A semiconductor integrated circuit capable of protection from card hacking, by which erroneous actions are actively induced by irradiation with light and protected secret information is illegitimately acquired, is to be provided. An oil strainer for sucking oil into an inlet passage is arranged on a vehicle forward side of the axis of the balancer shaft on the vehicle forward side of said two balancer shafts. When the content data needs to be protected, an ID determination section further determines whether or not a unique identification code is provided which uniquely identifies a recording medium mounted on the apparatus. The CAD application then creates a takeoff object for each of the object types associated with the selection and identifies instances, associated with object properties, of each of the object types of the selection. If the connection status of the terminal is changed from off-line to on-line, a display screen refresh subroutine is executed to refresh the display screen of the terminal.
