Patent number: 8550906Abstract: The game machine and game program of the present invention display, at the start of a game, multiple static symbols by constantly changing to various types of symbols including the wild symbol. The game machine then executes a static display by displaying such changing symbols statically again in each display area and recognizes the arrangements of each static symbol. Then, the game machine visually displays the arrangement of the symbols by which multiple wins are established or the win line related to such arrangements of the symbols, when the pre-determined combinations of symbols, in which at least one wild symbol is included, are arranged so that multiple wins are established. The game machine and game program according to the present invention increases the player's interest and arouses the player's anticipation.Type: GrantFiled: September 22, 2003Date of Patent: October 8, 2013Assignee: Konami Gaming IncorporatedInventors: Satoshi Suda, Katsumi Takahashi, Takaaki Inoue, Takayuki Suzuki

Patent number: 8185006Abstract: A magnetic material detecting device, in which a concentration of magnetic material can be correctly detected, even when the magnetic material with unevenness in its density distribution flows. A magnetic field generating device is arranged in a two-component developer composed of magnetic carrier and non-magnetic toner and generates a magnetic field. A signal output device is arranged in the developer and outputs a signal depending on a magnetic permeability of the developer due to the magnetic field generated by the magnetic field generating device. An agitating unit agitates the developer and makes the developer flow between the magnetic field generating device and the signal output device.

Publication number: 20120045234Abstract: No registration pattern can be formed with a reference density due to environmental changes. In such a case, any registration cannot be formed until an image forming apparatus is controlled to be able to form a registration pattern with the reference density. To solve this problem, a CPU included in the image forming apparatus controls pattern forming conditions so that registration patterns of respective colors can match one another in density lower than the reference density. The CPU controls each image forming unit to form a registration pattern based on the controlled pattern forming conditions.Type: ApplicationFiled: August 15, 2011Publication date: February 23, 2012Applicant: CANON KABUSHIKI KAISHAInventors: Shinya Suzuki, Katsumi Takahashi
