Patent EP-0296746-A2 (EP)
Inventor: KIM BYOUNG YOON
IPC: G01C19/64
Filed: 1988-06-13
Abstract: An interferometer used as a rotation sensor is constructed using a strand of optical fiber (112), a portion of which is formed into a sensing loop (114). A pair of lightwaves (W₁, W₂) are caused to counterpropagate in the sensing loop (114) and are combined to form an optical output signal that has an intensity that varies in accordance with the difference in the phases of the two counterpropagating lightwaves (W₁, W₂). A phase modulator (192) is positioned on the optical fiber (112) in the sensing loop (114) at a location such that the two counterpropagating lightwaves (W₁, W₂) are modulated approximately 180° out of phase. The time-varying phase modulation causes a time-varying phase difference (ΔΦ M (t)) that is combined with a rotationally-induced Sagnac effect phase to provide a total phase difference that is detected by a photodetector (160). The photodetector (160) provides an electrical output signal this is differentiated to provide a differentiated output signal (520, 450, 460) that has zero-crossings (H′, L′) that correspond to maxima and minima of the electrical output signal. The time intervals (Δt₁′) between selected zero-crossings (H′, L′) are measured and the rotationally-induced phase difference (ΔΦ R ) caused by the Sagnac effect is calculated from the measured time intervals (Δt₁′) The rotation rate (Q) is then calculated from the Sagnac phase difference (ΔΦ R ).

Abstract: A cartridge (6) for a multistrike typing ribbon (21) for printing machines engages a single drive shaft (51) for unidirectional advance movement of the multistrike ribbon (21) and comprises a container having a bottom (8) and two arms which project from a rear wall and which each have an aperture for the ribbon to pass therethrough. An epicyclic transmission arrangement (40) is disposed on the bottom (8) and comprises a series of toothed gears (48, 52 and 53) which are coplanar with each other and parallel to the bottom (8). The drive shaft (51) is engaged with a feed sleeve (49) of the cartridge and is coaxial with the feed roller (42) for the ribbon (21). The feed sleeve (49) is fixed with respect to the sun gear (52) of the arrangement (40), the sun gear being engaged with the planet gear (48) which in turn is rotatable on an eccentric pin (47) of a plate (46). The plate (46) is fixed with respect to a second sleeve (44) which is rotatable about the sleeve (49) and on which the feed roller (42) is fixed.

Abstract: According to the method, liquids, in particular flowing water, are treated with a pulsating magnetic field in order to prevent above all the formation of deposits on the walls of conduits and containers. To increase efficacy and to ensure that the "polywater clusters" which are critical for the formation of deposits are excited at their resonant frequency, the excitation frequency of the magnetic field is selected from two or more possible frequency values depending on operating conditions or is varied during operation between pre-defined limits. A device for carrying out the method, with a magnetic coil which generates a pulsating magnetic field in the flow path of a liquid, has an excitation unit with an oscillator which can be set to at least two different frequencies.

Abstract: In a planar linear pulse motor, relative movement between the stator and the armature is positively restricted when no electric current is supplied to the drive coils by means of a lock member provided in on of the armature and the stator which is attracted to a permanent magnet by its biasing magnetic flux to be brought into contact with the other of the armature and the stator. Therefore, the armature can be locked up without consuming any electric power. Further, by attaching the lock member to the stator or the armature by way of an elastic member whose two ends are fixedly secured to the stator or the armature as the case may be, not only the vertical dimension required for the elastic member can be reduced but also the mechanical strength and the security of the engagement can be ensured, thereby offering a planar linear pulse motor which is compact and highly reliable. In particular, when the lock member is mounted on the stator, there is no increase in the moving mass, and the response speed of the pulse motor would not be impaired by provision of such a locking mechanism.

Another method comprises a single process for erasing a recorded information, at a desired moment in the course of which a fresh information is recorded by prolonging interval between two laser beam irradiations.

Abstract: A unipolar electronic device is proposed which has a quasi-one-dimensional carrier channel having all the properties of an FET. This device can be produced very simply, has self-alignment and has linear instead of planar gates with very low capacitance. This makes a very high device operating frequency possible. The structure comprises an initially homogeneous 2D layer with high carrier mobility produced by epitaxy of, for example, GaAs. The conductivity of the n-type layer is locally destroyed by implanting focussed ions (for example, Ga<+> at 100 keV). The irradiated regions are still nonconductive even after illuminating the crystal with band-gap radiation at low temperature or room temperature. The insulation layer is inscribed along two paths on the chip, thus subdividing the 2D carrier layer into three regions which are insulated from one another. Source and drain are only linked by a narrow channel (44) whose width is continuously adjustable by means of a gate voltage simultaneously applied to the two gate regions relative to the source so as to result in a marked change in the carrier concentration and, consequently, in the channel resistance. <IMAGE>
