Filed: 1978-03-20
Abstract: PURPOSE: To permit a pressure tank to be effectively utilized by controlling the inlet and outlet of the pressure tank with the operation of a pressure switch to enclose a large amount of air in the pressure tank.  
     CONSTITUTION: While water in a pressure tank 13, when consumed in plenty, is lowered lower than the lower limit L 1  of level to make air 35 flow out through a connection pipe 11, the internal pressure is lowered lower than that P 1  in the lower limit L 1  of level to close a flow path 21 communicating to a driving channel 21 by a diaphragm 27 of the pressure switch 15. Thus the internal pressure in the pressure tank 13 is maintained lower than that the internal pressure P 1  in the lower limit L 1  of level to prevent the effluence of air 35. That  is, a great amount of air 35 can be enclosed in the pressure tank 13 which can be effectively utilized by setting the lower limit L 1  of level to such a position as air does not flow out through the connection pipe 11.

Title: Automatic read address generating system for frame memory
Inventor: OKITSU SHINICHI
IPC: G06F12/02
Filed: 1991-02-02
Abstract: PURPOSE:To arbitrarily control the read leading address of a frame memory for video output. CONSTITUTION:The read leading address for each line of a display picture set on the frame memory is loaded from a loader to an address counter 5 during a horizontal flyback period. The address counter 5 increases/decreases a count value while being synchronized to a read clock RD, and a read address is defined based on this count value. Since the leading address can be arbitrarily set to the loader, the burden of a hardware is reduced and the segmenting or zooming of the display picture can be effectively executed.

Abstract: PURPOSE:To contrive a higher printing speed and a smaller and lighter printer, by providing a plurality of rows of heat generating elements on a substrate, connecting unit signal lines to the heat generating elements in each of the rows, and providing a common signal line for each of the heat generating element rows. CONSTITUTION:In a thermal head for a printer, for example, two heat generating element rows 5, 10 comprising plural heat generating elements 4, 9 are provided on a substrate 1. Further, unit signal lines 6 are connected respectively to the corresponding heat generating elements 4, 9 in the rows, and common signal lines 7, 11 are respectively connected in parallel with hthe heat generating elements in each of the rows. At an intersection of the common signal line 11 and the unit signal line 6, the signal lines are laminated with each other through an insulating layer 8 therebetween. During energization of some of the heat generating elements in one of the rows, the heat generating elements in the other row are cooled, so that a relative velocity of the head can be enhanced. Since the heat generating elements in each of the rows can be independently controlled by grouping the unit signal lines into a single system while sequentially making the common signal lines effective, the total number of the signal lines can be markedly reduced.
