Patent JP-3131242-B2 (JP)
IPC: G01B9/02
Filed: 1991-05-23
Granted: 2001-01-31
Abstract: The measurement of an angle of incidence ( alpha ) of a light beam (W) uses a polarised light beam which is passed through a birefringent plate (7) and then through an analysing polariser (9) to obtain a series of interference fringes. The spacing between the peaks of the said fringes, which is a direct function of the angle to be measured, is analysed using a suitable detector (10) and an electronic circuit (11). 
<??>A device of this sort can be used to measure the distance between itself and a reflecting surface on the object to be measured (12). A reference spacing between the peaks of the interference fringes is determined for a certain position of the object and the variation in the spacing is measured as a function of the various positions of the object. These positions are then displayed in units of length. 
<??>With such a method, angles of incidence or distances can be measured using a device which is compact, has a greater range of measurement than previously and is more accurate.

Abstract: An image display apparatus comprises a display panel formed by arranging in juxtaposition a face plate carrying thereon a phosphor and a rear plate carrying thereon electron-emitting devices within a housing. The phosphor is so arranged as to be irradiated with electrons emitted from the electron-emitting devices to display images. The image display apparatus further comprises an air blowing means for causing cooling air to flow between the display panel and the housing so that the cooling air first exchanges heat with either one of the rear plate or the face plate and then, after turning around, with the other plate. The air blowing means may be arranged at the centre of the housing, facing the rear plate. Alternatively, it may be arranged at a lateral proximity of the display panel. <IMAGE>
Patent JP-H0422075-B2 (JP)
IPC: H04N7/36
Filed: 1983-07-23
Abstract: A conditional replenishment video data transmission system involves the transmission of digital values representing the brightness changes at picture elements of a raster scanned image since the previous frame. Since nothing is transmitted for those picture elements without a significant brightness change, the amount of data to be transmitted will depend on the extent of movement in the image, and buffer stores are provided to allow the use of a constant transmission rate. If the extent of movement in the image is very high the buffer store at the receiver will tend to fill up and might overflow. In order to avoid this occurring, reduction of the amount of data to be transmitted by element subsampling has been proposed in which in a cluster of changing elements data relating to only some, for example alternate ones, of the elements are transmitted, and interpolation is used at the receiver to calculate the brightness change data for the omitted elements. The blurring of vertical edges in the image resulting from the interpolation is avoided by suspending sub-sampling where vertical edges are detected in the image. When in the sub-sampling mode, in order to avoid having to mark those normally omitted elements for which data are transmitted the receiver is arranged to detect the presence of a vertical edge and respond by treating the data as if they relate to all elements in the vicinity of the edge and not just the sub-sampled ones. Transmission error can result in the receiver being incorrect in the detection of edges, and to avoid this the number of quantizing levels during sub-sampling is reduced from 8 to 4, using one set of 4 codes for the normally present elements and the other set of 4 codes for the normally omitted elements. Since a vertical edge will usually appear in more than one line, the receiver may be arranged to check the previous line for a vertical edge and anticipate the inclusion of normally omitted elements if such an edge has occurred.

Abstract: For measurement of gas pressure a gas-friction vacuum meter is used in whose measuring head a rotating body is suspended in a magnetic field contact-free between electromagnetic drive coils. The rotating body is set in motion with the aid of the drive coils and maintained at a rotational speed above a preset minimum rotational speed. The speed reduction of the rotating body occurring on account of gas friction is continually or intermittently balanced with current flows from a three-phase generator to the drive coils. In the measuring head rotational speed sensors are arranged and positioned, which detect and respond to the rotational frequency of the rotating body, and further transmit output signals to an electronic analyzer unit, which determines the pressure from the timely change of the rotation frequency. In order to increase the pressure range for which the apparatus may be accurately used further, the analyzer unit receives a temperature signal, which correlates with the temperature of the gas surrounding the rotational body, in such a way, that the pressure measurement is corrected for the influence of heat transferred to the gas during operation of the rotating body.

Abstract: A host computer and printer and method of operation is disclosed wherein the data file describing a document is examined by a resource assembler which determines which resources are required from the host computer to print the document. The resource assembler translates the document into a set of render primitives for each band or page of the document and creates an dependency list interrelating the required resources with each band or page. The resource assembler places the required resources and set of primitives into a host resource store and communicates the dependencies to other portions of the system. A resource loader uses the list to determine the most efficient manner for loading and releasing resources from a printer resource store. A resource scheduler controls the actual timing of resource and primitives transfer and determines when all required resources for a band or page are present within the printer resource store. The resource scheduler generates an execute signal which causes a resource executor to convert the primitives to a bit-map data file. The resource assembler may convert the primitives to a bit-map data file if the resource executor cannot convert the primitives in real-time while the print engine is printing the band or page. The resource assembler also converts the primitives if it is more efficient than the resource executor for converting a particular band or page. If bidirectional communication is available between the printer and host computer, the printer manages its own memory and determines the most efficient printing sequence. Enhanced error recovery is also possible with bidirectional communication. <IMAGE>

Abstract: In a machine for making paper booklets from a multiplicity of paper strips on bobbins that are converged into a continuously advancing strand a reciprocating cutting station (25) defined by leading and trailing plates (27, 28) performs the operations of firstly clamping the strand while the station (25) moves with the strand and secondly of cutting off booklet lengths of paper by means of a knife (156). Cut booklets are ejected into a discharge chute (32) by ejection means (200) including an ejector bar (211) terminating a thrust plate (214). According to the invention the ejection means (200) is separated from the cutting station (25) and is fixedly located opposite to the chute (32). Connection between the cutting station (25) and the ejection means (200) is established by a common rotating hexagonal shaft (76) which is operably connected to clamping and cutting mechanisms of the station (25) and which carries a pair of cams (207, 208) that actuate the ejector (211) through a parallelogram linkage. By this means the motion of the ejector (211) can be gradual rather than abrupt, the machine is easier to set up, and the ejector thrust plate (214) can span substantially the full width of chute (32) so that the likelihood of cut booklets becoming misplaced is reduced.

Abstract: The present disclosure describes flame-retardant, high-temperature resistant polyimide fibers, nonwovens made from said fibers, as well as the fibers and molded articles obtained after a heat treatment. A composite of such fibers is heated to a temperature in the glass transition range of the fiber, i.e. between 280 DEG  and 350 DEG  C. This heat treatment develops a contraction force of 0.3 to 1.1 cN in the fibers which results in a fiber shrinkage of between 20 and 60% and the formation of cohesive bonds. The fibers of the invention enable the manufacture of molded articles that are particularly strong, have a high temperature resistance and flame-retardant properties, while having a relatively low density.
