The present invention provides an AP-1 activation inhibitor, a NF-kappaB activation inhibitor, an inflammatory cytokine production inhibitor, a production inhibitor for matrix metalloprotease or an inflammatory cell adhesion factor expression inhibitor, which contains a heterocyclic compound or a pharmaceutically acceptable salt thereof as an active ingredient. The rectifier has an antenna element, a tuning capacitor, a coupling capacitor, first and second rectifying diodes, and a storage capacitor. The pivot hole structure and the guiding portion are disposed on the body. The metering valve device is configured to dispense a portion of the additive from the dispensing chamber into a housing by a second one-way valve. The method further comprises detecting a fault in a volume of data stored in the mass storage subsystem, determining a severity of the fault, and selecting a course of action in response to the fault, based on the severity of the fault. The torsion bar spring can have a divided construction and the spring element can be clamped in between the two parts of the torsion bar spring, in which case these two parts of the torsion bar spring can be mutually rotatable by way of an actuator.
