  • Patent number: 8442530
    Abstract: The present invention relates to a device that includes a radio network control device operable to control a plurality of radio base stations. Also included is a grouping processing unit operable to group into a same group many mobile devices that perform handover to a specific radio base station in a predetermined period.

  • Patent number: 7908940
    Abstract: A bar end electric shifter is provided with a handlebar mounting portion, an electrical switch housing portion, a first electrical shift operating member and a second electrical shift operating member. The handlebar mounting portion is configured to be fixedly mounted to a free end of a bicycle handlebar. The electrical switch housing portion extends longitudinally from the handlebar mounting portion. The electrical switch housing portion has first and second lateral sides with a center axis of the free end of the handlebar extends longitudinally through the electrical switch housing portion when the handlebar mounting portion is mounted to the free end of the bicycle handlebar. The first electrical shift operating member is located on one of the lateral sides of the electrical switch housing portion. The second electrical shift operating member is located on one of the lateral sides of the electrical switch housing portion.

  • Patent number: 7861953
    Abstract: A dispersing apparatus that can efficiently disperse agglomerated particles in a slurry at a lower energy, a method for preparing a ceramic slurry containing ceramic particles that have been dispersed with the dispersing apparatus, a reliable monolithic ceramic electronic component manufactured using ceramic green sheets formed of the ceramic slurry, and a method for manufacturing the monolithic ceramic electronic component. A slurry containing agglomerated particles is passed through a dispersing section to produce a tensile stress, and the tensile stress is applied to the agglomerated particles in the slurry, thereby dispersing the agglomerated particles. The dispersing section includes a nozzle, a first channel thorough which a jet generated through the nozzle passes, and a cylindrical second channel through which the jet coming through the first channel passes to produce a tensile stress.

  • Patent number: 6579394
    Abstract: A method of producing ceramic slurry capable of producing uniformly dispersed ceramic slurry without excessively damaging a ceramic powder, and a method of producing a ceramic slurry composition used for producing a multilayer ceramic electronic part, from which an undissolved binder is precisely removed. Also provided is a method of producing a ceramic green sheet, and a method of producing a multilayer ceramic electronic part. A ceramic powder having an average particle diameter of about 0.01 to 1 &mgr;m is mixed with a dispersion solvent (solvent) and disintegrated by a medium-type dispersion method using a dispersion medium such as balls, beads, or the like to obtain mixed and disintegrated slurry, followed by high-pressure dispersion under a pressure of about 100 kg/cm2 or more.

  • Patent number: 5358163
    Abstract: A roll body has inside a plurality of suction holes extending along the axis of the roll body such that the suction holes make a concentric circle within the roll body and has a large number of pores connecting each suction hole with the circumferential surface of the roll body. A shaft protrudes from the roll body at one side, and the shaft is covered with a housing. The housing is connected with a vacuum suction device, and the air pressure in the housing is negative. In the housing, ends at one side of the suction holes reach the circumferential surface of the shaft, and a belt is wound around the shaft. While the roll body is rotating to convey a strip wound therearound, the belt wound around the shaft opens the ends of suction holes which communicate with pores being in contact with the strip and closes the ends of suction holes which communicate with pores being out of contact with the strip.
