Abstract: A process for producing monoclonal antibodies specific to carcinoembryonic antigen (CEA), comprising immunizing a mammal with a first CEA to produce cells capable of producing antibodies, collecting the cells from the mammal, fusing the collected cells with the cells of a line of a myeloma of another mammal, selecting the thus-obtained hybridoma cells on the basis of their capacity to produce antibodies reactive with said first CEA, subjecting the thus-selected hybridoma cells to cloning, selecting the thus-obtained monociones on the basis of the reactivities of monoclonal antibodies produced by them with at least one antigen selected from CEAs other than said first CEA and CEA-related antigens of normal adult human origin, culturing the thus-obtained monoclones and recovering the desired monoclonal antibodies from the spent culture. The selection may preferably be effected by radioimmunoassay using a marker antigen labelled with a radioactive substance. Monoclonal anti-CEA antibodies thus-produced have specific reactivity with the antigenic determinants of CEA molecules and thus may with advantage be used for various clinical applications and fundamental medical studies such as, for example, for determination of the concentration of CEA and CEA-related antigens.

Abstract: in a D/A converter in a deflection system of an electron beam exposure device, the most significant bits (m bits) of input digital data consisting of n bits are input into a decoder circuit, and 2 m  D/A converters which correspond to the m bits are provided. The data consisting of the least significant bits (n-m bits) is input into the 2 m  D/A converters via 2 m  gates, respectively. The decoder circuit is constructed so as to control the 2 m  gates so that when the content of the data of the m bits is S, the first to S-th data of the 2 m  D/A converters is all rendered to be "1", the data of the (S+1)-th D/A converter remains the same as the data of the n-m bits, and the data of the (S+2)-th and subsequent D/A converters is all rendered to be "0", the sum of the outputs of the 2 m  D/A converters being applied to a coil which deflects the electron beam.

Abstract: Monolithic microwave integrated circuits with resistance-capacitance coupling include bonding or terminal pads 20. 22. 26, 27 and 28 such as pads for signals, for a power source, and for bias potentials. In addition contact pads 21, 23, 24 and 25 are provided to enable the direct current characteristics of the circuit to be measured. These contact pads 21, 23, 24 and 25 can be contacted by probes when the circuit still forms part of a wafer to enable circuits with the required direct current characteristics to be selected for final assembly and packaging. The contact pads 21. 23. 24 and 25 are provided by opening up contact windows over electrically conducting parts of the circuit elements such as over metal electrodes of capacitors 5, 6, 7 and 9 which avoids the need to add to the area of the electrical conductors and hence enables the selection to be performed without sacrificing or impairing the high frequency characteristics of the circuit.

In this arrangement, the sensor can be mounted, together with other sensors of the same type, on a measuring and/or handling and/or machining device which can be positioned by means of an electronic control system. The measuring arrangement operates with one or more reference distances between sensor and object to be measured, the magnitude of which distances is determined by the distance between the object to be measured and the sensor at which the end face of the optical fibres is imaged on the object to be measured. <IMAGE>

Abstract: In digitally encoded data transmission systems such as paging systems using a code word format, such as POCSAG, each code word includes a number of bits collectively termed the cyclic redundancy check bits. In a paging receiver the cyclic redundancy check bits are used to determine if there are errors in the received message code words. If an error is detected then one bit random error correction is generally applied because it has a more acceptable falsing rate compared to say two bit random error correction or four bit burst error correction.In a POCSAG paging system described as an example the option of one bit random error correction or a less acceptable falsing rate correction technique, such as four bit burst error correction, can be given if additional protection against falsing is provided. The additional protection is to include error detection check bits in the entire message which is transmitted by the base station. At the receiver any errors in the message code words are subjected to four bit burst error correction and thereafter the entire «corrected» message is subjected to a further check using the error detection check bits. Wether or not error detection check bits have been included in the message is indicated by preconditioning the message, for example by using predetermined ones of the plurality of addresses allocated to each pager for different purposes. If error detection check bits have not been included a more acceptable falsing rate correction technique is applied.

Abstract: A stripping apparatus for stripping coated electric wires has a pair of clamping plates (36) movable into and out of contact with each other and provided with cutting edges (36a, 36b, 36c) formed at a constant pitch in their opposing contactable edges. The corresponding cutting edges in both clamping plates cooperate with each other in defining, when the clamping plates are held in contact with each other, cutting gaps of different sizes. The clamping plates are arranged to clamp and sever, at their cutting edges, the end portion of the coating d on the coated electric wire at least partially. Means (5,6,3) are provided for causing a relative movement between the coated electric wire and the clamping plates thereby to remove the severed end portion of the coating from the core wire of the coated electric wire. The clamping plates are arranged to be moved also in the direction substantially perpendicular to the coated electric wire to bring to the cutting position one of the cutting gaps having the size corresponding to the diameter of the coated electric wire to be stripped. This stripping apparatus can cope with the demand for stripping of coated electric wires of various different diameters.

Abstract: The present invention relates to a novel semiconductor device, such for example, an NPN bipolar transistor including a standard highly doped N +  emitter (28) separated on its sidewalls fom the P +  extrinsic base region (29) (base contact reach through) by a guard ring shaped region (30) having a significantly lower impurity concentration than the emitter (e.g. N - ). Said region (30) is located beneath an insulating spacer (25). 
     The initial steps of the process are basically standard. The extrinsic base (29) is formed from a boron doped polysilicon contact region (16). The N *  emitter region (28) is self aligned with the P +  polysilicon contact region (16), and remains separated thereof by said N region (30). The N +  emitter (28) is formed either using ion implantation techniques or a doped emitter polysilicon contact region. However, according to the teachings of the present invention, the intrinsic base (22) of the transistor is formed in situ, by a low dose low energy P type ion implantation through a mask, made with its concentration peak below the device surface. Subsequently, an intermediate N -  region is formed by implanting N type impurities through the same mask just to convert superficially the conductivity of the top surface above the P intrinsic base into N type. The N +  emitter may be then formed in such a way it is separated from the extrinsic base by a guard ring shaped portion (30) of said lightly doped intermediate N -  region. The transistor thus formed will have a controllable narrow base width and optimized concentration, and will exhibit desired low external resistance through the extrinsic base region. Both factors are essential to provide high speed and low power devices. 
     In addition, this transistor has a significantly high β factor (in the range of 150) with a limited modulation of said gain factor; it has also good Emitter-Base breakdown voltages (in the range of 6V). 
     Lastly, it presents increased inverse β which is a highly desirable factor for Merged Transistor Logic (MTL) applications.
