20080272855 | LAMINATE TYPE BAND PASS FILTER AND DIPLEXER USING THE SAME - It is possible to generate an additionally attenuation pole in a laminate type band pass filter without adding an attenuation circuit and improve the attenuation characteristics of the laminate type band pass filter by independently controlling the frequencies of the attenuation poles. A diplexer is realized by using at least such a filter. The laminate type band pass filter includes a plurality of first resonators adapted to resonate in a predetermined pass band and arranged in a laminate, the first resonators being mutually electromagnetic field coupled, each of the first resonators having a first inductor conductor, a second inductor conductor and a conductor to be capacitive-coupled to a grounding conductor, the second inductor conductor and the conductor to be capacitive-coupled to the grounding conductor forming a second serial resonator in each of the first resonators, the notch frequency of the second serial resonator being set in a frequency band higher than the resonance frequency band of the first resonator. | 11-06-2008 |

20110177347 | GLASS ROLL - Provided is a glass roll utilizing a flanged roll core, and reliably inhibiting a glass film from breaking from an end portion in a width direction thereof as an origin of breakage. A glass roll ( | 07-21-2011 |
20110200812 | GLASS ROLL AND PROCESS FOR PRODUCING GLASS ROLL - Provided is a glass roll formed by winding a glass film into a roll, in which a minimum winding radius of the glass film is optimized. Thus, the glass film is reliably prevented from breaking due to static fatigue, and is able to be stored for long periods. A glass roll ( | 08-18-2011 |
20140319001 | GLASS ROLL WITH A SEPARABLE PROTECTIVE SHEET - A glass roll includes a glass film formed by a downdraw method. The glass film is wound into a roll using a winding roller in a state in which front and back glass surfaces of the glass film formed in the forming operation are exposed, and during the winding operation, the glass film is superposed on a separable protective sheet. The protective sheet extends beyond both sides in a width direction of the glass film. The protective sheet can further be wound on an outer peripheral surface of the glass film by winding only the protective sheet from a trailing end of the glass film in a winding direction of the glass film. | 10-30-2014 |
