Filed: 1988-03-11
Abstract: PURPOSE:To enhance the performance of the title magnetic head by forming an Fe-Si-Al-Cr alloy film at the connecting surface of a magnetic core half bodies consisting of ferrite with the use of a vacuum thin film forming technique, abutting a pair of the magnetic core half bodies, and forming a magnetic gap. CONSTITUTION:With the use of the vacuum thin film forming technique, an Fe-Si-Al-Cr alloy film 1 is formed at the connecting surface of the magnetic core half bodies consisting of ferrite 2, the magnetic core half bodies are abutted, and the magnetic gap is formed. In such a case, according to the increase of a Cr quantity, a temperature, at which magnetic characteristics start to deteriorate, becomes high, and heat resistance enhances. When the additive quantity of the Cr is large, however, the maximum value of the magnetic characteristics becomes low, and the practical use of the alloy film becomes difficult. Consequently, in the Fe-Si-Al-Cr alloy, the excellent result can be obtained when the Cr quantity is in the range between 0.1wt.% and 1wt.%, and the most preferable result can be obtained in the range of the Cr quantity 0.5wt.% to 0.8wt.%.

Filed: 1995-03-17
Abstract: PURPOSE: To shorten the time of adjusting operation for altering the structure and film quality of a transistor(TR) by finding variation in equivalent resistance corresponding to the state change of a flow controller for a medium. CONSTITUTION: In a step S1, a 1st terminal receives a specific fixed potential and a potential π is received between a 2nd terminal and a 3rd terminal to generate functional relation to a flow ϕ of the medium by using the potential πas a variable. In a step S2, the potential π of the functional relation is determined as a 1st border and a 2nd border. In a step S3, the potential π is used as an integral variable to integrate the reciprocal of the flow π of the medium from the 1st border to the 2nd border, thereby finding the equivalent resistance ρof the flow of the medium. In a step S4, variation Δρ in the equivalent resistance is found corresponding to the state change of the flow controller for the medium.
