Abstract: This invention provides an azomethine compound that can realize a good coupling reaction and, at the same time, can significantly reduce the production cost of the azomethine compound, the azomethine compound comprising a pyridine ring bonded through a nitrogen atom to a 1H-pyrazolo[1,5-b][1,2,4]triazole ring. The azomethine compound is represented by formula (M-I): wherein R1 represents a phenyl group or a naphthyl group optionally substituted by an alkyl group or a halogen; and R2 and R3 each independently represent a C2-4 (number of carbon atoms) alkyl group.

Abstract: To prevent incorrect operation of an operating member provided in an electric component box without giving complicated processing on a front panel. An opening formed in the front portion of a housing (11) to correspond to a machine room (14) is closed with a front panel (20). A suction louver (25) and a delivery louver (26) are formed in the front panel (20). An inserting/withdrawing opening (28) used for inserting/withdrawing a filter (34) is opened above the position for forming the suction louver (25) in the front panel (20). A base portion (38) being fitted in the inserting/withdrawing opening (28) to close the opening (28) is formed above the filter (34). A power switch (43) and a service switch (44) are provided on the front of the electric component box (42) arranged in the machine room (14). The portion for arranging the power switch (43) and the service switch (44) in the electric component box (42) opposes the rear of the inserting/withdrawing opening (28).

Abstract: A down flow type ice making machine in which an ice storage detector is protected against damage and occurrence of failure can be suppressed. An ice storage bin (12a) for storing ice cubes (M) is defined in an ice storage compartment (12). Upper rear wall (16) of the ice storage compartment (12) is formed of a wall portion (16a) extending vertically, and a wall portion (16b) extending horizontally rearward from the lower end of the vertical wall portion (16a). At an upper portion in the ice storage bin (12a), a down flow ice making unit (18) is arranged while spaced apart by a predetermined interval forward from the vertical wall portion (16a) and ice cubes (M) produced by the ice making unit (18) are stored in the ice storage bin (12a). Below the ice making unit (18), an ice making water tank (32) equipped with a section (32a) for collecting ice making water not used for making ice cubes in the ice making unit (18) is disposed.
