Title: Radiographic image information reading method
Inventor: KODA KATSUHIRO
IPC: G03B42/02
Filed: 1988-04-01
Abstract: PURPOSE:To scale down a reader and to improve light condensing efficiency by condensing light emitted from an accumulating phosphor sheet on its front by means of a large optical guide and on its back by means of an optical guide physically and optically coming into contact with the sheet. CONSTITUTION:The carried accumulating phosphor sheet 3 is irradiated by excited light 1a, and stimulated phosphorescence corresponding to the information of the sheet 3 is condensed by photodetectors 5a and 5b on the front and back of the sheet 3, respectively, and is made incident on them to read information. The large optical guide 4a and the simple optical guide 4b physically and optically coming into contact with the sheet 3 condense the light to the photodetectors 5a and 5b. Since this reading method is adopted, the constitution of the radiographic image information reader can be simplified and miniaturized to improve its light condensing efficiency.

Title: Manufacture of macromolecular piezoelectric body having excellent heat resistance
Inventor: MINATO NOBUKO
IPC: H01L41/45
Filed: 1985-04-18
Abstract: PURPOSE:To improve piezoelectric property and heat resistance, by slowly cooling and crystallizing the copolymer of specified vinylidene fluoride and trifluoroethylene from a temperature higher than a melting point, then performing poling. CONSTITUTION:The copolymer of vinylidene fluoride and trifluoroethylene does not have a phase transition point Tc from a ferroelectric phase to a paraelectric phase in the region less than a melting point Tm, and the composition of the vinylidene fluoride is less than about 90mol%. Said copolymer is slowly cooled and crystallized from a temperature higher than the melting point Tm. Then poling is performed. When the poling is performed at a room temperature, it is desirable that the direction of an electric field is reversed several turns. The Tm of the copolymer is as high as about 170 deg.C. The Tc is not present in the region lower than the Tm. The heat resistance of an electromechanical coupling constant Kt in the direction of thickness is excellent. The value, which can be practically used up to a point immediately below the Tm, is maintained. Therefore, the copolymer can be used as a piezoelectric material at higher temperature than the conventional material. Thus excellent piezoelectric property and heat resistance can be obtained.

Abstract: A blank (17), which has been sheared off from a coil of wire or from a rod, is rotated through 90 DEG , this rotation being required in connection with the forging of this blank. The gripping-jaws (19, 20), serving for the purpose of transport from one station to the adjacent metal-working station, are attached, for this purpose, to rotating devices (9c, 9d), which are mounted in a manner permitting rotation and are located, on the one hand, on a guide part (7a, 7b) which is driven to reciprocate (A) and to oscillate about an axis (93), and, on the other hand, are anchored to the stationary die-holder (3) via a guiding mechanism (23a, 23b). The guiding mechanism can be regarded as a spatial double-link mechanism, possessing a connecting rod (24), a coupling link (25), a stationary pin-joint (28), a ball-joint (30), and a pin-joint (29a, 29b) which travels with the rotation device (9c, 9d). The components are arranged in such a way that the greatest part of the intended 90 DEG rotation of the blank takes place in the first half of the translational transport movement.
