Title: Laser diode module
Inventor: MORI MASAKAZU
IPC: H01S5/00
Filed: 1986-10-14
Abstract: PURPOSE:To prevent the signal waveform of an output of a laser diode module from being contaminated due to the dispersing characteristic of an optical fiber by introducing the multimode output beam of a laser diode incident to a diffraction grating formed at a predetermined angle to the irradiating direction and introducing the reflected optical beam to the optical fiber set at the predetermined angle. CONSTITUTION:The multimode optical beam irradiated from an LD chip 1 is incident through a lens 4 to a diffraction grating 5 set to an irradiating direction near a brazing angle. The reflected light is incident to a lens 6 at different optical path differences  L1- L3 according to the wavelengths, the transmitted light is incident through a lens 7 to an optical fiber 3 to propagate at different propagating speed according to the wavelength. The position of the lens 6 is set so that the optical path differences  L1- L3 become suitable values to cancel the delay of the waveform due to the difference of the wavelengths in the fiber 3.

Abstract: PURPOSE:To change an angle in a maximum radiating direction without physically moving an antenna itself by switching two feeding lines and radiating the radiation pattern of a pencil beam whose angles of two types beam peaks are slightly different. CONSTITUTION:Now, when a bias voltage is added to one diode 6 and a circuit is made short, since an impedance to observe the diode 6 side from a branching point (b) and a branching point (c) goes to be extremely large, a feeding is executed from a branching point (a) through a branching line 4a which goes from the branching point (c) through the hot end of a diode 5. The branching point (a) is made off-set only by a (d) in an (x) axial direction from the center of a microstrip line 4 and a synthesized electric field from respective elements goes to be a maximum in -theta direction. When the bias voltage is added to the diode 5, the maximum radiating direction lies in the +theta direction.

Abstract: PURPOSE:To produce the title polymer thin film for an electrochromic display having a high reaction rate by electrolytically oxidation-polymerizing an oxidation-polymerizable material on the surface of a positive electrode at a specified temp. in an electrolytic soln. contg. an electrolyte and the oxidation-polymerizable material. CONSTITUTION:The electrolyte and oxidation-polymerizable material are dissolved in a solvent to form an electrolytic soln., and a deposition electrode and a counter electrode are dipped in the soln. in opposition to each other. LiBF4, etc., are appropriately used as the electrolyte, polythienylene, etc., as the oxidation-polymerizable material, and dehydrated propylene carbonate, etc., as the solvent. The ITO film, etc., formed on a glass substrate is used as the deposition electrode, and Pt, etc., as the counter electrode. A voltage of about 1-20V is impressed between both electrodes with the deposition electrode as a positive electrode and the counter electrode as a negative electrode. As a result, the oxidation-polymerizable material is electrolytically oxidation-polymerized to form a thin film on the surface of the deposition electrode. In this case, the reaction temp. in the electrolytic oxidation polymerization is controlled to <=0 deg.C and above the freezing point of the solvent. By this method, the polymer thin film for an electrochromic display having high conductivity, reaction rate, and reaction quantity is obtained.

Abstract: PURPOSE:To suppress smear phenomenon and to decrease noise by providing a means amplifying an electric charge by an incident light into a voltage or a current and a detection means obtaining a difference of outputs of an ampli fier means when a signal charge is given and/or not to an input section of the amplifier means. CONSTITUTION:When a light is made incident in photodiodes 11, 21, 31, and 41, a signal charge is stored in each photodiode corresponding to the incident luminous quantity.

Thus, the deterio ration in the S/N due to leakage of noise charge in the signal path from the photodiodes 11, 21, 31 and 41 to the output amplifier is suppressed remarkably. The smear phenomenon caused by the leaked noise charge caused by the inci dent light is also suppressed considerably.

IPC: G01N19/04
Filed: 1989-09-22
Abstract: PURPOSE:To non-destructively measure an adherent force by expressing a correlation between the adherent force obtained by a destructive test and the temperature characteristic value of a film surface in a calibration curve. CONSTITUTION:Blasting particles 14 are blown against the upper surface of a base material 13a to be roughened and a coating material 16 is thermally sprayed and accumulated by a thermal spray gun 15 to form a film D. A base material 13b to which a blasting processing is applied is adhered to a trial test piece 12 processed as above via an adhesive E, a tensile load F is gradually applied to the test piece 12 and an adherent force is calculated from the load when the film D peels off the base material 13a. Destructive tests are thus executed on a plurality of the trial test pieces with different adherent forces. On the other hand, after heated under a given heating condition, the temperature characteristic values of the film surfaces of the trial test pieces are obtained by an infrared ray image apparatus and a calibration curve indicative of a relationship between the temperature characteristic values and the adherent forces is formed. When, after heated under the same condition, the temperature characteristic value of the film surface of an object to be tested is measured in the same fashion and applied to the calibration curve, the corresponding adherent force can be calculated.
