Title: Discriminating apparatus for structure of track
Inventor: HONMA KAZUYA
IPC: E01B29/04
Filed: 1993-05-13
Abstract: PURPOSE:To automate the work of maintaining a track, by a method wherein the difference among a sleeper, a ballast part and a rail joint is discriminated by an image-processing apparatus mounted on a working car for maintenance, and the work of maintaining the track is done at a definite position based on the result of its discrimination. CONSTITUTION:When an image-processing apparatus 13 discriminates a sleeper 3 from a rail joint by the processed image of a slit light figure caught by a camera 12, the result of its discrimination is outputted to a control device 14. After that, the device 14 drives a tamping tool 8 for ballast and a clamping tool 9 for the correction of a bad track, which are provided in a working mechanism 7. In the case of the tamping tool 8, the tool 8 is prohibited from driving when opposed to the position of the sleeper 3 discriminated, and is restarted when passed trough the sleeper 3. In the case of the clamping tool 9, when the tool 9 reaches the position of the rail joint during clamping work, the tool 9 is prohibited from doing clamping work while passing through the rail joint. Furthermore, during these construction, distances L1, L2 from a place to be discriminated to these tools 8, 9 are respectively measured by a measuring apparatus 15 for the distance of movement and these operations are prohibited. In this way, labor saving can be attained by automating these work can be improved.

Abstract: PURPOSE: To form a correction signal in accordance with the difference between pulse frequency signals generated by A/D-converting pulse widths and to use the signal in cooperation with multichannel pulse analysis for automatically correcting the align ment of pulse height distribution. CONSTITUTION: A gas ionization detector is used as an X-ray detector 6. The fluorescent X-ray beam 9 which is emitted from a sample 8 when an X-ray beam 7 is made incident to the sample 9 reaches the detector 6 through a collimator 3, an analyzing crystal 5, and a collimator 4. By rotating the crystal 5, the energy of the X-ray beam made incident to the detector 6 is selected within a narrow zone. The detector 6 is moved along a circular arc 15 by means of a motor 12. The amplitude of the analog signal generated from the detector 6 is controlled by means of a gain control circuit 6 and converted into a digital form by means of an A/D converter 17. The amplitude of the signal generated from the detector 6 coincides with the energy of the X-ray photon made incident to the detector 6.  Therefore, the frequency distribution of the amplitude of the signal coincides with the energy distribution of the X-ray photon made incident to the detector 6.

Title: Video signal recorder and reproducer
Inventor: NINOMIYA TAKESHI
IPC: G11B15/18
Filed: 1983-06-21
Abstract: PURPOSE:To reproduce all information recorded on a recording track without omission by scanning a rotary video head for recording in the same direction that a tape runs. CONSTITUTION:A tape running direction (a) and head running direction (b) are selected (in the same direction), so that they do not oppose to each other. When their running directions are selected in such a way, a track is represented by the summed vector of a vector V11 opposite to the tape running direction (a) and another vector V12 representing the head running direction (b) and a video signal is recorded in a direction from the upper end Q2 to the lower end O1. When the recording track is formed with the tripled tape running speed, the angle thetaH of the head scanning locus against the tape running direction (a) becomes gradually smaller as the operation mode becomes a slow mode (double speed, normal speed), still mode, and reverse mode and, as a result, the length of the head scanning locus becomes longer than the track length. Therefore, all information recorded on the recording track is reproduced without omission.
