Abstract: PROBLEM TO BE SOLVED: To provide a thin film zinc oxide resonator having higher crystalline performance and orientation without giving any effect on its resistivity and to provide its manufacturing method. SOLUTION: This invention discloses the manufacturing method of the resonator. This method includes a step that provides a substrate base (50) having a dielectric layer. Then an adhesive layer (115) is formed on the dielectric layer and a new creation promoting film (120) is formed on the adhesive layer. Succeedingly a zinc oxide layer (125) is formed on the new creation promoting film and an upper side conductive layer (130) is formed on the zinc oxide layer.

Abstract: PROBLEM TO BE SOLVED: To provide an optical fiber with which transverse space modes are intrinsically separated from each other even when substantial perturbation exists. SOLUTION: According to an embodiment 1, an MOF is so designed as to simultaneously indicate relatively large abnormal dispersion and the intrinsically separated transverse space modes by forming the diameter of a core region below about 6 μm and making the difference between the effective refractive index of the core region and the effective refractive index of the cladding region greater than about 0.1 (10%). More preferably, the cladding region includes

Abstract: PROBLEM TO BE SOLVED: To provide a device and a method, using navigation data, which enable even a weak GPS signal affected by an obstacle such as a structure, etc., to be used for position measurement. SOLUTION: A radio terminal increases its total signal detection sensitivity by increasing integration intervals (e.g. >=20 ms) by performing data wipe-off operation by using estimated navigation data. After an intense GPS signal is detected, the intense GPS signal is demodulated to compute a satellite position table including navigation data. Then the demodulated navigation data are matched against known features of navigation data to estimate navigation data as to a weak GPS signal. Then the estimated navigation data are used to increase the integration intervals of the weak GPS signal, so that even the weak GPS signal can be detected by the ratio terminal.

Abstract: PROBLEM TO BE SOLVED: To provide a new routing protocol of Ad-Hoc network. SOLUTION: In this method, a source node holds the position information, routing information of all nodes inside a local node topology and the rough position information of partial nodes outside the local topology. When it is necessary for the source node to transmit a packet to a destination node inside the local topology, the routing information is already provided. When it is necessary for the source node to transmit a packet to a destination node outside the local topology, however, which node inside the local topology is closest to the destination node is specified while using the rough position information of the destination node. When this specified node is not the source node, the source node transmits the packet to the specified node and transmits the packet to the destination node later. In the other case, the packet is dropped.

Abstract: PROBLEM TO BE SOLVED: To provide a procedure for determining a method for mutually linking software switches for dealing with call setup in the process of call setup in Internet telephony. SOLUTION: In this method practical for designing a CC network into arbitrary size satisfying a limitation to a network diameter and a CC degree with a high probability, the network of CC is first handled as the set of separated points as one point for each CC. Then, the pairs of CC are linked. A fraternal pair (pair existent inside the same switch) is excluded from this pair. Namely, respective admissible pairs (respective pairs out of the same switch) are linked or are not linked.

Abstract: PROBLEM TO BE SOLVED: To provide a transmission method and device for a data stream with an enhanced error permissible power. SOLUTION: In the transmission method for a data stream, a coding unit 202 encodes a source data word consisting of k-sets of symbols in a received data stream to generate a code word consisting of n-sets of symbols larger than number (k). A slice unit 204 slices each of code words consisting of n-sets of the symbols into a plurality of code word slices. A distribution type transmissions unit 206 routes the encoded slices along a plurality of parallel paths to generate a plurality of routed code word slices. A combination unit 210 combines a plurality of the routed code word slices to generate a plurality of the routed code words consisting of n-sets of the symbols. A decoding unit 212 decodes the routed code work consisting of n-sets of the symbols to generate the routed data word consisting of k-sets of the symbols in an output data stream corresponding to the source data word consisting of k-sets of the symbols in the input data stream.

Abstract: PROBLEM TO BE SOLVED: To provide an analog/digital converter(ADC) that can reduce the conversion spurs (whiskers) related to the nonlinearity of an AD conversion function. SOLUTION: One embodiment of this invention indicates that an analog dither signal is fed to an analog input signal before a quantization process. The dither signal used for the integrated circuit of this invention has a variable amplitude controlled by a processor. Then the processor decides the amplitude of the dither signal to be added to the analog input signal by analyzing quantization digital indication of the input signal with the dither signal added thereto. The amplitude of the dither signal depends on a power level of one carrier or more in existence in the analog input signal. Adding the dither signal to the analog input signal can reduce the conversion spurs caused by the nonlinearity of the AD conversion function.

Abstract: PROBLEM TO BE SOLVED: To efficiently detect a preamble in data. SOLUTION: A preamble detector determines a preamble bit corresponding to a received sample z(n) by slicing the received sample z(n) at a threshold. The preamble detector is provide with an option filter, averaging circuit and comparator. Before generating a determination d(n) by the comparator concerning the input sample z(n), an average sample zfa(n) is generated by averaging filtered samples zf(n) and zf(n-k) by adopting the averaging circuit so that reliability in the determination to be performed concerning the correspondent sample can be improved. As one implementation style, as 4-sample delay bank provided with four flip-flops, adders and option output buffers to be used for storing the average sample zfa(n) to be provided to the comparator is adopted for the averaging circuit.

Abstract: PROBLEM TO BE SOLVED: To provide structuring, detection and estimation technology of a signal used for uplink timing synchronization and access control in a wireless communication system adopting the orthogonal frequency division multiplex system(OFDM) or other types. SOLUTION: In an illustrative embodiment of this invention, a timing and access signal transmitted in designated timing and a designated access interval is structured with an orthogonal multi-tone signal. The multi-tone signal can be obtained similarly to the case with a multi-tone signal used for transmission of OFDM data except for correspondence of the multi-tone signal to a timing error of a mobile station not synchronized yet through the extension of a cyclic prefix related to reception of the signal by a base station.

Abstract: PROBLEM TO BE SOLVED: To provide a technology to realize uplink timing synchronization and access control with respect to a wireless communication system in general especially in a multi-access wireless communication system. SOLUTION: A mobile station of this invention transmits a general-purpose uplink access signal at any of intervals. When this access is permitted, a base station transmits access confirmation including initial timing and power correction together with designation of an initial channel at which the mobile station can start call setup process. For re-synchronization, the mobile station transmits a timing synchronizing signal in exclusive timing and at an access interval. The base station measures the arrival time of the signal and returns proper timing correction. Thus, the orthogonality between mobile stations can surely be maintained.
