Title: Method and apparatus for winding filter cloth of filter press
Inventor: IMASAKA NOBORU
IPC: B01D25/12
Filed: 1989-03-24
Abstract: PURPOSE:To prevent the occurrence of a slack in filter cloth and separate cake smoothly from the filter cloth when a pair of filter clothes are being wound one over the other, on a single take-up roll at the time of frame opening by tensioning always the underlying filter cloth whose winding circle is smaller than the other. CONSTITUTION:Two filter cloths 18, each confronting each of the two regular filter surfaces of a filter plate 6, are run around a pair of return rolls 20 and 21 freely rotatably supported by a lower bracket 22 provided at the lower end of the filter plate 6 and wound together on a take-up roll 23 freely rotatable and always energized in the winding direction. A cleaning pipe 24 is laid across the lower end of the lower bracket 22. In such arrangement, although the filter cloth 18 running around the lower roll tends to be gradually slackened due to its winding diameter becoming smaller by the thickness of the filter cloth, by the downward movement of the return roll 20 under its own weight along an elongated hole 25, this slack is smoothly eliminated and an appropriate tension is always exerted on the filter cloth 18 on the lower roll, thereby ensuring the separation of cake.

Title: Method and system for small time key generation
Inventor: KUDO MICHIHARU
IPC: G09C1/00
Filed: 1998-03-23
Abstract: PROBLEM TO BE SOLVED: To obtain a method and system for generating a small time key from a time key. SOLUTION: Plural small time keys are generated within a time unit. A unit time deciphering key right after the time unit is generated (710). A unidirectional function is applied to the unit time deciphering key to obtain a final small time key (720). A small time key to be found is obtained by applying the unidirectional function to the small time key right before the small time key to be found. Namely, the small time key is generated from the small time key in the final order forward in time series (730). Consequently, even if a specific small time key leaks out for some reason, it is impossible to generate a small time key which is precedent in time series on the basis of the specific small time key. Further, the unit time deciphering key is safe even when small time keys are made open one after another.

Abstract: PURPOSE:To obtain the titled copolymer in good efficiency, by effecting aqueous suspension polymerization at low temperatures with the aid of a specified polymerization initiator and thus making it possible to prevent a marked increase in viscosity of the polymerization system and to improve the dispersibility of the formed polymer. CONSTITUTION:Tetrafluoroethylene and a fluorinated alkyl vinyl ether of formula I (wherein X is H or F, x is 0-4, and y is 0-7), e.g., perfluoro(methyl vinyl ether), are subjected to aqueous suspension polymerization at 0-25 deg.C in the presence of a polymerization initiator of formula II, whrein n is 1-10, in a mixed solvent (volume ratio: 1:1-10:1) consisting of water and a fluorohydrocarbon (e.g., perfluorocyclobutane) or a chlorofluorohydrocarbon (e.g., 1,1,2-trichloro- 1,2,2-trifluoroethane). Because the viscosity of the polymerization system does not increase so much, the polymer formed can be well dispersed in water, its agitation is easy, the yield of copolymer per solvent can be improved markedly to above 0.4 (in weight ratio), the amount of an expensive solvent can be saved, and the separation and recovery of the formed polymer are easy.

Title: Bending type fluorescent lamp, and fluorescent lamp device
Inventor: OGISHI KAZUHISA
IPC: H05B41/00
Filed: 1996-03-28
Abstract: PROBLEM TO BE SOLVED: To eliminate twisting for a bending part, to make deformation or damage difficult to occur, to focus a luminous part in a high density, by arranging a lamp sealing end part in a diagonal line to arrange a pair of U-shaped bending parts in a line orthogonal to the diagonal line. SOLUTION: The sealing end parts 71 and 71 of a bending type fluorescent lamp are positioned on a diagonal line O, and a pair of U-shaped bending parts 73a and 73b are positioned on a diagonal line P to arrange the end parts 71 and 71 and the bending parts 73a and 73b on both right and left sides with the diagonal line O between. This positions respective rectilinear parts 77a and 775, and 78a and 78b on the same circumference, or in the hexagonal corner parts. Thus since U-shaped curved parts 72a, 72b, and 72c, and 73a, and 73b are formed in five places, a compact shape lamp, wherein a luminous part is focused in a high density, can be obtained. While in manufacturing, applying twisting to the rectilinear part 78a and a rectilinear part 78d eliminates the twisting to the bending parts 73a and 73b.  Consequently, the retilinear parts 78a and 78d can be sufficient by one time heat softening, to facilitate bending forming of the bending parts 73a and 73b to cause no deformation or damage in the bending part, thereby preventing the thermal deterioration of a phosphor coating.
