The packaged and sterilized mineral water can be effectively prepared by a method which comprises packaging pumped-up mineral water in a container without subjecting it to any heat-sterilization treatment wherein the mineral water is sterilized by passing through a filter having a pore size of not more than 0.22µ m, packaged in a sterilized container under an aseptic condition of not more than Class 100 and then the container is airtight-sealed. Thus, packaged and sterilized mineral water having excellent keeping quality can be obtained without subjecting pumped-up mineral water to any sterilization by heating and without using any antibacterial agent and it has a high hardness and a high carbon dioxide content as well as good taste peculiar to the original mineral water.

Inventor: SOLHEIM ALAN G
IPC: H01L29/73
Filed: 1991-03-28
Abstract: A high performance bipolar transistor and a method of fabrication. Base resistance is reduced by a self-aligned silicide formed in the single-crystal region of the extrinsic base, thereby eliminating the polysilicon to single-crystal contact resistance as well as shunting the resistance of the single-crystal extrinsic base region. Oxide from the sidewall of the polysilicon local interconnection is selectively removed prior to silicide formation. Therefore, selected sidewalls of the poly interconnect layer also becomes silicided. This results in significant reductions in resistance of the interconnection, particularly for sub-micron geometries. Improved techniques for forming field oxide regions and for forming base regions of bipolar transistors are also disclosed.

Abstract: A neural network circuit, in which a number n of weight coefficients (W1-wn) corresponding to a number n of inputs are provided, subtraction circuits determine the difference between inputs and the weight coefficients in each input terminal, the result thereof is inputted into absolute value circuits, all calculation results of the absolute value circuits corresponding to the inputs and the weight coefficients are inputted into an addition circuit and accumulated, and this accumulation result determines the output value. The threshold value circuit, which determines the final output value, has characteristics of a step function pattern, a polygonal line pattern, or a sigmoid function pattern, depending on the object. In the case in which a neural network circuit is realized by means of digital circuits, the absolute value circuits can comprise simply EX-OR logic (exclusive OR) gates. Furthermore, in the case in which the input terminals have two input paths and two weight coefficients corresponding to each input path, the neuron circuits form a recognition area having a flexible shape which is controlled by the weight coefficients. Neuron circuits are widely used in pattern recognition; neuron circuits react to a pattern inputted into the input layer and recognition is thereby conducted.

Abstract: This device comprises at least a wide conveyor (1), a conveying-direction sorting guide (2), a product-distributing means (5), a first gate (6), and a second gate (7). Said wide conveyor (1) has a front end that is connected to the end of the carrier conveyor (A), which carries products (a) in a single row, extends to the product-distributing and collecting area and has a sufficient width to carry a predetermined number of rows of products. Said conveying-direction sorting guide (2) has, near the upper surface of said wide conveyor (1), a front end for receiving products from said carrier conveyor (A) and a rear end for discharging said products, the rear end side thereof is capable of being oscillating. Said product-distributing means (5) has a mutually facing pair of vertical conveyors (3, 3) above the wide conveyor (1). Said front ends of the vertical conveyors (3, 3) are connected to the rear end of said guide (2) and convey the products by sandwiching them in the conveying direction at about the same speed as said wide conveyor (1), in such a manner that when said vertical conveyors (3, 3) discharge a predetermined number of products from the end row position, the discharging part sequentially moves to the row position adjacent to the current row position so as to move reciprocally between the rows at both ends. 
     After the products are temporarily stored in multiple rows in sets of a fixed amount at the first gate (6), the gate (6) opens and the second gate (7) distributes and collects the products in sets of a fixed amount into a predetermined number of rows.

Abstract: System for information exchange between a read/write unit (2) and an information carrier (4) which stores the information signals in a memory (38). The exchange of information is controlled by a microprocessor (6), while the data to be stored in the memory (38) are to be monitored.

With a logic "high" value on the basis of the transistor (32), tuned circuit (34, 36) is short-circuited and no longer resonates. The resonating or not of the tuned circuit is detected by a detector (14) and passed on to the processor (6).

Abstract: A computer network has a number of computers coupled thereto at distinct nodes. A trust realm table defines which computers are members of predefined trust realms. All the members of each predefined trust realm enforce a common set of security protocols for protecting the confidentiality of data. Each computer that is a member of a trust realm enforces a predefined security policy, and also defines a security level for each set of data stored in the computer. Thus, each message has an associated label denoting how to enforce the computer's security policy with respect to the message. A trust realm service program prepares a specified message for transmission to a specified other computer system. To do this it uses the trust realm table to verify that both the computer system and the specified computer system are members of at least one common trust realm, and then selects one of those common trust realms. The message is transmitted as a protocol data unit, which includes a sealed version of the message, authenticated identifiers for the sending system and user, the message's label, and an identifier for the selected trust realm. Received protocol data units are processed by validating each of the components of the received protocol data unit before accepting the sealed message in the protocol data unit as authentic. Further, the label in the received protocol data unit is used by the receiving computer to determine what predefined security policy is to be enforced with respect to the message.

Abstract: A motion image data compression coding apparatus and an image data compression coding method capable of smoothing compressed data among frames are disclosed. A data amount of compressed data is obtained by a hybrid coding of a combination of an orthogonal transform such as a discrete cosine transform, a quantization and a variable length coding of motion image data of one frame. A quantization step size is expressed by a product of a scaling factor f and quantization matrix factors q. The scaling factor f is determined from a code amount produced up to the preceding frame, a target code amount and an AC level of the transform factors of the present frame. Prior to the quantization and the variable length coding, a code amount actually resulted by the same coding is detected, and by considering the actual code amount, the scaling factor f for the last quantization is corrected.

Abstract: A measuring circuit which allows a capacitance to be measured in accordance with the discharge method is to be protected against external voltages without a component like a fusible link being destroyed and having to be exchanged in the case of a fault. As protection, a PTC resistor (RK) is used in connection with threshold elements (D1, D2) which short circuit dangerous voltages and limit the short-circuit current. Since the charging time constant is increased due to the PTC resistor (RK), the permissible capacitance measuring range is restricted to a maximum value. Transgression of the maximum value is signalled with the aid of monitoring means (3, 4) of a sequence control (4) which, in turn, ensures that there are no faulty indications and the transgression of the measuring range becomes recognisable. The measuring circuit can be used in measuring instruments for measuring capacitance and in multimeters. <IMAGE>
