Patent EP-0297844-A2 (EP)
Inventor: KNUDSON ORLIN B C O MINNESOTA
IPC: G09G3/12
Filed: 1988-06-29
Abstract: An exponential multiplication power supply is described which is comprised of a plurality of stages each having the ability to store energy and each having a plurality of states, including at least a store state and a stack state. The plurality of stages are arranged in a network such that an input stage in the network is connected to receive a voltage fron an external power source and all subsequent stages are connected to at least one other stage for receiving voltage from and through the other stages. A control mechanism is attached to the network stages and operates to place these stages in a repeating sequence of states such that at least one of the stages receives a voltage which is the sum of the voltages stored in at least two other stages. When a stage is receiving voltage or holding voltage it is said to be in the store state, and when a stage is combined with other stages to present an increased voltage, it is said to be placed in the stack state. This exponential voltage nultiplication power supply is applied to the production of high voltage for exciting electroluminescent panels. The application of this power supply includes compensation circuitry to vary the excitation in response to varying characteristics of the electroluminescent panel.

Abstract: A thin film deposition process comprises the steps of providing a first target area on a magnetron electrode, sputtering particles from said area so that they fall onto a heated substrate body for forming the required deposit, simultaneously operating a sputtering gun such that further particles are dislodged from a second target area and directed towards the substrate, the two resulting particle plasmas mixing at the substrate surface such that a deposit of a predetermined chemical composition is produced. 
     This allows a multicomponent material such as a PLZT ceramic to be deposited without a change in composition due to different volatilities etc. of the components.

Abstract: There is disclosed a method of producing a transition metal pattern on a glass or glass-ceramic substrate by selective exudation of a transition metal from a glass substrate containing the metal as an oxide. The selective exudation is effected by applying an intense, well-focused source of energy to a glass in a pattern corresponding to the desired metal pattern. This develops localized heating, and thereby causes corresponding localized metal exudation from the glass. The metal pattern may be rendered electroconductive, and may constitute a pattern of interconnecting lines for microcircuitry. 
     There is also disclosed a family of low dielectric, copper-exuding, boroaluminosilicate glasses particularly adapted to use in forming substrates for electronic devices such as integrated circuits. The glasses are capable of exuding copper oxide, have a coefficient of thermal expansion of 30 - 35 x 10⁻⁷ at 300°C, a dielectric constant not over 5.0 at 100 KHz, a loss tangent not over 0.003 at 100 KHz and consist essentially, in percent by weight, of 56 - 64% SiO₂, 18 - 25% B₂O₃, 3-11% Al₂O₃, 0-2% CaO, 0 - 2% Li₂O, 0 - 1% K₂O, and Li₂O + K₂O + CaO being 1.5 - 3% and 1 - 20% CuO.

Abstract: A multiplex transmission system, in which a plurality of nodes are coupled together through a transmission path, and a node as a transmission node transmits a frame of data including a data area containing transmission data, to other nodes as reception nodes through the transmission path. The frame of data includes a data valid/invalid area having the same bit length as the data area and indicating, bit by bit, the validness/invalidness of the data carried by the corresponding bits in the data area. The system need not be modified depending on the model and grade of vehicles, and can be used widely and applied to various options by the use of a signal allocation system common to different models and grades of vehicles. Those bits in the data area which correspond to the bits in the data valid/invalid area indicative of data invalidness may have values thereof set to a fixed value, so that the reception node judges the transmission node to be defective when a bit of the data valid/invalid area of the received frame and the corresponding bit of the data area of the received frame make a combination of specific values.

Abstract: An improved TDMA radiotelephone cellular communication system (122, 115, 199) employs an improved cell site scan monitoring technique. The technique includes monitoring radiotelephone calls, and tracking and recording their signal qualities. The records are used to maintain and determine which frequencies and which time partitions at the base site equipment (115, 119) are being utilized for radiotelephone communication. When a new call assignment is required at a cell site (115 or 119), it is assigned to a time partition of a base site equipment frequency in a frequency prioritized manner such that radiotelephone calls are concentrated within each frequency so as to reduce the number of frequencies carrying radiotelephone calls.

Abstract: In the case of a plug, the engagement position of the plug part in the complementary socket part is locked by means of a U-shaped spring bracket. Bent end sections of the bracket limbs are used for gripping behind latching tabs of the inserted plug part and grip through perforations in a sleeve-shaped housing of the socket part, where the spring bracket is mounted. The unlocking of the plug part takes place by spreading the bracket limbs which moves the latching sections out of the insertion path of the plug part. In order to carry this out conveniently and also in unfavourable spatial conditions it is proposed that the spring bracket be used as a lever over its complete length, which is pivoted to unlock its latching sections. The pivoting takes place in the plug movement direction of the plug and socket part. In this case, the bracket limbs engage on their inner side facing the housing base underneath wedges which are used for spreading the bracket limbs during pivoting. Expediently, these wedges consist of obliquely running walls of an outer slot which is used for holding the bracket limbs of the spring bracket.

Abstract: The coating method contains a spraying step in which a paint is sprayed at least on a coating substrate extending in an upward and downward direction to a film thickness thicker than causing sags of the sprayed paint. The coating substrate on which the paint is sprayed is rotated about the horizontal axis while the sprayed paint is dried until it does not sag any more. 
     The coating apparatus includes a carriage conveying the coating substrate arranged to run along the conveying direction, and the carriage is provided with a supporting base for supporting the coating substrate rotatively about the horizontal axis. One embodiment for rotating the substrate supported by the supporting base is a spring that is disposed on the carriage to rotate the substrate by means of a restoring force produced by the spring. On the passage for conveying the carriage is disposed a force storing mechanism for storing the restoring force in the spring that released the restoring force. 
     Another embodiment therefor is a combination of a chain disposed along the conveying passage for the carriage with a sprocket disposed on the carriage. The sprocket is engageable with the chain and operatively coupled to the coating substrate. By disposing the chain in a fixed manner, on the one hand, the substrate is caused to rotate as the carriage is being conveyed. By dividing the chain, on the other, the substrate is caused to rotate while theconveyance of the carriage is suspended.
