Title: D/a converter circuit, portable terminal equipment, audio device and display controller
Inventor: MATSUI HIROFUMI
IPC: H03M1/06
Filed: 2002-10-30
Abstract: <P>PROBLEM TO BE SOLVED: To compensate variation in manufacture and to maintain linearity and monotonicity.  <P>SOLUTION: N bit R-2R ladder resistance-type D/A converters are set to be units 11 to 14. First and second reference voltages VR1 and VR2 are inputted to them in common. An adder/subtracter 16 inputs one of digital values D1n to D4n (n=0, 1 and 2) obtained by overlapping offsets whose sum becomes zero with a digital input signal Dn. In that case, the digital value with which the offset having reverse polarity in the same value is overlapped is inputted between units 11 and 12 and units 13 and 14, which become pairs, so that an array of digit numbers of bits become opposite. Thus, non-linearity by a manufacturing inplane inclination on resistors constituting an R-2R ladder resistance network between the units is compensated. Consequently, non-linearity, non-monotonicity and occurrence of glitch due to current fluctuation at the time of MSB switching can be suppressed.  <P>COPYRIGHT: (C)2004,JPO

Filed: 2002-11-06
Abstract: <P>PROBLEM TO BE SOLVED: To solve a problem of conventional devices that lubricating oil is easy to leak to deteriorate sealability because a hole of a seal ring at each end of a ball nut has a spiral groove.  <P>SOLUTION: Fig. a shows a side view of a screw shaft 23, and Fig. b shows a cross section of the screw shaft 23 cut by a plane 42 perpendicular to a center axis 41 as a line b-b cross section. A mark 45 corresponds to an outline of the cut surface as an irregular circle. A hole of the seal ring is set to this irregular circle 45. Since there is no spiral groove in the hole of the seal ring, lubricating oil is less likely to leak. Seal performance can thus be improved in an oil lubrication type ball screw mechanism.  <P>COPYRIGHT: (C)2004,JPO
