摘要:
A three-dimensional light reflection plate that can successfully prevent deformation of the light reflection plate, reduce initial cost and product cost, and facilitate increase in size and reflectance. The light reflection plate includes a bottom plate in which a plurality of mutually parallel slit holes are formed on a flat, light-reflective plate material and a mountain plate that is rectangular from a planar view of which a width direction cross-sectional shape is a mountain shape and in which insertion sections are formed in both width-direction end sections. The mountain plate is fixed to the bottom plate by the insertion sections of the mountain plate being inserted into the slit holes of the bottom plate.

A bearing capable of enduring long use in a four-cycle engine is provided. The bearing is provided with a hollow cylindrical retainer 1 made of steel and rotatably retaining a plurality of needle rollers 4. The retainer 1 is subjected to a sulphonitriding treatment to form a sulphonitrided layer 11 on a surface of the retainer 1. The sulphonitrided layer 11 is made up of a nitrogen-compound single-layer 12 deposited on the surface of the retainer 1 made of steel, and a sulfur-compound porous layer 13 formed continuously on the nitrogen-compound single-layer 12 and forming a surface layer of the sulphonitrided layer 11.

A vehicle is provided with a shift control device including a rolling angular velocity sensor for detecting a rolling angular velocity of a component of the vehicle, and a steering-angle angular velocity sensor for detecting a steering-angle angular velocity of a handlebar of the vehicle. The shift control device is operable to inhibit shifting of a gear ratio of a continuously variable transmission during rolling operation of the vehicle when detection signals from the rolling angular velocity sensor and the steering-angle angular velocity sensor respectively are equal to or greater than predetermined reference values.

The presence or absence of methylation of C's in CpG dinucleotide in a sample DNA that contains a target sequence including the CpG dinucleotide is detected as follows. Multiple kinds of capture oligonucleotides immobilized on a base material and including: an oligonucleotide having a nucleotide sequence complimentary to or identical to a nucleotide sequence corresponding to the target sequence in which all of C's other than C's in the all of CpG dinucleotide are replaced with T's; and an oligonucleotide having a nucleotide sequence complimentary to or identical to a nucleotide sequence corresponding to the target sequence in which all of C's are replaced with T's are hybridized with the sample DNA in which non-methylated C's have been converted into U's by deamination or an amplification product thereof, and the presence or absence of methylation is detected based on the result of the hybridization.

In an optical fiber array (1) which has a V-groove substrate (2) formed in its surface (2a) with V-grooves (3) for arranging optical fibers, a plurality of optical fiber cores (61) fixedly bonded in each individual V-groove (3) of the V-groove substrate (2), and a pressure plate (4) fixedly bonded to surfaces of the optical fiber cores (61), an adhesive comprising a resin composition (component A) having an OH group after curing and a filler (component B) is used to fixedly bond the V-groove substrate (2), the optical fiber cores (61), and the pressure plate (4). This adhesive has a glass transition temperature that is somewhat lower than the ambient test temperature and possesses somewhat higher elasticity. Therefore, large internal stress does not occur in the adhesive even under conditions of high temperature and high humidity. Consequently, no peeling occurs as a result of moisture penetration since gaps cannot form between the pressure plate (4) and the adhesive.
摘要:
A method for producing highly unsaturated fatty acids comprising culturing a microorganism, belonging to the genus Mortierella and having resistance to a carbon source, in a medium having a carbon source concentration of at least 4% by weight, and collecting highly unsaturated fatty acids from the cultured products. Culturing the microorganism for about a week gives at least about 7 g/L of highly unsaturated fatty acids.

A twin-clutch transmission wherein a center distance between input shafts and an auxiliary speed-change shaft can be shortened and the number of gears can be reduced. A twin-clutch transmission is provided which includes a first input shaft and a second input shaft, an auxiliary speed-change shaft, and a plurality of gear pairs. The first and second input shaft are connected, through a first clutch and a second clutch, respectively, to an input element, and disposed on the same axis. The auxiliary speed-change shaft is disposed parallel to the first and second input shafts. The plurality of gear pairs are provided between the first and second input shafts and the auxiliary speed-change shaft. An input path from the input element to the first clutch is different from that to the second clutch, and primary ratios of the input paths are set to values, respectively, different from each other.

A strainer device for a fuel tank includes a sucking passage member provided with a passage opened in the fuel tank; a filtering member attached to the sucking passage member for covering a hole of the passage; and a conduit connecting portion extending outside the fuel tank for connecting a conduit for guiding fuel passing through the filtering member. The conduit connecting member is attached to the sucking passage member, so that a concave portion is formed at a connecting portion for receiving a check valve for preventing the fuel from flowing back from outside of the fuel tank.
