Inventor: MILLER JEREMY PAUL
IPC: B05B1/34
Filed: 1994-02-15
Abstract: A tunnel freezer (1) is cooled by selectively supplying liquid nitrogen to banks (5,6,7) of spray nozzles. The banks (5,6,7) are switched on and off as required so that at any given time the pressure upstream of each operational spray nozzle will be substantially constant at a level which closely approximates the maximum heat transfer coefficient associated with the spray nozzle or the maximum effectiveness of the spray nozzle or a balance therebetween.

Abstract: The invention shows a spraying gun (1, 2) and a paint container (7) for applying paint in hobby work, model construction and similar painting or leisure purposes. By means of an air flow, an air/paint mixture is produced. The paint carrier (12), e.g. a wick, is held by the paint container (7) which is preferably designed in the manner of a cartridge and can be introduced into the spraying gun (1, 2). In order to achieve the fact that the paint container is automatically secured outside the spraying gun against unintentional emergence of paint, provision is made by means of the invention for the paint container (7) to have a closure (15) which, when the paint container is situated outside the gun (1), in its closing position covers the region of the paint carrier which delivers the paint to the air flow, for interacting means (10, 11; 16, 17) to be provided on the one hand on the paint container and/or on the closure and on the other hand on the inner region of the gun (1, 2) receiving the paint container, which means remove the closure (15) from its position closing the paint-delivering region of the paint carrier automatically with the introduction of the paint container into the spraying gun and clear the path of the air flow over this region and, when the paint container is taken out of the gun, bring the closure back into its position closing the paint-delivering region of the paint carrier. The invention furthermore relates to a spraying gun and to a paint container. <IMAGE>

Abstract: There is a wish to offer a video-on-demand service, in addition to the cable television service, to subscribers of a cable television distribution network. Since the optical fibre portion of the cable television distribution networks will not reach the subscribers (111) in the foreseeable future but will end in optical network terminations (ONTi) and will be continued from there to the subscribers in each case through an optical access network (108-110), the problem is how the totality of subscriber-individual video signals can be transmitted to subscribers so that these can receive the video signals in each case requested. According to the invention, the transmission takes place digitally in time-division multiplex and wave-division multiplex from the centre (100) via the optical fibre distribution network (101-107) to the optical network terminations (ONTi). In each optical network termination, only the part of subscriber-individual video signals which is intended for subscribers which are connected to the optical network termination (ONTi) is removed. The removed subscriber-individual video signals are modulated onto subcarriers (N1-M6) and are added in frequency-division multiplex to the cable television signals which are distributed via the electrical access network (108-110) to the subscribers (111) connected to the optical network termination (ONTi). <IMAGE>

Abstract: The present invention relates to a field effect transistor with high speed and excellent high frequency characteristics. A hetero junction field effect transistor, comprising a first semiconductor layer that contains In, a second semiconductor layer that contains In whose composition ratio is smaller than that of the first semiconductor layer, and a third semiconductor layer whose electron affinity is smaller than that of the first semiconductor layer, wherein the first semiconductor layer, the second semiconductor layer, and the third semiconductor layer are successively disposed in the order, and wherein the thickness of the second semiconductor layer is equal to or larger than the thickness of two monolayers thereof and less than 4 nm. A current of this field effect transistor flows in the first semiconductor layer 3 and the second semiconductor layer 4 of the transistor. When the thickness of the second semiconductor layer 4 is 4 nm or more, the ratio of electrons that exist in the first semiconductor layer 3 is 85 % or less of the case that the thickness of the second semiconductor layer 4 is almost zero. Thus, when the thickness of the second semiconductor layer 4 is decreased to the thickness of two monolayers thereof, the ratio of electrons that exist in the first semiconductor layer 3 becomes nearly 100 %. Consequently, the high frequency characteristics of the transistor are improved.

Abstract: A surround signal processing apparatus is proposed whereby, in the reproduction of surround sound based on a monaural rear surround signal input, where a sound image localization process is used, good surround sound field control is achieved by minimizing the correlation between the left and right rear sound signals. The result is natural surround sound in which the listener perceives a sense of expansiveness. 
     In addition to performing the signal processing required to render mutually non-correlative, a left-right pair of rear surround signals based on a monaural rear surround sound signal input, the apparatus also performs the signal processing required to localize sound images to locations behind and substantially laterally symmetrical with respect to a listener, based on input of a left-right pair of rear surround signals that have been signal processed.

Abstract: A power pump for use in a brake fluid pressure controller as its power source. It is provided with an economical means for reducing hammering noise. It has a pump-driving motor coupled to a pump housing and having an output shaft supported on a bearing provided outside a motor housing. In order to suppress whirling of the output shaft of the motor, which is a major cause of hammering noise, the bearing is supported on the pump housing by inserting it partially into a straight hole formed in the pump housing. This make it unnecessary to fit the bearing in the motor housing with so high accuracy, so that the recess for receiving the bearing can be formed in the front cover of the motor housing by a simple and economical method. Thus, it is possible to reduce hammering noise economically.

Abstract: An amplitude limiting circuit (20) is utilized to select the most favorable linear region of the light vs. current characteristic curve (for directly modulated lasers (22)) or the laser's modulator transfer function (for externally modulated lasers) by preventing excursions of the broadband, multiplexed input signal (I m  (t)) beyond selected upper and lower current or voltage limits. The clipped broadband signal (I c  (t)) is represented as a stationary Gaussian process to provide a reliable estimate of the carrier-to-nonlinear distortion per channel that would be experienced with a given laser or optical modulator. 
     The distortion control technique of the present invention is equally applicable for both directly and externally modulated lasers. In a directly modulated system, for example, an amplitude limiter (20) may be used to clip the multiplexed signal to prevent excursions below the threshold and/or above saturation and thereby avoid the unpredictable levels of nonlinear distortion associated therewith. Instead, the clipping levels can be set to achieve an acceptably low level of non-linear distortion.
