Abstract: A reservoir (1) in which fuel can be collected when only a small amount of fuel remains in the fuel tank (203), is arranged to support a fuel pump (75) and to be connectable to the lower wall (205) of the tank by a snap action type connector arrangement which is defined between a bracket (41) fixed to the lower wall of the fuel tank and a portion of the reservoir which cooperates with the bracket. The reservoir containing the pump can be manually introduced into the interior of the fuel tank through a opening (203a) in the top thereof and maneuvered into engagement with the bracket. The center of gravity of the relatively heavy pump is arranged to be generally over the top of the bracket. When a predetermined strong force is applied the reservoir in a predetermined manner it can disengage from the bracket.

Abstract: A tool member includes a tungsten-carbide-based cemented-carbide substrate and a diamond coating deposited on the substrate. The substrate has two diffraction peaks Kα₁ and Kα₂ indexed by index of plane (211) for tungsten carbide in X-ray diffraction. The peaks satisfy the relationship of l₁/l₂ ≦ 35, where l₁ and l₂ are heights of the peaks Kα₁ and Kα₂ measured from a base of a trough between the two diffraction peaks. For manufacturing the tool member, a green compact is first sintered to provide a tungsten-carbide-based cemented-carbide substrate. Subsequently the substrate is ground and subsequently heat-­treated at a temperature between 1000 °C and 1600 °C in a vacuum or in a non-oxdizing atmosphere. Thereafter, a diamond coating is formed on the substrate by vapor-deposition method.

Abstract: Integrated circuit chip-to-chip interconnections are made via gold pads (24, 34) on each chip (101, 102) that are bonded to corresponding gold pads (14, 12) on a silicon wafer chip carrier (10). The pads on the chips and/or the pads on the carrier are characterized by texturing (roughening) with a feature size of the order of a micrometer or less, so that each of the pads on the chip can be attached to each of the pads on the carrier by compression bonding at room temperature-- i.e., cold-well bonding. In particular, the texturing of the gold pads on the silicon carrier is obtained by etching V-grooves locally on the surface of the underlying silicon carrier in the regions of the pads, thermally growing a silicon dioxide layer on the silicon carrier, and depositing the gold on the silicon dioxide layer.

Abstract: A production last (10) for the manufacture of shoes on a computer- controlled transfer path has a toe part (11) and a heel part (12) which are displaceable in relation to one another. The two last parts (11, 12) are held together by a closure (20). This consists of a flat metal part (21) which is fixed by means of screws (29) in one of the last parts (12) and has a slot (22) which extends between the two last parts (11, 12) essentially parallel to the cut surface (13). In the other last part (11), a stepped bore (14) is provided, in which a fork (23) is guided. This fork (23) has a fork head (23.1), the two legs of which extend over the flat metal part (21). In the fork head (23.1), a transverse pin (24) is mounted, which extends through the slot (22) and in this manner holds the two last parts (11, 12) together. A two- part receiving plate (30.1, 30.2) serves to fix the last (10) in the working stations of the transfer installation. In order to guarantee a secure and lasting adjustment of the receiving plate (30.1, 30.2) in a last made of plastic also, there is in each case made below and parallel to said plate in the last parts (11, 12) a bore (31.1, 31.2). These bores (31.1, 31.2) each receive a metal part (32.1, 32.2) which is provided with threaded bores (34). The fastening screws (33.1, 33.2) of the receiving plate (30.1, 30.2) engage in these threaded bores (34).

Abstract: The method of the present invention may be utilized with a National Language Support (NLS) data processing system which includes a plurality of sortable keys. Each sortable key within the data processing system is assigned an alphabetic key value, a diacritic key value, a case key value and a special character key value. After building these key values for each character or key within the system, a place value may be assigned to each unique character which is based upon these four values. Thereafter, when specifying criteria for a search through the data processing system all four key values may be specified, thus permitting a search to focus exactly upon a desired alphabetic value, diacritic character value, case value and special character value for the desired alphabetic string. Alternatively, in a second embodiment of the present invention, a "fuzzy" or "quasi" search may be implemented by searching for those characters or keys which match the desired alphabetic value but which ignore one or more of the other key values. That is, diacritic marks may be ignored or case distinctions may be ignored at the option of the system user. In this manner, a rapid and efficient search through a National Language Support (NLS) data processing system may be accomplished with selectable degrees of accuracy in the resultant match.

Abstract: A belt driving system having at least one roller for adjusting creep within a plurality of rollers. Creep detecting means provided at one end of the creep adjusting roller is rotated by torque of a flat belt in contact with the creep detecting means. Biasing means for biasing the flat belt toward the creep detecting means and roller-end displacing means for converting the torque of the creep detecting means to displacement of the end of the creep adjusting roller toward a predetermined direction so that the flat belt is moved to the direction contrary to the creep caused by the biasing means are provided. When the flat belt creeps, the creep contrary to the original creep is caused by the roler-end displacing means, and thus the original creep is compensated. Consequently, stable running of the flat belt is obtained and clear pictures of the electrophotographic machine can be also obtained.

Abstract: Aromatic bischloroformate compositions are interfacially converted to polycarbonates in a single step which includes capping with a monohydroxyaromatic compound. The reaction is conducted by adding an interfacial polycarbonate formation catalyst such as triethylamine and incrementally adding a base such as aqueous sodium hydroxide solution, without pH control, until the reaction mixture is non-emulsified. The amount of base to be added without pH control may be determined by titration. Further base is then added as necessary to provide a pH in the range of about 10-13.
