Title: Apparatus for measuring refractive index
Inventor: NISHIDA KENJIRO
IPC: G01M11/02
Filed: 1986-05-10
Abstract: PURPOSE:To perform operation with high accuracy, by calculating the refractive index of an article to be measured by an optical means such as a critical angle or total reflection and the measurement of a distance. CONSTITUTION:Lights L, L' are received by a light receiving means 5 and the light receiving signal thereof is sent to an image processing part 6 while converted to an electric signal ep. The presence or light receiving position of the light L' is judged by the processing part 6 and a processing signal e'p is inputted to a calculation means 7. The means 7 inputs the output e'p of the processing part 6, the distance measuring signal ed of a magnetic type length measuring device (magnetic scale) 301 and the thickness of a glass plate 1 to operate a refractive index (n). A shield screen 8 blocks the light other than the light incident to the side surface part 101 of the glass plate in the irradiation light from a light source 4 from arriving the side of the means 5. When the light source 4 moves in the direction shown by an arrow A' so as to move away, the incident angle from the glass plate to an air layer at a boundary surface wherein the light in the glass plate 1 emits from the upper surface part thereof coincides with a critical angle. After this coincidence, the light incident to the glass plate is totally reflected to the under surface side of the glass plate 1 and the reception of light of the means 5 becomes extinct. By this method, highly accurate operation can be performed.

Title: Developing control device
Inventor: INUZUKA TSUNEKI
IPC: G03G15/00
Filed: 1978-09-01
Abstract: PURPOSE: To secure the reproducibility of images faithful to original pictures by using an elastic roller as a developing means, using the pressing force obtained from the slip state of a torque motor and detecting and controlling the surface potential of photosensitive drum with a sensor.  
     CONSTITUTION: A developing roller 65 during standing by is held dipped in developing solution, but upon starting of copying, it makes contact with a photosensitive drum 47 under constant pressure and revolves. Developing is accomplished by developing solution between the roller 65 and auxiliary electrode 104 which performs edge developing. Proximate field developing is accomplished by the developing solution oozed out from the sponge of the developing roller 65. Finally, the excess developing solution is absorbed by the recovery force of the sponge at the time when the roller detaches from the drum. These operations are electronically controlled by providing, e.g., automatic control circuit which detects the surface potentials of the photosensitive drum with a potential sensor and obtains a fixed contrast, etc., so that these may be accomplished always under respectively optimum conditions.

Title: Detector for double-feeding of paper sheets
Inventor: HAYASHI KENJI
IPC: G01B5/06
Filed: 1982-06-22
Abstract: PURPOSE:To accurately detect double feeding of paper sheets without a detector having high sensitivity by enlarging the displacement of the second roller by a lever in a detecting device for double-feeding of paper sheets for use in a printer or the like. CONSTITUTION:When two blanks P are passed between rollers 4, 5 at one time, a movable roller (the second roller) 5 is pushed down by about 1/100 to 5/100mm., which causes a support shaft 10 on the movable side, a rotary shaft 9 on the movable shaft and a lever 11 to rotate. The displacement of the movable roller 5 is enlarged by the lever 11 to operate a detecting rod 13 of a limit switch 12. Therefore, it is detected that two blanks P have passed by the operation of the detecting rod 13. Since the displacement of the movable roller 5 is enlarged by the lever, the need of a high-sensitive limit switch is eliminated, and besides, the sensitivity of the switch 12 can be easily adjusted.

Thereafter, the carriage unit 5 is retreated to the position at which printing is executed with the variable n=2 and further, the paper 10 is wound back to the same position. Then, the correction is carried out by using the type '30' of the character corresponding to the character code. A correction ribbon 21 eliminates ink by stripping the paper of the ink thereon according to the shape of the printing surface of the type 30. Consequently, the printing of the character of the special font is completed.

Title: Scramble method for television signal
Inventor: IDENO AKIRA
IPC: H04N7/171
Filed: 1989-04-28
Abstract: PURPOSE:To attain powerful prevention of interception by superimposing a pseudo key signal onto a part corresponding to a vertical blanking period of an audio signal and extracting a burst signal before and after the V synchronizing signal for several Hs and fixing the video signal portion by several Hs before the V synchronizing signal. CONSTITUTION:A pseudo key signal is superimposed onto an audio signal corresponding to the vertical blanking period and the information relating to the position of the vertical blanking period is included in the key signal. A color burst for a prescribed number of horizontal synchronizing periods inserted before and after the vertical synchronizing signal in the vertical blanking period is eliminated and the video signal for a prescribed number of vertical synchronizing periods before the vertical synchronizing signal is fixed to a prescribed level. Thus, even when the audio signal is detected, it is unable to detect the VBI period. Moreover, the timing of an expansion pulse in the VBI period generated based on the detection of the color burst and the detection of the absence of the video signal is deviated from the substantial position of the VBI period and the descrambling to obtain a normal picture is not implemented. Thus, interception is made hard.
