Abstract: PURPOSE:To eliminate measuring errors due to re-reflection by arranging the diffraction surface of a diffraction grating in a specified direction to incident reflected light to keep reflected light from a light detecting element from being incident into a photo detector again. CONSTITUTION:The diffraction surface of a diffraction grating 26 is arranged inclined in the non-spectroscopic direction by an angle alpha according to the position and size of a light detecting element 30 from the normal of the plane X containing incident reflected light to prevent reflected light from the light detecting element 30 from being incident on the detecting element 30 again. Light focused from the surface of an object makes a parallel light with a collimator lens 24 and is incident on the diffraction grating 26. The incident light is directly reflected in the non-spectroscopic direction and focused with a concave mirror 28 to be incident into the light detecting element 30. A part of light is reflected with the element 30, focused with a concave mirror and reflected with the diffraction grating 26 again. As the diffraction grating is inclined by alpha in the non- spectroscopic direction, light is focused at the position P separated by DELTAL from the element 30 through the concave mirror 28.

Abstract: PURPOSE:Not to leave warpages and to reduce the variability of pressure sensitivity based on variability of diameters of recesses or thicknesses of projecting warpages by performing the rough formation of recesses with an etching solution of high etching speed and performing the etching to a boundary with a low impurity concentration layer with an etching solution of low etching speed. CONSTITUTION:On one end of a high concentration single crystal Si substrate 2 including arsenic, an n type low impurity concentration layer 3 is epitaxially grown to form a concentration boundary 6 and a p type warpage gauge region 4 is formed in said low impurity concentration layer 3. Next, from another side of the Si substrate 2 corresponding to the warpage gauge region 4, 75-95% of the thickness of the high impurity Si substrate 2 is removed to form a recess.

Title: Manufacture of plate for alkaline cell
Inventor: OGAWA TADAHIKO
IPC: H01M4/29
Filed: 1985-11-06
Abstract: PURPOSE:To fill nickel hydroxide uniformly into a sintered member by performing electrolysis intermittently while maintaining a pressure reduced condition above the liquid level of a nickel salt electrolyte thereby removing foam to be produced in the gaps of the sintered member employed in an anode. CONSTITUTION:When electrolysis in a nickel salt electrolyte is performed while employing a sintered member being employed as an anode, it is performed intermittently in the condition where the pressure above the liquid level of the electrolyte is maintained to be reduced. Since the foam to be produced continuously in the gaps of the sintered member is removed during suspension of electrolysis, in case of intermittent electrolysis, nickel hydroxide can be deposited and filled uniformly into the micro voids. Consequently, in a cell employing such a plate, the energy density can be improved through the high rate of discharge characteristic, the service life and the capacity.
