Title: Conduction inspecting jig for printed wiring board
Inventor: MIYAGAWA YOSHIHARU
IPC: H05K3/00
Filed: 1992-02-25
Abstract: PURPOSE:To obtain a jig, which has excellent reliability, can be manufactured at a low cost and can cope with a high-density printed wiring board, by using an intermediate plate as a laminated plate having the same thermal expansion coefficient as the wiring board, and coupling a guide hole and a probe pin by shrink fitting. CONSTITUTION:A probe pin 3 in a unitary form is held with an intermediate plate 4 on the opposite side of the electrode of a converting plate 5, which is mounted on an electrode 6 of a conductance inspecting machine. The top part of the pin 3 is connected to a printed wiring board 2 under inspection, and the opposite side is connected to the converting plate 5. A press head 1 is lowered so as to enhance the reliability of the wiring board 2, the pin 3, the converting plate 5 and the electrode 6. The stroke can be finely adjusted so that head 1 is pushed in the range of the stroke of the pin 3. The press head 1 is stopped within the range of the stroke of the pin 3. A conducting circuit is formed among the pin 3, the converting plate 5 and the electrode 6. The inspection of the printed wiring board 2 having the land, which is arranged on the grid or not arranged on the grid, can be performed with the conduction inspecting machine having the electrodes on the grid.

Abstract: PROBLEM TO BE SOLVED: To uniformly condense the light from right and left stripe pixels forming a stereoscopic viewing region and to assure the wide visual stereoscopic viewing region in the vertical direction by adequately setting the pitch in the horizontal direction of openings and the width in the vertical direction thereof. SOLUTION: The openings 8 of mask patterns 9 are formed to checkered patterns and are formed to correspond to the respective stripe pixels to be displayed on a liquid crystal display 6 in a vertical direction and to correspond to respective cylindrical lenses for every kind of the stripe pixels. The pitch in the vertical direction of the openings 8 is set slightly larger than the pitch of the stripe pixels displayed on the liquid crystal display 6. The opening width in the vertical direction of the openings 8 is set smaller than the width of the stripe pixels. Then, the good stereoscopic images are observed even if the display device of a low display speed is used and the viewing of the right and left parallactic picture uniform over the entire part of the screen in the observation position of a prescribed height is possible.  The observation region in the vertical direction is thus widened.
