Title: Magnetic head and manufacture of magnetic head
Inventor: OSAWA YUICHI
IPC: G11B5/39
Filed: 1999-03-15
Abstract: PROBLEM TO BE SOLVED: To make avoidable films from being concentrated at the top portion of a magnetic gap when burying the magnetic gap by forming, between magnetic materials and the magnetic gap, a layer having a composition different from those employed for constituting the magnetic materials and the magnetic gap. SOLUTION: A magnetic gap 14 is interposed between first and second magnetic materials 13 that form a magnetic yoke 12. As the magnetic material 13, a soft magnetic material such as an amorphous alloy, e.g. a NiFe alloy or a CoZrNb alloy, is used. Between the magnetic materials 13 and the magnetic gap 14, a chemical reaction layer 21 having a composition different from those employed for constituting the magnetic materials 13 and the magnetic gap 14 is formed. A thickness of the chemical reaction layer 21 is desirably set in the range from 1 nm to 20 nm. The chemical reaction layer may be a chemical reaction layer from at least one element among the constituent elements of the magnetic materials. For example, an oxide, a nitride, a fluoride or the like of one element is used.  In addition, the magnetic gap 14 is formed by an electrochemical technique such as a plating method, a selective CVD method or the like.

Title: Microwave probe
Inventor: HATTA SHINJI
IPC: H01P1/06
Filed: 1989-03-23
Abstract: PURPOSE:To provide information throughout the wide range of a portion deep in a body cavity by a method wherein a microwave antenna mounted to the tip of a probe is provided rotatably in a direction extending at right angle with the axis in the longitudinal direction of the probe. CONSTITUTION:A probe 1 alone or in a state to be incorporated in an endoscope is inserted in a body cavity. In which case, microwaves from a given direction are received by an antenna 2. In this case, radial scanning is effected through rotation of a shaft 4 by means of the rotation power of a motor 6. An encoder is used for detection of a rotation position. Through rotation of the shaft in a manner described above, a diagnosing region is switched. For example, through the decrease of a rotation speed, a far portion is diagnosed, and through the increase of it, a near portion is diagnosed. Microwave information is reliably transmitted by high dielectric parts 12 and 13 and received by a receiving circuit, and a signal is processed to display a result on a display part. When the microwave antenna 2 is used not only as an organism tissue receiving means but also a transmitting means through the medium of a switching part, information is obtained by radial scanning in a similar manner described above.

Title: Multifrequency signal receiver
Inventor: AIISO ATSUSHI
IPC: H04Q1/45
Filed: 1988-03-24
Abstract: PURPOSE:To prevent a multifrequency receiving means from misdetecting a voice signal as a multifrequency signal by preventing a disconnecting means from inputting into the multifrequency receiving means when the voice signal containing more other components than the frequency component of the multifrequency signal to be a reception subject flows in as an input signal. CONSTITUTION:When a multifrequency signal Z is inputted as an input signal W, the multifrequency signal Z of which conductive condition is maintained by a switching part 132 is transmitted to a multifrequency signal reception part 134 and a low frequency signal Li and a high frequency signal Hj are detected. On the other hand, when a sound signal V is inputted as the input signal W, the switching part 132 maintains a disconnecting condition and the voice signal V is prevented from being transmitted to the multifrequency signal reception part 134. Thus, it is prevented to erroneously detect the low frequency signal Li as the high frequency signal Hj from the sound signal V.
