摘要： PURPOSE:To write and read magnetic signals with the one magneto-optical composite magnetic head by providing thin films having a magneto-optical effect and a substrate in the gap part between the opposite magnetic cores of a magnetic head part and setting the width of these thin films smaller than the width of this substrate. CONSTITUTION:The light emitted from a light emitting element 10 is transmitted by an output side fiber 11 and only the single plane of polarization is transmitted by a polarizing film 12 on a light projecting side. The transmitted light is made incident on a magnetic garnet film 13 through the substrate 4. The magnetic garnet film 13 is magnetized by the magnetic field generated from a body to be detected, such as magnetic tape or magnetic disk, near the protective film at this time and, therefore, the plane of polarization is rotated by the Faraday effect of the compsn. of the garnet film 13 and is further reflected by a reflection film 14 so as to be returned to the garnet film 13. The plane of polarization of the light is again rotated 45 deg. within the garnet film 13 and is made incident through the substrate 4 and through a polarizing film 15 ion the outlet side which is an analyzer on an input side optical fiber 16 from which the light is made incident on a light receiving element 17. Magnetic information is detected from the rotation of the plane of polarization of this light.

摘要： PURPOSE:To discriminate between an original object containing information displayed by magnetic ink and its copy produced on a copying machine using magnetic toner. CONSTITUTION:By sliding a composite optical/magnetic sensor 4 relatively to an object 3 to be detected on which optical information 1 and magnetic information 2 marked with a magnetic material are displayed, magnetic signals and optical signals are respectively obtained from the magnetic information 2 and optical information 1 by means of the sensor 4. The optical signals are obtained from the sliding surface 5 of the object 3 and the magnetic signals are obtained from both the sliding surface 5 and rear surface 6 of the object 3. In addition, the magnetic signals and optical signals thus obtained are combined with optical signals and magnetic signals separately detected from the sliding surface 5 of the object 3. In addition, optical signals detected from the sliding surface 5 and rear surface of the object 3 and magnetic signal detected from the surface 5 only are combined separately from the above-mentioned signals.

摘要： PURPOSE:To provide a magnetic/optical composite recording medium which is difficult to alter and duplicate for tighter security by recording magnetic information on a magnetic recording layer and realizing the display of optical information using an ink having wavelength characteristics in the invisible light range on the sheet provided on the recording layer. CONSTITUTION:Optical information in the magnetic/optical composite recording medium can be altered by attaching an alteration sheet 21 on the optical information or replacing the optical information with other optical information. However, if the alteration sheet 21 is attached, the distance between a magnetic head 22 and a magnetic recording layer 1 changes. Consequently, the magnetic signal level detected by the magnetic head 22 changes, thus making it possible to detect an alteration. In addition, if another bar code is attached, data which is read from the code is different from a genuine bar code, so that the alteration can be easily detected. Further, it is virtually impossible to interpret conditions, because part of the optical information of this composite recording medium is an invisible light range, and therefore, data cannot be duplicated.

摘要： PURPOSE:To decrease the transmission loss of optical fibers in an optical head. CONSTITUTION:A light emitting element 1 and a photodetector 2 are housed in an optical sensor. The light from the light emitting element 1 is guided through a plurality of incident optical fibers 3 and projected on a body to be detected. The reflected light from the body to be de detected is guided to the photodetector 2 through a plurality of optical fibers 4 on the emitting side in the optical sensor. As the light emitting element 1 and the photodetector 2, a light emitting chip 5 and a light receiving chip 6, which are not packaged, are used. Therefore transmission loss is less, and the compact optical sensor is obtained.

摘要： PURPOSE:To prevent the end face of a bridge from being exposed at a surrounding cut surface, to protect a circuit conductor at the cut surface against short circuit at the soldering of components, and to protect the circuit conductor against corrosion which starts from the cut surface by a method wherein a bridge between an edge frame conductor and a circuit conductor is cut off before an outer shape processing takes place, and resin is filled into holes or a groove induced at the cut of the bridges. CONSTITUTION:When a bridge 15b between circuit conductors 14 is cut, a bridge 15a between an edge frame conductor 13 and a circuit conductor 14 is cut off concurrently. A resin 19 is filled into a hole 19 induced when the bridge 15a is cut off and set. At this point, resin may as well be filled into a hole 9 induced when the bridge 15b is cut off. Then, an outer shape process in which a surrounding edge frame conductor 13 is cut off along a dotted line to remove is carried out to obtain a circuit board 20. In the board 20, as a hole induced at the time when the bridge 15a is cut off is filled with resin 19, the end face of the bridge 15a is prevented from being exposed at a surrounding cut surface, therefore the circuit conductors at both the sides are protected against short circuit and against corrosion which starts from the exposed part.
