A strain detector which is improved in corrosion resistance and moisture resistance and is high in reliability. The strain detector comprises a driven member, a magnetic shielding layer of a non-magnetic or diamagnetic material selectively formed on the driven member, a magnetic layer formed at a portion of the driven member at which the magnetic shielding layer is not formed, and a detecting coil provided corresponding to the magnetic layer. The magnetic layer may be formed in such a manner as ...

A strain detector includes a passive member for receiving an external force, magnetostrictive layers formed on a surface of passive member and made of a magnetic material containing nickel and at least one kind of metal sulfide produced from reaction of a metal more reactive with sulfur than nickel with sulfur as an impurity, and a detection coil provided close to an exterior of magnetostrictive layers and used for detecting variations of permeability caused by strain of the magnetostrictive lay...

A strain detector to be attached to the shafts of devices such as engines, motors, electromagnetic clutches. First and second magnetic layers are disposed on the driven shaft so as to change permeability with a mechanical strain in the shaft. First and second detecting coils are wound around the first and second magnetic layers so as to be in a noncontact state therewith. Detecting means detects outputs of the detecting coils corresponding to the change in permeability. Furthermore, the driven s...

A strain gage includes four gages that constitute a bridge circuit, and at least one resistance device which is used to adjust the offset voltage of the bridge circuit formed by the four gages. The resistance device is disposed on the strain gage between one of the gages making up the bridge circuit and a terminal thereof. Finally, each resistance device disposed on the strain gage has a series of resisting elements which vary in size and which are connected in parallel fashion.

This is to introduce a strain sensor of high quality and excellent durability. This strain sensor is composed of a basic metal body, a crystallized glass layer formed over the surface of the basic metal body, and a resistance element that changes its resistance value by strain changes and is built on the glass layer surface. By this structure, where the crystallized glass layer fired at a high temperature is employed, both of the composition, the basic metal body and the glass layer, are fused w...

The present invention includes a substantially pure bacterium, Flavobacterium spp., which produces compositions having unique anti-tumor and anti-inflammatory properties. The present invention includes methods for treating tumors in mammals comprising administering to such mammals a therapeutically effective amount of a composition of the invention.

A strain indicator of the type wherein a change in length of a strain member produces a change in color of a visual indicator. An indicator area and a light-absorbing indicator fluid are encapsulated in a member that also includes a window. The capsule is fastened to the strain member with an adhesive. A change in length of the strain member causes the indicator area to become separated from the window with the result that light-absorbing indicator fluid is caused to flow between the indicator a...

A strain sensor includes a sensor section having a magnetic material provided on one surface of a conductor, the magnetic material being formed integrally with the conductor and having a magnetic strain constant with an absolute value larger than 1.times.10.sup.-7, a fixing mechanism which fixes at least a part of the sensor section, an inductor disposed in a surface side of the sensor section which is opposite the surface on which the magnetic material is provided, the inductor being disposed o...

The present invention relates to new baker's yeast Saccharomyces cerevisiae strains which have improved temperature tolerance and/or keeping quality. An example of such a strain has been designated YTTS and deposited AGAL and accorded accession No. N93/10504.

A strain detector in which a pair of magnetic layer patterns (5, 6) made of a magnetically permeable soft magnetic material are attached to a driven shaft (1) and a pair of detection coils (8, 9) are disposed to surround the respective magnetic layers for detecting a change in magnetic permeability of the magnetic layers which is caused when an external force is applied to the driven shaft. A magnetic yoke (15 or 16) is disposed around each of the detection coils (8 or 9) for promoting the passa...
