There is provided a laser machining apparatus, and a laser machining method using the same. The laser machining apparatus has a body portion having a plurality of laser irradiating sections and work mounting sections, a supplying stocker for supplying workpieces, and a discharging stocker for discharging the workpieces. The apparatus further comprises a supply-side transfer unit having work retaining tables capable of attracting/releasing the workpieces and being of the same number as the laser irradiating sections, and moving in vertical and horizontal directions, and a discharge-side transfer unit having work retaining tables capable of attracting/releasing the workpieces and being of the same number as the laser irradiating sections, and moving in vertical and horizontal directions. The supply-side transfer unit causes the supply-side work retaining tables to attract the workpieces from the supplying stocker one after another and moves these supply-side work retaining tables to the work mounting sections to place the workpieces thereon. The discharge-side transfer unit causes the discharge-side work retaining tables to attract the work pieces which have been machined at work mounting sections, and to move and discharge these workpieces to the discharging stocker.

An encapsulation method applicable to pharmaceutical preparations, cosmetics, pigment imparting materials such as inks, paints, dyes, electrostatic toner, and others is disclosed, as are methods of use thereof. According to the disclosed method, the use of auxiliary materials such as emulsifiers or surfactants can be dispensed with, and ultramicrocapsules having a readily controllable diameter of 1 .mu.m and less can be produced. The disclosed method includes the steps of preparing an organic phase consisting of a mixture of one or more hydrophobic liquid and/or solid materials and self dispersible resin which through the action of an aqueous phase, self disperses into particles with a diameter of 0.1 .mu.m and less; combining an aqueous phase with the organic phase, whereby self emulsification takes place, thereby encapsulating the one or more hydrophobic liquid and/or solid materials.

An image creating apparatus selectively displays a plurality of scenes on a display unit. The image creating apparatus includes an image-data storage unit including at least three data storage areas in each of which image data of one frame on the display unit are stored, a picture-signal processing unit for generating the image data of one frame and for cyclically storing the generated data in the data storage areas, an image output unit for cyclically reading and successively outputting the image data stored in the data storage areas, a switching-designation unit for outputting a signal for designating the switching of each scene displayed on the display unit, and a processing-control unit for switching the scene being displayed on the display unit from an old scene to a new scene when the switching-designation signal is output. The processing-control unit includes an old-scene holding unit for holding the image data of the old scene in any one of the data storage areas in the image-data storage unit, and an instruction-controlling unit for controlling the picture-signal processing unit to use the images of the old and new scenes to generate image data and to cyclically store the generated image data in the other data storage areas.

An orifice plate is projectingly provided within a fluid chamber formed inside an elastic block to damp the medium to high frequency vibrations. The orifice plate is arranged to have a projection area which is maximum in the principal input direction Z of vibrations to be isolated, medium in the direction Y of the two input directions X and Y which are perpendicular to the direction Z, and minimum in the direction X by providing a recess at a bottom thereof which traverses in the same direction (as the direction X). The resonance frequency is high in the direction Y and the circumferential edge portions of the projection surface in the direction Y are adapted to serve as stoppers which perform the displacement control in the direction X. In another embodiment, the stoppers are asymmetrically shaped.
摘要:
In a method of manufacturing an optical waveguide by the use of a substrate which has a first ion of a first refractive index and primary and secondary surfaces, an optical passage is formed in the substrate by diffusing through the primary surface a second ionizable species of a second refractive index greater than the first refractive index. A diffusion-accelerator layer is deposited on the secondary surface to accelerate diffusion of secondary ions resulting from the second ionizable species. To this end, the diffusion-accelerator layer is composed of an additional ionizable species which is formed into additional ions able to react with the first ions. Such reaction of the additional ions with the first ions lends itself to reduce the amount of the first ions in the substrate and to promote diffusion of the second ions into the substrate.
