Filed: 1983-08-30
Abstract: PURPOSE:To reduce a decrease in the quantity of light by arranging a roof prism so that two pieces of luminous flux from a lens strike two roof surfaces respectively, and providing a means which separates luminous flux projected from the roof prism into color-separated light beams in different colors and photodetection sensors on which the color-separated pieces of luminous flux are incident. CONSTITUTION:Two reflected pieces of luminous flux projected from an original O in slightly different directions are incident on the lens 7 as optical-axis light and slanting light. The two projected pieces of luminous flux from the lens are incident on two roof surfaces of the roof prism 8. The roof surfaces 8A and 8B are dichroic reflecting surfaces which have different spectral reflection factors, and only light beams in their specific wavelength bands are reflected to form images on the 1st sensor 10 and the 3rd sensor 12 respectively. Luminous flux which is split by the roof surface 8B and projected from the 3rd surface 8C forms an image on the 2nd sensor 11. Consequently, there is no decrease in the quantity of light on the optical path before the light is projected from the lens 7, the quantity of incident light on the 1st sensor 10 is 100%, and the luminous flux is split into two by the roof surface as the dichroic surface, so the quantities of incident light on the 2nd sensor 11 and the 3rd sensor 12 are each 50%.

Title: High voltage limit circuit
Inventor: TAKIZAWA KAZUYOSHI
IPC: H04N3/18
Filed: 1984-07-30
Abstract: PURPOSE:To prevent a high voltage limit circuit from being malfunctioned even when an error exists in a resistance value of a voltage divider by changing the operating point of the high voltage limit circuit as an anode current changes. CONSTITUTION:One terminal of an output voltage smoothing capacitor 5 of a winding 3 for high voltage limit circuit is not connected to ground but connected to an output of a high frequency attenuation resonance circuit 10. The amplitude of the resonance voltage generated across the resonance circuit 10 becomes larger as the anode current of the cathode ray tube becomes larger. Since the high voltage limit circuit is operated at a maximum value P of the resonance voltage, the high voltage limit circuit is operated at a voltage V2 proportional to a high voltage as the node current is larger and an output voltage of a diode 4 is lower, and when the anode current is small, the circuit is operated at a voltage V1 proportional to a high voltage. Thus, even if the resistance value of the voltage divider 6 has an error, malfunction is hardly caused.

Filed: 1987-06-26
Abstract: PURPOSE:To manufacture the titled cold-rolled steel sheet capable of facilitating the subsequent pickling treatment in a short time, by applying an aqueous solution of alkali salt to a hot-rolled steel plate containing specific amounts of Cr under specific conditions and then subjecting the above plate to cold rolling and annealing. CONSTITUTION:At the time of manufacturing a cold-rolled steel sheet containing 1-25% Cr, cold rolling is applied to a hot-rolled steel plate at 5-95% draft while applying an aqueous solution of the alkali salt of Na or K or 0.1-10% concentration, without removing the scales formed due to hot rolling. Subsequently, the cold-rolled sheet is annealed in a nonreducing atmosphere at the ordinary annealing temp. (about 500-1,200 deg.C) and then subjected to pickling for improving brightness characteristics. By this method, as compared with the case in which hot-rolled steel plate are pickled, pickling time can be remarkably shortened.

Title: Drum type classifier
Inventor: MOURI TAKUO
IPC: B03B5/56
Filed: 1980-11-10
Abstract: PURPOSE: To settle the water stagnating in a drum and to separate much finer particles from the suspension by mounting a cylindrical water receiving body having a diameter larger than the diameter of the opening part of a raw water introduction pipe mounted with an annular weir plate at the leading end to an annular end plate to a circular conical body.  
     CONSTITUTION: When raw water is supplied throutgh a hose H into a raw water introduction pipe 15, the raw water is first discharged into a water receiving body 16 mounted to an annular end plate 10, where it is once stored. When the water level of the body 16 exceeds the inside circumferential edge in the lower half part of the central part of an annular weir plate 18, the water in the body 16 overflows from the circumferential edge in the lower half part of the plate 18 and flows out into a rotary drum 1. Since this outflow does not accompany any impact at all, the water stagnating in the drum is kept still and therefore the suspended fine paricles in the raw water are settled and separated better than in conventional drum type classifiers. It is also possible to mount the body 16 to a circular conical body 11.
