Filed: 1996-12-16
Abstract: PROBLEM TO BE SOLVED: To visually observe the amount of corrosion of members of a vessel, etc., even in a driving state, by holding a test piece in a detection segment which is formed of the same material as that of the member constituting the detection segment to have a different thickness at an end face. SOLUTION: A disk-liek corrosion amount-detecting plate 1 is processed for the same steel plate as used for a ballast tank and a cargo warehouse. A inclined face is formed at one face, so that a thickness of a circumference as an end face differs. Partition lines 3, 3 are arranged to be symmetric to each other with respect to a diameter A-A running from the thickest part to the thinnest part of the circumference of the plate 1. The plate 1 is set to the ballast tank or cargo warehouse by a hole 2. The abrasion amount-detecting plate 1 is corroded in the same manner as the ballast tank or cargo warehouse, and the thickness is reduced. Since the thickness of the end face on the circumference of the corrosion amount-detecting plate 1 differs, the plate 1 corrosion and dissolved to disappear from the thinnest part even when the plate 1 is corroded with the same amount of corrosion.  Accordingly, the amount of corrosion of the steel plate of an actual structure can be visually observed and easily detected during the navigation of a vessel.

Title: Temperature control device for cylinder wall of engine
Inventor: SUGIMOTO MITSURU
IPC: F01P7/16
Filed: 1999-11-26
Abstract: PROBLEM TO BE SOLVED: To reduce friction losses generated at a sliding portion of a cylinder wall and a piston to a minimum, by controlling the temperature distribution to be suitable for the cylinder wall of an engine. SOLUTION: A cylinder block 11 comprises an upper water jacket 19 and a lower water jacket 20. Cooling water, of which temperature is raised passes through the upper water jacket 19, and then is supplied to the lower water jacket 20. The opening degree of a first cooling water flow rate control valve 25 is controlled so that an upper cylinder wall temperature Tt becomes a target upper cylinder wall temperature. The opening degree of a second cooling water flow rate control valve 27 is controlled and a lower cylinder wall temperature Tb becomes a target lower cylinder wall temperature.  Since the target lower cylinder wall temperature is set at sufficiently high temperature within a range, where oil film of lubricating oil is secured for a portion from an intermediate portion of the cylinder wall 12a up to a bottom dead center of the piston, the viscosity of the lubricating oil is decreased to keep the friction loss of the sliding portion and the cylinder wall 12a and the piston 14 to a minimum, and accordingly, the output of the engine can be increased, and fuel consumption and lubricating oil consumption can be reduced.
