Title: Semiconductor inspecting method
Inventor: SEKIGUCHI TOMOKO
IPC: G01N23/20
Filed: 1998-04-06
Abstract: PROBLEM TO BE SOLVED: To rapidly detect the generation of failures and to improve the yield by performing the X-ray diffraction measurement of an end part on a wafer, where Al is formed from two different directions and estimating the generation of electromigration according to the difference in the intensities. SOLUTION: Incidence X rays A12 are applied from a direction that is vertical to a direction which is directed from a central pat to an end part onto a measurement region 2 that is away from the center of a wafer to the end part, for example, by at least 50% of the radius of the wafer on a wafer 1 where Al or Al alloy is formed, and diffraction X-rays A22 on an Al (111) surface are detected by an X-ray detector A21. The diffracted X-rays measure a range of ±5 deg.C with an angle obtained from the Al (111) surface as a center, and the Al (111) diffraction intensity in a direction, that is in parallel with a direction being directed from the center being stored in an arithmetic processing unit toward an end part is divided by the Al (111) diffraction intensity in a vertical direction.  When the value is not within 0.8-1.25 range, it is decided that the wafer 1 to be inspected may possibly result in an Al electromigration failure and hence is eliminated from the line.

Title: Tester for piston ring
Inventor: TATEISHI YUKIO
IPC: G01M15/00
Filed: 1987-04-17
Abstract: PURPOSE:To enable the checking of the property of following a piston accurately during the oscillation of a piston, by arranging a device to reproduce behavior after the model of an elastic deformation of a piston skirt section due to a piston slap. CONSTITUTION:A cylinder 12 is fixed on a frame 10 and a piston 14 with a piston ring for test mounted thereof is fitted thereinto the measure the angle thetaof a connecting rod 18 so that an angle of crank maximizes a side pressure previously calculated. The axis center of a piston pin 16 is offset from the axis center of the cylinder 12 to make the piston 14 inscribe the cylinder 12. Then, a vibration load generator 30 applies a load equivalent to a difference between a gas pressure working on a piston head previously calculated and an inertial force working on a piston 16 at a position on a cylinder axis center of the piston 14 with the frequency corresponding to revolutions of an engine through a link ball bearing 24. This causes the piston 14 to perform the same oscillation as that of a piston slap. The state of detection of sensors 41 and 42 or the like are observed and recorded to make clear the behavior of the piston ring.

Title: Array antenna
Inventor: MANO SEIJI
IPC: H01Q13/08
Filed: 1989-04-13
Abstract: PURPOSE:To realize an array antenna whose gin is high in the peak direction by permitting the directional peak direction of element antennas to face within a conical degree having an apex angle 50 deg. with the rotation symmetry axis direction of a surface body as a center. CONSTITUTION:Plural element antennas 1a-1n arranged on the surface body having a rotation symmetrical axis such as a cylinder have a radiation conductor 4, a dielectric 5, a ground conductor 6, through holes 7a-7n feeding points 8a and 8b, and the space of edges 9a and 9b is lambda/4 (lambda: wavelength in free space). If the exciting phase of the feeding point 8a is assumed to be -90 deg., and the exciting phase of the feeding point 8b to be 0 deg., the peak directions of the directivity 3b of respective antennas comes to face within the conical angle having the apex angle 50 deg. with the axis (z-axis) of a cylindrical face 2 as the center but not the broad side direction of the element antennas. Thus, the gain can be improved even if a main beam is faced within the conical angle with the apex angle 50 deg. (opening angle 50 deg.) by setting the direction of the z-axis as the center.

Title: Seismoscope
Inventor: FUJIMOTO AKIRA
IPC: G01V1/30
Filed: 1990-04-10
Abstract: PURPOSE:To accurately decide earthquake waves which are different, area by area, by superposing two conditions of a vibration frequency and duration one over the other and deciding the cause of the vibration. CONSTITUTION:A sensor part 1 supplies the electric signal of the vibration to a signal processing decision part 3 through a preamplifier 2 and the decision part 3 extracts the vibration frequency and duration of the signal wave. Then a fuzzy reasoning part 4 uses the vibration frequency, amplitude, and duration of the vibration and the number of peaks of the amplitude within a specific time which have acceleration larger than a specific threshold value as fuzzy variables to find the magnitude alphaof the earthquake as the sum of sets of definition variables alpha1, alpha2, and alpha3. Further, a tuning function pat 6 initializes a weight coefficient and a learning function part 5 increases or decreases the weight coefficient of a definition variable alphai which exerts maximum influence of the calculation of the magnitude alpha according to the decision result. Then the decision part 3 decides whether the vibration is caused by the earthquake or others by fuzzy logic of the reasoning part 4 where the two condition of the vibration frequency and duration are superposed one over the other, and outputs a specific signal to an output part 7 when it is decided that the magnitude alpha is larger than the threshold value TH and the earthquake causes the vibration.

Abstract: PROBLEM TO BE SOLVED: To prevent generation of wear powder from a glass base-substrate by jetting out fluid from the side of placement surface for the glass base- substrate to thereby reduce friction of the base-substrate on the placement surface. SOLUTION: A plurality of receiving members 11a are installed in a receiption base 11 on which an air passage 11b is formed substantially in conformity with the centeral axis. In the passage 11b air with a specified pressure is made to flow through a regulation valve 15 and a solenoid valve 16. As a result, the member 11a has the same structure as the structure in which a nozzle for jetting air is embedded, and thereby the air from the nozzle is jetted to the rear surface of a glass base-substrate 10. The base-substrate 10 is slightly floated from the placement surface therefor through the air, and accordingly even if force form a side of its side surface thereof is applied to the basesubstrate 10, the friction between the base-substrate 10 and the placement surface can be reduced widely.

IPC: F28D15/02
Filed: 1979-07-25
Abstract: PURPOSE: To improve the tight fitting property, heat transfer characteristic and pressure-resisting  property of a double heat pipe for the rotary shaft of a rotating electric machine or the like, by  drawing both ends of an inner pipe to tightly close them, sealing up a working liquid and thereafter plastically deforming the inner pipe in an outer pipe to tightly fit the inner pipe therein.   
     CONSTITUTION: Both the open ends of a cylindrical metal pipe 4 are worked by spinning so that  a plug portion 14 having a small hole 13 is formed at one end by drawing and a plug 15 having  a thin injection tube 6 is also formed at the other end by drawing. The small hole 13 of the plug  14 is tightly closed by spinning work, thus manufacturing an inner pipe 8. The inner pipe is  inserted into an outer pipe 3 open at both of its ends. Both pipes are then held by a holding  jig. A liquid pressure medium such as water is introduced under pressure through the thin injection tube 6 to apply liquid pressure to expand the inner pipe 8. The inner and the outer pipes 8,  3 are tightly fitted on each other by the plastic deformation. After that, the liquid pressure  medium is removed. The pipes and the tube are cleaned up. The jig is removed. A working  liquid is then injected while gas is removed out of the pipes. The injection tube 6 is sealed up.  Said mechanism results in improving the tight fitting property and the characteristic of heat  transfer.
