Title: Method for analyzing x-ray structure
Inventor: HIROZAWA ICHIRO
IPC: G01N23/20
Filed: 1991-03-04
Abstract: PURPOSE:To identify each constituent atom at the surface of a compound and to make it possible to determine the respective position by using two or more kinds of the wavelengths of the incident X rays at a sample. CONSTITUTION:The light emitted from a light source 1 for emitted light on the orbit of synchrotron is cast on a sample to be measured 4 by forming monochromatic light from the X rays with a monochrometer utilizing Bragg scattering of crystals. Here, the double- crystal type wherein the X rays whose resolution is high and which are made to be the monochromatic light are made parallel with the incident X rays is used. The incident angles of the X rays with respect to the crystal when the crystals are located at positions 2 and 3 and when the crystals are located at positions 2' and 3'. The wavelength of the X rays which are made to be the monochromatic light is changed. The wavelength of the X rays which are cast into the sample 4 is set as follows. The wavelength which is remotely separated from the absorbing end of an interested atom among the elements constituting the sample and the wavelength which is very close to the absorbing end are used. The incident angle at the surface of the sample 4 is set at the total reflecting critical angles of the respective incident angles at the surface of the sample 4. In thus way, the X rays are cast on the sample. The intensity of the diffracted X rays from the sample 4 is detected with a detector 5. Thus, the arrangement of the atoms of specified kinds on the surface or the interface is determined.

Title: Hydraulic drop hammer
Inventor: SHIMODA KATSUYOSHI
IPC: E02D7/08
Filed: 1984-02-28
Abstract: PURPOSE:To improve working efficiency, by a method wherein a weight is energized by a press force through flow-in of pressure oil to the upper chamber of a hydraulic cylinder during dropping of the weight, and after a pile is hammered through feed of a pressure to an accumulator during raising of the weight, a casing is dropped. CONSTITUTION:With a valve 22 closed and valves 23 and 24 opened through excitation of valves 25, 26, and 27, pressure oil from a pump 19 enters a lower chamber 13b of a cylinder 13 through a flow passage A, and a weight 14 is raised. Simultaneously, the pressure oil is fed to an accumulator 21 through the valve 23. When the weight 14 is raised to a switch 30, the switch is turned ON to magnetically erase the valves 25 and 27, the valve 22 is opened and the valve 24 is closed. The pressure oil enters the lower chamber 13b through the valve 23 in a flow passage C, further flows through a flow passage B to enter an upper chamber 13c, and a down force is exerted on the weight 14 which is dropped. Thereafter, although the weight 14 is brought into a raising stroke, a casing 12 is forced into a floating state, and thereby the weight 14 is prevented from raising and pushes downward the casing 12 to further penetrate a pile 15.

Title: Control method of reactive power compensating type cycloconverter
Inventor: TANAKA SHIGERU
IPC: H02M5/27
Filed: 1980-03-24
Abstract: PURPOSE:To decrease current capacity of a converter, by distributing the circulating current of cycloconverter of each phase in inverse proportion to load current. CONSTITUTION:The circulating current of a 3-phase cycloconverter is distributed on the basis of a load current IL. In the case of a U-phase converter, for example, the distribution is made on the basis of an equation : circulating current command value IOU*=(output of compensator IO*)X[(a large constant value IM)-(load current absolute value ILU)]/IM. In short, when an absolute value of load current is small, IOU* becomes large allowing much circulating current IOU to pass, and when ILU is large, IOU becomes small. By making such a motion as to obtain required reactive current on overall basis, it is possible to allow the maximum current capacity of a converter to largely decrease.

IPC: G11B11/105
Filed: 1985-02-28
Abstract: PURPOSE:To attain recording and erasure at the same time by providing a means for irradiating a recording beam and erasure beam simultaneously on adjacent tracks on a recording medium and a means for reflecting a beam directing the bias magnetic field at least in the unit of track. CONSTITUTION:Three light beams irradiated from a multi-semiconductor laser 1 are collimated by a collimator lens 2 and bent at right angles by a tracking mirror through a polarizer 4 and focuses on a face of a recording medium 8 through a half mirror 6 and an objective lens 7 as three spots.

IPC: G01B9/02
Filed: 1993-02-02
Abstract: PURPOSE:To carry out high resolution interference fringe measurement, by realizing the interfefence between basic waves and second harmonics, utilizing a feature of a nonlinear crystal. CONSTITUTION:A laser beam 1 passes through a lens 2, is incident upon a nonlinear crystal 3, collimated by a lens 4 after second harmonics are generated, propagated in the air for interferometry, etc., passes through lens 7 and is incident upon a nonlinear crystal 8 after the polarization state of reflected light from a reflecting mirror 5 is adjusted by a wavelength plate 6, etc. The second harmonics travel as they are, but a part of basic waves are converted into second harmonics and interfere with the former second harmonics. The number of this interference fringes becomes about 4X10<-6> of the number of normal interference fringes owing to a single wavelength by second harmonics, because the fringes are generated only for a portion of the difference between basic waves and second harmonics in the dispersion characteristics of air as a medium, the number of interference fringes to be measured becomes extremely few, and the very accurate phase measurement of interference fringes can be carried out.

Its output is output to the outside via a buffer amplifier 20. In a readout operation, a dummy cell is set to a state that 1 is always writen (in an erasure state). When also 1 is written to a selected memory cell (in the erasure state), the amplifiers 18-1, 18-2 or the amplifier 19 are specified so that, e.g. 0 is input from the amplifier 20. When 0 is written to a selected memory cell (in a write state), the output of the amplifier 20 is inverted, and 1 is output. In this manner, individual erasure blocks composed of many memory cells in which an erasure operation and a write operation are performed simultaneously are installed, and the erasure operation and the write operation are performed simultaneously.
