20160047932 | ELECTRIC NEAR-FIELD PROBE, CONTROL SYSTEM FOR SAME, AND PIEZOELECTRIC CRYSTAL DETECTOR - Provided is a compact and lightweight electric field probe which has a transmitting/receiving function whereby piezoelectric crystals can be excited through the application of an alternating current electric field thereto, and piezoelectric effect signals can be detected with sufficient sensitivity. Also provided are a control system for the same, and a piezoelectric crystal detector. The electric near-field probe is provided with a capacitor, in which the space between two metal plates that are positioned parallel to each other is filled by a conductor or air, and a series resonance circuit, which has a prescribed resonance frequency and is connected in series to an inverter that is formed by winding a conductive wire around a toroidal core. The electric near-field probe is configured such that: an electric near-field, which originates from the leakage electric field from the capacitor generated by the application of alternating current voltage to the series resonance circuit, is transmitted to the piezoelectric crystals, and the piezoelectric crystals are excited; and the piezoelectric effect signal, which is generated by the excited piezoelectric crystals, is received by the capacitor, and is detected by the series resonance circuit. The control system is for said electric near-field probe. | 02-18-2016 |

20110050759 | DISPLAY DEVICE AND SCANNING LINE DRIVING DEVICE - In a display device driven by multi-picture element driving, in order to realize narrowing of a frame, a gate driver provided in the display device includes buffers. Storage capacitor driving signals are inputted in the buffers. In at least one embodiment, once the storage capacitor driving signals are inputted, the buffers shape waveforms of the storage capacitor driving signals, and outputs the storage capacitor driving signals thus shaped to storage capacitor wires via terminals “CSVtypeA | 03-03-2011 |

20150072793 | SERVER SYSTEM AND METHOD FOR CONTROLLING COMPUTER SYSTEM - A server system and the like allow the users who play asynchronous games to perceive each other's presence to prompt the users to communicate with each other and feel a sense of solidarity. When the progress of a first game played by one player has changed to be advantageous to the player due to the use of an AP recovery item or the like, a parameter in the first game is incremented (e.g., action points AP are recovered). A parameter in a second game played by a friend user of the player is also incremented (e.g., the action points AP are recovered) through an extension control process. An activation notification W12 that notifies to that effect is displayed on a user terminal of the player who plays the first game. | 03-12-2015 |
