Filed: 1979-09-07
Abstract: PURPOSE: To prevent the deterioration of the adsorptive capability of the second tower, as used in a pressure-oscillating adsorption method, or the lowering of the concentration of unadsorbed components in product gas by a method in which after a concentration gradient is formed for unadsorbed components in the first tower and a constant pressure is reached in the tower, a product gas is discharged.  
     CONSTITUTION: In the manufacture of oxygen-rich gas by removing nitrogen from air, for example, air is supplied through the valve 15 from the bottom of the tower when a given pressure is reached in the tower 10 in order to maintain the pressure of the tower, while a product gas is taken through the valve 11 out of the top of the tower. The product gas is flowed into the product tank 40 through the pipe 45 at first, but after the lapse of a given period of time, is sent to the top of the tower 20 by closing the valve 11 and by opening the valves 12 and 20. After the valves 24, 24', and 24" are orderly switched to the concentration gradient of oxygen which becomes smaller from the top toward the bottom in the tower 20, the valve 25 is opened to send air to the bottom in order to raise the pressure of the tower 20 to a given pressure. Then, the same operation is conducted at the towers 20 and 30, and the valve 17 is opened at the tower 10 to reduce the pressure of the tower to atmospheric pressure for the desorption and regeneration of adsorbent.

Abstract: PURPOSE:To maintain the high pressure air of an air bomb to a prescribed pressure by a simple constitution by opening and closing an air guiding passage to a control chamber by a valve body interlocking with the reciprocating movement of a diaphragm through a lever and reducing the pressure to a constant prescribed pressure. CONSTITUTION:A diaphragm 4 partitions the internal part of a pressure reducer main body 3 to a control chamber 5 and a back chamber 6. The high pressure air of an air bomb is reduced to the prescribed pressure according to the differential pressure force between the control chamber 5 and the back chamber 6, the tension of the diaphragm 4, and the balance of the load of a spring 19. The air of the control chamber 5 is fed to a mousepiece from a connecting pipe 18 and an internal pressure is lowered, and then, the diaphragm 4 is moved to the control chamber 5 side to rotate a lever 14 clockwise, thereby, a valve body 15 is opened and the high pressure air is guided to the control chamber 5 from an air guide passage 12. When the internal pressure of the control chamber 5 is raised, the diaphragm 4 is moved to the back chamber 6 side to close the valve body 15, thereby, the internal pressure of the control chamber 5 is maintained to a constant pressure.

Title: Preceding vehicle recognition method by scanning laser reader
Inventor: HIROSHIMA YASUHISA
IPC: G01S17/93
Filed: 1993-04-19
Abstract: PURPOSE:To accurately judge whether or not a vehicle is travelling on the same lane by repeating the arithmetic operation of a certainty degree each time the position coordinates and relative speed of a preceding vehicle candidate are calculated and cumulatively adding difference between the certainty degree and a reference value. CONSTITUTION:Adaptaion functions used in the arithmetic operation of the certainty degree are the function F1 (Vsk) of the difference between a driver's own vehicle speed vector Vs and the relative speed vector Vk of the preceding vehicle candidate and the function F2 (¦LK>>) of positional deviation quantity ¦LK>> in the vehicle width direction of the preceding vehicle to the driver's own vehicle and the certainty degree is calculated by using the functions. Then, the arithmetic operation is repeated, the difference between the certainty degree and the reference value is cumulatively added and whether or not the added total value is larger than the evaluation reference value of rear-end collision risk is judged. When it is smaller, it is judged that the preceding vehicle as an object is travelling on the same lane. When it is larger, it is judged that the preceding vehicle is not on the same lane and vehicle control for evading danger is not performed. Thus, vehicle travelling on the other lane and the vehicle parked on a shoulder, etc., can be discriminated.
