Title: Piezoelectric-element driving method in minute hardness meter
Inventor: FUKUYAMA HIRONARI
IPC: H01L41/09
Filed: 1990-08-30
Abstract: PURPOSE:To decrease hysteresis and to obtain a highly accurate target pushing depth by connecting a capacitor to a piezoelectric element in series, and applying pulses from zero volt to the maximum applied voltage. CONSTITUTION:A capacitor 2 is connected to a piezoelectric element 1 in series. A high-voltage amplifier 3, a D/A converter 4 and a computer 5 are connected to the capacitor 2. At a position where an indenter 7 is separated from a sample 8 with an X-Z stage 6, a pulse-shaped voltage is applied on the piezoelectric element 1. Thus, the piezoelectric element is polarized, and the remaining displacement becomes the initial position. Then, the indenter is brought close to the surface of the sample with the X-Z stage 6, and a voltage corresponding to the indenter pushing depth is applied. Thus, the piezoelectric element is displaced, and the indenter is pushed into the sample. The hardness of the sample can be measured based on the relationship between the pushing depth and the load indicated by an electronic balance at this time. When the capacitor is connected to the element in this way, the hysteresis and the creep of the piezoelectric element can be decreased.

Title: 90× twisted waveguide with step
Inventor: ENDO NOBUHIRO
IPC: H01P1/02
Filed: 1992-08-05
Abstract: PURPOSE:To reduce the manufacture man-hours and to decrease the production cost while keeping the electric performance by forming an inner wall corner of a hollow part to be a circular-arc shape. CONSTITUTION:Rectangular waveguides 2, 3 have respectively rectangular hollow parts 2a, 3a whose inner wall corner is formed to be circular-arc. Then the rectangular waveguide 2 is arranged so that its rectangular hollow part 2a is tilted by 26.4 deg. with respect to the rectangular waveguide 1 and the rectangular waveguide 3 is arranged so that its rectangular hollow part 3a is tilted by 63.6 deg. with respect to the rectangular waveguide 1. Thus, the rectangular follower parts 2a, 3a are formed by cutting by a milling machine or the like by forming the inner wall corner of the rectangular hollows 2a, 3a to be a proper circular-arc. That is, the discharge processing process is omitted in the manufacture of the rectangular waveguides 2, 3 and the manufacture man- hours are reduced. Furthermore, since the rectangular waveguides 2, 3 are manufactured by the cutting only without use of the electric discharge machining, the production cost is reduced.

Title: Method for growing single crystal of silicate of rare earth element
Inventor: KURATA YASUSHI
IPC: C30B29/34
Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To stably obtain a single crystal free from voids and having satisfactory performance as a scintillator by specifying the concn. of Al as an impurity in a stock melt contg. oxide of a rare earth element and silicon oxide. SOLUTION: Characteristics of a grown single crystal are affected by a specified impurity element in stock. In the case of growth of a gadolinium silicate single crystal, gadolinium oxide having a low concn. of Al as an impurity is used as stock. By this low concn. of Al, the occurrence of voids in the resultant crystal is prevented and characteristics as a scintillator can be improved. Since the crystal is free from voids, fluorescence generated in the crystal by irradiation efficiently reaches a photomultiplier brought into contact with one face of the crystal and the fluorescence output and energy resolving power of the photomultiplier are enhanced. As a result, characteristics of the crystal as a scintillator are improved. When stock having <=0.4ppm concn. of Al as an impurity is used, oxide of a rare earth element having <=0.4ppm concn. of Al is preferably used.
