Patent EP-0234669-A2 (EP)
Inventor: PATTON RICHARD A
IPC: C23C24/00
Filed: 1987-01-05
Abstract: A zirconium compound such as zirconium sulfate is added to a magnesium oxide separating coating composition. The composition is applied to decarburized regular silicon steel or high permeability silicon steel as a coating, then the steel is coiled and box annealed to orient its grain structure in the machine direction, thereby increasing its magnetic permeability. The coating isolates the coils of steel during annealing to prevent welding, and provides an electrically resistive glassy coating on the steel following the box annealing process. The presence of zirconium in the coating composition reduces the core loss of the processed steel, prevents oxidation of the steel during the process, and improves the chemical resistance of the steel to phosphate secondary coatings which are commonly applied after the box annealing step is complete.

Abstract: Silicon nitride sintered bodies of high strength at high temperature comprise not less than 70% by weight of Si₃N₄ and essentially consist of Si, O, N and a remainder being at least two of the rare earth elements Y, Er, Tm, Yb and Lu. The ratio of the molar amount of all the rare earth elements when calculated as Ln₂O₃ in which Ln is Y, Er, Tm, Yb or Lu to the molar amount of oxygen when calculated as SiO₂ is in a range from 0.4 to 1.3. The amount of oxygen when calculated as SiO₂ is obtained by subtracting the amount of oxygen in all the Ln₂O₃ from the amount of oxygen in the sintered body and expressing the remaining amount of oxygen as SiO₂ . Each of the rare earth elements is not more than 95 mol% of the sum of all the rare earth elements in the sintered body. The intergranular phase of the Si₃N₄ grains is substantially a crystalline phase of which not less than 50% is a crystalline phase of an apatite structure. Such bodies can be made by pressureless sintering or sintering in a pressurized atmosphere.

Abstract: Thin film electrical structures, such as threshold switching devices and phase change memory cells, preferably utilizing electrically stable, relatively inert, conductive electrodes including a non-single-crystal deposited film of carbon material, are disclosed. The film of carbon material, which preferably is amorphous and substantially pure, is disposed adjacent to a layer of active material such as an amorphous semiconductor, and serves to prevent undesired degradation of the active material, especially when the device is carrying appreciable current in its on-state. A method of making such structures with high quality interfaces between the semiconductor layer and the conductive carbon barrier layers adjacent thereto by successively depositing such layers in a continuously maintained partial vacuum is disclosed. The method may include a step performed in the vacuum for hermetically sealing all of, or at least the electrically switchable portion of, the active layer against subsequent contamination. Thin film structures suitable for threshold switching or memory applciations and employing insulating pores having substantially sloped side walls are also disclosed.

Abstract: Modern D.C.-tractioned trains and track circuit signal systems as well as high load trains need a special track construction. A new concrete cross sleeper system is provided for high load and high velocity tracks as well as for urban rapid transit systems comprising rails and sleepers having center part, connected to bar shaped ends and having reinforcing means. On the bar shaped ends two rail seats for each rail are positioned having elastic, electrically non-conducting plastic pads. The rails are fastened onto the rail seat by special tension means clamping the foot of the rail and fixed into plugs in the sleepers. This feature allows a triple point fixing of the rail at each sleeper end. Tracks on asphalt pavement may be secured by anchor device of the general type as sold under the trademark NELSON. The new track construction decreases the intermittent load of the rail/sleeper system and avoids trouble in track circuit signal systems existing in normally used prestressed concrete sleepers (FIG. 1).

Abstract: An apparatus which makes use of a preliminary transference stage prior to a main transference stage at the time of transference of a medium (1) such as a sheet of paper. In the former stage, an initial parameter setting operation is performed so and (1) that a desired amount of feeding of the medium control parameters for achieving this feed amount, including the amount of control rotation, rotational speed and are (15, 8) acceleration on starting of a transferring motor automatically determined on the basis of external factors used as parameters such as the number of operations of the transferring apparatus, the type of the medium and desired environmental factors of use of the apparatus including temperature and humidity. In the initial parameter setting operation, an unknown friction coefficient of the medium is determined. In the main transfererence stage, data thereby obtained enables the medium (1) to be transferred with constant accuracy no matter what the thickness, difference in level, friction coefficient of the medium (1), as well as environmental factors.

Abstract: Each time an actuator (11) is rotated in engagement with respective teeth (15) of a frame counter (17) in a disposable camera (1), the counter is rotated the equivalent of one frame to its next setting. To initialize the counter from a random setting during factory prewinding of an unexposed filmstrip (F) onto a take-up spool (3), the counter includes an elongate rise (39) located between two of its teeth (15). When the counter (17) is rotated sufficiently in a prewinding direction to locate the elongate rise (39) immediately ahead of the actuator (11), the counter (17) is initialized. Since the actuator (11) cannot surmount the elongate rise (39), continued rotation of the actuator in a prewinding direction will not rotate the counter (17) to another setting. Thus as the filmstrip (F) continues to be factory prewound onto the take-up spool (3) the counter (17) remains initialized.

Abstract: In magnetic recording and reproducing apparatus for recording and reproducing PAL and SECAM color video signals in both high and standard picture quality modes respectively, luminance signals are separated from AM carrier chrominance signals in PAL mode by a YC separating comb filter (2) and then supplied to first (4) and second (5) low-pass filters for preventing aliasing noise from being generated and when the luminance signals are thereafter frequency modulated in PAL color video signal recording mode, while luminance signals are separated from FM carrier chrominance signals in SECAM mode by the same second low-pass filter (5) before frequency-modulated in SECAM color video signal recording mode. Since the second low-pass filter (5) can be used to prevent aliasing noise in PAL video signals recording mode and further to separate luminance signals from the carrier chrominance signals in SECAM video signal recording mode, it is possible to reduce the number of low-pass filters.
