Title: D/a converter
Inventor: SONE KAZUYA
IPC: H03M1/74
Filed: 1992-02-28
Abstract: PURPOSE:To facilitate circuit integration for the D/A converter by providing a weighting current source having at least two current source circuits to the D/A converter so as to relax the setting accuracy of a current on request. CONSTITUTION:Each of weighting current sources 21-2n consists of two current source circuits D1, D2 of the same current and an analog current A from an output terminal TA when all switches S1-Sn are closed is expressed in equation I. A setting accuracy epsilon of the current I requested to each current source circuit is expressed in equation II. Moreover, when n-sets of the weighting use current sources 21-2n are configured by 2<a> sets of current source circuits of the same current I, an analog current A when all the switches S1-Sn are closed is expressed as 2<a>-nI. The setting accuracy epsilon of the current I requested to each current source circuit is expressed in equation III. Thus, the setting accuracy of the current requested to the current source circuit is relaxed by a multiple of root of number of the current source circuits and the circuit integration of the D/A converter is facilitated.

Abstract: PURPOSE:To use only a pair of bearings to support a carriage by controlling the drive of two orthogonal coils so as to obtain a fixed tilt of the carriage to its moving direction after putting the carriage wound by said two coils into a magnetic field. CONSTITUTION:The 1st and 2nd coils 14 and 15 are wound orthogonally round a carriage 11, and this carriage is supported by a dynamic pressure bearing consisting of a rotary shaft 12 and a housing 13.
