Title: Toilet stool device
Inventor: YAMAZAKI HIRONORI
IPC: E03D9/00
Filed: 1998-11-19
Abstract: PROBLEM TO BE SOLVED: To easily verify health condition by discoloring the surface of a toilet stool according to urine sugar value or urine protein value when urination touches the surface of a toilet stool. SOLUTION: A surface material is used for a toilet stool 8, where the surface 9 is discolored due to uric acid value, urine protein value, the amount of blood in urine, and urine temperature when urination touches the surface 9 of the toilet stool 8. More specifically, a western toilet stool 8 is provided in a toilet room and the partial surface 9 of the toilet stool 8 has a function for reacting with constituents in urine and the urine temperature. Urine touches the surface 9 in urination, and color is develops in steps in response to the uric acid value, urine protein value, amount of blood in urine, and urine temperature. Therefore, the tendency in constituent content in urine can be easily determined without requiring any special urine-sampling device and analysis device.  Also, by flushing water onto the surface 9 in washing, the discolored surface 9 can be returned to the previous color.

Abstract: PROBLEM TO BE SOLVED: To well balancedly maintain projection resolving powers in the scanning direction and the direction orthogonally intersecting with it becomes almost equal by a method wherein the effective aperture number of a projection optical system is differentiated in the scanning direction and the direction orthogonally intersecting with it. SOLUTION: The circuit pattern on a reticle 2 is projected and exposed on a wafer 4 where the photosensitive material such as resist and the like is applied by a step and scan system through a projection lens 3. In the aligner of the step and scan system, the pattern on the reticle is not collectively illuminated, and the area of illumination is formed into a slit-like form 5. The resolution of the projection lens 3 is changed to the direction intersecting at right angle with the scanning direction by controlling the effective diameter on a pupil position 18. To be more precise, the resolution on both directions become almost equal by differentiating the number of apertures (NA) of the projection lens 3 in the scanning direction and the direction intersecting at right angle with the scanning direction.

Abstract: PURPOSE:To detect a raster edge without making arrangements even when the size of a cathode ray tube(CRT) is different by calculating the center of gravity for a peak position in the peak of data obtained by a differentiating operation by floating point arithmetic. CONSTITUTION:A raster pattern 1a generated by a signal generator 7 is displayed on the screen of a CRT 1 as a measuring object, the upper, lower, right and left sides of the raster is caught by cameras 2a-2d in order to measure the position and size of the raster pattern 1a, and this image is stored in video memories 3a-3d.

Title: Oxide-film etching method
Inventor: ZE HYON PARK
IPC: H01L21/336
Filed: 1998-12-09
Abstract: PROBLEM TO BE SOLVED: To provide an oxide-film etching method, in which the etching rate is improved and high selective etching to a lower layer film is carried out. SOLUTION: This oxide-film etching method uses a plasma etching equipment. An oxide film is etched by employing a mixed gas consisting of a first gas as a main etching gas, a second gas, for adjusting the etching direction of object which is to be adjusted, and a third gas for imparting selection-ratio characteristics to substances, excepting the oxide film 7 at etching. Since the gas, in which a gas for adjusting an angle and a gas at a high selection ratio to the substances except for the oxide film are mixed, is used besides the main etching gas at the time of etching, there has been a limit for ensuring the selection ratio to a lower layer film for the conventional etching techniques, but in this case a high selection-ratio process required from a high integrated element can be carried out.

Title: Pneumatic tire
Inventor: SHOYAMA YOSHINOBU
IPC: B60C15/04
Filed: 1997-12-04
Abstract: PROBLEM TO BE SOLVED: To improve the durability of a bead section by effectively restraining a layer line in the second layer from the outermost side. SOLUTION: When a tire runs, a bead core 12 is bent and twisted repeatedly, as a result, the layer lines 33 of the layers adjacent to each other pressingly contact each other. In this case, if the turning pitch of the layer line 33a of the outermost side layer is made larger than that of the layer line 33b to make a Young's modulus (spring constant) small, the tension torsion generated in the layer 33b becomes large, as a result, the total torsion of the compression torsion caused by bending is always in the tension side, restraining fatigue faulure.
