摘要： An oscillator is arranged to generate cycles of an output signal which have a frequency in accordance with the potential across a first capacitor of the oscillator. To increase the frequency of successive cycles of the output signal, a quantum of energy is transferred from a second capacitor, having a small capacitance value with respect to the capacitance value of the first capacitor, to the first capacitor after each cycle of the signal from the oscillator. This successively, with each cycle of the output signal, increases the potential across the first capacitor, so that the succeeding cycle of the signal has a greater frequency than that of the cycle which preceded it.

摘要： In a telephone repeater assembly, a plurality of fasteners is maintained in a self-supporting array by a framework of attached runners. The fasteners are aligned with and joined to a mating part in a pattern which substantially corresponds to the array. Flexibility of the runners permits minor adjustments to the positions of the fasteners in the array to align the fasteners precisely to the pattern on the mating part. Handling the fasteners in such an array facilitates assembly of the fasteners into the mating part. A circuit board is mounted to such part with one side thereof contiguous to the array of fasteners. The board has a plurality of apertures in addition to its mounting holes for the insertion of wide-headed contact screws. The screws are retained by the fasteners. Upon full insertion of the contact screws the head of the screws bridges a gap between two separate conductors on the board and establishes electrical continuity therebetween.

摘要： A wire cutting and insulation stripping apparatus is mounted on a hand-held, portable, wire-wrapping tool and includes a pair of wire cutting blades, a first and second pair of insulation cutting blades and a cylinder such as an air cylinder or solenoid for extending and retracting a rod. In a first embodiment, the wire cutting blades and the first insulation cutting blades are mounted on the cylinder and the second insulation cutting blades are mounted on the rod with the first and second insulation cutting blades directly adjacent each other when the rod is retracted. In operation, an insulated wire is inserted between the wire cutting blades and the first and second insulation cutting blades. This cuts the insulation. The wire cutting blades are then closed to cut the insulated wire and the rod is then extended to displace the second insulation cutting blades away from the first insulation cutting blades. This strips the cut insulation from the insulated wire. In the second embodiment, the first insulation cutting blades are mounted on the rod rather than the second insulation cutting blades and the first and second insulation cutting blades are directly adjacent to each other when the rod is extended. The operation of the second embodiment is essentially the same as the first except that the rod is retracted by the cylinder to strip the insulation from the insulated wire.
摘要翻译：线切割和绝缘剥离装置安装在手持式便携式电线包裹工具上，并且包括一对线切割刀片，第一和第二对绝缘切割刀片和诸如气缸或螺线管的气缸，延伸和缩回杆。在第一实施例中，当切割杆缩回时，线切割刀片和第一绝缘切割刀片安装在圆筒上，第二绝缘切割刀片安装在杆上，第一和第二绝缘切割刀片彼此直接相邻。在操作中，绝缘线插入在线切割刀片与第一和第二绝缘切割刀片之间。这切断绝缘。然后关闭线切割刀片以切割绝缘线，然后延伸杆以使第二绝缘切割刀片离开第一绝缘切割刀片。这会从绝缘电线上剥下绝缘层。在第二实施例中，第一绝缘切割刀片安装在杆而不是第二绝缘切割刀片上，并且当杆延伸时，第一和第二绝缘切割刀片彼此直接相邻。第二实施例的操作基本上与第一实施例相同，除了杆被气缸缩回以从绝缘电线剥离绝缘体。

摘要： To uniformly heat a surface with a source of radiation, the surface having varying thermal heating characteristics in response to irradiation, a filter having radiation absorption characteristics which vary in accordance with the thermal heating characteristics of the surface is positioned between the surface and the source of radiation, such that areas of the filter which have a maximum radiation absorption characteristic overlie areas of the surface which experience maximum thermal heating in response to radiation, and vice versa. Radiation passing through the filter and impinging on the surface is modulated in accordance with the thermal heating characteristics of the surface to uniformly, or isothermally, heat the surface.

摘要： The invention comprises a digital-to-analog converter having a high degree of resolution. An unregulated voltage source supplies current to a network of binary-weighted resistors through a corresponding plurality of selectively actuated switching circuits. A novel parallel-current voltage regulating circuit is connected to a highly accurate reference voltage and regulates the voltage applied to each binary-weighted resistor, after the operation of the associated switching circuit. An 18-bit converter having an accuracy greater than 4 parts per million has been realized.

摘要： Beam lead semiconductor devices are loaded onto an apertured compliant-bonding tape and held thereto with a releasable adhesive. The apertured tape is successively indexed through a loading machine. At one station, small accurately located dots of adhesive are applied to the tape. At a transfer station, integrated-circuit chips are pressed against the tape so that beam leads are secured to the dots of adhesive. Integratedcircuit chips are brought to the transfer station in springbiased holding nests mounted on an indexable turret. The compliant tape is embossed to form protective pockets therein so that when integrated-circuit chips are loaded onto the tape, subsequent winding of the tape onto a reel will not damage the chips.

摘要： A test probe for semiconductor chips is made, starting with a generally flat array of converging sets of leads, whose outer ends are attached to a frame via expansion elements and whose inner ends are attached to each other. In this lead array, there is formed a pyramidal protrusion consisting of the attached inner ends and the portions of the leads nearest thereto. Other lead portions are then embedded in the surface of a plastic frame. Next, the outer ends of the leads are severed from the expansion elements, and the inner ends are severed from each other. The outer lead ends constitute the contacts between the probe and associated external test equipment, while the pyramidally protruding inner lead ends constitute the probe fingers for contacting the semiconductor chips. Preferably, a second protrusion, which provides a pedestal for pyramidal protrusion, is also formed in the lead array. In that case, lead portions forming the pedestal are also embedded in the plastic frame surface. The lead displacements involved in forming the two protrusions are accompanied by compensating movements of the expansion elements, thereby preventing stretching of the leads themselves.
