Abstract: PURPOSE: To enable two-color type printing without enlarging the size of a device, by arranging the mask which will cover one of two different color type rings, and shifting the relative positions of the type rings along a type printing direction, in a serial printer.  
     CONSTITUTION: The red part R of a mark type ring 1 is covered with a mask 6 at first, so as to print a black mark onto a blank sheet 7 by the operation of a hammering part 4. A spacer hammer 19, synchronized with the operation, rotates a spacer 16 and inserts it into a space between a type ring support 9 and a mask support 10. Consequently, a numeral type ring 2 moves to the position that its red part R faces to the mask 8. As a result, the type printing operation using the black side B is continued. In case of red type printing, a signal is fed to a plunger 11 before a mark is printed, to carry the type ring support 9 by one reed. Consequently, there is not any space into which the spacer 16 would be inserted, so that the masks 6, 8 face to the black side B. As a result, the type printing operation using the red side R is performed.

Title: Majority logical system
Inventor: TASHIRO FUSASHI
IPC: H03K19/007
Filed: 1984-03-26
Abstract: PURPOSE:To foreknow abnormalities containing an input, too, in a fail-safe majority logic, by executing a prescribed arithmetic between frequency values of an input alternating signal, and identifying and displaying an input for showing a truth value which is different from an input truth value for satisfying a majority logic. CONSTITUTION:Input signals 4, 5 and 70 correspond to the first, the second and the third channels, respectively. When logical values ''1'', ''0'' of each channel are shown by frequencies which are slightly different, the frequency of an addition result signal 14 generates no repetition in all combinations of 14 pieces when a different input is less than one. Accordingly, by providing at least 15 pieces of time slots for deciding a frequency band, all the combinations of these addition results are identified and an output logical value can be determined. A fall timing of a deciding signal 36 shows this identification result, therefore, a faulty channel detecting circuit 78 samples the signal 36 by using a timing signal group 80, and when an abnormal channel is generated, an output is generated to one of the channel fault display terminals concerned 81-83.
