Title: 14-fluorodaunorubicin derivative
Inventor: TERAJIMA ATSURO
IPC: A61K31/7034
Filed: 1987-01-30
Abstract: NEW MATERIAL:A compound expressed by formula I (R<1> is H or trifluoroacetyl). USE:A carcinostatic agent. PREPARATION:For example, a daunorubicin derivative expressed by formula II is initially brominated and then reacted with a fluoride to provide a compound expressed by formula III, which is then acetalized to afford a compound expressed by formula IV (R<2> and R<3>, together with the carbon atom to which both are linked, represent acetal; R<4> is acyl). Bromination of the 4-position, conversion of the brominated substance into a hydroxide and removal of the acetal group are successively carried out to produce a compound expressed by formula V, which is then reacted with a daunosamine derivative expressed by formula VI to provide an alpha-glycoside expressed by formula VII, which is subsequently deprotected (R<1> is trifluoroacetyl).

Title: Recovering device for volatile hydrocarbon vapor
Inventor: TAWARA HIROSHI
IPC: B01D53/44
Filed: 1984-02-06
Abstract: PURPOSE:To dispense with a level controlling device in a recovering device for volatile hydrocarbon vapor by installing a vacuum evaporator to the bottom of an absorption tower so as to maintain the liquid level of the bottom of the absorption tower. CONSTITUTION:Gas 2 contg. hydrocarbon vapor is introduced from the bottom of an absorption tower 3 and is allowed to contact with absorption liquid 4 countercurrently to cause absorption of the hydrocarbon vapor. The liquid after absorbing the hydrocarbon vapor is dropped into a vacuum evaporator 6 through a float valve chamber 20. While the float valve chamber is filled with liquid, the absorption liquid is sent to the vacuum evaporator. If the float valve chamber becomes empty, it is closed automatically. Therefore, the vacuum evaporator is held at a fixed degree of vacuum. The hydrocarbon contained in the absorption liquid introduced into the vacuum evaporator is withdrawn by a pump 7 and recovered by cooling and liquefying with a cooling device 21, and remaining absorption liquid is used again circulatorily.

Title: Magnetic driving type electrode for vacuum interrupter
Inventor: NODA TAIJI
IPC: H01H33/66
Filed: 1989-01-31
Abstract: PURPOSE:To improve interrupting performance by making the outer diameter of a contact surface not larger than the diameter of a lead rod, and causing the current components between the contact surface and the lead rod during current feeding to be such that the component in the direction orthogonal to the contact surface is larger than the component in the direction parallel to the contact surface, and forming an arc part from a material containing a magnetic material. CONSTITUTION:During current feeding and immediately after contact opening (during the presence of an arc on a contact surface 31a), most part of current path is orthogonal to the contact surface 31a, so that the arc is spread radially by self-diffusive force of metal vapor generated upon interruption, and is moved from a contact part 31 to the arc part 30. Because the arc is moved from the contact part 31 to the arc part 30 while being in dispersed state, the energy of individual arc columns are small, and further, because the arc part 30 contains a magnetic material, the magnetic flux density at the pedal surface of each arc pedal 30a is increased. Accordingly, the rotational drive force acting in particular on the foot part of each arc column is suppressed, so that the moving force F1 in the direction outward from the pedal is weakened. As a result, the arc is moved in the F2 direction and current interrupting performance is improved.

Title: Method and apparatus for treating petroleum
Inventor: KONDO SADAO
IPC: C10G45/02
Filed: 1994-02-16
Abstract: PURPOSE:To treat petroleum at a low cost with a simple apparatus by distilling a crude oil under the normal pressure to separate it into a residual oil and a distillate oil and hydrogenating the distillate oil collectively with one hydrogenation apparatus. CONSTITUTION:A crude oil pretreated, e.g. dewatered and desalted, is fed to a rough-distillation apparatus 11, distilled under the normal pressure, and thus separated into a light oil, a distillate oil comprising fractions more volatile than the light oil, and a residue (a normal-pressure residual oil). The distillate oil is collectively fed to a hydrogenation apparatus 12 and where brought into contact with hydrogen in the presence of a catalyst to be subjected to hydrogenation such as desulfurization. The resulting refined oil is fractionated into a refined light oil, a refined kerosene, a refined heavy naphtha, a refined light naphtha, a refined LP gas, and an off-gas (a light gas). Thus, the construction of a petroleum refinery system is greatly simplified and the construction cost and equipment space are greatly reduced in comparison with the conventional method wherein a crude oil is distilled and separated into various fractions and then each fraction is hydrogenated separately.

Abstract: PURPOSE:To prevent dust or the like from being taken-in and to uniformly apply ultraviolet setting resin by enlarging the size of a screen for applying the ultraviolet ray setting resin to a disk substrate rather than the moving range of a squeegee. CONSTITUTION:At the screen printing part of an optical disk substrate manufac turing device, a mask device is provided to apply ultraviolet ray setting resin 9 to a disk substrate 6 held to a printing stand 8 with vacuum chucking. For the mask device, a screen 18 equipped with plural through holes, which are bored corresponding to a printing pattern, is put up through an elastic matter 19 to a frame body 20. The elastic matter 19 and the screen 18 are adhered at an adhesion part 21.
