| 20080262654 | MANIPULATOR SYSTEM - A manipulator comprises an actuator block and a working unit attachable to and detachable from the actuator block. The actuator block has a motor, the working unit has a connecting shaft and an end working portion disposed at the distal end thereof, and the end working portion is rotated in conjunction with the motor. The working unit further has a two-dimensional code holding an identification signal, and the actuator block further has an infrared camera for recognizing the identification signal in the code and supplying it to a controller, is the camera being not in contact with the code. The controller controls the working unit based on the supplied identification signal. | 10-23-2008 |

| 20090314401 | METHOD OF FABRICATING PNEUMATIC TIRE AND PNEUMATIC TIRE - An object is to reduce a cycle time for fabricating a low rolling resistance pneumatic tire and to provide the same pneumatic tire. As a means therefor, in building a tread portion by winding spirally a rubber strip material whose cross section is divided into a first region made of a conductive rubber and a second region made of a non-conductive rubber in a tire circumferential direction in a partially overlapping fashion by the use of an extruding machine which extrudes continuously the rubber strip material, an area ratio of the first region relative to the cross section of the rubber strip material is made to change in a tire width direction. | 12-24-2009 |
| 20090320985 | RUBBER STRIP MATERIAL - When forming a rubber member which is made up of a combination of a plurality of rubber compounds by winding spirally a ribbon-shaped unvulcanized rubber strip material in an overlapping fashion, the number of times of winding is reduced so as to shorten a fabrication cycle time of the rubber member to thereby increase the productivity thereof. As a means therefore, a rubber strip material whose cross section is divided into two or more regions which are made up of different rubber compounds is wound spirally on to a drum in an overlapping fashion so as to build a green tire or a tire rubber member. | 12-31-2009 |

| 20110126951 | PNEUMATIC TIRE - An object of the present invention is to provide a pneumatic tire which prevents not only partial wear but also clack generation in land portion of tread surface. In order to achieve the object, the land portion is formed with a first type sipe having a step portion extending in a width direction of the tire on one sipe wall surface and a second type sipe having a step portion extending in the width direction of the tire on a sipe wall surface facing in the opposite direction of the first type sipe as viewed in the circumferential direction of the tire. | 06-02-2011 |

| 20110112242 | METHOD FOR PRODUCING DYE POLYMER, DYE POLYMER AND USE OF THE SAME - Disclosed are a production process of a dye polymer having a dye content of from 1 to 50 wt %, and the dye polymer and its use. The production process includes subjecting an addition-polymerizable monomer to living radical polymerization by using, as a polymerization initiator, a dye having a polymerization initiating group enabling the living radical polymerization. The dye polymer and a composition of the dye polymer and a pigment are useful as good coloring agents for various products or articles. The colored products or articles are high in transparency, and are provided with high added value. The dye polymer can also be used as a dispersant for pigments, thereby making it possible to afford pigment dispersions excellent in dispersion properties and dispersion stability. | 05-12-2011 |
| 20110136965 | PIGMENT DISPERSIONS, BLOCK POLYMERS AND MANUFACTURING METHOD THEREFOR - Disclosed is a pigment dispersion containing at least a pigment, a liquid medium and a high-molecular dispersant. The high-molecular dispersant is a block polymer represented by A-B or A-B-C, in which A, B and C each represent a polymer block and the A and C blocks may be the same or different. The block polymer and its production process are also disclosed. The high-molecular dispersant is free of problems of a smell, coloration, a heavy metal and cost, and its use can provide a pigment dispersion excellent in the dispersion stability of a pigment. | 06-09-2011 |
