Title: Power supply circuit
Inventor: YASUMURA MASAYUKI
IPC: H02M7/217
Filed: 1996-12-27
Abstract: PROBLEM TO BE SOLVED: To dispense with the alteration of the design of a power supply circuit and to facilitate ensurance of the lower limit of its regulation range and setting of a high power factor to it, by reducing its ripple voltage components. SOLUTION: An AC voltage is generated in a secondary winding N2 of a converter transformer CVT, by the switching operation of a current-resonance type converter for intermitting the charging current of a smoothing capacitor Ci in order to improve a power factor. This AC voltage is rectified and smoothed to give a DC voltage V3 in the output of a power-factor improving circuit 1. This DC voltage V3 is superimposed on the voltage across both terminals of the smoothing capacitor Ci to feed the obtained voltage to a switching power supply portion 2 as a rectified and smoothed voltage Ei. Thereby, the ripple level of the rectified and smoothed voltage Ei is made equal to the one of a power supply circuit obtained when the power-factor improving circuit 1 is omitted.

Abstract: PURPOSE:To improve the correction precision of the distance error in a long- distance linear travel. CONSTITUTION:The estimated position is stored by a travel locus memory means 43, and a corner detection failure is judged by a corner matching means 44 basing on the corners and corresponding nodes detected in a travel locus. The distance error is calculated by a distance error calculating means 46 in consideration of the corner detection failure judged result and the width of the road. The obtained error data are accumulated in a distance error memory means 47, the average value of the accumulated error data is obtained by a correction quantity calculating means 48 after a long-distance linear travel from the true corner while the accumulated data become a fixed quantity, this average value is used as the correction value for the accumulated error in the linear travel, and the displayed present position is corrected basing on the correction value.

Title: Detecting method of polarity of piezoelectric crystal element
Inventor: KOIDE AKIRA
IPC: G01N21/84
Filed: 1992-12-28
Abstract: PURPOSE:To detect the polarity of a piezoelectric crystal element simply at low costs by making a designated polarized face of the piezoelectric crystal element more rough than the other face. CONSTITUTION:Both surfaces of a piezoelectric crystal element represented by lithium niobate (LiNbO3; LN), lithium tantalate (LiTaO3; LT), rock crystal, lead titanate (PbTiO3), titanium zirconate (Pb(TiZr3)O3; PZT) and the like are made rough by a lapping/polishing method. One is kept rough as it is, while the opposite surface is mirror-finished by a mirror polishing method to be used as an electrode face. The particle size of an abrasive grain or a whetstone used when the surface are made rough is preferably about #320-800 (average particle size of 62-1.0mum). The rough polished surface is distinguishable from the mirror-finished opposite surface by eyes. Even when the same metal is used to provide electrodes or the like, the surfaces can be distinguished, and the polarity of the crystal element of each surface can be distinguished. When inexpensive aluminum is used, the manufacturing cost is reduced.
