Title: Magnetic tape transfer device
Inventor: KUROE AKIO
IPC: G11B5/86
Filed: 1982-11-18
Abstract: PURPOSE:To apply easily a transfer bias magnetic field at a prescribed angle by providing a transfer bias generator which contains a projected sliding part for tape winding and the 1st magnetic pole set with a shift from the projected maximum position with the 2nd magnetic pole set at the same side as both tapes, respectively. CONSTITUTION:For a transfer magnetic field generator 92, a sliding part 95 is formed by molding the 1st magnetic pole 94 with glass 93. The 2nd magnetic pole 96 and an energizing winding 97 are provided at the same side as the pole 94. A transfer bias current is supplied to a winding 97 to produce a magnetic field and then to magnetize the pole 94. Thus an intensive transfer magnetic field 98 is generated at a place near the pole 94, and the signal of a master tape 84 is transferred to a slave tape 85. The width (t) of the pole 94 is reduced at less as possible for satisfactory magnetization of the tape 85. Furthermore, a larger transfer bias is also obtained by controlling the width (t) and the distance (h) of the pole 94. The direction of magnetic field is decided by the distance l in the tape lengthwise direction of both magnetic poles and the diameter R of the tape sliding part.

Abstract: PURPOSE:To facilitate a gas pressure adjusting operation, reduce the number of steps of inspection and time required for performing a changing of gas by a method wherein a flow rate of gas flowing through a main nozzle and a pilot nozzle is controlled by one gas burner. CONSTITUTION:A main valve 3, a main governor 7 and a hydraulic pressure responding valve 10 are arranged in a gas passage between a gas connection port 1 and a main burner 13, gas for a pilot nozzle 14 is supplied through a pilot gas passage 8b branched from a main gas passage 8a extending toward the main nozzle 12. Then, a control over a flow rate of gas for the pilot nozzle 14 and a control over a flow rate of gas for the main nozzle 12 are performed through the main gas governor 7, and a setting of pressure in the pilot nozzle 14 is dependent upon a pressure adjustment of the main gas governor 7. In this way, the pilot gas passage 8b communicating with the pilot nozzle 14 is branched from a secondary side of the main gas governor to enable the flow rate of gas in the pilot nozzle to be controlled, and at the same time it is possible to reduce the number of steps of inspection in a manufacturing process and to shorten the changing operation under a simplified gas changing operation.

Filed: 1987-08-19
Abstract: PURPOSE:To quickly control a variable (p) with a high precision by immediately performing switching between the control due to final control element A and that due to the other in case of the process change. CONSTITUTION:An industrial process 1 is provided with a final control element A which controls two control variables (p) and (q) and a final control element B which controls only the control variable (p). A first regulator 2 outputs a controlled variable (px) for the control variable (p) and a second regulator 3 outputs a controlled variable qx for the control variable (q), and a comparing and computing element 4 compares the controlled variable px and the controlled variable (qx) with each other and outputs the smaller controlled variable (px) or (qx) as the controlled variable for the final control element A. For example, if the output (px) of the first regulator becomes lower than an operation end switching level (po) when the final control element A controls the controlled variable (q) and the final control element B controls the controlled variable (p), the controlled variable (px) is forcibly changed to a value smaller than the controlled variable (px) across a gap area C. Thus, the controlled variable (p) is immediately controlled by the final control element A without a lag.

Abstract: PURPOSE:To improve the rust preventing performance of a metallic material by bringing the material into contact with a soln. contg. soluble V ions and phosphate ions in the presence of water and oxygen which produce corrosive conditions. CONSTITUTION:A metallic material is brought into contact with a soln. contg. soluble V ions and phosphate ions in the presence of water and oxygen which produce corrosive conditions. The phosphate ions lack the function of an oxidizer and the V ions compensate for the function.

The phosphate ions form a film of a slightly soluble precipitate under the corrosive conditions and has a deposition function. Very high rust preventing performance is obtd. by the presence of the two kinds of ions.
