Title: Optical demultiplexing device and optical demultiplexing and multiplexing device
Inventor: INAGAKI SHINYA
IPC: H04B10/29
Filed: 1999-09-01
Abstract: PROBLEM TO BE SOLVED: To demultiplex one light signal having arbitrary wavelength by making good use of 4-light-wave mixture carried out in an optical fiber. SOLUTION: In the optical demultiplexing device 1, a 1st WDM(wavelength- division multiplex) light signal generated by multiplexing multiple light signals of different wavelengths is made incident on a generating means 11. The generating means 11 generates a 2nd WDM light signal by 4-light-wave mixture with the 1st WDM light signal and incident exciting light. The 1st and 2nd WDM light signals are made incident on a demultiplexing means 12 provided in the stage following the generating means 11. The demultiplexing means 12 extracts light of specific wavelength. Then a control means 13 controls the wavelength of the mentioned exciting light. Consequently, the channel of the WDM light signal demultiplexed by the demultiplexing means 12 is changed by varying the wavelength of the exciting light, so an arbitrary channel can be demultiplexed.

Filed: 1987-10-02
Abstract: PURPOSE:To enable controlling backward gate leak current, by forming a different kind of metal whose chemical bonding energy to InP is large, between a metal constituting Schottky gate and InP. CONSTITUTION:An N-type InP (100) substrate 1 is irradiated with P molecular beam, and heated in an ultra-high vacuum to obtain a clean surface. Then, by molecular beam epitaxial growth method, an Sb layer 2 of 1/10 atom layer is deposited on the surface at a room temperature. Thereon an Au layer 3 of 500Angstrom  is deposited to form a gate electrode, and Ni/AuGe ohmic contact is formed for a source 4 and a drain 5. Since a different kind of metals having large chemical bonding energy to InP is formed in thickness of 1/10-30 atom layer between the metal and InP, the height of Schottky barrier is increased, and backward leak current is restrained.

Title: Spacial-section treating structure between membrane materialand wall body in membrane structure
Inventor: KURISUTOFUAA HITSUCHIKOTSUKU
IPC: E04H15/32
Filed: 1993-10-04
Abstract: PURPOSE: To improve appearance, durability and the like by disposing a tubular expansion- contraction body being expanded and contracted by the supply of air to a space section between a stretched membrane material and a wall body for closing the space section. CONSTITUTION: Since an expansion-contraction body 4 is supplied with air at all times and expanded, and a space section 3 is closed, appearance is improved by the expansion-contraction body expanded in an approximately cylindrical shape in the space section 3. When external force is applied to a membrane material 1, the expansion-contraction body 4 is deformed freely and absorbs external force while being restored when external force is remove. Since crease does not remain in the membrane 1 and the expansion-contraction body 4 at that time, an excellent appearance is maintained.  When large external force or the like is applied to the expansion-contraction body 4 and the internal pressure of the expansion-contraction body 4 reaches a fixed value or more, a safety valve installed to the expansion-contraction body 4 is opened and partial air is discharged to the outside, and the damage of the expansion- contraction body 4 is prevented. The expansion-contraction body 4 prevents the infiltration of rainwater or the like to the inside from the membrane material 1. Accordingly, appearance can be improved, the damage is prevented and the body 4 can be used for a prolonged term, and besides the body 4 can be executed safely and easily.

IPC: B42D15/10
Filed: 1996-09-19
Abstract: PROBLEM TO BE SOLVED: To improve forgery preventing ability by sealing a tally impression over two edges of a hologram and a base material to which the hologram is stuck. SOLUTION: A tally impression 3 sealed over two edges of a hologram 1 and a base material 2 may be sealed with pressure by an ordinary seal having a print of seal by using a cinnabar seal-ink, or may be sealed with heat by a heat resisting seal having a print of seal. By forming a tally impression 3 by pressing or heating the seal, the print of seal part of the hologram 1 having the tally impression deforms or discolors. Accordingly, when peeling of the hologram 1 from the base material 2 is attempted for copying it, an original can not be copied because the tally impression 3 is already sealed on the hologram 1. Even when the original is copied, it can be easily determined to be a forged copy.

Title: Paper feeding device and image forming device provided with the paper feeding device
Inventor: SAKAMOTO TAKAHIRO
IPC: B65H3/06
Filed: 1998-09-02
Abstract: PROBLEM TO BE SOLVED: To prevent a defective separation, defective paper feeding and skew of a sheet by providing a first regulating member regulating bending of a paper feeding roller shaft in the direction opposite to a sheet mounting base and a second regulating member regulating bending of the paper feeding roller shaft in the direction opposite to the sheet feeding direction. SOLUTION: A paper feeding roller shaft 4 receives paper feeding pressure of a cassette spring 8 and is going to bend in the direction opposite to a sheet cassette 1. But, because a rib 20 on the paper feeding roller shaft 4 is in contact with/regulated on a first regulating part 12, the paper feeding roller shaft 4 does not generate bending in the direction receiving paper feeding pressure. Therefore, the paper feeding roller shaft 4 is capable of always performing a paper feeding operation, keeping straightness. Paper feeding rollers 2, 3 receive carrier force generated due to abutting of the rollers 2, 3 on a sheet P, the paper feeding roller shaft 4 receives reaction force in the direction opposite to a sheet feeding direction and bends in the direction.  When the paper feeding roller shaft 4 generates bending of ΔX, the rib 20 on the paper feeding roller shaft 4 comes into contact with a second regulating part 13 and does not generate bending of ΔX or more.

Title: Flaw detecting apparatus
Inventor: WATANABE KAZUO
IPC: G01N21/88
Filed: 1988-09-29
Abstract: PURPOSE:To detect a flaw with stable sensitivity irrespective of the size thereof by illuminating a sample slantwise and operating image data of said sample picked up by the scattering light and image data obtained at a plurality of positions when said sample is moving. CONSTITUTION:A light radiated from a lamp 2 is condensed by a reflecting mirror 1, passed through a filter 3 and radiated to the surface of a test board 4. Accordingly, the radiated light becomes so strong as not to expose the test board. At the same time, since the radiating angle is inclined, the reflected light is prevented from entering a camera 6. If the surface of the test board 4 is flawed or attached with a foreign article, the light is scattered at that portion and a part of the scattering light enters the camera 6 through a lens 5 thereby to form an image. When this image is processed by an image processor 7, the flaw is judged whether it is large or small with stable sensitivity. The camera 6 is able to pick up images by a long time exposure by cooling a CCD pickup device by an electronic cooling device.
