Title: Temperature control method for ultraviolet lamp
Inventor: SHIMAKURA TAKESHI
IPC: C08J7/00
Filed: 1999-09-14
Abstract: PROBLEM TO BE SOLVED: To easily equalize temperature of a tube wall of a tubular ultraviolet lamp along length. SOLUTION: In this temperature control method, outside air is sent from a blower through a blow damper 13a opened to a specified opening into a gap between two of an upper and a lower baffle plates 12 in a lamp house 10 to go through the gap between the baffle plates 12, flow into reducers 16 provided at a front edge side and a rear edge side of the baffle plates 12, increase its blow speed by action of the reducers 16 and become thin air currents, and be discharged from openings in the reducers 16, so it is uniformly blown to tubular walls of socket parts at both ends of respective ultraviolet lamps 11 only. Temperature of the tubular walls of the lamps 11 is thus easily equalized along their length.  Temperature around the socket parts at both ends of the lamp in the lamp house 10 is detected by a temperature measuring resistance 15a, and opening of the blow damper 13a and a discharge damper 14a is automatically adjusted by a command from a temperature regulator 15, thereby blow quantity and discharge quantity of outside air into/out of the lamp house 10 can be automatically regulated.

Title: Qualitative modification of wood by silk fibroin
Inventor: SHIMADA KATSUHIRO
IPC: B27K3/34
Filed: 1994-10-01
Abstract: PURPOSE: To improve dyeing affinity and ameliorate dimensional stability and coating performance by impregnating a wood with an aqueous silk fibroin solution or applying it to the wood, then allowing the solution to be cured, and compounding both fibroin and the wood to extend the range of dye selection. CONSTITUTION: Fibroin is obtained by treating silk in alkali and removing sericin. However, recycled fibroin (silk fibroin) is obtained by dissolving an industrial waste such as rejected cocoon as a raw material in a water solvent and dialyzing the solution. A wood to be dyed is impregnated with silk fibroin by impregnating the wood with an aqueous fibroin solution at normal temperature, and then silk fibroin and the wood are compounded by curing through a drying process. The wood thus treated using the fibroin indicates improved dyeing affinity and dimensional stability, if the wood is dyed using an acid dye or an edible color and dried. This is because the silk fibroin with an affinity for dye penetrates the cellular wall of the wood or becomes fixed and cured on the surface of the wood depending on the degree of molecular weight of the fibroin, due to the compounding process.

Filed: 1999-09-16
Abstract: PROBLEM TO BE SOLVED: To reduce lubricating oil to the necessary minimum oil feeding quantity while maintaining oil feeding pressure to make lubricating oil reach a bearing and a gear of a shaft to rotate at high speed. SOLUTION: Self-excited vibration is generated by properly setting pressure of a supply system 10 reaching an oil jet from an oil pump 1 to a time constant and characteristic frequency of a pressure governing valve 12, and oil is fed while maintaining the maximum oil feeding pressure by timely changing oil feeding pressure in the case of feeding lubricating oil to be supplied from the capacity type oil pump 1 by the oil jet. Consequently, total oil feeding quantity is reduced by timely changing oil feeding pressure by using pulsation of oil feeding pressure.

Title: Character recognition device and item classifying method
Inventor: KUWATA MINAKO
IPC: G06K9/20
Filed: 1998-09-16
Abstract: PROBLEM TO BE SOLVED: To obtain high item classification precision for a document image wherein a specific format is repeated. SOLUTION: A temporary item imparting processing part 17 imparts a temporary item to a character string recognized by a character recognition part 14 referring to dictionaries 18 and 19. A block extraction part 23 divides the contents of a character recognition buffer 15 and a temporary item buffer 20 into blocks according to ruled lines. A recognition postprocessing part 24 performs recognition postprocessing according to the rule that item information present in one block is common to the respective blocks. An item classification part 26 performs regular item imparting by verifying the contents of the temporary item.  In this case, the regular item name and item label name which contradict the common format are corrected according to the rule that the information in one block is common to the respective blocks, and hence an item label name which is misrecognized or unregistered and the item of an unregistered character string can be corrected correctly.

Abstract: PURPOSE: To press all muntins into secure contact by molding each shoulder portion of one side of steel serving as the front into a diagonal or arc shape, and performing embossing through the contact between the front and back and one of two side surfaces at a predetermined angle during pressing, and correcting a curve formed. CONSTITUTION: Each shoulder portion of one side 1a of steel 1 is formed into a diagonal or arc shape by upper and lower calipers 2a, 2b. Therefore, embossing calipers are not stressed. Next, flange portions 6a, 6b are provided in the steel by means of calipers 3a, 3b. Next, the surface 1a is made uneven by means of calipers 4a, 4b. Therefore, when pressed the surfaces 1a, 1d and one side surface 1b of the other two side surfaces 1b, 1c are brought into contact at approximately 90 deg. for embossing. Then the surface 1d is formed into a plane perpendicular to approximately the cross direction and prevents collapse during pressure contact. Thereafter, a curve formed by the calipers 5a, 5b is corrected. Therefore, twist bars are correctly spaced and all muntins 7 can be securely welded to time twist bars.
