Abstract: PURPOSE: A regular refrigerating mechanism of a refrigerator is provided to keep temperature of a refrigeration compartment regular without staying cold air on a spot by using a cold air circulating fan for flowing cold air to all of parts in the refrigeration compartment. CONSTITUTION: A refrigerating cycle is started when temperature of each compartment in a refrigerator exceeds set temperature. Heat between refrigerant and cold air is exchanged in an evaporator(25), and the relatively low-temperature cold air is supplied to a freezer compartment(30) and a refrigeration compartment(40) by a blower fan. The cold air flows to the freezer compartment through a shroud(28) to circulate the inside. Then the cold air is returned to the evaporator through a return path(35). The other remaining cold air is supplied to the refrigeration compartment. The refrigerator duct discharges the cold air to each shelf of the refrigeration compartment. A cold air circulating fan(50) flows the cold air discharged to the center of the refrigeration compartment, toward a door(47). The cold air flows to the rear of the refrigeration compartment along both sidewalls of the refrigeration compartment. The cold air is heat-exchanged with food in the refrigeration compartment. Therefore, the cold air rises up to the refrigeration compartment to return to the evaporator.

Abstract: PURPOSE: A process for producing an electrophotographic photosensitive member is provided. CONSTITUTION: An electrophotographic photosensitive member obtained by the process of the present invention has a layer formed by coating a dispersion (fluid dispersion) followed by drying, which is obtained by ejecting a pressurized fluid from an orifice into a hollow member having a diameter (inner diameter) larger than the diameter of the orifice, to disperse a material to be dispersed; the fluid being ejected in substantially an unatomized state. Dispersion is carried out first at the time the fluid passes through the orifice and is ejected into the hollow member. The fluid having been ejected stands substantially not atomized, and is jetted into the hollow member in the state of a high-velocity jet stream. Hence, the dispersion is effected by the aid of a shear force acting between the fluid flowing into it and the fluid stagnating in the hollow member after it has flowed in. Thus, the dispersion can be effected well efficiently and in a narrow particle size distribution. The electrophotographic photosensitive member produced using the resultant fluid dispersion promises images free of faulty images such as spots and image fog.
