Patent EP-0431639-A1 (EP)
Inventor: ARPALAHTI OLLI
IPC: F23B90/00
Filed: 1990-12-07
Abstract: The invention relates to a method and apparatus for feeding solid material into a pressurized combustion or gasification plant in stages. The feed apparatus (l0) is provided with an inlet (l8), sluice chamber (30), and outlet (20). In a loading stage, solid material is conveyed through the inlet into the sluice chamber. The loaded sluice chamber is transferred to an unloading stage. During the transfer stage, the inlet (l8) is closed, whereas during the unloading stage, solid material is conveyed through the outlet (20) into a pressurized space (26). The volume of the sluice chamber (30) is adjustable so that the volume is enlarged during the loading stage and reduced during the unloading stage. The volume is adjusted, for example, by a piston (38).

Abstract: A resin layer (110) having flexibility and on the surface of which an uneven pattern (111) corresponding to information to be recorded is formed, and a reflection layer (120) formed on the uneven pattern of the resin layer and having light reflectivity are provided to thereby constitute a flexible optical information recording medium. Further, the resin layer is supported by a supporting layer (210) having flexibility. For manufacturing such a flexible optical information recording medium, a resin liquid (321), which can be hardened by irradiation of ultraviolet rays or electron rays, is filled between an ultraviolet ray or electron ray transmissible base film (301) serving as the supporting layer and an uneven pattern original block (304). Then, ultraviolet rays or electron rays (306) are irradiated through the base film to harden and give form to the resin liquid on the base film, thereafter to exfoliate it. For another manufacturing method, a resin layer (401b) of a resin, which can be hardened by irradiation of ultraviolet rays or electron rays and has thermal moldability, is formed on an ultraviolet ray or electron ray transmissible base film (401a) to form a rolled transfer film (401). The resin layer surface of the transfer film is pressure-welded onto the surface on which the uneven pattern is formed of the original block while softening the resin layer by heating it so as to transfer the uneven pattern. Then ultraviolet rays or electron rays (406) are irradiated through the base film to harden the resin layer which once has been softened, thus to exfoliate the transfer film from the original block. For reproducing such a flexible optical information recording medium (200), a flat plate like adapter is used. Reproduction of this recording medium with it being held by a lower surface adapter (511) and an upper surface adapter (512) is effective. When the thickness including the adapter is 1.2 to 1.5 mm, reproduction can be conducted using reproducing equipment on the market. Adhering adapter to the flexible optical information recording medium is equivalent to the conventional thick optical information recording medium. A flexible optical information recording medium according to this invention is particularly suitable for massproduction.

Abstract: Tracking control signals are produced in response to the scanning of data tracks on a record medium (11), with at least alternate ones of those tracks containing tracking information signals recorded in predetermined areas. The tracks are scanned by a transducer arrangement comprising first and second heads (HL, HT) offset from each other in a direction substantially transverse of the tracks and displaced from each other in a direction substantially parallel to those tracks, such that the first and second heads (HL, HT) scan two tracks concurrently over the major portion of a scanning trace of each head (HL, HT). Tracking information signals picked up by the first and second heads (HL, HT) during a scanning trace are detected; and a tracking control signal indicative of a tracking error relative to the tracks being scanned is produced in response to the tracking information signals picked up by the two heads (HL, HT).

Abstract: A bolt (10) is provided with a screw-threaded shank portion (16) which is adapted to receive a complementarily threaded nut (12) thereon. In use, the shank is passed through an aperture (18) in an object (20) to be secured and the nut threaded on the shank. As the nut is tightened, a projection (32) on the undersurface (26) of the nut engages with the surface of the object (20) and causes a slight pivoting of the nut. This results in misalignment of the threads of the shank (16) and of the nut (12) and causes a frictional locking between the two. 
     In other embodiments, the projection is provided on the head of the bolt and on a washer interposed between the nut (12) and the object (20) or the bolt head (14) and the object (20).

Abstract: A system of using a metallic conveyor belt (10) in the manufac­ture of can lids which prevents can lids (11) from rotating as they are conveyed from one manufacturing station to another. Thus, the lids (11) are not improperly case and stamped, which would result in having to be discarded. A frictional augmentation area (13) of specific depth, width, and roughness is formed upon the metallic conveyor belt top surface to prevent the can lid (11) from rotating during manufacture. Thus, the present invention provides a simple and economically beneficial improvement to the manufacturing process of can lids (11).

Abstract: A vertical isolated-collector PNP transistor structure (58) comprises a P+ region (45), a N region (44) and a P- well region (46) forming respectively the emitter, the base and the collector of said PNP transistor structure. The P- well region is enclosed in a N type pocket comprised of a N+ buried layer (48) and a N reach-through region (47) in contact therewith. The contact regions (46-1, 47-1) to the P- well region (46) and to the N reach-through region (47) are shorted to define a common collector contact (59). In addition, the thickness W of the P- well region (46) is so minimized to allow transistor action of the parasitic NPN transistor formed by N PNP base region (44), P- well region (46) and the N+ buried layer, (48) respectively as the collector, the base and the emitter of said PNP transistor. The beneficial effects that result from paralleling this NPN parasitic transistor with said PNP transistor to form a PNPN or thyristor structure are superior to the inconveniences caused by the increase of the collector resistance of the P- well region.The said PNP transistor structure (67) can be advantageously combined with a conventional NPN transistor structure (61) in particular in BICMOS circuits wherein the output stage consists of top PNP/bottom NPN complementary bipolar transistors.

Abstract: The bottle (10) has two essentially identical indentations (20) on essentially opposite sides for gripping and manipulating the bottle. The indentation are designed to provide for the same gripping feel whether gripped front or the back. The indentations are also designed to accept a thumb and one to four fingers. The positive gripping with the same grip feel allows the bottle to be used in either hand. This decreases the number of times that a bottle must be handled during use. It also decreases the likelihood that the bottle will be dropped while being handled.
