Patent number: 8991417Abstract: The present invention relates to a method of controlling pressure maintenance equipment for a cooling and heating system. More particularly, the present invention relates to a method of operating and controlling, under optimum conditions, pressure maintenance equipment with multiple sensors so as to check for irregularities in the sensors which measure the same physical parameter. In the present invention, measurement values of two or more sensors are used to detect whether an abnormality has occurred in any sensor. If a sensor is determined to be abnormal, a measurement value of the abnormal sensor is excluded when determining a reference control value. Thereby, the pressure can be precisely and reliably controlled in response to actual conditions of the system.Type: GrantFiled: June 9, 2011Date of Patent: March 31, 2015Assignee: Flowtech Co.

Patent number: 8991453Abstract: A tire (1) for a motorcycle has: a groove portion (10) formed at a tread; and a block-shaped land portion (100) protrusive from the groove portion (10) toward an outside in a tire radial direction (TD). The land portion (100) has a plate-shaped small piece portion (107). Since an area with which the running wind comes into contact increases due to the small piece portion (107), the periphery of the groove portion (10) or the land portion (100) can be effectively thermally radiated. Thus, a temperature of the land portion (100) can be reduced, and even if the automatic motorcycle runs on the hard road surface over a predetermined period of time or more, it is possible to effectively restrain the lowering of required performance such as gripping force, feeling of grounding, and steering stability, which is exerted by the lowering of the rigidity of the land portion.Type: GrantFiled: December 18, 2009Date of Patent: March 31, 2015Assignee: Bridgestone CorporationInventor: Ichizo Nakamura

Patent number: 8991456Abstract: An air maintenance tire and pump assembly includes an elongate annular air passageway enclosed within a bending region of a tire, the air passageway operatively closing and opening segment by segment as the bending region of the tire passes through a rolling tire footprint to pump air along the air passageway. A pair of inline valves are positioned on respective opposite sides of an inlet junction and direct a flow of inlet air in opposite directions into the air passageway; and a pair of outlet valves are positioned at a downstream side of a respective inline valve and direct a flow of the inlet air from the downstream side of a respective inline valve toward the tire cavity. The valves are selectively opened by a direction of air flow within the air passageway which, in turn, is directionally determined by the direction in which the tire rotates.Type: GrantFiled: June 28, 2012Date of Patent: March 31, 2015Assignee: The Goodyear Tire & Rubber CompanyInventor: Thulasiram Gobinath
