The benzylamine derivative represented by the formula below and a pharmaceutically acceptable acid addition salt thereof, and a pharmaceutical containing the derivative or the pharmaceutically acceptable acid addition salt thereof, and a therapeutic or prophylactic agent for pollakiuria or urinary incontinence containing the derivative or the pharmaceutically acceptable acid addition salt thereof are provided. The benzylamine derivative of the present invention and the pharmaceutically acceptable acid addition salt thereof have less possibility of occurrence of side effects than known compounds, and show a better therapeutic effect against pollakiuria or urinary incontinence, so that they can be used as excellent therapeutic or prophylactic agents for pollakiuria or urinary incontinence. 

Benzylamine derivative or pharmaceutically acceptable acid addition salt thereof, and use thereof for medical purposes

An optical pickup including: a light source; a diffractive element; an objective lens; and a photodetector, wherein the diffractive element has first to fourth areas provided with a predetermined periodic structure in each of the areas, the second and third areas have phases of the periodic structures of the second and third areas varied at an angle of about 180 degrees, the first area has a phase of the periodic structure in the first area varied from a phase of the periodic structure in the second area at an angle of about 180 degrees, and the fourth area has a phase of the periodic structure in the fourth area varied from a phase of the periodic structure in the third area at an angle of about 180 degrees. The optical pickup can obtain an excellent tracking error signal and improved amplitude when the objective lens is displaced.

Optical pickup and optical disc apparatus including a multi-section diffractive element

The present invention provides an optical pickup corresponding to plural kinds of optical discs which can be downsized and simplified, and can compensate the spherical aberration. Optical path separation for separating the optical path of a first and a second optical beams as approaching beams to an optical discinto optical paths directed to a first objective lensand a second objective lenscorresponding to the optical beams, optical path combination for combining different optical paths of a first and a second reflected optical beams as returning beams which come in from the first and second objective lenses, and approach-and-return optical path separation for separating the optical path of the approaching beam and the optical path of the returning beam are realized by the beam separation/composition prism. Furthermore, a first collimator lensand a second collimator lensare arranged between the corresponding first and second objective lensesand the beam separation/composition prism
