Provided are an optical disc discrimination method, an optical disc device and an integrated circuit that enable to accurately discriminate the type of an optical disc. The optical disc discrimination method comprises a first seeking step (S3) of performing a seek operation to a predetermined reference address in a user data area; a second seeking step (S5) of performing a seek operation from the reference address sought in the first seeking step (S3) to a predetermined target address in a physical information area, an address reading step (S7) of reading a current address at a position sought in the second seeking step (S5), and an optical disc type determination step (S8 through S10) of determining the type of the optical disc loaded in the optical disc device, based on the current address read in the address reading step (S7).

摘要:
An osteosynthetic pin characterized in that the pin is formed substantially of a poly-L-lactic acid having a molecular weight of at least about 70,000, and is formed by axially drawing about 2 to about 10 times at an elevated temperature of about 70.degree. to about 120.degree. C.
摘要:
A game apparatus enabling a person to learn the standard orders of development in or to solve a problem of the game of Go, shogi (Japanese chess), chess or the like. In the case of learning the standard orders of development in the game, this game apparatus detects and displays the move of a game piece, and in the case of the game problem, the game apparatus counts the number of error moves of the game piece and does not display the correct move of the game piece until the counted number of error moves of the game piece is greater than a predetermined value, and then displays the correct move of the game piece.
摘要:
A game apparatus for enabling players present at remote places from each other to easily play the game through a connected common communication network like a telephone line. The game apparatus has functions for detecting and displaying the moved arrangement of a game piece, for transmitting and receiving the detected signals via the communication network, and for collating the reproductive motion of the one player, performed by watching the displayed moved arrangement of a game piece, with the intended motion carried out by the other player.
