Abstract:
PROBLEM TO BE SOLVED: To provide a telecommunication terminal having a configuration capable of easily finding out a location for a lost exchangeable unit of the terminal and inhibiting the illegal use of the unit. SOLUTION: The telecommunication terminal comprises a first unit 1 and a second unit 2 which can be detached and attached freely. The first unit 1 comprises a first communication means 12 for sending out a first ID 11 given beforehand to the second unit 2. The second unit 2 comprises a second communication means 22 for requesting the first unit 1 to transmit the first ID 11 in predetermined timing and transmitting the first ID 11 along with a second ID 21 defined beforehand to a server 5. The server 5 records a set of the first and the second IDs, responds to an inquiry from a user, and carries out required actions such as the stop of use. COPYRIGHT: (C)2008,JPO&INPIT

PROBLEM TO BE SOLVED: To eliminate a peak and a dip in a frequency characteristic caused in higher order vibration modes of the diaphragm of a speaker. SOLUTION: An outer circumferential part of the circular diaphragm 1 is fixed to a frame 2. A disk shaped piezoelectric ceramic element 3 is adhered to in the center of a backside of the diaphragm 1. An outer circumferential end of a sub diaphragm 4 of a doughnut shape (ring disk) having a circular hole 6 in the center is concentrically joined to the center of the diaphragm 1 by a joining part 5 on a side opposite to the side of the diaphragm 1 to which the piezoelectric ceramic element 3 is adhered. Particularly the outer circumferential part of the circular sub diaphragm 4 is joined by a joining part 5 along a loop part between nodes in the vibration mode (secondary resonance mode) wherein two vibration nodes are concentrically formed to the center of the circular diaphragm 1 in the higher-order vibration modes of the circular diaphragm 1.

PROBLEM TO BE SOLVED: To provide a manufacturing device for a plasma display panel capable of forming a uniform protection film with a good secondary electron emission characteristic and sputtering resistance on a PDP substrate. SOLUTION: In a PDP film formation device 1, two MgO ring hearths 8 and two electron guns 10 are arranged below the film formation position in the substrate 3. The electron gun 10 emits electron beams 12 to irradiation parts 11a and 11b in the ring hearth 8, and the irradiation parts 11a and 11b serve as evaporation sources of MgO. In the view from the upper side, one evaporation source (irradiation part 11a) is arranged on each outside of an area put between straight lines on the inside by 40 mm from the width directional end edges of the largest substrate 3 inserted into the film formation device 1. An angle θ between a straight line 14 connecting the center of the irradiation part 11a and the point closest to the center of the irradiation part 11 in the end edge 6a of a display area 6 and a horizontal line 15 extending in the width direction from the center of the irradiation part 11a is set to 80° or less.

Abstract:
PROBLEM TO BE SOLVED: To provide an inexpensive, reliable optical amplification device which can prevent optical surge with a simple optical circuit. SOLUTION: An input signal light 40 is inputted to an optical input off detector 43 where the light is branched into two light signals by a CPL(coupler) 45. One of two light signals branched by the CPL 45 is input to a light receiver 46 to be converted therein to an electric signal corresponding to the branched light power. The other light signal branched by the CPL 45 is input to an optical signal cut-off section 44 as it is. The electric signal converted by the light receiver 46 is compared by a controller 48 with a predetermined value. When the electric signal is smaller than the predetermined value, the controller 48 cuts off an optical path of a SW(switch) 47 to an optical direct amplifier 42. When the electric signal is larger than the predetermined value, the controller 48 controls connection of the optical path in such a manner that a control signal to the SW 47 varies more slowly than a time constant for constant output control of the optical direct amplification circuit 42.
Abstract:
PROBLEM TO BE SOLVED: To provide a filter circuit which achieves desired characteristics by equalizing the current flowing to a positive electrode-side winding and a negative electrode-side winding of a CMC. SOLUTION: The circuit includes: means (2, 3) for monitoring the current flowing to a positive electrode-side winding and the current flowing to a negative electrode-side winding of a common mode noise filter; and means (4, 5, 6) for adjustment, which make the positive electrode-side winding and the negative electrode-side winding equal to each other based on monitoring result.

Abstract:
PROBLEM TO BE SOLVED: To provide a communication terminal, a route guidance device, a route guidance system, and a route guidance method for performing guidance to a target place without imposing a burden on a communication network in particular even when communications concentrates as in the event of disaster occurrence. SOLUTION: A person who is to return home on foot in the event of earthquake occurrence, for example, previously makes a route guidance service contract and downloads a map of a walking route connecting a start point and a target point. This communication terminal acquires a present position while it requires, of this route guidance device, the latest walking route and data such as the distance to the target point and remaining time at some time intervals (steps S266 and S263) to display them together with the map and the present position on its display part each time they are received (step S265). Since map data are acquired prior to the occurrence of disaster, an overload of a communication network can be avoided. COPYRIGHT: (C)2008,JPO&INPIT
