Abstract: A process for the preparation of spherical, hard, mono- or oligodisperse particles having a diameter of from 0.1 to 100  mu m, by condensation of partially etherified melamine-formaldehyde precondensates which are infinitely soluble in water to give a clear solution, in an aqueous solution of a water-soluble polymer which carries highly acidic groups and has a K value of from 100 to 160, at pH 3 to 6 and at from 20 to 100 DEG C, and condensing the resultant turbid solution until the precondensate has been consumed, giving a dispersion of the particles. The dispersion is neutralised. The particles can be used in the form of the aqueous dispersion or after isolation from the dispersion. …<??>The particles are spherical, hard, non-swellable particles which can be used, for example, as sizes for plastics, polishes, flatting (matting) agents, extruders and/or as pigments. …<??>The process allows the targeted preparation of particles of a prespecified size and particle size distribution.

Abstract: A triple-action latch assembly (12) for a shipping case (10) having first and second housing members (14, 18) includes a U-shaped flexible slide (46) movably received on a T-shaped rail (30) associated with the first housing member (14). The slide (46) includes a first detent (68) engageable with an end portion (80) of the rail (30) to secure the slide (46) against movement. The slide (46) further includes a second detent (86) defined by a latch bar (88) having a latch beam (94) engageable with a first cavity (100) in the rail (30) to further secure the slide (46) against movement relative to the T-shaped rail (30). When the first detent (68) is lifted out of engagement with the rail (30) and the second detent (86) is simultaneously depressed to lift the latch beam (94) out of engagement with the first cavity (100), the latch assembly (12) can be slid to the open state. In this position, the latch beam (94) engages a second cavity (102) located within the rail (30) and the first detent (68) engages a third cavity (106) also located in the T-shaped rail (30). The second and third cavities (102, 106) include sloped and inclined surfaces (104, 108), respectively, that act to automatically cam the latch beam (94) and first detent (68) out of the second and third cavities (102, 106), respectively, to permit the slide (46) to be merely moved from the open state to the locked state.

Abstract: A speech decoder includes a separating circuit (100), an error correction decoding circuit (105), an interpolating circuit (110), and a speech reproducing circuit (120, 130, 135, 160, 165, 170). The separating circuit (100) separates a code string of a filter parameter, a code string of a parameter associated with a pitch, and a code string of a parameter associated with an index and a gain of a codebook representing an excitation signal of speech from a received code string. The error correction decoding circuit (105) detects a transmission error, which cannot be corrected, in the received code string. When a transmission error which cannot be corrected is detected, the interpolating circuit (110) interpolates between parameters of past and future proper frames, thereby recovering parameters of a current frame. The speech reproducing circuit (120, 130, 135,160, 165, 170) reproduces a speech signal on the basis of the interpolated parameters and other received codes.

Abstract: This projecting unit operates in accordance with the principle of modulation of polarised light. In light valves for picture modulation of the polarised light passing through, the polariser necessary at the light input in most cases consists of a polarisation foil which, due to the system used, only utilises a maximum of 50% of the incident light. As a replacement for this polarisation foil, an interference-type polariser (50) is used which provides for almost loss-free polarisation of the incident light. Due to the special design of the interference-type polariser (50), the necessary volumes of the modules of the interference-type polariser (50) and of the elements adjacent to it at the light input such as mirror (3), condenser (4) and IR absorption filter (5) are minimised. Due to a special design of an embodiment with IR-transmitting mirror at the light input, a large proportion of the heat content of the light is already filtered out at the interference-type polariser. <IMAGE>

Abstract: A microwave active element (2) is connected in series to a drive circuit of a laser light emitting element (1) and the laser light emitting element is caused to operate as a microwave resonator as viewed from the microwave active element. Laser light from the laser light emitting element is delayed by a delay controller (6) and fed back to the laser light emitting element to control its delay time, thereby controlling the microwave resonance frequency. At the resonance frequency the microwave active element oscillates pulses and provides a microwave signal to its output terminal. 
     The laser light emitting element is driven by a current flowing across the microwave active element and repeatedly emits, at its pulse oscillation frequency, laser light pulses of spectral frequencies which bear higher harmonic relation to the self-oscillation frequency of the microwave active element. By frequency sweeping the resonance frequency of the microwave resonator, the frequency (N·F₀) of the laser light can be frequency swept. With the use of the frequency-swept laser light, it is possible to obtain a light frequency measuring apparatus for measuring the frequency of light to be measured.

Abstract: An improved fiber optic backlighting panel (10) provides uniform and increased background illumination in devices, such as rubber keypads, membrane switches, liquid crystal displays, rigid panels or the like. The fiber optic panel comprises a light source and a layer of optical fibers (24) arranged adjacent each other, which transmit light to different locations throughout the device, thereby providing efficient background illumination relative to the amount of light beamed in. The optical fibers (24) are selectively terminated at these locations by forming a series of angular cuts (30) through the layer of optical fibers with a laser, according to a predetermined geometric zig-zag or sawtooth pattern stored in a computer memory. The zig-zag pattern extends across the entire length and width of the panel (10) such that each optical fiber (24) is cut only once to provide increased and consistent illumination throughout the device. In one specific embodiment, for application in liquid crystal displays, a layer of foam is used to diffuse the light to provide uniform illumination.
