摘要:
A holographic recording apparatus includes first and second light sources for respectively generating first and second light beams. A mask is located in front of a hologram recording material and has an aperture. Interference fringes are recorded in a hologram cell on the hologram recording material corresponding to the aperture. A movement mechanism supports the hologram recording material masked by the mask and relatively moves the hologram recording material with respect to the mask in predetermined directions so that an interference pattern is formed in an area on the hologram recording material. A spatial frequency changing mechanism changes incident angles of the first and second light beams with respect to the mask.

A magnetic recording medium used for the thermally assisted magnetic recording system which fires a laser beam at a magnetic recording medium to partially heat the medium and applies a magnetic field from the outside to the part heated to lower the coercivity for recording. The magnetic recording medium is configured by a glass substrate on which a heat radiation layer, heat retention layer, intermediate layer, and recording layer are stacked. Further, the heat retention layer is configured by a member having an effective refractive index lower than the effective refractive index of the recording layer and having an temperature diffusion coefficient determined by the specific heat, density, and heat conductivity rate higher than glass and lower than metal. The material with a high temperature diffusion coefficient is used lowered in temperature diffusion coefficient using a porous structure or granular structure.

A dialysis apparatus has a dialysate infusing line. One end of the dialysate infusing line is connected to the dialysate introducing line or the dialysate discharging line. The other end is branched out at a branch point into two flow routes, respectively, a first branch end and a second branch end. The first branch end is connectable to the arterial blood circuit or the venous blood circuit. The second branch end is connectable to the tip end of the arterial blood circuit during the blood-returning process. A dialysate infusing pump is arranged on the dialysate infusing line at a connection-side of the dialysate infusing line relative to the dialysate introducing line or the dialysate discharging line from the branch point. The dialysate infusing pump supplies the dialysate of the dialysate introducing line or the dialysate discharging line to the first branch end and the second branch end.

An object is to provide a photoelectric conversion element having a side surface with different taper angles by conducting etching of a photoelectric conversion layer step-by-step. A pin photodiode has a high response speed compared with a pn photodiode but has a disadvantage of large dark current. One cause of the dark current is considered to be conduction through an etching residue which is generated in etching and deposited on a side surface of the photoelectric conversion layer. Leakage current of the photoelectric conversion element is reduced by forming a structure in which a side surface has two different tapered shapes, which conventionally has a uniform surface, so that the photoelectric conversion layer has a side surface of a p-layer and a side surface of an n-layer, which are not in the same plane.

Disclosed herein is a 3-D image display unit that can be controlled flexibly to protect the user from eyestrain and operated easily. The 3-D image display unit includes measuring means for measuring a display time of a 3-D image, parallax adjusting means for instructing 3-D image forming means to adjust the parallax of the 3-D image. In the case where the 3-D image display time measured by the measuring means exceeds a predetermined time, the parallax adjusting means instructs the 3-D image forming means to reduce the parallax of the 3-D image to be formed, thereby the display means comes to display a 3-D image having a small parallax. The user can thus be protected from eyestrain.
摘要:
In a magnetic recording device, a semiconductor laser (LD) is disposed at a position with a predetermined distance from a swing arm having a slider. The laser beam output from the LD is irradiated, via a beam converter and a mirror, to a spherical aberration lens that generates spherical aberration. The laser beam transmitted through the spherical aberration lens is directed to a light incident opening of the slider at a constant angle (perpendicularly), and then to a position of a recording medium at which information is recorded, thereby performing thermal assist at the magnetic recording time.
