Title: Vapor phase soldering device
Inventor: SOTONO KAZUO
IPC: B23K1/015
Filed: 1988-01-29
Abstract: PURPOSE:To restrain the descent of a saturated vapor phase level and to keep the ascent level of a vapor phase highly enough by providing a perforated plate on the upper face opening of a vapor recovery pocket. CONSTITUTION:The vapor and mist 144 overflowing vapor rise plates 41, 42 fall on perforated plates 54, 55 by its gravity and come into the inner part of pockets 51, 52 through a small hole 56. They are liquefied by getting into contact with the low temp. inert liquid fed from a cooling coil 53 or pipe lines 124, 127 inside the pockets 51, 52. The vapor and mist dropped into the pockets 51, 52 cannot be ascended again by the porous plates 54, 55. The vapor and mist which are made to leak out to the external part via a work carry-in port part 14 or carry-out port part 15 are condensed by cooling coils 16, 18 and the inert liquid liquefied falls into the pocket 51, 52 by descending the slope of the work carry-in and out port parts 14, 15. In that case, the re-ascent of the vapor and mist fed from the small hole 56 is prevented because the cooled inert liquid passes the small hole 56 of the porous plates 54, 55.

Title: Frequency stabilizing device of laser
Inventor: AKATSUKA HIROSHI
IPC: H01S3/139
Filed: 1989-01-31
Abstract: PURPOSE:To obtain excellent stability by introducing laser light into a Fabry- Perot resonator by supplying phase modulation to the laser light and performing feed back as well so that a resonance length can be stabilized. CONSTITUTION:A resonance length stabilization part increases its sensitivity to the resonance length by utilizing interference light waves caused by two sets of resonators 9-1 and 9-2 and its part forms an independent control part and then, control is performed by a filter 1 7-2, a high tension amp. 19-2 and a piezoelectric element 3-2. When a laser angular frequency agrees with the center frequency omegac of a Fabry-Perot resonator, a reflected light spectrum is obtained as shown in figure on referring to reflection characteristics of the Fabry-Perot resonator 9 shown in figure. If negative feedback control is performed by using this reference, laser frequency is stabilized and it is expected that the stability of laser frequency becomes some orders better. This approach renders the stability of oscillation frequency better without requiring any mechanism for stabilizing output power.
