Title: Optical wavelength conversion element
Inventor: YAMADA MASAHIRO
IPC: G02F1/37
Filed: 1988-10-11
Abstract: PURPOSE:To obtain a circular second harmonic wave radiation beam by constituting a light guide formed on a nonlinear optical material substrate of 1st waveguides to confine a basic wave and a 2nd waveguide to confine the second harmonic wave. CONSTITUTION:The light guide 2 formed on the nonlinear optical material substrate 1 is formed of the 1st waveguides 2a, 2c which confine the basic wave and convert the same to the second harmonic wave and the 2nd waveguide 2b which confines the second harmonic wave, propagates the same in the end face direction and radiates the wave form the end face in the generation of the second harmonic wave by Cherenkov radiation. The basic wave confined in the 1st waveguides 2a, 2c of the light guide is, therefore, efficiently converted by its own energy density and the nonlinear optical effect of the 1st waveguides 2a, 2c and the substrate 1 to the second harmonic wave of the wavelength half the wavelength of the basic wave. The converted second harmonic wave is confined in the 2nd waveguide 2b and propagates in the 2nd waveguide 2b while repeating a guide mode or reflection. The circular or elliptic beam is radiated from the end face in this way.

Title: Method for soldering coated wire
Inventor: ABE TOKUYOSHI
IPC: B23K3/04
Filed: 1990-09-26
Abstract: PURPOSE:To efficiently join products of mass-production by heating a lead wire with the coating film melt removed, feeding a solder to the lead wire and holding a terminal member between electrodes until the solder solidifies. CONSTITUTION:The lead wire 3 with coated end part 3a is wound to the terminal member 4. The wound terminal member 4 is held between the electrodes 7, 8 generating heat with electric conduction. By sending electric current into the electrodes 7, 8, the coating film on the lead wire 3 wound to the terminal member 4, is melted and removed. Together with this, the lead wire 3 with the coating film removed, is heated and the solder 12 is fed on the heated lead wire 3. After stopping electric conduction to the electrodes 7, 8, the terminal member 4 is held between the electrodes 7, 8 until the solder solidifies. By this method, the joining work can be completed in a short time without requiring man-hour so much.

Abstract: PURPOSE:To miniaturize and simplify a device by providing a wavelength converting element with a smaller diameter than an infrared beam for converting the infrared beam into an ultraviolet beam in a light path between an infrared laser source and an objective lens. CONSTITUTION:A beam of light emitted from an infrared and visible LD array 5 is reflected by a polarized beam splitter (PBS) 7 via a collimator lens 6 and condensed on an optical disk 2 with a photochromic film via a lambda/4 plate 8 and the objective lens.

By this differential output, a focus error signal is obtained. On the other hand, a beam of light from an infrared LD 21 is converted by the wavelength converting element 24 into the ultraviolet beam via a lens 22 and a shaping prism 23. The ultraviolet beam and peripheral infrared beam are reflected by the DM 12 via the lambda/4 plate 11, retrograding to the incident upon the disk 2 via the PBS 7, the lambda/4 plate 8 and the lens 9, so that a bit of information is recorded.

Title: Illumination optical fiber
Inventor: YUNOKI ISATO
IPC: G02B6/00
Filed: 1995-10-03
Abstract: PROBLEM TO BE SOLVED: To uniformly light the intermediate area of an optical fiber by providing a lighting part provided with a tapered part where the diameter of an outer peripheral surface is successively reduced and an inverse tapered part where the diameter of the outer peripheral surface is successively enlarged from a minimum diameter part continuously from the tapered part. SOLUTION: The lighting part 14 is constituted of the tapered part 12 where the outer peripheral surface is successively reduced from one end side to the other end side of the optical fiber 11 and the inverse tapered part 13 where the diameter of the outer peripheral surface is successively enlarged from the minimum diameter part to the other end side of the optical fiber 11 continuously from the tapered part 12. Then, when light advancing inside the optical fiber 11 is internally reflected at the tapered part 12, the angle of the light to the optical axis of the optical fiber 11 becomes large. As a result, when it does not suit conditions for making the light advance inside the optical fiber 11 while performing total reflection, the light leaks from the optical fiber 11.  At the time, since the light leaks from the entire peripheral surface of the lighting part 14, lighting is uniformly performed in the intermediate area of the optical fiber 11.
