A gear device which vibrates less and emits less noise. The gear device has a first gear provided to a first shaft, a second gear provided to a second shaft and meshing with the first gear, and a third gear provided to a third shaft and meshing with the second gear. The second gear has formed therein through-holes extending in the circumferential direction about the rotation axis of the second gear, and this changes the circumferential rigidity of the second gear. The first and third gears are arranged such that the rigidity of the second gear at certain time at the point of meshing between the first and second gears and the rigidity of the second gear at the point of meshing

A developer cartridge including a frame, a developer housing section, a developer supplying section, a developer electrode, and an input gear is provided. The frame includes a first side wall and a second side wall, and the first side wall and the second side wall extend substantially in a length direction. The developer housing section, for housing a developer, extends from the first side wall to the second side wall in a width direction substantially perpendicular to the length direction. The developer supplying section, for supplying the developer to a photosensitive member, extends from the first side wall to the second side wall in the width direction and houses a developer carrying member. The developer carrying member includes a developer carrying member shaft and a developer carrying member body that is supported on the developer carrying member shaft. The developer carrying member shaft extends in the width direction and is rotatably supported by the first side wall and the second side wall. The developer electrode electrically biases the developer carrying member, and at least a portion of the developer electrode is connected to the first side wall and the developer carrying member. The input gear supplies a driving force for rotating the developer carrying member.

A three-dimensional object is made by repeating a process. An optical beam is irradiated on a predetermined portion of a powdery layer to form a sintered layer. A new powdery layer is formed on a surface of the sintered layer. An optical beam is irradiated on a predetermined portion of the new powdery layer to form a new sintered layer united with the underlying sintered layer. Because a portion of the sintered layer that is higher than a predetermined level is removed as occasion demands, the abnormally sintered portion on the sintered layer can be removed, making it possible to prevent stoppage of the shaping process, which may be caused by the abnormally sintered portion.

The invention relates to a liquid crystal display panel 2 including a first base having a light shielding film 45, color filters 46R, 46G, 46B, 46, and a first display electrode 48 on a first transparent substrate 4; a second base 5 having a second display electrode 51 on a second transparent substrate 50, spacers 20 and 21 for keeping a distance between the first and the second bases 4 and 5; and a sealing member 6 for sealing a liquid crystal between the first and the second bases 4 and 5. At least one of the first and the second bases 4 and 5 includes a convex portion 43 between a display region 40 including display pixels and a sealing region 41 sealed by the sealing member 6, to enclose the display region 40 with the convex portion 43. The spacers 20 and 21 include a first spacer 20 in the display region 40 and a second spacer 21 on the convex portion.

It is an object of the present invention to provide a liquid crystal display panel having a high contrast ratio in a front direction.A liquid crystal panel according to an embodiment of the present invention includes: a liquid crystal cell; a first polarizing plate placed on one side of the liquid crystal cell; a second polarizing plate placed on the other side of the liquid crystal cell; and a retardation layer placed between the liquid crystal cell and the second polarizing plate. A refractive index ellipsoid of the retardation layer exhibits a relationship of n≧ny>nz; and a light transmittance (T2) of the second polarizing plate is larger than a light transmittance (T1) of the first polarizing plate. Such a liquid crystal panel has a remarkably higher contrast ratio in a front direction than that of a conventional liquid crystal panel (for example, a liquid crystal panel in which the light transmittances of two polarizing plates placed on both sides of a liquid crystal cell are the same), and shows excellent display properties.

A rotary compressor includes a compression mechanism, an electric motor and a controller. The compression mechanism includes a piston and a cylinder having two cylinder chambers. The electric motor is configured to change volumes of the cylinder chambers by eccentrically moving the cylinder and the piston relative to each other. The controller is configured to change an output torque of the electric motor in accordance with a variation in a load torque of the compression mechanism in one turn of rotation.

A rotary fluid machinery includes a fixed member, a drive shaft driven and rotated about a rotation axis, a movable member, a movable member support part and a reverse moment generating mechanism. The movable member is rotatably mounted at the drive shaft with its center being eccentrically disposed relative to the rotation axis, with the movable member and the fixed member forming a fluid chamber. Revolution of the movable member changes the volume of the fluid chamber. The movable member is configured to swing in association with its revolution. The reverse moment generating mechanism generates a moment in a reverse direction about the rotation axis relative to a moment about the rotation axis caused by the revolving movement of the movable member.

In the image-forming device, the second driving force is transmitted from each input coupling to the corresponding output coupling to rotate the corresponding photosensitive drum when each input coupling is positioned at a predetermined position for the corresponding output coupling. The first detecting unit and the second detecting units detect a position of each input coupling and a position of each output coupling respectively before the first driving unit begins to provide the first driving force and the second driving unit begins to provide the first driving force. The calculating unit calculates, based on the position of each input coupling and the position of each output coupling, a first start timing when a first photosensitive drum starts to rotate and a second start timing when a second photosensitive drum starts to rotate. The controlling unit controls the first driving unit to begin to provide the first driving force after the first start timing and before the second start timing.

A guide body for guiding the back surface of toner-image-bearing paper is formed from an insulating material and is disposed so as to face a paper transport path. A paper-transport-path-facing portion of the guide body, which faces the paper transport path, has guide ribs projecting upward toward the paper. A covering metal sheet is configured such that a covering portion thereof partially covers a guide surface of the paper-transport-path-facing portion which faces the paper transport path. The covering metal sheet has slits formed therein and corresponding to the guide ribs. The slits allow the guide surface to be partially exposed therethrough.
