摘要:
An illumination optical system has a light source, an integrator for making the intensity distribution of the light from the light source even, and a relay optical system for imaging the light from the integrator on a plane conjugate with the exit surface of the integrator. The relay optical system includes a rear lens unit of which the refractive power is asymmetrical in one direction so that the plane on which the light is imaged is inclined relative to the optical axis of the relay optical system. This makes it possible to direct light to an inclined surface with an even intensity distribution and with minimum loss of the illumination light.
摘要:
To realize an electrophotographic photoreceptor excellent in abrasion resistance, the photosensitive layer of the photoreceptor comprises a polyester resin containing a repeating structural unit represented by the formula (1) and a hydrazone compound. (In the formula (1), Ar1 to Ar4 each represents, independently of each other, an arylene group which may have a substituent. X1 represents a bivalent group (including a single bond) and X2 represents a bivalent group (including a single bond) with 3 or less atoms.)

The present invention provides HIDE1 as novel monocyte markers. Since HIDE1 are membrane proteins, monocytes can be specifically detected by using antibodies that bind to HIDE1. Further, HIDE1-positive monocytes can also be collected from peripheral blood or the like using a cell sorter, magnet, or such. Monocytes that can be prepared based on the present invention are useful in cell immunotherapy.
摘要:
A zoom lens system has, in order from an enlargement side, a first lens unit having negative optical power, a second lens unit having positive optical power, a third lens unit having positive optical power, a fourth lens unit having negative optical power, including an aperture stop, a fifth lens unit having positive or negative optical power, and a sixth lens unit having positive optical power. Zooming is achieved by varying the first to fifth variable distances between the lens units. The third and fifth lens units move from the enlargement side to the reduction side during zooming from the telephoto end to the wide-angle end. The zoom lens system is substantially telecentric toward the reduction side.
