Inventor: MAEDA TERUHIKO
IPC: E03F5/04
Filed: 1993-03-02
Abstract: PURPOSE:To make it possible to install a low weight and high rigidity cover in a stabilized manner by inserting the side of a stopper plate vertically installed under both ends of a rectangular-shaped steel plate main body which is slightly wider the width of a road ditch along the inner wall of the ditch. CONSTITUTION:Stopper plates 2, which are slightly narrower than the with of a main body 1 and substantially equivalent to the cross section of a ditch are installed vertically and as opposed below both ends of a main body 1 on either side fabricated with a rectangular-shaped steel plate which is slightly wider than the width of a road ditch and uneven-surfaced on the top on the opposite side. The lower ends of the stopper plates 2 are set to be slightly higher than a normal water level in the ditch. When the main body is inserted and installed continuously along the inner wall in edges 3 of both ends of the stopper plates 2, this construction makes it possible to exert resistance to curved deformation in the front and rear direction of the main body 1 and in the longitudinal direction of the ditch or either direction, thereby stabilizing the cover.

IPC: F04D29/32
Filed: 1980-05-21
Abstract: PURPOSE: To prevent a secondary flow and improve the performance thereof by a method wherein a protruded wall is provided in the path of flow in a bucket cover fixing a plurality lof moving blades.  
     CONSTITUTION: A circulating flow path is constituted with the moving blades 1, 2 and the bucket cover 3. The protruded wall 9 is provided at the flow path side of the bucket cover 3. The flow of the fluid in a high-pressure boundary layer 4b, generated at the front side surface 2b of the blade 2, flows through a boundary layer 4c and is intercepted by the protruding wall 9. Thereby, a corner eddy current generated in a low-pressure boundary layer on a back side surface 1a is prevented  and thereby preventing the reduction of the performance of the blade due to the loss of the secondary flow. According to such a method above described, the improvement of the performance may be realized.

Title: Fourier transform spectroscopy using pulse light source
Inventor: MASUTANI KOJI
IPC: G01J3/45
Filed: 1991-03-29
Abstract: PURPOSE:To facilitate spectroscopy with using a pulse light source of a longer emission period, by a method whereby frequency components in a specific range of output signals of a detector are taken out and sampled, the phase of every data is corrected and Fourier-transformed, and the spectrum of the measuring light is obtained. CONSTITUTION:An Ft-IR/spectrometer part is comprised of a synchronous pulse light source 1, an interferometer 2, a sample 3, a detector 4 and a preamplifier 5. An output of the detector 4 is, through a low pass filter 6, input to a main amplifier 7 of an FT-IR signal processing part and sampled for Fourier- transform. Supporting that the minimum of a frequency (f) of the spectrum of the measuring light modulated by the interferometer 2 is fmin, and the maximum of the frequency (f) is fmax, the light source 1 repeatedly emits light with a period 2tau satisfying (m+1)/2fmax>tau>m/2fmin wherein (m) is a positive integer. In other words, when the spectrum of the measuring light is present only in the range (m+1)/2tau>f>m/2tau, this method is applicable. Accordingly, the spectroscopy can be performed with using a pulse light source of a longer emission period.

Title: Image forming device
Inventor: HIRAO NAOTO
IPC: G03G15/20
Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To keep the quality of an image high by providing a means for preventing the irregular reflection of flash light on a toner image formed on the 2nd side of the recording medium due to the leakage of the flash light to the 2nd side of the recording medium through an area with no recording medium, at fixing the 1st side of the recording medium by the flash light emitted from a 1st fixing unit. SOLUTION: In the 1st fixing unit 7-1, the toner image transferred to the 1st side of the recording paper 11 is fixed by the flash light, in the 2nd fixing unit 7-2, the toner image transferred to the 2nd side of the recording paper 11 is fixed by the flash light. In the case of using the recording paper 11 whose width W2 is smaller than the maximum width Wmax, a pair of light shielding members 24 is installed so as to shield such an area between the 1st and 2nd fixing units 7-1 and 7-2 placed opposite to each other from light, where the recording paper 11 does not exist. The light shielding members 24 are arranged on the carrying path for the recording paper 11, and the members 24 are made movable in directions shown by arrows in accordance with the width W2 of the recording paper 11.  Thus, the occurrence of the irregular reflection due to the opposed flash lamps 71 and 72 is prevented by the light shielding members 24.

Title: Boot for shaft coupling
Inventor: MIYAMOTO KENJI
IPC: F16D3/84
Filed: 1989-03-17
Abstract: PURPOSE:To prevent the generation of the creases of a fitting ring due to the fastening of a clamp so as to prevent grease leak in a boot by interposing a sliding member between the fitting ring and the clamp in the case of assembly fitting rings formed at both ends of the boot to respective counter parts. CONSTITUTION:A sliding member 40 is formed in a layer at the bottom of the groove 31 of a fitting ring 30 to which a clamp 35 is fitted. Consequently, at the time of fastening the clamp, even if a belt-like member 37 is moved in the circumferential direction of the fitting ring 30 resistance between the fitting ring and the clamp becomes extremely small so that it becomes possible that the fitting ring 30 is fastened to an object by stronger force to improve sealability between the both. Moreover, the belt-like member 37 of the clamp moves in the circumferential direction to pull the part of the surface layer of the fitting ring so that there may be no more liability to generate creases. Also from this view point, it becomes possible to fasten the fitting rings to their counter parts with stronger force, without increase of force required to fasten the clamp.

Title: Optical waveguide
IPC: G02B6/12
Filed: 1992-03-25
Abstract: PURPOSE:To eliminate the scatter of light caused by impurities and to simplify the process by constituting the waveguide by utilizing the anisotropy of the refractive index. CONSTITUTION:Two liquid crystal parts 1 and 2 are put one over the other having their C-axial directions at right angles with each other. In this case, when light which is horizontally polarized is made incident on, for example, the upper-side liquid crystal 1 in the C-axial direction, the upper liquid crystal 1 has its main axis (C axis) in parallel to the traveling direction of the incident light and perpendicularly to an electric field direction (polarizing direction), so the refractive index nod is 1.767. For the lower liquid crystal 2, on the other hand, the incident light is considered to be an extraordinary light beam to the contrary, so the refractive index nex is 1.759 and the refractive index difference in this case is (nod-nex/nex=0.4 (%), so the waveguide has about 0.2 N. A The refractive index of a waveguide layer 1 is therefore high and the refractive index on the clad side 2 is low, so the light is confined to the waveguide layer 1.
