摘要:
A method of manufacturing a power transmission belt having a body with a length and a cushion rubber layer in which at least one carrying member is embedded so as to extend lengthwise of the body. The method includes the steps of: extrusion molding (a) a first rubber composition including rubber with short fibers therein and (b) a second rubber composition that is different than the first rubber composition to produce a first sheet in which the second rubber composition defines at least a part of the cushion rubber layer; applying the at least one load carrying member to the second rubber composition to produce a preform assembly; and processing the preform assembly to produce a power transmission belt.
摘要:
An exhaust gas sensor (100) is configured to detect an oxygen concentration or air-fuel ratio in exhaust gas of an internal combustion engine. The exhaust gas sensor includes a sensor element (10) and a glass coating film (20). The sensor element is configured to detect an oxygen concentration or air-fuel ratio in the exhaust gas sensor. The glass coating film (20) is formed on at least part of a surface of the sensor element and capable of absorbing a Mn component contained in the exhaust gas at 700° C. The internal combustion engine uses a fuel having a Mn concentration in excess of 20 ppm.
摘要:
An exhaust gas sensor (100; 200) is configured so as to detect an oxygen concentration or air-fuel ratio in exhaust gas. The exhaust gas sensor includes a sensor element (10) and a manganese reaction layer (20). The sensor element detects an oxygen concentration or air-fuel ratio. The manganese reaction layer is formed on at least part of a surface of the sensor element and is formed of a substance containing an element capable of generating a complex oxide having manganese through reaction with a manganese oxide in the exhaust gas. The exhaust gas sensor is configured to detect an oxygen concentration or air-fuel ratio in exhaust gas of an internal combustion engine that utilizes a fuel having a Mn concentration in excess of 20 ppm.
