  • Patent number: 6942060
    Abstract: A portable information terminal device has a plurality of casings providing a front surface and a rear surface, respectively. The casings have walls defining spaces in which speakers are housed and thicker than walls thereof that define a space in which a component including an internal circuit is housed. The walls defining the spaces in which speakers are housed are prevented from causing resonance due to vibrations of the speakers. The walls that define the space in which the component including the internal circuit is housed may be of a minimum thickness required irrespective of resonance caused by vibrations of the speakers. With the above arrangement, the portable information terminal device is small in size and weight.

  • Patent number: 6944535
    Abstract: 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.

  • Patent number: 6944246
    Abstract: 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.

  • Patent number: 6943128
    Abstract: 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.

  • Patent number: 6939069
    Abstract: A composite writing utensil comprising a front barrel and a rear barrel, a cam body provided within the barrel unrotatable with respect to the rear barrel, and a slider unrotatable with respect to the front barrel and coupled to each of a plurality of writing shafts. The cam body includes a V-shaped cam projection projecting forward, a cam surface, and a restraining portion. The slider comprises a V-shaped cam projecting rearward, and a slidably-contacted surface extending along the cam that is urged against the cam surface. A relative rotation between front and rear barrels causes the slidably-contacted surface of the cam to slidably contact the cam surface and one of the cams to be restrained by the restraining portion, thus a point of the writing shaft coupled to the slider provided with the cam selectively projects from the point aperture of the barrel.

  • Patent number: 6941354
    Abstract: 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.

  • Patent number: 6940839
    Abstract: 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.
