Title: Transalkylation of naphthalenes and production of odorless aromatic solvent having high boiling point
Inventor: TOIDA YASUHIRO
IPC: C07C15/24
Filed: 1992-10-23
Abstract: PURPOSE:To produce an odorless aromatic solvent having high boiling point in high efficiency in a state to enable easy separation of the reaction product from the catalyst, causing little problem of the corrosion of the reaction apparatus and enabling the reaction in a short reaction time at a low reaction temperature to suppress the formation of by-products. CONSTITUTION:The transalkylation reaction of a fraction containing naphthalene compounds having propyl group is carried out by using a super-strong solid acid catalyst, especially preferably a catalyst produced by treating zirconia, titania, iron oxide or alumina with sulfuric acid. An odorless aromatic solvent having high boiling point can be produced from a fraction containing methylnaphthalene or dimethylnaphthalene, especially preferably a fraction consisting of a part or total of oil produced by the catalytic reforming of a kerosene fraction by propylating the fraction in the presence of a solid acid catalyst and carrying out the transalkylation of the product in the presence of a super-strong solid acid catalyst.

Title: Urinoanalysis sheet
Inventor: TSURUKAWA NAOICHI
IPC: G01N33/493
Filed: 1993-12-08
Abstract: PURPOSE:To facilitate the judgment of the degree of the color change (color tone) of a urinoanalysis color change layer by providing a urinoanalysis judging color tone, which is larger than the area of the urinoanalysis color change area, so as to cover the rear surface of the urinoanalysis color change layer on the rear surface side of the end part of a base sheet. CONSTITUTION:A urinoanalysis judging color tone 30, whose area is larger than a urinoanalysis color tone layer 20, is provided so as to cover the rear surface of the color change layer 20 on the rear surface side of the end part of a base sheet 10. The degree of the color change of the color change layer 20 at the surface side of the end part of the strip-shaped urinoanalysis sheet is compared with the judging color tone 30 at the rear surface side, and the abnormality and the presence or absence of the material under inspection in urine are judged. At this time, the color change layer 20 on the upper surface side and the judging color tone 30 at the rear surface side are overlapped and observed in continuance when the observation is performed from the upper surface side of the urinoanalysis sheet. Therefore, the judgment becomes easy without skill. Since the judgment can be performed simultaneously with dipping into the urine, the contamination of devices and the like by the scattering of the urine is prevented, and the judgment of the degree of the color change (color tone) of the color change layer 20 becomes easy. One gradation or a plurality of gradations of the judging color tone 30 are provided in correspondence with the degree of the discoloration of the discoloration layer 20.

Filed: 1994-12-13
Abstract: PURPOSE: To smoothly load and unload a tape cassette drive by providing a wound part of a torsion spring to fit from the upper side of a pin which is projectingly arranged on the inner surface of a half, and pressing the wound part under the contracting state with the wound part pressing part. CONSTITUTION: The wound part 41 of the torsion spring 4 is fitted to the pin 3 from the upper side of the pin 3 and held in the contracting state. At this time, the pin 3 is bisected through a notched part 33, therefore, each divided part comes down into the notched part 33 to enable the wound part 41 to easily fit to the pin 3. After fitted, each divided part of the pin 3 is returned to the initial position. Since the free length of the wound part 41 is formed so as to be longer than the distance between the upper end of a base part 34 and lower end of the wound part pressing part 32, the wound part 41 is horizontally held by the elastic restoring force going to return to the initial length at the time when the wound part 41 is fitted to the pin 3.

IPC: E04D13/15
Filed: 1996-11-07
Abstract: PROBLEM TO BE SOLVED: To make it possible to eliminate a trouble that a prior art synthetic resin-made surface board support allows a surface board to come off easily if there exists a large difference between the width of a surface board fit-in groove and the wall thickness of the surface board and the surface board is difficult to move if the difference is small and carry the board easily and mount the board promptly and definitely. SOLUTION: An upper plate 3B and a front board 3A are laid out interestingly at right angles. An upward surface board fit-in groove 3C is formed in the upper part of he front board 3A while a curved surface 3F is formed by projecting the upper part of a front wall 3D of the surface board fit-in groove 3C so that its side surface may expand substantially in the shape of C in a curved manner. The tip of the curved wall is arranged to be downward in the rear, thereby forming a surface board clamping section 3G which may clamp the surface board 2 between the tip and the upper plate 3B. The tip edge of the surface plate 2 loaded on the top of the upper plate 3B is adapted to fix a rafter-to-rafter board 1 clamped with the surface clamping section 3G with tip sash bar 5.  Then, the tip of the surface board 2 is arranged to slide into the surface board fit-in groove 3C as it is by pushing the surface board 2 while raising the base end of the surface board 2 so that the surface board 2 may be fitted in vertically.
