Title: Automatic focusing camera
Inventor: KUSAKA YOSUKE
IPC: G02B7/28
Filed: 1993-03-12
Abstract: PURPOSE:To provide an automatic focusing camera capable of performing accurate predicted driving even at low luminance. CONSTITUTION:A 1st sensor 9 and a 2nd sensor 10 whose detecting sensitivity of an object image is higher than the 1st sensor 9 are juxtaposed by a photodetector 8 receiving the object image guided from a focus detection optical system 7.

Title: Laminated filter
Inventor: KIMURA NORITOSHI
IPC: B01D39/14
Filed: 1994-02-25
Abstract: PURPOSE:To efficiently collect fine particles in a liquid and to treat a large amt. of a liquid in low pressure loss by forming the fiber layer of a laminated filter from a high density fiber layer and a low density fiber layer and forming a through-hole to the hilter from the inflow surface of a liquid to be treated of the filter to the outflow surface thereof. CONSTITUTION:As the filter layer of a laminated filter, a high density fiber layer 11 and a low density fiber layer 21 are laminated and a through-hole 31 is formed to the filter from the inflow surface of a liquid to be treated of the filter to the outflow surface thereof. Therefore, at an initial stage of use, the liquid to be treated is mainly distributed to the low density fiber layer 21 and the through-hole 31 to flow and, when particles in the liquid to be treated are collected by the fiber layer to clog the fiber layer, the liquid to be treated mainly flows through the through-hole 31. As a result, liquid passing resistance is lowered and a large amt. of the liquid can be treated. Since the liquid to be treated flows through the low density fiber layer 21 while it collides with the fibers of the low density fiber layer 21, the liquid does not flow as laminar flow and becomes turbulent flow to frequently come into contact with the high density fiber layer 11 and, therefore, fine particles causing the contamination or turbidity in the liquid are efficiently collected.
