Title: Fuel pump and its manufacture
Inventor: ITO MOTOYA
IPC: F04D23/00
Filed: 1996-05-21
Abstract: PROBLEM TO BE SOLVED: To provide a fuel pump whose fuel discharge quantity can be regulated through a simple method and its manufacturing method. SOLUTION: The thickness of a housing 11 is set up so that in a state where an auxiliary housing 50 is not attached, the magnetic circuit of a motor section 30 may be magnetically saturated in the housing 11. The fuel discharge quantity of the fuel pump 10 is measured in the state where the auxiliary housing 50 is not attached, and this measurement value is compared with the required discharge quantity, and the auxiliary housing 50 whose plate thickness is selected so as to approach the desired discharge quantity is attached to the outer periphery of the housing 11 to increase the thickness of the whole of the housing for increasing effective magnetic fluxes ϕ and lowering the number of revolutions N. As a result, the fuel discharge quantity of the fuel pump 10 excessive in comparison with the required discharge quantity decreases.  Thus since the consumed electric power of the fuel pump 10 can be reduced, and the quantity of fuel returned to the fuel tank decreases, the vapor generation of the fuel can be controlled.

Title: Deodorizing device
Inventor: HASEGAWA ATSUSHI
IPC: A61L9/015
Filed: 1990-05-17
Abstract: PURPOSE:To prevent ozone from leaking to the outside without causing large-sized construction of an odor absorbing/decomposing part by furnishing a control means with an odor absorption command part, which commands high speed rotation of a fan and suppression of the ozone production amount, and a reproduction command part which commands low speed rotation of the fan and increase of the ozone production amount. CONSTITUTION:In the high speed operation mode in which the odor absorption command part of a control means 6 decreases the discharge current of a discharge electrode 3, reduces the ozone production amount, and turns a fan 2 at a high speed, the transit time in which the ozone passes through an odor absorbing/decomposing part 4 is shortened, so that the ozone catching rate of this part 4 will drop. However, the ozone production amount itself has been reduced, so that the ozone leak amount consisting of the product of the two is suppressed below the allowable level, and in case electric discharge is to be stopped, the ozone leak amount nullifies. On the other hand, the odor absorbing/decomposing part and reproduction command part of the control means increase the discharge current of the discharge electrode part to cause increase in the ozone production amount, and also the transit time for the ozone to pass thorough the odor absorbing/decomposing part is prolonged in the low speed operation mode in which the fan is turned at a low speed, so that the ozone catching rate of the odor absorbing/decomposing part is raised.
