Title: Pattern input/output unit
Inventor: OOBA SHIGERU
IPC: G06K11/00
Filed: 1978-08-24
Abstract: PURPOSE: To secure the free erasion for the pattern delivered once by providing the booster circuit as well as the switch circuit which switches the direction of the application voltage via the pattern output/erasion switch signal when the voltage is applied between the X and Y direction conductors.  
     CONSTITUTION: Conductor particle 24 and paper 25 are held between two sheets of upper and lower insulated flat plates 23 to which conductors 20i and 21j are stuck in parallel to the X and Y directions, thus forming tablet 22. The voltage is applied over the tablet and between the X and Y conductors via magnetic pen head 27 containing coil 26. In this case, the orthogonal conductors are selected continuously by one piece from X and Y booster circuits 18 and 19 via output/erasion switch circuit 40 and by the command of arithmetic control unit 1. Thus the desired pattern is delivered. For erasion of the pattern, the switch is changed over for circuit 40 to apply the reverse electromotive force. At the input time of the pattern, pen head 27 is pressed to tablet 22 to turn on switch 28. And then the pulse current is flowed to coil 26 from discharge circuit 29, and the coil position is calculated from the reverse electromotive force of conductors 20i and 21j to the change of the magnetic flux generated.

Title: Fine powder separation device
Inventor: TAGASHIRA KENJI
IPC: G01N1/02
Filed: 1993-04-28
Abstract: PURPOSE:To improve a sampler used for the analysis of exhaust gas from a device for preparing fine powder using coal cinders at high temperature, a fine powder separation device used for a magnetic material manufacturing device which manufactures the fine powder by gas phase reaction or an incinerator, especially exhaust gas containing a high concentration of the powder before dust collection. CONSTITUTION:A filter 16 is installed in a rotor 10 which rotates at high speed. Gas containing dust flow toward the center of rotation from the outer periphery of the rotor 10, and in this case, is screened using a filter 16 installed in a flow path. The apparent weight of a filter medium increases due to centrifugal force, so that flow velocity for filtration can be increased. In addition, fine powder sticking to the surface of the filter comes off spontaneously as the centrifugal force becomes stronger than the cohesive power or a particulate layer, if the fine powder layer is thicker than specified. Consequently, back wash operation is no longer required, if dust gas of high concentration has to be filtered.

Title: Information recording paper with mark
Inventor: KASHIOKA MOTOHIKO
IPC: B42D15/10
Filed: 1990-04-19
Abstract: PURPOSE:To prevent the forgery of an information recording paper by displaying a detection mark like a timing mark, etc., on the upper or rear surface of the information recording paper with use of the detection ink containing a near infrared ray absorbent except the carbon black that has the absorbing force to a specific wavelength of at least 700 - 1500nm. CONSTITUTION:A detection mark like an end mark, a position mark, a counter mark, a timing mark, etc., is displayed on the upper or rear surface of an information recording paper with the display ink containing a near infrared ray absorbent except the carbon black that has the absorbing force to a specific wavelength of at least 700 - 1500nm. Thus the application of a color mark is facilitated with use of such an almost colorless detection mark that has the detection sensitivity equivalent to a black mark using the conventional India ink and can be used with other coloring matters as necessary. However the satisfactory detection sensitivity is not obtained even with use of a closely resemble hue only. Thus the forgery of the recording paper can be prevented.

Filed: 1985-05-17
Abstract: PURPOSE:To obtain a high aligning accuracy by measuring an interval between a reticle and a contraction lens as optical distance, and controlling to feed back it by a magnification regulating mechanism, thereby generally correcting the magnification error cause. CONSTITUTION: A laser light from a laser light source 7 is guided through a laser interferometer 6 and the hole 2a of a chuck 2 into an optical column 1. Then, the light is reflected on a lens holding flange 5, fed again through the hole 2a, returned to the interferometer 6, deflected from the interferometer 6 to the horizontal outside, and detected by a detector 8. Thus, an interval between a reticle 3 and a contraction lens 4 is measured as an optical distance. The measured result is fed to a magnification control unit 9, which operates a column elevationally moving mechanism 10 to regulate the distance between the reticle 3 and the lens 4, thereby correcting the magnification of the lens 4. Thus, a high aligning accuracy can be obtained.
