Abstract: A game apparatus provides gameplay concerning development of characters evolving through multiple evolution stages. Type information uniquely identifying the type and the evolution state of each character capable of being developed in the game apparatus is defined. The game apparatus includes a first acquisition unit acquiring information about a state of activity of a wearer; an update unit updating a first parameter and a second parameter concerning a developing character based on the information about the state of activity and the type information about the developing character; a display control unit causing a display unit to display the developing character in a display mode corresponding to the first and second parameters; an accumulation unit accumulating an evolution score concerning development of the developing character based on the first and second parameters; and a determination unit determining a target character of the developing character based on the evolution score.

A material for the mask layer made of a nonlinear optical material is a photochromic compound, for example, spiropyran, spirooxazine, azobenzene, fulgide, diarylethene, triarylmethane, indigo, etc.

Abstract: A magnetic bubble recording element including a substrate having a transfer channel, a first magnetic layer for carrying a magnetic bubble and being formed on the substrate within and outside of the transfer channel with a surface of the first magnetic layer within the transfer channel being offset from at least a portion of a surface of the first magnetic layer outside of the transfer channel, and a second magnetic layer for applying a bias magnetic field to the first magnetic layer being formed on the first magnetic layer within and outside of the transfer channel. The magnetic bubble contained in the first magnetic layer being transferred along the transfer channel by an external magnetic field.

Abstract: An optical recording medium is formed to include a resinous substrate, a laminate film including an inorganic dielectric layer and a recording layer, and a resinous protective film, respectively disposed on the substrate. The laminate film is formed to have a compression stress of 15-55 kg/mm.sup.2 so as to be in a dense film free from cracking or peeling. The resinous protective layer is formed to have a tensile stress of 2.5-5.5 kg/mm.sup.2 so as to compensate the compression stress in the laminate film, thus preventing warp and skew of the optical recording medium. The resinous protective film may preferably be formed from a photocurable composition comprising an increased amount of a polyacrylate compound providing a dense film and a urethane acrylate compound providing a flexibility.

Abstract: A toll road terminal machine having dual functions as a transit ticket issuing machine at an entrance gate and as a transit ticket verifying machine at an exit gate includes: a main conveyor section provided with a magnetic read/write head assembly for writing on and reading from a magnetic recording zone of a transit ticket and a printer for printing on a printing zone of the same transit ticket; the machine also includes a joining conveyor section for conveying either a transit ticket fed from a transit ticket hopper or a transit ticket inserted into an insertion port to the main conveyor section, and a separating conveyor section for conveying a transit ticket fed from said main conveyor section either to a stacker or to an ejection port.
