Patent number: 7100270Abstract: A method of fabricating printed circuit boards integrating thick film resistor components and thin film circuit portions thereon is disclosed. This is a two-phase process, where the first phase is to create multiple thick film resistors, and the second phase is to create a thin film circuit portion on the substrate with thick film resistors in existence, involving the printing of the electrodes and the resistive coating for the thick film resistors, and the printing of a low temperature passivation layer over the resistors; and the thin film circuit is formed by titanium and copper layers over the substrate, and electroplating of interconnections to form copper plated circuit. The present fabrication process does not require drilling of holes nor electroplating of leads to the resistors, thus the whole process can be automated to a greater extent than with conventional techniques.Type: GrantFiled: September 25, 2003Date of Patent: September 5, 2006Assignee: Tong Hsing Electric Industries Ltd.Inventor: Shao-Pin Ru

Patent number: 7096566Abstract: Magnet wires wound in slots in a lamination stack of a dynamoelectric machine are encapsulated, in whole or in part, with plastic. The plastic may be thermally conductive and have features molded therein that enhance heat transfer. The plastic may stiffen the armature and increase its critical speed. Characteristics of the plastic, its geometry and its distribution may be varied to adjust spinning inertia and resonant frequency of the armature. The magnet wires may be compressed into the slots, by application of iso-static pressure or by the pressure of the plastic being molded around them. Larger magnet wire can then be used which increases the power of the electric motor using the armature having the larger magnet wire. A two or three plate mold may be used to mold the plastic around the armature. Balancing features can be molded in place. The plastic can have a base polymer that is a blend of two or more polymers and various thermally conductive fillings.Type: GrantFiled: July 10, 2003Date of Patent: August 29, 2006Assignee: Black & Decker Inc.Inventors: Hung T.

Patent number: 7093344Abstract: A slack-forming mechanism for stator coils that is able to impart slack of appropriate size to the stator coil without imposing an excessively heavy burden on the coiling machine. The slack-forming mechanism includes a coiling machine attachment jig having a protruding member that passes through a clearance formed between a stator body and connector, and has a top edge positioned higher than a clearance pass-through part of a stator coil. As it is possible to form slack in the stator coil without changing the configuration of the coiling machine, deficiencies in prior art slack-forming mechanisms are overcome such as the difficulty of maintaining uniform slack amounts, and unreliability. Moreover, since design-related restrictions are few, an adequately large slack is imparted to the stator coil to adequately suppress breakage of the stator coil induced by temperature change.Type: GrantFiled: June 27, 2003Date of Patent: August 22, 2006Assignee: Minebea Co., Ltd.Inventors: Taiichi Miya, Naohiko Aoyama

Patent number: 7073247Abstract: A method for metallurgically bonding a stator bar to a coupling to reduce the incidence of leak paths resulting from corrosion. The stator bar comprises strands through which a liquid coolant can flow. Adjacent ends of the strands are received in an interior cavity of the coupling through an opening in the coupling. A joining material is provided on a first portion of the stator bar within the coupling opening and adjacent the ends of the strands. The first portion is heated to melt the joining material. At essentially the same time, a second portion of the stator bar outside the coupling is also heated. Once the joining material is suitably molten, the first portion is allowed to cool while the second portion remains heated, thereby causing the joining material nearest the ends of the strands to solidify first.Type: GrantFiled: April 30, 2003Date of Patent: July 11, 2006Assignee: General Electric CompanyInventors: Raymond Grant Rowe, Alan M. Iverson

Patent number: 7051420Abstract: An armature for a brush commutated electric motor having a distributed coil winding arrangement for reducing brush arcing and electromagnetic interference (EMI). The winding pattern involves segmenting each coil into first and second subcoil portions with differing pluralities of turns. Each subcoil portion is wound around separate pairs of spaced apart slots of a lamination stack. Adjacent coils are wound such that one subcoil portion of each is wound in a common slot to therefore form an overlapping arrangement of each pair of adjacently coils. The winding pattern serves to “shift” the resultant magnetic axes of each coil in such a manner so as to significantly reduce brush arcing and the EMI resulting therefrom. The reduction in EMI is sufficient to eliminate the need for EMI reducing components, such as chokes, which have typically been required to maintain EMI to acceptably low levels.Type: GrantFiled: April 1, 2003Date of Patent: May 30, 2006Assignee: Black & Decker Inc.Inventor: Ren Hong Wang
