Title: Content distribution system, content distribution device, content playback terminal, and content distribution method
Inventor: TAKAHASHI MAKI
IPC: H04N21/6408
Filed: 2010-12-13
Abstract: In a content distribution system in which a content distribution device distributes video content to a content playback terminal, the content distribution device multicasts video content added with cash control information to the content playback terminal and other content playback devices, before a user plays back video content selected from a distribution menu. The distribution playback terminal writes the video content in a temporal storage unit included in the distribution playback terminal. If the video content selected by the user is stored in the temporal storage unit, the video content is played back. On the other hand, if the video content selected is not stored in the temporal storage unit, a distribution request for the video content selected is made to the content distribution device.

Title: Video encoding control method and apparatus
Inventor: SHIMIZU ATSUSHI
IPC: H04N7/26
Filed: 2011-04-20
Abstract: A video encoding control method for controlling encoding of an input video signal. The method includes the steps of detecting an underflow of a decoder buffer; if the underflow of the decoder buffer has been detected, suppressing an amount of generated code by skipping an encoding target picture or by encoding the encoding target picture so as to produce a minimum amount of generated code; after suppressing the amount of generated code, comparing a current rate of occupancy in the decoder buffer with a predetermined threshold for the rate of occupancy in the decoder buffer; and performing a control for continuously suppressing the amount of code generated for each encoding target image by using the above step of suppressing the amount of generated code until the rate of occupancy in the decoder buffer exceeds the threshold based on a result of the above comparison.

Title: Process for removing fouling deposits from dielectric surface of electrostatic charge target electrode
IPC: B08B1/04
Filed: 1989-05-15
Abstract: A process for removing from dielectric surface (16) of electrostatic target electrode fouling deposits (50) generated substantially as tiny solidified polymer particles during flash-spinning of fibrous web structures. The particles are attracted to and deposited on the dielectric surface (16) of the target electrode (14) used for corona charging of the fibrous web structure and the resulting fouling deposit (50) increases the rate of loss in charging efficiency of fibrous structures. The process comprises brushing off fouling deposits by a self-cleaning rotating brush arrangement (45) to prevent build up of the deposits (50) on the surface (16) of the electrostatic target electrode (14) and to thusly significantly increase charging efficiency and lifetime of target electrode dielectric surfaces.

Title: Multicylinder self-starting uniflow engine.
Inventor: JOHNSTON BARRY
IPC: F01L25/04
Filed: 1990-01-04
Abstract: A uniflow engine has a plurality of cylindres (24) disposed symmetrically around a common crankshaft (26) connected to pistons (20) reciprocating in the cylindres. In response to the availability of a working fluid vapor at a predetermined condition, such as a high pressure or temperature, incoming vapor is supplied to those cylindres (24) in which the respective pistons (30) are in their working strokes to thereby initiate rotation of the crankshaft (26) in which the crankshaft (26) had stopped last. Once rotation is initiated and a predetermined mode change speed attained in a ''start-up mode'' by engine operation from start, vapor inlet valves (88) are controlled to change engine operation over to a ''running mode''. In the ''start-up mode'' incoming vapor is admitted over a substantial portion of the piston working stroke, whereas in the ''running mode'' vapor inflow is terminated relatively early in the working stroke so that a vapor change does work in expending against the piston.

Title: Oriented grained y-ba-cu-o superconductors having high critical currents and method for producing same
IPC: C04B35/653
Filed: 1990-02-08
Abstract: A superconductor material having a current density, J, of from about 30,000 to about 85,000 amps/cm2 at zero magnetic field and 77 DEG  K. is disclosed. The 123 superconductor is of the formula L1Ba2Cu3O6+ delta  wherein L is preferably yttrium. The process comprises compacting the solid state reaction product of L1Ba2Cu3O and then sintering the reaction product at a temperature between about 40 DEG C. to about 90 DEG  C. below its melting point, i.e., for Y1Ba2Cu3O6+ delta  at a temperature of approximately 940 DEG  C. The composition is then heated in a preheated chamber maintained at approximately 1090 DEG  C. to about 1,200 DEG  C. (approximately 1,100 DEG  C. for Y1Ba2Cu3O6+ delta ) until it has been decomposed, and is then rapidly cooled to a temperature between about 10 DEG  C. to about 30 DEG  C. above its melting point, i.e. for Y1Ba2Cu3O6+ delta  a temperature of 1030 DEG  C. and then is control cooled at a rate of 1 DEG  C./hr until it reaches a temperature of about 20 DEG  C. to about 40 DEG C. below its melting point, i.e., for Y1Ba2Cu3O6+ delta  a temperature of 980 DEG  C. The composition is steadily held at this temperature for at least eight hours, and then cooled to a temperature of approximately 400 DEG  C. below its melting point (for Y1Ba2Cu3O6+ delta  approximately a temperature of 600 DEG  C.). The material is then slowly cooled by another 200 DEG  C. and is then annealed in oxygen.

Title: Electrical control system for electrostatic precipitator
IPC: B03C3/68
Filed: 1990-06-29
Abstract: Form factor measurement and fault detection equipment to determine proper sizing of electrical components and efficiency of an electrostatic precipitator (22) by calculating a system form factor from either primary voltage or current. A power source (10) connects serially to an inverse parallel SCR 1 and SCR 2, to a current limiting reactor (16), and to a T/R set comprising a transformer (18) and rectifier (20) which supply power to precipitator (22). A current transformer (26) senses input current between the reactor (16) and T/R set (18, 20) to signal an input scaling and signal conditioner (28) connected to a current meter (34), a voltage meter (39) and a computer (40) having a display monitor (42). The computer (40) is also connected to an SCR control circuit (24) of SCR 1 and SCR 2. The appropriate electrical characteristic is converted to both its RMS value and average value and then sent to the computer (40). The computer (40) divides the RMS value by the average value and sends the resulting form factor value to the display (42). If system form factor value is not sufficiently close to the purely resistive circuit value of 1.11, then equipment resizing is needed to increase system efficiency. Additionally, secondary electrical characteristics are used to calculate fractional conduction. If the fractional conduction is not sufficiently close to a desired level, equipment adjustments are made to increase system efficiency.

Title: In-line detector system for real-time determination of impurity concentration in a flowing gas stream.
Inventor: TOM GLENN M
IPC: G01N33/00
Filed: 1991-12-13
Abstract: An in-line detector system for real-time detection of impurity concentration in a flowing gas stream in which purified and unpurified volumes of gas from the flowing gas stream are subjected to concentration sensing, to determine a corrected impurity concentration value for the flowing gas stream. The system in a preferred embodiment employs a manifold in flow communication with a purifier unit, a main flow conduit through which the flowing gas stream is passed, and a sensor port, with a selectively positionable valve to flow gas through a purifier loop of the manifold to the sensing port, and alternately through a bypass loop of the manifold without passage through the purifier unit, for comparative impurity sensing of gas in the respective loops. The system may utilize hygrometric sensors in the case of water as a critical impurity, or surface acoustical wave (SAW) devices coated with suitable impurity-affinity coatings. The system has particular utility in monitoring low impurity concentration levels (e.g., from about 0.1 ppm to about 100 ppm) in gas streams employed in vapor-phase processes such as chemical vapor deposition in the manufacture of semiconductor devices. <IMAGE>

Title: Palladium partial combustion catalysts and a process for using them
IPC: B01J23/44
Filed: 1991-11-26
Abstract: This invention is a catalyst comprising palladium on a support (102) and a partial combustion process in which the fuel is partially combusted using that catalyst. The palladium catalyst (106) may also comprise palladium mixed with metals selected from Group VIII or IB, may be graded (Fig. 1b) such as to have higher activity in the forward edge (112) of the catalyst, or may be placed on a support comprising zirconia. The choice of catalysts (106) and supports (102, 110) specified each solves a variety of problems dealing with the long term stability of the palladium as a partial combustion catalyst. The catalyst structure is stable in operation, has a comparatively low operating temperature, has a low temperature at which oxidation begins, and yet is not susceptible to temperature "runaway". The combustion gas produced by the catalytic process typically is at a temperature below the autocombustive temperature and may be used at that temperature or it may be fed to other combustion stages for further use in a gas turbine, furnace, boiler, or the like.
