Abstract: PURPOSE:To discriminate whether an accumulating phosphor sheet is normally housed or abnormally housed while keeping it housed by providing an aperture on either of front side and rear side casings and making a part corresponding to the aperture on the other side a part having light reflectance different from the housed phosphor sheet. CONSTITUTION:The aperture 32 is provided on one (rear side) of the front side and rear side casings 14 and 16 having sliding members 36 and 34 only on the housing surface of one side and the light reflectance is made high on the part corresponding to the aperture on the other side (front side) so as to constitute a holder 10 for an accumulating phosphor. By making a reflection type sensor 40 to correspond to the aperture 32, irradiating light 42 projected from a sensor 40 is reflected on the rear side 12b of the accumulating phosphor 12, but the reflected light 44 is little and received light quantity is extremely small because the rear side is black, etc. Such state is discriminated to be a normally housed state. When the front surface 12a of the sheet 12 is detected, received light quantity is large because the front surface side is white, etc., and the state is discriminated to be an abnormal state in the same way. When the sliding member 36 is detected, received light quantity is large because of its high reflectance and the state is discriminated to be the abnormal state, that means, an empty state. Therefore, the abnormal state where the sheet is housed reversely or the holder is empty is easily discriminated.

Title: Video signal magnetic recording and reproducing device
Inventor: IDE AKIFUMI
IPC: G11B20/22
Filed: 1982-05-13
Abstract: PURPOSE:To suppress crosstalk between adjacent tracks, by giving no azimuth angle to a track for recording a luminance signal component which becomes reference of a time base at the time of reproducing, and giving an azimuth angle to other track. CONSTITUTION:When a magnetic head for a luminance signal traces on a locus 61, a level of a signal outputted from the magnetic head for a luminance signal becomes a tangent 65. As the head traces, a track shift increases, an output of the magnetic head decreases gradually, and at the point of time when it traces just half the locus 61, a signal reproduced from a track 55 is gone, and thereafter, a signal reproduced from a track 67 increases gradually. On the other hand, as a magnetic head for a color signal traces a locus 62, it becomes an output level shown by a tangent 67. Subsequently, the same change as the case of the magnetic head for a luminance signal is caused, but an azimuth angle is given to the magnetic head for a color signal, therefore, variation on the time axis is varied in accordance with a polygonal 68.

Title: Method for recording and reading electron-microscopic image
Inventor: MORI NOBUFUMI
IPC: H01J37/22
Filed: 1985-04-17
Abstract: PURPOSE:To enable the electron-microscopic image to be accurately read by recording it on a secondary sensor while it is positioned oblique to the axis of the electron beam and irradiating light from an excitation means perpendicularly to the sensor to read the recorded image and then converting the read image by means of a signal-treating circuit. CONSTITUTION:After a magnified scattered image of a sample 8 is recorded on an accumulation phosphor sheet 11 used as the secondary sensor, light produced from the accumulated energy is emitted from the sheet 11 to produce an image, thereby recording and reading an electron-microscopic image. After a magnified scattered image 8b of the sample 8 is accumulated in the sheet 11 while it is positioned obliquely to the axis of the electron beam, light from a light source 12 is almost perpendicularly scanned over the sensor 11 through deflecting elements 13a and 13b and then light emitted from the sheet 11 is received by a photomultiplier 15. Next, the signal from the photomultiplier 25 is converted into an image on an imaging surface perpendicular to the axis of the electron beam, thereby producing an image 23. Accordingly, it is possible to perform accurate reading by producing a homogeneous scanning beam.
