Title: Heat-accumulating material
Inventor: KOIKE KEIICHI
IPC: C09K5/06
Filed: 1981-03-13
Abstract: PURPOSE: A flame-retardant and lowly corrodible heat-accumulating material for an air conditioner with large heat-accumulating capacity working in a desirable temp. range, which is obtd. by adding sodium acetate, ammonium acetate, potassium acetate or calcium acetate to acetic acid.  
     CONSTITUTION: At least one among sodium, ammonium, potassium and calcium acetates is added to acetic acid. The m.p. of acetic acid depends on its purity. Although, for example, industrial acetic acid of purity 99% has an m.p. of as low as 15°C, even when such acetic acid is used, the degree of m.p. reduction due to addition of sodium, potassium, ammonium or calcium acetate is almost the same as in the case of pure acetic acid. Therefore, when the m.p. of acetic acid to be used is previously determined, it is possible to obtain the m.p. of a mixt. based on the m.p. depression determined from a preliminarily made chart showing variation of the m.p.

CONSTITUTION:The lower end of a water separating pipe 6 is opened at a lower part in a hot-water storing tank 5, and the lower end opening of the pipe 6 is located  at a position spaced away from a collector 4. The upper end of the pipe 6 is disposed  with such an inclination that it is located at the part of the wall (front wall or side  wall) of the tank 5 near the collector 4, and a nozzle 12 formed at the upper end of  the water separating pipe 6 is extended to the outside through the wall of the tank 5.  Further, an air vent pipe 13 is extended upward from a position near the joining part  of the pipe 6 and the nozzle 12. Here, arrangement is such that the gradient of the nozzle 12 is normal in case that the gradient of the roof surface 3 is gentle. Taking it  consideration that the gradient of the roof is in general about 30 deg., the gradient of the  nozzle 12 is normal in case of ordinary roofs. However, even if the gradient of the  roof is steep (30 deg.+beta) and the gradient of the nozzle 12 is reverse resultantly, it is enabled to circulate water while reducing stagnation of air extremely.

Title: Laser soldering method and soldering device used therefor
Inventor: KOMIYAMA KATSUMI
IPC: H05K3/34
Filed: 1984-02-29
Abstract: PURPOSE:To perform soldering with a high grade in short time by taking widely a laser-irradiating area at a soldering point in the initial period of heating then narrowing said irradiating area to increase energy density and heating the soldering point by the laser. CONSTITUTION:An electrode part 2 of an electronic part 1 is disposed on a soldering pattern 4 formed on a printed wiring board 3 and is heated by a laser beam 5 in a method for soldering said part 1 to the board 3 by laser heating. The laser beam 5 is applied to a wide area of the part 1, the electrode 2, the pattern 4, the board 3, etc. by making the beam diameter of said beam relatively large in the initial period of the heating. The inside of the irradiated surface is thus preheated and the fit of soldering is improved while the damage on the board 3 is averted. The irradiating area of the beam 5 is thereafter decreased to perform soldering in the short time at the increased energy density.

Metals, such as stainless steel and Be-Cu alloy, having excellent corrosion resistance and mechanical strength are used for these members. The flexible pipe 9 and the metallic net body 10 which are superposed on each other are eventually not restrained in the hollow pipe 5 and even if these pipe and net body are covered by the metallic pipe 10, the flexible pipe 9 is capable of exhibiting sufficient flexibility and, therefore, the hollow pipe 5 is eventually freely bendable after the flexibility is assured. As a result, the need for the connection by welding is eliminated and the increase of the cost is averted.
