Title: Maximum power point follow-up device and solar thermal power generation system using the follow-up device
Inventor: TOYOURA NOBUYUKI
IPC: H02J7/35
Filed: 1995-09-25
Abstract: PROBLEM TO BE SOLVED: To accurately retrieve a maximum power point without reducing efficiency even when the output characteristics of a solar battery are largely changed by determining a direction of change of the output voltage of the solar battery based upon a change in generation power when output voltage is changed and a change in the generation power when the change of the output voltage is stopped for a fixed period. SOLUTION: A control means determines a direction for changing the output voltage of the solar battery based upon a change in generation power when the output voltage is changed and a change in the generation power when the change of the output voltage is stopped for a fixed period. Namely a change ΔAC in the generation power when the output voltage is changed to ΔV and generation power ΔPC due to an environmental change such as an illuminance change for a fixed period when the change of the output voltage is stopped are measured. Power variation removed with power variation due to the environmental change is calculated by subtracting the ΔPCD from the ΔPAC and optimum operation voltage is retrieved based upon the calculated power variation.

Title: Refrigerant flow diverter
Inventor: SUGA HIROAKI
IPC: F16L41/08
Filed: 1987-09-30
Abstract: PURPOSE: To reduce fluctuation of performance in flow distribution by a method wherein both ends of a substantial U-shaped pipe are constituted by a bent section which is substantially at right angles against a substantial U-shaped pipe with both the ends being bent in the same direction and a projecting pipe extended from a part near the central part of the substantial U-shaped pipe and protruded in parallel with the bent section. CONSTITUTION: Bent sections 11 are bent at a substantial right angle in respect to a substantial U-shaped pipe 10 and in the same direction. A protrusion pipe 12 is made by pushing out a pipe from a location near the central part of the substantial U-shaped pipe 10 in parallel with the bent sections 11. The ends of the bent sections 11 and the protrusion pipe 12 are inserted into some heat transfer pipes of a heat exchanger and the refrigerant may flow from the protrusion pipe 12 toward the bent sections 11. In the case that the protrusion pipe 12 is formed, lead 14 is enclosed in a straight pipe 10' in the same manner as that of the prior art and then it is pressurized at both ends of the straight pipe 10'. Then, the protrusion pipe 12 is pushed out of a location near the central part of the straight pipe 10'.  After this operation, the end part of the protrusion pipe 12 is cut to form a shape as shown in the figure and then the lead is melted. Owing to this fact, the length L2 of the protrusion pipe 12 can be made short, no protrusion part is formed at the inner surface of the pipe, and hence, fluctuation of distribution performance of the flow can be reduced.

The current loop has a proportion con trol system or another control system which is approximated to the proportion control and at the same time the velocity loop has an I-P control system and a secondary system. The velocity loop having the desired control characteristic is defined as a standard loop. Then a proper angle frequency omegan and an attenua tion constant zeta are set for describing the operation of the standard velocity loop. The integration time of the velocity loop is adjusted to 2zeta/omegan together with the general proportion gain adjusted to 2zetaomeganJe, respectively. Thus, the desired control characteristic is obtained with no variance and no oscillation of an industrial system.
