Title: Original exposing device
Inventor: KUDOME YUTAKA
IPC: G03B27/50
Filed: 1986-07-25
Abstract: PURPOSE:To obtain high resolution, and also, to uniformly distribute the quantity of incident light to a photosensitive body by reducing a temperature rise, by using a light source for increasing the light quantity for exposing both end sides in comparison with the center part in the width direction vertical to the scanning direction, and also, using a slit for enlarging the slit width of both end sides in comparison with the center part in the width direction. CONSTITUTION:A light source for increasing the light quantity for exposing both end sides in comparison with the center part in the width direction vertical to the scanning direction is used as a light source, and a slit for enlarging the slit width of both end sides in comparison with the center part in the width direction is used as a slit. For instance, a light source of an emitted light quantity distribution as shown by a full line in the figure is used as a light source 3, and as for a slit 5, the slit width is enlarged in a ratio of k/2 to both sides of w1 up to width of L2 corresponding to an effective width of a photosensitive body 11, so that the slit width is constant w1 from the center of the slit to the width of L1, and the slit width (w) in a position of L of its outer side is w=w1+k(L-L1).

Title: Frequency multiplier
Inventor: FUJINO TADASHI
IPC: H04L27/227
Filed: 1981-10-29
Abstract: PURPOSE:To reduce jitters of a reproduced carrier wave, by setting a multiplier at the input side of a nonlinear element in order to multiply an input m-phase PSK wave by a rectified cosine waveform using the symbol time of said PSK wave as its half period, and then to have m-multiplication by the nonlinear element. CONSTITUTION:The phase transition of m-phase shift keying PSK of a multiplier 6 is shown by the vector of a product of 4-phase PSK wave and a shaped waveform (dospit/T)<m> in the case of m=4. When an input PSK wave 1' changes to 1 from 0, the output of the multiplier 6 does not shift directly to 1 from 0 but shifts to 1 after once shifting to the original point from 0. Therefore the phase jitters are not virtually included to a reproduced carrier wave 2' of m- multiplication for the output of a nonlinear element 3'. Thus the self-noise produced here are substantially equal to AM noises and can be eliminated by setting an amplitude limiter at the output side of the wave 2'.

Abstract: PURPOSE:To reduce coupling loss due to the lowering of a ratio resistance value, by arranging wire materials which become diffusion sources, within a copper alloy matrix, and compensating the reduction of a matrix addition element quantity at the time of heat treatment for Nb3Sn generation. CONSTITUTION:At a complex wire 10, an Sn wire 12 is arranged at the center portion of the inside of a Cu-10wt.%Ni alloy matrix 11, and Nb pipes 14 which house Cu covered Sn wires 13 insides, are arranged on its outside. A superconducting wire matrix ratio resistance value, with the wire 10 administered with the heat treatment of 30 hours under 600 deg.C degrees, is at 2T, 1.7X10(-7)OMEGAcm. At a superconducting wire 15, a plurality of remaining Nb pipes 17 are arranged within a Cu-Ni-Sn alloy matrix 16, and an Nb3Sn layer 18 is formed on the inside of a pipe 17. In addition, marks 19 denote Cu-Sn alloys. Meanwhile, the matrix ratio resistance value of a superconducting wire made similarly by using the same shape Cu-10wt.%Ni alloy wire instead of a Cu-Ni covered Sn wire, is at 2T, 0.7X10(-7)OMEGAcm. As a result, the lowering of a ratio resistance value is prevented, and the reduction effect of coupling loss between filaments can be maintained.

Filed: 1979-12-29
Abstract: PURPOSE:To reduce the temperature rise of two primary windings connected in parallel in an oscillation transformer by connecting a diode to the primary winding of the transformer and thereby suppressing the occurrence of a loop current due to irregularity of the transformer. CONSTITUTION:Diodes D1, D2 are connected between the common connecting points P, P' of the primary winding of the oscillation transformer in which two primary windings A, B are connected in parallel with one another, the points P, P' are connected in reverse polarity and connected through a coke coil L1 to a power source DB. The collectors of push-pull transistors Tr1, Tr2 are connected to both ends of the primary windings A, B. Independent discharge lamps FL1, FL2 are connected to the secondary windings A', B' of the oscillation transformer OT, and  are thus energized. Accordingly, a loop current flowing between the windings N1  and N1' due to the irregularity of the transformer OT can be eliminated by the  diodes D1, D2, and the temperature rise of the windings can be thus reduced.

IPC: E04F13/08
Filed: 1995-07-11
Abstract: PROBLEM TO BE SOLVED: To prevent sinking of the head of a nail into a siding material and to prevent the deformation of the siding material to be caused by variations in temperature by forming projected threads slightly higher than the height of the head of the nail around a nailing slot formed in the siding material for covering an exterior wall of a building. SOLUTION: Projected threads 15 are so formed aroung a nailing slot 14 formed in a siding material 10 that the nailing slot 14 is held between the projected threads. The height of each of the projected threads 15 is slightly higher than the height (h) of the head of a nail 17 to be used. Accordingly, since the nail 17 is mounted in a floating state with space open without sinking of the head into the nailing slot 14, the siding material 10 is freely expanded along the nailing slot 14 with the temperature variation. By the constitution, the deformation of the siding material can be prevented.

Abstract: PURPOSE:To obtain a hologram having required condensing and polarizing functions without the generation of aberration by irradiating at least one optical wave out of optical waves formed by the hologram to a recording medium through deflecting elements and irradiating the reproduced optical wave to an interference pattern through the deflecting element. CONSTITUTION:Coherent spherical wave beams with wavelengths lambda2 to be converged upon respective points Q1, Q2 are irradiated to the recording medium through optical deflecting elements (prisms) 3, 4 and an interference fringe pattern is recorded to form a hologram 1. At the time of reproducing, a laser diode 2 with wavelength lambda2 (lambda1>lambda2) is arranged on a position P1 separated from the hologram 1 by f1 to irradiate the hologram 1 through an optical deflecting element [a thick glass plate with thickness (d)] 5. Consequently, a reproduced hologram optical wave converged upon the point P2 is obtained. Since the hologram recording medium is irradiated through the deflecting elements 3-5 at the formation of the hologram and at its reproduction, aberration due to the difference of wavelength values between the formation and reproduction is corrected and highly accurate correction for aberration can be attained.
