Publication number: 20090085805Abstract: A wide-angle null-fill antenna with no null in the depression angle range, an omni antenna using the same, and radio communication equipment. A null-fill antenna comprises a first antenna array including antenna elements arranged with a prescribed point as the center, and a second antenna array having amplitude characteristics substantially equal to those of the antenna elements forming the first antenna array. The first antenna array is excited so that the excitation amplitude distribution is to have symmetry with respect to the prescribed point, while the excitation phase distribution is to have point symmetry with respect to the prescribed point. The phase center of the first antenna array is substantially coincident with that of the second antenna array.Type: ApplicationFiled: December 2, 2008Publication date: April 2, 2009Applicant: NEC CORPORAITONInventor: Norihiko Oomuro

Patent number: 6639275Abstract: A semiconductor device improves the gate withstand voltage of vertical MOSFETs and raises their operation speed. The gate electrode is formed in the trench of the second semiconductor layer. The interlayer dielectric layer has the contact hole that exposes the connection portion of the gate electrode, where the connection portion is located in the trench. The conductive plug is filled in the contact hole of the interlayer dielectric layer in such a way as to contact the connection portion of the gate electrode. The wiring layer is formed on the interlayer dielectric layer in such a way as to contact the plug, resulting in the wiring layer electrically connected to the connection portion by way of the plug. There is no need to form a connection portion for the gate electrode outside of the trench, which means that the gate dielectric does not include a weak or thinner portion where dielectric breakdown is likely to occur.Type: GrantFiled: June 10, 2002Date of Patent: October 28, 2003Assignee: NEC CorporaitonInventor: Hitoshi Ninomiya

Patent number: 6042112Abstract: A guide plate is arranged in spaced parallel relation with a recording head. A pinch roller and a paper conveyer roller are arranged upstream of the guide plate with respect to a paper feeding direction. The pinch roller takes an entrance position to provide a state wherein the rollers most easily catch paper sheet. After the rollers have caught the paper sheet, the pinch roller is displaced to take an exit position to provide a state wherein the roller deflect the paper sheet towards the guide plate.Type: GrantFiled: November 15, 1997Date of Patent: March 28, 2000Assignee: NEC CorporaitonInventor: Naoyuki Izumi

Patent number: 6040973Abstract: A field emission cold cathode device is driven to make an emission current constant without limiting the available choice of materials for a gate electrode. A positive voltage with reference to OV is applied from a gate power supply to gate electrode of the field emission cold cathode device to enable emitter disposed respectively near the gate electrode to emit electrons. After the positive voltage with reference to OV is applied, a negative voltage with reference to OV is applied from the gate power supply to the gate electrode at a predetermined time.Type: GrantFiled: January 28, 1998Date of Patent: March 21, 2000Assignee: NEC CorporaitonInventors: Akihiko Okamoto, Fuminori Ito

Patent number: 5825508Abstract: In an image transmission apparatus, image data frames are sequentially received from the source terminal through a connection line at a first transmission rate while checking whether an error occurs in each of the image data frames. When the error occurs in consecutive image data frames whose run length is not smaller than a predetermined value, the transmission rate is changed to a second transmission rate which is smaller than the first transmission rate based on the run length of the consecutive image data frames and the predetermined value. At the second transmission rate, image data frames in which the error occurred are sequentially received from the source terminal through the connection line.Type: GrantFiled: August 20, 1996Date of Patent: October 20, 1998Assignee: NEC CorporaitonInventor: Hirokazu Mukai

Patent number: 5542061Abstract: In order to effectively accelerate issue of a RAM read instruction which is to access the same memory block as a preceding RAM write instruction, when the RAM write instruction is issued, a counter initiates counting-up of a value indicative a predetermined time duration. When the counter counts up the value, the RAM read instruction is allowed to be issued at appropriate timing. A time duration for which the RAM read instruction is prohibited to be issued, is much shorter than a time duration which expires when the RAM write instruction is completely finished. Thus, the RAM read instruction issue is not required to wait for the completion of execution of the RAM write instruction as in a known technique.Type: GrantFiled: May 8, 1995Date of Patent: July 30, 1996Assignee: NEC CorporaitonInventor: Makoto Omata
