The present invention provides a print head that ejects ink supplied through an ink supply port so as to prevent the size of satellites from being reduced while inhibiting an increase in resistance to an ink flow. In the print head, ink supply ports are arranged on both sides of a plurality of channels. A predetermined number of ink supply ports are arranged at least one side of the ink channel all over the range of the arrangement of the channels. One side of each of the plurality of channels is connected via the common liquid chamber to the liquid supply port located so as to extend in a direction in which the channels are arranged.

A liquid ejection head includes ejection orifices allowing liquid to be ejected therethrough, passages communicating with the ejection orifices and the pressure chambers each accommodating an energy generating element generating energy for ejecting the liquid therein, a supply port supplying the liquid to the passages, and a filter including substantially cylindrical members between the supply port and passages and having openings. Each of the ejection orifices has a substantially circular cross section having larger and smaller diameters substantially perpendicularly to its liquid ejecting direction. Each of the openings has a substantially rectangular cross section having longer and shorter sides substantially perpendicularly to its liquid supplying direction. The relationships D1>L1, D1 L2≧D1 are satisfied where D1 is the smaller diameter, D2 is the larger diameter, L1 is the shorter side, and L2 is the longer side.

A depilatory device in this invention comprising a housing, a plucking means, a pinching mechanism, and a plucking mechanism. The plucking means includes a plucking cylinder which is supported to the housing. The plucking cylinder carries a plurality of pinching units at a circumference surface of the plucking cylinder. The pinching unit is composed of a first blade and a second blade. At least one of the first blade and the second blade is movable toward and away from the other of the first blade and the second blade to have an opened position and a pinch position. Each of the pinching units has a hair introducing direction perpendicular to the gap between the first blade and the second blade in the opened position. The pinching mechanism is configured to provide the opened position and the pinch position to the first blade and the second blade. The plucking mechanism is configured to rotate the plucking cylinder. The pinching units are arranged to have their hair introducing directions which are inclined with respect to the longitudinal axis as well as a circumferential direction of the plucking cylinder.

A compact liquid ejection recording head capable of forming high-quality images at high speed includes large nozzles for ejecting large droplets, medium nozzles for ejecting medium droplets, and small nozzles for ejecting small droplets. The large nozzles are arranged on one side of an ink supply port, while the small nozzles and the medium nozzles are arranged on the other side of the ink supply port. The number of the small nozzles is larger than that of the medium nozzles, and that of the large nozzles. This allows high-quality and high-speed printing using the small nozzles, high-speed photo printing using the medium and small nozzles, and high-speed printing using the large nozzles.

A shaving head for a dry shaver is capable of increasing the cutting efficiency, yet allowing the use of the inner cutter of simple structure. The shaving head has a slit cutter unit composed of an outer cutter shaped to have a top surface for contact with a user's skin, and an inner cutter in contact with a bottom surface of the outer cutter. The outer cutter has a U-shaped structure with a pair of legs connected by a crossbar, and to have a plurality of slits which are spaced in a lengthwise axis of the outer cutter to leave a plurality of bridges each between the adjacent ones of the slits. The slits extend continuously over a full width of the crossbar and into upper ends of the legs in a direction generally perpendicular to the lengthwise axis, giving two straight slit paths respectively on opposite width ends of the outer cutter. The straight slit paths on the opposite width ends are staggered with respect to each other along the lengthwise axis. Each of the bridges extends along the width axis of the outer cutter to make the bottom surface of the outer cutter smoothly continuous over the full length of the bridge, and that each bridge is formed at its longitudinal center with a deflection which is angled with respect to the width axis so as to leave, between the adjacent ones of the deflections, an angled path through which the straight slit paths of each slit extends continuously.

A motor of this invention is provided with a sleeve-type bearing impregnated with oil for supporting a rotor assembly including a shaft and a rotor member. A lower face of the rotor is provided with at least two peripheral wall portions, an inner peripheral wall portion and an outer peripheral wall portion, which surround the shaft with a gap therebetween in a radial direction. The peripheral wall portions are accommodated in an annular recessed portion so as to surround an open space over a sleeve constituted the sleeve-type bearing and has a lower top of the most inner part. The lower end of the inner peripheral wall portion is located lower than the lower end of the outer peripheral wall portion, and the lower end of the outer peripheral wall portion is located lower than the lower top of the annular recessed portion.
