20110148810 | TOUCH SCREEN DEVICE - Touch positions can be detected with a high accuracy. A receiver receives a charge-discharge current signal of a receiving electrode in response to a drive (pulse) signal applied to a transmission electrode, and outputs a level signal of each electrode intersection. The receiver includes an IV converter that converts the charge-discharge current signal to a voltage signal. A conversion characteristic of the IV converter is set such that phases of amplitude of the voltage signal corresponding to a leading edge and a trailing edge of a pulse wave of the drive signal substantially match each other, and phases of amplitude of the voltage signal corresponding to the trailing edge of the pulse wave and a leading edge of a succeeding pulse wave substantially match each other. | 06-23-2011 |
20110169756 | ELECTRONIC PEN SYSTEM - An electronic pen transmits pen information to a controller corresponding to detection of a touch condition, and thereafter turns ON a connecting switch that disconnects electrical connection between the tip portion and the grip portion of the pen that are provided in a state of being electrically disconnected from each other so as to cause a pen input acceptance state. The controller determines that position detection information is from the electronic pen when the position detection information is received from a position detecting device after the pen information is received from the electronic pen, while the controller determines that position detection information is from a finger when the position detection information is received from the position detecting device without receiving the pen information from the electronic pen. | 07-14-2011 |

20120069238 | IMAGE CAPTURING DEVICE - A rotation body having an optical member is stored in an optical capsule that is filled with a liquid that is an anti-freeze solution. A magnetic rotation driver rotates the rotation body by applying a magnetic force in a rotation direction to a first magnetizer provided to the rotation body, and heats the liquid. Specifically, the stator core that configures the magnetic rotation driver is formed so that a surface opposing the first magnetizer fits along a curved surface of an outer surface of the optical capsule. The opposing surface is applied with a silicon grease and then firmly attached to the optical capsule. Thus, the entire opposing surface of the stator core acts as a thermal conduction path to more efficiently heat the liquid, thereby making it possible to stably rotate the rotation body even in a cold environment. | 03-22-2012 |
