  • Publication number: 20240103495
    Abstract: Feedback is provided, based on an actual drive amount of an actuator, to a command to a subsequent actuator. A control system includes a memory configured to store a program configured to generate a command related to a working position, a controller configured to execute the program, a first output unit configured to output a drive signal to a first drive portion, a second output unit configured to output another drive signal to a second drive portion, and a measurement unit configured to measure a drive amount of the first drive portion. The controller is configured to extract a low-frequency component included in the command, transmit the low-frequency component to the first output unit, correct a high-frequency component included in the command based on a signal indicating the drive amount of the first drive portion, and transmit the high-frequency component to the second drive portion.

  • Patent number: 6952550
    Abstract: A toner supply roll free from occurrence of an imaging failure. The toner supply roll comprises a shaft (1) and a urethane foam layer (2) provided on an outer peripheral surface of the shaft (1), wherein when the urethane foam layer is compressed to a depth of 1 mm from an outermost surface thereof during compression thereof to a depth of 2 mm, a stress F0 occurs in the urethane foam layer and when the urethane foam layer is decompressed to a depth of 1 mm after the compression thereof to a depth of 2 mm, a stress F1 occurs in the urethane foam layer, the urethane foam layer satisfies a relation represented by the following expression (1) at a temperature of 23±3° C. at a humidity of 50±10%: F1/F0?0.7??(1) the stresses F1 and F0 being expressed by a unit of Pa.

  • Patent number: 6504073
    Abstract: A method for converting benzene and aromatic hydrocarbon compounds having 9 or more carbon atoms contained in a material oil having a boiling point of 30˜210° C. into toluene and aromatic hydrocarbon compounds having 8 carbon atoms in the presence of hydrogen and the said catalyst. The catalyst can be obtained by carrying at least one metal or metal compound selected from Group VIII and Group VIA of the Periodic Table on a carrier containing zeolites in which maximum diameter among diameters of its micropores is 0.6-1.0 nm and a ratio of SiO2/Al2O3 is 50 or more.

  • Publication number: 20010014645
    Abstract: There is provided a catalyst exhibiting a high activity and less catalytic deterioration, as well as a high selectivity, suitable for use in allowing aromatic hydrocarbons of 9 or more carbon atoms to react, and thereby converting them into toluene and aromatic hydrocarbons of 8 carbon atoms more useful as gasoline bases, and a conversion method using the catalyst. The catalyst is used for converting aromatic hydrocarbons of 9 or more carbon atoms in a material oil containing a component with a boiling point exceeding 210° C. into toluene and aromatic hydrocarbons of 8 carbon atoms in the presence of hydrogen, and contains a carrier containing one or more than one zeolites in which the maximum pore diameter of micropores is in a range of 0.6 to 1.0 nm; and one or more than one metals selected from the Group VIA metals of the Periodic Table or compounds thereof.
