Abstract: A process comprising the steps of:
     1) reacting a norbornene compound of the formula:
      where R is H or methyl, R¹ is a direct bond or -C(=O)O- and R² is vinyl, ethynyl, allyl or propargyl, with a silicon hydride functional compound in the presence of hydrosilation catalyst at a temperature of at least 60 degrees; and   2) recovering a product which consists essentially of the addition products of the silicon hydride functional compound to the R² group of the norbornene compound and which is substantially free of addition products of the silicon hydride functional compound to the internal ring double bond of the norbornene compound.   
     The products of this process can be used to produce norbornene functional prepolymers which are useful in cureable silicone formulations based on thiolene or hydrosilation cure chemistry.

Abstract: A photosemiconductor device of the type in which light reaching a photosensitive layer (14;27;44) of a doped amorphous semiconductor material, between two electrodes (12,15;23,29;42,46) of the device, generates electron-hole pairs in that layer (14;27;44), the doping of the said amorphous semiconductor material being such that its conductivity is substantially equal to that of the purely intrinsic form of that material, is characterised by a layer (13;26;43) of non-doped amorphous semiconductor material interposed between the said photosensitive layer (14;27;44) and one of the said electrodes (12;23;42). 
     Preferably, the photosensitive layer (14;27;44) is doped with an acceptor, such as boron. 
     In such a device the degree of doping of the photosensitive layer can be decided more freely than in prior art devices of the said type.

Abstract: An ion cyclotron resonance mass spectrometer is externally calibrated, i.e. a calibrant compound is not present at the same time as the sample to be analyzed, by determining changes in the relative number of ions in the cell. This may be done by obtaining a spectrum of the sample to be analyzed, measuring the trapping sidebands, and then determining the trapping frequency from those sidebands as the difference between the trapping sideband frequencies and divided by four. The cyclotron frequency can then be found from the effective measured frequency and the trapping frequency, and the mass is then obtained as a function of the cyclotron frequency. Another approach is to measure the magnetron frequency directly, and then to calculate the cyclotron frequency from the measured effective frequency and the magnetron frequency. A third approach is to introduce a calibrant compound into the cell and produce several output signals with various relative numbers of ions. Calibration is accomplished by using the known relation 
m = k₁B/f + k₂E/f², 
or variations thereof, where m is the mass of the ion to be measured, k₁ and k₂ are constants, B is the magnetic field strength, f is the measured frequency for that ion, and E is an electric field term which is dependent on the cell geometry, magnetic field strength, and total number of ions present in the cell. An output signal is obtained for the sample under analysis and, by knowing the relative number of ions that is to be   incorporated into the E term, the values for the various factors can be inserted into the calibration relation to arrive at mass measurement values.

Abstract: An apparatus is described for rearranging the relative positions of data samples of a digital video signal within each field of the video signal, for use in a digital VTR in which alternate samples are separated into two different recording channels to be recorded on different tracks of a recording medium. The apparatus includes an intra-line shuffling circuit (101) and a field memory (103) into which output data from the shuffling circuit are written, such that adjacent samples which are of the same channel and are located mutually adjacent in the same line of the video signal are read out from the memory and recorded on respectively different tracks of the recording medium, thereby ensuring that if a sample is lost due to a read error, the adjacent samples of the same channel will always be available for use in interpolation processing to compensate for the lost sample.

Abstract: In known repeaters complying with CCITT Recommendation G.958, repeater sections are monitored by monitoring the transmission error probability of SDH signals (synchronous digital hierarchy) by means of parity evaluation. This requires the splitting-up and reconstitution of the SDH signal. Specific signal processing devices, such as multiplexers and demultiplexers, which are not needed for repetition of transmission signals as such, are required for this purpose, which causes a considerable power loss. In the repeater (RE) according to the invention, the transmission error probability is determined by comparison of a known word in the header part of an STM-N signal with a reference word. The transmission error probability is derived from the result of the comparison and fed via an error line (FL) to a central station. The transmission error probability can be transmitted in an STM-N signal in that it is effected via a repeater complying with CCITT Recommendation G.958 by using, for example, the service channel. <IMAGE>

Abstract: A method of and a system for controlling antilocking brakes (62, 66) employed in a vehicle (10) such as a motorcycle. The position of an expander piston (46) which constitutes an antilocking modulator (22) is detected and the torque of a rotative drive source (24) for actuating the expander piston is detected. A braking force used for each of the brakes is then computed from the detected position of the expander piston and the detected torque of the rotative drive source at the detected position. Further, friction coefficients of a road surface are estimated from the braking force thus computed and a target slip ratio is estimated from the estimated friction coefficients so as to carry out the optimum braking. Accordingly, the optimum target slip ratio can be estimated depending on high and low µ roads, thereby making it possible to provide satisfactory braking.

Abstract: Character recognition method and apparatus according to the present invention comprises the partial pattern dictionary which classifies and registers partial patterns of characters to be recognized in accordance with direction data of strokes and the partial pattern composition dictionary which classifies and registers dictionary characters in accordance with the partial patterns. When a character image to be recognized is inputted, each stroke is converted into direction data. The partial pattern dictionary is searched by using the attained direction data and divides the character image to be recognized into a single or plurality of partial patterns. The partial pattern composition dictionary is searched by using the partial patterns attained in the above-described way. A dictionary character is thus attained as the result of recognition.
