Title: Purification or organic nonlinear optical material bearing hydrogen bonds
Inventor: TOUGAKI YOSHIYUKI
IPC: C07C229/18
Filed: 1987-03-24
Abstract: PURPOSE:To purify an organic nonlinear optical material of high sensitivity to heat deterioration and a high dipole moment by using convection caused by partial heating of the aqueous solution. CONSTITUTION:A hydrogen-bonded organic nonlinear optical material such as 2-methyl-4-nitroaniline, urea or methyl (2,4-dinitrophenyl)-aminopropanoate is recrystallized twice from ethanol. The sample 5 is charged from the inlet 2 into the pyrex glass tube 7 and partial heating is effected with the heaters 3, 4, as a solvent or water is introduced from the inlet 1. Thus, convection takes place in the solution and the sample can be purified by preventing the undissolved and fine sample powder from coming into the purified sample. The product obtained by the process forms no blackened products in the vapor- phase growth operation and the polycrystal product keeps pale yellow.

Filed: 1992-02-21
Abstract: PURPOSE:To manufacture with a good reproducibility a ridge type semiconductor laser excelling in its laser characteristic and reliability. CONSTITUTION:Ge is used as an etching stopper layer 105. AlGaAs can be etched by an etchant (HCl), and Ge is largely resistant to the etchant (HCl). Therefore, a part of a second upper clad layer 106 made of AlGaAs is etched by the etchant (HCl) until reaching the etching stopper layer 105, and a ridge 110 is formed. Thereby, no oxide exists on the etching stopper layer, since no etching stop is performed by an oxidation, and the crystalline defects caused by oxides can be prevented from being generated in a renewedly growing layer.

IPC: H04N7/14
Filed: 1989-03-24
Abstract: PURPOSE:To always receive a correct picture by setting a transmitted signal at a specific format, are preventing the inversion of black and white from being generated in a received picture when a telephone line is used to realize a picture telephone set. CONSTITUTION:The signal format of the transmission of picture data is based on a TTC standard, and signals DLTN to Sm are possessed in periods from T1 to T6. By a signal picture element datum, the 1/2 cycle of a carrier signal S3 (unmodulated signal Sm) is amplitude-converted to obtain the converted signal Sm, and the data indicating the reference direct current level of an amplitude is inserted to the signal Sm. Consequently even when the phase of the reproduced carrier signal S3 is inverted, the black/white of the received picture is not inverted. Thus when the still picture is transmitted through the telephone line, the correct picture can be always received.

Abstract: PROBLEM TO BE SOLVED: To reduce the amount of eddy current loss in the vicinity of the back gap and to obtain a good magnetic reproducing characteristic by providing the front and back section butting surfaces, in which the metal magnetic film of a pair of magnetic core half bodies is divided in the front and back direction at a recessed section, and arranging the pair of magnetic core half bodies so that one of the back section butting surfaces and the other back section butting surface are faced to each other through an insulating body. SOLUTION: A metal magnetic film 6 has the butting surface of the exposed front and back sections which are divided in the front and back directions at the joining surface of magnetic core half bodies 2 and 3. A magnetic gap is constructed by butting two front section butting surfaces through a gap material G. Moreover, two back section butting surfaces are separated and butted to constitute a back gap. When a prescribed magnetic flux flows in the magnetic core during a recording and a reproducing, the flux flows in the back gap through an air layer. Since the layer is electrically nonconductive, no eddy current is generated in the back gap caused by the flux.
