Title: Solar-heat water heater
Inventor: KITAJIMA SOUICHI
IPC: F24S10/95
Filed: 1981-12-11
Abstract: PURPOSE:To enhance thermal conductance at a part of contact between a condensing  part of a heat pipe and a container, by a method wherein a condensing part of a heat  pipe is covered by a covering container made of a material having a coeffient of  thermal expansion lower than that of a material for the condensing part, and the  container and a hot water storing tank are sealed. CONSTITUTION:The water heater is comprised of a heat collector which consists of  heat-collecting plates and an evaporating part of the heat pipe 1, and the hot water  storing tank 3 which is placed in the direction of an upper part of the heat collector  and through which the condensing part 1a of the heat pipe 1 is passed. The condensing part 1a is covered by the covering container 2 made of a material (e.g., copper) having  a coefficient of thermal expansion lower than that of the material (e.g., Al) for the  part 1a, and the container 2 and the tank 3 are sealed. Initially, an appropriate gap is  present between the container 2 and the condensing part 1a, so that the part 1a can be  easily fitted into or detached from the container 2. On the other hand, when the heat  collector receives sunshine, the temperature of the pipe 1 becomes higher than that of  the container 2, and the part 1a and the container 2 are snugly connected to each other, whereby the thermal conductance can be enhanced, and heat-collecting efficiency can be enhanced.

IPC: H05B41/23
Filed: 1987-08-13
Abstract: PURPOSE: To reduce the power loss by providing an electric discharge lamp lighting circuit with a filament control circuit for controlling the impression of voltage approximately inversely proportional to the level of a control signal to a filament. CONSTITUTION: The lighting circuit is provided with the filament control circuit 9 for controlling the impression of voltage approximately inversely proportional to the level of a control signal to the filament. Namely when the level of control signal inputted to each of switch elements 6 to 8 is high, a large lamp current proportional to the control signal is allowed to flow and the filament 2 is heated by the lamp current itself, so that the circuit 9 impresses voltage inversely proportional to the control signal to the filament 2. When the level of the control signal is low, the circuit 9 impresses a large voltage inversely proportional to the control signal to the filament 2. Consequently, unnecessary filament heating power is cut off and a power loss can be reduced.
