Patent EP-0267379-A2 (EP)
Inventor: HOOPER DONALD F
IPC: G06F9/44
Filed: 1987-08-26
Abstract: In a circuit design synthesis procedure in which the point­ers are added to the data base to permit a path through the cir­cuit to be followed, a qualified object is defined to be a data object that permits access expressed by a sequence (or chain) of access forms strung together. A mechanism is defined that per­mits access of any other object in the data base. Access forms are strung together in a given format. This structure provides an easily understandable access form and it is defined in the rule grammar. This access form can be parsed in the synthesis procedure into a nest of (LISP) program functions, which, when evaluated, will return an object in the data base. This access chain is used in the antecedent portion of the rule structure for the purpose of modifying the target objects. This access struc­ture permits the synthesis rules to make decisions on such parameters as timing, cell size, power, wire loading, model names, etc. The rules of the synthesis procedure can be written in such a manner as to be similar to a circuit designer's rules. In addition to the access of objects, this chained access struc­ture also permits tagging (or marking) a subset intermediate ob­jects to be temporarily saved for use by the synthesis rules. This additional capability provides the ability to sort and par­tition sets of objects based on attributes and permits a synthe­sis procedure capable of using abstract tradeoffs.

Abstract: A surface-mount power resistor may be fabricated using a power resistor of conventional design as its core. A conventional resistor is reworked so as to flatten its leads from a point near their emergence from the generally tubular body of the resistor to the ends of the leads. The reworked resistor is then encapsulated from a point on the flattened portion of one lead to a corresponding point on the other lead, with the resulting mold being shaped as to have at least two opposing flat surfaces. The ribbon-shaped portions of the leads which exit from the molded body are then shaped as desired to afford the finished product. Similar surface-mount electrical components may be fabricated for any component with axial leads.

Abstract: This invention relates to poly(acetylene) films having localised zones of a material other than poly(acetylene) with modified optical and electrical properties. The films are formed by selectively irradiating discrete areas of a film of a precursor polymer followed by heating of the irradiated precursor polymer to transform the non-irradiated areas into poly(acetylene). The resultant product has localised zones of modified electrical and optical properties which are useful in the semiconductor industries and in optical devices.

Abstract: A continuous process is described for the production of a substantially acid free dialkyl maleate, for example diethyl maleate, from a feed stream containing a major amount of dialkyl maleate and a minor amount of the corresponding monoalkyl maleate. This comprises continuously distilling the feed stream in a primary distillation zone, which can comprise a single distillation column or a series of distillation columns connected in series, so as to give (i) a bottom fraction containing monoalkyl maleate and dialkyl maleate in admixture, (ii) a vaporous fraction comprising alkanol, and (iii) an intermediate fraction that is substantially free from alkanol and comprises a major proportion of diethyl maleate and a minor proportion of maleic anhydride. The intermediate fraction (iii) is redistilled in a secondary distillation zone to yield (i) an overhead fraction containing maleic anhydride and (ii) a bottom fraction containing substantially acid free dialkyl maleate. The vaporous stream can be condensed to recover alkanol for recycle to a dialkyl maleate production facility.

Abstract: An apparatus for distributing sample liquids (12) from source test tubes (10) into destination test tubes. It has distribution tips (3) and air-supply devices (23) for supplying air to the tips (3) at a low rate. The tips (3) are lowered into the source tubes (10), while air is flowing from the devices (23) and through the tips (3). The moment the tips (3) reach the surface levels of the liquids (12) contained in the source tubes (10), the air pressure changes. When this change is detected, the tips (3) start sucking the liquids (12) from the source tubes (10). An apparatus similar to the above-mentioned one. It has distribution units (31 ∼ 35) each having a tip (3), a lever (60) having a slit (61), and pins (51 ∼ 54) projecting from the units (31 ∼ 35) and inserted in the slit (61). The lever (60) is rotated, changing the interval between the distribu­tion units (31 ∼ 35) to the interval between the source or the destination tubes held in a rack. A similar apparatus which has distribution tips (3) and a tray (81). The tray (81) is kept away from below the tips (3) while the sample liquids (12) are being sucked into the tips (3) from the source tubes (10) or being distri­buted from the tips (3) into the destination tubes, and is placed below the tips (3) while the tips (3) are being moved. A similar apparatus which has distribution units (31 ∼ 35) each having a tip (3), and a jig (100) having cut-outs (101 ∼ 105).
