Title: Sensor unit drive device and display device
Inventor: HOGO HIDEKAZU
IPC: G06F1/16
Filed: 2023-01-17
Abstract: To provide a sensor unit drive device with which it is possible to store a sensor unit while reducing the width of a bezel without causing the bezel to project forward from a display surface, and it is possible to move smoothly from the stored state to measure the display surface. According to the present invention, there is provided a sensor unit drive device comprising a sensor unit having a sensor and a drive means, the sensor unit being provided on a side surface of a display panel in a retracted position, configured such that a sensor faces a display surface in a detecting position, and configured so as to be able to switch between the retracted position and the detecting position by moving when a driving means drives the sensor unit, and the sensor unit being configured so as to move to the detecting position through a rotating action of turnably rotating from the retracted position about a rotation axis not perpendicular to the display surface, and a bending action of bending toward the display surface via a hinge structure.
Patent TW-202329088-A (TW)
Inventor: KEILER FLORIAN
IPC: G10L19/008
Filed: 2014-10-17
Abstract: Sound scenes in 3D can be synthesized or captured as a natural sound field. For decoding, a decode matrix is required that is specific for a given loudspeaker setup and is generated using the known loudspeaker positions. However, some source directions are attenuated for 2D loudspeaker setups like e.g. 5.1 surround. An improved method for decoding an encoded audio signal in soundfield format for L loudspeakers at known positions comprises steps of adding (10) a position of at least one virtual loudspeaker to the positions of the L loudspeakers, generating (11) a 3D decode matrix (D’), wherein the positions   of the L loudspeakers and the at least one virtual position   are used, downmixing (12) the 3D decode matrix (D’), and decoding (14) the encoded audio signal (i14) using the downscaled 3D decode matrix  . As a result, a plurality of decoded loudspeaker signals (q14) is obtained.

Title: Method for producing vaccine against viral hemorrhage disease of rabbits
Inventor: MIROSHNYK SVITLANA PETRIVNA
Filed: 2002-07-26
Abstract: The method for producing the vaccine against viral hemorrhage disease of the rabbits consists in adding chloroform to the to the virus-containing material prepared in the buffered saline solution. The mixture is then kept followed by extraction and separation. Then the product is inactivated and aluminum hydroxide is added. Upon separation the antibacterial agents are added. For assaying the vaccine the serial dilutions 1:2, 1:4, 1:8, and 1:16 are made in the buffered saline solution. Each dilution of the vaccine is then injected imtramuscularly at a dose of 0.5 ml to the rabbits weighting no less than 2.5 kg. Seven days later the vaccinated rabbits are challenged with the virulent material at a dose of 1000 LD50 per 50 ml. The animals are then left for 10 days. The titer of the vaccine is calculated taking into account the number of the animals being alive in each group. Finally, the vaccine is diluted in the buffered saline solution to obtain the optimal titer.

Abstract: The invention relates to a process for treating tantalum and/or niobium containing raw materials such as wastes, slags, concentrates and ores. The tantalum and/or niobium containing raw materials are processed by repeated use of a solution of ammonium fluoride. From the tantalum and niobium containing aqueous solution a mixture of fluorides and oxide fluorides of tantalum and niobium are transformed into a firm condition. At an extraction stage pure, aqueous solutions containing fluoro acid complexes of niobium and fluoroammonium complexes of tantalum are obtained. From these tantalum and niobium are obtained as oxides in pure form by precipitating them as fluoride containing oxide hydrates by addition of ammonia. The obtained oxide hydrates are transformed into pure oxides by calcining at high temperatures.

Abstract: 8679. Haddan, H. J., [Christian Fischer Eisengiesserei & Maschinenfabrik]. April 13. Sifting.-Relates to sifting - machines in n which hexagonal or like drums are employed. In the form shown in Fig. 4, the drum is suspended by rods, and is oscillated longitudinally by means of the crank g through intermediate rubber blocks o. The drum is also given a rotary movement by the action of an arm h carried by the bevel-wheel b upon the roller i carried by the drum. Each face of the drum consists of double steel plates, similarly perforated, of which the outer one is capable of a limited sliding movement. Each outer plate is supported by a rail u which moves longitudinally when the nose k comes in contact with the inclined surface l or m. The oblique guiding-slots c cause the openings in the plates to register more fully at this time than during the remainder of the revolution, so that grains &c. jammed in the slots fall back into the drum. When the drum is arranged to rotate without oscillating, the slots may be transverse instead of longitudinal, and an inclined surface causes a slight longitudinal movement of each outer plate once in each revolution.

Title: An Improved Method and Apparatus for Stemming Tobacco Leaves.
Inventor: BUTLER GEORGE PIERCE
Filed: 1898-07-16
Granted: 1899-01-28
Abstract: 15,580. Butler, G. P., and Butler, W. H. July 16. Tobacco.-Relates to a method of and machine for stemming tobacco leaves. The leaf is placed transversely across a set of feed or carrying bands 26 placed side by side, with spaces between in which the leaf-severing mechanism operates. The tip end d, Fig. 20, of the leaf is gripped between one of the bands 26 and a band 50, and during the time that the web of the leaf is severed transversely as at a, Figs. 20 and 22, the leaf is also gripped, nearer its butt end, between a second band 26 and a band 60. The web of the leaf is first cut by a series of puncturing-wheels 5, 6, 7, 8, 9, 10 operating successively, and each operating to puncture the leaf as the latter passes between the puncturing-disc and the corresponding pair of discs 70, 71, 72, 73, 74, 75 between which the puncturing-heads engage. The puncturing-discs consist of heads or points carried by flexible radial arms, so that the points can yield and so do not puncture or injure the stem or midrib. The leaf is also held by a series of clamping-jaws on an endless carrier C. After passing the puncturing- devices, the leaf is carried through an arrangement for severing the veins crossing the cut in the leaf. During this operation the stem of the leaf is tightened between the two gripping-devices, by means of a band 100 &c. which presses it into a groove in the carrying-band. The veins are engaged in and separated by the flexible arms of wheels 110, 111, 112 &c., and the veins are then pressed down on to revolving saws or cutters by means of notched discs. The latter are yieldingly mounted, and do not press the stem on to the cutters. The side portions b of the leaf are removed from the stem by diagonal rolls such as A, B covered with carding-cloth. The stem c, Fig. 22, is then cut off close to the tip by a disc cutter acting against a plain-edged disc. The carrying-belts, puncturing and severing devices, and stripping-devices &c. are driven by suitable arrangements of belts and toothed gearing &c.
