Abstract: A dump truck includes: a main frame that extends in a front-back direction of a vehicle body; an engine installed on the main frame; an exhaust aftertreatment device that is supported by the main frame and purifies exhaust gas from the engine; and a communication pipe having a first end connected to the engine and a second end connected to the exhaust aftertreatment device, in which the exhaust gas discharged from the engine flows to the exhaust aftertreatment device. The communication pipe includes: an upstream pipe extending from the engine to a lateral side thereof; a bellows pipe angularly connected to the upstream pipe and extending in an up-down direction; and a downstream pipe angularly connected to the bellows pipe.

Abstract: A dump truck includes: a main frame; an engine installed in the main frame; and an exhaust aftertreatment device that purifies exhaust gas from the engine. The main frame includes a vertical member in a portal shape which projects in a vehicle height direction of the dump truck and extends in a vehicle width direction of the dump truck. The exhaust aftertreatment device is supported by the vertical member. With this arrangement, maintenance of the engine can be conducted while the exhaust aftertreatment device is kept attached to the vertical member.

Abstract: The present invention aims at providing a biometric identification system and a biometric identification method capable of improving accuracy of verification in a biometric identification by registering plural pieces of bioinformation suitable for the verification.

Abstract: An object of the present invention is to provide an electronic apparatus which can imitate a virtual character and in which others than a user can have communication with the virtual character so that the user can enjoy using the electronic apparatus together with the others. Input image information input through an image pickup portion (5) is compared with user's face image data or face feature data stored in a registered dictionary in anon-volatile memory (4), so as to generate response information. The registered dictionary includes partial region image data or feature data of each face part. The response information is generated based on similarity between image information of each face part extracted from the input image information and the registered dictionary. The response information is output to a display portion (6) as information imitating a behavior of the virtual character.

Abstract: A process for producing an aminophosphoric acid-type chelate resin, which comprises aminating halomethyl groups of a polymer having the halomethyl groups on aromatic nuclei, followed by phosphomethylation, wherein the amination reaction is conducted by means of an amine mixture comprising a monoamine and a polyamine, wherein the proportion of the monoamine to the total amount of both amines is from 20 to 70% by mole.

Abstract: A composite separating agent which comprises a hydrophilic polymer separating agent showing a degree of swelling in water of 10 to 100 ml/g-dry and having a giant network structure incorporated within pores of an organic polymer substrate showing a degree of swelling in water of 20 ml/g-dry or below and a degree of crosslinking of 4% to 100% by mol and having a porous structure as well as a process for producing the same are disclosed.When packed within a column, this composite separating agent having a high mechanical strength is hardly compacted and exhibits an excellent separation performance. Thus it is highly useful in chromatographic separation of biopolymers including proteins.
