Patent EP-0119611-A2 (EP)
Inventor: GEIST JACOB MYER
IPC: F28D9/00
Filed: 1984-03-16
Abstract: A method is disclosed for cooling, condensing and subcooling a substantially single component gas stream by passing the gas stream through a heat exchange relationship with a vaporizing multicomponent stream so that carry-up of the condensed liquid phase is maintained without condensed phase backmixing and pot-boiling of the coolant stream is avoided. The single component gas stream is passed through a cold-end up heat exchanger having a serpentine pathway for the gas stream comprising a series of horizontal passes separated by horizontal dividers and alternatingly connected by turnaround passes at each end. The method is particularly applicable to the condensing of a recycle methane stream in a nitrogen rejection process which uses a methane heat pump cycle to provide refrigeration.

IPC: H04B10/524
Filed: 1984-05-11
Abstract: An optical fiber communication system for transmitting information-bearing optical signals over an optical fiber transmission line includes a signal generator coupled to the transmission line for introducing information-bearing optical signals thereonto, preferably as wavelength modulated signals, and one or more optical amplifiers for periodically, collectively amplifying the transmitted signals to overcome the effects of attenuation. Wavelength modulation is achieved by altering the resonant characteristics of an optical resonator, optically coupled to a gain medium so as to provide an output that varies between a first and second wavelength. The optical amplification is achieved by injecting, preferably via lateral optical fiber couplings, pumping beams into the optical fiber so as to effect an increase in the amplitude of the information-bearing signals by stimulated Raman scattering.

Abstract: A two-valued height-based image of an object on a support surface is acquired in one frame time of a raster scan, television-like camera. Two rotating sheets of light projected by synchronized sources intersect at the supporting surface and form a moving light bar. The image of light bars incident on a 3D object is discontinuous because of the parallax effect. The light bar illuminates and sweeps out a rectangular area in step with the electronic scan of the scene imager.

Abstract: In a method for fabricating a thyristor in which n-type impurities are diffused in a p-base (12) of a pnp wafer to form an n-emitter (15), the step of diffusing the n-type impurities for forming the n'-emitter (15) has the conditions which are set not to exceed the range where the amount of doped impurities is smaller than that which is electrically activated, thereby performing the gettering process by diffusing n-type impurities in two surfaces of the pnpn wafer in which the n<sup>+</sup>-emitter (15) having no defects is formed. Even if a thyristor obtained by the above processes has a high off-state voltage, it has a low on-state voltage, a short turn-off time and a small variation in a reverse recovery charge.

Abstract: An HRC-fuse as an insulating body surrounding a main fusible conductor and an auxiliary fusible conductor connected to a spring biased impact pin. A conductive cap serving as a terminal for the fusible conductors is arranged on the insulating body and is provided with an outlet opening opposite the impact pin. A tripping hollow pin or sleeve coaxially surrounds at least a part of the impact pin and passes through the outlet opening. A bimetal release pawl is arranged in the one cap parallel to the pin and being electrically connected to the fusible conductors. The pawl engages a rest on the tripping sleeve to counteract a biasing spring. The impact pin and the tripping sleeve are triggered independently one from the other either by a short-circuit current melting the auxiliary conductor, or by an overload which heats up the bimetal release and triggers the sleeve. Both the tripping sleeve and the impact pin act on a load interruptor arranged opposite the outlet opening.

Abstract: A low insertion loss surface acoustic wave filter in which withdrawal weighted launching and output transducers 20, 40 are acoustically coupled by two high efficiency reflective multistrip couplers 6, 6'. To reduce the insertion loss, the inner bus bars 21, 41, are reduced in width so as to reduce the dead space 12 in the coupler. This makes it impossible to form a reliable wire bond connection to the inner bus bars which are therefore connected via a conducting path across the propagation path at the ends of the transducers. Further reduction in the widths of the inner bus bars and consequent increase in resistive losses are offset by several connections to a further bus 23, 43 via groups 25 of dummy electrodes arranged at null points in the weighting pattern.

Abstract: Radiation sensitive compositions are image-wise exposed and developed to form an image which is then heated to improve its strength as a lithographic printing image or etch resist. The heating is carried out in the presence of a heat sensitive dye which undergoes a colour change at a temperature of at least 180°C so as to obtain an indication of whether or not the heating has been adequate. The dye may be an integral component of the composition or it may be applied to the image, after development, in combination with a substance capable of forming a shield against contaminating residues produced during the heating step.

IPC: G11B7/09
Filed: 1984-06-29
Abstract: In an apparatus for detecting a focusing state of an optical system, a laser beam generated from a laser unit (8) is transmitted through a beam splitter (10) to a convergent lens (14). The laser beam is converged by the convergent lens (14) and projected toward the surface of an optical disk (16). The laser beam reflected from the disk (16) surface is reflected by the beam splitter (10) and projected through the aperture of a light shielding plate (18) to a photodetector (2). The photodetector has first and second photosensitive regions (2-1,2-2) arranged concentrically, and when the convergent lens is in a focusing state, the levels of the first and second photo signals from the first and second photosensitive regions (2-1, 2-2) are equal to one another, and the output signal from the differential amplifier (4) is maintained at zero level. When the convergent lens (14) is approached from the position sufficiently separated from the optical disk (16) to the position of the focusing state, a positive output signal is generated from the differential amplifier (4). When the convergent lens (14) gradually approaches from the position of the focusing state to the optical disk (16), the beam spot gradually becomes small on the photosensitive regions and again starts expanding, but the laser beam does not expand at a predetermined beam diameter at the position provided with the light shileding plate (18). Therefore, the beam is retained at a predetermined value. Consequently, the output signal from the differential amplifier (4) is not varied from the negative level to the positive level.

The movement of a selected one of the slide members (24,25) to its operative position turns the coupling member about the actuating member (51a,51b) on the other slide member (24,25) and thereby affects swinging of the pivot arm (42) in one direction or the other for establishing a corresponding mode.
