Title: Wavelength division type solar battery
Inventor: UMENO MASAYOSHI
IPC: H01L31/077
Filed: 1980-03-31
Abstract: PURPOSE:To improve the conversion efficiency of a solar battery by growing two or more semiconductor thin film crystals having different band gap energy on the same substrate, forming a p-n junction in the crystals, thereby dividing the wavelength of the solar light and converting it into electric power. CONSTITUTION:Two or more semiconductor thin film crystals 4, 5 having different band gap energy are grown on the same substrate 6. An InP is, for example, used as the substrate 6, and InGaAsP layer and an InP layer are used as the crystals 5, 4. The band gap energy Eg1 of the crystal 4 is increased larger than the Eg2 of the crystal 5, and thus it operates as wavelength division type solar battery. Then, the hole and electron pair thus generated and isolated by the p-n junction surface 7 are produced as electric power. Thus, the wavelength of the solar light is divided and converted into electric power, thereby improving the conversion efficiency.

Abstract: PURPOSE:To enable interference fringes with a high contrast to be obtained by providing first optical means for directing light beams split by light beam splitting means to a diffraction grating and second optical means for superposing diffracted light beams of different order emitted from the diffraction grating and detecting the moving condition of the grating with the signals from light receiving means. CONSTITUTION:Two light beams split by a light beam splitter 13 are projected upon light receiving means 15 and 17 via polarizing plates 14 and 16, respectively, arranged with polarization bearings inclined by 45 degrees relative to each other as linearly polarized light beams with the phase differences of 90 degrees relative to the two light beams. In this case, the light beam emitted from a laser 1 is split into transmitted and reflected light beams at a prescribed intensity ratio by the light beam splitting plane 4 of an optical part 3. Since the intensity ratio of the light beam of a wave P to the light beam of a wave S split by the light beam splitting plane 4 is represented by sin<2>theta: cos<2>theta, by so setting the ratio in advance that the intensity ratios of the two diffracted light beams of different orders which are diffracted by a diffraction grating and to be finally superposed are equal to each other, interference fringes can be formed by the light beams with the same amplitude and a high contrast can be obtained.

Abstract: PURPOSE:To prevent quantized noise from being increased even if two systems using different coding methods are connected in tandem by coding the result of the 2nd decoding system for the result of coding/decoding of the 1st coding system for an input signal by the 1st coding system again. CONSTITUTION:A signal PCM-coded is inputted from a terminal 1, an ADPCM code is outputted from a terminal 2 and inputted to a terminal 3 via a line and decoded. This decoded signal is outputted from a terminal 4 as a PCM code again. The inputted PCM code becomes a linear code by a PCM decoder 100 and applied to an ADPCM coder 200 through a switch 311. After the signal is PCM-coded by a coder 340, the signal is made linear code by a decoder 350. A control circuit 320 discriminates the coincidence between the output of a switch 310 and an output of the decoder 350 and an output of a gate circuit 400 is outputted to the terminal 2. When they are not coincident, the operation is repeated again.

On the other hand, a greater part of Mn sources immediately necessary for the converter after the completion of tapping are charged into this empty converter and the Mn sources are heated and melted by making use of the heat retained in the body of the converter. Reducing agents such as Si, Al, and Ca are added to this. Immediately after the end of the vacuum treatment, the ladle contg. the molten steel is transferred into the converter and is joined with the above-described heated and Molten Mn sources.
