Abstract: Virus-like particles (VLPs) of mammalian-hosted viruses, such as SARS-CoV and influenza viruses, have been recombinantly produced from Vero cells. The VLPs closely emulate the exterior of authentic virus particles and are highly immunogenic. They can elicit not only humoral but also cellular immune responses in a mammal. Compositions and methods related to the VLPs are also described.

Abstract: A multilayer substrate includes a base layer, a coating layer and an intermediate layer positioned between the base layer and the coating layer. The intermediate layer contains chromium and nitrogen. A content of the chromium in the intermediate layer gradually decreases from the base layer to the coating layer.

Abstract: An exemplary lens module includes a barrel receiving a lens system therein, an infrared-cut filter, an infrared-pass filter, and a switching mechanism. The switching mechanism includes a connecting member interconnecting the infrared-cut filter and the infrared-pass filter, a first magnetic member fixed at the barrel, and a second magnetic member fixed at the connecting member. The first and second magnetic members are configured for driving the connecting member to move relative to the barrel so as to selectively bring either the infrared-cut filter or the infrared-pass filter into optical alignment with the lens system in the barrel.

Abstract: An exemplary film coating holder includes a main body, a holding member, a first target electrode, a second target electrode and a driving module. The main body defines a chamber therein. The holding member receives in the chamber and has a plurality of through holes. The through holes being configured for receiving workpieces to be coated.

The driving member is disposed on the main body and mechanically coupled with the holding member, and configured for driving the holding member to rotate about a horizontally oriented axis, thus the first targeted material and the second targeted material can be respectively deposit on opposite sides of each of the workpieces.

Abstract: A support device used in sputtering machine includes a chamber housing, a frame, at least one holding device, a first and second driving assemblies. The frame is rotatably mounted in the chamber housing. The holding device is rotatably mounted on the frame. The first driving assembly is received in the chamber housing and includes a first motor mounted on the chamber housing and a first shaft installed on the first motor. The first driving assembly is configured for driving the frame rotating in a plane by the first shaft. The second driving assembly is received in the chamber housing and includes a second motor mounted on the chamber housing and second shaft installed on the second motor. The second shaft adjacently parallels to the first shaft. The second driving assembly is configured for driving the at least one holding device rotating in a plane perpendicular to the rotating plane of the frame.

Abstract: An exemplary street lamp for being stalled on the ground includes a light source, a light pervious member and a direction indicator. The light pervious member includes a light incident surface and an opposite light emitting surface for facing the ground. The light source is arranged opposite to the light incident surface. The direction indicator is arranged on the light pervious member for projecting the shadow thereof on the ground to indication a direction at the geographic location of the street lamp.

Abstract: A rolling machine includes a first clipping component, a second clipping component, a lifting component, and a holding assembly. The first clipping component has a first surface and a second surface opposite to the first surface. The second clipping component has a third surface configured to contact the first surface and a fourth surface opposite to the third surface. The lifting component is connected to the first clipping component and configured to drive the first clipping component to move back and forth. The holding assembly has a first and second holders configured to be symmetrically positioned on both sides of the first clipping component.

Abstract: The present invention relates to an automatic illuminating apparatus for motor vehicles. The apparatus includes an illumination device for emitting light beams, comprising a first light emitting member for emitting light beams in daytime and a controlling device electrically connected with the illumination device. The controlling device includes a sensor for sensing whether the vehicle is in motion, a time recording module for recording current time, a memory for storing an illumination period of the first light emitting member, a processor for analyzing whether the current time is in the illumination period which is electrically connected with the time recording module, the memory and the processor, and a controlling module for controlling the first light emitting member emitting light beams based on an analyzed result from the processor.

Abstract: A device for manufacturing lenses includes a tray, a cover, and a sheet. The tray defines supporting holes arranged in rows and columns. The cover defines through holes arranged in rows and columns. The sheet is positioned between the tray and the cover, and defines restricting passages. Each of the plurality of restricting passages corresponds to a column of corresponding supporting holes and a column of corresponding through holes.

Abstract: A tail light for an automobile includes a plurality of first illuminating elements and a plurality of second illuminating elements. The first illuminating elements are arranged to form a logo pattern of the automobile, and each of the first and second illuminating elements are configured for providing an adjustable illuminating brightness. The tail light is capable of selectively operating between a braking state and a non-braking state. In the braking state, the illuminating brightness of the first illuminating elements is greater than that of the second illuminating elements. In the non-braking state, the illuminating brightness of the first illuminating elements is less than that of the second illuminating elements.

Abstract: The present invention relates to an efficient microbial protein production system. A target protein is expressed as a portion of a fusion protein with the coat protein of Cymbidium mosaic virus (CyMV) in E. coli. Accordingly, the present invention provides nucleic acid expression vectors comprising a sequence encoding a protein of interest fused to CyMV coat protein, as well as methods of utilizing such vectors to produce the protein of interest.

Abstract: An oil collector for an upright smoke exhauster is provided, the oil collector includes an oil filter of predetermined mesh and attached at a lower circumference with a guide device which is prepared to introduce the oil from the filter into an oil cup at a lower portion of the exhauster. The filter is engaged into a circular vent in the housing of the smoke exhauster together with the guide device which has a tongue of an inverse isosceles triangle projected downward from an under side of a sloped portion thereof for facilitating the oil to be concentrated on the lower point of the triangle and dripped directly into the oil cup. The improvement has been characterized in the simple structure and greater efficiency in removal of the oil from the smoke exhauster.
