Abstract: A PCB includes a plurality of layers spaced apart in a vertical direction, a first detection pattern and a second detection pattern and pads connected to the first detection pattern and the second detection pattern. The first detection pattern and the second detection pattern are provided in a respective one of a first layer and a second layer adjacent to each other such that the first detection pattern and the second detection pattern are opposed to each other. The pads are provided in an outmost layer. Each of the first detection pattern and the second detection includes at least one main segment extending in at least one of first and second horizontal directions and a diagonal direction. A time domain reflectometry connected to a pair of pads detects a misalignment of the PCB by measuring differential characteristic impedance of the first detection pattern and the second detection pattern.

Abstract: The present disclosure provides a method for forming a three-dimensional memory device. The method can comprise forming a film stack with a plurality of dielectric layer pairs on a substrate, forming a channel structure region in the film stack including a plurality of channel structures, and forming a first staircase structure in a first staircase region and a second staircase structure in a second staircase region. Each of the first staircase structure and the second staircase structure can include a plurality of division block structures arranged along a first direction. A first vertical offset defines a boundary between adjacent division block structures. Each division block structure includes a plurality of staircases arranged along a second direction that is different from the first direction. Each staircase includes a plurality of steps arranged along the first direction.

Abstract: The present invention relates to an organic EL device having at least an anodic electrode, a hole transport layer, a light emitting layer, an electron transport layer, a cathodic electrode, and a capping layer in this order, in which the capping layer contains an amine compound having a benzazole ring structure represented by the following general formula (A-1).

Abstract: A supporter for electronic parts includes: an adsorption plate which is attached to an upper surface of a first electronic part among the first electronic part and a second electronic part where the first electronic part and a second electronic part are spaced apart from each other on a plane; and a supporting member which includes 1) a first support part which supports a lower surface of the second electronic part and 2) a connection part which connects the adsorption plate and the first support part. On the plane, about 70-90% of the area of the first support part is overlapped with the second electronic part.

Abstract: An organic light emitting display apparatus includes an organic light emitting display panel including a display area having a transparent area and an opaque area, and a non-display area. A gate driver is configured to sequentially supply a gate pulse to a plurality of gate lines included in the organic light emitting display panel. An initialization circuit is configured to transfer gate pulses or initialization control signals, output from the gate driver, to a plurality of transparent area gate lines. A camera is configured to photograph a region in a forward direction with respect to the organic light emitting display panel, and the camera may be provided in the transparent area of a rear surface of the organic light emitting display panel. A first pixel driving circuit provided in the transparent area may differ from a second pixel driving circuit provided in the opaque area.

Abstract: A self-locking device of an endoscope is provided. The endoscope includes a housing and a toggle assembly. The toggle assembly includes a toggle support, an elastic support and a toggle handle. The toggle handle is sleeved on the toggle support. An inner side of the toggle support is provided with a toggle lever and a friction piece. One end of the toggle lever is hinged to the toggle handle, and the other end of the toggle lever is not connected to the friction piece. The toggle lever has an L-shaped cross section, with a middle bend fixed to the toggle support. The toggle lever is hinged to the toggle support through a first pin. When being stressed, the toggle lever is rotatable around the first pin, so as to push the friction piece to move.

Abstract: An endoscope includes an insertion portion including a bending portion, an operation portion including an operation lever, a grasping portion including an actuator, and a tube body, in a continuous manner. When the operation lever is tilted, the actuator pulls a wire, whereby the bending portion is bent in a vertical direction and a lateral direction. The actuator is arranged such that a center of gravity of a portion including the insertion portion, the operation portion, the grasping portion, and the tube body is within a range in which at least one of the fourth finger or the fifth finger of the hand grasping the grasping portion is positioned, in a longitudinal direction of the grasping portion.

Abstract: A method for manufacturing an electronic device includes the steps of providing a flexible substrate, forming an electric circuit layer on the flexible substrate at an elevated temperature, and enhancing a transmittance of the flexible substrate after forming the electric circuit layer.
