Title: Photometer for camera with automatic focus function
Inventor: YAMADA AKIRA
IPC: G01J1/44
Filed: 1986-03-03
Abstract: PURPOSE:To output photometry information which is narrowed down to a main subject whose distance is measured by providing a control means which determines final photometry information on the basis of light measured values obtained in respective areas of a photometer after confirming the focusing of a photographic lens on the subject. CONSTITUTION:When it is judged that the photographic lens reaches an in-focus position, a motor 31 is stopped and an AF end signal is outputted to an arithmetic control circuit 24 at the same time. The arithmetic control circuit 24 stores the signal as information on subject brightness measured by a silicon photodiode SPD 1. Then the diameters of areas where light is measured by SPDs 1-3 are denoted as AC from the inside and, for example, when A<1<B, a value obtained by weighting the center part is regarded as final brightness (photometry information) in photography like this. Thus, pieces of brightness information are obtained from the respective divided light measurement areas after the photographic lens is put in focus and weighted to determine the final brightness information, so light measurement which is narrowed down to the main subject is performed with good brightness.

Abstract: PURPOSE: A pharmaceutical preparation for solid drugs having improved uniformity of content and stability, comprising powdery or granular substance obtained by coating a very small amount of a drug with wax.  
     CONSTITUTION: The titled pharmaceutical preparation comprising a powdery or granular substance with a very small amount of a drug (e.g., formoterole fumarate, β-methyldegoxin) coated with wax (e.g., hardened castor oil, bees wax).
