Title: Current control circuit
Inventor: KOYANO ATSUSHI
IPC: H01L21/8222
Filed: 1989-02-03
Abstract: PURPOSE:To always flow a very minute base current from a PNP mirror circuit and to avoid the mirror circuit from being completely turned off by connecting a base of an NPN transistor(TR) in Darlington connection to the PNP mirror circuit. CONSTITUTION:An NPN TR Darlington circuit 3 causing a minute idle current to flow to a PNP mirror circuit 2 is connected to the circuit 2. Thus, a control terminal voltage and a bias current change linearly and the state of a terminal voltage at zero or I=0 is obtained. Since a base start current IB to make a TR2 active is supplied to the base of the TR2 under the condition of terminal voltage =0, bias current =0 and the TR2 turned off via the PNP mirror circuit 1, linear control is attained even at a minute control region of the bias current.

Title: Coating of stator core
Inventor: AZUMA SHIGERU
IPC: H02K15/12
Filed: 1994-01-28
Abstract: PURPOSE:To prevent variation in quality by a method wherein a stator core is dipped in a liquid of insulating coating material and after that, excessive coating material is removed by centrifugal separation and then the stator core is burned at high temperature and then is washed. CONSTITUTION:A laminated stator core is hanged down and dipped in specified melted epoxy resin. After that, it is pulled up and is put in a centrifugal separator to separate excessive epoxy resin. Nextly, the stator core us heated to about 60 deg.C by a heating means such as an oven and is kept at the temperature for about 2 hours for preheating. After that, the temperature is raised to about 200 deg.C, and the stator core is heated at the temperature for about 4 hours. By this process, a coating resin film attached to the whole external face of the stator core and resin which had entered the space between core plates are completely heat-cured and attached so firmly that it cannot be separated. After a motor shaft is passed through a center hole of the stator core, the assembled body of the stator core and the shaft is washed with water. As a result, a complete cating film is formed and therefore variation in quality is prevented.
