Abstract: There is provided a small-sized vibration generator that resonates at two different frequencies. A movable base is housed inside a case. The movable base has an installation plate, and supporting plates bent at right angles from both ends of the installation plate. A first elastically deformable portion is formed integrally with the installation plate, and a weight body is supported by the first elastically deformable portion. In the movable base, a second elastically deformable portion is provided between the installation plate and the supporting plates, and the supporting plates are fixed to supporting end plates of the case. The bending elastic modulus of the second elastically deformable portion is higher than the bending elastic modulus of the first elastically deformable portion, and resonates at two natural frequencies when a driving force is applied to the weight body by a magnetically-driven portion.

Abstract: When receiving a marker cell indicative of a timing of switching between current use and reserve use, system switching control section 280-1 in first transmission path interface section 270-1 that is for current use in the initial state notifies system switching control section 280-2 for reserve use of the contents of reading order table and reading pointer. Until marker cells are detected in buffers for all quality classes after receiving a marker cell, read section 276-1 for current use continues to read cells based on the reading order table and reading pointer, while read section 276-2 for reserve use abandons cells based on the reading order table and reading pointer notified from system switching control section 280-2. Then, when marker cells are detected in the buffers for all the quality classes in the system for current use, switching is performed from the current use to reserve use.

Abstract: Node synchronization slave apparatus 131 detects a timewise variation in the time of arrival of a data frame transmitted from node synchronization master apparatus 111 via cable transmission path 152, and based on the variation in the time of arrival, calculates a predicted value of the time of arrival of a data frame to be received next and thereafter. When the predicted value of the time of arrival indicates late arrival of a data frame and the arrival of the data frame is out of a reception window, the apparatus 131 notifies node synchronization master apparatus 111 of the predicted value of the time of arrival. According to the notification, node synchronization master apparatus 111 advances a transmission timing of a data frame than a reference value in order for the data frame to be received within the reception window.
