IPC: C25D17/12
Filed: 1993-03-18
Abstract: PURPOSE:To satisfactorily secure a current path and to greatly exhibit a life prolonging effect by using titan. CONSTITUTION:Three electrode tips 13 formed of Ti, Nb, Pt, etc., are planted and provided at 120 deg. intervals in circumferential direction on a receiving plane 11 of a cylindrical electrode body 12 formed of Ti. A work W is so arranged as to be surely in contact with respective small receiving plates 13a of the three electrode tips 13 by a plane or a line even when the work W has some dispersion in the working accuracy. Thereby a bipolar phenomenon generating between a small radius axial part Wa of the work W and a cylindrical part of the electrode body 12 is suppressed and etchings liable to generate at the small radius axial part Wa are prevented.

Title: Retrieving device of magnetic tape
Inventor: SEKIGUCHI TOORU
IPC: G11B15/00
Filed: 1980-06-20
Abstract: PURPOSE:To realize quick and accurate automatic retrieval of a desired location without giving useless key-up, by having key-up at the desired location in accordance with the set preroll time when the recording is over to a magnetic tape. CONSTITUTION:When a search switch 11 of a key-up controlling part 9 is closed, the key-up mode is selected via a transfer controlling part 12. Then the record end signal is applied from a CPU via a bus line 4 simultaneously with the end of recording. Thus the cut number sent from an encoder 14 plus the preroll information set by a preroll time encoder 17 are transmitted to a CPU from a data switching part 15. Then key-up is carried out via an RAM or the like of the CPU and after the  tape is rewound so that the difference between the position of tape according to the  preroll extent and the present position becomes zero. Accordingly, useless key-up is not given with every recording, but proper key-up is carried out. As a result, tape retrieval is possible at a desired location in a quick and accurate way.

Abstract: PURPOSE:To obtain a picture with fidelity to an original picture from a printer by learning the relation among color data, an area occupied by the data and color data desired to be outputted as a correction function by means of a coupling weight of a neural network. CONSTITUTION:The weight of coupling of a neural network 4, that is, a correction function is decided by prescribed learning taking an area at the time of output into account. In the learning mode, color data of an output picture 7 and the area occupied by the data are used for input teacher data to the network 4. Moreover, color data from an input picture 1 are used for output teacher data. Since the output teacher data are obtained not through a printer 6, the data are data with fidelity to an original picture 1. In the processing mode, the color data of the picture 1 and the area occupied by the data are inputted to the network 4. The data are corrected by a learned correction function accordingly and the result is outputted. Since the color conversion rules of the color data are cancelled by the printer 6 as an output picture 7, the picture is a picture with fidelity to the input picture 1.
