Abstract: The composition consists of a two-part gelatin capsule in which there is a substance which increases in volume on release in the stomach, is non-toxic and has a low calorific value, and which can be broken down again within the digestive tract of the human body, for example compressed cellulose. This confers a feeling of repletion on the person taking it, owing to the enlargement in volume in the stomach, for a certain time, which facilitates weight reduction.

Abstract: A mass spectrometer includes an ion source (208) for ionizing a sample substance to provide an ion current of predetermined beam width and energy. A mass filter includes a plurality of drift tubes wherein succeeding drift tubes are of increasing length separated by gaps that increase in length. The ion current is supplied to the mass filter along with an alternating current electrical signal in a manner so that particles having a predetermined mass receive a predetermined maximum energy increase while traversing the mass filter and so that particles not having the predetermined mass do not receive the maximum energy increase. A detector (216) is provided to create an energy barrier whereby only particles that receive the maximum energy increase will have sufficient to completely traverse the barrier. Particles which traverse the barrier are detected thereby to determine the amount of particles having a predetermined mass that were contained in the sample substance.

Abstract: A phase shifting mask comprises a transparent region (20) which is transparent to exposure light and a light shielding region (10) for shielding the exposure light. The transparent region (20) has a light transmitting segment (12) for directly transmitting the exposure light therethrough and a phase shifting segment (11; 11a, 11b) for transmitting the exposure light therethrough with a phase difference from the light passed through the transmitting segment (12). In this structure, the light shielding region (10) is formed adjacent at least the phase shifting segment (11; 11a 11b) or the light transmitting segment (12), and the phase shifting segment and the light transmitting segment are formed adjacent each other. 
     A method of manufacturing such a phase shifting mask comprises the steps of: forming a light shielding layer on a substrate; forming a photoresist on the light shielding layer; patterning the photoresist to form a resist pattern; providing an opening in the light shielding layer by the use of the resist pattern as a mask, thereby forming a light shielding pattern; etching the substrate anisotropically to form a phase shifting segment (11; 11a, 11b); side etching the light shielding pattern to form a light shielding region (10); and removing the resist pattern.

Abstract: The present invention relates to a method of testing of digital and analog circuits. If a fault is detected, after stimuli are applied and test measurements are made at some circuit nodes, steps are taken to locate faulty circuit components. At least one further node is selected for measurement on the basis of the levels of information that such nodes can provide. Further measurements aid fault location. 
     For analog circuits, levels of information are determined by calculation of discrimination factors which depend on possible voltage ranges at unmeasured circuit nodes if various components are considered as faulty. The information gained from measurement at a further node is used to reduce the voltage ranges in order to aid selection of another node to measure.

Abstract: A knowledge base management system for a rule-based expert system. 
Reasoning predicates are generated from the raw primary data and stored in a secondary data storage (105) together with reasoning rules (106) to form the knowledge base (107). 
     It may be necessary to make changes to the format or nature of the primary input which may necessitate regeneration of parts of the secondary data. 
     Details of these changes are stored in the change registration section (103). The knowledge management section monitors access by the reasoning calculation section (108) to the knowledge base section (107). If an attempt is made to access secondary data affected by changes to the primary data, then that secondary data is re-generated by conversion section (104). Advantage dynamics updating of secondary data removes the need for time-consuming large-scale data regeneration.

Abstract: In a method for driving an active matrix type liquid crystal display device having a liquid crystal panel having the structure that a set of liquid crystal layers and two-terminal active layers are connected in series between a set of column electrodes and a set of row electrodes, a display operation being carried out by applying a difference signal between each column electrode and each row electrode, the difference signal is set so as to have a voltage having an inverse characteristic to the I-V characteristic of the two-terminal active element and is applied between the column and row electrodes to thereby depress occurrence of flicker. In addition, within a period except for a selection period for which an actual display operation is carried out in the liquid crystal panel, the difference signal having amplitude voltage equal to or above the maximum amplitude voltage set for the display operation is applied between the column and row electrode sets for a predetermined period to thereby prevent degradation of display quality due to the shift characteristic of the two-terminal active element which has been driven, and due to the asymmetry of the voltage-current characteristic of the two-terminal active element between the positive and negative polarity regions thereof.

Abstract: This invention is a highly efficient star coupler for use with single mode waveguides. In the inventive coupler, all of the input waveguides and all of the output waveguides are assembled to form two separate bundles. The two bundles are axially aligned with each other and the ends of the bundles are spaced apart. The ends of the waveguides of the bundle of output waveguides are polished to receive optical energy from the bundle of input waveguides. The end facet of the input waveguide bundle is shaped and polished to form a convex spherical surface. The diameter of each waveguide of the bundle is small relative to the diameter of the bundle of waveguides. Therefore, the end facet of each waveguide which makes up the convex spherical surface is angled very slightly relative to the waveguide axis. This slight angle on the end facet of the waveguide acts as a bevel to bend the optical energy coming out of the end of the waveguide. The shape of the end facets of the input waveguides and the spacing between the ends of the input and output waveguides are selected to enable the optical energy from each input waveguide to shine on all of the end facets of the output waveguides with substantially no spill-over of optical energy. To increase the efficiency of the device, the packing density of a bundle of waveguides can be improved by decreasing the size of the cladding of the waveguides and/or increasing the diameter of the core with an adiabatic taper.

Abstract: There is disclosed a process for continuously producing a highly syndiotactic styrenic polymer by using a horizontal self-cleaning type reactor which comprises feeding into the reactor, a catalyst or both the catalyst and a styrenic monomer dividedly into at least two portions, preferably 2 to 5 portions in the direction of the axis of the reactor. The above process facilitates the control for the reactor inside temperatures because of the stepwise feeding of the catalyst (and the styrenic monomer) and remarkably enhances the productivity by simply increasing the food rates of the catalyst and the styrenic monomer, thus making itself industrially highly valuable.
