Title: Solder tank
Inventor: TAKAHASHI SEIHACHI
IPC: H05K3/34
Filed: 1983-06-07
Abstract: PURPOSE:To perform satisfactory soldering even if molten solder is blown up or is held static by providing a projection to prevent backflow of the molten solder to a part of a passage in a chamber and providing an air introducing hole near the top of the projection. CONSTITUTION:The molten solder in a chamber 2 on a blow-off port 7 side is dammed up by a barrier wall 13 as an air well is generated in the top of a projection 12 by the air entering the same through an air introducing hole 15, by which the backflow of the molten solder to a less taller suction port 6 side from the port 7 side is prevented. The fall of the molten solder level on the port 7 side from the port 7 is obviated and therefore even in the static state, soldering on a printed board is made possible.

Filed: 1979-08-10
Abstract: PURPOSE: To obtain tempered glass having high surface smoothness by heating surface-polished glass under specified conditions, carrying out ion exchange treatment, and forming a metallic film on the ion exchanged surface.  
     CONSTITUTION: Glass is mirror-finished by polishing so that flaws remaining on the surface are reduced to ≤10μ in size, and it is heated to a temp. (400W470°C) below the softening point at 10W100°C/sec heating rate and heat treated at the temp. for a fixed time. This glass is then dipped in KNO 3  molten salt or KNO 3 - AgNO 3  molten salt of a predetermined temp. to carry out ion exchange treatment, and a metallic layer of Cr, Al, Cu, MgF 2  or the like is formed on the ion  exchanged glass surface by vapor deposition, sputtering, spraying or other method. Thus, the flaws on the glass surface are diminished, the reflectance of the glass and the adhesion of the metallic film are enhanced, and the occurrence of thermal impact breaking can be decreased.

Title: Optical semiconductor element, optical semiconductor device and manufacture of the optical semiconductor element
Inventor: TOYAMA MASAKI
IPC: G02F1/025
Filed: 1998-04-14
Abstract: PROBLEM TO BE SOLVED: To improve the coupling efficiency of a guided light to an optical fiber by providing notches near the emission end face, except for the extension of a light guide layer. SOLUTION: A pair of notches 14 are provided with a spacing of 15 μm, at the emission end face, except of the extension of a light guide layer 2. The notches 14 at the emission end face reflect down most of the unguided light from a modulator region 16 and reflect upward most of the reflected light from a lens 19 at element end faces. As a result, unguided light components and reflected light components are hardly contained in an optical fiber-coupled light. No notch is provided over a width of 15 μm on the extension of the light-absorbing layer 2, the guided light component spreads only up to about 10 μm during propagating a window region 15 of 10 μm length and the notches 14 do not impedes the guide light from propagating and hence the coupling efficiency of the guided light to the optical fiber can be improved.

Next, this composite material is heated by heat treatment unit 4. As a result, stronger interatomic bonding dependent upon diffusion of metallic ions through contact faces of base metals to one another progresses, so that the composite material having a mechanical property equivalent to ordinary materials can be obtained.

IPC: H04N19/85
Filed: 1993-04-28
Abstract: PURPOSE:To effectively generate an error-correcting signal by dividing a digital video signal into bits on the significant side and bits on the insignificant side, increasing a code amount at an outer parity at the bits, on the significant side, which are e.g. visually important and reducing the code amount at the bits, on the insignificant side, which are not important as compared with the bits on the significant side. CONSTITUTION:When digital data on a video signal and an aural signal is transmitted, the video signal which is composed of, e.g. eight bits is divided into four bits on the significant side and four bits on the insignificant side and an outer parity and an inner parity which correspond to each data part are added to the four bits on the significant side by using a correction-adding circuit which is not indicated in the figure. In addition, an outer parity and an inner parity are added to the four bits on the insignificant side in the same manner by using another correction-adding circuit. At this time, when the four bits on the significant side are data which is, e.g. visually important, a code amount at the outer parity is increased, and the outer parity in a small code amount is added to the four bits, on the insignificant side, which are not important.

Abstract: PURPOSE:To generate a small-sized laser having a high output by arranging a waveguide onto the same circumference. CONSTITUTION:Electrodes 1, 2 are installed to the central section and the circumferential section. Five or fifteen waveguides 3 are formed on the circumference. Partition walls 4 constituting the waveguides 3 are shaped by an alumina sinter, the insides of the waveguides 3 are filled with a gas such as CO2 gas, He gas, N2 gas, etc., on a carbon dioxide laser, reflecting mirrors 6, 7 are mounted oppositely at both ends of the waveguides 3, and a partial-transmitting mirror having reflectivity of 95% is used as one reflecting mirror 6, and functions as a partial-transmitting window in combination. Lasers generated in the waveguides 3 are applied to the outside from the partial-transmitting window, and focussed at a fixed position by a lens 8. Consequently, the phase of output beams from each wave-guide type laser is changed into in-phase, thus focussing laser beams from respective waveguide extremely easily. Accordingly, a device can be miniaturized and a coherent optical output can be acquired.
