A projection system having a set of projectors that cast images: (i) onto the concave surface of a hemispherical dome, as is usual in planetariums and (ii) onto the surface of a centrally located sphere. The images thus cast may be coordinated by a controlling computer program, so that changes in the content or orientation of the images on the sphere result in corresponding changes in the images on the dome and vice versa.

A perforate projection screen for movies, planetariums and the like having inconspicuous seams and uniform reflectivity throughout its visible surface. The screen is made from a plurality of perforate panels and is mounted, when in use, with a dark non-reflective chamber behind the screen. Any overlapped areas of the panels and any frame members or other objects, in close proximity to the back of the panels are covered with a black velour type material to prevent light reflection from panel holes where objects are in close proximity to the back of the panel. The edges of adjacent panels overlap to form seams with the overlapped edges of the panels being crimped to form recesses to receive the overlapping edge strip of an adjacent panel, thereby hiding the overlapping panel edge to reduce shadow lines and make the panel edges inconspicuous to viewers.

Light emitted from a light source passes through a stellar base plate, a fixed aperture, and a wide-angled projection lens via a condenser lens and projects a starry sky on a screen. The stellar base plate is a light-shielding disk having a number of through holes which correspond to positions and brightness of actual stars, is supported by an inner ring of a ball bearing having the center at a position corresponding to the axis of rotation so as to be capable of rotating about the axis of rotation, and is driven by a motor via a belt. The centers of the projection lens, a window of the fixed aperture, the condenser lens, and the light source are all arranged on the optical axis, and the centers of the stellar base plate, the pulley and the ball bearing correspond to the axis of rotation.

The invention relates to a method for controlling a planetarium to demonstrate astronomical phenomena and a control system. The planetarium comprises a controller and a touch-sensitive display. The method comprises the following steps: presetting a control command in the controller; displaying a plurality of graphic blocks which are arranged in a queue on the touch-sensitive display, wherein eachgraphic block is matched with one or more of the plurality of control commands; detecting contact with the touch-sensitive display at the position corresponding to one graphic block in the queue; keeping contact movement during continuous contact with the touch-sensitive display, and making a corresponding contact graphic block move in a following manner; when the graphic block following contact movement is moved to the head end and the tail end of the queue or a preset insertion range in which any two adjacent graphic blocks do not intersect with each other, detecting the disappearance of contact, and inserting the graphic block into a queue position corresponding to the insertion range; detecting the contact in a preset starting area on the touch-sensitive display and the disappearance of the contact, and transmitting a demonstration request to the controller in order to start the planetarium to demonstrate the astronomical phenomena according to the queue sequence.

It is intended to provide a digital planetarium picture-projecting apparatus capable of recording and executing an operation procedure, facilitating recording of the operation procedure, editing the operation procedure, and executing an ad-lib representation when the operation procedure is executed. The digital planetarium picture projecting apparatus comprises an operating portion which accepts an operation by an operator about picture projection, an operation display panel which displays information about picture projection to the operator, a manual process recording portion which records an operation procedure executed to the operating portion, and a control portion which executes picture projection according to the operation procedure recorded in the manual process recording portion, wherein a temporary stop or restart operation by the operator is accepted during recording of the operation procedure by the manual process recording portion. Further, information about a projection screen is displayed on an operation display panel during execution of picture projection according to the operation procedure.

A projection system having a set of projectors that cast images: (i) onto the concave surface of a hemispherical dome, as is usual in planetariums and (ii) onto the surface of a centrally located sphere. The images thus cast may be coordinated by a controlling computer program, so that changes in the content or orientation of the images on the sphere result in corresponding changes in the images on the dome and vice versa.

A digital planetarium apparatus includes an original image generator, an intermediate image generator, and a fish-eye lens. The original image generator is formed of two video projectors and generates semicircular images in display devices inside the respective video projectors. The intermediate image generator optically focuses the two semicircular images generated by the original image generator to thereby generate a circular image. The fish-eye lens projects the circular image generated by the intermediate image generator.

A projection system having a set of projectors that cast images: (i) outwards onto the concave surface of a hemispherical dome, as is usual in planetariums and (ii) inward onto the convex surface of a centrally located sphere. The images thus cast may be coordinated by a controlling computer program, so that changes in the content or orientation of the images on the sphere result in corresponding changes in the images on the dome and vice versa.

The invention discloses preparation process for fermented chilli sauce. The preparation process includes the following steps: placing fresh chilli and ginger into a jar, mixing cultures of lactobacillus planetarium and fermentation lactobacillus, and conducting three times of culture cultivation to obtain fermentation broth; adding the fermentation broth and fermenting; taking the chilli and ginger out of the jar and pulping; stirring and seasoning; packaging the fermented chilli sauce with tins or toothpaste-tube-shaped jars for replacing the jars and vacuum-sealing; and sterilizing through heat to obtain finished products. The chilli sauce is produced through pure-culture fermentation, calcium lactate and calcium chloride are used as a hardener, and color protecting processing is conducted by using 0.1% erythorbic acid combined with 0.1% laurel kojic acid. Simultaneously, the chilli sauce is packaged by using the tins and toothpaste-tube-shaped cans and has the advantages of being short in fermenting time, low in nitrite content, stable in product quality and good in product appearance quality.
