摘要:
A bearing support device includes a rotor, a bearing member, and a bearing holding member. The rotor rotates about a rotation center axis. The bearing member rotatably supports the rotor within a bearing hole passing through the bearing member. The bearing holding member holds the bearing member in a secure manner within a fitting hole that passes through the bearing holding member along the center axis of the rotor via an engagement force produced by tightly fitting the bearing member. The rotor and bearing member are made of a resin. An engagement section is provided for tightly fitting the bearing member into the fitting hole relative to the bearing hole to enable an engagement force produced by the tight fitting to act in a direction that does not affect an inner diameter dimension of the bearing hole.

A method of producing a diol derivative efficiently and to high purity is provided. Specifically, the present invention relates to a method of producing a diol derivative having, as a fundamental step, a step of obtaining an α-hydroxycarboxylic acid ester by reacting (i) one or more 1,2-diols or (ii) a 1,2-diol and a primary alcohol as starting material(s) with oxygen in the presence of a catalyst comprising metal loaded on a carrier, further hydrolyzing the α-hydroxycarboxylic acid ester to obtain α-hydroxycarboxylic acid, and subjecting the α-hydroxycarboxylic acid to polycondensation.

An RFID tag formed on an original includes a storage unit which stores data representing, e.g., the number of times of scan of the original and the generation from a parent original, and a transmitter/receiver which transmits and receives the data by radio. A read/write circuit receives data from an RFID tag of an original by radio. On the basis of the received data, read of the original is controlled. While the original is being read, the received data is edited in accordance with the control. The read/write circuit transmits and writes the edited data in the RFID tag.
摘要:
The present invention provides a plant-activating agent which does not cause chemical injury on plants and which improves efficiently the activity of plants. The present invention uses a substance having not less than 5% of an improved degree in reproduction of green cells measured by a specific method as the plant-activating agent.
摘要:
The present invention provides a plant-activating agent which effects no chemical injury on plant and which makes an activity of plant improve efficiently. That is to say, the present invention provides a method of activating a plant, which comprises treating the plant with a mono-alcohol having 12 to 24 carbon atoms as a plant-activating agent; use of the mono-alcohol as a plant-activating agent; and a plant-activating agent or composition comprising the mono-alcohol; optionally with a surfactant, a fertilizer component and/or a chelating agent.
摘要:
An invisible information detection apparatus includes parts that irradiate a light onto a medium, detect infrared light generated from the medium, and judge a specific pattern consisting of a combination of two areas on the medium in accordance with the detection result. One of the areas represents higher reflectance than the reflectance of the medium in substantially the same infrared wavelength region, and the other area represents lower reflectance than that of the medium. An invisible information detection method comprises an irradiation step, a detection step and a judgment step. The judgment step judges a specific pattern of a combination of two areas on the medium in accordance with the result from the detection step. One of the areas represents higher reflectance, and the other area represents lower reflectance, as compared to the reflectance of the medium, in substantially the same infrared wavelength region.

The invention provides a catalyst for partial oxidation of hydrocarbon in the presence of a reducing compound, the catalyst comprising ultra-fine gold particles immobilized on a titanium-containing oxide, and a process for preparing an oxygen-containing organic compound, the process comprising the step of oxidizing hydrocarbon with oxygen in the presence of the above catalyst and a reducing compound.
摘要:
The method of manufacturing an epoxide according to the present invention includes: a dehydrogenation step 1, in which a gas A containing an alkane is dehydrogenated, producing a gas B which contains an alkene and hydrogen; an epoxidation step 2, in which the gas B is epoxidized by use of a gas C containing oxygen in the presence of a catalyst containing gold, producing a gas D which contains an epoxide and unreacted hydrogen and oxygen; a separation step 3, in which the epoxide is separated from the gas D, leaving a gas E; and an oxygen elimination step 4, in which oxygen and hydrogen contained in the gas E are allowed to react, eliminating the oxygen and leaving a gas F. At least part of the gas F (gas F.sub.1) is recycled by returning it to the dehydrogenation step 1. Hydrogen produced in the dehydrogenation step 1 is consumed in the epoxidation step 2 and the oxygen elimination step 4, and thus does not build up in the system of reaction. Accordingly, it is not necessary to separate or eliminate the hydrogen from the system of reaction. In other words, a method can be provided which is industrially advantageous for continuously producing an epoxide from an alkane.
