Title: Method for measuring residual stress
Inventor: HAYASHI MAKOTO
IPC: G01L1/25
Filed: 1995-05-31
Abstract: PURPOSE: To measure a residual stress in a structure with high accuracy by finding the elastic modulus of a test piece in advance by measuring the stress of the test piece when a load is mechanically applied to the test piece, and the strain of the test piece caused by neutron diffraction. CONSTITUTION: Neutrons generated from a nuclear reactor enter a monochromator 3 trough a guide tube 2 and, in the monochromator 3, the neutron rays are diffracted, made even in wavelength, and monochromatized. The monochromatized neutron rays are made incident to a sample 6 to be measured through an incident beam slit 5 after passing through a guide tube 4. By using a test piece, the stress of the test piece when a load is mechanically applied to the test piece and the strain of the test piece caused by neutron diffraction are measured in advance and the elastic modulus against a surface of diffraction to be measured is found from the relation between the stress and strain measured from the test piece. Then the triaxial strain measured by utilizing the neutron diffraction is converted into three axial directions by using the elastic modulus based on the Hooke's law.  Therefore, the residual stress in a structure can be measured with high accuracy by taking the surface-of-diffraction dependency of the elastic modulus into consideration.

Title: Self-adhesive tape
Inventor: KURAHASHI YOSHIO
IPC: C09D11/00
Filed: 1983-07-21
Abstract: PURPOSE:To provide a self-adhesive tape which shows pressure sensitive adhesion only between formed films, prepd. by treating a base tape coated with an aqueous soln. of a rubber latex and a water-soluble adhesive, with an anti-blocking agent on one or both sides. CONSTITUTION:A homogeneous aqueous soln. of a water-soluble adhesive and a rubber latex in a blend ratio of 0.48-1.80/1 by weight, is applied to a base tape on one or both sides thereof and, after drying, the coated surface is treated with an anti-blocking agent (e.g. high purity SiO2 in fine powder or polymethylsiloxane). The coating film on the surface of the self-adhesive tape has high adhesive strength to another coating film against tensile force in a horizontal direction but can be readily peeled off at right angles and shows no adhesive power to other materials. For example, a tape having the coating layers on both sides is wound round an article for tight self-adhesion of overlapped areas to effect packaging or bundling.

Abstract: PURPOSE:To obtain an excellent image by making a distance between an expos ing position and a means for bringing a sensitive member into tight contact with a receptive member longer than the length between the tip of the cut sensitive member and the back end of an image surface. CONSTITUTION:The length between the exposing position and the means for tightly contacting he sensitive member with the receptive member is made longer than the length between the tip of the cut sensitive member and the back end of the image surface. Namely, when the edge of a carried negative film 64 is detected by a sensor 25, the negative film 64 is cut in a sheet shape by bringing rotating blade 20a into contact with a fixed blade 20b, and the distance from the cutting position to the exposing position A is set longer than the distance from the tip of a latent image formed on a negative sheet to the back end of the negative sheet. Since the variation of the motion of the sheet at the time of bringing the sensitive member into tight contact with the receptive member does not influence the image, the excellent image can be obtained.

In the PWM circuit section 21, the error signal is compared with the sawtooth wave synchronized with the clock signal of the clock signal generator 24 to generate the pulse width modulated signal to be inputted to a waveform forming section 20. In the waveform forming section 20, the drive signals of four systems are generated from this pulse width modulated signal to controllably drive the DC/AC inverters 13, 14. As a result, low distortion waveform can be supplied and drooping operation can be realized without generating distortion of output voltage waveform during overload operation.
