    摘要： A vibration wave driving apparatus includes a vibration member in which an electro-mechanical energy conversion element is fixed to an elastic member, and a contact member pressed against a sliding part provided in the vibration member, so as to be kept in contact therewith. The vibration wave driving apparatus is configured to supply alternating signals in a predetermined driving frequency band to the electro-mechanical energy conversion element, thereby generating a predetermined natural vibration mode in the elastic member to drive the contact member. In the apparatus, the natural vibration mode is generated in the elastic member, a natural frequency of another vibration mode different from the natural vibration mode is detected, and a stiffness of the support member is altered if the natural frequency of the other vibration mode detected is included in the driving frequency band.

    摘要： An exhaust gas purifying system for an automotive internal combustion engine includes a NOx treating catalyst for reducing NOx disposed in an exhaust gas passageway of a combustion device, to reduce NOx in presence of reducing components in exhaust gas. Additionally, a hydrogen enriching device is disposed upstream of said NOx treating catalyst with respect to flow of exhaust gas from the combustion device and arranged to increase a ratio of hydrogen to total reducing components in at least one of combustion gas and exhaust gas so as to meet relations represented by following formulae (1) and (2), when reduction of NOx is carried out by the NOx treating catalyst: [H2/TR]d>[H2/TR]u  (1) [H2/TR]d≧0.3  (2) where [H2/TR]u is a ratio between a concentration [H2]u of hydrogen and a concentration [TR]u of total reducing components in at least one of exhaust gas in the exhaust gas passageway upstream of the hydrogen enriching device and combustion gas in a state before undergoing the hydrogen ratio increasing by said hydrogen enriching means; and [H2/TR]d is a ratio between a concentration [H2]d of hydrogen and a concentration [TR]d of total reducing components in exhaust gas in the exhaust gas passageway upstream of the NOx treating catalyst and downstream of the hydrogen enriching device.
