IPC: G08G1/0969
Filed: 1998-07-01
Abstract: PROBLEM TO BE SOLVED: To further improve the effectiveness of the report by making an approach to the situation of reporting only caution points having a high possibility of passage, even if a route is not set. SOLUTION: Only for the situation that specified caution points, e.g. sharp curves and crossings exist in possible directions, in which a car may run into a junction but no running guidance may be given, i.e., along a road, the report is made for warning against caution points every approach to the caution point. If caution points in all directions are reported in the case when a plurality of running directions are can be expected for a junction, extra reports become too much for the user, and he will not be able to concentrate his attention to really necessary reports to result in reduction of the report effectiveness, but if the caution points to be reported are limited as described, the condition of reporting only those points having high possibility of passage can be approached to improve the report effectiveness.

Abstract: PURPOSE:To increase the content of electrolyte and improve quick discharge characteristics by mixing a conduction agent powder and a viscosity improver capable of being gasified at a temperature equal to or lower than a specified melting point, into a hydrogen occluded alloy powder, forming the resulting mass under pressure together with a current collection plate, and burning the resulting plate. CONSTITUTION:A hydrogen storage alloy powder, a conductor powder, a resinous binder powder, and a viscosity improver capable of being gasified at a temperature equal to or lower than the melting point the binder resin are mixed together. The mixed powder is formed under pressure together with a current collection plate and the formed plate is rolled. Then, the resulting plate is burned at a temperature equal to or higher than the melting point of the binder resin. Then, the binder resin powder particles are melted and bound together to form a three-dimensional net-like structure, thereby binding the alloy powder particles and retaining them. On the other hand, since the binder resin powder particles included in the formed plate are gasified, a large number of pores are produced. Therefore, a hydrogen storage electrode having an increased porosity is obtained and hence the content of the electrolyte impregnated therein is increased to improve the quick discharge characteristics.

Abstract: PROBLEM TO BE SOLVED: To ensure easy mounting/removal by opening insertion holes for an elevation cord in either forward or backward direction of a slat and revesing the direction of opening one insertion hole against the direction of opening another insertion hole. SOLUTION: As insertion holes 11 in slats 4 neighboring up and down are opened alternately in the forward and backward directions, if uniform force is applied to either forward or backward direction of the slats 4, an elevation cord 6 is free from removal from the insertion holes in all slats. Even if the diameter of the opening of the insertion hole 11 is larger than the diameter of the cord 6, the cord 6 is positioned at the corner of the insertion hole 11. When the slat 4 is removed, the cord 6 is pulled from the insertion hole 11 forward or backward of the slat 4 and removed out of the insertion hole 11 and then the slat 4 is pulled out of a ladder cord 3. When it is mounted thereon, the reverse step is applied. In this way, the removal prevention of the cord is ensured when normally used and easy mounting/removal is allowed when the slat is replaced or repaired.
