There is provided a catalyst module having a waste liquid inlet passage for the inflow of a waste liquid, whose partition wall is formed of fibrous activated carbon, in which: the fibrous activated carbon is impregnated with or contains a catalyst; and a waste liquid in the waste liquid inlet passage passes through the partition wall and is discharged out of the waste liquid inlet passage. Further, there is provided a catalyst module, in which a plurality of waste liquid inlet passages is arranged in the form of a bundle. In the catalyst module are also provided partition walls formed of a fibrous activated carbon layer prepared by laminating a plurality of the fibrous activated carbon in the form of sheets.

A frame synchronization apparatus is applied to the TDMA (Time Division Multiple Access) communication system, particularly, where a plurality of transmission rates are available. The frame synchronization apparatus calculates correlations between sampled sequences of a received signal and an assigned sync sequence during the longest or shortest frame period in the plurality of transmission rates. The apparatus stores positions where the correlations exceed a given threshold. Then, the apparatus sets a search gate at a position after a lapse of the longest or shortest frame period from each of those positions. The apparatus calculates correlations between the sync sequence and sampled sequences of the received signal for all the search gates. The actual transmission rate is determined from the plurality of transmission rates based on a time interval of positions where the correlations beyond a second threshold were detected. Synchronization is thus established.

An equalizer including a channel estimator allowing a Viterbi algorithm processor to estimate transmitted symbols accurately, so that the impulse response of a transmission channel may not deviate from the correct one. The equalizer outputs an transmitted symbol sequence estimate having the largest path metric by correcting the channel impulse response by parameter coefficients of the LMS (Least Mean Square) or RLS (Recursive Least Square) algorithm, by compensating for phase fluctuations due to the frequency offset and phase jitter of received signals, or by using a sequence included in an intermediate portion of a TDMA (Time Division Multiple Access) frame format.

A mold surface (6) of an upper mold (1) with which a fluid resin comes into contact has an oxide (3) therein. The oxide (3) contains a metal cation and an ion. Field strength is calculated based on a valence of the metal cation and an ionic radius of the ion. Based on predetermined relationship established between a value of the field strength and adhesion strength between a cured resin and the mold surface (6), releasability between the cured resin and the mold surface (6) is evaluated. Thereby, a method of evaluating releasability between the cured resin and the mold surface (6) is established. With this evaluation method, a material with high releasability (3) can readily be provided. Further, if the material with high releasability (3) is used for the mold surface (6) of the upper mold (1), a mold for molding a resin having excellent releasability can be obtained.

摘要:
A receiver to be employed in a digital mobile communication system, more particularly to a receiver for performing complex correlation against a received signal so as to establish and supervise the synchronization with the received signal. The receiver estimates a transmission channel between sending and receiving stations using the received signal and a predetermined reference signal (S11). The phase of the received signal is compensated for using the estimated phase error resulting from the estimation (S12). Complex correlation of the received signal which is compensated for in phase is performed against the reference signal (S13) to obtain a correlation value. The correlation value is compared with a predetermined threshold value (S14). The presence or absence of synchronization between the sending and receiving stations can be detected based on the result of the comparison. In case of detecting synchronization again after the synchronization is once detected, the phase of the received signal is compensated for (S22) using a previously obtained phase variation amount whereby the complex correlation value can be obtained (S23).
