摘要： An engine (8) is mounted to a vehicle body by means of vibration isolating mounts (8E), and a support member (15) is mounted to the engine (8). Vibration isolating members (20) are provided between this support member (15) and a mounting bracket (17) mounted to an exhaust gas treatment device (16). Accordingly, even in cases where the engine (8) has generated high-frequency vibrations, these vibrations can be damped by the vibration isolating mounts (8E) and the vibration isolating members (20). In consequence, treatment members constituting the exhaust gas treatment device (16) , such as a catalyst, a filter, and a sensor, can be protected from the vibrations of the engine (8). In addition, as the exhaust gas treatment device (16) is provided with the mounting bracket (17), the vibration isolating members (20) can be reliably mounted to the exhaust gas treatment device (16) by means of the mounting bracket (17).

摘要： The present technique relates to a receiving device, a receiving method, and a program that are designed to improve reception performance. A receiving device according to one aspect of the present technique includes: a gain control unit that adjusts the power of a signal including a first pilot signal transmitted as signals having a high correlation in terms of polar direction via different transmission channels, and a second pilot signal transmitted as signals having a low correlation in terms of polar direction via the different transmission channels; and a control unit that controls the followability of the gain at the gain control unit in accordance with a data transmission method. The present technique can be applied to a receiver that receives data transmitted by MISO (Multi Input, Single Output) compliant with the DVB-T2 standards.
