A wheel support bearing assembly, which enables an increase in the strength and the fatigue strength of its wheel mounting flange or vehicle body fitting flange against high stress and repeated stress and the suppression of the increase of the number of processes, includes an inner member and an outer member rotatable relative to each other through rolling elements. The flange is formed on the inner member or the outer member, for example, a hub. A component part having the flange is a hot-forged product of steel in which a matrix portion is formed as a standard structure and the non-standard structural portion is formed on the surface of the flange. The non-standard structure is formed of either of a fine ferrite/pearlite structure, an upper bainite structure, a lower bainite structure, and a tempered martensite structure, or mixture of two or more of these structures.

A system for providing a registered land asset includes a property transaction database in communication with a computer network the property transaction database provides information related to transactions associated with each registered land asset parcel, each land parcel having a registered land asset identifier representing global coordinates particular to the parcel. The system also includes a location characteristic database in communication with the computer network. The location characteristic database provides socioeconomic data regarding the location wherein the land parcel associated with the registered land asset is situated. A registered land asset contract may give a leaseholder an option to purchase the land by the end of a given term. A computer receives data from the property transaction database and the location characteristic database via the computer network and calculates prices and values associated with a registered land asset contract associated with the land parcel and a registered land asset contract is recorded in association with the land asset identifier corresponding to the land parcel in an electronic land title registry in communication with the computer network.

PROBLEM TO BE SOLVED: To produce a medium/high carbon steel sheet excellent in stretch- flange formability by the use of a general medium/high carbon steel without the addition of special elements. SOLUTION: A hot rolled steel plate, composed of a steel containing 0.1 to 0.8 mass % C and having a pro-eutectoid ferrite+pearlite structure in which the pro-eutectoid ferrite area ratio (%) is regulated to a value not lower than the value of F determined by equation F=0.4×(1-mass % C/0.8)×100, is cold rolled at >=15%, if necessary. The resultant cold rolled steel sheet is subjected to annealing where the following treatments are performed continuously: temperature raising where temperature rise rate from 650 deg.C up to a temperature in the range between Ac1 and Ac1 +100 deg.C is regulated to (5 to 80) deg.C/h; first-stage heating and holding where holding is done in the temperature range between Ac1 and Ac1 +100 deg.C for 0.5 to 20 hr; temperature lowering where temperature fall rate from the first-stage holding temperature down to a temperature in the range between Ar1 -80 deg.C and Ar1 is regulated to (5 to 30) deg.C/h; and second- stage heating and holding where holding is done in the temperature range between Ar1 -80 deg.C and Ar1 for 2 to 60 hr.

PROBLEM TO BE SOLVED: To make outputtable the residual capacity of a battery according to the usage state of the battery by installing a data storage means and referring to the total discharge capacity up to a discharge stop voltage which is changed according to a discharge current value by using a discharge current value at this time. SOLUTION: As an element to judge the degradation of a battery, the degradation can be judged by a reduction in the actual total discharge capacity. At the time of full charging operation of one immediately before, the total discharge capacity which is discharged up to a discharge stop voltage since the full charging operation is integrated by an integrated-discharge-amount calculation program 7a, and the total discharge capacity at this time is stored in a memory 7. The total discharge capacity is divided into ranges at four stages regarding the total discharge capacity to be reduced. It is judged at which stage the battery is degraded, and a degradation degree L is decided. A residual-capacity calculation program 7c refers to a degradation-degree- correspondence total discharge capacity table 7e on the basis of a current value (i), at the present, and a temperature value T, at the present, which are stored in the memory 7 and on the basis of the detected degradation degree L. A table which corresponds to the degradation degree L is selected, and the total discharge capacity Qa which corresponds to the degradation degree L is calculated.
