Abstract: An optical disk having high density and excellent quality as well as compatibility with conventional disks is provided. This optical disk is comprised of a disk-shaped substrate formed with a cyclic olefin polymer as its main component and a light-curing resin layer formed on the disk-shaped substrate, wherein a pattern is formed on the light-curing resin layer based on given information. The same effect can be obtained using a heat-curing resin in place of the light-curing resin. Optical disks having superior characteristics can be mass-produced.

Abstract: The object is to make a color filter smoothly. It includes a step of causing a discharge in a gas atmosphere including oxygen at atmospheric pressure and treating a substrate (10) by means of the activated species; and a step of injecting ink of predetermined color in ink filling concavities (29) in a predetermined layout formed on a template (13) to form a color pattern layer (14), next adhering the substrate (10) to the template (13) having the color pattern layer (14) formed thereon with a resin layer (15) interposed therebetween, and then separating the color pattern layer (14), resin layer (15), and substrate (10) as one from the template (13).

Abstract: A process of making a color filter includes a first step of producing a master having a plurality of ink charging recesses arranged in a given pattern, a second step of charging ink of preselected colors into the ink charging recesses to form an ink layer, a third step of forming a resin layer over the master into which the ink have been charged and a fourth step of separating the ink layer and the resin layer together from the master after these layers have been cured.

Abstract: A material for spacecrafts pertaining to this invention is made of a compound containing the group IV b elements, as a material of which proof for oxygen atom is absolutely necessary. The application of this material, in the form of a shield part (a resin layer) for covering at least a portion of material used in a structural part of the spacecraft enables a long use (from several months to several decades or more) in the oxygen atom environment in the space, which was impossible in the part.

Abstract: An apparatus for classifying particles entrained by a solid-gas jet stream includes a feed nozzle, a cyclonic wall having an inner arcuate wall, and an auxiliary inner arcuate wall provided at an outlet port of the nozzle. The solid-gas stream is preliminarily bent along the auxiliary inner wall so that the particles are preliminarily or roughly classified into undersized and oversized particles by the action of the centrifugal force before they are classified by the cyclonic wall. The apparatus may include a collecting port disposed downstream of the nozzle outlet port and spaced slightly away from the inner arcuate wall of the cyclonic wall. The collecting port permits the apparatus to collect the undersized particles in a more effective manner.

Abstract: A tractor cabin having struts, a top framework, an air conditioner mounted on the top framework, and a ceiling assembly covering an entire ceiling area of the cabin. In order to optimize air conditioned flows, the ceiling assembly includes outlet vents in a front region thereof for delivering defrosting air flows, outlet vents in lateral sides thereof for delivering air flows for the driver, an inside air intake vent in a rear portion thereof inside the cabin, and an outside air intake vent rearwardly and outwardly of the cabin. The ceiling assembly further includes an overhead console box having an air conditioning control unit and other elements. The console box is disposed such that its lower end is on or above a straight line extending from the driver's eye level to the top edge of a windshield to provide the driver with an unobstructed forward view.

Abstract: A transmission comprising a main change speed mechanism, an auxiliary change speed mechanism, a rear differential mechanism and a cassette type supplementary change speed mechanism. The supplementary change speed mechanism acts on the transmission through an opening defined in a transmission case housing the transmission. The supplementary change speed mechanism is housed in and supported by a supplementary change speed case which is attached to the transmission case. Transmissions of various specifications may be provided by making various types of supplementary change speed mechanism. The supplementary change speed mechanism is applicable to a propelling transmission line and/or a power takeoff transmission line.

Abstract: A tractor cabin having a pair of right and left front struts, a pair of right and left rear struts, a pair of right and left intermediate struts disposed between the front and rear struts, a top frame interconnecting upper ends of the front, rear and intermediate struts, a floor sheet attached to lower ends of the front, rear and intermediate struts, and a gate-shaped cabin front defined by the front struts and the top frame. The cabin comprises a gate-shaped partition assembly disposed at a lower mid-position transversely of the cabin front, connecting members connecting right and left lower ends of the partition assembly to lower ends of the right and left front struts, and a transparent member secured to inner peripheries of the cabin front, the transparent member including side transparent portions extending downwardly therefrom.

Abstract: A fabric of cellulosic fibers, particularly natural cellulosic fibers, of improved dyeability having a polymer of a monomer containing a quarternary amine group dispersed in the fibers with no phase separation is discharge printed. The improved cellulosic fibers can be prepared by impregnating a monomer containing a quarternary amine group into cellulosic fibers and polymerizing the monomer in the fibers. This treatment of cellulosic fibers with the polymer of a quarternary amine monomer can be advantageously utilized in the discharge printing of a fabric from a blend of hydrophobic synthetic/cellulosic fibers.
