Title: Driving method for ink jet print head
Inventor: FUJIMOTO HISAYOSHI
IPC: B41J2/055
Filed: 1992-04-30
Abstract: PURPOSE:To prevent printing from becoming disordered, ink from being mixed with air bubbles, and to improve productivity while making printing in high density obtainable even with a head relatively in low density, and to make furthermore shuttle motion smooth. CONSTITUTION:Printing is made to one printing line on printing paper by a print head 1 for four dots assigned to each of nozzles of the print head 1 by moving the head 1 little by little, each by the distance corresponding to one dot, in one direction of print scanning. After repeating four times the printing to each one printing line in one direction, the printing is made to one printing line for four dots by moving the head 1 little by little, each by the distance corresponding to one dot, in the other direction of the print scanning, and such printing is repeated four times. When the head 1 is returned to a point wherefrom the printing is started, one shuttle motion of the head 1 in the direction of the print scanning is completed.

Title: Heat insulating piping
Inventor: KAKUMAE HIDEO
IPC: F16L11/12
Filed: 1980-08-11
Abstract: PURPOSE: To achieve conservation of energy, by covering at least the upper portion of an outdoor hot-water pipe with a transparent material in keeping heat of hot water in the pipe by use of an heat insulating material.  
     CONSTITUTION: A hot-water pipe 1 is placed in a tubular body 10 and its surface is covered with a transparent glass plate 4 or the like. Holes for draining rain water are formed at the bottom of the tubular body 10, and heat insulating material 7 is filled around the pipe 1 excluding the portion of transparent plate 4. Since, with such an arrangement, solar heat is given to hot water 2 in the pipe 1 through the transparent plate 4, heat of the hot water 2 is conserved and heat is absorbed positively, so that the temperature of the hot water 2 is rather raised. Thus, conservation of heat can be accomplished.
