Abstract: An apparatus and method for determining the individual mass flow rates of a multi-component flow. Individual components of the multi-component flow have different products of longitudinal relaxation time and flow velocity. Two or more arrangements of magnets and flow sensors are arranged along a pipeline. A static magnetic field is imposed on the flow. The linear movement of the flow then generates a multi-exponential gain of magnetization. By interrogating the flow at several positions, the magnetization and velocity is measured simultaneously in different positions. The multi-exponential gain of magnetization and determination of the equilibrium magnetization of each component thermal equilibrium can then be determined. The mass flow rates in the individual components can then be determined.

Abstract: The invention relates to a process for the preparation of a porous material layer covered with an electronically conductive polymer and to the product obtained by this process.This process consists of placing the layer (1) on a support sheet (3) optionally having roughnesses or unevennesses (4), applying to the layer a polymerization solution comprising a monomer (pyrrole), an oxidizing agent (FeCl.sub.3) and a doping agent (naphthalene disulphonic acid salt) using nozzles (6).

Abstract: A multilayer ceramic part including dielectric ceramic layers and internal conductor layers is prepared by forming dielectric ceramic layers from an oxide system dielectric ceramic material having a sintering completion temperature between the melting point and the boiling point of the internal conductor. A pattern of internal conductor is formed on dielectric ceramic layers. The dielectric ceramic layers are placed one on another so as to sandwich the internal conductor pattern therebetween. The laminate is fired at or above the melting point of the internal conductor, optionally in an atmosphere having a controlled oxygen partial pressure. Since the dielectric ceramic material has an improved dielectric constant and dielectric loss and the internal conductor is densified and improved in surface property, the part is improved in resonator Q value and other properties.

Abstract: In order to improve ability for driving the potential of a read bit line (192) to a high level, an output terminal (201b) of a memory circuit (21) and a read word line (182) are connected input terminals (204, 205) of a NAND gate (15) respectively. A gate of a transistor (123) is connected to an output terminal (203) of the NAND gate (15) and its source is connected to a power supply line (111) to be supplied with a VDD potential, while its drain is connected to the read bit line (192). MOS transistors (133, 134) are connected in series between the bit line (192) and a grounding conductor (112). Gates of the transistors (133, 134) are connected to the output terminal (203) and the input terminal (205) of the NAND gate (15) respectively. Thus, a time for converting the output terminal from a low level to a high level is reduced, whereby an access time can be reduced. Other embodiments of the above-described invention include different logic technologies used to construct the memory circuit (172).

Abstract: There are disclosed a styrenic resin laminate comprising at least one surface layer consisting essentially of a styrenic polymer having a high degree of syndiotactic configuration (SPS layer) and a foam layer (other layer) consisting essentially of a styrenic resin (GPPS, IPS, HIPS, ABS resin, SMA copolymer, AS resin, modified PPO; blend of HIPS/PPO, etc); and a molding obtained by thermoforming the above-mentioned laminate. The above laminate is particularly excellent in heat resistance and easily thermoformable into the molding, which is also excellent in heat resistance and recyclability in terms of retention of flexural strength, utilizable in heating oil-base food with a microwave range and can easily be recovered for reuse, thereby greatly contributing to environmental preservation and resources saving.

Abstract: A method and system in which a user manually changes the quality of specific time periods of encoded video. After the automatic encoding of video into a compressed digital format, a person editing the encoded video reviews the quality of the video and manually indicates that the quality of specific time periods of the video is to be altered. As the digital storage medium such as an optical disc which stores the encoded video has a finite storage capacity, the total number of bits for the encoded video and the quality of the video is limited. Consequently, in order to increase the quality for one time period, bits must be taken from other time periods. After the editor assigns the qualities to different time periods, a percentage of bits is removed from the time sequences and placed into a bit pool. The new number of bits for the various time periods are calculated using an exponential function and the bits in the bit pool are proportionally distributed to the video frames.

Abstract: A computer receives animated images together with a real world image. The computer then superimposes the animated images onto the real world image. The result is a combined animated/real image which forms the virtual world. The combined image is capable of moving as the user's head moves. Thus, complicated virtual worlds may be created without the programming complexity which would result if the entire image were animated.

Abstract: Polluted groundwater is purified by separating off solids and adsorbing dissolved organic compounds to an adsorber resin. The adsorbed organic compounds are desorbed using steam and the adsorber resin is regenerated using an acid and an oxygen-containing gas. The process makes it possible to separate aromatic and halogenated hydrocarbons off of heavily polluted groundwater to the extent that the groundwater can be added to flowing surface water without reservation. The purified water can, if appropriate, be used as cooling water, or after further biological purification, as drinking water.

Abstract: Disclosed is an improved system for the delivery of entertainment and educational programming from a plurality of electronic libraries to a plurality of users. Users actuate a hand operated control device to: review a listing of available programming; enable the delivery of a program from a library; or control the delivery of forwarding and rewinding through the programming, and authorizing the purchase of advertised consumer goods by entering in personal identification numbers. The network of libraries and the paths for delivering the programming stored therein is arranged for optimum transmission efficiency and maximum access capacity. The key idea in optimizing transmission efficiency and access capacity is to recognize that programming can be grouped into different classes, and that not all classes of programs should be stored in all libraries.
