IPC: C08J9/00
Filed: 1997-04-04
Abstract: PROBLEM TO BE SOLVED: To obtain a cellular polymer capable of having extremely small and uniformly dispersed fine pores and suitable for using as an electronic part by performing a reaction comprising three steps by using a precursor of a polysiloxane and heat decomposable particles. SOLUTION: This cellular polysiloxane polymer is obtained by (A) dispersing heat decomposable particles in a polysiloxane precursor, then (B) forming a hard polysiloxane by polymerizing (and preferably crosslinking) the polysiloxane precursor without decomposing the particles, and (C) heating the polysiloxane to decompose to particles without expanding the polysiloxane. Further, the above particles preferably contain a polymethyl methacrylate. The pore diameter of the obtain cellular material is preferably and approximately 1-10μm. Thus, the fine pores are uniformly dispersed in the bulk of the polymer, and the pore diameter can be adjusted by changing the size of the heat decomposable particles.

Abstract: PURPOSE:To simplify the working of a production process of window frames, or the like with the use of a work shifting device, by incorporating, on a carrier vehicle, a transfer member which is movable in the travelling direction of the vehicle and a transfer member which is movable in the direction orthogonal to the travelling direction and elevatable. CONSTITUTION:A workpiece W on a feed bed is introduced into a transfer member 4, overriding a second transfer member 5 having its transfer surface 5a which is slightly lower than the transfer surface 4a of the first transfer member 4. Further, a carrier vehicle 3 is moved to a position in front of a pooling bed 10. Then the transfer member 5 is raised upto the position where the transfer member 5 becomes frush with the transfer surface 52a of a receiving member 52, exceeding the transfer surface 4a, and the workpiece W is shifted onto the second transfer member 5 at a right angle to the latter. Then the workpiece W is pushed out to be shifted onto the receiving member 52. Further, an elevator bed 37 is extended to shift the workpiece onto a receiving member 51 in an upper stage. Further, the position of the carrier vehicle 3 is changed, and the vechicle is moved outward in the reverse direction under reverse action such that a plurality of workpieces W are pooled on the receiving members 51, 52, respectively. With this arrangement, the shifting of the workpieces may be simplified.

IPC: H01J29/50
Filed: 1981-06-08
Abstract: PURPOSE:To obtain an inexpensive electroagnetic focusing type cathode-ray tube offering a beam spot being truly round and excellent satic convergence, the cathode-ray tube being readily assembled with high accuracy, by a method wherein a sectional external shape at a right angle to the tube axis of a yoke is made non-circuilar in order to allow the yoke to be supported by an electrode-upporting rod commonly used for other electrodes, and the shape of a permanent magnet, the length of a gap between the yokes, the lenght of the yoke in the direction of its tube axis are set at values within the range of satisfying particular correlation. CONSTITUTION:What is greatly different from the convertional example is that the external shapes of yokes 51a, 51b and a gap electrode are flat, the yoke and the gap electrode 14a being supported by an electrode-supporting rod 9a commonly used for other electrodes by utilizing a gap between the flat portion and the inside wall surface of a nexk tube. As a permanent magnet, taking it into consideration that the magnet is used for a television for household use, the one made of ferrite will be most suitable in view of its performance vs. cost ratio. Moreover, by defining the shape of the permanent magnet having outside and inside diameters Fo, phii and t in thickness as 1.7<=phio/phii<=23, 0.35<=t/phii<=0.65, it becomes possible to obtain such a cathode-ray tube free from a shear in color, distortion in the shape of a beam spot, and the one which is readily assembled with high accuracy.

Title: Alloyed galvanized steel sheet coated with organic resin
Inventor: NOMURA SHINGO
IPC: B32B15/082
Filed: 1990-03-30
Abstract: PURPOSE:To impart high powdering resistance and high flaking resistance and obtain an alloyed hot-dip zinc-coated steel sheet coated with an organic resin, which has highly sliding characteristics, by forming an organic resin layer containing a specific weight percent of fluorocarbon resin particles on the surface of the iron sheet in a specific amount of coating. CONSTITUTION:In an alloyed hot-dip zinc-coated steel sheet coated with an organic resin, an organic resin layer forming an organic resin coating contains 2-40wt.% of fluorocarbon resin particles. If the content of the fluorocarbon resin particles is less than 2wt.%, the friction coefficient of the coating becomes greater and, if the content thereof exceeds 40wt.%, the organic resin layer tends to be peeled off the alloyed hot-dip zinc-coated steel sheet. An amount of the organic resin coating applied to the iron sheet is within a range of 0.1-5g/m<2> and, if an amount of application is smaller than 0.1g/m<2>, the effects of lubricating properties and resistance to corrosion are not sufficient. On the other hand, if it exceeds 5g/m<2>, the organic resin coating tends to be peeled off during a pressing operation and is attached to a metallic mold, whereby there is the possibility of causing defect in the pressing. Accordingly, by adjusting one or both of the content of particles and the amount of the coating to be applied to the steel sheet, the friction coefficient of the iron sheet can be optimized.

Abstract: PURPOSE:To correct a ratio of longitudinal and transverse sizes of characters to a certain value by providing a character size correcting means which corrects a ratio of longitudinal and transverse sizes of characters, which are recognized by character size information obtained by a character size processing means, to the certain value. CONSTITUTION:A position input device 1 has a coordinate position detecting function to input coordinate position data described on the surface of the device 1 with a pen or the like. This input position data is read in by a controller 3, and position data is used to recognize described characters by the controller 3 and the size of characters is determined. Characters are different in size; but if correction of the character size is designated, a ratio of longitudinal and transverse sizes of a first character is corrected to a certain value to unify the character size. Recognized characters are displayed on a display device 2 in the corrected character size. Thus, characters different in size are corrected to the uniform character size and are displayed.
