Title: Method for catalytic decomposition of aliphatic halide
Inventor: TAKEMOTO YOSHIMICHI
IPC: C07B37/06
Filed: 1997-05-08
Abstract: PROBLEM TO BE SOLVED: To efficiently, economically and completely detoxicate an aliphatic halogen compound such as dichlorodifluoromethane by treating the compound by using a binary catalyst consisting of ferric fluoride and/or ferric chloride as a main catalyst and cupric fluoride and/or cupric chloride as a promoter in the presence of water. SOLUTION: While using water instead of a lower alcohol, a binary catalyst consisting of ferric fluoride and/or ferric chloride as a first component (a main catalyst) and cupric fluoride and/or cupric chloride as a second component (a promoter) is used. As the reaction temperature of the catalytic decomposition system, a prescribed temperature higher than that in a conventional method is employed for efficient contact decomposition of an aliphatic halogen compound by water in the surface of the binary catalyst. By the catalytic decomposition of the aliphatic halogen compound, the compound is decomposed to CO2 , HC1, HF and byproduct formation of lower monohaloalkyl such as methyl chloride and CFC-13 is efficiently prevented or suppressed. Consequently, this method is significant as an ozone depletion preventive technique.

IPC: B29C45/76
Filed: 1991-05-09
Abstract: PURPOSE:To prevent the impulse at the starting of a screw from developing and realize the smooth and stable starting of the injection molder concerned by a method wherein the output torque of the screw is gradually raised from its initial torque to its normal torque in the pre-set starting rotational region. CONSTITUTION:Driving source 4 for rotating a screw, which can control the output torque of the screw, is provided. The starting of the injection molder concerned is started under the condition that the output torque of the driving source 4 is limited to initial torque, which is smaller than the normal torque at steady state.

Title: Multinozzle ink-jet head
Inventor: TAKADA NOBORU
IPC: B41J2/055
Filed: 1990-05-25
Abstract: PURPOSE:To prevent variation of recording dot diameters from occurring depending on driving conditions by a method wherein notches are provided to a vibrating plate in positions respectively facing each of partitioning sections in a multinozzle ink-jet head in which the vibrating plate and piezoelectric elements are provided so that they cover a plurality of pressure chambers. CONSTITUTION:Notches 121 and 122 in semicircular section are provided respectively to the upper side and the underside of a vibrating plate 11 on positions facing partitioning sections 6. The notch 121 and the notch 122 face squarely each other. As the notches 121 and 122 formed in such structure reduce the rigidity of the vibrating plate 11 on the position where the notches are formed, deformation of the vibrating plate 11 for pressurization of a certain pressure chamber exerts less influence upon a part facing an adjoining pressure chamber. therefore, when piezoelectric elements corresponding to the adjoining pressure chambers are driven simultaneously, there is little variation in the diameter of a recording dot as compared with the case where the piezoelectric elements are driven separately.
