Title: Fluorescent microscope of x-ray excitation type
Inventor: IKETAKI YOSHINORI
IPC: G01N23/223
Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To make it possible to detect a specific chemical group or element by exciting the photon energy of a specific value or lower with X rays which are made monochrome. SOLUTION: X rays which are generated by making the photon energy radiated from a synchrotron 1 monochrome at about 2000eV or lower are dispersed by a diffraction grating 2 and are condensed on the first pinhole 4 by an oblique-incidence condensing lens 3. A point image on the first pinhole 4 is reduced and formed at a point in an observed sample 6 by a fresnel zone plate 5, and an X-ray microbeam of a few dozens nanometers in size is made. Consequently, the fluorescence emitted from the observed sample 6 is condensed on the second pinhole 8 by a visible and ultraviolet light lens 7 in a visible or ultraviolet range and is gathered on a photomultiplier 9. This makes it possible to detect a specific chemical group and a trace of it and improve the contrast of an obtained image.

IPC: F16D25/0638
Filed: 1994-09-29
Abstract: PURPOSE: To increase transmitting torque and to form in small size of an automatic transmission by enlarging an area of applying pressure in a meshing structure, without increasing a thickness as a whole of a connecting shell and a reverse clutch drum. CONSTITUTION: In an edge 11C of a notched groove 11B and in an edge 12C of a notched protrusive part 12A, plastic deformation is performed at press work time, to form in thickness larger than the other part in the same members 11, 12. In the case of transmitting torque by the connecting shell 12 and reverse clutch drum 11, a pressure applied area of a collision part of the colliding edge 11C and edge 12C is increased, and the equal torque can be transmitted by a smaller applied pressure. When assumed the equal applied pressure, forming in small size and lightening weight of an automatic transmission can be performed by reducing thickness as a whole of the member and by decreasing bore size.

Title: Multilayer printed wiring board and copper foil for its internal layer electric circuit
Inventor: YOSHIDA RISABURO
IPC: H05K1/09
Filed: 1991-10-08
Abstract: PURPOSE:To produce Cu2O a lot at the time of oxidation treatment and suppress haloing development by using copper foil having specified diffracted light peak strength by an X-ray diffraction method of the Miller index surface, as copper foil for internal layer electric circuits. CONSTITUTION:An internal layer circuit board having an internal layer electric circuit made of copper foil whose surface is oxidation treated, and an external layer electric circuit laminated on the oxidation-treated surface interposing an adhesive insulating layer are provided. The peak strength of diffracted light by an X-ray diffraction method of the Miller index (200) surface of the copper foil constituting the internal layer electric circuit 1 is 41% of the peak strength of the diffraction light of (111) surface or more. This makes it possible to form an oxide film 2 having a high Cu2O ratio on the crystal face of the copper foil for internal layer electric circuits by the oxidation treatment of the copper foil, and haloing development is suppressed. Accordingly, defective adhesion of the internal layer electric circuit 1 with the adhesive insulating layer can be prevented, and the reliability can be increased since it becomes difficult for an acid treating solvent etc., to remain at the interface.
