Abstract: PURPOSE: To improve image quality by providing an optimum signal processing band by providing an EDTV-2 identification control signal reproducing circuit, an HH component reproducing circuit, a luminance signal frequency band limiting circuit and a contour emphasis circuit in the next stage. CONSTITUTION: At the time of receiving EDTV-2 signals, identification is performed in an identification control signal reproducing circuit 6 and luminance signal high frequency components are reproduced in a horizontal luminance high frequency component (HH) reproducing circuit 5 and superimposed on main image luminance signals. The band limiting circuit 2 of the next stage receives identification signals and stops a band limiting operation, luminance signals are inputted to a horizontal contour emphasis circuit 3 while keeping a wide band as it is and the video signals of the wide band are displayed. In the case of receiving a normal ground line, an identification control circuit judges normal signals, the HH reproducing circuit 5 is not operated and the luminance signals are added to the band limiting circuit 2.  In the case of the normal signals, since the band limiting circuit 2 is operated, the luminance signals are band-limited and then inputted to the horizontal contour emphasis circuit 3 and frequency components outside of the band are not displayed, the video images of high image quality are displayed.

Abstract: PURPOSE:To measure a radiation dose distribution along an optical fiber for a sensor spatially and with passage of time. CONSTITUTION:An optical fiber 3 for a sensor is laid long in a radiation exposure area. A light of a single wavelength lambda0. outputted from a light source 1 is made to enter this optical fiber 3 from one end thereof. A back scattered light generated in the optical fiber 3 for the sensor and coming back is led to a light branching unit 2 and an anti-Stokes light and a Stokes light being different in a wavelength are taken out of it. Distance distributions of the two kinds of lights taken out are measured discretely by light pulse testers 10a and 10b. Outputs of these pulse testers 10a and 10b are received by a radiation dose distribution computing circuit 9, a change in a transmission loss is determined for each wavelength, and the distribution of a radiation dose along the optical fiber 3 for the sensor is computed spatially and with passage of time, from this change.

Title: Charging controller of electrostatic recorder
Inventor: SUZUKI KOUJI
IPC: G03G15/00
Filed: 1981-03-16
Abstract: PURPOSE:To correct the ambient change and secular change of a photosensitive drum, and also compensate moisture absorption characteristics completely, by controlling the extent of charging to a recording body according to both the output of a means of detecting the ambient humidity of the recording body and that of a means of compensating charging characteristics. CONSTITUTION:When a timing signal synchronizing with the charging rotation of a photosensitive drum is applied to a terminal 17 and the powering-up timing of a power source for circuit driving nearly coincides with the charging rotation of the photosensitive drum, a constant voltage is inputted to a terminal 17. Then, a transistor Q6 turns on and the discharging of a capacitor C1 is started with a time constant C1.R1.R2/ (R1+R2), so that a voltage at a connection point of resistances R1 and R2 according to  an exponential function. When the output voltage of a temperature sensor 13 is high at this time, a small voltage is applied to a time constant circuit 15, so a corona current decreases as humidity increases to correct the initial value in the beginning of charging while considering humidity conditions. The output of the circuit 15 is inputted to a high-voltage generating circuit 19 to control a voltage applied to a primary charger 2, thus controlling the extent of charging to the photosensitive drum.

Title: Digital magnetic recording and reproducing method
Inventor: IDE AKIFUMI
IPC: G11B15/467
Filed: 1990-02-16
Abstract: PURPOSE:To detect a tracking error without generating cross talk by detecting a tracking state with a frequency spectrum mode of a signal corresponding to a part of a pilot signal. CONSTITUTION:A magnetic tape is recorded to be inclusive of the pilot signal that is intermittent in a track on a magnetic tape and different between the adjacent tracks, and at the time of reproducing, the tracking condition is detected by the frequency spectrum mode of the signal corresponding to this pilot signal part. Consequently, the frequency spectrum state of the taken-out signal is varied in relation to the tracking condition of a reproducing head, so that the tracking state can be detected, and based on this, the tracking control is feasible even for digital magnetic recording. By this method, a generating period of cross talk is reduced, and the tracking condition can efficiently be detected.

Title: Lamp disconnection detector
Inventor: TSUKADA KOUICHI
IPC: G01R31/02
Filed: 1979-03-28
Abstract: PURPOSE: To accomplish accurate indication of lamp disconnection for vehicles or the like by means of a switch which is adapted to maintain the switching state at the inputting of the lamp disconnection signal while the state is inverted between the inputting of the lamp disconnection signal and the inputting of non-disconnection signal.  
     CONSTITUTION: When lamps for vehicles or the like, for example, stop lamps 4aW 4d, are normal with the stop switch 2 on, the current from the resistance 11 is cut with a transistor (Tr) 14 off as the lead switch is turned off. Thus, the lamp 5 stays off. On the other hand, when any of the lamps 4aW4d is disconnected even with the switch 2 on, as the lead switch 8 is turned off, the current from the resistance 11 flows to the transistor 14 with a lag time of the capacitor 13. Thus, the transistors 14 and 15 are turned on to allow the lamp 5 thereby indicating the disconnection of the lamp. Under such a condition, the transistors 14 and 15 feeds base current to each other, allowing the transistors 14 and 15 to maintain the on state even if the switch 2 is turned off.
