Title: Production of olefin-free tertiary amyl alkyl ether-rich fraction and normal pentane-rich paraffin fraction
Inventor: PATORITSUKU SARAZAN
IPC: C07C41/05
Filed: 1992-08-21
Abstract: PURPOSE: To simultaneously obtain a tert. amyl alkyl ether-rich fraction and an n-pentane-rich fraction from a 5C fraction contg. isopentenes, cyclopentene and dichloropentadiene.  
     CONSTITUTION: An olefin-rich 5C hydrocarbon fraction contg. isopentenes is hydrogenated as feedstock with hydrogen and a sulfur compd. at 20-150°C and 5-100 bar in the presence of a catalyst contg. a group VIII noble metal, e.g. alumina carrying Pd. The hydrogenation effluent is fractionated to obtain a 5C-rich fraction and a 6C fraction. The 5C-rich fraction is sent to an isoolefin etherification zone using an alcohol such as methanol, and after distillation, the objective fractions are obtd. By the combination of the hydrogenation, etherification and separation steps, the value of the 5C fraction from steam cracking is enhanced.

Filed: 1996-08-23
Abstract: PROBLEM TO BE SOLVED: To provide a highly durable developing roller at a low cost by inserting a ring shape member between the end part of a magnet roller and a supporting member. SOLUTION: The developing roller has a structure arranging a sleeve 20 of aluminum on the periphery of the magnet roller 10 with a slight gap, and fixing the respective supporting member 21 and 22 on the end part. Then, the development is performed by composing a shaft 21a of the supporting member 21 in freely rotationally, transporting toner held on the sleeve, and making it stuck on an electrostatic latent image on a photosensitive drum.  In the meantime, by inserting respective ring shape member 13 between either end part 11 of a magnet main body part 11, and several supporting members 21 and 22, either end part of the magnet roller 10, and either shaft 12a and 12b is prevented from coming into direct contact with respective surface side of the supporting member on the sleeve inside surface side, therefore the 'play' caused by the wear on the side surface of the magnet roller 10 and the shaft 12 can be prevented.

Title: Optical fiber testing device
Inventor: RAN MUNEKI
IPC: G06Q40/00
Filed: 1985-10-07
Abstract: PURPOSE:To utilize two polarized components in back scattered light and to obtain a testing device small in loss of signal light and long in trouble point search distance by photodetecting the outputs of the 1st and the 2nd polarization splits. CONSTITUTION:The light pulse output of a semiconductor laser 1 is guided to a polarization splitter 31 through a lens 21. At this time, a control circuit 13 does not drive a polarization plane converting element 4, so the output light is incident on a fiber 6 to be measured through the element 4, splitter 31, and a lens 22. Back scattered light generated in the fiber 6 is not polarized and passed through the lens 22, so that its vertical polarized component is incident on a photodetecting element 5 through the splitter 32 and lens 23. Its horizontal polarized component, on the other hand, travels straight in the polarization splitter 32 to enter the element 4. At this time, the element 4 is driven, so the horizontal polarized component turns to a vertical polarized component and enters a photodetecting element 52 through the splitter 31 and lens 24. The outputs of the elements 51 and 52 are amplified 91 and 92, then added 10 together and processed 11. Thus, the polarized component which is not used before is photodetected at the same time.
