Patent EP-0394947-A2 (EP)
Inventor: KANAMARU TOSHIHISA C O SAIBU G
IPC: C10L3/10
Filed: 1990-04-24
Abstract: This invention relates to the improvement of the so-called PSA method, and more particularly to an apparatus for removing inert gases such as C0 2  gas, moisture and the like, and recovering active gases such as H 2 , CH 4  and the like as useful fuel gases for city gas with the utmost effciency, which are commonly produced during the intermediate process of city gas production on SNG basis in using the PSA method. The present inventive system comprises four adsorption column units (A)(B)(C)(D), each of which is used in sequence cyclically under the rotation including an adsorption process, a super-adsorption process with a rinsing step, a desorption process with a series of depressurization steps by suction, and a pressurization process by means of a carbon type adsorbent filled within the columns. The recovered gases obtained in the desorbed gases are recycled into a crude gas feeding pipe line (a), as these still contain a combustible component such as H 2 , CH 4  and the like which require further refinement repeatedly without any gas pressure fluctuation because of the employment of a water-sealed gas holder (12) positioned between a desorbed gas pipe line (g) and a recovered gas pipe line (f).

Abstract: A method for selectively removing a desired insulating film from a wafer surface. The method includes the steps of: preparing vapor containing hydrogen fluoride and water; keeping a temperature of the wafer surface higher than a temperature of the vapor by a prescribed range; and supplying the vapor to the wafer surface. Due to the difference in responsiveness caused by the temperature difference of the range, only the desired film, for example, the native silicon oxide film formed on the silicon layer surface is selectively etched and removed by the hydrogen fluoride. It is not necessary to extremely reduce the water content in the reaction system or to accurately regulate the concentration of the hydrogen fluoride gas.

Abstract: A data processor decoding and executing a train of instructions of variable length. The data processor includes a first instruction control means (1) for temporarily storing a prefetched instruction code (D1) and sequentially outputting said instruction code with units of a predetermined number of bits, and a second instruction control means (2) for decoding an instruction code (D2) fed from the first instruction control means, generating control information (D3) for data processing based on the decoding, and outputting data (D4) indicating instruction update demand quantity to the first instruction control means. On the basis of the data indicating the requested quantity of update instructions, the first instruction control means judges whether it has output a valid instruction code of length exceeding the update demand quantity, and provides an indication (V/INV) of validity or invalidity of the decoded instruction code and controls updating of the instruction code based on a result of the judgement. As a result, it becomes possible to reduce time necessary for the supply of instruction codes and thus improve a data processing speed as the entire processor.

Abstract: An ammunition unit (1) is provided with a fuze function which is sensitive to impact on both soft and hard targets (19) and comprises a front barrier (2) which effects piercing of a hard target. Mounted behind the barrier is a safety and armament part (6). This is fixed in its longitudinal displacement direction by means of a locking member (14). The locking member yields when the ammunition unit, after striking the target (which causes a certain compression of the ammunition unit in its longitudinal direction), undergoes rearward compression and thus causes a relative movement between the barrier of the part connected to it and the safety and armament part (6). A relative movement is permitted between the safety and armament part and the other parts of the shell, with simultaneous retention of the centring of the safety and armament part in the ammunition unit.

The package includes a plurality of reference marks (36, 38, 40, 42) and surfaces such that the laser (22), the lens (24) and the uptapered end of a single-mode optical fiber (30) may be positioned for precise optical coupling using an active alignment for final adjustments. The reference surfaces include a pedestal (16) for the laser (22) and a plurality of stops (18, 20) for the lens (24) integrally formed with the substrate (14). The package also includes a fiber tube (32) and flange (34) for mechanically positioning the uptapered fiber (30). The precisely calculated spacing based on the spacing of said photo-active element, the magnification of said lens, and the fiber positioning is achieved by mechanical means. A method of optically coupling the laser to the optical fiber includes securing a graded index lens to a substrate carrier within a housing at a distance calculated to provide a known magnification of a light beam emanating from said element, positioning and actively aligning the fiber to said magnified light beam to achieve optimal optical coupling to said optoelectronic device, and positioning the uptapered fiber securable to a flange.

Abstract: An implantable pacemaker provides a paced AV delay that is automatically adjusted to include patient variations in latency conduction, that is, the time interval between a stimulus to the heart and an evoked potential, time due to lead position and specific patient latency. An AV timer (50), designed to provide a programmed AV interval, starts its timing operation at the generation of an atrial pulse, and restarts the timing operation again at the occurrence of the evoked atrial potential. In this way, all variability in nodal conduction time due to lead position and specific patient latency is removed, thereby obviating the need of having the pacemaker make adjustments to the AV interval.

Abstract: 5 n7 A puffer switch has a cylindrical shell filled with an electrically insulating gas, such as sulphur hexafluoride. A plurality of spaced parallel plates cooperating with the shell for defining a separate compression chamber or volume for each phase of an electrical power circuit that is to be switched. Located in each volume is at least one set of contacts which are subject to arcing as the contacts open or close. A movable contact in each of the sets of contacts has an associated impeller blade which is mounted to rotate with the movable contact and to sweep through the volume for compressing insulating gas in front of the impeller blade. A nozzle associated with the impeller blade directs the compressed insulating gas onto the set of contacts at a point where the arc is possible. The switch is assembled in a low cost manner by supporting spaced parallel plates defining the volumes between them as a slip-in unit which fits into a shell. A thermosetting plastic is used for parts which become hot. A lower cost thermoplastic is used for most parts which do not become as hot.

Abstract: An indexing mechanism for use in a garment pressing machine includes a support frame (3), a guide rail (12) secured to the frame, a carriage (20) supported by the guide rail for linear movement between dressing and pressing positions, and a fluid actuator (52) for moving the carriage. The carriage carries a pressing buck or mannequin.

The actuator is connected between the support frame and a central portion of the indexing bar. Extension and retraction of the fluid cylinder causes the indexing bar to pivot and slide about one end within the guide and to drive the carriage between its dressing and pressing positions at its other end. The other end of the guide bar attached to the carriage moves a greater distance than the actuator extension motion due to the motion amplification effect of the indexing bar.
