IPC: G07F13/06
Filed: 1994-09-07
Abstract: PURPOSE: To vary the amount of fed hot water through simple constitution at need. CONSTITUTION: A hot water storage tank 22 is provided with a pump 24, which pumps hot water out of the tank 22 and fed the hot water to a mixing bowl 9 through a pipe 25 for hot water.

Title: Image heating device
Inventor: YAMAZAKI MICHIHITO
IPC: H05B3/20
Filed: 1996-09-12
Abstract: PROBLEM TO BE SOLVED: To improve higher harmonic distorsion and flicker by making energizing patterns different between plural heating elements supplying power to plural resistors. SOLUTION: The driving control of triode AC switches(TRIAC) 51 and 52 is performed in accordance with the resistance value of a thermistor 640 inputted to a CPU 100 through electrodes 641 and 642, so that electric power supplied to the heating elements 610 and 620 from a power source 30 is controlled. The energizing patterns of the heating elements 610 and 620 are changed, and one heating element is always made to generate heat, so that the electric power of a heater is increased without increasing a current made to flow through a switching circuit in an operation state. Thus, the electric power of the heater is increased without increasing a higher harmonic current. The resistance values of the heating elements 610 and 620 need not be the same, and the resistance value of the heating element on either of an upstream side or a downstream side may be made higher.  Thus, the energizing pattern is made different between at least two heating elements 610 and 620, so that the higher harmonic current and the flicker are reduced and also temperature ripple is reduced.
