Filed: 1989-03-16
Abstract: PURPOSE:To record or reproduce information with an optical system of the simple constitution which precludes optical systems, such as intermediate condenser lenses, and to decreases the noises from a recording medium by directly detecting information signals and servo signals from collimated luminous fluxes. CONSTITUTION:A 1st Faraday element which rotates the angle of polarization of linearly polarized light about 90 deg. in the optical path of the collimated luminous fluxes by the forward and backward movements of a 1st beam splitter is disposed and a 2nd Faraday element which rotates the angle of polarization of the linearly polarized light about 45 deg. by the forward and backward movements of a 2nd beam splitter 11 is disposed. The light reflected via an objective lens 3 from the recording medium 4 is partly separated by the two beam splitters 10, 11 and the separated luminous fluxes thereof are detected by respectively corresponding photodetectors 12, 13. Namely, the collimated luminous fluxes are directly detected from the respective beam splitters and the information signals and servo signals can be taken out by computation from the quantity of the received light in the plural regions of the divided photodetectors. The miniaturized optical system is obtd. in this way and the noises, etc., of the record ing medium are decreased by differentiating the outputs of the two photodetectors.

Title: Desulfurizing agent for molten iron and steel and production
Inventor: ARUBERUTO BURAUN
IPC: C21C7/064
Filed: 1980-05-13
Abstract: The invention provides an agent for desulfurizing crude iron and steel melts, the desulfurizing agent being based on calcium carbide containing calcium oxide. The desulfurizing agent is produced by admixing a calcium carbide melt having up to 45 weight % of calcium oxide therein with an excess of 3 to 15 weight %, based on the CaO-content of more than 45 up to 80 weight % desired for the final product, of calcium oxide. The resulting mixture is allowed to solidify and cool down to temperatures of 350 DEG  to 450 DEG  C. Next, the solidified melt is precrushed to material with a size of less than 150 mm. Particles with a size of less than 4 mm are screened off and the remaining material is comminuted, with the exclusion of moisture, to material with a size of less than 10 mm.

Title: Thin-film transistor
Inventor: YAMAZAKI TSUNEO
IPC: H01L29/78
Filed: 1984-03-30
Abstract: PURPOSE:To lower contact resistance, to improve the rectifying properties of a contact and to reduce OFF currents by forming source and drain electrodes and a collector in a semiconductor thin-film to an inclined plane shaped to the end section of the semiconductor thin-film. CONSTITUTION:A source 7 and a drain 8 are formed on an inclined plane shaped to the end section of an amorphous silicon film 4. The source 7 and the drain 8 are superposed to a plane shape through a gate insulating film 3. Since the source and the drain are superposed to a channel region, the resistance of an R section can be ignored. Since there is no section in which the amorphous silicon film 4 and source and drain electrodes 5, 6 are directly in contact, the titled transistor has excellent rectifying properties in the joining of the source and the drain, Hall currents flow, and leakage currents are not increased.
