Abstract: An objective changer for a telescope-type stereomicroscope which has two telescope systems whose entrance-side beam paths are oriented parallel to one another, which includes a carrier and an objective holder which is held at the carrier so as to be movable relative to the carrier between a first stereoscopic working position and a second stereoscopic working position and a third working position. The objective holder has at least a first and a second receptacle for stereo objectives and a third receptacle for an additional objective. The two telescope system beam paths penetrate one of the receptacles for the stereo objectives at least in the stereoscopic working positions when the objective changer is arranged at the stereomicroscope.

Abstract: A liquid drop ejecting head includes a cavity section which is formed by laminating a plurality of plates including at least first and second manifold plates adjacent to each other in a laminating direction. Each of the first and second manifold plates includes an opening. The openings overlap with each other when viewed in the laminating direction. At least one of the openings includes: a first opening which extends in the first direction and serves as a common liquid chamber; a second opening which is adjacent to the first opening and serves as a supply path; and a partitioning portion disposed between the first opening and the second opening.

Abstract: A signal processor 12 acquires a second signal obtained by detecting a first signal, as a signal of the real world, having a first dimension. The second signal is of a second dimension lower than the first dimension and has distortion relative to the first signal. The signal processor 12 performs signal processing which is based on the second signal to generate a third signal alleviated in distortion as compared to the second signal.

Abstract: Audio signals and video signals are recorded as follows. Three video PES packets, each being formed of one video frame, are combined to form a video editing unit. Then, the video editing unit and the associated audio editing unit are alternately disposed on a magnetic tape. The recorded PES packets are output as a TS as follows. A STC is initialized, and then, PSI packets of a PAT and a PMT are output. TS packets specially used for a PCR for storing the STC are then output at certain intervals. Subsequently, video PES packets are converted into TSs, and the output of the video TSs is started while synchronizing a time obtained by subtracting vbv_delay from the first I-picture DTS with the STC. Audio PES packets are converted into TSs, and the output of the audio TSs is started while synchronizing a time obtained by subtracting the start up delay from the first frame with the STC. Data streams are recorded in the following manner.

Abstract: An apparatus and method for producing a high contrast, real time, three dimensional representation of a scanned object with the use of an additional scanning mechanism to gain information about the third dimension. A light beam is reflected along an input path and is modified, split, scanned in a first direction, scanned in a second direction, and directed through a stereo base producer to provide stereoscopic information by impinging the beam onto the surface from two different directions. It is then reflected onto the surface whereby the light traverses an output path identical to the input path towards a splitter. Some of the reflected light is directed towards a photodetector coupled to a signal processor to produce an image for real time viewing.

Abstract: The use of compounds of the formula (I) R1aRebOc•Ld  (I), in which a=zero or an integer from 0 to 6 b=an integer from 1 to 4 c=an integer from 1 to 12 d=an integer from 0 to 4 L=Lewis base and the total of a, b and c is such as to comply with the penta- or hepta-valency of rhenium, with the proviso that c is not greater than 3•b, and in which R1 is absent, identical or different and is an aliphatic hydrocarbon radical having 1 to 10 carbon atoms, an aromatic hydrocarbon radical having 6 to 10 carbon atoms or an arylalkyl radical having 7 to 9 carbon atoms, where the R1 radicals can, where appropriate, be substituted identically or differently, independently of one another, as catalysts for the selective oxidation of olefins with cleavage of C═C bonds to give the corresponding carbonyl compounds in the presence of a peroxide-containing compound, where the amount of substance ratio of olefin to peroxide-containing compound is in a range from 1:

Abstract: A formatting apparatus authenticates an information signal prior to mass duplication of the signal by analyzing the signal to detect the presence or absence of a security signal therein, inserting a security signal into the information signal, and recording the modified signal only if no security signal was detected.

Abstract: Error-correcting apparatus and method for detecting and correcting a burst error affecting a plurality of reproduced signals representing adjacent data words groups the signals, calculates syndromes, determines the positions of errors in the reproduced signals and detects burst errors.

Abstract: A disc device for reproducing and outputting an information signal recorded on a disc-shaped recording medium is disclosed. This disc device reproduces, from the disc-shaped recording medium, an information signal which has been sequentially input, converted to a data structure having a specified format in specified block units and recorded on the medium, and generates a time code for the reproduced information signal based on reproduced information blocks and addresses of these blocks.
