摘要:
There is disclosed an electron microscope equipped with a magnetic microprobe. The microscope can apply a strong electric field to a local area on a specimen made of a magnetic material. The magnetic flux density per unit area of the microprobe is high. The microscope includes a biprism for producing interference between an electron beam transmitted through the specimen and an electron beam passing through a vacuum. The specimen is held to a holder. The microprobe is made of a magnetic material and has a needle-like tip. The microscope further includes a moving mechanism capable of moving the microprobe toward and away from the specimen.

A 1-butene polymer satisfying the following (1), (2) and either (3) or (3′): a process for producing the polymer; a resin modifier comprising the polymer; and a hot-melt adhesive containing the polymer. (1) The intrinsic viscosity [η] as measured in tetralin solvent at 135° C. is 0.01 to 0.5 dL/g. (2) The polymer is a crystalline resin having a melting point (Tm-D) of 0 to 100° C., the melting point being defined as the top of the peak observed on the highest-temperature side in a melting endothermic curve obtained with a differential scanning calorimeter (DSC) in a test in which a sample is held in a nitrogen atmosphere at −10° C. for 5 min and then heated at a rate of 10° C./min. (3) The stereoregularity index {(mmmm)/(mmrr+rmmr)} is 30 or lower. (3′) The mesopentad content (mmmm) determined from a nuclear magnetic resonance (NMR) spectrum is 68 to 73%.
摘要:
The present invention provides a technique for, in the case in which a failure has occurred in a shared memory, controlling a period of a pseudo through operation to reduce a period in which performance of a disk array device falls. Control information is divided into management information, which is required to be duplexed, and directory information, which is only required to simplexed, and the management information and the directory information are stored in separate shared memories. In the case in which a failure has occurred in the shared memory of an expanded memory unit (Option) storing the directory information, the directory information is reestablished in the shared memory of a basic memory unit (Basic). The pseudo through operation is cancelled at the point when the directory information is reestablished. After a package of the expanded memory unit is replaced with a normal product, the directory information is reestablished again. Management information managed in the other cluster is copied to the shared memory of the basis memory unit to complete maintenance and recovery work.

An aquarium-cleaning device, particularly an aquarium-cleaning device in which spent grain charcoal is used as formed charcoal. The formed charcoal provided by drying, forming, and carbonizing organic substances produced in food industries is used as a microorganism carrier. Such problems with a conventional device that the structure of the aquarium-cleaning device is complicated, the washing operation thereof is troublesome, and a filter medium must be frequently replaced can be solved by using the spent grain charcoal performing higher water-quality purification than a conventional activated charcoal as an aquarium-cleaning material.

An active region on a semiconductor substrate is electrically isolated by trench isolation. A structure of the trench isolation is constituted of: a trench; a silicon oxide film formed on the inner wall of trench; an oxidation preventive film formed between silicon oxide film and semiconductor substrate; and a filling oxide film filling trench. Gate oxide film is formed by oxidation having a high capability by which radicals of at least one kind of hydrogen radicals and oxygen radicals are generated. Thereby, gate oxide film is formed so as to have a almost uniform thickness such that a thickness of a region directly above oxidation preventive film and a thickness of a region directly below gate electrode are almost the same is each other. According to the above procedure, there are obtained a semiconductor device having good transistor characteristics and a fabrication process therefor.

In a rectangular alkaline storage battery, the sides of negative cores of negative electrode plates 10, which are disposed at the outermost positions of the group of electrode plates and oppose an outer casing can 40, are exposed. The pore ratios (ratio of total area taken up by pores to area of electrode plate) of the exposed cores must be made lower than those of the other unexposed cores. The pore ratio of the exposed negative core is specified as falling within a range of 10% to 40%. As a result, the negative electrode plates 10 are improved in binding strength, thereby inhibiting exfoliation of an active material. Further, there can be obtained a large rectangular alkaline storage battery which has superior permeability for a gas which would arise in the battery, an improved capacity ratio, and greater volumetric energy density.

There are discolsed a pesticidal composition containing a water-insoluble alginate, which is prepared by treating a solid composition containing (a) a pesticidally active ingredient which is a pest-controlling active ingredient or a plant growth-regulating active ingredient and (b) an alginic acid or a water-soluble alginate with an aqueous solution containing a divalent or polyvalent cation which can convert said alginic acid or water-soluble alginate into a water-insoluble alginate. Also disclosed is a pesticidal composition containing a water-insoluble alginate, which is prepared by coating a solid substance containing the pesticidally active ingredient with a water-insoluble alginate. The composition of the invention has excellent sustained-release effects of the pesticidally active ingredient.
