摘要： An image pickup optical system includes, in order from the object side, a front unit having at least one reflecting surface with power that is rotationally asymmetrical, an aperture stop, and a rear unit having at least one reflecting surface with power that is rotationally asymmetrical. In this case, F-numbers in two directions perpendicular to each other on a plane perpendicular to the optical axis are different. Decentration takes place in one of the two directions and the F-number in a direction perpendicular to a decentering direction is smaller than that in the decentering direction. When the F-number in the decentering direction is represented by FNY and the F-number in the direction perpendicular to the decentering direction is represented by FNX, the optical system satisfies the following condition: 1.1

摘要： The invention relates to a method of easily and quantitatively determining the diffraction efficiency of a relief type diffraction optical element, and provides a method of designing an optical system comprising a diffractive optical element using diffraction efficiency as at least one estimation index. The diffractive optical element is a transmission blaze grating constructed of a relief having a sawtooth shape in section. The transmission blaze grating having a side wall substantially vertical to a grating surface. The estimation index is given by a predetermined mathematical expression including at least a phase difference due to a relief discontinuity and shadow effects thereof. The mathematical expression includes as the shadow effects of said discontinuity at least a light attenuation effect dependent on an angle-of-incidence and a light attenuation effect independent on the angle-of incidence in a separate manner.

摘要： A diffractive optical element including a stack of first, second and third optical regions or a stack of first, second, third and fourth optical regions, a first relief pattern formed between the first and second optical regions, and a second relief pattern formed between the second and third or between the third and fourth optical regions. The first and second relief patterns have substantially identical pitch distributions and are substantially aligned in a direction of an optical axis. Depths of the first and second relief patterns are set such that a wavelength dependency of diffraction efficiency can be decreased over a wavelength range to be used. It is possible to manufacture in a simple manner at a low cost a diffractive optical element in which undesired flares and ghosts are suppressed.

摘要： A hydraulic pump including a pressure chamber, a drain passage communicable with the pressure chamber, a delivery port, a discharge path fluidly connecting the pressure chamber with the delivery port, and an orifice disposed in the discharge path. A first flow control valve is provided for variably controlling fluid communication between the pressure chamber and the drain passage in response to a difference between fluid pressures upstream and downstream of the orifice. A second flow control valve is disposed within the discharge path, which is operative to variably control an opening area of the orifice in response to energy of fluid passing through the discharge path. The second flow control valve includes a moveable spool exposed to a fluid pressure within the pressure chamber, a spring biasing the spool in such one direction as to increase the opening area of the orifice, and a spring retainer cooperating with the spool to define a spring chamber accommodating the spring.
