Abstract: A communication switch having heterogeneous ports. The heterogeneous ports are connected to nodes which may be operating at different frequencies and which may have different optical characteristics. In addition to the ports, the switch of the present invention includes a matrix controller and a matrix switch which is connected to the ports. When two ports want to communicate, the matrix controller commands the matrix switch to establish a physical connection between the ports. According to the present invention, data is transferred between the ports via the matrix switch in a serial and asynchronous manner. Because data is serially and asynchronously transmitted, high data rates through the matrix switch may be achieved.

Abstract: A method by which a task once set-up by the API is retained in an idle status after the task is complete. Set-up tasks are maintained in a pool. A task manager, in response to an application work request, initially searches the pool for an idle task (i.e., idle thread or process) corresponding to the task request. If there is a corresponding idle task in the pool, control passes to the application code for execution. If there is no idle task available, the Task Manager functions as an API and sets-up the task as in the prior art except that, when completed, it is not terminated but rather its identifier is placed in the pool.

Abstract: The invention relates to a process for recycling packaging materials containing one or more synthetic polymers and/or metal and/or natural polymers, with dissolution of the synthetic polymer component in a solvent and recovery of soluble and insoluble packaging constituents.   The object of the present invention is to develop an inexpensive and environmentally friendly process for recycling packaging materials containing one or more synthetic polymers and/or metals and/or natural polymers, in particular packaging composites. The disadvantages of the known processes are to be substantially avoided. In particular, the synthetic polymer component should be separated off in a manner suitable for recycling. The other components in packaging composites, such as the natural polymers present in cardboard (board) and paper, in particular cellulose, and metal, in particular aluminium, are likewise to be obtained entirely as individual components suitable for material recycling. This object is achieved according to the invention by a process in which the packaging materials to be recycled are treated with a solvent comprising aliphatic, naphthenic or aromatic hydrocarbons, hydrogenated products thereof or a mixture thereof. The solvent treatment is carried out until the synthetic polymer component has dissolved. The treatment temperature is between 0 and 500 DEG C. The solvents employed are, particularly, boiling fractions from primary and secondary petroleum refining whose boiling limits are in the range between 40 and 500 DEG C. The result of the treatment process is a liquid mixture of hydrocarbons of various structure and molecular weight in which the insoluble packaging constituents are dispersed. These insoluble packaging constituents, such as cellulose residues and aluminium, are separated from the liquid phase. The separation of the insoluble packaging constituents is followed according to the invention by the separation of the dissolved polymer component from the liquid mixture.

Abstract: A method and apparatus for determining whether a fluid, such as a refrigerant, is a liquid or a gas. To determine whether the fluid at a predetermined level ( 14 ) of a storage container ( 20 ) is a liquid or a gas, fluid is withdrawn from the container at the predetermined level, depressurized under conditions that would cause it to become a gas if it is a liquid before such depressurization, then the temperature of the fluid after depressurization is measured and compared to a reference temperature that is or is related to the temperature of the fluid in the container. If the temperature of the fluid after depressurization and the reference temperature are approximately equal, one can conclude that the fluid withdrawn from the predetermined level is a gas. If the temperature of the fluid after depressurization is considerably lower than the reference temperature, one can conclude that the fluid withdrawn from the predetermined level is a liquid. Such a determination can be used, for example, in order to shut down an apparatus ( 3 ) for transferring a refrigerant into a receiving container when the liquid level in the container reaches a predetermined maximum level.

Abstract: The optical method for analysing substances relies on the measurement of the propagation properties of optical surface waves on sensor surfaces. Light waves channelled through an optically conducting (wave-conducting) layer structure which is in contact with a sample are coupled out with a grating coupler. The coupling region of the grating coupler is formed by a spatial-resolution detector, so that the plane of the optically conducting layer structure forms the object plane and the detection plane lies in the image plane of the optical image formation. The light distribution of the wave field coupled out which results during image formation is measured using the detector and is used for determining the analytical measurement quantity. The device for implementing the method consists of a suitable optically conducting sensor (1, 2) with grating coupler (3), image formation optics (9) and an optical detector (10). <IMAGE>

Abstract: A process and system for sterilizing packages of thermally-treatable products having different sterilization processing requirements. These packaged products can be different types of canned soups, for example. At least one of the packaged products is preheated a significant, predetermined amount in a preheat vessel in a steam or steam-air mixture to accommodate these different processing requirements. This allows the first and second packages to be processed through the stationary hydrostatic sterilizer, which is generally separate from the preheat vessel, at a common line speed and temperature. Expensive sterilizer changeover delays are thereby reduced significantly or even avoided. This process also allows the soup to be cold blended, reducing the likelihood of any overcooking in the large cooking kettle and reducing the amount of starch needed.

Abstract: In a pulse width modulation amplifier used for acoustic reproduction apparatuses, an input side operational amplifier of a pulse width modulation amplifier is used as an alternating current amplifier by grounding its minus (-) terminal through a serial circuit formed of a resister and a capacitor. 
By this circuit constitution, the direct current gain of the operational amplifier becomes 1, and the offset voltage decreases until inherent offset voltage of the operational amplifier itself. Since the operational amplifier has no direct current coupling with next amplifying stage, it does not make worse the offset voltage after the operational amplifier, so the offset voltage of the final output stage becomes smaller. 
     Also, the negative feedback circuits connecting from the final output stage to the input of the operational amplifier include a low-pass filter whose capacitor is grounded and negative feedback signal is transmitted through a capacitor to the input of the operational amplifier so that direct current is cut. 
By this circuit constitution, the influence of the carrier and its higher harmonics and other noises leaked to the operational amplifier through the feedback circuit can be decreased.

Abstract: A semiconductor laser diode of a ridge type includes a double heterostructure in which a cladding layer (2) is formed in a mesa stripe form and a current block layer (8) which selectively buries mesa side and bottom surfaces of the cladding layer (2). For fabrication, a first step is to grow, sequentially above a substrate, a second cladding layer (3), an active layer (4), a first cladding layer (5) and a cap layer (6). A second step is to etch the first cladding layer (5) and the cap layer (6) respectively in mesa stripe forms. A third step is to selectively grow current blocking layer (7) on the first cladding layer (5) by a metalorganic vapor phase epitaxy process. A fourth step is to grow contact layers respectively on surfaces of the current blocking layer (7) and the cap layer (6). In the third step, a gas in which HCl is mixed in a concentration within a range of 0.2∼2 in a (HCl)/(III gas) ratio is used, which enhances re-evaporation of material on a selective mask. Thus, the protrusion formed in the current blocking layer (7) at each of the mesa side surfaces can be suppressed to a thickness not larger than 10% of a thickness of the current blocking layer (7) at its flat portion. In this way, the stress caused by lattice mismatch at the mesa side portions can be suppressed.
