Abstract: PURPOSE:To certainly detect erroneous operation of a winning ball detector by influence of external electromagnetic wave or magnet by providing a detector of the same principle as the winning ball detector in a position not related to the passage of the winning ball. CONSTITUTION:To a guide gutter 25, through the outlet 26 of which winning balls are passed one by one, a large prize hole winning detector 30a for detecting the passed winning balls faces. A V winning detector 30 faces to a V winning hole 28, and an opening and closing door 23 is opened by the operation of this. Further, in a fluctuating prize winning device 20, an unfairness detector 30b is disposed on one lower side of an enclosing frame 24, which is a position other than the passage of winning balls. The unfairness detector 30b has the same structure as the V winning detector 30 and the large prize hole win ning detector 30a. When the winning ball detectors 30, 30a are influenced by external electromagnetic waves and erroneously operated, the unfairness detector 30b is also operated. Reversely, if the influence given by the external electromagnetic wave is such that the winning ball detectors 30, 30a are not erroneously operated, the unfairness detector 30b is not operated either. Thus, the influence by the external electromagnetic wave can be certainly detected.

Title: Heat exchanger
Inventor: MORI OSAMU
IPC: F25B39/02
Filed: 1998-03-18
Abstract: PROBLEM TO BE SOLVED: To improve a cooling rate without causing a drop in ventilation due to frosting in a heat exchanger of a refrigerator and the like. SOLUTION: By forming a fin 22 penetrating a refrigerant pipe 23 of a heat exchanger 13 into an inverted trapezoidal shape wherein the width thereof is reduced on the side of an air inlet 16 of a cooling chamber and increased toward the side of an air outlet 15, a more space 25 is obtained in a space from the cooling chamber 12 on the suction side where much frost is formed. The heat exchanger is not blocked even in the case the fin 22 and the like is covered with frost in the space 25, air flows smoothly to circulate a sufficient amount of cool air, so that the cooling performance is improved.  The space formed in the manner as above eliminates a front projection of a wall part where a volume in a refrigerator is oppressed as before and a rear projection of the wall part where the thickness of a heat insulating wall is reduced causing a leakage of heat, and thus an energy saving and space saving refrigerator 1 of simple construction and design is realized for high cooling performance.
