Title: Vehicle position detector
Inventor: YASUI NOBUHIKO
IPC: G01C21/00
Filed: 1988-06-06
Abstract: PURPOSE:To improve the accuracy for inferring the present position by usually inferring the present position from an earth magnetism detecting means and a running distance detecting means, and checking up whether magnetization exists or not and correcting an output value of the earth magnetism detecting means, when an abnormal ferromagnetic field has been detected. CONSTITUTION:Usually an azimuth in the advance direction is derived from an output value of an earth magnetism detecting means 11 at every prescribed time, a running distance is derived from an output of a running distance detecting means 10, and from these values, the present position is detected by a dead reckoning arithmetic means 13. When a vehicle passes through in a ferromagnetic field in a grade crossing, etc. in the course of running, and the direction and strength of an abnormal ferromagnetic field is measured from an output of the earth magnetism detecting means 11, an output variation quantity and a variation direction of the earth magnetism detecting means 11 are derived in a magnetization correction quantity arithmetic means 15, and the output of the earth magnetism detecting means 11 is corrected by using its output variation quantity and variation direction in an azimuth arithmetic means 12. In such a way, a new present position is inferred in the dead reckoning arithmetic means 13.

Title: Process for exhaust gas desulfurization by catalyst
Inventor: KAWAMURA KAZUSHIGE
IPC: B01D53/86
Filed: 1998-05-21
Abstract: PROBLEM TO BE SOLVED: To improve the reaction efficiency by flowing exhaust gas in a downflow stream to a catalyst layer in the case of removing sulfur dioxide in the form of dilute sulfuric acid from exhaust gas by bringing exhaust gas containing at least sulfur dioxide, oxygen and a water content into contact with a catalyst. SOLUTION: In the flue gas desulfurization process (a catalytic sulfurization process), exhaust gas containing at least sulfur dioxide, oxygen and water content is brought into contact with a catalyst to convert sulfur dioxide into dilute sulfuric acid and remove it from exhaust gas. In such a desulfurization process, exhaust gas is flowed in a downflow to a catalyst layer. Dilute sulfuric acid adhered on the catalyst surface is washed away downward by the process. As the washed-away dilute sulfuric acid is flowed down along the catalyst surface, the exhaust gas is preferably flowed in parallel with the surface in the vicinity of the catalyst surface, and also its flow velocity is preferably high on the catalyst surface. The flow velocity of exhaust gas on the catalyst surface of the catalyst layer, therefore, is set to 1-40 m/s, preferably 1-15 m/s.

IPC: G06F9/44
Filed: 1985-06-26
Abstract: PURPOSE:To attain the storage, reference and invalidity of a variable value at a high speed by providing a buffer storage device into a central processing unit to use the variable address, the final reference address and the set of variable values as elements. CONSTITUTION:When the value reference signal is sent from an IPU 7 via a RAM 5, a variable address storage 2 is first checked to decide whether the corresponding address is stored in the buffer storage or not. If said address is detected (coincidence of comparator 4), the desired value is read out of a variable value storage 3 and sent to the IPU 7 via an MDR 8. If no address is detected (discordance of comparator 4), a pointer chain is traced from the data of a main storage 1 by means of the buffer storage. The traced variable addresses are all registered to the buffer storage. When the value invalidating signal is sent from the IPU 7, the final reference address storage 6 is checked to invalidate the coincident addresses.
