Abstract: A phase change random access memory (PCRAM) device includes a memory cell overlying an inter-metal dielectric (IMD) layer, a protection coating, and a first sidewall spacer. The memory cell includes a bottom electrode, a top electrode and a phase change element between the top electrode and the bottom electrode. The protection coating is on an outer sidewall of the phase change element. The first sidewall spacer is on an outer sidewall of the protection coating. The first sidewall spacer has a greater nitrogen atomic concentration than the protection coating. The protection coating forms a first interface with the phase change element. The first interface has a first slope at a first position and a second slope at a second position higher than the first position, the second slope is different from the first slope.

Abstract: A display method and a display system for an anti-dizziness reference image are provided. The display system includes a display, a range extraction unit, an information analyzing unit, an object analyzing unit and an image setting unit. The display is used to display the anti-dizziness reference image. The range extraction unit is used to obtain a gaze background range of a user. The image setting unit is used to set an image hue, an image lightness, an image brightness, an image content or an ambient lighting display content of the anti-dizziness reference image according to a background hue information, a background lightness information, a background brightness information, or a road information of the gaze background range; or set an image ratio between the anti-dizziness reference image and a display area of the display according to an object distance or an object area of the watched object.

Abstract: The present disclosure describes compositions and methods for preparing membrane protein nanosheets and two-dimensional crystals. In particular, the methods employ a solvent. A mixture of a polymer and a membrane protein is solubilized in the solvent, applied to a substrate, and subsequently dried to form the nanosheet or two-dimensional crystal. Applicants have surprisingly found that the membrane proteins maintain their structure when exposed to solvents during the short processing time utilized.

Abstract: An elevation-type armrest includes a driving assembly and a cushioning assembly. The driving assembly includes a worm, a crank, an axle, a shaft, a worm gear, two toothed wheels and two pinions. The crank is connected to the worm. The axle extends perpendicular to the worm. The worm gear is connected to the axle and engaged with the worm. The first toothed wheel is connected to the axle. The shaft extends parallel to the axle. The second toothed wheel is connected to the shaft and engaged with the first toothed wheel. The pinions are connected to two ends of the shaft. The cushioning assembly includes a supporting tube connected to two racks. Each of the racks includes a toothed portion movably located in a corresponding one of the cylinders and engaged with a corresponding one of the pinions.

Abstract: A hair cleaning device includes a handle, a rotation cylinder pivotally connected to the handle, a turning seat and a blade seat. The rotation cylinder has a coupling portion on an outer wall thereof to receive a roll of adhesive tape thereon. The turning seat is disposed at one side of the rotation cylinder close to the handle. The turning seat has a press portion which is axially disposed above the rotation cylinder. The blade seat is slidably connected to the press portion of the turning seat. The hair cleaning device of the present invention uses the roll of adhesive tape to clean hair, cotton fiber or dust with ease and can be operated conveniently.

Abstract: A measuring compass is disclosed. The compass comprises a marking leg, a pegging leg which symmetrically form into a shape of a pencil. The upper end of the pegging leg and the marking leg is a center plate or gear module, and the bottom end is a protective cover for protecting the marking leg and the pegging leg. When the compass is not in use, the marking leg and the pegging leg are closed to each other and the protective cover caps the legs. The compass can be inserted to a pocket.
