Title: Movement analyzer for mobile object
Inventor: MINOWA SHIGERU
IPC: G01C21/00
Filed: 1998-10-27
Abstract: PROBLEM TO BE SOLVED: To prevent an error of movement information from increasing even if GPS satellites are switched by comparing GPS movement information with predicted values of GPS movement information calculated one period before and performing filtering based on GPS movement information corrected with the difference thereof. SOLUTION: A GPS receiver 14 operates the position and the speed (referred to GPS movement information) of a mobile object at a positioning coordinate group based on a selected GPS satellite group. If the combination of GPS satellites changes during positioning causing variation in satellite switching information, a GPS movement information correcting section 15 calculates the difference between the GPS movement information and predicted values of GPS movement information calculated when a filter is updated one period before and stores it as a GPS movement information correction value data base 17. The GPS movement information is then corrected with the GPS movement information correction value and delivered to a movement analyzing section 16.  Since the corrected GPS movement information is matched apparently with the mobility of a mobile object, subsequent filtering can be sustained stably at a filtering section 19.

IPC: B09B3/00
Filed: 1996-10-11
Abstract: PROBLEM TO BE SOLVED: To directly fire a combustible waste as it is in air to convert into a carbide by mixing a combustible waste and a soln. containing metal ions and firing the mixture in air at temp. higher than the carbonization temp. SOLUTION: For example, a bean-curd refuse by about 90wt.% is kneaded with about 5wt.% aluminum phosphate soln. in a mortar to form a sphere of about 3cm diameter.

When the temperature is low, these through holes 31, 32 are shifted to superpose with each other due to the spring 6 action and hence, the area of the through holes is kept small. On the other hand, when the temperature rises, the spring 7 is extended to superpose both holes 31, 32 and hence, the through-hole area is kept large and the volatilized quantity of deodorant 8 is increased. Accordingly, it overcomes the odor in the chamber to generate the deodorizing effect and then the chamber is kept in a good environment.

Filed: 1988-12-02
Abstract: PURPOSE:To efficiently perform the heat transfer by a method wherein a recessed parts or holes are provided on the exposed part of a temperature sensing rod in a low pressure refrigerant path to increase the heat transfer area and make the refrigerant flow turbulent. CONSTITUTION:When the temperature in a cabin rises and the temperature of the refrigerant flowing into a low pressure refrigerant path 11 rises, the gas 26 expands to which heat is transferred through a temperature sensing rod 3, a stopper 22 and a diaphragm 21, and the diaphragm 21 is displaced downward. This displacement causes a valve member 6 to be pushed down, and the flow rate of the refrigerant is increased which flows towards an outlet of an evaporator through an atomized refrigerant flow path 13. When the temperature in the cabin falls, the flow rate of the refrigerant is reduced by the reverse actions. By this constitution, the heat transfer is improved and wrong operation can be avoided because the heat transfer area is increased by side holes 34 provided on an exposed part 31, the refrigerant flow is made turbulent by the side holes 34, and the heat transfer distance is shortened by center holes 31.
