Abstract: PURPOSE:To reduce the noise of laser by arranging a Farady rotatary element having 45 deg. of Farady rotatary angle in an optical path of a single mode laser and a polarized beam splitter so as to apply only the linearly polarized light in orthogonal direction of the laser as a return light. CONSTITUTION:A semiconductor laser 7 of an optical head is arranged at an angle of 45 deg. with respect to orthogonal X, Y axes, the emitted light is collimated by a collimate lens 8, rotated by 45 deg. by a Farady rotatary element 9 having an angle of 45 deg. and the result is radiated in a polarized face of the polarized beam splitter 10. The transmitted light of the splitter 10 is subject to circularly polarization by a 1/4 wavelength plate 11, and the light focused by the objective lens 12 is radiated in the optical disk 13. The circularly polarized light from the disk 13 whose rotating direction is opposite is converted into a linearly polarized light in parallel with the Y axis by the wavelength plate 11, the elliptically polarized light is radiated from the wavelength plate 11 and the result is made incident in the splitter 10. Then the linearly polarized light in parallel with the X axis by the splitter 10 is rotated further at the element 9 by 45 deg. to form the linearly polarized light orthogonal to the incident light.

Abstract: PURPOSE:To improve a current amplification factor in a high current region without lowering collector-base reverse breakdown voltage by forming a low resistance region in high impurity concentration into a region including a section just under an emitter region within a range narrower than a base region in a low impurity-concentration layer. CONSTITUTION:An N-type low resistance region 6 formed to an N-type layer 2 is formed in structure in which it exists just under an emitter region 11 but does not exist on the outer circumferential section of a P-type base region 8. Consequently, the impurity concentration of the N-type layer 2 as a collector region is not increased near the outermost circumference of the P-type base region 8 determining reverse breakdown voltage between a collector and a base while the impurity concentration of the collector region just under the emitter region 11 deciding the current characteristics of a current amplification factor can be elevated. Accordingly, the current amplification factor in a high current region can be improved without lowering reverse breakdown voltage between the collector and the base.

Title: Ion exchange resin
Inventor: INAMI ICHIRO
IPC: C08F8/06
Filed: 1989-05-19
Abstract: PURPOSE:To develop good fine particle removing capacity from the beginning of use without providing a pre-filter apparatus by preliminarily applying oxidizing treatment to the surface of an ion exchange resin within such a range that collapse strength exceeds a specific value. CONSTITUTION:The surface of an ion exchange resin is immersed in 3-30% aqueous hydrogen peroxide at room temp. for 3-120hr to be preliminarily subjected to oxidizing treatment within such a range that collapse strength exceeds 200g/particle. Since the surface and interior of a cation exchange resin are preliminarily oxidized to a proper degree in this ion exchange resin, the ion exchange resin becomes the same surface and interior state as one advanced in use and, therefore, fine particles can be rapidly dissolved and trapped from the beginning of use. As a result, even in a case using only an ion exchange resin tower, for example, the fine particles of the insoluble solid in the primary cooling water of a nuclear reactor can be stably removed with good removing capacity.

Title: Data input circuit
Inventor: GOTO HIROMOTO
IPC: G06F3/00
Filed: 1987-05-26
Abstract: PURPOSE:To eliminate the influence of distribution capacity by using a voltage control means which controls the charging voltage of the distribution capacity existing at the input side of a data processing circuit to a prescribed voltage level and a switching means which connects the input of the data processing circuit to the voltage control means in a middle stage where each input signal is selected. CONSTITUTION:Each input is selected with no bridge secured between inputs owing to the intervention of a no-contact state NC and at the same time the inputs 4X and 4Y of a multiplexer MPX4 are always selected in each middle stage where input signals S1-S7 are selected. In this case, the inputs of a data processor set at and after the buffer amplifiers BA5 and BA6 and a differential amplifier DA7 are connected to resistors R3 and R4 as well as voltage sources E1 and E2. Thus the charging voltage of the distribution capacity set at the input side is controlled by prescribed voltage levels of both sources E1 and E2 even though the distribution capacity set at the input side of the data processing circuit existing at the output X and Y of MPXs 1-4 through the inputs of both BA5 and 6 are charged by the immediately preceding input signal voltage. Thus an error of measurement is eliminated.
