Patent JP-S6470446-A (JP)
Title: Production of cyclohexylamine
Inventor: NARAMOTO ISAO
IPC: B01J23/74
Filed: 1988-02-17
Abstract: PURPOSE:To obtain the titled compound in high yield, under a relatively low pressure condition, suppressing the production of by-products, by hydrogenating anilines with hydrogen gas in liquid phase in the presence of ammonias and an Ni catalyst and distilling out the gas containing produced objective compound from the system. CONSTITUTION:Anilines are hydrogenated with hydrogen gas in liquid phase in the presence of an Ni catalyst. The reaction is carried out in the absence of solvent under a reaction pressure of 2-10kg/cm<2>, preferably 6.5-7.5kg/cm<2> (gauge pressure), in the presence of ammonias at a molar ratio (hydrogen: ammonias) of about 5:0.5-3 at 210-240 deg.C and the gas containing produced objective compound is distilled out in vapor phase from the reaction system. The unreacted anilines and by-products in the distillate are separated from the objective compound and continuously introduced into the reaction system together with raw material anilines. The side reaction is suppressed by the presence of ammonias. Since the produce is distilled out of the system in vapor phase, the distillation loss of the catalyst can be prevented and the catalytic activity can be maintained.

Filed: 1978-03-29
Abstract: PURPOSE: To attain smoothed simultaneous operations of a hydraulic motor and other actuators in a hydraulic circuit by constituting the hydraulic circuit such that hydraulic cylinders adapted to raise and reduce the hydraulic pressure are provided between a direction change-over valve of a hydraulic motor circuit and other actuators.  
     CONSTITUTION: If a switch 22 is closed, pressure on the head side of an actuator 9 is raised. Then, if another switch 21 is closed, change-over valves 15, 16 are changed over to their left position. At this time, a hydraulic motor 8 and the actuator 9 effects a composite operation. When a change-over valve 13b is restored to its neutral position to brake the hydraulic motor 8, if the pressure of the actuator 9 is lower than the brake pressure of the hydraulic motor 8, pressure oil discharged from the hydraulic motor 8 flows into a rod chamber of a hydraulic cylinder 7 to actuate the rod to thereby supply pressure oil in the hydraulic cylinder into the actuator by way of a check valve 19. Thus, the amount of actuation of the actuator 8 is increased and besides there is not loss of energy.

Title: Bobbin holder
Inventor: HASEGAWA KATSUMI
IPC: B65H54/547
Filed: 1986-02-20
Abstract: PURPOSE:To lengthen a holder's hollow part as well as to make such a long-size bobbin holder that uses a small diametral bobbin and is rotatable at high speed fromable, by making wall thickness of the hollow part of a bobbin holder part so as to become thickened at the connecting part side of a holder shaft but thinned at the end side, respectively. CONSTITUTION:A part, where a bobbin holder shaft 5 and a bobbin holder part 2 are unitized in one, is formed into such a structure that wall thickness of a rear cylindrical member 4 becomes thinned in proportion as it extends toward an edge of the holder part 2, and since it becomes thinned nearly about 1/2 of hollow part length, a thin part in the wall thickness of the member 4 is somewhat lower in rigidity but its dead load is reduced. However, at the fixed part side supporting the rear cylindrical member, the wall thickness is thickened, so its rigidity comes high. That is to say, in the member 4 supported by the fixed part, the rear end on which a part of the dead load exerts a larger effect than the rigidity, and the fixed part side to which the rigidity largely contributes both are formed into such a structure as making a critical speed of the member 4 higher than a working revolution range in proportion as a distance from the fixed part separates away. Therefore, stable high-speed rotation is made attainable, and a smaller diameter of the bobbin is well promoted so that long-size promotion in the bobbin holder is realizable.
