Patent number: 6943128Abstract: To lower the electrical resistance of a p-type semiconductor or the operation voltage of a light-emitting/light-receiving semiconductor device. An ion-plasma-type electron-beam irradiation apparatus 100 generates wide-area-radiation electron beams. The thus-generated electron beams are radiated to the outside through a thin metallic plate 108 formed on the outer surface of a beam extraction window 107. A p-type semiconductor is disposed below the beam extraction window 107 such that the p-type semiconductor is disposed about 20 mm away from the electron extraction window so as to be almost parallel to the metallic plate 108. When the surface of the p-type semiconductor is irradiated with electron beams by use of this apparatus, the electrical resistance of the p-type semiconductor can be effectively lowered within a short period of time; i.e., within about three minutes, which is considerably shorter than the time required in the case where a conventional electron-beam irradiation apparatus is employed.Type: GrantFiled: August 22, 2001Date of Patent: September 13, 2005Assignee: Toyoda Gosei Co., Ltd.Inventors: Toshiaki Chiyo, Naoki Shibata

Patent number: 6943379Abstract: In a light emitting diode, a blue light emitting element is mounted on a base having a cup through a phosphor-containing mount so that the light emitting element is located within the cup and is mounted on the bottom of the cup through the phosphor-containing mount. The light emitting diode includes a light emitting element and a p electrode. By virtue of the above construction, blue light emitted from the light emitting element can be reflected from the lower surface of the p electrode without being radiated directly from the upper surface of the light emitting element to the outside of the light emitting diode. As a result, the blue light emitted from the light emitting element can be efficiently mixed with yellow light given off from the phosphor in the phosphor-containing mount to provide white light which is radiated to the outside of the light emitting diode with high efficiency.Type: GrantFiled: March 24, 2003Date of Patent: September 13, 2005Assignee: Toyoda Gosei Co., Ltd.Inventors: Yoshinobu Suehiro, Hitomi Kawano, Tatsuya Takashima, Yuji Takahashi, Atsuo Hirano

Patent number: 6944246Abstract: An IC card is set to an RF mode by default when drive electric power starts being applied to the IC card. When both a clock signal and a reset signal are applied to respective connection terminals, the IC card switches to a terminal mode. The clock signal and the reset signal that are applied to the respective connection terminals can be detected without the need for an analog circuit such as a comparator. The IC card can be switched between the terminal mode in which only input signals applied to the connection terminals are effective and the RF mode in which only an input signal applied to a radio antenna is reliably effective, with only a digital circuit.Type: GrantFiled: August 8, 2000Date of Patent: September 13, 2005Assignee: NEC Electronics CorporationInventor: Hisanori Senba

Patent number: 6944535Abstract: A map display apparatus and a map display method facilitate detection of the relationship between a destination position or a current position and the surrounding area, even when a detailed map is to be displayed on a narrow display area. A map display terminal displays a particular position, such as the destination position or the current position, on a map. The current position might be derived on the basis of position information from a Global positioning System. An initial display can be a wide area map having smaller scale than a detailed map and centered destination position or the current position. More detailed maps centered at that position are displayed in stages.Type: GrantFiled: June 30, 2003Date of Patent: September 13, 2005Assignee: NEC CorporationInventor: Shinichiro Iwata

Patent number: 6941528Abstract: The invention provides a method and structure for optimizing placement of redundant vias within an integrated circuit design. The invention first locates target vias by determining which vias do not have a redundant via. Then, the invention draws marker shapes on or adjacent to the target vias. The marker shapes are only drawn in a horizontal or vertical direction from each of the target vias. The invention simultaneously expands all of the marker shapes in the first direction to a predetermined length or until the marker shapes reach the limits of a ground rule. During the expanding, different marker shapes will be expanded to different lengths. The invention determines which of the marker shapes were expanded sufficiently to form a valid redundant via to produce a first set of potential redundant vias and the invention eliminates marker shapes that could not be expanded sufficiently to form a valid redundant via.Type: GrantFiled: August 28, 2003Date of Patent: September 6, 2005Assignee: International Business Machines CorporationInventors: Robert J. Allen, Jason D. Hibbeler, Gustavo E. Tellez

Patent number: 6940839Abstract: The transmit power of a CDMA downlink channel is controlled from a base station by receiving a command signal from a mobile station requesting it to decrease the transmit power of the downlink channel. In response, the base station decreases the transmit power if a hypothetically decremented value of the transmit power is higher than a nominal lower limit of its power control range, and further decreases the transmit power if the downlink channel still has a quality higher than a specified value at the mobile station even when the hypothetically decremented value is lower than the nominal lower limit. The base station sets the transmit power equal to the nominal lower limit if the hypothetically decremented value is lower than the nominal lower limit and the downlink channel still has a quality higher than the specified value at the mobile station.Type: GrantFiled: February 6, 2001Date of Patent: September 6, 2005Assignee: NEC CorporationInventor: Yukie Miyamoto

Patent number: 6941354Abstract: There is provided a mobile terminal capable of properly selecting a communication network according to a kind of data targeted for sending and receiving when data is sent and received using a network. A mobile terminal 201 makes access to a WWW server 223 to acquire contents, and uses a packet communication gateway 225 to first acquire HTML data (main data) of the corresponding contents at the time of display. A tag for referring to various files (accompanying data) such as JPEG constructing the contents is embedded in this HTML data. Therefore, the mobile terminal 201 requests sizes of these files to the WWW server 223 by packet communication, and determines whether these files are acquired by packet communication or by line switching from the acquired file size. If these files are acquired by the line switching, the files are acquired from the WWW server 223 by using a line switching gateway 226 and making connection to an Internet network 222 through a public network 228, an Internet provider 229.Type: GrantFiled: May 1, 2001Date of Patent: September 6, 2005Assignee: NEC CorporationInventor: Satoshi Odamura
