Inventor: HAMANAKA SHINJI
IPC: C25D11/22
Filed: 1992-08-05
Abstract: PURPOSE:To obtain a colored film of a desired color with excellent reproducibility even if the ambient conditions such as the chemical conversion condition of an anodic oxide film, the treating area, etc., are different by applying a current at the maximum set value for a specified time to conduct the intermediate treatment of the tertiary electrolytic coloration of an Al-base metal.

Accordingly, the maximum current value is set in accordance with the treating area and desired color. When electrolysis is carried out at the AC current value, the colored film of the desired color is surely obtained, and the color reproducibility is enhanced. In this case, although the maximum current value is affected by the acid concn. and processing soln. temp., the reforming degree of the film is not varied since the maximum current value is preset.

IPC: G11B5/187
Filed: 1984-10-30
Abstract: PURPOSE:To decrease generation of 'negative edge' inherent to a thin film magnetic head by providing a means for relaxing a magnetic flux near the tip of a magnetic substance. CONSTITUTION:A projection 23 whose tip is opposed to a medium contact face side is formed to a face of the side of a base 11 near the tip of a lower magnetic substance 22, and the tip of the projection 23 is not flush with the face of the tip of the magnetic substance on a face opposed to the medium but placed slightly (nearly 1mum) at the inner side than the tip face. Further, an insulation member 24 made of alumina being the same material of a protecting layer 81 is formed to the tip projected by the said 1mum. The magnetic substance 22 having the projection 23 like this is obtained easily by the method of sequential lamination of the projection part and the magnetic pole part. Through the forming of the projection 23 above, for example in case of the signal reproduction, a part of the magnetic flux near the edge A of the lower magnetic substance 22 is absorbed to suppress the concentration of magnetic flux to the said edge thereby decreasing extremely the 'negative edge' in the reproduced waveform.

Title: Interruption processing method for remote supervisory and controlling system
Inventor: MIURA TOSHIBUMI
IPC: H04Q9/00
Filed: 1994-09-26
Abstract: PURPOSE: To provide an interruption processing method for a remote supervisory and controlling system in which the dispersion of retrieval time of a terminal machine from which an interruption processing request by a master machine is issued can be prevented from occurring. CONSTITUTION: When an interruption request signal is issued from the terminal machine, the master machine 1 sends out an interruption polling signal sequentially at every prescribed group, and performs interruption processing on a specified terminal machine 32b. Thence, the group which sends out the interruption polling signal first when the next interruption processing is performed is decided by using the address information and interruption processing number of times information of the group to which the group belongs stored in a storage part 6 and by which the interruption processing has been performed just before. In this way, the dispersion of the retrieval time of the terminal machine from which the interruption processing request is issued at every group can be eliminated.
