Abstract: In this puzzle game device, a three-dimensional game field 70 laterally extended around a tubular subject is provided. The 3D game field 70 is divided into display regions of vertically 12 lines by circumferentially 16 columns, and each display region is capable of displaying a panel. A player can move the panels displayed on the game field 70 with a cursor 71. The panels are varied in pattern, and when three or more panels of a pattern being vertically or laterally in line, those panels are eliminated. The 3D game field 70 has new panels continuously rising, therefore the player is required to unceasingly eliminate the panels. When the player fails to eliminate panels quick enough and the panels reach the top of the 3D game field 70, the game is over. By applying the 3D game field 70 as an alternative to a conventional 2D game field, the degree of freedom and the level of variety of a game are enhanced by the up-scaled game field.

Abstract: A puzzle game apparatus having an LCD. On the LCD is displayed a game field having square lattices arranged in a matrix. From an upper end of the game field is fallen a square slant-lined panel having two vertexes set as connection terminals. A game player is allowed to rotate or move the slant lined panel to connect a connection terminal of the panel to a connection terminal of an adjacent panel, thereby completing a bent lined figure continuing from a left end to a right end of the game field.

Abstract: In this video game device, a three-dimensional game field 70 laterally extended around a tubular subject is provided. The 3D game field 70 is divided into display regions of vertically 12 lines by circumferentially 16 columns, and each display region is capable of displaying a panel. A two-dimensional field table 80 is structured by spreading the 3D game field 70 across a 2D plane, and is provided with a plurality of entries each corresponding to one of the display regions of the 3D game field 70. To the entries of the 2D field table 80, pattern data of the panels is stored, and texture data corresponding thereto is placed on the corresponding display region of the 3D game field 70. Compared to a conventional game device applying a 2D game field, the degree of freedom and the level of variety of a game are enhanced by the substantially up-scaled display range of a-screen-basis game field, and game descriptions can be more creative with a 3D appearance.

Abstract: The induction charging apparatus has a power source unit and a device unit which can be detachably coupled to the power source unit. The power source unit has a first casing having one end opened, a primary coil provided in the first casing, an oscillator for supplying an alternating current to the primary coil to generate magnetic fluxes, and a depressible member movably provided and closing the open end of the first casing. The depressible member is movable between a lift position at which the magnetic fluxes are substantially located under the depressible member, and a depressed position at which portions of the magnetic fluxes are substantially located over the depressible member. The device unit has a second casing having one end detachable to the open end of the first casing, a secondary coil provided in the second casing and adjacent to the one end, and rechargeable battery provided in said second casing for receiving power from the secondary coil.

Abstract: A communication adapter which is used with a plurality of game sets for transmitting and receiving data related to the game states of the game sets. Each game set including a serial interface and a buffer memory for temporarily storing transmit/receive data. The adapter including: a housing; a connection terminal for each game set; data input, data output and clock output ports, a clock signal generator, format converter and transmit/receive storage means. The clock signal generating means applies the same clock signal used for data communication with the game sets to each clock output port so that data to be transmitted to each game set and data received from each game set is synchronized with the clock signal whereby reliable communication is obtained with two or more game sets without the use of modems.

Abstract: An X-axis counter (101) and a Y-axis counter (102) detect velocities of the movement of a mouse in X-axis and Y-axis directions, respectively. A comparator (103) detects which of the velocities of the movement of the mouse in the X-axis and Y-axis directions is higher. An X-axis displacement amount correction data ROM (106) and a Y-axis displacement amount correction data ROM (107) correct a detection result by the X-axis counter (101) and a detection result by the Y-axis counter (102) with the same correction rate based upon detection results by the comparator (103) to output displacements in the X-axis and Y-axis directions.
