20120106072 | DRIVING APPARATUS FOR SENSORLESS FAN MOTOR - A BEMF detection circuit generates a rotation detection signal indicating a comparison result between electromotive force voltages V | 05-03-2012 |
20120207619 | FAN MOTOR DRIVING DEVICE AND COOLING DEVICE USING THE SAME - The present invention is provided to remove dust that adhered to a cooling fan. A plurality of comparators are disposed for each of a plurality of coils, respectively, and generates a back electromotive force sensing signal denoting a comparison result by comparing a back electromotive force appearing at one end of each corresponding coil with a neutral-point voltage of the coils. A driving signal synthesis circuit generates a driving control signal used to enable the fan motor to proceed the following actions: (i) enabling the fan motor to rotate toward the opposite direction as a normal operation within a specific reverse rotation period after a driving of the fan motor is started, (ii) applying a brake to the fan motor within a braking period, and (iii) enabling the fan motor to rotate toward a direction of normal operation in a normal driving period. A driving circuit drives the fan motor. | 08-16-2012 |
20120268047 | FAN MOTOR DRIVING DEVICE, AND COOLING DEVICE AND ELECTRONIC MACHINE USING THE SAME - The objective of the present invention is to miniaturize a driving circuit of a fan motor. The present invention provides a driving device for driving a fan motor as a three-phase brushless DC motor. An inbuilt Hall component is disposed adjacent to the fan motor and generates a pair of Hall signals corresponding to a rotor position of the fan motor. An internal power source supplies a bias signal to the inbuilt Hall component. A Hall signal processing portion cancels a shift of the pair of Hall signals and amplifies the Hall signal. A driving processing circuit drives the fan motor according to an output signal of the Hall signal processing portion. The driving device is integrated on a semiconductor substrate. | 10-25-2012 |
20140028236 | DRIVING APPARATUS FOR FAN MOTER - A digital filter is configured to convert, into a digital value, the duty ratio of a control signal subjected to pulse width modulation according to a target toque to be set for a fan motor to be driven. A sampling circuit is configured to perform sampling of the output value of the digital filter at a sampling timing that is asynchronous with respect to the cycle of the control signal, so as to generate a torque instruction value. A driving circuit is configured to drive the fan motor according to the torque instruction value thus generated. | 01-30-2014 |

20120262447 | STORAGE MEDIUM, INFORMATION PROCESSING APPARATUS, INFORMATION PROCESSING METHOD AND INFORMATION PROCESSING SYSTEM - A computer-readable storage medium having stored therein an information processing program to be executed by a computer is provided. The information processing program causes the computer to function as: preferential display object placing means for placing a preferential display object in an imaging range of a virtual stereo camera in a virtual three-dimensional space; stereoscopically visible image rendering means for taking the virtual three-dimensional space using the virtual stereo camera, and rendering a stereoscopically visible image of the virtual three-dimensional space; and display control means for causing the display apparatus to display the stereoscopically visible image rendered by the stereoscopically visible image rendering means. The stereoscopically visible image rendering means renders the preferential display object in preference to a predetermined object in front of the preferential display object, such that a portion of the preferential display object being overlapped by the predetermined object is translucent. | 10-18-2012 |
20130217452 | GAME SYSTEM, GAME CONTROL METHOD, GAME DEVICE, AND COMPUTER-READABLE STORAGE MEDIUM - An exemplary embodiment sets the game background image with surface objects (bricks, coins, item closed box baffles, monsters, and the like) arranged therein in the middle of the tennis court within a virtual space for executing a tennis game containing the motion of hitting the tennis ball according to an operation by the player, and scrolls the surface objects arranged in the game background image. Then, there is provided an effect corresponding to the type of the surface object (benefit object, the hit map switching object, scoring object, or the like) arranged in a position of the game background image, where the tennis ball shot in response to a player-operation has reached. | 08-22-2013 |
20140171193 | GAME SYSTEM, COMPUTER-READABLE NON-TRANSITORY STORAGE MEDIUM HAVING STORED THEREIN GAME PROGRAM, GAME PROCESS CONTROL METHOD, AND GAME APPARATUS - A first input image is displayed in a predetermined area on a touch screen, and a second input image in which images in a plurality of areas are drawn so as to be distinguishable from each other by a player is displayed in accordance with a touch input on the first input image instead of the first input image. It is determined whether a touch input has been performed on any of the images in the plurality of areas of the second input image, and a process is performed in accordance with the touched image in the area. Then, a predetermined object is controlled on the basis of a timing of the touch input on the second input image and a result of the process corresponding to the touched image in area. | 06-19-2014 |
20150319266 | COMPUTER-READABLE NON-TRANSITORY STORAGE MEDIUM HAVING STORED THEREIN INFORMATION PROCESSING PROGRAM, INFORMATION PROCESSING APPARATUS, INFORMATION PROCESSING SYSTEM, AND INFORMATION PROCESSING METHOD - After presentation target information for presenting information of a predetermined content to a user has been newly received from a predetermined server, a first notification that urges the user to check the newly-arrived presentation target information is displayed. Thereafter, while the presentation target information has not yet been checked, a second notification that urges the user to check the unchecked presentation target information is displayed periodically or according to a predetermined time schedule. The presentation target information is displayed when an operation to check the presentation target information is performed to the first notification or the second notification has been performed. | 11-05-2015 |
20160101354 | INFORMATION PROCESSING SYSTEM, INFORMATION PROCESSING APPARATUS, RECORDING MEDIUM AND INFORMATION PROCESSING METHOD - An example system includes a server and multiple information processing apparatuses. The server includes a competition request acceptance unit accepting a competition request from the information processing apparatus, and an opponent decision unit deciding an opponent of a user concerning the request accepted by the competition request acceptance unit. The information processing system includes a history storage unit storing competition history information for a user in a tournament, an exchange processing unit performing processing of exchanging at least a part of the competition history information between competing users, based on the decision made by the opponent decision unit, and a competition processing unit performing processing concerning a competition between the users. The opponent decision unit decides an opponent based on at least a part of competition history information stored in the history storage unit. | 04-14-2016 |
