Title: Focus detecting device
Inventor: OSAWA KEIJI
IPC: G02B7/34
Filed: 1996-02-14
Abstract: PROBLEM TO BE SOLVED: To reduce the influence of a chromatic aberration on focus detection precision as much as possible on the ultraviolet side. SOLUTION: An infrared cutting filter 2 arranged in a focus detection optical system cuts light on a longer wavelength side than about 710nm as infrared-side light and also cuts light on a shorter wavelength side than about 450nm a little longer than the lower limit of specific luminous efficiency on the short- wavelength ultraviolet side. Consequently, the influence of the chromatic aberration of a photographic lens becomes small on both the long-wavelength side and short-wavelength side and the influence of the chromatic aberration is reduced.

Title: Peelable paint
Inventor: AOYANAGI SEIICHIROU
IPC: F24F7/013
Filed: 1984-02-15
Abstract: PURPOSE:To provide the titled paint for electrical appliances, etc., forming a peelable coating film on the surface of the constituent part of machines, such as the decorative frame, blades, etc. of ventilation fan, etc., capable of removing the attached stain together with said peelable coating film to save the labor of cleaning, by using a basic substance and a coloring reagent as essential components. CONSTITUTION:The objective paint can be produced by compounding (A) an acrylic resin with (B) a basic substance (e.g. ammonia) and (C) a coloring reagent (e.g. phenolphthalein). The paint has red color in the prepared state because of its alkaline nature of 8-10pH, however, the pH is lowered by the evaporation of water and ammonia after coating, and the coating film becomes colorless and transparent. EFFECT:The coating operation can be carried out conveniently because the uncoated part can be discriminated from the coated part in the course of coating, and the good appearance of the part is maintained because the color of the coated part becomes the original color of the part by drying.
