Abstract: A gel layer retained in a retaining member 15, such as non-woven fabric, is placed on one side of an electrode element 1. The electrode element 1 is held by a flexible and extendable tape 11, and the tape 11 adheres to a biological surface tissue. When being plastered onto the biological surface tissue, the tape 11 is covered with cover films 12 and 13, thereby preventing occurrence of a kink in the tape 11. After the tape 11 has been attached to the biological surface tissue, a butt-joined portion between two sub-divisions constituting a cover film 12 is exfoliated to the outside, thus preventing removal of the tape 11.

A lock plate guiding long hole is formed in the upper rail. A lock spring locking means is provided on the lock plate at a portion corresponding to the lock plate guiding long hole in such a manner that the lock spring locking means is inserted into the lock plate guiding long hole and projects from the lock plate guiding long hole so as to lock the lock spring.

Abstract: Vinylphenol-type polymers are useful materials and are used in many fields such as photoresist, packaging material for IC, printed circuit board, lense, etc. When the polymers are used in an electronic field such as photoresist and packaging material for IC, it is desired to reduce metal concentration in the polymer in the order of ppb units. A simple and effective process for removing metals from vinylphenol-type polymers is disclosed. The process comprises passing an organic solvent solution of a vinylphenol-type polymer either through (a) a filter containing an ion exchange material and/or a chelate-forming material and generating a zeta (.zeta.) potential by a cationic charge modifying agent or through (b) (i) a filter containing an ion exchange material and/or a chelate-forming material and (ii) a filter generating a zeta (.zeta.) potential by a cationic charge modifying agent.

Abstract: An expandable column 10 is accommodated in an accommodating hole 12a so as to freely advance therefrom and retract thereinto. The expandable column 10 has a plurality of holes 11 disposed thereon in the advancing and retracting direction thereof. An actuating piece 13 extends from an end of a fixed frame 12 in the advancing and retracting direction of the expandable column 10.

The expandable column 10 is positioned by the engagement of one of the holes 11 with the pin 14 and the engaged state of both the hole 11 and the pin 14 is released by the swing motion of the actuating piece 13, so that the expandable column 10 can be expanded and retracted.

Abstract: A joint signal detection and channel parameter estimation scheme is provided for multiple subcarrier signaling with pilot symbol-assisted modulation schemes. Known symbols located in the subcarriers are used to estimate a pair of parameters associated with the generation process of the fading frequency selectivity common to all of the subcarriers. These known symbol estimates are used to derive parameter pair estimates for unknown symbols located in the subcarriers. This parameter estimation thus effectively extracts information regarding the fading frequency selectivity through the pilot symbols received not only by the subcarrier of interest but by other subcarriers as well. The fading complex envelope with each subcarrier is then derived from the estimates of the parameter pair.

The long arc-shaped hole is partly covered by a vertical wall of the second frame.

Abstract: A determinant, which represents the relationship between a sequence of code division multiplexed transmission symbol vectors b(k) from L communicators and a sequence of despread output vectors y(k) of received signals taking into account the cross correlation between spreading code sequences of transmitted signals, is limited within the range of .+-.g symbol duration about symbol timing k, and despread outputs of received signals within the limited range are inputted into a 2g+1-stage shift register. On the other hand, partial correlation matrixes R.sup.k+h (1), R.sup.k+h (0) and R.sup.k+h (-1) for each symbol duration within the limited range are calculated by a partial correlation computing part with respect to h=-g, . . . , g, then a correlation matrix R.sup.k between the spreading code sequences corresponding to the L communicators is derived from the partial correlation matrixes in an inverse matrix computing part and an inverse correlation matrix R.sub.k.sup.-1 of the correlation matrix is calculated.

Abstract: An up-link channel assignment scheme for cellular mobile communications systems employing multibeam antennas with beam selection, in which a channel that is selected from among all variable channels in the same frequency band may be assigned to each of the antenna beams in a base station for communications. Channel selection for a base station takes place independently of that for other cells, such that the process is autonomous. Channel selection is based upon an estimate of the signal-to-interference power ration ("SIR") in which a channel having the smallest SIR estimate that is larger than or equal to a given threshold value is chosen. Alternatively, a channel having the largest SIR estimate is selected.

Abstract: Mobile stations randomly set delay amounts for each message to be sent, on the basis of the timing of a symbol received from a base station, and delay transmission signals for time intervals corresponding to the delay amounts. The base station 11 despreads signals received from the mobile stations to extract basic symbol timing for each mobile station and, at the thus extracted timing, takes each despread output into the corresponding demodulator for demodulation.

Abstract: In a mobile communication system which uses a code division multiple access (CDMA) scheme for communications between a base station and a plurality of mobile stations, the base station has a transmitting device in which a plurality of information sequences S1 through Sn are respectively spread by multipliers 11 through 1n with a common spreading code from a spreading code generator circuit 10, the spread codes are provided to transmitting timing control circuits 21 through 2n and then added by an adder 30 to perform transmitting timing offset multiplexing and then the spread signals are transmitted to the mobile stations at different transmitting timing. The mobile stations each have a receiving device which receives that one of the transmitted signals which was transmitted at timing predetermined for the mobile station and despreads the received signal with the same spreading code as that used in the transmitting device, thereby reconstructing the original information sequence concerned.

Abstract: A base station of a CDMA communication system includes a transmission de-correlator for eliminating interferences between communication channels of a downlink. The transmission de-correlator has a memory storing a set of data representative of the products of transmission information bits for the respective channels, and the sums of the products of the spread code data sequences for the respective channels, and the elements of an inverse matrix with respect to a predetermined matrix of a cross-correlation between the spread code data sequences for the respective channels. The sums correspond to additions of the products along a direction of columns or to additions of the products along a direction of rows of the inverse matrix. A counting device is operative for causing the memory to sequentially output the data therefrom. An adder serves to calculate a sum of the data outputted from the memory.
