Patent number: 5769308Abstract: The composition of a hard-facing welding material to be overlaid onto a cast iron base metal followed by a supercooling treatment for hardening must lie above a line LA in a Schaeffler's structure diagram which is represented by a Cr equivalent and a Ni equivalent. On the other hand, if the base metal is preheated, the carbon precipitation line will be at the Ni equivalent of 34 (LC1), and the Cr equivalent will thus be above 4. However, if the Cr equivalent is above 4, there will occur cracks after welding (examples in which cracks occurred are shown by square marks represented by a in FIG. 1). As a solution, the carbon precipitation line was raised up to the Ni equivalent of 38 without preheating the base metal, and the Cr equivalent of the welding material was made to be 4 or less.Type: GrantFiled: December 23, 1996Date of Patent: June 23, 1998Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Tsuyoshi Kokusho, Keizou Tanaka, Hideaki Ikeda, Masanobu Ishikawa, Hideo Nakamura, Shigeru Ohno, Masami Watanabe

Patent number: 5521621Abstract: A recording apparatus comprises an inlet for accepting a liquid to be delivered to an outlet orifice through a liquid flow path. Liquid is supplied to the inlet for flow through the liquid flow path to a heating element, which heats liquid in the liquid flow path. Heating is sufficient to cause a change of state of the liquid (that is, to generate a bubble) and produce a force acting on the liquid which overcomes the surface tension of liquid at the orifice and thereby projects a droplet of liquid from the orifice. The temperature of the heating element is raised at each actuation to a temperature above the maximum temperature at which the liquid in the liquid flow path is subjected only to nucleate boiling so as to promote substantially instantaneous transfer of heat to the liquid proximate to the heating element and to retard the transfer of heat from the heating element to liquid at other locations in the liquid flow path.Type: GrantFiled: January 12, 1994Date of Patent: May 28, 1996Assignee: Canon Kabushiki KaishaInventors: Ichiro Endo, Yasushi Sato, Seiji Saito, Takashi Nakagiri, Shigeru Ohno
