IPC: C22F1/00
Filed: 1987-01-27
Abstract: PURPOSE:To improve strength and ductility independently of plate thickness, by strictly controlling the conditions in solution heat treatment stages in heat treatments after cold working and final cold working stages to specific conditions, respectively. CONSTITUTION:Cold working in a former stage of the final cold working is applied to a beta-type Ti-alloy material at >=30% draft. Subsequently, intermediate solution heat treatment is finished by subjecting the above material to temp. rise up to a beta-temp. region at >=2 deg.C/sec temp.-rise rate to complete recrystallization and then to cooling down to <=300 deg.C at >=2 deg.C/sec cooling rate. Further, the final cold working is applied at 3-<30% draft and, in the successive final solution heat treatment, the above material is subjected to temp. rise up to the beta-temp. region at >=2 deg.C/sec temp.-rise rate and then to cooling down to <=300 deg.C at >=2 deg.C/sec cooling rate. By strictly controlling, as mentioned above, the temp.-rise rate and cooling rate at the time of solution heat treatments is particular, a beta-type Ti-alloy material excellent in strength and ductility even if plate thickness is increased can be obtained.

Title: Resistance heating boat for vapor deposition
Inventor: NAKAO MASABUMI
IPC: C23C14/26
Filed: 1987-01-27
Abstract: PURPOSE:To prevent direct arrival of bumping particles of a material for vapor deposition at a surface for vapor deposition by forming perforated cylindrical resistance heating element of a chimney type heating boat into double cylinders, covering the specific part thereof with heat resistant fibers and heating the innermost resistance heating elements to the max. temp. CONSTITUTION:The perforated cylindrical resistance heating elements 2, 2' are concentrically disposed in parallel in a cylindrical vessel 1. The inside of the heating element 2 and the outside of 2' are melted by heating and are covered with meshes 8 made of the heat resistant fibers. The material for vapor deposition is housed into a housing part 3 in the spacing between the inside wall of the vessel 1 and the heating element 2 and a voltage is impressed between the vessel 1 and the heating elements 2, 2' via conductors 4, 5. The heating elements 2, 2' and the meshed 8 are thereby made to generate heat quickly and the material for vapor deposition is heated to evaporate. The vapor thereof passes the through-holes of the elements 2, 2' and the meshes 8 and is released through the aperture 7 of a cap 6 to the outside. Splashing of the bumping particles of the material for vapor deposition is substantially prevented by the meshes 8 even if said material bumps and the bumping particles thereof partly pass the through-holes of the element 2. The particles collide against the meshes 8 of the element 2' even if said particles splash. The probability that the particles are released directly from the aperture 7 is therefore smaller.

Title: Shutter type bathtub lid
Inventor: UEDA SHUNJI
IPC: A47K3/00
Filed: 1994-02-09
Abstract: PURPOSE:To provide a shutter type bathtub lid which facilitates handling with a lighter weight and minimizes the generation of mildew with higher endurance. CONSTITUTION:In a rollable shutter type bathtub lid 1 in which a number of hard strip-shaped hollow members 2 are linked side by side with soft strip- shaped link members 3 in a size enough to cover the top surface of the bathtub, the hollow members 2 comprises a polypropylene resin and the link members 3a thermoplastic elastomer. As the specific weight of the polypropylene resin is very small, the product is by far lighter as compared with the conventional type made of a polyvinyl-chloride resin. In addition, no much of a plasticizer or the like is contained in the soft thermoplastic elastomer link members to eliminate the generation of deterioration and cracking due to prolonged use and the lowering of a slippage resistance value thereby enabling the prevention of mildew.

Title: Inspection for defect of reticle
Inventor: KATOU TAKAAKI
IPC: G03F1/84
Filed: 1981-02-03
Abstract: PURPOSE:To obtain the accurate inspection result by a method wherein the standard pattern data for a reticle are divided into fine meshes and the ratio of a part composing the pattern and a part not composing the pattern of each mesh are calculated and memorized and a reticle sample is scanned by the light so as to be compared with the memorized information, so that the defect is inspected. CONSTITUTION:The standard pattern data are divided into fine meshes on a chip 12 including the pattern 13 and the ratio m of a part 15 composing the pattern and a part 16 not composing the pattern of each mesh is calculated and memorized by a computer. Then a reticle is provided as a sample and the sample is scanned by the light. The intensity of the transmitted light detected by a light detector fluctuates in accordance with the existence or non-existence of the pattern. This fluctuation is converted into the electric signal information by an photoelectric element and this converted pattern information is compared with the standard design data of the reticle pattern previously memorized by the computer, so that the defect contained in the reticle pattern is detected.

Title: Image processer and its method
Inventor: TODA YUKARI
IPC: H04N1/387
Filed: 1998-01-28
Abstract: PROBLEM TO BE SOLVED: To provide the image processer by discriminating a direction and a composition direction, even from image signals that are not well binary- processed so as to optimize the direction of a double-sided copy, a document with a reduced layout, and a file margin position. SOLUTION: An image signal received via an input section 301 is once stored in a page memory 312. An isolated point elimination section 313 eliminates isolated points of the received image signal and the image signal, whose isolated points are eliminated, is outputted to a direction discrimination section 314. The direction discrimination section 314 discriminates the direction and a composition direction (vertical writing, lateral writing) of the received image signal and gives the result to a page memory control section 310. The page memory control section 310 selects image information to be outputted and reads it, while selecting a read address of the page memory 312 so as to obtain a proper layout in accordance with the direction discrimination result.

Title: Electrophoresis apparatus
Inventor: MIYAMOTO HITOSHI
IPC: B01D57/02
Filed: 1989-01-27
Abstract: PURPOSE:To maintain the performance of an apparatus, to reduce the using amount of liquid and to use the apparatus for a long period without replacing the liquid by providing a means which applies voltages having the different polarities across first and second electrodes for every specified period. CONSTITUTION:A first electrode is made positive, and a second electrode is made negative. A voltage is applied for a specified period. Then liquid in each block is ionized. Cations migrate to the second electrode. Anions migrate to the first electrode. Therefore, the cations of the liquid in the block on the first electrode side pass through a cation transmitting electrode film and enter into the block between the electrode films. Similarly, the anions of the liquid in the block on the second electrode enter into the block between the electrode films. Meanwhile, the anions and the cations in the block between the electrode films cannot pass through the electrode film. Therefore, the concentration of the liquid in the blocks of both electrodes is decreased. When the polarities of both electrodes are changed before the decrease in concentration reaches a limit, the cations and the anions migrate to the reverse direction with respect to said direction, and the concentration of the liquid is recovered. This procedure is repeated, and the excellent performance of the apparatus can be maintained without replacing the liquid for a long period.
