A coupling system for detachably coupling an outlet port of a submergible pump to an inlet port of a discharge conduit is constructed by a single guide rail having at least two, and preferably, two guide portions extending along the length thereof, the rail being fixed at its lower end to the conduit; an arm attached to the pump so that it is guided by the rail; and first and second engaging means provided in the discharge conduit adjacent the inlet port and in the arm respectively so that the pump is held stationary when the pump is lowered and both the engaging means engage with each other. The whole system is made compact by arranging the orientation of the guide rail particularly when it is made of an angle bar. Also, further consideration is given to effect a line contact between the first and second engaging means to reduce the severe manufacturing tolerance necessary to achieve a satisfactory coupling between the inlet and outlet ports.

An improved grinder pump of the water immersed type is disclosed which includes a motor driven semi-open type pump impeller, a grinder ring fitted and firmly mounted in the suction port at the bottom of the pump casing, the grinder ring being provided with a plurality of axially extending grinding grooves and edges on the inner surface thereof, and a grinder impeller fixedly screwed on the distal end of the pump shaft to be coupled to the pump impeller in an end-to-end relation, the grinder impeller being provided with at least two axially extending grinding blades provided on the lower conical surface of the hub thereof so that any foreign material contained in the pumping liquid is ground or shredded into smaller pieces by cooperation of the grinding edges of the grinder ring with the grinding blades of the grinder impeller. A plurality of radially extending auxiliary blades are provided on the upper surface of the hub of the grinder impeller so as to perform additional pumping and grinding operation. The grinding blades protrude downwardly beyond the bottom of the grinder ring to provide the additional effect of ensuring to prevent foreign material in the pumping liquid from directly entering the grinding grooves from the suction port and foreign material is subjected to repeated shredding by the agitation of the grinding blades.

According to one embodiment, an interface apparatus for displaying a GUI object according to a position and a direction of a pointing object comprises a display unit, an image capturing unit, a detection unit, and an additional display unit. The display unit displays a movie based on a first image frame group. The image capturing unit obtains a second image frame group by capturing an image of a surface on which the movie is displayed. The detection unit detects a position and a direction of the pointing object based on the first image frame group and the second image frame group. The additional display unit displays a specific shape which is superimposed to the first image frame group, so that the detected position of the pointing object is irradiated with light of no less than a predetermined illuminance and the light attenuates according to a distance from the position.

According to one embodiment, a content summarizing apparatus includes a selection unit, a record unit, and a storage unit. The selection unit selects at least one image from input content in accordance with at least one selection criterion and at least one parameter corresponding to the at least one selection criterion, and to produce a summary. The record unit cause the storage unit to store a summary record information item that includes the at least one selection criterion and the at least one parameter used by the selection unit. The storage unit stores the summary record information item whenever the summary of the input content is produced. The selection unit acquires past summary record information items from the storage unit, and produces the summary using the at least one selection criterion and the at least one parameter that fails to be included in the past summary record information items.

A face recognition apparatus includes an image sequence acquiring unit, a face image acquiring unit, an intra-sequence classifying unit, an inter-sequence classifying unit, an identification unit, and a reference image storing unit. A plurality of cameras are attached in a corridor for monitoring one place with these cameras, so that when a plurality of moving people pass through, identification is performed for each moving people. Face images are classified into fragmental face image sets, and the fragmental face image sets are classified into integrated sets to achieve the identification.

A gear portion is provided on the inner peripheral surface of a dial, and a large diameter portion of a main driving gear is mated with the gear portion. A driven gear is mated with a small diameter portion of the main driving gear, and the state of an air conditioner is switched based on the moving operation of a cable through the gear portion, the main driving gear and the driven gear in the rotating operation of the dial. With this structure, it is not necessary to provide a rotary shaft as a member for transmitting an operating force to the central part or the dial. Consequently, it is possible to maintain a space in the central part of the dial. Thus, restrictions can be decreased in the case in which a knob is to be arranged.

Disclosed is a sewing machine having a horizontal sewing table, an X-direction frame drive portion and a Y-direction frame drive portion, which are disposed downward of said sewing table, and a long frame drive member disposed upward of said sewing table, which is freely movable on the X and Y coordinates surface by both the frame drive portions. A guide member long in the Y direction is provided so as to be horizontally located upward of the intermediate position in the X direction at the frame drive member. A moving member disposed at this guide member so as to be movable in the Y direction is movable integrally therewith in the Y direction relative to the frame drive member and is connected thereto so as to be relatively movable in the X direction. A sub drive mechanism is able to move the moving member in synchronization with the drive of the Y-direction frame drive portion.
