Title: Y branched optical waveguide
Inventor: INOUE NAOHISA
IPC: G02F7/00
Filed: 1985-09-13
Abstract: PURPOSE:To expand the branch angle with the comparatively low loss by providing the low refractive index part at the terminal of the first three-dimensional optical waveguide and forming the second and third three-dimensional optical waveguides branched at the Y character shape at the substrate in succession to the low refractive index part. CONSTITUTION:Since the closing effect of the light to the side is not made at a low refractive index part 4, the light to propagate the first three- dimensional optical waveguide 1 is widened by an angle l/D in the same way as the coming-out light from the aperture when the light comes to a terminal line A. Here, l is the wavelength of the light and D is an optical waveguide width. The light proceeds while the light expands the low refractive factor part, and since the high refractive factor part due to the second and third optical waveguides 2 and 3 is present, the power of the light is collected to a line B. The light is more widened and has two peaks. The field distribution is overlapped with the field distribution of the mode in the optical waveguides 2 and 3, and the light power is separated to the second and third optical waveguides 2 and 3. Thus, the low loss and the large branch angle can be improved.

Title: Treatment method for material accountancy of radioactive material
Inventor: OKUNO KENJI
IPC: G21B1/00
Filed: 1996-07-31
Abstract: PROBLEM TO BE SOLVED: To accurately calculate tritium amount captured in whole surface area by casting ultraviolet laser, giving material surface abrasion and uniformly vaporizing or gasifying only within the irradiation area with photochemical effects. SOLUTION: Ultraviolet laser transmitted through a fiber 24 is focused with a lens 26 and casted on a specific area surface of a material 20. On the surface of the material 20 irradiated by the ultraviolet laser, abrasion is caused and the surface is ground according to the energy density and shot number. Tritium dissociated from the surface by the abrasion is extracted out through an exhaust pipe 28. By measuring the tritium amount in the exhaust air with a quadrupole mass analyzer 30 connected with the exhaust pipe 28, the tritium in the area of abrasion can be measured. By examining the measured tritium amount as a function of depth, the captured tritium amount as a function of the depth in the surface layer of the material 20 can be measured.

IPC: G01R31/00
Filed: 1987-08-13
Abstract: PURPOSE:To efficiently perform highly reliable measurement, by mounting an IC device to an IC socket and obtaining electrical connection with respect to a measuring electrode. CONSTITUTION:An IC device to be measured falls on an IC guide rail 1 under its own wt. to be supplied. A feed means 2 sucks and secures the supplied IC device from the surface thereof to mount the same on each of the IC socket 4 mounted to the IC block board 3 provided under said feed means 2. The board 3 consists of one common substrate and individual substrates each having the socket 4 mounted thereon. That is, the sockets corresponding to the IC devices to be measured are fixedly mounted on the surfaces of the individual substrates. Therefore, a through-hole having pin of the socket inserted therein to be soldered thereto and the wiring pattern electrically connected to said through-hole are formed to each of the individual substrates.

Title: Optical transmission line
Inventor: KOBATA NOBUO
IPC: H04B10/25
Filed: 1993-08-16
Abstract: PURPOSE:To perform efficient branching and coupling between a bus fiber and tap fibers in the transmission line where plural optical couplers are coupled and to obtain equal output levels by setting parameters of optical fibers so that they are successively different by continuous optical couplers. CONSTITUTION:Two optical, fibers 211 to 213 and 211 to 213 different by parameters are connected in a welded part with respect to at least one optical fiber of each optical coupler, and the parameter 221 to 223 of one optical fiber out of two optical fibers different by parameters is different in each of continuous optical couplers. A proportion of coupling to the output tap is small in a first optical coupler 31 because the optical mower from a bus fiber 10 is higheset but the clad of the tap fiber 221 is thick. Meanwile, proportions of coupling are increased in succeeding optical couplers 32 and 33 because clads are made successively thin, and the optical power is efficiently obtained, and approximately equal outputs are obtained.

Filed: 1993-07-26
Abstract: PURPOSE:To obtain recording paper having no defect of letters and picture images slightly being watched in a specific direction, showing a white ground by constituting the recording paper in such a way that indecent light will not propagate in the direction parallel to a paper plane in the paper and reflected light goes out in a scattering manner. CONSTITUTION:A reflecting layer 3 comprising a metal foil, e.g. aluminum foil or a multi-layer film of a dielectric material such as zinc sulfide, having 50-1,000mum thickness is formed on paper 4 comprising fibers of trees and plants. Further spherical transparent balls 2 having excellent light transmission and 2-20mum diameter are uniformly dispersed and fixed through an adhesive to the reflecting layer and a transparent film 1 such as polyethylene having excellent light transmittance and ink absorption is laminated to the reflecting layer to give recording paper. Since light going from the surface of the recording paper is transmitted through the transparent film 1, part of the light is reflected in a scattering manner from the surface of the transparent balls 2, the rest of the light is not scattered in the direction parallel to the paper plane, reflected through the interior of the transparent balls 2 from the reflecting layer 3 and diffusively goes out in a scattering manner from the paper plane in the wide direction, the distance between indecent light position of light and going out position of the light is small and light spreading and dot gain phenomena are suppressed.

IPC: G11B15/467
Filed: 1994-08-26
Abstract: PURPOSE:To produce a magnetic tape scanning device executing appropriately variable-speed reproducing and variable speed recording without complicating a drum structure. CONSTITUTION:A lead angle of a head when a magnetic tape is in a still state is theta1 and smaller than a cojnventional lead angle. Therefore, when a double speed reproducing and recording is executed, a rotational speed of an upper drum becomes 30 rps which is half of conventional 60rps. And, adjacent trucks are scanned simultaneously by two heads and whole trucks are scanned appropriately. The lead angle is changed to halve the rotational speed of the head like this, a handled frequency becomes a half, a circuit production is simplified, and a high speed double speed reproducing and recording which can not been attained on the point of a conventional circuit characteristic are capable.

Title: Electronic still camera
Inventor: TANAKA YOSHITO
IPC: G03B13/36
Filed: 1989-08-03
Abstract: PURPOSE:To reduce the load of a power supply and to give no influence to the operations of a video circuit and a recording system as well as the operation of an auto-focus mechanism by controlling the drive of the auto-focus mechanism and the drive of the recording system of a spindle motor, etc., in the prescribed sequence. CONSTITUTION:When a focusing action is through with use of an auto-focus mechanism, either one or both of the power supplies of a recording medium drive mechanism and a video process circuit are turned on. Therefore the power supply of the drive mechanism of a recording medium like a floppy disk, etc., and the power supply of the video process circuit are turned on when a focus control action is over with use of the auto-focus mechanism. Thus both the auto-focus mechanism and the drive mechanism of the recording medium are never driven at one time. Then the power voltage produce no large fluctuation.
