Title: Film unit with lens
Inventor: KAWAMURA FUMINORI
IPC: G03C3/00
Filed: 1996-12-06
Abstract: PROBLEM TO BE SOLVED: To prevent a malfunction caused by the intrusion of sand from occurring. SOLUTION: Rails 45-48 are formed along the turning locus of a shutter blade 42 at the front surface 38a of a base member 38 and the rear surface 40a of a lens holder 40. The height L1 of the rails 45 and 46 and the height L2 of the rails 47 and 48 are set so that a gap D1 between the blade 42 and the front surface 38a and a gap D2 between the blade 42 and the rear surf ace 40a become wider than the width of a notch around a shutter button and a gap between the edge of an aperture for a knob and a winding-up knob. Since the grain size of the sand intruding a unit main body always becomes smaller than the gaps D1 and D2 , such an accident that the action of the blade 42 becomes unstable or the blade 42 cannot be moved is prevented from occurring because the sand is caught in the gaps D1 and D2 .  The cross sections of the rails 45-48 are shaped so that the width thereof becomes narrower toward the tip thereof. Besides, a rib abutting on the front surface of a lens presser and a rib covering the outside circumference of the lens presser are formed at the inside of the edge of an aperture for lens.

Title: Chromium sulfate for chromium based electroplating
Inventor: SUZUKI SHINICHI
IPC: C25D3/04
Filed: 1992-12-08
Abstract: PURPOSE:To highly efficiently attain adhesion of the chromium based electroplating by using a polyhydric alcohol derivative as the reducing agent itself or a part of it to be added to hexavalent chromic acid. CONSTITUTION:The hexavalent chromic acid is reduced to chromic sulfate contg. trivalent chromium by adding the reducing agent to it. The polyhydric alcohol derivative is used as the reducing agent itself or a part thereof. The trivalent chromium ion in a monomer state which is just formed by reducing the chromate ion is complexed with the polyhydric alcohol. The trivalent chromium ion, once complexed with the polyhydric alcohol derivative, is not easily converted to hydrated complexes. Therefore the monomer ratio of the trivalent chromium in this chromium sulfate is more than that in the conventional chromium sulfate. Thus the dehydration which is an obstructive step in the electroplating process is more easily performed by using this chromium sulfate than by the conventional chromium sulfate contg. a large amount of the macro- chromium complexes. As a result, the separation of the hydrated complexes in the electroplated layer can be avoided and the adhesion of the electroplating can be improved.

Abstract: PURPOSE:To shorten the time required for alignment work by detecting the highlight position of laser light reflecting on a corner cube and detecting the variation of hightlight position corresponding to the movement of a mobile and then correcting the movement with the correction factor of cosine error determined from the movement and the variation. CONSTITUTION:Light emitted from a laser 11 is split through a polarization beam splitter 13 in an interferometer 12 into a reference light and a length measuring light being reflected on a corner cube 14 secured to a mobile. Angle theta represents the angle between the linear track of the cube 14 and the optical axis of the length measuring light, L represents the moving distance of the cube 14 from point A to B, and DELTAX represents the lateral shift of the highlight position of light reflected on the cube 14. A counter section 21 receives a signal from an interference light detector 20 when the cube 14 moves by the distance L and determines a measured length L. The measured length L is fed, along with a highlight position X detected by a detector 15, to a cosine error factor calculating section 16 where the variation of highlight position AX and a cosine error correction factor alpha are determined. A cosine error correcting section 22 multiplies the measured length L by the correction factor alpha to determine a true moving distance.
