Title: Commutator for dc mini-motor and method for manufacturing the same
Inventor: KAMIMOTO NOBUAKI
IPC: H02K13/00
Filed: 1978-03-15
Abstract: PURPOSE: To manufacture a commutator having low abrasion brushes and low abrasion brush-sliding layers and stable operation characteristic, in a simple manufacturing precess, by forming the brush-sliding layer from a baking varnish made from a mixtue of carbon pewder and thermosetting resin denatured by a drying oil.  
     CONSTITUTION: Metal layers 2 having a predetermined shape is previded on an insulating plate 4, and a varnish, comprising a mixture of carbon powder and thermosetting resin denatured by a drying oil, is printed on the surface of the metal layers 2, then the varnish is baked at a temperature of 80° to 160° to form the brush-sliding layers 1. In an alternative method, a uniform metal layer 5 is formed on the insulating plate 4, and said varnish is printed on its surface to form the brush-sliding layers 1, then channels 9 are formed by etching away the residual metal layer. Thus, the abrasion of the brush 3 and the brush-sliding layers 1 can be reduced by the action of the resin component, and a commutator capable of stable operation can be obtained because the brush-sliding layers 1 will not be stripped off from the metal layers 2.

Abstract: PURPOSE:To make capacity between a gate and a drain extremely small and to lessen noise and also to make it have high gain up to high frequency by thinning the thickness of a low resistance layer positioned below a drain electrode than that of a low resistance layer positioned below a source electrode. CONSTITUTION:On the main face side of a semiinsulating GaAs substrate 1, an N-type channel layer 2 and an N<+>-type resistance layer 3 are accumulated continuously on the whole face using a usual epitaxial method. As the thickness of the N<+>-type resistance layer 3, it is accumulated from about 0.1mum to about 0.15mum. A source electrode 4 is formed on the N<+>-type resistance layer 3, and also a drain electrode 5 is formed thereon after etching the N<+> type resistance layer 3 by about 0.05mum to about 0.1mum and thinning it than the thickness of the N<+>-type resistance layer 3 below the source electrode 4.
