Title: Collision preventing device
Inventor: YAMAMOTO TAKAYUKI
IPC: G08G1/09
Filed: 1999-02-02
Abstract: PROBLEM TO BE SOLVED: To prevent the rear-end collision of a subsequent vehicle to a large vehicle which is slowing down owing on an uphill of a steep slope by measuring an inter-vehicular distance, judging the danger degree of a rear-end collision and displaying data showing the danger of the rear-end collision when the danger degree is high. SOLUTION: A TV camera 8 image-picks up the road traffic video of a road 6 and transmits the video signal to a picture processor 9 through a video cable 10. The picture processor 9 executes the image processing of the inputted video signal, judges large size/small size, and always measures travel speed. When the picture processor 9 detects a high speed travel vehicle 7b after it detects a low speed travel vehicle 7a whose speed is lower than previously set one, it obtains time when the subsequent vehicle overtakes the preceding vehicle from the speed difference of the vehicles and an inter-vehicle distance. When it is shorter than time which is previously set, the danger of a rear-end collision is judged and an information display signal is sent to an information board controller 2.  The information board controller 2 displays information showing the danger of the rear-end collision to an information board 1 to the high speed travel vehicle 7b.

Title: Electrically erasable and electrically programmable read only memory
Inventor: MANZAA GIRU
IPC: H01L27/115
Filed: 1989-02-03
Abstract: PURPOSE: To provide an electrically erasable programmable memory, that is, EEPROM, which does not require a high current for programming, by using an enhancement transistor merged with a floating gate transistor. CONSTITUTION: A cell is readable at a low voltage. For example, a cell row is readable by applying +3V to a predetermined word line control gate, 0V to all the other word line control gates, 0V to all sources, and +1.5V to all drains. In this state, the source-drain path of the cell becomes conductive in an erased state or a non-programmed state (the cell having no electric charge on the floating gate thereof). That is, logic one is stored. A programmed cell (having a negative charge on the floating gate thereof and not programmed in a high threshold state) does not become conductive. That is, logic zero is stored.

Title: Carrying handle assembly for bag with flat bottom, its manufacturing method, and facilities for producing the same
Inventor: FURITSUTSU ATSUHERUPOORU
IPC: B31B19/86
Filed: 1993-02-16
Abstract: PURPOSE: To avoid the danger of removing a carrying handle even in case of carrying heavy load, by forming the carrying handle with a material bent to U-shape and adhering it to legs of two materials, which are arranged neatly at the top and adhered each other. CONSTITUTION: A carrying handle 17 is formed with a material bent to U-shape, and the legs of the carrying handle are adhered to legs of the two materials, which are arranged neatly at the top and adhered each other. Accordingly, the projecting legs of the material adhered each other (the other legs are connected to the flat bottom) constitute resultantly a holding part of the legs of the carrying handle 17. As a result, as tensile force is applied to the legs but is absorbed by an L-shaped material, concentration of the strain, which will cause the break, does not occur. Therefor, no danger of removing the carrying handle is caused even in case of carrying heavy load.
