摘要:
A surface-treated steel sheet is disclosed, including a zinc based plated steel sheet having thereon a surface-treated film containing titanium, nickel, aluminum and fluorine and having a film thickness of from 0.05 to 1.0 μm, the surface-treated film having a titanium deposition amount of from 0.01 to 0.5 g/m2 and containing from 0.01 to 5 parts by mass of nickel, from 0.1 to 25 parts by mass of aluminum and from 1 to 500 parts by mass of fluorine relative to 100 parts by mass of titanium. This surface-treated steel sheet does not contain hexavalent chromium in the film thereof at all and has excellent heat discoloration resistance, corrosion resistance and resistance to blackening.

摘要:
A mobile body corrosion measuring apparatus having a corrosion sensor installed in at least one portion of a mobile body, the corrosion sensor measuring a corrosion state at the portion and outputting corrosion data; a vehicle (mobile body) running speed sensor installed in the mobile body, the running speed sensor measuring a running speed of the mobile body and outputting the running speed data; and a data collection unit that acquires the corrosion data from the corrosion sensor and the running speed data from the vehicle speed sensor at the same time and collects the corrosion data and the running speed data with the corrosion data and the running speed data associated with each other. Due to above structure, a corrosion state specific to the mobile body can be accurately measured.

A traveling control system for a motor vehicle includes a detector for detecting an object which exists in front of the motor vehicle to follow a vehicle traveling ahead. The system further includes a first course determination device for estimating a first course on which the motor vehicle will travel hereafter, an identification device for identifying an first target vehicle among the objects existing on the first course, and a second course estimation device for estimating, based on the first target vehicle, a second course on which the motor vehicle will travel hereafter at least while the first target vehicle is outside of the first course. The identification device identifies a second target vehicle among vehicles which travel on the first or second courses while the first target vehicle is outside of the first course.
摘要:
In a vehicle which sets a target vehicle-interval distance, and can execute auto-cruise control for controlling the vehicle speed so as to maintain the target vehicle-interval distance, when the auto-cruise control is not executed, a vehicle-interval distance to be set by a driver is detected together with the vehicle speed at that time. A plurality of sets of the vehicle speed and vehicle-interval distance data are accumulated, and the relationship between the vehicle speed and the vehicle-interval distance is calculated. Upon execution of the auto-cruise control, a vehicle-interval distance corresponding to the vehicle speed at that time is obtained from the calculated relationship, and the obtained vehicle-interval distance is set to be the target vehicle-interval distance.
摘要:
There is disclosed a method of manufacturing a plated steel sheet with a Zn--Cr composite plating, wherein a total of 0.01 to 300 g/l of at least one type of salt having a pH buffering action in a pH range of 2 to 6 in a bath containing only zinc are added to an acidic Zn--Cr composite plating bath containing zinc ions and trivalent chromium ions to prepare a plating bath, and plating film is formed on a steel sheet using the resultant plating bath.

A fire-resistant and light-weight construction board is prepared by treating fly ash and/or paper sludge incineration ash to a swelling treatment with a mineral acid and shaping and hardening the resultant mixture.
摘要:
In a method of producing a cold-rolled steel sheet being excellent in not only the phosphate treatability but also the corrosion resistance after coating under severe corrosion environment such as hot salt water immersion test or composite cycle corrosion test, a continuously annealed steel sheet after cold rolling preferably including 0.5-3.0 mass % of Si is pickled to remove a Si-containing oxide layer on a surface layer of the steel sheet and further repickled so that a surface covering ratio of an iron-based oxide on the surface of the steel sheet is not more than 40% and preferably a maximum thickness of the iron-based oxide is not more than 150 nm, as well as a cold-rolled steel sheet produced by this method and a member for automobile using the cold-rolled steel sheet.
