20120192762 | METHOD FOR PRODUCING FINE MESOPOROUS SILICA PARTICLES, FINE MESOPOROUS SILICA PARTICLES, LIQUID DISPERSION OF FINE MESOPOROUS SILICA PARTICLES, COMPOSITION CONTAINING FINE MESOPOROUS SILICA PARTICLES AND MOLDED ARTICLE CONTAINING FINE MESOPOROUS SILICA PARTICLES - Fine mesoporous silica particles are provided by which not only the functions of low reflectance (Low-n), low dielectric constant (Low-k) and low thermal conductivity but also improved strength of a molded article are achieved. The fine mesoporous silica particles are manufactured by a process including a surfactant composite fine silica particle preparation step and a mesoporous particle formation step. In the silica fine particle preparation step, a surfactant, water, an alkali and a hydrophobic part-containing additive including a hydrophobic part for increasing the volume of micelles are mixed with a silica source to thereby prepare surfactant composite fine silica particles. In the mesoporous particle formation step, the mixture is mixed with an acid and an organosilicon compound to thereby remove the surfactant and hydrophobic part-containing additive from the surfactant composite fine silica particles and provide the surface of each silica fine particle with an organic functional group. The fine mesoporous silica particles have mesopores inside each particle, and are modified on the surface with organic functional groups. | 08-02-2012 |
20130267629 | MESOPOROUS SILICA PARTICLES, METHOD FOR PRODUCING MESOPOROUS SILICA PARTICLES, AND MESOPOROUS SILICA PARTICLE-CONTAINING MOLDED ARTICLE - The mesoporous silica particles each comprise a core particle comprising first mesopores, wherein a periphery of the core particle is covered with silica. Preferably, second mesopores, smaller than the first mesopores, are provided in the silica-covered part formed by the silica covering. The mesoporous silica particles are produced by: a surfactant complex silica particle preparation step of mixing a surfactant, water, an alkali, a hydrophobic part-containing additive and a silica source to thereby prepare surfactant complex silica particles, said hydrophobic part-containing additive including a hydrophobic part for increasing a volume of micelles to be formed by the surfactant; and a silica covering step of adding the silica source to the surfactant complex silica particles to thereby cover a periphery of each core particle with silica. | 10-10-2013 |

20130057310 | HANDLER AND PART INSPECTION APPARATUS - A handler includes a base having an opening portion, a first hand which transports a transport target, a first transport section which transports the first hand to above the opening portion and moves the first hand down, a second hand which transports the transport target, a second transport section which transports the second hand to above the opening portion and moves the second hand down, and a control section which controls an operation of the first transport section and an operation of the second transport section. The handler has a state where the first hand and the second hand are disposed in parallel to the opening portion while being close to each other toward above the opening portion. | 03-07-2013 |
20130058741 | HANDLER AND PART INSPECTION APPARATUS - A handler includes at least one transport section which transports a transport target onto a base. The transport section includes a plurality of first elevating sections which respectively move up and down a plurality of gripping sections which grip the transport target, and a single second elevating section which moves up and down all the plurality of first elevating sections. In connection of the transport target to a connection destination, a part of the plurality of first elevating sections are driven to descend, and the remaining part thereof are driven to ascend. | 03-07-2013 |
20130205804 | HANDLER AND PART INSPECTING APPARATUS - A handler includes a storage tank which stores liquid nitrogen, supply channels which supply refrigerant from the storage tank to inner passages of a first shuttle, a valve which opens and closes the supply channel, and a heat exchanger which has vaporization chambers with larger flow path cross-sectional areas than those of the supply channels to vaporize liquid nitrogen within the vaporization chambers. According to this structure, the respective vaporization chambers are filled with nitrogen gas produced by preceding vaporization. Thus, pressure fluctuations produced by successive vaporization of liquid nitrogen can be reduced. Moreover, nitrogen gas is supplied to the respective inner passages. Accordingly, excessive cooling for part housing pockets can be prevented. | 08-15-2013 |
20130206383 | HANDLER AND PART INSPECTING APPARATUS - A handler includes a first cooling channel and a second cooling channel corresponding to housing pockets, a first supply channel, a second supply channel branched from the first supply channel, a first throttle valve which controls the flow of refrigerant such that the flow amount of the refrigerant flowing through the second cooling channel becomes larger than the flow amount of the refrigerant flowing through the first cooling channel, heaters which heat the respective housing pockets, temperature sensors which detect the temperatures of the respective housing pockets, and a control device which controls the opening and closing condition of a valve and the output of the heater, and controls the output of the other heater such that the detection values of the respective temperature sensors become a target temperature. | 08-15-2013 |
20130209199 | PART INSPECTION APPARATUS AND HANDLER - A handler includes a supply shuttle plate on which a device is placed and cooled, and a transfer robot configured to transfer the device placed on the supply shuttle plate from the supply shuttle plate. The transfer robot includes an adsorbing portion configured to adsorb the device placed on the supply shuttle plate thereon, a vertical movement arm configured to move the adsorbing portion away from the supply shuttle plate, an arm box configured to accommodate the adsorbing portion together with the device in a state of being kept away from the supply shuttle plate, and a dry air supply unit configured to supply dry gas into the arm box. | 08-15-2013 |
