Title: Optical information reproducing device
Inventor: OKI YASUSHI
IPC: G11B7/135
Filed: 1999-12-20
Abstract: PROBLEM TO BE SOLVED: To prevent resolution from being lowered through the mixing of a high-order diffracted light beams of a different phase, in an optical information reproducing device that performs super-high resolution using a diffraction grating. SOLUTION: A laser beam emitted from a laser diode 101 is collimated by a collimator lens 102, divided into three beams by the diffraction grating 103, and converged on the center of each transmitting opening of plural diffraction gratings 106 having different cycles by an objective lens 105. The diffraction grating 106 is a sine amplitude grating, only zeroth-order and ±1st order diffracted light are emitted on the recording face of an optical disk 107. Thus, a modulated optical spot has no high-order diffracted light components with a reversed phase; hence, a reproducing signal detected by a tripartite photodetector 109 and synthesized by an adder 112 is free from distortion, enabling super- high resolution to be obtained over a wide band.

Title: Apparatus for inspecting solder joined part
Inventor: ISHIGAME TORU
IPC: G01B11/24
Filed: 1999-12-22
Abstract: PROBLEM TO BE SOLVED: To provide an apparatus capable of suppressing brightness fluctuations in a peripheral direction and capable of increasing the quantity of irradiation light to a steep slope. SOLUTION: The light emitted from the optical fiber 412 in a ring light guide 411 is incident on a smooth plate 43 and irregularly reflected within the smooth plate 43 to advance in a length direction. As a result, brightness distribution in a peripheral direction is smoothed and brightness fluctuations in the peripheral direction are reduced. A part of the light reflected from a deflection surface (primary reflection surface) 431 is emitted to the outside and the remainder thereof is allowed to irradiate a primary diffusion surface 421. The light emitted along a light path C is reflected by a printed circuit board (secondary reflection surface) 1 and is reflected in a vertically upward direction by a slope with an angle γ of inclination.  As a result, the quantity of irradiation light to the steep slope (angle γ of inclination) of a solder joined part 11 is increased and the step slope becomes bright by secondary reflection action. The image taken by a camera 5 becomes bright as a whole and becomes easy to see because of an increase in the contrast.
