Abstract: PURPOSE: To improve to a great extent the rate of heat transfer from the inner surface of a heat receiving pipe to a coolant, by forming layer of a porous material on the inner surface of a heating pipe in the captioned solar heat collector.  
     CONSTITUTION: In a solar heat collector 10, a layer 11 of a porous material is formed on the inner surface of a heating pupe 10b. Accordingly, in a boiling heat transfer operation, a plurality of cavities in the layer 11  of a porous material serve as effective cores for the generation of bubbles, so that a far larger number of bubbles are generated than in a heating pipe having no layer of a porous material on the inner surface thereof. As a result, the coolant-disturbing effect of the bubbles, and the latent heat effect of the coolant being shifted from a liquid phase to a gaseous phase are increased, and the heat transfer rate of the heating pipe 10b is increased. First, a single or a plurality of layers of particles 14 of an arbitrary shape are formed on a flat heating base 13. Then, a metallic film 15 of copper is formed on the surfaces of the particles 14 to fix the particles 14 on the heating base 13. The resulting particles 14 and metallic film 15 form the layer 11 of a porous material. The heating base 13 on which the layer 11 of a porous material has been formed is then bent to a cylindrical shape to form the above-mentioned heating pipe 10b.

Abstract: PURPOSE:To cut down the number of components and to economize and miniaturize a unit by serving a switching element as a reverse circuit concurrently. CONSTITUTION:The base current of a main transistor 1 is turned ON and OFF by a third transistor 8. The base circuit of the main transistor 1 is connected to the collector of the third transistor 8, to the base of which a base resistance 4 of a second transistor 2 is connected. On the other, to the emitter thereof, a resistance 3 is connected which limits the base current of a main transistor l. When the main transistor 1 is cut off, the second transistor 2 shorts across the base and emitter of the main transistor 1, releasing the accumulated charge and cutting off the collector current of the main transistor 1 in an instant. As the base of the third transistor 8 is connected to the collector of a switching element 5, the switching element 5 serves as a reverse circuit concurrently.

Abstract: PURPOSE:To perform synchronism detection easily and save cost and space by clearing a 4-bit binary counter which measures pulse width with reproduced clock precision, and extracting the low-order three bits of the 4-bit binary counter through an AND gate when the low-order three bits are (1,1,1) and obtaining a synchronizing signal. CONSTITUTION:Reproduced data is inputted to a clock reproducing circuit 20 and pulses synchronizing with leading and trailing edges of pulses are generated from the reproduced data to generate a reproduced clock D. The reproduced data A and its delayed reproduced data B are passed through an EX-OR22 to generate a narrow pulse C synchronizing with the leading and trailing edges of the reproduced data A, thereby clearing the binary counter 23 for pulse width measurement with the pulse. Then, 1110 is obtained as outputs QA, QB, QC and QD of the binary counter 23 for pulse width measurement unless the next clear pulse C arrives for a period of eight pulses, so those QA, QB and QC are extracted through a 3-input AND gate 24 to obtain the synchronizing signal E.
