IPC: B43L13/00
Filed: 1985-02-27
Abstract: PURPOSE:To enable documents containing graphs, figures and ordinary characters in mixed arrangement to be easily printed by providing X-Y plotting means which relatively moves against a printing medium. CONSTITUTION:If print information containing only the printed portion of graphs, etc. is input to an interface part 14, an LF motor 18 turns normally and reverses to transport printing paper 3 in arrow directions A, B and a space motor 9 is driven to shift an ink jet head 10a in arrow directions C,D. This results in the driving of a nozzle 12b for X-Y plot to print graphs, etc. Next, print information for characters is input to the interface part 14 and identified by a command decoding part 15. After this process, the LF motor 18 is driven to set back the printing paper 3 to a prearranged position and the space motor 9 and a printing nozzle 12a are driven to perform the printing.

Title: Rotary heat exchanger
Inventor: TAKADA SHIYUUICHI
IPC: F28D15/02
Filed: 1982-03-12
Abstract: PURPOSE:To improve the latent heat recovery efficiency of waste heat by providing a heat pipe group rotor exposed at the ends of primary and secondary fluid passages and constructing to inject and supply secondary fluid to the outer surface of the heat pipe in the secondary fluid passage. CONSTITUTION:Primary fluid A is supplied to a primary fluid 17, and is exhausted to an outlet 14. In the meantime, the fluid is contacted with a heat pipe 5 and fins 4 disposed in a turbine blade shape, and radiates heat to the end 5' of the heat pipe 5 while rotating the fins. The heat pipe 5 transfers the heat to the secondary fluid 17' and the side end 5''. At this time, secondary fluid B is scattered to the end 5''. of the heat pipe 5. Accordingly, it radiates heat to the secondary fluid B. In this manner, since the heat pipe 5 is rotated by the fluid A, the cntact is improved, and the heat transfer rate can be improved. Further, even if fluid leakage occurs at the seals 6, 13, direct contact of both fluids is not produced, thereby simplifying the structure of the sealing structure.

Filed: 1983-03-10
Abstract: PURPOSE:To suppress occurrence of the doming of a shadow mask at the early stage of its operation, by adapting the slit holes in the shadow mask to be distributed with specific pitches in the horizontal direction. CONSTITUTION:If the pitches of the slit holes in the shadow mask in the horizontal direction are represented by PO at the center, PH at the end of the horizontal axis, PV at the end of the vertical axis, and PD at the end of the diagonal line, they were adapted to suffice PO<PV<PH and PV<PD, and the pitches between these points were adapted to change smoothly. By such design, the contour of the screen can be made substantially rectangular, and, further, the radius of curvature, R, of the mask can be made smaller in each of vertical and horizontal directions. Thus, the amount of the doming of the shadow mask at the early stage of its operation is decreased and color purity is greatly improved.
