Title: Shutter device
Inventor: NOTO GORO
IPC: G03B9/24
Filed: 1994-10-12
Abstract: PURPOSE: To obtain an appropriate photographic aperture shape by a simple constitution by shielding an aperture in the longitudinal direction from light by a light shielding means with a shutter blade for forming a nearly diamond- shaped aperture in the process of opening, and forming the aperture to a nearly circular shape. CONSTITUTION: When a control member 6 is driven in a direction shown by an arrow in an opened state where aperture diameter deciding blades 2 and 3 are retreated outside the diaphragm open diameter D, a driving lever 5 is rotated by a driving pin 6a counterclockwise, then, the aperture diameter deciding blade 2 enters inside the diaphragm open diameter D by taking a shaft 1a as a guide. Simultaneously, a connecting bar 4 is rotated by a connecting pin 2a clockwise, the aperture diameter deciding blade 3 enters inside the diameter D through the connecting pin 3a by taking a shaft 1b as a guide.  Thus, the aperture shape of the shutter blade served also as a diaphragm is partly shielded from the light by the aperture diameter deciding blades 2 and 3, and the diaphragm aperture is formed from the nearly diamond-shape to the nearly circular shape, so that an optical performance such as peripheral peripheral light quantity, etc., can be improved.

IPC: G06F12/10
Filed: 1984-11-22
Abstract: PURPOSE:To reduce hardware quantity by providing an address conversion mechanism into a memory device to convert a logical address into a real address. CONSTITUTION:A CPU1, a channel CHU2 and a main memory MMU4 containing an address conversion mechanism ATN3 are connected to a path 5 in a computer system.

Those produced logical addresses are supplied as they are to the ATN3 via the path 5 to be converted into real addresses. These real addresses are supplied to the MMU4 and used for access operations. Thus just a single address conversion mechanism suffices for reduction of the hardware quantity.
