Abstract: A production method of a hydrogenated product of aromatic polycarboxylic acid by the hydrogenation of aromatic ring of the aromatic polycarboxylic acid in the presence of a catalyst composed of rhodium in combination with palladium and/or platinum supported on a carbon support. By using the catalyst, the hydrogenated product of aromatic polycarboxylic acid is produced industrially advantageously in high purity and high yield. By activating the catalyst composed of rhodium in combination with palladium and/or platinum supported on the carbon support after the hydrogenation, the conversion to the hydrogenated product of aromatic polycarboxylic acid is maintained at nearly 100% even after repeatedly using the catalyst many times. Also, a hydrogenated product of aromatic polycarboxylic acid substantially free from the starting aromatic polycarboxylic acid is obtained.

Abstract: A multicarrier transmitting apparatus capable of providing a fast cell search. A base station apparatus (100), which serves as a multicarrier transmitting apparatus for transmitting frames each including, as synchronization channel sequences, first synchronization sequences (P-SCH sequence) used for timing determinations and second synchronization sequences (S-SCH sequence) different from the first synchronization sequences, comprises a frame forming part (130) that forms frames each including the first synchronization sequence (P-SCH sequence) disposed in each of subcarriers symmetrical with respect to a DC component subcarrier (DC subcarrier) in the frequency direction; and an RF transmitting part (160) that transmits the frames. In this way, a frame receiving end can use a filter having a polarly symmetrical pass-band and needs no frequency shifting process, with the result that the processing amount at the receiving end can be reduced and hence a fast cell search can be achieved.

Abstract: A system can suppress the degradation of the system's own throughput, while suppressing the interference with a different communication system sharing a frequency band with the system. In ST302, a base station selects a terminal (B) as a relay station. In ST305, the base station performs a separation between the subcarrier signals outside an FSS-used band and the subcarrier signals within the FSS-used band, and remaps the separated subcarrier signals within the FSS-used band to the subcarriers outside the FSS-used band. In ST306, the separated subcarrier signals outside the FSS-used band and the remapped subcarrier signals outside the FSS-used band are differentially transmitted at the same time. In ST308, the terminal (B) remaps signals received from the base station to the subcarriers within the FSS-used band and, in ST309, transfers those signals as remapped to a terminal (A).

Abstract: A reception apparatus and a reception method improving the effect of interference suppression and reducing interference to the side subject to interference. A satellite signal demodulation unit (201) demodulates and performs a CRC check on a received satellite signal, while a satellite signal modulation unit (202) modulates the demodulated results outputted from the satellite signal demodulation unit (201). An adder (203) subtracts an output signal of the satellite signal modulation unit(202) from the received satellite signal, and an output switching unit (204) feeds back the signal outputted from the adder (203) to an IMT transmission apparatus (100) in cases when the CRC check result outputted from the satellite signal demodulation unit (201) is “pass”. Further, when the CRC check result is “fail”, the output switching unit (204) feeds back the received satellite signal to the IMT transmission apparatus (100).

Abstract: Reduction in the detection accuracy of synchronization timing at the receiving end is prevented even if a GCL system changes in response to a GCL ID. A transmitter (100) has a GCL system generating section (101) for generating a GCL system signal, a scramble processing section (102) for scrambling the GCL system signal, and a sub-carrier mapping section (103) for arranging the scrambled GCL system signal in a sub-carrier in the direction of a frequency. With this, the peak width of the differential correlation value of the GCL system at the receiving end is narrowed, so that accurate synchronization timing can be detected at the receiving end.

Abstract: In the production of an alicyclic aldehyde, a starting aromatic aldehyde is converted into an aromatic acetal for protecting the formyl group. The aromatic ring of the aromatic acetal is then hydrogenated to convert the aromatic acetal into an alicyclic acetal, which is then hydrolyzed to cleave the acetal protecting group to obtain the aimed alicyclic aldehyde.
