The device includes a non-magnetic sleeve (4) for carrying the magnetic developer (2), a resin magnetic stationarily disposed in the sleeve, the magnet being of a mixture of a resin material and a magnetic material, and extending in the direction of a length of the sleeve. The magnet has first and second magnetic field generating portions. First (3) and second (8) magnetic members are disposed outside the sleeve (4) extending in the direction of the length of the sleeve. The first (3) and second (8) magnetic members are spaced apart from each other and are so disposed that a magnetic force applied to the magnet by a magnetic force between the first magnetic field generating portion and the first magnetic member reduces a resultant force to the magnet by gravity and by a magnetic force between the second magnetic field generating portion and the second magnetic member.
摘要:
The variable focus lens (100) of the present invention changes the refractive power by changing each of the shapes of a first interface (107) formed by a first liquid (101) and a second liquid (102) that have refractive indices that differ from each other and a second interface (108) formed by the second liquid (102) and a third liquid (103) that have refractive indices that differ from each other. Thereby, this variable focus lens (100) changes the first interface (107) and the second interface (108) such that the sign of the refractive power of the first interface (107) and the sign of the refractive power of the second interface (108) differ from each other.

A liquid discharge head (3) includes discharge orifices (13), recording elements (15) generating energy, multiple supply channels (213) supplying liquid to the recording elements (15), common supply channel (211) communicating with the multiple supply channels (213), recovery channels (214) recovering liquid supplied to the recording elements (15), common recovery channel (212) recovering liquid from the recovery channels (214), first inlet port (7a) supplying liquid to the common supply channel (211), first recovery port (8a) recovering liquid from the first common supply channel (211), second inlet port (7b) supplying liquid to the common recovery channel (212), and second recovery port (8b) recovering liquid from the second common recovery channel (212). The first inlet port (7a) and the first recovery port (8a) communicate without going through channel portions where recording elements (15) are disposed, as do the and the second inlet port (7b) and the second recovery port (8b).
摘要:
A method for manufacturing a flow passage assembly includes forming a first flow passage (406A, 407A) in a first joint interface formed by welding a first surface of a first flow passage forming member (401) to a first surface of a second flow passage forming member (402) by ultrasonic welding and forming, after the first flow passage (406A, 407A) is formed, a second flow passage (411) in a second joint interface formed by welding a first surface of a third flow passage forming member (410) to one of a second surface of the first flow passage forming member (401) and a second surface of the second flow passage forming member (402) using an ultrasonic welding process. A total area of weld portions (414) used when the first flow passage is formed is greater than a total area of weld portions (415) used when the second flow passage is formed.
