Title: Optimum route searching method for mobile robot
Inventor: ONISHI MASANORI
IPC: G06F19/00
Filed: 1991-05-17
Abstract: PURPOSE:To search a shortest-time route and to evaluate the change of an advancing direction as time having real actions by deciding the evaluation of route selection based on time required for move in the case of searching the route based on stored map information. CONSTITUTION:An evaluation function for selecting a node Vj to next advance from a node Vi as the reference of the route search is defined by an expression as follows; H (Vi,Vjx)=Tgx+Tlx+Tdx+Tox. In this expression, Vjx shows a candidate node to be next selected and tgx shows time for travel a linear distance from a candidate node Vjy to the destination (goal). Tlx shows time for traveling from the node Vi to the candidate node Vjx, Tdx shows posture change time for traveling from the posture of the node Vi to that of the candidate node Vjx, and Tox shows time to limit the other travel. Thus, a CPU 2 can search the shortest-time route and can evaluate the change of the advancing direction as the time having real actions. Further, it is possible to consider a time loss caused by any special condition.

Title: Preparation of glaze with highly stable viscosity
Inventor: AIKAWA MICHIO
IPC: C03C8/16
Filed: 1979-09-06
Abstract: PURPOSE: To obtain glaze causing a slight decrease in the viscosity even in the summer period by adding carboxymethylcellulose (CMC) and a hydroquinone compound to glaze.  
     CONSTITUTION: To glaze are added CMC by 0.3W10% to the amount of the solid in the glaze and a hydroquinone compound by 1W5% to the amount of the CMC. As the compound hydroquinone is industrially and easily available and practical. Solid separation is not recognized in the resulting glaze even after 10 days, and the viscosity is slightly decreased. Thus, the viscosity of the glaze is stabilized, and the amount of the glaze stuck to tiles or the like is made uniform. Accordingly, the adhesion of the glaze to the tiles is enhanced to enable stable operation.
