Patent EP-0435025-A2 (EP)
Inventor: ZIEGLER HANS-PETER DIPL-ING
IPC: B29C45/17
Filed: 1990-12-04
Abstract: In the case of apparatuses of this type, there is the disadvantage that the fitting of the needle-shaped injection nozzle, by which the gas is introduced into the mould cavity, is problematical, since the previously injected polymer melt can very quickly solidify like a skin in the outer boundary region due to cooling, so that a reliable penetration of the injection nozzle or piercing of the skin already formed is not ensured. Furthermore, a lifting-off of the polymer melt in the piercing region of the gas injection nozzle can occur, with loss of gas. It is the aim of the invention to avoid these disadvantages and to achieve a reliable insertion of the needle without damage and without the risk of boundary zones of already fed-in polymer melt lifting off, as a result of which accurate metering of the quantity of gas fed in is achieved in the mass production of hollow plastic bodies. This object is achieved by the end (17) of the gas injection nozzle (8) which faces the mould cavity (3) protruding freely until approximately in the centre of the part of the mould cavity (3) assigned to the gas injection nozzle. The invention is used in particular in the mass production of hollow plastic bodies which consist with preference of partly crystalline polymers, for example polyamide. …<IMAGE>…

Abstract: An optical pickup head comprises a hybrid device having a laser source (1) and a photodetector unit (5) which are housed in a single package (2), a focussing lens (8) for receiving a laser beam emitted from the laser source and focussing the laser beam on an optical disk (4) serving as an optical memory medium, and a holographic optical element (6) for receiving a return optical beam reflected and diffracted at the optical disk and regenerat­ing diffraction beams (81-84) directed to the photo­detector unit. In the package, the photodetector unit is disposed closer to the bottom of the package than a light emitting point (10) of the source to make the upper surface of the photodetector unit substantially flush with the top of connection terminals (101) of the package, thereby improving working efficiency of bonding work for wiring between the photodetector unit and the connection terminals and compactness and reliability of the optical pickup head. Such a disposition of the photodetector unit is allowed by using the holographic optical element with a substantial concave lens function for the hologram region at which diffraction beams (81, 82) used for focussing error signal detection are generated.

Abstract: A light-emitting diode is mounted in the bottom of a cavity in a metal lead and the assembly is potted in a transparent plastic material. The walls of the cavity surround the sides of the light-emitting diode in sufficiently close proximity to effectively shield the light-emitting diode from thermal expansion stresses from the plastic potting material which would induce light output degradation. Such a cavity may be a right-­circular cylinder with a diameter less than 75 micro-­meters greater than the largest transverse dimension of the light-emitting diode. The front face of the light-­emitting diode may be flush or beneath the face of the metal lead for minimizing stress. The cavity may be deep enough that the front face of the light-emitting diode is closer to the bottom of the cavity than to its open end. The front face may protrude beyond the open end of the cavity and be surrounded by a reflective surface. The edges of the front face of the light-­emitting diode may be beveled for minimizing stress.

Abstract: An autoclave or other equipment has a counter 20 provided by an EEPROM for counting the number of times the autoclave has been used. The EEPROM has a first set of ten registers R4 to R13 which contain the unit value of the count together with a fault code associated with the last use of the autoclave. Two further registers R3 and R2 contain the hundreds and tens, and the ten thousands and thousands value of the count. The tens value in one of the further registers R3 is used to determine in which of the registers R4 to R13 of the first set the units value is stored, so that, each of the registers in the first set is only written into ten times for every hundred counts, thereby extending the life of the EEPROM. Another register R1 in the EEPROM contains information about the nature of the autoclave.

Abstract: The brightness of an X-ray video image during fluorography is maintained at a substantially constant level by a control circuit which varies the X-ray dose in relation to changes in the average brightness of the X-ray image. Selected picture elements of the image which lie within a defined region in the image and which have a brightness above a given level are used to derive the average X-ray image brightness. The brightness of the selected picture elements are summed and the number of such picture elements counted. The summation of the brightness and the picture element count are both scaled by a factor of 2 n  to reduce the size of the numbers and the complexity of the averaging circuitry. The scaled brightness summation is divided by the scaled picture element count and the result is stored as the average X-ray image brightness.

Abstract: An enhanced fixed function video display terminal having various features for the efficient transmission of data streams. The video display terminal may have a memory for storing substantially more characters than can be dis­played to the operator on the display screen width and length. This permits manipulation of data at document page boundaries, scrolling, etc. One or more extended attribute buffers (312, 314) are added to enable charac­ters to be displayed in a variety of fonts, colors, etc. The data stream from the host computer to the display terminal and from the display terminal to the host comput­er contains data characters and attribute characters which are interleaved for efficiency in input/output program­ming. When receiving data, the display terminal has the capability of parsing the data stream into data or at­tribute characters and adding pad characters to completely fill the display buffers. Similarly, the display terminal interleaves data and attribute characters and compacts the data stream by stripping pad characters when sending data back to the host computer.

Abstract: An electrical circuit (30) corrects for the presence of noise current and current drift in the currents developed by each current source transistor Q₀, Q₁, Q₂, Q₃, ... Q n  in a current source array. The electrical circuit corrects for the presence of noise current and current drift by simultaneously inducing in each current source correction currents whose values sum to cancel the current drift and noise. A noise suppression circuit includes an amplifier (12) having an open loop gain, A v , which is configured to adjust the magnitudes of the multiple currents in response to the introduction of a noise current, i δ , in any one of the currents. The adjustment substantially cancels i δ  and thereby substantially reduces the presence of i δ  in the output current. The presence of i δ  in the output signal is substantially equal to i δ /(1 + A v ).

Abstract: In order to avoid input current surges when plugging in or switching on the switched-mode power supply, or when recharging the switched-mode power supply after a failure in the input mains AC voltage (AC) or after an interruption of the same during operation, the input capacitor (CE) is relocated to the output of the switched-mode power supply. At the same time, a voltage regulator (SPR) is used, which is known per se, is rapidly pulsed as a function of the instantaneous value of the sinusoidal input mains AC voltage supplied to the switched-mode power supply, operates in accordance with the step-down controller principle and is constructed such that an input current which is similar to a sine-wave is forced to be drawn, such that active current limiting takes place and such that there is mains isolation between its input and output. <IMAGE>

Abstract: An environment-friendly aqueous slip and mould-release agent for the manufacture of tyres and other rubber articles and a process for the moulding and vulcanization of tyres and other rubber articles are described. The aqueous slip and mould- release agent contains 0.5 to 6 wt.-% polytetrafluoroethylene, 20 to 40 wt.-% mineral fillers and at least 40 wt.-% water. It is sprayed onto the inside of the tyre blank prior to the moulding and vulcanization, so that the water contained therein evaporates, accompanied by development of a slip and release agent film. Apart from the environment-friendliness and good release effect, the new slip and mould-release agent leads, despite the high water content, to a quick evaporation of the water and thus a rapid development, desired in industrial operations, of the slip and release agent film. The excellent effectiveness of the slip and mould-release agent according to the invention results in a substantial prolongation of the life of the heating membrane used for the moulding and vulcanization.

Abstract: A biphase-mark coded digital audio signal comprising short and long pulses (IEC 958) is decoded despite substantial variation of sample rate but without a separate synchronisation or timing signal and without a phase locked loop. The pulse lengths are measured (14) and then compared (22,20) with two thresholds. One (22) is a variable threshold derived by generator (26) as 1.5 times the average length of the short pulses, this average being stored in register (28). This will normally be adequate to discriminate the short and long pulses. The second comparison (20) is with a fixed value which is lower than 1.5 times the pulse length at the highest input frequency. When the comparators disagree irreconcilably in their determination, the resultant of the second comparison is used instead of the first. This allows the system to respond quickly to start-up or sudden change in input data rate.
