Title: Reflowing method of flexible printed board
Inventor: TAKANO HIROSHI
IPC: H05K3/34
Filed: 1990-03-13
Abstract: PURPOSE:To dispense with holes bored in a flexible board for engaging it with a carrier so as to simplify an operation and to heat all the flexible board uniformly to enable cream solder to be easily printed by a method wherein the end of the flexible board is pasted onto a metal plate, cream solder is applied onto the board through printing, and the board is heated in a reflow oven to solder electronic components to the board. CONSTITUTION:A flexible board F is placed on a metal plate 10, and both the ends of the board F are pasted onto the metal plate 10 with a single sided tape 11 from above. The single sided tape is a tape provided with a heat resistant adhesive layer on one side. A mask (not shown in a figure) is laid on the flexible board H pasted down on the metal plate 10, cream solder is put thereon, and then the cream solder is printed by moving a squeegee. Electronic components are placed on the board F where cream solder is printed, which is heated in a reflow oven to make cream solder reflow. After a reflowing process is finished, the single sided tape is separated off from the board F to dismount it from the metal plate 10. As mentioned above, a thin flexible board becomes uniform in temperature as a whole when it is indirectly heated by the heat of a metal plate, and a recent adhesive agent is excellent in heat resistance and can be used many times.

Title: Water heater utilizing solar heat
Inventor: KATOU MASAO
IPC: F24S10/95
Filed: 1984-03-27
Abstract: PURPOSE:To solve the ''blue water'' problem or the adhesion of insoluble blue substance by a method wherein a metal, the ionization tendency of which is larger than that of the metal composing a heat exchange part, is abutted against and mounted to the heat exchange part by means of an elastic clamping wire. CONSTITUTION:Grooves 5c are made by cutting a metal rod, the ionization tendency of which is larger than that of the metal composing a heat exchange part 4, or for example, a magnesium rod having a steel core or the like 5b, at two positions down to portions having a diameter a little smaller than the outer diameter of the rod 5a. The grooves 5c are for positioning when the rod 5a is mounted and for improving the electrical contacting state between the rod 5a and the heat exchange part 4. A clamping wire 5l is made of stainless steel wire of the like and worked into V-shape and made springy. In order to mount, the clamping wire 5l is at first hung on the pipe of the center heat exchange part among three heat exchange parts 4 and secondly, two magnesium rods 5a are placed onto the three heat exchange parts 4 so as to intersect crosswise one another and finally both the tips of the clamp wire 5l are hooked to the heat exchange parts at both sides among the three heat exchange parts 4 in order to fix the rods 5a. Under the state as just mentioned above, the clamping wire 5l and the heat exchange parts 4 intersect one another. Because the metal having the larger ionization tendency than that of copper elutes positively and consequently the elution of copper is suppressed, no ''blue water'' problem occurs.
