Title: Automatic focusing system
Inventor: SHIRAISHI AKIHIKO
IPC: G03B13/36
Filed: 1988-04-11
Abstract: PURPOSE:To execute normal focusing even when a photographic lens for a different kind of camera having an AF function has been installed by inserting and attaching an auxiliary optical system between an image face of a camera body and the photographic lens and converting the depth of the photographic lens and an allowable circle-of-confusion diameter to values corresponding thereto of the camera body side. CONSTITUTION:An auxiliary optical system 3 is a thin lens and arranges optical axes and inserts and attaches, and separates them between a lens part 1 and an image face 2. Each section of A shows the focal depth (focused depth range) in each stop position, and each section of B shows the focused depth range in each stop position requested by the camera body. Accordingly, it will suffice that a composite system of the lens part 1 and the auxiliary optical system 3 satisfies the focus depth of B in each stop position. When magnification of the auxiliary optical system 3 is denoted as beta, an allowable circle-of-confusion diameter becomes beta times of said diameter before the auxiliary optical system 3 is installed. In such a way, even if an interchangeable lens for a different kind of camera is used, an AF function can be operated normally.

Abstract: PURPOSE:To obtain carbon fiber chops excellent in bundling properties and form in a low sizing rate so that the sizing agent adhesion rate of carbon fiber chops is 0.5-5wt.%, a bundling property is 1.05 or less and a flatness rate is 12 or less. CONSTITUTION:A sizing agent adhesion rate is set to 0.5-5% and, in the case of below 0.5%, chops are opened to generate hairs and the emission irregularity from an extruder is generated and the cutting of a strand is generated. In the case of +5%, composite characteristics lower. A bundling property is set to 1.05 or less and, in the case of more than 1.05, chops are opened. The bundling property is obtained by dividing the A bulk density of chops after stirring in a mixer by that of the chops before stirring. A flatness rate is set to 12 or less and, within this range, the dry blending property of chops is enhanced. By this constitution, carbon fiber chops excellent in bundling property and form are obtained in a low sizing rate.
