Abstract: In a casting sand reclamation system and a casting sand reclamation method, an appropriate reclamation process is performed according to the properties of casting sand to improve the reclamation accuracy and the reclamation yield. Capacitance measuring devices 70 and 71 that measure the capacitance of casting sand 1 (recovered sand 1a or reclamation sand 1b) are arranged on an upstream side and a downstream side of a batch-type polishing device 7, and feedback control is performed based on the measurement results of the capacitances by these capacitance measuring devices 70 and 71. A sorting device 10 sorts the recovered sand 1a polished by the polishing device 7 into a sand grain component (reclamation sand) and a fine grain component (containing a binder), and has a capacity N times that of the polishing device 7.

Abstract: A method for manufacturing a concrete structure comprises an installation step of installing a formwork 30 for concrete placement, a placement step of performing concrete placement in a state where a curing sheet 10 is attached to an inner surface of the formwork 30, and a demolding step of removing the formwork 30 after placement of concrete C. A contact angle of a contact surface of the curing sheet 10 for use in the placement step with water is 50 degrees or more, wherein the contact surface faces the concrete. Thus, generation of bleeding water is suppressed.

Abstract: A veneer lathe that can provide a veneer produced by cutting out a log, which is substantially free from surface scratches, and thus can be used as a surface sheet for plywood. A roller bar drives a log while pushing its peripheral surface on the upstream side of a knife fixed to a knife carriage for cutting the rotating log in a log rotating direction. The roller bar 3 has a large number of grooves defined in a peripheral surface thereof. The shape of the grooves 5a in a section crossing the shaft centerline of the roller bar 3 is set so that an angle between a tangent at a corner portion 3e constituted by a line 3d of an outer periphery of the roller bar 3 and a line 3b extending outward from an upstream side face of the grooves 5a is 130 to 160 degrees.

Abstract: The present invention provides a technique of selectively producing a desired polymorph of 2-(3-cyano-4-isobutyloxyphenyl)-4-methyl-5-thiazolecarboxylic acid. The present invention also provides a method of producing various polymorphs of 2-(3-cyano-4-isobutyloxyphenyl)-4-methyl-5-thiazolecarboxylic acid, which comprises crystallizing under the conditions defined by a specific temperature and a composition of a mixed solvent of methanol and water, and polymorphs obtained by the method. The present invention further provides a method of producing the other polymorphs or amorphous compounds by drying a specific polymorph under a reduced pressure with heating, and the other polymorphs or amorphous compounds obtained by the method.

Abstract: A veneer lathe comprising a knife (2) for peeling a log (1), which is secured rotatably to a knife stock, and a roller bar (3) disposed to press a circumferential surface of the log (1) at an upstream side, in relative to said knife (2), of a rotational direction of the log (1). The roller bar (3) has a diameter of not more than 30 mm, and is provided on the circumferential surface thereof with a large number of projections (5) whose height is not higher than the circumferential surface of the roller bar (3). The roller bar (3) is sustained in a sliding bearing (9) and adapted to receive a rotational force from a driving source. The roller bar (3) functions not only as a pressure bar but also as a power transmitting media to rotate the log (1), thereby preventing the generation of lathe check of veneer to be produced.

Abstract: A power unit for a front drive vehicle having a horizontally opposed engine mounted longitudinally, a clutch, a transmission and a differential, in which a differential housing integrally formed with a transmission housing is disposed at a space adjacent to the frontally offset cylinder block of left or right cylinder blocks and a left and right axle shaft is extended from the differential housing respectively. Further, the differential housing is connected by a fastening bolt with a slide bush to a lower case of the engine so as to support the reaction force derived from the axle shafts. The power unit thus constituted offers a short length of a front overhang of the vehicle and the compactness of a power unit.
