  • Publication number: 20240139177
    Abstract: Disclosed are a method for producing an aripiprazole suspension, wherein the aripiprazole has a mean particle size of 1 to 10 ?m, the method comprising the steps of: (a) combining bulk aripiprazole and a vehicle to form a primary suspension; (b) subjecting the primary suspension to first pulverization using e.g., a high shear pulverizing machine, a dispersion machine that applies shear force to a material to be processed, a colloid mill, an ultrasonic dispersion machine, or a high-pressure jet type emulsifying dispersion machine to form a secondary suspension; and (c) subjecting the secondary suspension to second pulverization using e.g., a high-pressure jet type emulsifying dispersion machine to form a sterile final suspension; and a method for producing a freeze-dried formulation from the aripiprazole suspension.

  • Patent number: 11926184
    Abstract: In a riding work vehicle, power of an engine is transmitted to a traveling wheel via a horizontally oriented transmission shaft and a vertically oriented transmission shaft. The traveling wheel is supported to be changeable in direction about a rotational axis of the vertically oriented transmission shaft. Each of the vertically oriented transmission shaft and a vertically oriented transmission case is provided as an inner/outer double structure expandable/contractible in association with sliding movement thereof. The vertically oriented transmission case is supported to be pivotable together with the traveling wheel. There is provided a vehicle height adjustment mechanism capable of switching, in a plurality of steps, a relative height of the traveling wheel relative to a vehicle body frame.

  • Publication number: 20240077717
    Abstract: A scanning optical device includes a semiconductor laser, a coupling lens, a polygon mirror, a motor circuit board, a cable harness, and a scanning optical system. The semiconductor laser is configured to emit light. The coupling lens is configured to convert the light emitted by the semiconductor laser into a light beam. The polygon mirror is configured to deflect the light beam converted by the coupling lens. The motor circuit board includes a motor configured to rotate the polygon mirror. The cable harness is configured to supply signals to the motor circuit board. The scanning optical system is configured to receive the light beam from the polygon mirror and to form an image on an image surface. The cable harness overlaps the light beam directed from the coupling lens toward the polygon mirror when viewed from an axial direction of a rotation axis of the polygon mirror.

  • Patent number: 11579558
    Abstract: An image forming apparatus includes a housing having an opening, a cover movable between an open position and a closed position, a first photoconductive drum and a second photoconductive drum, a first exposing head having a first boss and rotatably coupled to the cover, a second exposing head having a second boss and rotatably coupled to the cover, and a cam rotatably coupled to each of the first exposing head and the second exposing head. The cam is configured to rotate each of the first exposing head and the second exposing head. The cam includes (i) a first elongated hole into which the first boss fits and extending a direction intersecting a movement direction in which the cam moves and (ii) a second elongated hole into which the second boss fits and extending in a direction intersecting the movement direction of the cam.

  • Patent number: 11333993
    Abstract: An image forming apparatus is disclosed which includes a housing, one or more drum cartridges, and one or more exposure heads. Each of the one or more drum cartridges includes a photoconductor drum and is installable in the housing. Each of the one or more exposure heads is configured to expose a corresponding photoconductor drum to light, and to be movable between an exposure position fit to expose the corresponding photoconductor drum to light and a retreated position away from the corresponding photoconductor drum. The housing has a groove through which to guide installation of the drum cartridge and in which to cause an exposure head in a corresponding exposure position to be located in place in a sub scanning direction.

  • Patent number: 10942484
    Abstract: A first joint rotatably couples a link member with a first exposure head unit. A second joint rotatably couples the link member with a second exposure head unit. A first rotation center of the first exposure head unit is closer to an end of a top cover than a second rotation center of the second exposure head unit is. The link member is configured to, when the top cover moves from a closed position to an open position, cause the first exposure head unit to rotatably move in a direction in which a first optical member approaches the end of the top cover and cause the second exposure head unit to rotatably move in a direction in which a second optical member approaches the end. A distance between the first rotation center and the first joint is larger than a distance between the second rotation center and the second joint.
