Abstract: A printer is capable of stably feeding even a thin recording medium to a printing section and obtaining good print quality similar to that obtainable in the case of a thick recording medium. The printer comprises a first supply path for supplying a first recording medium, a second supply path for supplying a second recording medium thicker than the first recording medium, a printing section for printing on a recording medium supplied from the first supply path or the second supply path, and a delivery section for delivering the recording medium printed in the printing section. A guide spring member which is movable up and down is projected upstream of the printing section and in a meeting portion of the first supply path and the second supply path. This guide spring member serves to support a top surface of the first recording medium at a predetermined height. <IMAGE>

Abstract: PROBLEM TO BE SOLVED: To facilitate the manufacture of uniform semiconductor manufacturing bonding tape by a method wherein the title semiconductor manufacturing tape contains a tape member transferably holding a bonding agent on one junction surface of a semiconductor chip or sheetlike member so that the thermosetting liquid bonding agent in semiset state may be held by the tape member. SOLUTION: The tape member 17 having thermal resistance and flexibility is to properly select e.g. a Teflon synthetic resin material easily releasable from a bonding agent in semiset state. In order to coat the tape member 17 with this bonding agent, a mask 21 is arranged above a screen printing base 19. On the other hand, a syringe 23 for periodically feeding a specific amount of liquid thermosetting bonding agent 24 is arranged on a mask 21. By the operation of this syringe 23, the bonding agent 24 fed on the mask 21 is spread on the mask 21 to be swept successively out of through holes 22 on the lower tape member 17. Through these procedures, the bonding agent 24 can be coated on the tape member 17 at a specific interval.

Abstract: PROBLEM TO BE SOLVED: To improve the luminance of a liquid crystal display device using the MVA system by forming projections which regulate the tilt direction of liquid crystal molecules at the time when driving voltage is impressed and making the perpendicular alignment regulating power of alignment layers in regions with the formed projections lower than that in regions with no projections. SOLUTION: Projections 28 comprising a transparent material are zigzag formed on an insulating film 24 and a pixel electrode 26 on a substrate 10. Projections 50 comprising a transparent material are zigzag formed on a common electrode 48 at a half-pitch interval between the projections 28 and 50. The perpendicular alignment regulating power of alignment layers 30, 52 in regions with the formed projections 28, 50 is made lower than that in other regions with no projections. Even liquid crystal molecules on the tops of the projections 28, 50 tilt when voltage is impressed and light transmits even on the projections 28, 50. The opening ratio of pixel parts is therefore increased.

Abstract: An automated interrupt driven system which employs a circular buffer is used to sort materials based on differing electromagnetic radiation absorption and penetration characteristics. The system has a conveyor and a source of electromagnetic radiation which radiates materials travelling along the conveyor. A controller samples detector outputs at various times to evaluate the absorption and penetration characteristics of the materials to be sorted, based on a plurality of samples. Portions of the materials are ignored to obtain accurate readings from the detectors. Based on the detected penetration and absorption characteristics, the controller activates ejection mechanisms causing materials of different compositions to be deposited into different bins. The controller executes interrupts to cause detection, ejection, testing, and system history maintenance at required times. The circular buffer contains indices which point to various locations which are programmed in memory to trigger and perform specific events. The location of the indices in the circular buffer is used to control event timing, such as activating and deactivating the ejection mechanisms. This configuration allows several events to be executed simultaneously by moving to the next location in the circular buffer while the event indicated by the index in the previous location continues in progress.

Abstract: 2.1 The invention has the object of increasing the loading, with the material to be comminuted, of the gas or steam jets used for milling in a fluidised bed consisting of granular material, in order thus to obtain a better utilisation of the energy of the jets. 2.2 This is achieved in that, when the jet emerges from a nozzle, in the peripheral region of the nozzle cross-section, the size of the jet impulse changes at least twice between a minimum and a maximum value and, in the core region of the nozzle cross-section, it is equal to or smaller than the minimum values of the peripheral region.   2.3 In the regions having a low jet impulse directly after emergence of the jet from the nozzle, a negative pressure gradient forms, in this arrangement, from the environment to the core region of the jet, so that flow channels result transversely to the flow direction of the jet, through which flow channels the particles of ground material are sucked in as far as the centre of the jet and are accelerated here, in the further course of the jet, to the impact speed necessary for their comminution. <IMAGE>

Abstract: In order to determine at least one parameter of interest in a living organism, a perfusion is directly introduced in the tissues. After its partial balancing by the tissue parameter of interest, the perfusion fluid is collected and analyzed for the parameter of interest, as well as for endogenous or exogenous marker properties indicative of the degree of interaction between the perfusion fluid and the tissue, in such a way that the parameters of interest can be determined with the help of such characteristic properties. Contrary to usual processes, used exclusively inside blood vessels or other body cavities filled with liquid, this process creates in the tissues, i.e. in the closed cellular structure, a previously inexistent cavity, in which the perfusion fluid introduced in the tissue interacts directly with the organic tissue, with no intervening membranes. The transfer of the measurement site into the tissue completely eliminates the risk of the thromboses and embolies, besides strongly reducing the risk of infection.

Date Feb. 15, 1996An ionizing radiation detector comprises a flat substrate having a plurality of etched parallel ridges on one surface. The parallel sides of the ridges carry a thin layer of a conducting material, acting as an electrode. A particle or radiation beam to be detected impinges on the ridges, in a direction normal to the plane of the substrate, so causing electron/hole carriers production within the ridges. The carriers migrate to the electrodes, in a direction perpendicular to the beam, thereby inducing charge on the electrodes. The readout can be extremely rapid, since the carriers need to migrate only a very small distance to the side of the ridge.
