Patent EP-0510967-A2 (EP)
Inventor: TU CHING-FANG
IPC: G02B6/44
Filed: 1992-04-23
Abstract: An optical fiber cable (20) includes a core which (22) is filled with a filling material (26) comprising a composition of matter which passes industry wide drip test, which substantially has no oil separation and which has excellent thermal oxidative stability. The filling composition includes a relatively high molecular weight aliphatic hydrocarbon which may be a polyalphaolefin, for example, or a relatively high molecular weight mineral oil. Also included in the composition of the filling material is a fumed silica, a block copolymer and a relatively high amount of an antioxidant system. Swelling of coating materials for optical fibers (25,25) which are relatively soft and which are in contact with the filling material is substantially less than experienced with prior art filling materials. Because of the inclusion of a low pour point aliphatic hydrocarbon in the filling material, the cable provides excellent optical performance at low temperatures.

Abstract: A device (11) for magnetically treating a hydrocarbon fluid in a fuel line (21). 
     The device (11) includes a plurality of annular magnetic portions (L1-L3) each having a central aperture (17) which are aligned coaxially to form a central bore (19) through which the fuel line (21) is threaded. The central apertures (17) have varying diameters and are arranged in a graduated sequence starting with the smallest aperture (L3) at one end of the device and the largest aperture (L1) disposed towards the other end. The magnetic portions (L1-L3) are arranged so as to provide a uniformed magnetic field having poles of opposite polarity disposed at opposite ends of the bore (19). Optionally, a further magnetic portion (31) in the form of an inductive coil (33) may be incorporated into the device adjacent to the first magnetic portions (L1-L3) so that the fuel line can pass through the central bore (45) of the coil immediately after the central bore (19) of the first annular magnetic portions. Alternatively, the device can be fitted upon a spark plug (71) to magnetically treat fluid in a combustion chamber prior to and during combustion.

Abstract: Device for generating a DC voltage with a low ripple for the purpose of powering an X-ray tube between a positive high voltage HT+ and a negative high voltage HT-. The invention lies in the fact that the device comprises a first inverter 31 for supplying the positive high voltage HT+ and a second inverter 32 for supplying the negative high voltage HT-. These inverters are controlled by signals whose phases vary as a function of the sum of the absolute values of HT+ and HT-, of the difference of their absolute values and of the difference of the phases of the currents flowing in the inverters 31 and 32.

Abstract: A pi/4 shift QDPSK signal is hard - limited (33) and subsequently fed to an edge detector (40), responsive to the rising edges of the limited signal. A reference clock (45), the frequency of which is an integral multiple of the carrier frequency, increments a counter between the rising edges of the modulated signal, which then gives a measure of the phase. The difference between subsequent phases is then calculated (130) to give the data.

Abstract: A nasal positive airway pressure device is provided having a pair of nasal members each having a cannula tip to be inserted into the nares of the patient. Each cannula is tapered from a substantially circular cross-section outside the patient's nostril to a substantially oval cross-section at the tip inserted into the nostril. An inflatable cuff surrounds each cannula with the interior space of the cuff communicating with the lumen of the cannula through at least one aperture in the side wall of the cannula. The nasal members are connected to one or more flexible hoses which, in turn, are connected to a source of positive air pressure. In use, positive air pressure is supplied to the each cannula tip through the air hoses and nasal members. The positive air pressure inflates the cuffs to hold the nasal members in place and to effect treatment. The tapered tip configuration, soft inflatable cuffs and adjustable positioning of the nasal members and tip provide a device which is more comfortable to the user. A variable diameter orifice for nasal positive airway pressure treatment is also contemplated.

Abstract: A voltage at the plate line PL is fixed at an intermediate voltage Vm. A precharging and balancing circuit 3 precharges bit lines BL11 and BL12 to a ground level before certain word lines WL is reduced into a selected level by an external address signal. Thereafter, access is made to a memory cell. Then, an intermediate voltage supplying circuit 5 maintains the bit lines BL11 and BL12 at the intermediate voltage Vm. Thereafter, the certain word lines WL are reduced in turn into a selected level, and thus a transistor T of the memory cell MC is activated to thereby compensate for a voltage at a cell node Nmc to the intermediate voltage Vm. The ferroelectric memory device in accordance with the invention accomplishes higher speed operation and lower consumption of electric power, prevents destruction of stored data, and simplifies voltage control and operation control of word lines.

Abstract: The PLL includes a comparator which compares a signal derived from an input clock frequency and a signal derived from a VCO clock frequency. A VCO controller responds to the comparator output signal and produces a VCO control signal. The VCO includes a multi-stage oscillator portion which oscillates at the VCO clock frequency during a steady state condition under the control of the VCO control signal. The oscillator portion develops a number of clock phases at the VCO clock frequency, with the VCO control signal responsive to one of these clock phases. A combinational logic portion responds to at least some of the clock phases which it combines to create an output clock with an output clock frequency which is a multiple of the VCO clock frequency.
