Title: Hot water feeder
Inventor: KUBOYA MASANORI
IPC: F24H1/10
Filed: 1991-12-26
Abstract: PURPOSE:To prevent corrosion in a heater due to dew condensation by a method wherein a normal-closed opening or closing valve at the heat exchanger is arranged at a downstream side of a branch point of a water feeding pipe with a bypassing pipe. CONSTITUTION:A normal-closed opening or closing valve 20 for fully closing or fully opening a flow passage of a water feeding pipe 13 and a flow rate sensor 21 at a heater are arranged at a downstream side of a branch point of a water feeding pipe 13 with a bypassing pipe 15. As water is started to flow in the water feeding pipe 13, the detected value of a total flow rate sensor 18 is compared with the value of 3.5 litter/minute and 3.0 litter/valve. During a period in which the total flow rate is more than 3.5 litter/minute, the opening or closing valve 20 at the heater device is opened. As the opening or closing valve 20 at the heater device is opened, the opening or closing valve 20 at the heater device may not be closed even if the total flow rate is lower than 3.5 litter/minute as long as the total flow rate is not decreased lower than 3.0 litter/minute, so that even if the total flow rate is varied near the value of 3.5 litter/minute, the opening or closing valve 20 at the heater may not be frequently opened or closed.

Filed: 1998-12-21
Abstract: PROBLEM TO BE SOLVED: To properly calculate an optimum shutter speed without saturating pixel data in the case of applying A/D conversion to a camera signal by decreasing a shutter speed in the case of pixel mixed readout. SOLUTION: When a full pixel read system is selected, initial shutter speed data of 1/250 sec are set to a register 23 and pre-exposure is conducted according to the data. A microcomputer 40 calculates an optimum shutter speed on the basis of a camera signal generated by the preliminary exposure and writes corresponding data to the register 23. As a result, normal exposure is executed according to the data. When a pixel mixed readout system is selected, the initial shutter speed at the preliminary exposure is set to 1/500 sec. That is, the shutter speed is halved in comparison with that in the full pixel readout. When a camera signal is generated by the pre-exposure, the optimum shutter speed is obtained similarly to above and the normal exposure is executed according to the data.
