Title: Molding board for top pouring ingotting
Inventor: ARISONO YOSHIAKI
IPC: B22D7/06
Filed: 1979-07-25
Abstract: PURPOSE: To enable refractory materials to be firmly bonded by simple work by forming the opposite side wall surfaces on the inside circumference of the recess of a molding board consisting in fitting the molded refractory materials in the central recess into a downwardly divergent taper shape and pressing a pair of refractory materials fitting to this by a wedge-like refractory material.  
     CONSTITUTION: At least a pair of opposite side wall surfaces out of the inside circumferential surface of the recess 2 in the central part of the surface of a molding board 1 are formed by downward divergent tapered surfaces 2a. On the other hand, the wall surfaces on the fitting refractory material pair 3a side are formed into  downwared projecting taper surfaces 3a' opposing to the taper surfaces 2a. A  wedge-like refractory material 3b is wedged between a pair of the refractory materials 3a and both side walls thereof are formed with taper surfaces 3b' for the purpose of driving-in; moreover, taper surfaces 3a" are also formed on the opposite  wall surfaces of the refractory material pair 3a. Hence, the refractory material pair  3a is pushed aside to both sides by wedging-in of the refractory material 3b and  when the wedging-in is completed, the taper surfaces 3a' and 2a are press-welded,  and the refractory materials 3a, 3b firmly fit to one body within the recess 2.

IPC: C09K3/18
Filed: 1995-04-20
Abstract: PURPOSE: To provide a method for making a solid surface water-repellent, whereby the surface layer made of a water-repellent substance applied to the surface can be hardly peeled from the surface when the surface is wiped, and the life during which the surface is kept water-repellent, can be prolonged. CONSTITUTION: The surface of a solid 1 is roughened, and a layer of a solid water repellent 4 is formed over the recesses formed by the roughening. In the surface roughening treatment, a large number of solid fine grains 3 having a diameter of 1-100μm are adhered to the surface with an adhesive 2 so that the grains may be apart from each other by a distance 0.1 to about several times as large as the diameter. This is practiced by bringing the surface into contact with fine grains 3 before the solidification of the surface or by bringing a softening material into contact with the surface, bringing the softening agent into contact with the fine grains 3 and solidifying the surface.

CONSTITUTION:A superconducting stationary energy storage apparatus is composed of an effective-power controller 1A, of a reactive-power controller 2A, of a control-mode changeover device 3, of a superconducting coil current limiter 4 and of a power changeover device 5. Then, the current limiter 4 outputs a limitation signal to the effective-power controller 1A and the reactive-power controller 2A when a current to the power changeover device 5 is limited.

Title: Device for measuring contour of surface of article supporting human body
Inventor: ROBAATO EFU WAGUNAA
IPC: A61B5/06
Filed: 1986-04-24
Abstract: An apparatus particularly suited for measuring the shape or contour of a surface under load, such as a mattress, is comprised of a humanoid having body limb extremities which are movable in a manner similar to the movement of comparable human extremities. Sensors are placed at joints, such as the knees and hips, to measure the amount of relative movement, i.e. deflection, that occurs at these joints when the humanoid is placed upon a mattress surface. The sensors provide an indication of the shape or contour of the mattress surface by correlation of the relative movement that occurs at these joints caused by the underlying mattress shape. In its preferred form, a movable frame is provided to raise and lower the humanoid in relation to the mattress surface to be tested. A "spine" is also advantageously provided with associated sensors to measure deflection, and thus surface contour, in the lower torso/abdominal region.
