Abstract: A valve system includes: a cam shaft including a shaft section and a plurality of cam element sections; and a plurality of operation members that moves the cam element sections in an axial direction. The plurality of operation members include a common operation member that is provided in common between end face cams opposed to each other of the cam element sections of two cylinders disposed adjacent to each other and continuous in ignition order and that engages with the respective end face cams when both the cam element sections are close to each other, and individual operation members that are individually provided for end face cams opposed to each other of the cam element sections of two cylinders disposed adjacent to each other and discontinuous in ignition order and end face cams located at opposite ends of a cylinder row and that engage with the respective end face cams.

Abstract: A content delivery system, a method thereof, and a content reproducing device are provided. The content reproducing device comprises a content separator, an insufficient content storing section, and a server. The content separator separates or divides content into an insufficient content and a complementary content. The insufficient content storing section stores the insufficient content sent (outputted) from the content separator. The server includes a storing means for storing the complementary content sent from the content separator, and sends the complementary content to the content reproducing device via a network. The content reproducing device acquires the complementary content from the server and the insufficient content from the insufficient content storing section. Thereafter, the content reproducing device reproduces the content using the insufficient content and the complementary content.
