Title: Solar heat water heater
Inventor: KITAJIMA SOUICHI
IPC: F24S10/95
Filed: 1983-01-20
Abstract: PURPOSE:To prevent a dry-out phenomenon and bumping and contrive to enhance heat-conveying performance, by providing a return pipe between a heat- collecting plate provided at an evaporating part and a bottom surface of a collector. CONSTITUTION:Solar rays transmit through a light-transmitting body 6a provided on the front face of a collector 6, and are absorbed by the heat-collecting plate 9 at the evaporating part 11. The light absorbed is converted into thermal energy, which is transmitted to heat-collecting pipes 10 to boil and evaporate a working fluid 18 contained in the pipes 10, whereby it is removed as latent heat of evaporation,and bubbles 19 are generated. When the solar radiation quantity is small or the temperature of a condensing part 14 is high, a circulating force of the fluid 18 becomes weak, and when the bubbles generated in the return pipe 16 provided in the collector 6 grow to have a large buoyancy, the circulating force may be canceled with the result that a normal circulating operation is hindered. However, since the return pipe 16 is provided between the evaporating part 11 and the lower surface 17 of the collector 6, solar heat is shielded by the heat-collecting plate 9, and the return pipe 16 is not heated, so that generation of bubbles in the return pipe 16 is prevented from occurring. Accordingly, the working fluid 18 is circulated normally, the dry-out phenomenon and bumping can be prevented from occurring, and a high heat-conveying performance can be secured.

The height of potential barriers in I-type Al0.3Ga0.7As layers 8a and 8b is higher than that of a potential barrier in the layer 5 due to a difference between the compositional ratios of Al in the layers 8a and 8b and the layer 5, an electron confinement effect is increased and a gm is increased.

IPC: H01S3/097
Filed: 1999-01-14
Abstract: PROBLEM TO BE SOLVED: To elongate power supply units in service life so as to improve a laser oscillator in reliability. SOLUTION: Optical power commands outputted from a control device 15 are converted into power commands, and the power commands are inputted into power supply units 3A to 3C. The power supply commands given to the power supply units 3A to 3C are divided by output currents through the DC units into voltage commands, and output voltages amplified proportional to the voltage commands are outputted to high-frequency power supplies 19A to 19C. Therefore, output powers nearly uniform in magnitude are outputted from the high-frequency power supplies to an oscillation head 5 based on the above output voltages and the output currents. Therefore, even if the partial regions of an electrode 7 corresponding to the power supply units 3A to 3C are different from each other in output current, the power supply units 3A to 3C become nearly equal to each other in power consumption.  As a result, the power supply units 3A to 3C become nearly equal to one another in service life to improve a laser oscillator in reliability.
