Title: Pneumatic tire
Inventor: YABU MASANORI
IPC: B60C15/00
Filed: 1995-02-17
Abstract: PURPOSE: To reduce the road noise of a pneumatic tire by setting the ratio of the length of a bead part range from a rim-flange separation point to the outer end of a bead apex to the length of a tire side part range from the tire axial directional outer end point of a belt layer to the rim-flange separation point, to a specific value. CONSTITUTION: The length of a bead part range 4 from a rim-flange separation point F to the outer end T of a bead apex 9, measured along a thickness center line in the tire meridian section is defined bead part range length Hb, and the length of a tire side part range from a tire axial directional outer end point of a belt layer 7 to the rim-flange separation point F is defined L. The ratio Hb/L is set in a range from 0.30 to 0.45 or in a range from 0.55 to 0.65. As a result, a node e2 of vibration is positioned approximately in the center of tire side part rage length L, and since the outer end T of the bead apex 9 does not come closer to this position within ±5% margin, enlargement of the vibration of a peak 3 is suppressed so as to give effect on reduction of road noise.  If the ratio Hb/L is less than 0.30, the tire is deteriorated in its lateral rigidity, resulting in reduction of control stability.

Title: Sample holder for scanning type electron microscope
Inventor: KURODA KATSUHIRO
IPC: H01J37/20
Filed: 1987-03-11
Abstract: PURPOSE:To fecilitate inspection of an object with a sufficient contrast by insulating a sample from a holder as well as by grounding an electrode together with the holder while disposing the electrode in the vicinity of the surface of the sample, and by applying voltage to the sample so as to generate an electric field on the surface of the sample. CONSTITUTION:A sample 2 is mounted on a sample receiver 5 disposed through an insulation spacer 41, while an electrode 3 is mounted on a holder 1 on the front side of the sample through a thin insulation spacer 42. This electrode 3 has earth electric potential and voltage 7 is applied on the receiver 5 from the outside of vacuum. Because the spacer is thin, a strong electric field, however, can be generated with the application of a weak voltage. Also because electric field does exist in only the electrode surface of the sample 2, there is little electrostatic lens action, and therefore influence on incident electron beams is neglectable. In this manner enough electric field for elimination of patch field can be obtained, and thereby high contrast for enough inspection of an object which could not be obtained with conventional sample holders can be obtained.

Filed: 1984-03-23
Abstract: PURPOSE:To evaluate a group III-V compound semiconductor easily by forming a film corresponding to the distribution of defects through a hot water oxidation method from the compound semiconductor such as GaAs. CONSTITUTION:The surface of a substrate to be inspected consisting of GaAs is washed by trichloroethylene, etc. first, and smears are removed. When the GaAs substrate is dipped in pure water heated at 100 deg.C for approximately 3hr, a film pattern is generated on the surface of GaAs. A wafer in which etch-pits are generated is oxidized in hot water in order to prove that said pattern is in correspondence to defects of the pattern. Accordingly, the thick formation of the white film in the vicinity of a lineage line viewed as the connection of the etch- pits of black points is determined.

Abstract: PURPOSE:To obtain an orienting film which orients stably liq. crystal molecules over a long time by rubbing a specified resin film. CONSTITUTION:A soln. of photosetting cyclic polybutadiene represented by the formula is dropped on the surfaces of substrates 1, 2 and dried. Since the soln. is a negative type resist, parts of a liq. crystal cell except the display regions (the parts bounded by a sealant 5) are covered with a light shielding mask, and light is irradiated from a mercury lamp. Development is then carried out to form polybutadiene resin films, and the films are chemically stabilized by heat treatment. By rubbing the surfaces of the resin films with nylon cloth or the like, microgrooves are cut to form orienting films 4. Since the films contain cyclic polybutadiene resin as the principal component, they have superior chemical stability, are proof against about 400 deg.C high temp., and are well matched with a liq. crystal substance.
