  • Publication number: 20090046679
    Abstract: In a network configuration in which a mobility control node is placed in the network, a packet is forwarded from a communication partner to the mobility control node by a basic IP mobility protocol for supporting movement in a local network managed by the mobility control node, a movement of a mobile terminal device across local networks formed by mobility control nodes is achieved without adding a function to the mobile terminal device. A mobility control node to be provided to the mobile terminal device is identified by a trigger reporting a movement has been performed to the network from the mobile terminal device, and, in the case of HO across between mobility control nodes, network information before the movement is reported instead of network information to be originally reported. Thus, the mobile terminal device determines that the movement is in the same network and can continue communication without performing an address generation procedure.

  • Publication number: 20040037934
    Abstract: A method for preparing a cooked rice with stabilized quality on an industrial scale and cooked rice prepared according to the process, which has a moisture gradient formed between the outer layer and the inner layer of each rice grain and has no hard core in the rice grains when tested organoleptically. The method includes the steps of steaming raw rice having been subjected to a washing and soaking step to effect gelatinization of starch inside rice grains; cooling and individuating the resulting rice to remove moisture present on the surface of each rice grain; frying the resulting rice with an oil to form an oil film over the surface of each rice grain; and boiling the resulting rice together with seasonings and water. In the cooked rice, difference between the moisture content of the outer layer (to the depth of 0.5 mm from the surface) and that of the inner layer (portion deeper than 0.5 mm from the surface) of each rice grain is 2.5% to 5%, preferably 3% to 5%.

  • Publication number: 20010041595
    Abstract: A plurality of receiving sections are arranged within a single receiving unit. For instance, a first receiving unit 11a is equipped with two receiving sections 12a and 12c. For example, in the case that a failure happens to occur in the first receiving unit 11a, the base station is arranged in such a manner that another receiving section 12b belonging to a diversity receiving system of the same sector is located in a second receiving unit 11b operated under normal condition. As a result, even when a failure happens to occur in any one of arbitrary units, the receiving functions of the respective sectors can function as a single branch under normal condition, although the diversity gain is lowered.

  • Patent number: 5736647
    Abstract: A vortex flowmeter detector is attached to or detachable from a vortex generation body for measurement of flow rate. The vortex flowmeter detector comprises a cylindrical oscillation tube having a bottom and a vortex detection part which is fixed by a fixing flange of the oscillation tube, wherein the oscillation tube is detachably inserted into a hole which is open to the vortex generation body at one end thereof, and the oscillation tube is fixed by a flange. An alternate pressure caused by a Karman vortex is introduced from both sides of the vortex generation body into the hole so as to oscillate the oscillation tube. This oscillation is received by a spring plate by way of an element cover, and it is transmitted to piezoelectric elements which are stuck to two chamfers of an elastic base material.

  • Patent number: 5703913
    Abstract: A timing signal generator includes a demodulator for an input modulated signal to provide first and second baseband signals having a quadrature relation relative to each other. A converter is used to convert the first and second baseband signals into angle data representing a phase, and a calculator is used to calculate a difference between the phase represented by current angle data and the phase represented by previous angle data, preceding the current angle data by a 1-symbol interval. The calculator outputs data representative of the calculated phase difference. A further converter converts the calculator output data into a binary reference signal responsive to which of predetermined divided regions contains a point corresponding to the calculated difference data. Also included is a generator for generating a symbol timing signal in synchronism with the binary reference signal.

  • Patent number: 4627295
    Abstract: A vortex flow meter includes a bluff body which sheds a vortex train when a fluid flowing in a conduit moves therepast, the vortex train developing a delicate pressure variation in proportion to a flow rate of the fluid. The flow meter detects the flow rate by sensing the pressure variation and then converting it into an electric signal by means of a piezoelectric element or the like. A pressure sensor is detachably mounted in a pressure sensing chamber, which is defined in an internal space of the bluff body, and comprises a pressure receiving plate displaceable in response to the pressure variation, a sensor member such as a piezoelectric element for converting the displacement into an electric signal. The pressure receiving plate is arranged such that major part thereof is located in the conduit, while major part of the sensor member is located in a wall of the conduit and the outside thereof.

  • Patent number: 4625564
    Abstract: A vortex flow meter includes a vibration sensing element having a sensor responsive to an external vibration and a sensor responsive to a vortex train at vertically opposite ends thereof. The sensing element is fixed to a conduit fulcrumed at an intermediate portion thereof. A vortex shedding member is integrally and oscillatably mounted in a lower portion of the sensing element. The flow meter can be assembled merely by being positioned in the conduit and, due to an integral structure, it is effectively applicable even to small diameter conduits through which fluids flow at very small flow rates. In a path along which leads from a sensor responsive to pressure variations due to vortex trains are routed to a transducer box, vibration of the transducer box is prevented from reaching the sensor via the leads, thereby rendering the flow meter less susceptive to externally derived vibrations.

  • Patent number: 4526040
    Abstract: In a vortex flow meter for measuring a varying flow rate of a fluid through a conduit, an oscillation compensating apparatus is constructed to remove undesirable externally derived oscillation noise which is applied to the flow meter. An elongate vortex shedding member extends into the conduit through part of its wall. The shedding member forms a shedding portion inside the conduit and a compensating portion outside the conduit. The shedding portion carries a first oscillation sensor therewith and the compensating portion, a second oscillation sensor. The first sensor is sensitive to an oscillation component caused in the shedding portion by a vortex train shed in the conduit, and an externally derived oscillation noise component. The second sensor is sensitive to the noise component only. All these sensed components are combined to cancel the oscillation noise so that only the oscillation component in the shedding portion is picked up.

  • Patent number: 4511819
    Abstract: A piezoelectric sensor for measuring an external force is disclosed which is accommodated in a cassette through a sealing member and provided with a pair of electrodes which are respectively bonded to opposite sides of a piezoelectric element. A masking strip made of a highly insulative material covers the whole area of and end face of the piezoelectric element, which is exposed to the outside of the sensor, and a desired width of an end face of each of the electrodes adjacent to the end face of the piezoelectric element. This maintains a high resistance between the electrodes having the piezoelectric element therebetween and thereby promotes accurate measurement without being effected by changes in the resistance of the sealing member due to temperature variation. The sensor is effectively applicable to a vortex flow meter.
