Abstract: PURPOSE:To handle respective machines with one operator and to improve working efficiency in saving operation for transporting work by juxtaposing a painting machine and drying machine near the taking-out port for the work of a molding machine. CONSTITUTION:An operator M puts the work taken from a work taking-out port 3 of an injection molding machine 2 in the painting booth of a painting machine 4 and places the same on a work support frame. The operator closes the door and operates a control panel and a speed controller to start driving a driving motor so that the paint is sprayed from a spray gun adjusted to an adequate position and is coated uniformly over the entire part of the rotating work. The operator takes out the work upon ending of the painting operation, puts the work in the drying booth of a drying machine 5 adjacently to the painting machine so that the work is dried by IR radiation. The dried work is taken from the drying machine and is packed successively in a product containing box 6 adjacent to the machine 5. All the operations from molding to painting, drying and boxing are thus accomplished efficiently by one operator.

Title: Method for evaluating surface layer of single crystal
Inventor: ITO NOBUO
IPC: G01N23/207
Filed: 1992-08-19
Abstract: PURPOSE:To make the intruding depth of X rays shallower and, at the same time, to change the intruding depth in the depth direction from a small area by horizontally arranging the surface layer of a single crystal and changing the illuminating angle of the X rays against the single crystal by adjusting the angle of the surface layer from the horizontal plane and angle of rotation in a plane of reflection. CONSTITUTION:A sample crystal 1 is slightly inclined by an angle alpha against the horizontal plane and the sample 1 is rotated in the horizontal direction by an angle beta under a condition where a reflecting surface is obtained. As a result, the illuminating angle thetai against the surface of the sample 1 becomes smaller. The angle thetai is expressed by sinthetai=sinalpha.sinthetaB-cosalpha.costhetaB.sinbeta, where thetaB represents the Bragg angle of the used reflecting surface. The expression shows that the angle thetai changes when the angle beta is changed and, as a result, the intruding depth of X rays changes. Therefore, the surface layer of the crystal 1 can be continuously evaluated in the depth direction by continuously changing the very shallow surface layer and angle beta. This method can be effectively used for evaluating the working distortion of a crystal or the crystallinity of a thin film formed on a substrate by epitaxial growth.

CONSTITUTION:A wire element 4 is a member composed of a conductor 2 and an insulating tape 3 covering the conductor 2. If an economical insulating tape such as a kraft paper tape or an aramid paper tape is employed as the insulating tape, naps on the surface of the tape cause insulation breakdown. In order to avoid the breakdown, a covering film 5 is applied. A polyimide film or the like which has no nap on its surface is employed as the covering tape 5. Further, a porous construction is employed to make coolant flow in and freely to cool the wire element 4 and, for that purpose, it is recommended to form a number of fine holes which are small enough not to have the naps of the insulating tape 3 penetrate in the covering film 5. As the covering film 5 is expensive, the film thickness is thin and the applied quantity of the film is very small. Moreover, a spacer 1 provided on the side surface of the wire element 4 is so constructed as to cool the side surface of the wire element with the coolant flowing in thought the fine holes of the film 5.
