Abstract: In a robot control system, the operation of a mobile robot that moves autonomously inside a facility is controlled based at least on an image captured by a photographing device that photographs a blind area located at a blind angle to the mobile robot. When entry of the mobile robot into a predetermined area corresponding to the blind area is detected, the amount of information obtainable from an image captured by the photographing device is increased.

Abstract: A mobile robot receives first transmission information transmitted from a server device to manage the mobile robot in a state where wireless communication with the server device is possible, directly executes wireless communication with another mobile robot among the mobile robots and executes a reception process of receiving the first transmission information transmitted from the server device to manage the mobile robot from the other mobile robot in a case where wireless communication with the server device is not possible.

Abstract: A robot control system according to the present embodiment is a robot control system that controls a plurality of mobile robots that can autonomously move in a facility. The robot control system acquires error information indicating that an error has occurred in a first transport robot, acquires transported object information related to a transported object of the first transport robot, determines a second transport robot able to transport the transported object of the first transport robot among the transport robots based on the transported object information and the error information, and moves the second transport robot to a transfer location of the transported object of the first transport robot.

Abstract: An antistatic resin-made container is formed by solution-bonding a plurality of resinous parts thereof to each other, preferably with acetonitrile as the solvent, wherein each resinous part is formed of an antistatic resin composition including (a) a polyacrylonitrile resin: 50-95 wt. % and (b) a hydrophilic polymer: 5-50 wt. %. The thus-formed antistatic resin-made container is suitable for accommodating a precision product, such as a photomask, or a semi-product thereof, which is produced in an extremely small number but requires a high level of antistatic property of the container therefor.

Abstract: A relatively light resinous hermetically sealed container for a large-sized precision sheet (semi-)product, such as a photomask, is provided so as to accommodate, support and transport the precision sheet (semi-)product safely and in an airtight manner. The hermetically sealed container includes a main body and a lid member respectively having peripheral flange portions abutted to each other so as to accommodate a precision sheet (semi-)product therein. Each of the main body and the lid member is formed as a vacuum or air-pressure formed thermoplastic resin sheet equipped with a reinforcing rib.

Abstract: A relatively light and generally resinous hermetically sealed container is provided for accommodating, supporting and transporting a precision sheet (semi-)product, such as a photomask, safely and in an airtight manner without exerting an inappropriate stress thereto, which precision sheet (semi-)product has such a large planar size that encounters an extreme difficulty in integral resin molding of a half of a container therefor. The container includes a main body and a lid member which are generally symmetrical with each other and respectively have sealing peripheries to be abutted to each other. Each of the main body and the lid member includes a plurality of resin-sheets which are disposed in a plane, abutted to each other at an intermediate joint boundary therebetween and joined with each other at the joint boundary. A reinforcing metal belt member is disposed from outside along the joint boundary and hermetically bolted to the resin sheets.

Abstract: A small account of polyvalent metal compound is added to an antistatic resin composition comprising a hydrophilic thermoplastic polymer. A shaped product of the resin composition retains permanent antistatic property and a beautiful appearance due to not only freeness from attachment of dust, etc., but also suppression of haze or discoloration caused by attachment of a gaseous soiling substance, such as an acidic and a basic gas in the air. The resin composition also provides a shaped container product free from occurrence of attached substance on an electronic part or optical part even when the part is subjected to irradiation with ultraviolet light after storage in the container product.

Abstract: A thermoplastic resin composition is formed by mixing (A) 30-84.9 wt. % of a crystalline thermoplastic resin, (B) 15-65 wt. % of a graft copolymer obtained by graft-polymerizing an ethylenically unsaturated monomer onto a rubber trunk polymer having an alkylene oxide group and (C) 0.1-5 wt. % of an anionic surfactant. As a result, it is possible to obtain a non-black thermoplastic resin composition which shows an antistatic property at a level suitable for use as an ESD (electrical static dissipative) and can be colored into arbitrary hues.

Abstract: An anionic surfactant having a thermal weight loss initiation temperature of at least 250° C. is incorporated with a thermoplastic resin comprising a graft copolymer formed by graft-polymerizing an ethylenically unsaturated monomer onto a rubber trunk polymer obtained by emulsion polymerization using a carboxylic acid-type surfactant. As a result, it is possible to obtain an antistatic resin composition which can be effectively produced on an industrial scale and can provide a shaped product excellent in permanent antistatic property and free from haze or discoloration even when processed under severe processing conditions.
