Inventor: KAKU TAKESHI
IPC: F22B37/10
Filed: 2001-07-06
Abstract: PROBLEM TO BE SOLVED: To provide a superheated steam generator which efficiently generates well superheated steam. SOLUTION: The superheated steam generator comprises; a saturated steam generating part 2 for generating saturated steam 17 by boiling water W by high frequency induction heating; and a superheated steam generating part 3 for generating superheated steam 25 by further heating the saturated steam 17. A high frequency induction heating coil 12 is wound around the outer peripheral surface of the part 2 to constitute a metallic double pipe and define a water storage and evaporating part between the pipes. The saturated steam 17 is directed to the part 3 by a conduction pipe 18 disposed inside the double pipe.  The part 3 comprises a metallic pipe 20 whose peripheral surface is wound around by a high frequency induction heating coil 22, and a core pipe 24 which is inserted into the pipe 20 so as to define a space 23 between itself and the inner surface of the pipe 20 with a given distance being kept therebetween. The space 23 serves as a heating part 23 for the saturated steam 17. Specifically, the saturated steam 17 is transferred to the heating part 23 through holes 24b formed on the core pipe 24 to generate superheated steam.

IPC: B23K1/08
Filed: 2001-07-06
Abstract: PROBLEM TO BE SOLVED: To provide a jet type soldering device which can solve the problem that the conventional jet type soldering device is not provided with means for coping with an increase and decrease in quantity of solder in a solder bath and a change in viscosity of solder caused by oxidation and, when the device uses lead-free solder having lower wettability, the productivity of the device declines, because many defective products are produced. SOLUTION: The height jet stream of a jet solder flow from the jet type soldering device 1 is controlled to a fixed value by means of the output of a jet stream pressure detecting sensor 6 provided correspondingly to the position where the solder jetting is performed. Consequently, even when the lead-free solder the height of jet stream of which changes depending upon hourly changing various conditions and which makes the occurring probability of defective products higher due to its lower wettability is used, the height of jet stream of the solder can always be fixed by detecting the jet stream pressure of the solder by means of the sensor 6 in real time.

Filed: 2001-07-16
Abstract: PROBLEM TO BE SOLVED: To achieve a position detecting system capable of accurately detecting a car position in the entire speed range without using crossed induction lines, in a magnetic-levitation railway of a ground primary system. SOLUTION: In the position detecting system 10, a wheel rotational position and speed detecting part 12 detects the car position from a wheel rotational pulse-count value Kw proportional to the revolutions of a wheel 67.
