IPC: A61B3/14
Filed: 1995-07-17
Abstract: PROBLEM TO BE SOLVED: To make it possible to align and adjust the focus of a fundus camera on infrared fluorescent photographing without interference by obstructive reflected light of illuminating light by providing the camera with a variable means of changing the size of a ring slit or the size of shading point by the combination of an exciter filter and a barrier filter for photographing or for observing. SOLUTION: In the case of photographing mode for still picture, switching mirrors 17 and 22 are inserted respectively on light paths 02 and 03, the light beam from the light source 2 for observation is once imaged on the photographing light source 4 with a condenser lens 3, is transmitted there, is imaged on a ring slit 7 and then obstructive reflected light of illuminating light caused by a crystalline lens of an examined eye E is removed by a large shading point 8a and also obstructive reflected light of illuminating light caused by the cornea of the examined eye E is removed by a large shading point 12a.  While in the case that moving picture photographing mode is selected, the switching mirror 17 is inserted on the light path 02 and the switching mirror 22 is removed from the light path 03 therefore the light beam from the light source 2 for observation is once imaged on the light source 4 for photographing by the condenser lens 3 and transmitted there.

Filed: 1997-07-30
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of a thermal shock and uniformly pressurize a front panel side surface by swelling the width directional folded part of an explosion-proof reinforcing band only toward the outside, and separating the folded part from the front panel side surface part. SOLUTION: An explosion-proof reinforcing band 6 is made into a double structure by folding it along the longitudinal direction to enhance the reinforcing effect. It has a substantially circular folded part 7 in the width directional section, and the folded part 7 has a swollen part 8 swollen only outward to a front panel side surface part 4 and is flattened on the side opposed to the front panel side surface part 4. Since the explosion-proof reinforcing band 6 is swollen only to the outside, and an adhesive tape 9 is interposed, the explosion-proof reinforcing band 6 is surely separated from the front panel side surface 4, which causes no thermal shock.  The curvature radius of the width directional section of the explosion-proof reinforcing band 6 of the folded part 7 is preferably set to 1.1.-1.5 times the plate thickness (t=2.2-3.0 plate thickness) in order to prevent the cracking in the folded part.

Abstract: PURPOSE:To improve performance in feeling and power saving, by providing a restricting device in a suction port for controlling a refrigerant pressure sucked by a compressor, and controlling a refrigerant pressure in an evaporator to maintain the pressure constant or appropriate in response to a change in cooling load. CONSTITUTION:Even in the case that a refrigerant in a compression chamber cannot be sufficiently bypassed to a suction chamber 8 only by a bypass port 41 during high-speed rotation of a compressor, a discharge may be sufficiently reduced and a power consumption may be therefore reduced, by restricting a quantity of the refrigerant flowing into the suction chamber 8 by means of a restricting device having a plunger 101 provided in a suction port 100. Further, pressure in an evaporator may be controlled to a target pressure by controlling the pressure in a suction pipe 105 by means of the restricting device in the suction port 100. AT the same time, pressure in the suction chamber may be lowered sufficiently more than the pressure in the evaporator 505. Accordingly, the quantity of the refrigerant to be sucked into the compression chamber may be reduced to thereby sufficiently decrease the discharge. As a result, the performance in cooling feeling and power saving may be improved.
