Abstract: PROBLEM TO BE SOLVED: To prevent the deposition of dust on a mirror finished surface and more particularly a third mirror finished surface by respectively specifying the angles formed by a second mirror and a third mirror with a horizontal plane and the end positions of the respective mirrors. SOLUTION: The second mirror 11 and the third mirror 13 are inclined at the angle of 45 deg. with the horizontal plane and are disposed in a moving frame 13 in such a manner that the mirror finished surfaces face each other. The extension line extended from the end 12a existing on the rear surface side of the moving frame of the third mirror 12 viewed from the flank is intersected with the second mirror 11. Further, the distance (x) between the end 11a existing on the rear surface side of the moving frame of the second mirror 11 and the intersected point P of the extension line extended from the end 12a existing on the rear surface side of the moving frame of the third mirror 12 and the second mirror 11 is set at least at cam. The dust is drifted and carried by the air flow A in a copying machine to form turbulent flow.  Since the end 11a of the second mirror 11 exists on the rear surface side of the end 12a of the third mirror 12, the turbulent flow arises on the rear surface of the third mirror 12 and the influence of the turbulent flow on the adhesion of the dust is averted.

Title: Air conditioner
Inventor: NAKAZAWA AKIHISA
IPC: F25B13/00
Filed: 1988-08-31
Abstract: PURPOSE:To definitely inhibit an abnormal pressure rise on a higher pressure side by installing a means which is dedicated to close a first on/off valve only when it is necessary to close both the first on/off valve and a second on/off valve. CONSTITUTION:During heating load based on a rise in room temperature, an abnormal pressure rise on a higher pressure side must be checked by closing a save valve 9. During that time, a detection temperature Teo of a refrigerant temperature sensor 14 may exceed 65 deg.C some times. In this case, a control means 20 allows the closing operation of the save valve 9 to have priority and maintains an open state as for a bypass valve 11. As a result, this construction eliminates an excess pressure rise on the higher pressure side and is capable of inhibiting an abnormal pressure rise on the high pressure side without fail. It is, therefore, possible to avoid unnecessary operation shut down due to a high pressure switch 12 and performing stable operation.
