Title: Mounting tool for metal foil molding and metal foil molding
Inventor: MORITA HIROSHI
IPC: F24F7/06
Filed: 1996-12-27
Abstract: PROBLEM TO BE SOLVED: To improve safety and reliability as a stopper in a metal foil molding wherein edge winding parts of divided parts are engaged with each other to permit the divided parts to be slidably engaged with each other. SOLUTION: The amount of winding of an edge winding part at an end 19 of a divided part 5 is larger than that of an edge winding part of a body part 23. In contrast, the length of an edge winding part at an end of the divided part 3 is longer than that of a body part 27, and edge winding of the edge winding part is opened. In this state, the edge winding 13c of the divided part 5 is inserted into the edge winding 7c of the divided part 3, and then the end part 25 of the divided part 3 is bent along the edge winding 13c of the divided part 5 to complete the edge winding 7c as an edge winding. Hereby, the divided part 3 and the divided part 5 are engaged with each other, and hence the edge winding of the end part 19 of the divided part 5 and the edge winding of the end part 25 of the divided part 3 serve to prevent disengagement therebetween as a stopper mutually.

Title: Camera with line-of-sight sensing means
Inventor: WATANABE TOSHIMI
IPC: G03B13/36
Filed: 1991-12-10
Abstract: PURPOSE:To eliminate risk of the photographer's line of sight being moved by the indication given in the finder and prevent missensing of the position of the line of sight by introducing such a system that the indication made by an indicating means is made in the unprominent mode during sensing of the line of sight. CONSTITUTION:A control means 1 monitors the condition of lighting indication through an indication control means 5, and if normal indication, the means 5 puts off the indication so that it does not attract the intention of the photographer. If sensing of the line of sight is performed soon after the indication is put off, it is likely that the position of the line of sight is set off due to stimulance of putting-off, so that the control means 1 gives order to a line-of- sight sensing means 2 to be waiting for a certain period of time (for example, 50ms). Then the line of sight is sensed by the means 2, and the line-of-sight sensing position is determined. A setting means 3 sets one of a plurality of distance measuring areas on the basis of the determined line-of-sight sensing position. Then the indicating condition of an indicating means 4 is again monitored, and if put off, the indication is re-lighted up.
