    摘要: An additional cornea projection device for ophthalmic slit lamp microscope, comprising: a cornea projection device, a slit lamp microscope optical body, a curved arm and the connecting part. The cornea projection device is connected to the upper or lower part of the optical body of the slit lamp microscope, or to the left or right side of the curved arm. When the cornea projection device is not in use, it can be rotated to a non-working position while being kept connected, and there is no obstacle to the normal use of the slit light source projection device of the ophthalmic slit lamp microscope. An ophthalmic slit lamp microscope with a cornea projection device has a simple overall structure, reliable performance, low cost, obvious advantages, convenient for production, debugging and maintenance.

    摘要: A coating material with a primer layer, a middle layer and a surface layer and its method of application which includes the steps: (1) spraying the primer layer material onto an article; (2) spraying or brushing the middle layer material with a first color until satisfactorily coated; (3) repeating step (2) with the middle layer material having a second color and allowing drying; and (4) spraying the surface layer material of PU imitation porcelain material and allow drying to obtain the article with superior imitation ceramic effect. The present invention can be applied to any plastic and poly articles with a contoured body, making a highly imitative ceramic article such as pot or vase to replacing the existing authentic ceramic articles. Since the material being used is biodegradable, therefore effectively decreasing the level of pollution and damages to the environment and hence lessening the health hazards to human.

    摘要: A sound producing apparatus with multi-directivity has two or more speakers to produce music or other types of audio sounds. Each of the speakers can produce audio sounds in a certain direction and at least one speaker is steerable so that its sound propagation direction relative to the others can be changed. Furthermore, one or more speakers can produce audio sounds in an adjustable angular range. One or more of the speakers can be dual-mode speakers, each of which can be operated as a wide-angle speaker or a narrow-angle speaker. With multi-directivity, it is possible to play one type of music in one direction and another type of music in another direction to suit the interests of the audience. The apparatus can be a mobile phone, an audio player, a digital or analog recorder/player, or the like.
