Title: Burner
Inventor: YAMAMOTO KATSUHIKO
IPC: F23D5/02
Filed: 1983-01-19
Abstract: PURPOSE:To positively display the function of puritying the catalyst member even at the time of ignition and extinguishing and perform effective feedback of the exhaust heat to an evaporating member, by positioning the catalyst member in contact with the outer peripheral part of the evaporating body and passing a high temperature exhaust gas through said position. CONSTITUTION:Power is supplied to an electric heater 2 to preheat the evaporating member 1 to a temperature of approximately 300 deg.C. Then, when power is supplied to a blower 16, a pump and an igniter 14, combustion air and fuel are supplied within the evaporating member 1, and the fuel is evaporated to form a premixed gas with air. This pre-mixed gas enters into a rectifying cylinder 4 from the central part of the partition plate 3 and passes through small holes. Then, the pre-mixed gas is injected onto the outer surface of the combustion member 6, and is ignited by the igniter 14 and burnt. Buring flame red-heats the wick of the combustion member 6 formed thinly on the outer surface of the combustion member 6 to above 850 deg.C. The combustion exhaust gas advances from between the combustion member 6 and the outer plate 10 and to between the evaporating member 1 and the guide plate 8, and comes into contact with the catalyst member 12 fixed to the outer peripheral part of the evaporating member 1, and then is exhausted through an exhaust port 9.

IPC: G02B6/44
Filed: 1978-01-26
Abstract: PURPOSE: To facilitate laying of a very long cable within tube by covering the cable with a buoyancy-providing material of a specific gravity lower than that of liquid filling the tube in front of the tube while the cable is being withdrawn.  
     CONSTITUTION: A cable is laid into a tube 3 filled with a liquid 4 while covering the cable 2 with a buoyancy-providing material 7 having a specific gravity lower than that of the liquid, for instance polyethylene and foamed polyethylene, with a covering device 5 provided in front of the tube 3. By covering the cable  with the buoyancy-providing material in this way, the apparent weight of the canle within the liquid is reduced that much to reduce the with drawal tension and thus reduce damage to the cable laid within the long tube.

Title: Apparatus for jetting solder and method of soldering
Inventor: NAKAOKU KIYOTAKA
IPC: B23K1/08
Filed: 1999-01-14
Abstract: PROBLEM TO BE SOLVED: To add a function of preliminary heating, without increasing the size of an apparatus for jetting solder and reduce bridge failures, when using lead-free solder in the apparatus for jetting solder which solders electronic components to an electric circuit board by means of a jet flow of solder. SOLUTION: An apparatus for jetting solder comprises a pressure-reducing device, a feed valve 32, a heater 33, and an outlet 35 for heat flow. The heat flow is fed to an inlet 222 provided at a flange 22 of a local jet jig 20, to blow the heat flow out of a nozzle 221 of the flange, which allows an electric circuit board 2 to be heated efficiently in advance. This allows a means for preliminarily heating to be downsized to add the function of preliminary heat without increasing the size of the apparatus for jetting solder. Also, the use of an inert gas for preliminarily heating allow the oxidation inside the flange to be prevented to decrease bridge failures, when lead-free solder is used.
