Abstract: To provide a drainage pump capable of reducing the amount of drain water remaining in a drain pan. A drainage pump includes a housing, an impeller housed in the housing, and a motor with a drive shaft connected to the impeller. The housing includes a suction pipe in a cylindrical shape extending in an up-and-down direction. A suction port facing downward and a concave surface in an annular shape around the suction port are disposed at a lower end of the suction pipe.

Abstract: A drain pump that maintains pump performance and reduces noise and vibration accompanying water scooping of a rotary impeller includes a large-diameter blade divided into an inner blade and an outer blade. A radius of an impeller scooping up water is the sum of the lengths of the inner and outer blades in a radial direction. The large-diameter blade is divided at a position where the amount of generated air bubbles is large, and the inner and outer blades are alternately disposed. Accordingly, air bubbles are escaped to a downstream side in a rotational direction, so that the intensity of the collision between the blades and air bubbles is decreased reducing noise caused by the burst of air bubbles and vibration caused by a collision load of the flow of a gas-liquid mixture.

Abstract: A reservation registration apparatus, a method of reservation registration and a program storage medium allow reservation registration to be performed by easy operation. A starting time and an ending time can be set and changed by easy operation by displaying on a display screen reservation subject icons representing reservation subjects and a time base display area for performing reservation registration, and when the reservation subject icons are moved onto the time base display area, displaying a reservation time frame display division representing a starting time and an ending time of the reservation subjects according to positions to which they are moved, and changing a starting time or an ending time according to movement of the entire reservation time frame display division or movement of the first end or the second end of the reservation time frame display division.

Abstract: A motor includes a case which has a containing portion in which a rotor is contained, a bracket which closes an opening of the containing portion, the bracket having a through hole, and a conductive elastic member which is provided in the through hole. The conductive elastic member urges a conductive wire against an inner face of the through hole so as to fix the conductive wire.
