摘要:
A vehicular cooling device supporting apparatus has a radiator support lower 14 formed with a plurality of support-side connecting portions 32 and 34 for altering connecting positions to radiator support sides 16 and 18. This enables a layout position of a radiator main body 20 to be altered depending on size of an engine to use component parts in common. Placing the radiator main body 20 in a rearward position when the engine is small in size can suppresses damage to the radiator main body 20 upon collision of a vehicle at a low vehicle speed. In this case, it is suffice for the connecting positions of the radiator support lower 14 to the radiator support sides 16 and 18 to be altered in a vehicle fore and aft direction. Thus, the cooling device supporting apparatus can be constructed simply at the low cost with a minimum number of component parts.

A hot press-formed article having improved corrosion resistance and coating adhesion when coated is obtained by hot press forming of a zinc-based plated steel material. It has a zinc-based plating layer comprising an iron-zinc solid solution phase and atop it a zinc oxide layer. The average thickness of the zinc oxide layer which is the outermost layer is at most 2 μm. A hot press-formed article having a good appearance and excellent corrosion resistance, coating adhesion, post-coating corrosion resistance, and weldability has a layer (2) consisting essentially of an iron-zinc solid solution phase atop a base material steel sheet (1). It also has a zinc oxide layer (3) with an average thickness of at most 5 μm as an uppermost layer, but it does not have a substantial amount of an iron-zinc intermetallic compound phase. The total amount of Al contained in the iron-zinc solid solution layer (2) and the zinc oxide layer (3) is at most 0.5 g/m2, and/or the total amount of Al oxides contained in these layers is at most 5 mg/m2.

摘要:
A hot press-formed member having stable strength and toughness is manufactured from a high strength steel sheet by hot press forming. In the cooling stage during hot press forming, the cooling rate is at least the critical cooling rate until the Ms point is reached and it is then in the range of 25-150° C./s in the temperature range from the Ms point to 200° C. The Vickers hardness of the hot pressed member is less than the value of (maximum quenching hardness −10) and at east the value of (maximum quenching hardness −100).

SP6 bacteriophage RNA polymerase is produced by cultivating a new microorganism (particularly new strains of Escherichia coli) harboring a plasmid that carries SP6 bacteriophage RNA polymerase gene and recovering SP6 bacteriophage RNA polymerase from the culture broth. SP6 bacteriophage RNA polymerase gene is provided as are new microorganisms harboring a plasmid that carries SP6 bacteriophage RNA polymerase gene.
摘要:
A method for the fluorescent labelling of a sugar or a sugar chain by labelling the reducing end of the sugar or sugar chain with a fluorescent substance, wherein the improvement comprises first forming a Schiff base by reacting the surgar or sugar chain with the fluorescent substance in the presence of an acid which is substantially free from water, and second, reducing said Schiff base.

A method is provided for the detection of a disease associated with the metabolic abnormality of L-fucose in a subject. The concentration of free L-fucose in a specimen from the subject is determined and the determined concentration is compared with a normal concentration of free L-fucose.
摘要:
A method is provided for the quantitative determination of L-fucose in a sample solution. According to the method an L-fucose dehydrogenase having its optimum pH around neutrality is allowed to act upon the sample solution in the presence or absence of an .alpha.-L-fucosidase, and the amount of reduced nicotinamide adenine dinucleotide thus formed is measured.

Phenopicolinic acid is produced by culturing a strain of Paecilomyces. The compound, which may be alternatively named as 5-(4-hydroxybenzyl)-2-pyridinecarboxylic acid, is a hypotensive agent.
摘要:
A vehicular radiator supporting apparatus 10 has a pair of radiator support sides 16 and 18 connected to a radiator support upper 12 to be pivoted about a predetermined pivot axis O. To the pair of radiator support sides 16 and 18, a pair of abutting brackets 34 and 36 are integrally fixed at positions corresponding to a height of the bumper reinforcement 54, and they are connected to a pair of vehicle-body side brackets 38 and 40. When applied with a load exceeding a predetermined value and acting rearward of the vehicle, the pair of abutting brackets 34 and 36 are pivoted about the pivot axis O integrally with the pair of radiator support sides 16 and 18 to be displaced rearward of the vehicle. Thus, the vehicular radiator supporting apparatus 10 itself in addition to the radiator main body 20 is prevented from being damaged.
