A non-lasing superluminescent light emitting diode (SLED) comprises a semiconductor heterostructure forming a PN junction and a waveguide defining an optical beam path. The heterostructure includes a gain region and an absorber region in series with the gain region in the optical beam path. A voltage is applied to the PN junction in the gain region by first contact means, so that light emission from the active region and along the optical beam path is produced. According to the invention, second contact means are provided, contacting the PN junction in the absorber region and operable to remove charge carriers generated by absorption in the absorber region. The second contact means are not connected to a voltage source, but to a charge carrier reservoir such as a metal surface. According to a preferred embodiment, the two end facets of the waveguide are perpendicular to the optical beam path.

The present invention provides a fluorometric imaging apparatus for detecting the image of a specimen by irradiating excitation light at samples on the specimen arranged in a two-dimensional manner and measuring fluorescent light produced from a fluorescent substance attached to the specimen, the fluorometric imaging apparatus including: a two-dimensional photodetector device for detecting excitation light passing through the specimen or reflecting off the surface thereof; and movement means for repositioning the specimen according to images observed on the photoreceptor device.

The invention relates to a reactor driven in an oscillatory-rotary manner about its fixed, preferably vertical, axis, for preferably biotechnological and pharmaceutical applications. By means of its process-intensifying properties for mixing, suspension, gaseous material transport, heat transfer, irradiation and particle retention, the applicability on the industrial scale is ensured. The reactor which succeeds without a shaft seal permits particularly robust production with respect to sterile technique with avoidance of cleaning and cleaning validation required when the reactor is constructed as a single-use reactor.

The invention discloses a compound film used for an air-tight food-heating automatic pressure-regulating packing apparatus and a corresponding manufacturing method. The compound film is formed by a base film which is provided with a plurality of microcosmic clearance structure zones and on which an adhesive layer of an adhesive tape is coated to form a plurality of microcosmic clearance structure zones. The invention is especially used for various food packing boxes and bags, and after being packed and sealed, the food can be directly frozen in a sealed manner; when the food is to be cooked, the adhesive tape can be torn for a repeated use or the package containing the frozen food is directly put into a micro-wave oven for heating and the compound film is provided with the function of automatically regulating the high temperature and high steam pressure so as to prevent the explosion of the package in the heating process.

An antistaling agent for green grape is prepared from the durable antistaling agent of grape (described in the Chinese patent whose application number is 01137211.7), oxidant, alkaline substance and gas absorbent through respectively shaping and proportional mixing. It can keep the active concentration of SO2 in packing container for green grape.

Provided are a protective film and a manufacturing method thereof, in which the protective film includes a co-extruded film composed of an intermediate layer, and a first skin layer and a second skin layer present at both sides with the intermediate layer being disposed therebetween, wherein one or more layers of the first skin layer or the second skin layer contain polymer-based antistatic agents consisting of ethylene-based unsaturated carboxylic acids.

A cooking pot is composed of a main body made of Al alloy, a pig iron sheet wrapping part of all of said main body, and a coated layer. Said main body has a bottom with the slots for increasing the heat releasing area, projected parts, HF hot air channel and magnet installing grooves. Its manufacture technology includes such steps as casting said pig iron sheet, inserting it in a mould, pouring molten Al alloy, grinding, abrading, and coating. It has health-care function.

A grape freshness keeping method includes the following steps that 1, the opening of a freshness protection package is placed upwards, and two layers of absorbent paper are arranged at the bottom of the freshness protection package; 2, grapes are placed on the absorbent paper in the freshness protection package; 3, a layer of absorbent paper and a layer of freshness protection paper are sequentially placed on the uppermost side of the grapes, one side of the freshness protection paper is hydrophobic material and faces upward, and the other side of the freshness protection paper faces downward and is provided with preservatives; 4, the opening of the freshness protection package is sealed. Through the method, the surfaces of the grapes can be protected against moisture condensation and bleaching, definite humidity and definite concentration of the preservatives can be maintained in the freshness protection package, and the grapes are not prone to water loss and are kept fresh. Through the method, the pre-cooling step is omitted before the grapes are stored in a refrigeration house, and grape loss caused by complex steps in the grape storage process is prevented. In addition, operation steps are simplified, cost is saved, the relative humidity in the freshness protection package is high, stem protecting and green preserving are achieved, and bleaching of the preservatives is effectively reduced.
