Title: Vehicle travel guiding device
Inventor: MATSUMOTO YOSHIYUKI
IPC: G08G1/0969
Filed: 1991-12-18
Abstract: PURPOSE:To select the optimum route from a start point to a destination according to a traffic condition. etc., by retrieving another route different from a previously retrieved route next when plural routes are retrieved sequentially by retrieving a rank corresponding to the degree of cost on a line segment from the start point to the destination. CONSTITUTION:When it is decided that a retrieved route is inadaptable due to the traffic condition, etc., by the input operation of an operation device under the control of a signal processor, the retrieved route can be cancelled. When the retrieved route is cancelled, the signal processor retrieves the route which minimizes the cost of the line segment from the start point to the destination set on a road map next. At that time, processing to increase the cost of the line segment on the route A retrieved previously apparently is performed so as to retrieve another route B different from the route A cancelled previously next, which prevents almost the same route as the route A retrieved previously from being retrieved.

IPC: B29C48/43
Filed: 1998-12-25
Abstract: PROBLEM TO BE SOLVED: To reduce the mechanical cost due to the exchange of sections by a method wherein a housing jacket is divided into one or more shorter sections and longer sections including passages between a material inlet and a material outlet under the condition that the length of the longer section is set to be smaller than the outside distance of the section. SOLUTION: A housing jacket ranging from an end plate 7 to an end plate 8 is composed of radial divisions or of a charging section 13, a first shorter section 14, a first longer section 15, a second shorter section 16 and a second longer section 17. At the top part of the charging section 13, an inlet 18, through which a processing material is charged to a shape including main shafts 4, is provided. The lengths of the longer sections 15 and 17 are B, those of the shorter sections 14 and 16 are respectively C and D. In addition, the length B is set to be smaller than the distance A of the housing jackets of the longer sections 15 and 17 or of the end plates 7 and 8. In this case, the distance A means the closest distance between the sides opposite to each other in the outside outlines of the longer sections 15 and 17 or the end plates 7 and 8.  Since severe wear develops in a passage, through which solid additives are charged to the processing material, for such a passage, a shorter section is employed. Thus, wears are made smaller, the number of times for the exchange is reduced and the running cost of a machine can be reduced.
