Disclosed is a complex which comprises a carbon nanotube and a modified polysaccharide having a backbone chain with the side thereof being introduced with monosaccharide or oligosaccharide residues. The polysaccharide is preferably β-1,3-glucan. The complex is prepared by admixing a solution of the modified polysaccharide dissolved in an aprotic polar solvent or a strong alkali solution with an aqueous dispersion of the carbon nanotube, and incubating the mixture.

A connector is provided with a shorting terminal. Male terminal fittings 12 protrude into a hood 11 of a male housing 10, a female housing 20 fitting into this hood 11. A left half of a lower portion of the hood 11 protrudes downwards, a shorting terminal housing recess 70 being provided at this location, this recess 70 housing a shorting terminal 60. The shorting terminal 60 has four resilient contacts 62 which make contact with the male terminal fittings 12 and short-circuit them. The shorting terminal 60 can be inserted, from the posterior of the male housing 10, into the recess 70. A misalignment preventing wall 75 protrudes at an anterior end of the recess 70. A protruding anterior end face of the misalignment preventing wall 75 forms a unified face with a right half of the lower portion of the hood 11. As a result, an opening area of the hood 11 of the male housing 10 is approximately the same shape as a fitting area R of the female housing 20, thereby preventing misalignment when fitting is carried out. The misalignment preventing wall 75 ensures that only a small part of the shorting terminal 60 is exposed to the exterior.

A connector includes first and second housings (10; 20). A lock arm (27) is formed on the second housing (20) and includes a lock (30) and striking portions (31). The lock (30) moves onto a locking projection (13) of the first housing (10) during a connecting operation and engages the locking projection (13) when the housings (10; 20) are connected properly. The striking portions (31) are formed separately from the lock (30) and produce a sound upon striking upon the first housing (10) when the housings (10; 20) are connected properly with each other. Since the striking portions (31) or producing a striking sound and the lock (30) for locking are separately formed, a vertical dimension of an engaging area of the lock (30) with the locking projection (13) can be reduced to suppress a degree of elastic deformation of the lock arm (27) while securely producing the striking sound.

A carrier recovering apparatus, in which degradation of the demodulation performance caused when a pilot signal cannot be normally received is suppressed, includes a rotation calculator for multiplying a baseband signal and an oscillation signal and outputting a multiplied signal; a pilot signal extractor for extracting a pilot signal from the signal output from the rotation calculator; an error detection controller for outputting a phase error between the pilot signal and a reference signal as a value restricted within a given range; a loop filter for smoothing the phase error output from the error detection controller and outputting the smoothed phase error; and a variable frequency oscillator for generating a signal in accordance with the output of the loop filter and outputting the generated signal as the oscillation signal.

Each of a first oversampling filter and a second oversampling filter oversamples to an n×m times as high frequency as a symbol rate. The first and second oversampling filters then output output data having a sampling frequency to first and second CIC filters, respectively.

The invention avoids the problem of resilient stopping arms losing their resilience. A female housing has a locking arm capable of engaging with a locking member of a male housing protruding therefrom. A detecting member is attached to a posterior side of this female housing. A pair of resilient stopping legs extend in an anterior direction from a main body of the detecting member. Anterior end portions of the resilient stopping legs have outwardly protruding hook-shaped protrusions protruding therefrom, these engaging with temporary stopping holes or main stopping holes provided in side walls of the female housing. Retaining protrusions protrude further outwards from protruding anterior ends of the resilient stopping legs. These retaining protrusions protrude to the exterior of the female housing from the temporary stopping holes or the main stopping holes. Recessed grooves corresponding in location to the main stopping holes are formed in inner side faces of a hood of the male housing. The retaining protrusions that protrude from the main stopping holes are inserted into these recessed grooves in the hood. When the detecting member is in an operating position and the resilient stopping legs are in an inserted state within the main stopping holes, these resilient stopping legs return to their original free state.

A detecting member 40 is attached within a female electrical connector housing 20 in a manner whereby it is capable of moving in a width-wise direction. A contacting face 47 of a detecting protrusion 46 of a detecting arm 45 makes contact with a locking arm 26 when this locking arm 16 is in a free state prior to two housings 10 and 20 being fitted together, this contact regulating the movement of the detecting member 40. When the two housings 10 an 20 are being fitted together, the contact face 47 of the stopper arm 45, and a side face 53 of a main body 41 make contact with a side face 51 of the bent locking arm 26, thereby regulating the movement of the detecting member 40. After correct fitting is completed, the locking arm 26 returns to its original position. Consequently, the contacting state of the stopper arm 45 and the main body 41 with the side face 51 is released, thereby allowing the detecting member 40 to be moved to a position indicating correct fitting of the housings 10, 20.

A first interpolation section 14 and a second interpolation section 24 perform sampling on input data Id4 and Qd4 having a sampling frequency fover so that resulting data will have a sampling frequency fsamp, which is equal to an operating clock frequency of a digital-to-analog converter, which is an output destination. In the above manner, the data is interpolated. At this time, the first interpolation section 14 and the second interpolation section 24 perform interpolation using a frequency ratio between the sampling frequency fover and the sampling frequency fsamp. Then,output data Id5 and Qd5 having the sampling frequency fsamp is outputted to a quadrature modulation section 31.
