Publication number: 20050233753Abstract: When a cell load becomes higher than a call setup threshold value for a first channel (CS channel), a second channel (PS channel) is changed into a channel having a low transmission rate. Consequently, the cell load is reduced and no cell loss occurs in the first channel. Therefore, the call loss rate of a first communication service is lowered. Simultaneously, a handover threshold value is higher than the call setup threshold value for the first channel so that a failure rate of handover is lowered.Type: ApplicationFiled: April 6, 2005Publication date: October 20, 2005Inventors: Kojiro Hamabe, Kenji Kawaguchi

Publication number: 20040066774Abstract: In a mobile communication system, when a connection necessary to provide a service supporting high-speed data communication referred to as an MBMS is configured on an Iu interface, contention with the other packet communication service is eliminated. As a logical connection established between an SGSN and a Radio Network Controller in a Core Network 10, a PS (packet switching processing) functional connection for an existing packet communication service and a connection for a new MBMS service offering high-speed data communication are provided separately and independently from each other. This eliminates the contention between different types of services of the PS service and the MBMS service to thereby enable executing processings of such different types of services without being conscious of mutual processings. In addition, release processing of the connection may be executed independently to each service, thereby eliminating processing complexity in the SGSN.Type: ApplicationFiled: October 6, 2003Publication date: April 8, 2004Applicant: NEC CorporationInventors: Kenji Kawaguchi, Masahiko Kojima, Toshiyuki Tamura

Patent number: 6714532Abstract: A network connecting device 100 comprises a LAN I/F 130 for performing communications with a LAN, a N-ISDN I/F 170 for performing a connectionless transmission, and a ATM I/F 160 for performing a connection-oriented transmission. A plurality of networks having different transfer systems are separately used, and communication channels are switched as occasion demands. A connection table section 200 holds correspondence among individual communication channels. A channel setting control program section 500 allocates a communication channel for new communication data. A kicking-out program section 1300 makes a communication channel used for low-priority communication data available for high-priority communication data. A recovery program section 700 reallocates a communication channel for communication data that has changed a communication channel after completion of high-priority communications.Type: GrantFiled: March 1, 2000Date of Patent: March 30, 2004Assignee: Hitachi, Ltd.Inventor: Kenji Kawaguchi

Patent number: 6334356Abstract: This invention relates to a method for deciding an amount of correction factor for the viscosity of a fluid test sample needed for correcting a calculation or measurement of the density based on the viscosity. The method for deciding the viscosity of the fluid test sample, during a density measurement performed by an oscillating densitometer where there is a peak point on the viscosity-attenuation constant characteristic of the test sample at the specific order oscillation, is to decide whether the attenuation constant of the viscosity-attenuation constant characteristic of the test sample at the other specific order oscillation is larger or smaller than that corresponding to the peak point, to decide according to said decision whether the viscosity detected by the attenuation constant obtained at the specific order oscillation belongs to either side larger or smaller than the peak point, and then to decide upon and determine the viscosity of the test sample according to the above two decisions.Type: GrantFiled: October 15, 1999Date of Patent: January 1, 2002Assignee: Kyoto Electronics Manufacturing Company, LimitedInventors: Toshiro Kita, Kenji Kawaguchi, Toshiyuki Shimizu

Patent number: 5793189Abstract: To provide an electric vehicle in which a low voltage power, obtained by conversion from a high voltage power of a main battery by a DC--DC convertor, is supplied to an operation control unit and electric equipment loads such as a lamp and is also used to charge a low voltage secondary battery, in which the main battery and the low voltage secondary battery are prevented from being over-discharged even when a main switch is left in the on-state. A low voltage power VR outputted from a DC--DC convertor is supplied to an exciting winding of a relay and is also supplied to a low voltage secondary battery through a diode. The low voltage power VR is supplied to low voltage loads through a contact of the relay. The DC--DC convertor is so constructed that the output of the low voltage power therefrom is stopped when the output voltage of the DC--DC convertor is reduced to a value less than a specified range due to the reduction in the battery capacity of the main battery.Type: GrantFiled: June 14, 1996Date of Patent: August 11, 1998Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Kenji Kawaguchi, Masayuki Toriyama, Hiroshi Tanaka, Masahide Yokoo
