Title: Optical disc recording and reproducing system
Inventor: NAGASHIMA MICHIYOSHI
IPC: G11B7/005
Filed: 1982-03-10
Abstract: PURPOSE:To improve the frequency characteristics of recording and reproduction and to attain high density, by providing a groove having V-shaped (or inverted trapezoid) cross section in the radial direction on an optical disc and making an ellipsoidal optical beam incident. CONSTITUTION:The groove having V-shaped radial cross section is formed in a layer of resin cured by ultraviolet rays on a transparent disc substrate 1,  and a photo sentitive recording material layer 3 is provided on the resin layer.  The ellipsoidal optical beam having the major axis in the direction in parallel  with the groove is made incident from the substrate 1 for recording and reproduction. In making the double pitch 2P of a width P of the groove equal to a conventional track pitch, the mixing of signals from planes A and E is less at  the reproduction of a plane C and the mixing of signals from planes B and D is minimized by determining the shape of cross section of the V groove. Since the ellipsoidal optical spot is used, the frequency characteristics are improved by decreasing the aperture diameter toward the track direction and high density is attained.

Title: Flue gas desulfurizing method
Inventor: MINEMOTO MASAKI
IPC: B01D53/34
Filed: 1993-02-26
Abstract: PURPOSE:To lower the cost of a desulfrizing agent when using slightly calcined magnesia as the desulfrizing agent by feeding it as it is into a liquid absorbent tank in the bottom part of a desulfurizing column. CONSTITUTION:Slightly calcined magnesia in a MgO storage tank 1 and water in a water feed line 2 are fed into a MgO dissolving tank 3 through piping 10, 11 respectively to agitate them by an agitator 4. Then liquid in the MgO dissolving tank 3 is introduced into a liquid absorbent tank 5 in the bottom part of a desulftrizing column through piping 12. Since when a desulfurizing agent is fed, it is thus introduced directly as MgO without hydration treatment, a sedimentation tank, a wet grinder, a MgO dehydration tank, etc., are saved to lower the running cost.

Title: Bar graph recognizing device
Inventor: TAI SHINKOU
IPC: G06K9/00
Filed: 1996-02-26
Abstract: PROBLEM TO BE SOLVED: To provide a recognizing device capable of recognizing the structure of various bar graphs and converting graph information into numerical data capable of reconstraction or inter-data relation. SOLUTION: Character image data out of image data are segmented by a character separating part 3 and recognized by a character recognizing part 4. On the other hand, graphic image data are separated by a graphic separating part 5 and vertical and horizontal segments are extracted by a segment extracting part 6. A segment intersection detecting part 7 finds out the intersection of segments and a graph element detecting part 8 detects the reference axis and direction of a bar graph and the axis of actual data from the distribution of intersections. A scale line extracting part 9 extracts a scale line based on the actual data axis. A bar item extracting part 10 extracts a bar rectangle based on the direction of the bar graph.  A data conversion part 11 reads out a numeric value corresponding to the scale line extracted by the extracting part 9 by the use of a character code obtained by the recognizing part 4 and converts the bar item extracted by the extracting part 10 into its corresponding numerical data.

Title: Dividing feed device for grain
Inventor: YAMAGUCHI TETSUJI
IPC: B29C47/10
Filed: 1989-02-21
Abstract: PURPOSE:To simply and inexpensively divide grain into two flows of grain at an arbitrarily predetermined ratio by providing a grain receiver that receives the grain which freely drop down without impinging against turning blades and also a grain receiver that receives the grain which is spattered by the turning blades. CONSTITUTION:When a motor 3 is operated to turn a bladed wheel 5 and granular materials such as, for example, plastic pellets are charged into a supply part 2 in a specified quantity and at a predetermined flow rate, the materials among these dropping down from a bottom end opening 2' of the supply part 2, which pass between blades 6 and freely drop down without impinging against the turning blades 6, enter a grain receiver 7. On the other hand, the materials that impinge against the turning blades 6 to be spattered drop outside the range of the grain receiver 7 and are collected into another grain receiver 8. Accordingly, the grain materials are dividedly fed at a predetermined ratio and collected into the two receivers 7, 8. The divided feed ratio can be controlled by varying the number of rotations of the blades, and further, the grain materials can be dividedly fed at the same divided feed ratio even when the supply flow rate of the grain materials varies. By this method, the grain materials can be inexpensively divided into two flows at an arbitrarily predetermined ratio by simple structure.

Filed: 1985-02-26
Abstract: PURPOSE:To prevent accumulating capacity of positive charges from decreasing, by forming a high dielectric constant insulating film through at least a conductive film at a region for a capacitor to be formed, and by employing the conductive film as one electrode of the capacitor. CONSTITUTION:After a field oxide film 2 is formed on a semiconductor substrate 1, a WSi2 film 6 is selectively formed at a capacitor forming region of the semiconductor substrate 1 where the silicon is exposed, with a CVD method. Next, a silicon oxide film 3 is formed on the entire surface, and then a polycrystalline silicon film 4 is formed thereon. Leaving a gate region, the polycrystalline silicon film 4 and silicon oxide film 3 are removed, and impurities are diffused into the exposed semiconductor substrate 1 to form source and drain regions 5. In this way, since the WSi2 film 6 serving as a high dielectric constant insulating film is formed just below the silicon oxide film 3 serving as a capacitor insulating film, charge accumulating capacity can be increased and thus a high performance semiconductor device which can be highly integrated can be provided.
