Title: Dynamic pressure bearing motor and its manufacture
Inventor: SUZUKI MITSUO
IPC: H02K21/14
Filed: 1995-07-17
Abstract: PROBLEM TO BE SOLVED: To protect coils and Hall elements from the influence of the heat for shrinkage fit even if the coils and the Hall elements are attached to a main housing to which the fixed shaft of a dynamic pressure bearing is fixed by sharinkage fit. SOLUTION: After a fixed shaft 7 is fitted to the opening hole 6 of a main housing 32 by shrinkage fit, coils 13 and Hall elements 15-17 are attached to the main housing 32. As the heat for shrinkage fit does not have the influence upon the coils 13, etc., a winding frame 34 for the coils 13 can be made of resin to realize a coreless motor. By attaching the coils 13, etc., and the fixed shaft 7 to one main housing 32, the productivity and the assembly precision can be improved.

Abstract: PURPOSE:To reduce an effect of floating capacity due to an input switch of a multiplexer and to eliminate the interference between the input voltage quantities, by selecting the common potential of a sample holding circuit prior to the selection of the output of the sample holding circuit. CONSTITUTION:When a multiplexer MPX is switched to the input of an input channel CH2, the floating capacity C0 is cut off from the output of a sample holding circuit SH1 and then connected to the OV potential connected to the channel CH2. Then the electric charge which is charged to the capacity C0 is discharged, and the voltage of the capacity C0 is instantaneously set at OV. When the MPX is switched to the input of an input channel CH3, the OV of the channel CH2 is cut off. Then the output of a sample holding circuit SH2 is turned into an output V0 of the MPX. As a result, the electric charge stored to the capacity C0 never flows to the holding capacitors C1-Cn.
