IPC: G01T1/161
Filed: 1992-09-30
Abstract: PURPOSE:To obtain a good image by automatically correcting body movement by performing correction so as to cancel the movement in linear and rotary directions of an examinee calculated from the displacement of the centers of gravity of two or more concerned areas set on an image. CONSTITUTION:The data stored in a memory 7 are read at every fixed time during the sampling of data to reconstitute an image by a computer 8 and the centers of gravity of two or more concerned areas are automatically calculated from the obtained image and the positional fluctuations of the centers of gravity are grasped by the comparison between successively obtained images. The movement and rotation of an examinee 1 are detected on the basis of the movement of the centers of gravity and the reconstituted image is moved in the opposite direction by the moving quantities (distances) in the X- and Y-directions of the centers of gravity by sending a command from the computer 8 to the memory 7 to negate the movement of the examinee 1 and, when the centers of gravity are rotated by an angle theta, the centers of gravity are rotated by the angle theta in the opposite direction to offset rotation. By this constitution, body movement can be automatically corrected on the image without imparting pain to a patient or applying labor to an operator.

Abstract: PURPOSE:To obtain a high quality multi-color image even on a medium to be transferred having a low surface smoothness by providing a light source at a supporting material side, a heat source at a transfer recording layer side and a transfer means along a carriable path of a transfer recording medium. CONSTITUTION:A multi-color transfer recording medium 1 is composed of a light transmission base film 1b which is provided with a transfer recording layer 1a.

Title: Nondestructive method for estimation of toughness
Inventor: NAKAI NORIHIKO
IPC: G01N33/20
Filed: 1991-06-22
Abstract: PURPOSE:To evaluate toughness accurately in a nondestructive manner by using a quenching speed, temper hardness and quenching temperature as parameters and by using a function of the amounts of these parameters. CONSTITUTION:A quenching speed (CR), temper hardness (H) and quenching temperature (T) are used as parameters, and the toughness (Ch) of a material is estimated as a function [Ch=f(CR, H, T)] of the amounts of these parameters. As for the material to be applied, SKD5, SKD6, SKD61, SKD62, SKD7, SKD8, etc., are mentioned and the material of which the state of the heat-treated texture is affected by the quenching speed is an object. The quenching temperature (T) is measured by measuring an inner-furnace atmosphere temperature by a thermo-couple, for instance, for the purpose of evaluating the austenitized state of the material. By measuring the hardness, the quenching temperature and the quenching speed with the relationship of the amounts (Ch, H, T, CR) determined beforehand, the toughness can be estimated in a nondestructive manner.

Title: Molding die and manufacture of optical element
Inventor: YAMAZAKI MASAAKI
IPC: B29L11/00
Filed: 1998-09-25
Abstract: PROBLEM TO BE SOLVED: To provide a molding die which does not form wrinkles even when a mumber of dents are formed. SOLUTION: Since this molding die comprises a die base metal 4 having a mumber of pores and an electroless nickel plating layer 5 coating the surface to be molded, when a dent for element 3b is to be formed, the electroless nickel plating layer 5 is deformed in accordance with the surface shape of an indenter on a cavity surface 3a, and the die base metal 4 is also recessed while reducing the volume of the pores in accordance with the surface shape of the indenter. In other words, since the volume change due to the deformation in a process of dents is absorbed in the pores of the die base metal 4, wrinkles are hardly formed around the dents for element 3b, so that the wrinkles can be prevented from being formed on the surface of an array of microoptical element to be molded by the resultant molding die.

CONSTITUTION:A coil 2 is formed by winding a conducting wire around the lower outer circumference of the cylindrical bobbin 1 for the coil made of kraft paper, a resin film or metallic foil, end after the coil lead wirses 3 st both ends of the conducting wire are wound around the external lead wires 4 made of copper foil string, etc., they are connected by soldering, etc., and further, the connection part is coated with nearly 100% solid content monoliquid humidity setting type hot melt adhesive 6 (trade name: Highbon 4830 manufactured by Hitachi chemical polymer Co.) heated at about 120 deg.C, and is firmly bonded. Thus, time can be greatly shortened compared with bonding by the volatilization of solvent. Besides, contraction at the time of bonding is small because of 100% solid content, and the deformation of the bobbin for the coil due to contraction force is never caused.
