Title: Drive control method for unmanned carrier
Inventor: KOBAYASHI HIROYUKI
IPC: G05D1/02
Filed: 1990-09-27
Abstract: PURPOSE:To improve the reliability and the safety of an unmanned carrier by comparing the detection data on a track detection sensor with the error data on a control circuit obtained before a steering action for calculation of the estimated error data and inputting these error data to each drive motor for the drive control of the unmanned carrier. CONSTITUTION:When an unmanned carrier runs on a guide track 1 including the rectilinear and curve parts, a track sensor 10 detects the carrier running of the track 1. The detection data (dn) obtained by the sensor 10 are inputted to a control circuit 9 and compared with the error data (dn - 1) on the circuit 9 obtained before a steering action and to be previously inputted. Then the estimated error data (dn + 1) is calculated and inputted to the drive motors 7 and 8 for control of the drive of the carrier. As a result, the control action delay of the circuit 9 caused by the detecting action of the sensor 10 can be eliminated. Thus the reliability nd the safety of the carrier can be improved.

Filed: 1987-10-14
Abstract: PURPOSE: To satisfactorily demonstrate capability of a heat exchanger by disposing the heat exchanger for heat exchanging between gas in an extraction pipe and cold water or a refrigerant cooled in an evaporator in the course of the extraction pipe. CONSTITUTION: Refrigerant vapor and noncondensible gas in an absorber 6 is sucked into an extraction chamber 26 through an extraction pipe 25 with the aid of an ejector action of an absorption solution injected from a pipe 27 with discharge pressure of an absorption solution pump 8. The condensible gas becomes air bubbles and flows down through a container 28 together with the absorption solution, and reaches a gas/liquid separation chamber 29 where it is floated and is accumulated in a collection chamber 30. When the noncondensible gas and refrigerant vapor are cooled with the refrigerant fluid in a heat exchanger 36, temperature is lowered to about 5 deg.C from about 40 deg.C.  Herein, if pressure and a volume are constant based upon a state equation of gas: PV=nRT, a molar number n of the gas is inversely proportional to absolute temperature T, so that a molar number R' is increased by about 13%. Thus, the noncondensible gas stored in the same volume as the extraction apparatus in the collection chamber 30 is increased by about 13% in the molar number. The noncondensible gas is exhausted to the outside of the absorption refrigerator with the aid of an exhaust pump 34.
