| 20120001719 | DUST CORE AND METHOD FOR MANUFACTURING THE SAME - Provided is a dust core and a method for manufacturing a thereof, having an effect that the soft magnetic powder is prevented from sintering and bonding together upon heating, the hysteresis loss can be effectively reduced, and the DC B-H characteristics is excellent. In a first mixing process, a soft magnetic powder composed mainly of iron and an inorganic insulating powder of 0.4 wt %-1.5 wt % are mixed by a mixer. A mixture obtained in the first mixing process is heated in a non-oxidizing atmosphere at 1000° C. or more and below a sintering temperature of the soft magnetic powder. In a binder addition process, a silane coupling agent of 0.1-0.5 wt % is added. A binder, e.g. a silicone resin of 0.5-2.0 wt % is added to the soft magnetic alloy powder to which the inorganic insulating powder is attached by the silane coupling agent, and the soft magnetic alloy powders are bonded to each other so as to be granulated. Then, the mixture is added with a lubricant resin and compression-molded so as to form a green compact. In an annealing process, the mold is annealed in a non-oxidizing atmosphere. | 01-05-2012 |

| 20080234843 | Projector, projection display system, and corresponding method and recording medium - A projector that projects images includes a projection display module by which the projector projects the images, a network interface by which the projector can communicate with a network, and a web server module coupled to the network interface and to the projection display module. The web server module, in response to a request to provide a working status of the projection display module received through the network interface from a client over the network, sends working status information representing the working status through the network interface to the client over the network. The web server module also, in response to control information received through the network interface from the client over the network in response to the sent working status information, controls the working status by sending a control signal to the projection display module based on the control information. | 09-25-2008 |
| 20100309210 | Projector, projection display system, and corresponding method and recording medium - In response to a requirement of transferring a file from a personal computer PC to a projector | 12-09-2010 |
| 20110209060 | METHOD AND ADJUSTING DEVICE FOR PROJECTION-TYPE DISPLAY - An image display device including an image input means to which image signals are input, an image display means for forming an optical image based on the image signals, and a device adjusting means for adjusting internal conditions of the device is provided with an adjusting operation support means for supporting an operation of the device adjusting means. Because the adjusting operation support means is provided, a user may easily adjust the image display device while confirming adjusting operation support information displayed by the adjusting operation support means. | 08-25-2011 |
| 20110210977 | Projector, projection display system, and corresponding method and recording medium - A method includes sending image related working status information representing image-related working status of a projector that projects images, to a client over a network in response to a request to provide the image-related working status of the projector. The image-related working status is related to display characteristic of the projected image. The method includes controlling the image-related working status of the projector based on the control information received from the client over the network in response to the sent image-related working status information. The image-related working status information is sent to the client with screen information from which the client can display a user interface that includes the image-related working status information. | 09-01-2011 |

| 20100201442 | DISTORTION COMPENSATION DEVICE FOR USE IN HIGH-FREQUENCY POWER AMPLIFIER - A non-linear distortion signal contained in output signal components from a high-frequency power amplifier is detected, while a non-linear distortion signal is generated from a high-frequency signal to be amplified. Correlation between this non-linear distortion signal and the detected non-linear distortion signal is determined, and a control variable is calculated based on the signal thus obtained. The obtained control variable is multiplied by the generated non-linear distortion signal to generate a distortion compensation signal, which is added to the signal to be amplified. This provides a distortion compensation device capable of automatically maintaining optimum distortion compensation characteristics and rapidly achieving desirable distortion compensation. | 08-12-2010 |
