Title: Solar heat utilizing hot water supply system
Inventor: MIYOSHI AYATERU
IPC: F24S90/00
Filed: 1983-12-26
Abstract: PURPOSE:To reduce the number of operations of an auxiliary heat source part and improve the economical effect of the sun by connecting a solar heat heat-exchange part and an auxiliary heat source heat exchanger which are connected in parallel, to a hot water storage tank through a four-way valve. CONSTITUTION:A solar heat exchanger 12 and an auxiliary heat source apparatus heat exchanger 17 are connected to the outlet port 18 provided at a lower part hot water storage tank in parallel by way of a circulation pump 11. A four-way valve 13 can be changed over to any of (a), (b), (c) and (d) points. The point (a) represents a boil-up by solar heat. First, the upper part of water is boiled up, and the daytime hot water supply quantity is promptly secured, and then the valve is switched to the point (b) to boil up uniformly the entire part of water. When the additional burning is required, the valve is switched to secure the quantity of hot water at the upper part. Subsequently, the valve is switched to the point (d) to boil up the entire part of water. At nighttime when the hot water quantity is in short, the valve is returned to (c), and hot water at the upper part is boiled up early. As a result, the auxiliary heat source part 2 reduces its number of operation. Further, the auxiliary heat source part 2 can boil up and store hot water in a considerably long time, and can be constituted of a heater 16 of a low output.

Title: Welding method, and its equipment
Inventor: INOUE KOBO
IPC: B23K9/32
Filed: 1996-09-04
Abstract: PROBLEM TO BE SOLVED: To reduce the residual stress in a weld zone by performing the welding with each end of a material to be welded in a restricted condition while the oscillation is given thereto. SOLUTION: Each end of materials 1, 1 is welded in a restricted manner in a hollow part 2a of a restrictive jig 2 of hollow rectangular parallelopiped shape. The restrictive jig 2 is oscillated while a part 8 to be welded of the material 1 is welded. The molten metal at the part 8 to be welded is stirred by the oscillation, and the gas such as hydrogen which may cause blow holes is emitted. Adhesion of scattering spatters to material 1 is prevented by the oscillation. Because the part 8 to be welded is solidified while it is plastically deformed under oscillation, the residual stress and welding distortion can be reduced.  The acceleration and amplitude of the oscillation of the part 8 to be welded are detected by an oscillation detector 18, and a control device controls the moving speed of a welding torch and the delivering speed of a wire for welding so that the welding is appropriate. Slag of the part 8 to be welded is naturally separated by the oscillation.
