Abstract: It is expected that lectins of a needed number of types appropriately corresponding the variation of sugar chains, if available, are highly useful as tools for analyzing various sugar chains. From a lectin library containing plural types of lectins or an arbitrary mass of lectins containing plural types of lectins, lectins needed for analyzing sugar chains are selected to thereby construct a lectin sub-library. Using the lectin sub-library thus constructed, cells having sugar chains are identified. Moreover, an indication method whereby cells can be conveniently identified is provided.

Abstract: A CDMA radio device is provided which is capable of reducing a hardware scale and providing more accurate path selection with low power consumptions. A down-sampling part outputs data of which sampling frequency is made lower than A/D sampling frequency. A correlator part performs correlation calculation of the data using specific spread codes designated in cell information to create a delay profile. A first path selection part selects a path in the delay profile and transfers selection information to an up-sampling part. The up-sampling part supplements delay profile data at sampling time that has been lost in the down-sampling part. A second path selection part transfers some location information of ultimately determined paths to a base station spread demodulation unit or a mobile station spread demodulation unit as a path timing signal.

Abstract: A plurality of finger units despread a received signal with a first spread code to output pilot signals of a receiving channel which has been spread with the first spread code. An AFC unit despreads the received signal with a second spread code to output a pilot signal of an AFC channel which has been spread with the second spread code. An automatic frequency controller calculates a difference between an oscillating frequency of a oscillator and a frequency of the received signal for the channels based on the pilot signals of the receiving and AFC channels to supply a frequency control signal to the oscillator, whereby the oscillating frequency of the oscillator is controlled so that the oscillating frequency is substantially equal to the frequency of the received signal.

Abstract: Digital data is generated by sampling an analog input signal at a sampling frequency that is N times an A/D sampling frequency that is necessary in an A/D converter.

Abstract: There are a receiving unit for receiving a TDMA signal which is FSK (FM) modulated by a signal containing known information, and a demodulating unit 103 for demodulating received data. The demodulating unit 103 outputs a demodulated signal in a direct connection to a C-coupling. A C-coupling demodulation signal is inputted to a synchronization detecting unit 105, and a directly connected demodulation signal is inputted to an AFCBU 106. After a power supply is turned on, the C-coupling demodulation signal is inputted to the synchronization detecting unit 105. The demodulation signal whose synchronization state is being detected is inputted to the AFC unit 106 in a parallel condition and in a direct connection condition. After the synchronization signal is detected, a frequency offset correction is applied to thereby change a frequency offset of the frequency-converted signal by a carrier wave frequency converting section 10.

Abstract: In a secret information identification system, an input password is compared with a registered password every time a permission signal is generated. Lock release permission is given when a comparison result indicates coincidence. Alternatively, an input password is compared with a registered password and lock release permission is given every time a permission signal is generated when the comparison indicates coincidence. The cycle of generation of the permission signal is elongated as the number of events of non-coincidence in comparison results increases. As a result, the password is not easily broken, and further the password input function is not locked even after input of a wrong password.
