Title: Laser beam generator
Inventor: SASAKI TAKATOMO
IPC: G02F1/355
Filed: 1999-01-29
Abstract: PROBLEM TO BE SOLVED: To provide a laser beam generator which is simplified in constitution, small in size and capable of generating a UV laser beam as well by providing the generator with a specific nonlinear optical crystal element and making it possible to execute laser oscillation and the generation of second harmonic and third harmonic laser beams with this element. SOLUTION: The generation of the third harmonic under non-critical phase matching conditions at room temperature is embodied with a GdxY1-xCOB, i.e., GdxY1-xCa4O(BO3)3 crystal substituted with the Gd portion. The similar thing is made possible even in the second harmonic generation as the nonlinear optical crystal of the constitution described above. In such a case, the second harmonic may be outputted as well under nearly the non-critical phase matching conditions in the same direction as the direction where the non-critical phase matching conditions of the third harmonic are satisfied. Namely, the laser oscillation to the generation of the UV light are executed by doping a laser medium (Yb: ytterbium or Nd: neodymium) to the crystal and further, adding the function of the laser oscillation.

Filed: 1992-02-10
Abstract: PURPOSE:To reduce impact caused at the time when a cleaning blade is reached and to restrain degradation of the image by constructing the device so that a position where the seam of the photosensitive body is brought into contact with the cleaning blade, is relatively shifted with the movement of the photosensitive body. CONSTITUTION:A belt-shape photosensitive body 1 and an intermediate transfer body are each driven by driving sources. The seam 1a of the photosensitive body 1 is constructed so as not to be in parallel to a line orthogonally crossed with the moving direction of the photosensitive body 1, so therefore, the seam la of the photosensitive body 1 is gradually brought into contact with the cleaning blade 8a. In other words, the position where the seam 1a of the photosensitive body 1 is brought into contact with the cleaning blade 8a, is relatively shifted with the move of the photosensitive body 1, and as a result, the impact caused by difference of surface level is reduced. Thus, revolving speed of the photosensitive body 1 is always kept constant, irregularities in the image are reduced and the degradation of image can be satisfactorily restrained.

Title: Manufacture of silver halide emulsion
Inventor: MATSUZAKA MASASHI
IPC: G03C1/035
Filed: 1990-02-02
Abstract: PURPOSE:To suppress fogging in reservation with the lapse of time by specifying the pH of an ammonium silver nitride solution in use. CONSTITUTION:The pH of the ammonium silver nitride solution is set to <=10.5. When the ammonia silver nitride solution is prepared, ammonia more than an equivalent is added to silver nitride to generate a silver-ammonia complex, but the pH is generally >=11 because of the silver group dissociation of the ammonia. Consequently, the pH is decreased to <=10.5 by adding an acid such as nitric acid to prepare an ammonium silver nitride solution which is different in pH. Thus, the ammonium silver nitride solution which is decreased in pH is used. Consequently, manufacture conditions which reduce fogging are obtained.

Abstract: PURPOSE:To separate and receive the orthogonal polarization component of incident light by providing a multiple quantum well structure, where the light absorbing layer in a waveguide into is separated into two or more functional regions, and the light absorbing layer in at least one functional region has the absorbing characteristic depending on the polarization plane of the light. CONSTITUTION:An n-type first clad layer 22 is formed on a substrate 21. A multiple quantum well absorbing layer 23 and a bulk absorbing layer 24 constituting a waveguide, which is to become a light absorbing layer, are formed on the first clad layer 22. Incident light is propagated from right to left in the waveguide. The light of a TE polarization component is absorbed by the multiple quantum well absorbing layer 23 and does not reach the waveguide of the bulk absorbing layer. Only the light of a TM polarization component is a absorbed by the bulk absorbing layer 24. Therefore, the intensities of the TE polarization component and the TM polarization component can be independently measured by monitoring photocurrents I1 and I2 with an a ammeter inserted between an N-side electrode 28 and P-side electrodes 27a and 27b. Thus, the orthogonal polarization components of the incident light can be separated and received.
