Title: Optical fiber wavelength multiplexer demultiplexer
Inventor: LAUDE JEAN-PIERRE
IPC: G02B6/34
Filed: 1998-03-30
Abstract: PROBLEM TO BE SOLVED: To improve the property and to expand each spectrum while separating the channels by making the optical index of an intermediate ring, located between a core and an optical sheath, larger than the optical index of the optical sheath. SOLUTION: An output fiber has a core and an optical sheath (cladding). The output and/or input fibers has an intermediate ring arranged between the core and the sheath and the optical index (refractive index, etc.) of the intermediate ring is larger than the optical index of the sheath. The index (n) linearly decreases from n1 at the starting point of the center 0 to a value n2 at the time of arriving at a radius a1 , it remains the fixed value n2 until reaching the radius a2 , becomes a fixed value n3 between the value a1 and the value a3 and moreover becomes a constant value n4 of the index of cladding. Such a fiber generates a fundamental transfer function. The width Δλ0 of the medium height becomes large.

Title: Grand piano
Inventor: ISHIDA MUNEO
IPC: G10C3/00
Filed: 1995-05-23
Abstract: PURPOSE: To provide a grand piano which is equal in the touch feel of the piano to the case where tones are generated by striking mechanisms and which is capable of surely prohibiting the sound production by the striking mechanisms at the time of playing by a sound source controller. CONSTITUTION: A regulating button 16 is arranged in an upward position and a jack parts from a shank roller at an ordinary timing when the other end of a turning arm of this grand piano is pulled downward. On the other hand, a regulating rail 26 is oscillated downward by its own weight and the regulating button 16 is arranged in a lower position when a wire is loosened. Since the jack parts from the shank roller at the timing earlier than the ordinary timing, a let-off section is prolonged. The action of a hammer shank 21 is, therefore, prohibited surely after the inertia action of a hammer 23 before the striking even if the accuracy at the time of positioning a hammer shank stop rail 31 to a lower side is not so high.

Title: Image processor
Inventor: TANIOKA HIROSHI
IPC: G06T1/20
Filed: 1995-05-23
Abstract: PURPOSE: To quickly obtain the picture quality equivalent to the conventional level by means of a DSP that performs the parallel processing by distributing the quantization errors to the image signals of pixels of raster following the pixel to be quantized and not to the pixels of the same raster as the pixel to be quantized. CONSTITUTION: The data input and raster image signals are switched to each other and inputted to an SVP 15 from a multiplexer MPX 9 and an MPU 16. The SVP 15 is provided with an arithmetic means which quantizes the input image signals of one raster into the quantization signals of binary levels or multilevels in parallel to each other and an output means which outputs in series the quantization signals acquired by the arithmetic means. The arithmetic means distributed the quantization errors that are caused when the input image signals are quantized to the image signals of pixels following the pixel to quantized and not to the pixels of the same raster as the pixel to be quantized. This processing result is outputted through an output terminal 6.  Thus it is possible to perform the pseudo halftone processing that involves the error correction in parallel to the image of a single raster and then to fast acquire an image of high grade at low cost.

Title: Nitriding of (alpha+beta) type titanium alloy
Inventor: MUROI KATSUMI
IPC: C23C8/24
Filed: 1979-09-28
Abstract: PURPOSE:To form a hardened layer on the surface of the (alpha+beta) type Ti alloy without lowering its strength by causing a mixed gas with N2 and Ar, etc., in a given proportion to react with the Titanium alloy for nitriding at a specific temperature. CONSTITUTION:The mixed gas containing 3-50% N2 and 50-97% Ar or He is reacted for nitriding with the (alpha+beta) type Ti alloy at 800-950 deg.C, and then the Ti alloy is quickly cooled and heat-treated at a temperature above 500 deg.C by exchanging the mixed being used with Ar or He. The reason for the use of the said diluted N2 gas is that the formation of nitrided layer is attained without and TiN compound being formed. Thus, the surface hardness of the (alpha+beta) type Ti alloy can be raised without lowering its fatigue strength.

Title: Disk cartridge
Inventor: OKADA YASUSHI
IPC: G11B19/04
Filed: 1991-04-30
Abstract: PURPOSE:To prevent a data from being changed or being collapsed by the misoperation, etc., of a user by sticking specified substance to the entire surface of an optical disk at the time of being switched to a permanent read-only condition. CONSTITUTION:When a write protecting key 7 is switched to the parmanent read-only position, an enclosing bag 8 enclosing powder state substance inside of it is exploded by the tip 7b of the key 7. Thus, the inside of a disk cartridge is filled with the powder state substance. This powder state substance generates an adhesive property by touching to the air, is stuck to the entire surface of the optical disk 1 and changed to the substance with high light permeability and high heat conductivity. When such the substance is stuck, since heat is spread to the entire surface of the disk 1 by the substance with the high heat conductivity and no heat generated by a laser beam is concentrated to a prescribed spot, no record and no erasure of a data is possible.

Filed: 1994-05-13
Abstract: PURPOSE:To enhance the signal characteristics and the heat dissipation by a method wherein a metallic layer is provided on the whole respective lead pins leaving the ends of numerous lead pins through the intermediary of an insulating layer. CONSTITUTION:Within the lead frame made of a base material comprising a metallic flat plate, etc., an island 3 in a square shape is formed in the central part moreover, multiple comblike lead pins 4, 4 are formed around the island 3.

Filed: 1992-05-18
Abstract: PURPOSE: To make a disk roll easily attachable/detachable without separating it from the driving line by providing at least two sizing rolls and two freely detachable disk rolls axially supported inside a mill stand. CONSTITUTION: At the time of exchange of a disk roll 32, the pivot frame 26 is rotated in the direction away from the pass line without separating from the drive shaft 38.

In addition, during the rotation, an angle also changes between the drive shaft 38 and the pivot frame 26. This change is tolerated by a universal coupling between the drive shaft 38 and a perpendicular driving mechanism. The disk roll 32 is removed from the arbor of the shaft for the purpose of exchanging or remounting. After the roll exchange, the pivot frame 26 is acted again.
