinder 34. The peripheral velocity of the resin tube A1 is sought as a reference peripheral velocity (reference value A) and a face pressure to be applied when the resin tube A2 is pressed against the resin tube A1 is sought as a reference pressure (reference value B). Thus these values A, B are used as reference set values when the resin tubes having different bores are frictionally joined together. When resin tubes having different bores from those of the resin tube A1 and the resin tube A2 are frictionally joined together, the frictional joining is performed at a peripheral velocity coinciding with the reference value A and under a pressure coinciding with the reference value B.  Consequently, it is possible to frictionally join the members to be joined together on favorable joining conditions.
