Abstract: Formed in a wall part of a dome part of an annular combustor encircling an axis of a gas turbine engine are multiple fuel supply holes spaced at predetermined intervals in circumferential direction around the axis and many cooling holes extending through the wall part in direction inclined to a normal thereof. When two adjacent fuel supply holes are defined as first and second fuel supply holes, a virtual boundary line contacting an outer semi-circular portion, far from the axis, of the first fuel supply hole and an inner semi-circular portion, close to the axis, of the second fuel supply hole is set. The first cooling holes in region radially outward, relative to the axis, of the line are inclined toward the second fuel supply hole, and the second cooling holes in region radially inward, relative to the axis, of the line are inclined toward the first fuel supply hole.

Abstract: A quantum dot protective film for sealing a phosphor, including: a protective layer having foreign matter, the maximum size of which is 100 to 500 ?m; and a coating layer formed on one surface of the protective layer, wherein the abundance ratio of the foreign matter with the maximum size of 100 to 500 ?m is 0.01 to 5.0 particles/m2 in the protective layer, and the haze value is 20% or higher.

Abstract: A toner container is attachable to and detachable from a toner supply portion of an image forming apparatus. The toner container includes an attaching portion configured to be engaged with an attached portion of the toner supply portion such that the toner container is selectively attached to the toner supply portion. The attached portion includes an engaged portion around which first interruption keys are disposed. The attaching portion includes an engaging portion and a plurality of key members. The engaging portion is configured to be engaged with the engaged portion. The key members are larger in number than the first interruption keys and include second interruption keys formed in correspondence with the first interruption keys. Among the key members, the second interruption keys that interrupt with the first interruption keys are cut so that the engaging portion and the engaged portion can be engaged with each other.

Abstract: A toner case includes a case main body, a housing frame, a communicating port, a conveying rib, and a conveying screw. The case main body is capable of containing a waste toner. The housing frame is configured to communicate with an inside of the case main body and to rotatably support the case main body. The communicating port is opened on a circumferential face of the housing frame and connected with an image forming part. The conveying rib rotates integrally with the case main body in a first direction so as to convey the waste toner along a direction of introducing the waste toner into the case main body. The conveying screw rotates integrally with the case main body in the first direction so as to convey the waste toner introduced into the housing frame via the communicating port toward the inside of the case main body.
