Abstract:
A computer graphics apparatus includes a walk-through function to simulate with a computer the concept of walking through a structure such as a building. Display processing time and calculation processing time for one frame of a computer graphic image are improved by an input unit which receives a viewline moving instruction to move a viewline of a computer image. A viewline control unit determines positions and directions of the viewline while a storage unit stores computer graphics data including three-dimensional data of objects, walk-through attribute data and viewline data. An image generation unit then generates images including animated images based on the position of the viewline and the computer graphics data. The resultant images are then displayed on an image display unit.
Abstract:
A thin film magnetic head includes an upper core layer and a lower core layer which are made of an Fe-M-O alloy, an Fe-M-T-O alloy or an NI-Fe-X alloy so that the upper core layer has a high saturation magnetic flux density, low coercive force and high resistivity, and the lower core layer has a lower saturation magnetic flux density than the upper core layer, low coercive force, high resistivity, and a low magnetostriction constant. Also the lower core layer is formed so that the thickness gradually decreases toward both side ends, and a gap layer can be formed on the lower core layer to have a uniform thickness. Since the lower core layer is formed by sputtering, a material having excellent soft magnetic material can be used, thereby enabling recording at high frequency.
Abstract:
In a roller seam welding machine, the upper welding roller is led through a welding-force adjustment device with two spring elements. One spring is already effective when the initial deflection of the welding roller occurs. The other spring comes into operation only when a certain deflection (D) is reached. A marked improvement in weld quality can be obtained in this way, particularly at the start of the weld seam.
Abstract:
A refrigerant distribution unit 10 is an integrated structure comprising: a multiplicity of branch tubes 12a-12c connectable with a multiplicity of indoor units 1a-1c; a distributor 11, connected with one refrigerant tube 5a extending from an outdoor unit for receiving refrigerant from the outdoor unit, the distributor distributing the refrigerant to the multiple branch tubes 12a-12c; and electric valves 15 provided one in each of the branch tubes 12a-12c for controlling the flows of refrigerant that pass through the respective branch tubes; and a case for enclosing the flow control unit. The refrigerant distribution unit 10 enables distribution of optimal amounts of refrigerant to all of the coexisting indoor units 1a-1e, even when the indoor units 1d-1e have much larger heat capacities than the indoor units 1a-1c.
Abstract:
A coating method that is capable of rapid curtain coating without causing "sagging" at high flow rates exceeding 4 cm.sup.3 /cm.sec. One or more layers of a coating solution are formed on a sliding surface, and a free falling curtain of the coating solution is allowed to impinge against a continuously running web. The web has a surface roughness of at least 0.3 .mu.m, the tip of the sliding surface forms an angle of 45.degree. to 120.degree. with respect to the horizontal, and the viscosity of the coating solution is adjusted to at least 90 cps for low shear rate, with the average for all layers formed being at least 80 cps.
Abstract:
A slide-hopper-type coating method in which the viscosity of the coating solution forming a free-falling curtain and the angle .alpha. which the front edge of the lip of the slide hopper forms with respect to the horizontal are selected with respect to the flow rate of the curtain in such a way that the line of contact between the curtain and the web is concave with respect to the direction in which the web travels. In addition, the angle .beta. which the extension of the curtain in the direction of its fall forms with respect to the direction of travel of the web at the point where the curtain is deposited on the web is preferably adjusted so that it is an obtuse angle not larger than 140.degree.. By satisfying these conditions, the coating method of the present invention is capable of extending the upper limit of coating speeds without causing "sagging" in the range of high flow quantities of coating solution per unit length of curtain coat width.
Abstract:
A method for manufacturing a semiconductor device comprises the steps of forming a polysilicon spacer on an after-oxide film on a semiconductor substrate, doping the polysilicon spacer by ion-implanting an impurity such as phosphorus, thermally diffusing the impurity into the polysilicon spacer, and eliminating the polysilicon spacer in part by etching. A semiconductor device manufactured by this method is also disclosed.
Abstract:
An automatic infinitesimal liquid reactor equipped with a pipetter for dispensing reagents employs two stages which are capable of sliding horizontally. A microplate which has a plurality of recesses in rows is placed in one stage and reagent bottles are placed on the other stage. The pipetter is supported on a horizontal guide rail operating slidably horizontally and along an axis perpendicular to the direction in which the two stages slide. The horizontal guide rail is supported on a vertical guide rail so as to operate slidably in a vertical direction. Thus the pipetter can be moved in a plane perpendicular to the direction in which the two stages slide. When reagents are sucked from reagent bottles, the second stage is slid so that a reagent bottle is superposed below the pipetter and the pipetter is moved downwardly into the reagent bottle to draw in a reagent. When the reagent is discharged, the first stage is slid so that the microplate is superposed below the pipetter and the pipetter is moved downwardly into a recess to discharge the reagent, thereby dispensing a reagent efficiently and minimizing the space required for the reactor.
Abstract:
A cleaner wherein the upper surface of a main body is provided with fasteners each of which includes a stopper arm portion which is opened and closed by slidably operating an opening and closing lever that is engageable with sides of the main body, while each side of the main body is provided with a pile composed of short tufts. A cloth having a larger area than that of the bottom of the main body is pierced with the pile to lock the same to the opposite sides of said main body, and the cloth is positively retained on the opposite sides of the main body by the stopper arm portions of the fasteners, so that the bottom of the main body is covered with the cloth.
Abstract:
A touch panel (input device) includes a flexible transparent base; a transparent electrode formed on a first surface of the transparent base; a decorative layer formed on a second surface of the transparent base, the second surface being opposite the first surface; and a transparent panel (glass panel) bonded to the second surface of the transparent base, with an optical clear adhesive layer interposed therebetween.
