    摘要: An exothermic resistor for use in a hot wire air flow meter, having a wire (2) in the form of a coil made of a metal, a pair of lead wires (3) connected to connections (21) formed at the opposite ends of the coil, and a support member (4) which integrally supports the connection as well as the coil located between the connections. An example of the support member is in the form of a tubular cylinder closed at its both ends. The support member is formed from glass only or formed of a layer of a glass-ceramic-composite material. The hot wire air flow meter is designed to be easely mass-produced and to have improved transient response characteristics with respect to abrupt changes in the air flow rate.

    摘要: A method of manufacturing a magnetic head includes fabricating a magnetic block having a lamination of magnetic alloy films and nonmagnetic substrates, and cutting the magnetic block into two bars to obtain magnetic core halves. A nonmagnetic film is formed on a surface of each of the core halves. The core halves are joined by adjoining the surfaces having the nonmagnetic film and then heating the thus adjoined core halves. Additionally, a magnetic field is applied rotating in a plane parallel to a plane of the magnetic alloy films. The joined core halves is then cut into a specified width, and a wire-winding window is machined therein.

    摘要: A perpendicular magnetic head of high recording and reproducing efficiency which integrally incorporates a step-up transformer. A main pole for picking up a reproduce magnetic flux from a recording medium and applying recording magnetic field thereto is formed of a magnetic thin film. A signal winding formed of a thin film is disposed in the immediate vicinity of the forward end of the main pole so as to have a high conversion sensitivity per turn with respect to the reproduce magnetic flux from the recording medium. The signal winding which itself constitutes a closed circuit interlinks a magnetic path of the step-up transformer, thereby forming a primary winding of the transformer. A secondary winding from which head output is taken out is wound in the magnetic path of the transformer.
