Abstract: A series of N data items are sequentially received and stored in respective N storage locations of a first memory according to the order of arrival. The ranks of the N data items are determined according to their relative values to each other. Corresponding to the stored data items, the address number of the first memory storage locations of the corresponding data items are stored in respective storage locations of a second memory according to their ranks. The storage locations of the second memory are arranged in sequential order of ranks so that the first memory address numbers are sequentially arranged in the second memory in the order of the ranks of the corresponding data items. A sequence of additional data items is received and their ranks are determined relative to the values of data items stored in the first memory. If the rank of each additional data item is determined to be higher than the lowest rank of the stored data items, the additional data item is used to overwrite the lowest rank data item. The first memory address number of the additional data item is stored in the second memory according to the rank of the additional item by moving existing address numbers and discarding the address number of the overwritten data item. The address numbers stored in the second memory are sequentially read and the contents of the first memory are read.

Title: Outboard Motor, and Engine Thereof
Inventor: KOISHIKAWA KOUJI
IPC: F02F1/10
Filed: 1994-11-18
Abstract: An outboard motor body case is supported on a swivel shaft  through  a  connecting  member.  The  swivel  shaft vertically swingable about a tilting shaft. An engine is mounted at an upper portion of the outboard motor body case, with a crankshaft thereof being directed vertically, and  a  flywheel  is  mounted  at  a  lower  end  of  the crankshaft ant disposed between an engine block and the connecting  member.  A  dynamo  is  mounted  within  the flywheel, and a starter motor is engaged with a ring gear which is formed around an outer periphery of the flywheel.          Thus, since the flywheel having a large weight is mounted at the lower end of the crankshaft, the position of the gravity  center   of   the   outboard  motor   is   lowered.          Therefore,  it is possible to easily perform a tilting-up about  the  tilting  shaft  with  a  small  force.  Moreover, since the flywheel is mounted on a power taking-off side of  the  crankshaft,  the  torsional  vibration  of  the crankshaft can be reduced.

Title: System and method for transplantation of cells
Inventor: VOGT PETER M
IPC: A61K35/36
Filed: 1993-06-11
Abstract: Gene transfer of genetic material with viral vectors or plasmids, in combination with a wound treatment chamber, into keratinocytes, especially those including a high percentage of epidermal stem cells, has been demonstrated to be particularly effective as a means of implanting genetically engineered cells and obtaining long term survival. By employing the wound chamber system, direct in vivo gene transfer can also be done to exposed cells in an open wound. Skin stem cells which are located in the hair follicles are used to greatly enhance long term survival. The use of the wound chamber system for gene transfer also allows non-invasive assessment of the success of transfer by assaying for the presence of the expressed protein in wound fluid, in contrast to the prior art use of invasive techniques, such as biopsies, in order to achieve the same assessment of early expression. A wide variety of proteins and materials can be expressed, either for secretion into the general blood and lymphatic system, or to alter the properties of the protein, for example, to not express proteins eliciting an immune response against the transplanted cell.

Abstract: A gas fireplace has a set of artificial logs. The logs rest on top of a burner. The burner is formed from top and bottom metal sheets. The sheets are sealed together around a channel matched generally to the prospective position of the logs. A gas orifice feeds gas into the channel, while gas ports in the top sheet release the gas. The gas ports are positioned to match the final position of the logs. The channel is formed by creating a depression in the bottom sheet using a press with a general purpose stamping die moving in the pattern of the channel or a single hit special purpose die, or a rolling die moving in the pattern of the channel, or by the bottom sheet being moved across a stationary rolling or beading die in the pattern of the channel.  Secondary air holes feed air through the burner adjacent to the channel and the gas ports. The burner has a low profile, is manufacturable using conventional sheet metal techniques, and the ports, channel and holes may be redesigned for different fireplace characteristics. The logs may be replaced by or used in combination with other decorative fire material such as artificial coal or simulated embers. One or more recesses may be formed in the top sheet into the channel for recessing at least those gas ports that would be visible through the log set and for receiving alternate decorative fire material for hiding the ports
