Abstract: A projector and an aspherical mirror are arranged below a top of a desk. Lights outputted from the projector are reflected on the mirror and projected on a screen in front of the desk. The reflected lights by the mirror transmit a transparent plate arranged in a part of the top of the desk. The reflected lights can be adjusted to pass in front of the desk. The projector is movable to be contained directly under the desk. The desk is provided with casters, therefore distance between the desk and the screen is adjusted to thereby enlarge the size of a projected picture on the screen.

Abstract: A pre-connectorized loose tube cable protects the optical fibers as the fibers are being routed from the end of an outer sheath to the fiber distribution shelf. The pre-connectorized loose tube cable has a plurality of flexible tubes which are connected to a respective plurality of buffer tubes. The flexible tubes are securely attached to the ends of the buffer tubes and to the pre-connectorized loose tube cable by a capping epoxy and by heat shrinks. The flexible tube has a wall thickness which is greater than the minimum bend radius for the fibers. With such a wall thickness, the fibers are not bent past their minimum bend radius, and thus do not break, even if the flexible tube is bent up to an angle of one hundred eighty degrees.

Abstract: A holder for a plurality of fibers has a top wall, a bottom wall, and first and second side walls. The top wall is preferably releasably hinged to one of the two side walls so that the plurality of fibers may be contained within the holder. The fibers are maintained in a certain order within the holder by selecting the spacing between the two side walls to be greater than the outer diameter of the cables but less than twice the outer diameter of the cables. In this manner, two adjacent fibers cannot switch places with each other within the holder. The holder may have one or more intermediate walls positioned between the two side walls to divide the plurality of fibers into two or more groups. By maintaining the fibers in a fixed certain order, the fibers cannot become intertwined with each other and the chance that the fibers become bent is reduced. Since the chance that the fibers become bent is reduced, the risk of fiber breakage or signal loss is also reduced.

Abstract: A heat resistant cloth for fire fighting comprises a rubber layer, a bonding layer containing a flame retardant, a polyester film with a metallic (e.g. aluminum) film deposited on both sides thereof, a bonding layer containing flame retardant, and a tetrafluoroethylene copolymer film which are layered and bonded together on a substrate fabric. The flame retardant contained in the bonding layers provides excellent flame resistance.

Abstract: A semiconductor device has a thin-film resistor trimmed by laser. The semiconductor device comprises a semiconductor substrate having an element region that covers at least part of the surface of the semiconductor substrate, a first insulation film disposed on the surface of the semiconductor substrate, and a second insulation film disposed on the surface of the semiconductor substrate through an opening of the first insulation film. The opening is formed by selectively removing at least part of the first insulation film at a location on the surface of the semiconductor substrate where the element region is not involved. The thin-film resistor is formed on the second insulation film.

Abstract: A multicore optical connector includes a connector body having a pair of alignment pin holes and a plurality of optical fiber holes formed therebetween and optical fibers inserted in the optical fiber holes such that the end faces of the optical fibers are exposed through the optical fiber holes. In the multicore optical connector, the optical fiber holes are divided into optical fiber hole groups of a number which coincides with the number of the groups of the optical fibers, and the optical fiber hole groups are separated from one another.

Abstract: A method for stacking ferrules of a stacked-type optical connector wherein stacking portions for stacking are provided in corresponding positions of each ferrule, the individual ferrules are stacked with the corresponding individual stacking portions aligned, and a plurality of ferrules are simultaneously stacked up with stacking members which work in cooperation with those corresponding stacking portions in such a manner that the ferrules can practically float with a specific degree of freedom to allow a gap between the ferrules, and a stacked-type optical connector assembled according to this method.

Abstract: A ticket issuing machine having a stocker for containing a continuous form, a paper carrier device for carrying the continuous form supplied from the stocker to an inlet of a carrier line, a paper separating device for separating the continuous form at a score thereof in the carrier line, and a printing/recording device for printing or recording data on the continuous form. The paper separating device includes a blade retained so as to be movable toward and away from a score formed in the continuous form, which blade has a rounded bursting portion adapted to face the score, and a blade driving mechanism for driving the blade so as to bring the blade into abutment against the score for separation of the continuous form at the score. Accordingly, the continuous form can be reliably separated at the score with a small force.

Abstract: The stacker for stacking sets of cards comprises a container for receiving a set of boarding passes and a stacking section for stacking these boarding passes in the container in the fixed orientation. In the stacker, the container has first and second walls opposing each other, and the stacking section includes a first ejecting portion for ejecting the boarding pass into the container from the second wall side, such that front of the boarding pass faces the first wall, a second ejecting portion for ejecting the boarding passes into the container from the first wall side, such that the back of the boarding pass faces the second wall, and a feeder for supplying the passes to one of the first and second ejecting portions sequentially.

Abstract: A liquid detergent composition for household use is disclosed. It comprises, as essential components, (A) 0.01-1.0% by weight of an anionic surface active agent, (B) 0.01-1.0% by weight of a terpene-type hydrocarbon solvent selected from monoterpenes and sesquiterpenes, and (C) 0.001-0.1% by weight of a water-soluble divalent metallic salt. The composition has superior detergency, exhibits a minimum adverse effect on surfaces which it contacts and a high degree of safety when in contact with the human body, and does not require rinsing.

Abstract: A plastic lens formed from a copolymer of three components. A first component which is a vinyl monomer having a nucleus-halogen-substituted aromatic ring. A second component which is selected from at least one member of the group consisting of aliphatic diacrylate, dimethacrylate, triacrylate, and trimethacrylate. A third component is chosen from mono-acrylate or mono-methacrylate having a nucleus-halogen substituted aromatic ring. The components are present in the weight ratio of 20/15/0 to 85/80/60 weight percent, respectively.
