摘要:
Carbon powder having low temperature calcined carbon derived from pitch adhered to a portion of the surface of natural graphite powder is obtained by solids mixing of natural graphite powder and pitch powder as a carbon precursor followed by heat treatment at 900-1500° C. to carbonize the pitch. The amount of pitch powder is such that the ratio V2/V1 of the pore volume V2 of pores having a diameter of 50-200 nm to the pore volume V1 of pores having a diameter of 2-50 nm in a pore size distribution curve obtained by analysis of the nitrogen desorption isotherm of the resulting carbon powder by the BJH method is at least 1. This carbon powder can be used as a negative electrode material for a nonaqueous secondary battery able to operate at low temperatures.

A bearing device includes a bush and a pin inserted into the bush, whereby an outer peripheral face of the pin and an inner peripheral face of the bush contact each other. At least two oil reservoirs are formed on the outer peripheral face of the pin are and elongated along the length of the pin. The interval between the reservoirs is such that an angular range centered on the pin axial center between the first reservoir and the last reservoir is not more than a center angle of 40 degrees centered on the pin axial center. At least one of the reservoirs is configured by a plurality of punctate concave portions.

Positive and negative terminals formed on a top face of a unit cell and positive and negative terminals formed on a surface of a circuit board opposed to the unit cell are electrically connected to each other by connectors. The connectors each include an elastic body formed from an elastic material, and a conductor which is placed so as to be exposed on upper and lower surfaces of the elastic body and which serves for electrically connecting those exposed portions to each other. By elastic restoring force of the elastic body generated by elastic compression of the elastic body between the terminals, the upper and lower surfaces of the connectors are put into press contact between the opposing positive and negative terminals of the unit cell and the circuit board, by which their electrical connection is maintained.

摘要:
The object of this invention is to elucidate the factors involved in the regulation of AGE (advanced glycation endproducts, which are produced in a living body accompanied with diabetes and aging) and RAGE (the receptor for AGE), in order to facilitate investigation on the biological activities, physiological phenomenon and diseases related to AGE and RAGE. Plural molecular species are known to exist for RAGE, and among such molecular species, soluble RAGE exhibits the activity to modulate interaction between AGE and transmembrane-type RAGE. Using this soluble RAGE or a nucleic acid encoding it, the soluble RAGE can be measured, in addition, investigation on various physiological phenomenon, biological activities, and diseases related to interaction between AGE and RAGE can be performed to facilitate development a medicine having further efficacy.
