摘要:
The fine barium titanate particles of the present invention have an average primary particle diameter of from 10 nm to less than 20 nm, a sphericity of 1.00 to 1.18, and a ratio of an average secondary particle diameter to the average primary particle diameter of 0.7 to 6.0. The fine barium titanate particles of the present invention can exhibit a small behavior particle diameter and can be readily monodispersed notwithstanding very fine particles, and as a result, can be suitably used as various dielectric materials because the particles are free from aggregation therebetween and have an excellent dispersibility.

When a downshift is performed while a vehicle travels in a coasting state, a determination is made as to whether or not a fuel cut recovery will be performed. When a fuel cut recovery will be performed, an offset oil pressure is set and an initial oil pressure set after raising an oil pressure of an engagement side frictional engagement element to a pre-charge oil pressure is set at an oil pressure obtained by subtracting the offset oil pressure from a reference initial oil pressure.

A motor includes a stator formed by assembling plural divided-stator-members—each one of the members having a tooth—into an annular shape, and a rotor facing the stator. The divided stator members are formed by laminating plural core sheets and bonding at least parts of end faces along the laminating direction of the core sheets. This structure allows forming a lamination of the core sheets without welding, which avoids damaging electrical insulation between each core sheet. Eddy current thus does not increase at an inner rim of the stator, where magnetic flux intensely changes. The motor efficiency is, therefore, not adversely affected. As a result, a small, efficient and high performance motor in a simple structure is obtainable. A compressor employing the same motor and enjoying the advantages of the motor is also obtainable.

Disclosed is a novel spirooxazine compound having excellent durability which changes into a colored form upon irradiation with the light containing ultraviolet rays such as of sunrays or the light from a mercury lamp, the change being reversible.
摘要:
A photochromic compound of the present invention is a spiroxazine compound represented by the following formula: ##STR1## wherein R.sup.1 to R.sup.3 represent a monovalent organic group such as alkyl group, Y represents a fused heterocyclic aromatic hydrocarbon group or an unsaturated heterocyclic group if R.sup.1 and R.sup.2 are both methyl groups, and represents an aromatic hydrocarbon group or unsaturated heterocyclic group if R.sup.1 and R.sup.2 are other than the above mentioned. This compound shows an excellent photochromic characteristics even at high temperatures not less than ambient temperature.

In a mold to be hardened by a CO.sub.2 gas, a mold binder material comprising a combination of polymers containing carboxyl groups, at least one of multi-valent metal oxides and multi-valent metal hydroxides, and resins of polyvinyl alcohol group, and at least one of sodium salt of gluconic acid and polyhydric alcohols or a mold binder material comprising a combination of polymers having carboxyl groups, at least one of multi-valent metal oxides and multi-valent metal hydroxides, and at least one of sodium salt of gluconic acid and polyhydric alcohols is provided. By use of the present binder material, the following various effects can be obtained: (1) easy preparation of mold sand, (2) easy removal of the binder material by water washing even if bodies or clothes are fouled by the binder material, (3) a longer working time of mold sands, (4) a higher mold strength, (5) an improved working atmosphere at shaping of the mold, (6) an improved production efficiency of molds, (7) the desired mold strength being obtained with a smaller amount of CO.sub.2 gas used, etc.

The present invention has the objective of offering drug for treating abnormalities in bone marrow which corrects the biological balance in the bone marrow, in particular which has the effect of suppressing inflammatory cell infiltration and suppressing cell growth-differentiation factor increase. The present invention relates to drug for treating abnormalities in bone marrow which has, as an effective component, a methanebisphosphonic acid derivative, ester thereof, medicinally acceptable salt thereof, or a hydrate of these. The methanebisphosphonic acid derivatives of the present invention show an outstanding bone marrow abnormality therapeutic effect, so efficacy can be expected in the prevention and treatment of rheumatoid arthritis, multiple myeloma, osteomyelitis and other bone marrow abnormalities. Furthermore, application can also be expected in the prevention and treatment of hypoplastic anaemia, myelocytic leukaemia and other such haematopoietic disorders.
