Patent number: 5189507Abstract: The invention provides a technique for interconnecting electronic components in which interconnection wires are bonded to contacts on a first component without the use of a material other than the materials of the contacts and the wires; the wires are then severed to a desired length of between 2d and 20d, where d is the diameter of the wires, and bonded to contacts on the second component by means of a conductive material such as solder. Preferably, solder is provided as pools located in recesses in a layer of insulating material. The invention also provides a bonding head for a wire bonder for bonding the wire to the contact on the first component and for weakening or severing the wire at the desired point.Type: GrantFiled: June 7, 1991Date of Patent: February 23, 1993Assignee: Raychem CorporationInventors: William D. Carlomagno, Dennis E. Cummings, Alexandru S. Gliga

Patent number: 5148005Abstract: Circuit protection devices which comprise a PTC conductive polymer element and a second electrical component which is thermally coupled to the PTC element and which, when a fault causes the current in the circuit to become excessive, generates heat which is transferred to the PTC element, thus reducing the time taken to "trip" the PTC element. The second component is for example a voltage-dependent resistor which is connected in series with the PTC element under the fault conditions and is thus protected from damage. Alternatively, the second component is a thick film resistor which is connected in series with the PTC element.Type: GrantFiled: December 22, 1989Date of Patent: September 15, 1992Assignee: Raychem CorporationInventors: Shou-Mean Fang, David A. Horsma, Guillaume Peronnet, Timothy E. Fahey, Andrew N. Au, William D. Carlomagno

Patent number: 4712721Abstract: Mechanical means and methods for delivery of solder preforms arranged in generally rectilinear patterns and oriented so that the ends of the solder preforms may join two planar surfaces upon the application of heat are disclosed. Several embodiments facilitate the delivery of solder preforms in the forms of posts, clips and rings.Type: GrantFiled: March 17, 1986Date of Patent: December 15, 1987Assignee: Raychem Corp.Inventors: Raymond Noel, William M. Robinson, Gabe Cherian, Thomas H. Clifford, William D. Carlomagno, William M. Deasy, Willie K. Grassauer, David K. Haygood, H. Paul Sherlock, Harry E. White

Patent number: 4685025Abstract: Circuit protection devices which contain PTC conductive polymer elements and which are used in situations in which the device is mounted onto, or itself comprises, a rigid wall which is spaced apart from the PTC element and through which the electrodes pass. The behavior of the device can be adversely affected if the electrodes, which are prevented from moving by the rigid wall, prevent the PTC element from expanding to the extent necessary to provide the desired PTC effect. The invention includes the use of specially designed electrodes which lessen the danger that the PTC element, when it is tripped, is prevented from expanding to the extent necessary for effective operation.Type: GrantFiled: March 14, 1985Date of Patent: August 4, 1987Assignee: Raychem CorporationInventor: William D. Carlomagno

Patent number: 4661305Abstract: An article which in use is heated to an elevated utilization temperature comprises a thermochromic composition, which when heated to a transition temperature, provides a visible color change in less than about 5 seconds. The transition temperature is at least 30.degree. C. greater than the utilization temperature. To place visible indicia on the article, the article is heated to a temperature at least as great as the transistion temperature.Type: GrantFiled: January 15, 1985Date of Patent: April 28, 1987Assignee: Raychem CorporationInventor: William D.

Patent number: 4451965Abstract: An apparatus is provided for installing sleeves onto elongated substrates such as electrical wiring or cable, where the sleeves are slideably arranged on fingers extending from a carrier belt. The apparatus includes a base having a belt path for receiving the carrier belt and a finger guideway for receiving a finger of the carrier belt. Stripping means are slideably mounted on the base for forcing a sleeve from a finger onto a substrate. An indexing element is provided for moving the carrier belt to a position so that a finger having a sleeve arranged thereon is in the finger guideway each time after a sleeve is stripped from a finger. In use of the device, the sleeve can be stripped from a finger into the die in two stages, where an elongate substrate is inserted into the removed portion of the sleeve between the two stages. For installing non-cylindrical sleeves on cylindrical substrates, a die is mounted to the base at a position to receive the sleeve as it is stripped from a finger.Type: GrantFiled: September 20, 1982Date of Patent: June 5, 1984Assignee: Raychem CorporationInventor: William D. Carlomagno
