Method of producing optical film, optical film, polarizer plate, transfer material, liquid crystal display device, and polarized ultraviolet exposure apparatus

InactiveUS20080055521A1High productivityExcellent in optical characteristic and strength of filmPolarising elementsRadiation therapyPolarizerChemistry
A novel method of producing an optical film is disclosed. The method comprises steps (1) to (3) in this order: (1) preparing, on a surface of an alignment film, a layer of a polymerizable composition comprising a polymerizable liquid crystal compound and a dichroic polymerization initiator; (2) aligning molecules of said polymerizable liquid crystal compound in said layer in a first alignment state; and (3) irradiating said layer with polarized ultraviolet light to carry out polymerization of said polymerizable liquid crystal compound and fix molecules of said polymerizable liquid crystal compound in a second alignment state thereby to form an optically anisotropic layer, wherein a percentage of polarized ultraviolet light having an extinction ratio ranging from 1 to 8 is not greater than 15% with respect to an energy density of polarized ultraviolet light per unit area (J / cm2).

Welding device

A welding device includes a welding torch, a memory, a power supply, an input section, a selector, and a controller. The welding torch includes a welding tip having a feeder for supplying electric power to a welding wire. The memory stores a plurality of welding conditions in which a feeder-work-piece to be welded distance is associated with at least one a length of the wire supplied per unit time, a weight of the wire supplied per unit time, and a set electric current. The power supply supplies electric power between the wire and the work-piece. The input section receives an input of a set value of a feeder-work-piece distance. The selector selects one of the welding conditions stored in the memory based on the set value. The controller controls the power supply based on the welding condition selected by the selector.

Bead feeder

InactiveUS20120222597A1Smoothly deliverStable deliveryAutomatic machinesEngineeringSewing machine
A single bead-shaped piece fed from a storage pipe storing therein a large number of bead-shaped pieces is carried not on a bearing plate but on a support member provided independently from the bearing plate. The support member is arranged movable on the bearing plate in conjunction with forward and backward movement of a feeding member, and also arranged to be moved relative to the feeding member at the time of the forward or backward movement thereof. The support member is provided with a clamping section for clamping the bead-shaped piece, which is adapted to clamp the bead-shaped piece in conjunction with the relative movement of the feeding member and the support member. This permits the bead-shaped piece to be delivered properly from the storage pipe to the sewing position in a stable manner, and hence a sewing machine can reliably sew the bead-shaped piece on a sewing material.

Container Carrying Equipment

A container 3 airtightly stores articles, such as semiconductor wafers and liquid-crystal display panels, which are required to be transported with their surface kept uncontaminated. A container transport apparatus is used to transport the container 3 between a plurality of processing apparatuses 1-n within a bay area. The container transport apparatus includes a conveyor 5, which is arranged in a ceiling space within the bay area along a direction of arrangement of the plurality of processing apparatuses 1-n and which is adapted to move the container 3 in a state where the container 3 is placed on a pallet 6. The container transport apparatus also includes a lifting apparatus 7, which is provided for each load port 4 of the plurality of processing apparatuses 1-n disposed under the conveyor 5 and which is adapted to lift and lower the container 3 between the load port 4 and the conveyor 5, and a pallet insertion / removal means 20 for inserting the pallet 6 into a space above the conveyor 5 and removing the pallet 6 therefrom.

Controller for use with gas turbine engine

Provided is a controller for use with a gas turbine engine, which ensures a stable combustion regardless of the deterioration of the catalyst and elevated characteristics of the exhaust gas. The controller 6 is used in the engine which comprises a combustor 2 for combusting a mixture of compressed air from a compressor 1 and a fuel under the existence of catalyst, the combustor having a catalytic combustion unit 21 bearing the catalyst and a pre-burner 7 provided on an upstream side of the catalytic combustion unit with respect to a flow of the compressed air for supplying and combusting a pre-heating fuel PF with the compressed air CA. The controller comprises a memory 6c for memorizing an initial temperature difference D between inlet and outlet temperatures t1, t2 measured at inlet and outlet of the catalytic combustion unit with non-deteriorated catalyst accommodated therein, and a pre-burner control for calculating a present temperature difference between the inlet and outlet temperatures measured in an operation of the gas turbine engine and controlling an amount of the fuel to be supplied to the pre-burner according to a deterioration Δd of the catalyst which is provided by a difference between the initial and present temperature differences D and d.

Steering wheel

The steering wheel includes a wheel body and an airbag apparatus disposed on top of a boss. The wheel body is divided into a shaft side division joined to the steering shaft, and a ring side division disposed proximate the ring. The ring side division is rotatable with respect to the shaft side division such that a ring plane is aligned generally vertically. The boss includes an actuator that rotates and moves the ring side division to align the ring plane generally vertically. The actuator completes its operation to align the ring plane generally vertically by the time a driver contacts the inflated airbag in the course of forward motion.
