Title: Electronic learning machine
Inventor: KAWAGUCHI TAKESHI
IPC: G06Q50/20
Filed: 1989-05-06
Abstract: PURPOSE:To improve printing efficiency and to eliminate the disturbance in characters in divided positions by providing an empty bit line detecting means, virtual interline detecting means, printing data allotting means and line feed rate adjusting means. CONSTITUTION:This learning machine is constituted by providing the empty bit line detecting means 11, the virtual interline detecting means 12, the printing data allotting means 13, and the like feed rate adjusting means 14. A carriage moving direction and bit line are scanned and the absence of the bits which become black in the printing is detected by the means 11. If the resulted number of the continuous empty bits exceeds a prescribed value, such excess is detected by the means 12. The printing data is allotted by the means 13 in such a manner that the next bit line of the continuous empty bits is printed by the top end dot of a printing head when the virtual interline is detected by the means 12. The line feed by as much as the number of the empty bit lines is executed by the means 14 when this allotting is executed. The printing efficiency is improved in this way and further, the disturbance in the characters in the divided positions generated by the printing executed dividedly twice in the printing of the lines of only the character arrays is obviated.

Abstract: PURPOSE:To facilitate the assembly and adjustment of an optical system by returning a linearly polarized light transmitted through or reflected at a plate polarizing beam splitter to the plate polarizing beam splitter again in rotating a polarizing surface and reflecting or transmitting the light at or through the plate polarizing beam splitter. CONSTITUTION:P polarized components transmitted through two-sheet laminating plate polarizing beam splitter 12 are converted to S polarized components by a second optical system 21 composed of a 1/4 wavelength plate 13 and a reflecting mirror 14, the components are returned to the two-sheet laminating plate polarizing beam splitter 12 again, and they are reflected at the two-sheet plate polarizing beam splitter 12. Consequently, the same result as the case where two sheets of parallel flat plates with the same thickness as the two-sheet laminating plate polarizing beam splitter 12 are inclined at an inclination angle equal in positive and negative reverse directions to an optical axis is obtained, and a coma can be canceled. Thus, since the parallel flat plates as a conventional case can be made unnecessary, the adjustments of the inclinations, thicknesses, etc., of the parallel flat plates can be made unnecessary, and the assembly and adjustment of the optical system can be facilitated.

IPC: H03B5/18
Filed: 1979-09-05
Abstract: PURPOSE:To ensure the steady characteristics over a wide range of frequency with no big change of the coupling degree, by providing a coupler plus the coupling conductor provided in parallel to the central conductor at the end part of the coupler and thus securing the change of frequency. CONSTITUTION:The coupling conductor 21 is provided at the end part of the coupler 18 in order to reduce the change of the coupling degree between the central conductor 13 and the base of the transistor 1 in accordance with the change of length of the conductor 13 which functions to obtain a tuning over a wide band. In this case, the conductor 21 is set in parallel to the conductor 13. The length of the conductor 21 is set longer the variable width of the conductor 13 which is required for tuning in a wide band, at the same time the tip of the conductor 13 is located not so as to cause a shift from the conductor 21 to the change of length of the conductor 13. In such way, no big change is given to the distance between the tip of the conductor 13 having the maximum electric field and the conductor 21 although the length of the conductor 13 may change. As a result, the change of the coupling degree can be reduced, thus securing a tuning of a wide band.
