Title: Intake passage for fuel injection engine
Inventor: MACHINO ATSUKI
IPC: F02M29/00
Filed: 1997-02-03
Abstract: PROBLEM TO BE SOLVED: To prevent a lowering of engine output by a method wherein a throttle valve is disposed in a throttle body and a turbulence suppression means to suppress the occurrence of turbulence of distribution of intake air at a specified period is arranged in an intake passage. SOLUTION: A throttle valve 20 is disposed in a throttle body 10. During the low opening of the throttle valve 20, a turbulence suppression means 22 to suppress turbulence of distribution of intake air during the low opening of the throttle valve 20 is arranged in an intake passage 14. During the low opening of the throttle valve 20, turbulence occurs to intake air after the passage of intake air through the throttle valve 20. Further, occurring turbulence flows in a collector 24 situated downstream, speed energy of intake air is reduced at a collector 24, and turbulence of intake air is dissolved, intake air flows to a spot situated downstream. In this way, a flow of intake air is improved. This constitution stabilizes an engine output and prevents the increase of a hazardous component in exhaust gas.

Title: Piler for plate-shaped member
Inventor: MORI KIICHI
IPC: B65H33/02
Filed: 1980-03-18
Abstract: PURPOSE: To enable plate-shaped members to be continuously piled and delivered by providing a vertically movable lower support below an upper support and further providing below the lower support a seat holder moving vertically between rolls of a roller conveyer.  
     CONSTITUTION: When a plurality of cut plates 3 are piled, an upper support 9 retreats a claw 5 to shift the cut plates 3 to a lower support 11 and then immediately returns to receive the cut plates 3. The lower support 11 descends little by little every time it receives the cut plates 3. When the lower support 11 descends to a predetermined position, it retreats the claw 5 to shift the cut plates 3 to a stand-by seat holder 6 and then returns to the original reception starting point. After the return of the lower support 11, the seat holder 6 serves as the lower support to receive the cut plates from the upper support 9 while descending little by little. When a predetermined amount of the cut plates is piled, the seat holder 6 descends abruptly to transfer the cut plates 3 to a roller conveyer 8.

IPC: B01D61/16
Filed: 1987-02-17
Abstract: PURPOSE:To permit selective determination of free chlorine and chloramine by separating the chloramine by using a microporous high polymer from each of a sample liquid added with a free chlorine decomposing agent and sample liquid added with an ammonia soln. and determining the chloramine. CONSTITUTION:Carrier liquids added with iodide ions or bromide ions are passed in microporous 'Teflon(R)' pipes 8, 9. The sample liquid is fed by a pump 10 and a divided to two flow passages by a two-way valve 11a. One thereof is added with the soln. of the free chlorine decomposing agent and is sent to an outside pipe 5 of a permeation part 2 by a pump 13. The other is added with the ammonia soln. and is sent to an outside pipe 6 of a permeation part 3 by a pump 14. The chloramine remaining in the permeation parts 2, 3 permeates to the inside of the pipe 8 and enters the carrier liquid, thus generating iodine or bromine. The amt. of the iodine or bromine generated is, therefore, measured by a spectrophotometer 21. The quantity of the free chlorine in the sample liquid is known from a difference in the measured value with the reactive liquid introduced from the respective permeation parts and the quantity of the chloramine is known from the measured value with the reactive liquid introduced from the permeation part 2.
