Title: New acrylic monomer and its production
Inventor: NAKANO SHINJI
IPC: C08F290/00
Filed: 1994-05-02
Abstract: PURPOSE:To provide a new acrylic monomer having a chain carbonate structure in an ester residue and useful as a raw material for the production of a polymer having chain carbonate pendant groups by copolymerization. CONSTITUTION:This acrylic monomer is a compound expressed by formula I (R<1> is H or methyl,; R<2> and R<3> each is a 2-8C alkylene chain; R<4> is a <=20C primary alcohol residue; (m) is O-6; (n) is l-100). The compound of formula I can be produced by the transesterification reaction of a monoalcohol of formula II with a reactive derivative of acrylic acid or methacrylic acid (e.g. a lower alkyl ester) in the presence of a catalyst (e.g. a protonic acid). The reaction is preferably carried out at a temperature between the boiling point of the by-produced methanol, etc., and 150 deg.C while removing the by-produced methanol, etc., from the system to shorten the reaction time and prevent the polymerization. Polymers copolymerized with the monomer have improved physical properties such as oilresistance, heat-resistance and low-temperature impact resistance.

IPC: C07F9/50
Filed: 1988-05-14
Abstract: PURPOSE:To To nearly prevent a thin film from taking in carbon during P- contg. crystal film formation and to produce a high quality thin film by using a specified organophosphorus compd. CONSTITUTION:When a thin film of P-contg. crystals is formed, an organo- phosphorus compd. represented by the formula (where R is halogen and n=0-5) is used as starting material for P. The organophosphorus compd. and an organometallic compd. are filled into vessels for feed and introduced into a decomposition furnace with carrier gases. The amts. of the compds. fed are regulated by controlling the temps. and the flow rates of the carrier gases. In the furnace, the compds. are thermally decomposed and vapor-deposited on a heated substrate. In the organophosphorus compd., the bond of P to C the methylene of the benzyl group is easily dissociated by heat, so as thin film hardly takes in carbon during formation and a high quality thin film of P-contg. crystals is obtd.

Title: Memorizing method for character, figure and the like and photocomposing device
Inventor: FUKUDA SHINICHIROU
IPC: G09G5/24
Filed: 1980-08-22
Abstract: PURPOSE: To prevent deterioration of quality even in the case of a high magnification and enable a single piece of data to suffice irrespective of the magnitude of magnification by storing a character, a figure or the like as profiles approximate to curves.  
     CONSTITUTION: The character is resolved into 100×100 dots, followed by correction of data, determination of profile elements and determination of data for each of the profile elements. After completing these operations, when the character is scanned from left to right and in the downwad order, the upper part "," of the character ""ei"(Japanese:kanji,314A)" is scanned first. The profile elements 20W23 of the part "," are stored in the scanning order, i.e. in the order of 20, 21, 23. When a scanning line crosses a profile element on one side of a picture element part of the character, it will necessarily cross a profile element on the opposite side correspondig to the profile element on the one side. Therefore, the profile elements are always stored as pairs. However, in the case of the profile element 21 for which the first pair-forming profile element 20 is short, the storing of the final point of the profile element 20 is immediately followed by the storing of the next profile element 22.

Abstract: PURPOSE:To produce automatically a decision tree dictionary having a small number of pieces of feature quantity extracted out of a category before the result of recognition is outputted from the data on distribution of plural categories on a feature quantity axis, by shortening the maximum recognition time (for one of categories) and the integrated recognition time (needed for recognition of all categories) independently of each other. CONSTITUTION:High-order classes {A, B, C, D, E, F, G, H} consisting of plural categories are sorted on a feature quantity axis and decomposed into low-order classes {A, B, C}, {D, E, F} and {G, H} respectively. Under such conditions, the subsequent decision trees are assumed from the number of categories of the low-order classes. The maximum recognition time of the virtual decision tree starting at a feature quantity X, i.e., the number of feature quantities (maximum assumed depth) that are extracted between the quantity X and the deepest area at the tip of the decision tree or the integrated recognition time, i.e., the number of the quantity X (sum of assumed nodes) which are extracted between the quantity X and all tips of the decision tree are used as the standard of evaluation when the feature quantity is selected. When those classes are sorted at all times with the maximum assumed depth set at the minimum quantity X, the maximum recognition time can form a small decision tree. While the integrated recognition time can form a small decision tree if said sorting is always performed with the assumed sum of nodes set at the minimum quantity X respectively.

IPC: B23D61/04
Filed: 1982-07-07
Abstract: PURPOSE:To improve the cutting capacity of a saw by a method wherein chips are properly curled and consequently smoothly discharged and yet respective segments are made in the same form. CONSTITUTION:In order to cut steel material or the like, a circular saw is rotated at a predetermined rotational frequency (cutting speed) and a predetermined feed (depth of cut) is given to the circular saw 1 or workpiece material in order to continuously perform quantitative cutting by means of one by one tooth of the segment 3. Because the second rake faces 8, which are inclined backward with a lead angle and are plane symmetrical in form, are formed on the rake face 4 of the segment 3, chips are produced in a bent form and accordingly discharged smoothly. Consequently, the cutting load is applied uniformly over the whole cutting teeth, resulting in increasing the durability of the saw.
