Abstract: Provided are heat-expandable microspheres which have high expansion performance to exhibit highly thermoresponsive expansion behavior in short heating time and the application thereof. The heat-expandable microspheres are composed of a thermoplastic resin shell and a blowing agent encapsulated therein and vaporizable by heating. The thermoplastic resin is a polymer of a polymerizable component containing a nitrile monomer, and the nitrile monomer contains acrylonitrile and methacrylonitrile in a ratio of 100 parts by weight/40 parts by weight to 80 parts by weight. The blowing agent contains a blowing agent (a) having a specific heat in the range from 0.8 J/g·K to 2.0 J/g·K. Also disclosed is a composition containing the heat-expandable microspheres and a formed product manufactured by forming the composition.

Abstract: A work inspection system 2 includes: a conveyor table 7 vertically positioned, and conveying works W stored in work-storing pockets 9; a work inspection apparatus for inspecting the works stored in the work-storing pockets 9 of the conveyor table 7; and a sorting and ejecting apparatus 12 for sorting the inspected works stored in the work-storing pockets of the conveyor table in accordance with a property of the works and ejecting the same. The work-storing pockets 9 of the conveyor table 7 are positioned inside the periphery 7a of the conveyor table 7 to surround the works W. The work-storing pockets 9 are disposed along two concentric circles on the conveyor table 7.

Abstract: This invention provides joining methods of single veneer piece and a joining apparatus, which can produce more efficient, and effective joining process than the conventional method and apparatus produce. In the process of carrying a single veneer piece (T) in the orthogonal direction against the joining edge (Te) on the conveyor, the joining edges of the preceding and succeeding single veneer pieces come close together, the adhesive material (Sd) is supplied to the clearance between the joining edges, and then the adhesion enhancing action is supplied to the said adhesive material (Sd) to join each single veneer piece (T) successively. The adhesion enhancing action can be applied within the adhesion enhancing section as indicated by lines (Z1) and (Z2), provided on the farther side from the edge approaching position (U) via an adhesion enhancing component (6) to move back and forth at any time while the single veneer piece (T) is being carried or such a motion is halted.

Abstract: An apparatus for and a method of bonding veneers without problems in manufacturing process even if logs, which causes disorder of veneers after dried are used. The veneer bonding apparatus for bonding veneers to each other comprises: a bonding face machining device for machining both end portions of a veneer to be bonded to bonding faces; a bonding agent applying device for applying bonding agent to at least one bonding face of the machined bonding faces; an adjusting device for adjusting a front end bonding face of a succeeding veneer to a rear end bonding face of a preceding veneer such that a face side of the preceding veneer with the applied bonding agent and a backside of the succeeding veneer with the applied bonding agent are flush with each other; and a pressurizing device for pressurizing the adjusted bonding faces to each other.

Abstract: A belt conveyor is provided to feed veneers in the arrow-marked direction in the drawing. A porous transfer belt having numerous of air holes therein is stretched around so as to run above said belt conveyor. Inside the porous transfer belt, a suction hood which has a plurality of small air passages formed in the running direction of the porous conveyor belt is installed to rotatably accommodate a damper further therewithin. The damper makes intermittent rotations to open or close the sucking section such that only a desired veneer is selectively sucked for sort-out transfer with the result that the need for piercing the veneer or defining in advance a gap between each adjacent two veneers is eliminated. Therefore, it is now possible to perform high speed sort-out operations without subjecting the veneer to damage or breakage resulting from tensile strength exerted thereon at the time of defining the gap.
