摘要:
To provide a mold clamping apparatus able to suppress spout of a molding material from between mating faces of dies and to extend the lifetime of the dies. A mold clamping apparatus has a control apparatus deciding a distribution of a load divided by a plurality of tie bars based on information concerning to the die and controlling pressure of driving oil of a cylinder chamber of each cylinder for mold clamping independently to become a load having a determined distribution.

A molding machine able to detect a burr or other abnormality by detecting the position of tie bars. A control device detects an occurrence of burrs according to whether or not displacement amounts of pistons associated with the tie bars, using position sensors which detect the position of the pistons. The position sensors detect position from the start of injection to the completion of the injection to determine whether detected values are within a permissible range.

According to the present invention, a metal nanoparticle dispersion suitable to multiple layered coating by jetting in the form of fine droplets is prepared by dispersing metal nanoparticles having an average particle size of 1 to 100 nm in a dispersion solvent having a boiling point of 80° C. or higher in such a manner that the volume percentage of the dispersion solvent is selected in the range of 55 to 80% by volume and the fluid viscosity (20° C.) of the dispersion is chosen in the range of 2 mPa·s to 30 mPa·s, and then when the dispersion is discharged in the form of fine droplets by inkjet method or the like, the dispersion is concentrated by evaporation of the dispersion solvent in the droplets in the course of flight, coming to be a viscous dispersion which can be applicable to multi-layered coating.

The ridge semiconductor laser is a semiconductor laser in which a carrier stopper layer made of an AlInAs compound, a clad layer made of an AlGaInAs compound, and an etching stopper layer made of an InGaAsP compound are stacked in sequence on one side of an active layer made of an AlGaInAs compound. The ridge semiconductor laser is provided with a ridge waveguide including, in a layer made of an InP compound, a diffraction grating made of an InGaAsP compound on the opposite side of the clad layer of the etching stopper layer.

An image forming apparatus includes an image forming mechanism and an image fixing unit. The image forming mechanism forms a toner image on a recording sheet. The image fixing unit fixes the toner image onto the recording sheet. The image fixing unit includes a magnetic flux generator, a heat member, a magnetic flux adjuster, and a controlling member. The magnetic flux generator generates a magnetic flux. The heat member is heated inductively by the magnetic flux generated by the magnetic flux generator. The magnetic flux adjuster reduces the magnetic flux active on the heat member to form a heat reduction area in an outer circumferential surface of the heat member in a width direction thereof. The controlling member moves the magnetic flux adjuster to change the heat reduction area.

An optical alignment method which develops a pretilt angle by batch plane exposure without tilting a substrate. This optical alignment method provides liquid crystal aligning capability to the surface of a polymer film by exposing the surface of the polymer film through a slit exposure mask while the surface of the polymer film and the slit exposure mask are moved relative to each other substantially at a fixed rate. Alternatively, liquid crystal aligning capability is provided to the surface of the polymer film by exposing the surface of the polymer film through an optical exposure pattern while the optical exposure pattern having a plurality of lines with a certain width at certain intervals is formed on the surface of the polymer film continuously.

A method for removing a casted part, for use in a die casting machine comprises the steps of setting a position in which a chuck performs an operation to grasp a casted part attached to a movable mold as a position from which the casted part is to be removed, and setting a relative positional relationship between a handle portion which is a part of the casted part attached to the movable mold to be grasped by the chuck and a movable die plate. The method further comprises the step of advancing the chuck between the movable mold and the fixed mold and positioning the chuck at the position from which the casted part is to be removed, in parallel with the movement of the movable die plate. Additionally, the method comprises the steps of stopping the movable die plate when the handle portion of the casted part attached to the movable mold reaches the position from which the casted part is to be removed, grasping the handle portion of the casted part by using the chuck, and removing the casted part from the movable mold.
