Abstract: PROBLEM TO BE SOLVED: To provide an optical head device having high light utilization efficiency, easily positioned and capable of preventing the effect of variation per hour such as a positional shift after manufacturing. SOLUTION: A slab waveguide 2 guides a light from a light source 4. A waveguide mirror 5 converges the light from the light source 4, wave-guided by the slab waveguide 2, on an end surface 1A opposite the recording medium 7 of the slab waveguide 2.

The slab waveguide 2, the waveguide mirror 5, the photodetector 6 and the photocoupler are formed on the same semiconductor substrate in a monolithic manner. Since by using the slab waveguide 2, an optical path from the light source 4 to a condenser unit and an optical path to the photodetector 6 of a scattered light made incident from the end surface are set as the same waveguide, the light modulated by the record medium is efficiently guided to the photodetector 6.

Filed: 1995-03-09
Abstract: PURPOSE: To form a rough surface on the surface of an electrophotographic photoreceptor base body by means of a simple method by jetting dry ice grains onto the surface of the base body. CONSTITUTION: In a base body 10 formed into a cylinder, both ends are fixed by means of jigs 11, 12. From an injection device 13 arranged on one side of the base body 10, dry ice grains 15 are jetted from an injection port 14 toward the base body 10. The injection is carried out for several seconds, while the base body 10 is rotated with the jigs 11, 12, so that the dry ice grains 15 evenly collide against the whole circumference surface of the base body 10. By means of shocks in this process, multiple fine recesses are generated on the surface of the base body 10, and a rough face is formed. If the injection device 13 is moved in the vertical direction during the injection of the dry ice grains 15, the rough face can be formed more uniformly. In this process, an environment controller may be arranged so as to control the surface temperature of the base body 10 for forming the rough face under a fixed environment.
