IPC: G02B27/28
Filed: 1994-04-21
Abstract: PURPOSE:To improve the utilization efficiency of the luminous flux of a light source of a polarizing illuminator and to make the cross-sectional light intensity of the polarized illuminous flux uniform. CONSTITUTION:The illuminator includes a light emitting source 1, a rotating body reflection mirror 2, a polarization beam splitter 6, plural mirror members 8, 9 and 10 and mixing means 12 and 13. The mirror 2 houses the source 1 and forwardly radiates a light source luminous flux 4 which includes a central shadow section 3. The splitter 6 splits the flux 4 into mutually orthogonal and linearly polarized components and one of the components is emitted as a polarized luminous flux 7. The plural members 8, 9 and 10 repeatedly reflect the remained other linearly polarized component and convert the component to a return flux 11 whose polarization is canceled. The means 12 and 13 join the flux 11 to the section 3 of the flux 4.

Title: Method and apparatus for making letterpress printing plate* and printing plate made thereby
Inventor: YOHANESU KORUNERISU SUHOUTE
IPC: G03F7/18
Filed: 1979-07-02
Abstract: A process is provided for making a relief printing form which is at least partially cylindrical from a liquid photopolymerizable molding material. In accordance with the process, a molding material is spread over the internal surface of the cylindrical wall by centrifugal force and hardened in the desired places with ultraviolet light to form an image corresponding to a printing design. The nonhardened portions of the molding material are then removed. The cylindrical wall is a transparent cylindrical tube. An exchangeable image-bearing film is placed on the inside of the tube. Photopolymerizing radiation of the printing form material is effected during rotation of the transparent cylindrial tube. An exchangeable image-bearing film is placed on the inside of the tube. Photopolymerizing radiation of the printing form material is effected during rotation of the transparent cylinder by means of one or more radiation sources distributed around the circumference of the transparent cylinder. The rays act on the molding material via the wall of the transparent cylinder and the image-bearing film. The radiation for hardening the printing form takes place in a continuous operation following the application of the molding material to the cylindrical wall by centrifugal force.

Title: Tunable semiconductor laser
Inventor: SUZUKI AKIRA
IPC: H01S5/00
Filed: 1992-03-06
Abstract: PURPOSE:To obtain a tunable semiconductor laser of a narrow oscillation spectral line width even at a tunable time. CONSTITUTION:When a strain is introduced in quantum wells 71 of an active layer 7, an oscillation takes place in TM polarized light because a phototransition energy between light holes and electrodes is lower than a phototransition energy between heavy holes and electrons. At this time, if a quantum well structure is introduced in a carrier injected layer 8 to contribute to control of an oscillation wavelength, the vibration of carriers due to the photoelectric field of the TM polarized light is quantized in the direction vertical to a substrate. As a result, the effective mass of the carriers to contribute to a plasma effect is effectively increased because the spread of an oscillation spectral line width is inversely proportional to the square of the effective mass of the carriers. Accordingly, a tunable semiconductor laser of a narrow oscillation spectral line width is obtained at a tunable time.
