Abstract: Transportation System Having a Cable Drawn Vehicle Abstract A passenger carrying vehicle, supported on air cushions in a guideway, is propelled back and forth in that guideway by a cable.  A motor is at one end of the guideway and pulls the cable.  The cable is part of a closed loop; having two parts, that extend along the same side of the guideway.  Rollers, positioned along that side of the guideway, support each length of the cable.  In curved portions of the guideway, where the vehicle is turned left or right, the roller that supports that length to which the car is attached is oriented to support the combined horizontal and vertical loads on the cable as the car is pulled around the turn.  The vehicle comprises two cabs. These cabs are pivotally inter-connected, allowing them to flex or pivot vertically relative to each other and allowing the vehicle to conform to variations in the contour of the guideway, thereby improving the lift characteristics of the air cushions.

Abstract: RECORDING METHOD AND APPARATUS THEREFOR     ABSTRACT OF THE DISCLOSURE             A recording method and apparatus therefor make the recording of images in the following process:  A powder-like toner having a high electric resistivity and a charge retention property is held on a donor and is brought into contact with a multi-stylus electrode.  A pattern signal is applied to the multi-stylus electrode and the toner is elec-trically charged or quenched by the charge injection of the multi-stylus electrode and a charge distribution is formed in the toner on the donor, corresponding to the pattern signal.          The charge distribution is used for the formation of a visible image. For example, by transferring the toner selectively to a recording sheet in accordance with the charge distribu-tion, a visible pattern corresponding to the pattern signal is obtained on the recording sheet.  The visible pattern can be recorded on an electrically conductive recording member or a recording member having uneven surface by utilizing an image transfer medium.  By transferring toner to a latent image bearing member on which a latent electrostatic image is formed, a visible pattern modified by the pattern signal can be obtained.

Abstract: A B S T R A C T   A contact structure for securing a semiconductor substrate to a mounting body in a semiconductor device.  A multi-layered electrode formed on a surface of the semiconductor substrate, the multi-layered electrode comprising a chromium-nickel alloy layer formed on the surface, a nickel layer formed thereon and a noble metal layer selected from the group consisting of gold, silver, palladium and platinum formed further thereon, a solder layer, and a mounting means for holding the semiconductor substrate thereon, the solder layer soldering the multi-layered electrode to the mounting means, thereby bonding the semiconductor substrate to the mounting means.  The foregoing construction has the features that there are substantially no voids at the solder layer as a result of good wetting of the noble metal to the solder layer; that the effective bonding area increases as a result of decrease of voids, resulting in decrease of thermal resistance by 10 to 20%; that secondary breakdown voltage increases by about 10%, thereby increasing reliability; that the bonding force is drastically increased; that process control in the soldering step becomes easier; that undesirable Sn-Ni formation is suppressed, thereby improving resistivity to thermal fatigue; and that oxidation of the surface of the multi-layered electrode is eliminated, thereby eliminating the necessity for preliminary treatment before soldering.

Abstract: Abstract of The Disclosure A new process is disclosed which enables an effi-cient and effective recovery of dissolved metals from a spent electroless or immersion plating solution and without the use of a permeable membrane.  This is accomplished, by pro-viding a bath of the spent solution in which an insoluble metal anode and a cathode of an aluminum shape are introduced, by adjusting the solution within a selected range of pH of about 2 to 12, by applying electric current to the electrodes only in an amount sufficient to restrain or inhibit chemical dissolution of the cathode by galvanic action, and impor-tantly, by maintaining the selected pH throughout the process. A directly usable pure metal deposit in the form of a film or slab is deposited on the aluminum cathode that has an adhering but peelable relation thereon.  The aluminum cathode may be in the form of any suitable shape, such as a sheet, rod, plate, or wire.  In a conventional process, the metal salt in solution is electrodeposited on a cathode made of the same metal that is to be extracted.  However, such a process has been found to be unsatisfactory in that a coarse, powdery deposit in the nature of a metal oxide or compound results and at a very low efficiency.  The deposit has to be further processed to obtain the desired pure metal.  The process herein involved provides a rate of metal deposition that is considerably in excess of the 100% that can be achieved with electrolysis governed by Faraday's law, and is not based on electroplating deposition.
