IPC: F16T1/02
Filed: 2000-03-15
Abstract: PROBLEM TO BE SOLVED: To provide a thermally-actuated steam trap capable of quickly discharging a large mount of low pressure condensate. SOLUTION: In a main body 3 having an inlet 1 and an outlet 2, a valve chamber 6 and a valve seat storing chamber 7 are communicated through an opening 10 and an orifice 11 having a large passing area. In the valve seat storing chamber 7, a valve hole 13 communicating the valve chamber 6 and an outflow passage 12 is provided, and a valve seat 15 provided with a throttle member 14 is arranged so as to move backward and forward. A first thermally- actuating element 17 is made of a coil-shaped shape-memory alloy, and shrinks at low temperature period to open the opening by a valve seat 5 and increase the passing area of the orifice 11 by the throttle member 14 of the valve seat 5. The first termally-actuating element 17 closes the opening 10 by the valve seat 15 and throttles the passing area of the orifice 11 by the throttle member 14 of the valve seat 15 under high temperature.  A second thermally-actuating element 19 opens/closes the valve hole 13 to discharge condensate under high temperature, at high temperature period when the valve seat 15 closes the opening 10 and throttles the passing area of the orifice 11.

Title: Multipoint range-finding camera
Inventor: TAKAHASHI MARI
IPC: G02B7/28
Filed: 2000-03-15
Abstract: PROBLEM TO BE SOLVED: To provide a multipoint range-finding camera capable of performing range-finding in two areas even when subject luminance is largely different by alternately performing optimum storing operation in both areas, respectively. SOLUTION: In the case a lens is not driven, a CPU 7 judges the previous range-finding area and selects an area A when the previous range-finding area is an area B or this range-finding is the first one. Then, the CPU 7 stores and transfers it so as to perform range-finding arithmetic operation. Based on the range-finding results of the areas A and B, the area on a close range side is selected. In the case the lens is driven, the CPU 7 selects the selected area on the close range side again, and performs storing, transferring and range- finding arithmetic operation in the same manner, then selects the same area as the previous one because the lens is driven. Since optimum storing operation is alternately performed in plural areas, range-finding is performed in the area even when the subject luminance is largely different in the respective areas.
