A measuring apparatus for speedily measuring a bearing height is disclosed. A plunger of a movable cylinder is extended with a test load P by a constant pressure applying mechanism S. The movable cylinder is ascended from a receded position to a measuring position by a slide cam. A bearing half W disposed on a pushing member is fitted in a receiving cavity of a standard tool in such a manner that an end of the bearing half W slightly protrudes from the receiving cavity portion. When the movable cylinder slightly exceeds the measuring position, a plunger is pressed for the length of the end protruded from the receiving cavity portion. At this point, the bearing half W is held with the test load P. Thus, the bearing height can be immediately measured by a length sensor.

A high dielectric nanosheet laminate is produced by laminating nanosheets, each of which has a thickness of 10 nm or less and is formed of an oxide that has a perovskite structure wherein at least four NbO6 octahedrons, TaO6 octahedrons or TiO6 octahedrons are included in a unit lattice. Consequently, the high dielectric nanosheet laminate is capable of achieving a high dielectric constant and a satisfactory insulation property, which are preferable for high dielectric nanosheet multilayer capacitors or the like, at the same time even if formed very thin.

The present invention relates to fine hollow powder with a titanium oxide shell, obtained by spray drying an exfoliated titania sol, and thin flaky titanium oxide powder obtained by pulverizing the fine hollow powder, and also to processes for producing the same. The present fine hollow powder and thin flaky titanium oxide powder have a distinguished dispersibility and are useful for additives to cosmetics, pigments, paints, etc., and the present fine hollow powder also has a distinguished flowability and is useful for seed particles for flow measurement.
摘要:
Disclosed is an organic dispersion comprising a flaky titanium oxide particle having a high crystallinity and high light permeability contained in an organic solvent. The dispersion can be prepared by a method comprising preparing an aqueous dispersion of a flaky titanium oxide particle containing an organic cation, centrifuging the aqueous dispersion to produce a precipitate, and adding the precipitate to an organic solvent, or a method comprising lyophilizing the aqueous dispersion to produce a lyophilized material and mixing the lyophilized material to an organic solvent. When the organic dispersion is used, it becomes possible to form a film comprising a monolayer of a titanium oxide nanosheet densely arranged therein by such a simple manner that the dispersion is coated on a base material and drying the dispersion. The film thus produced has a photocatalytic activity and a super-hydrophilic property.

An all-solid lithium secondary battery has excellent reliability including safety. However, in general, its energy density or output density is lower than that achieved by liquid electrolyte systems.The all-solid lithium battery includes a lithium ion-conducting solid electrolyte as an electrolyte. The lithium ion-conducting solid electrolyte is mainly composed of a sulfide, and the surface of a positive electrode active material is coated with a lithium ion-conducting oxide. The advantages of the present invention are particularly significant when the positive electrode active material exhibits a potential of 3 V or more during operation of the all-solid lithium battery, i.e., when redox reaction occurs at a potential of 3 V or more.
