Title: Fuel injection pump
Inventor: ASAYAMA KAZUHIRO
IPC: F02M59/46
Filed: 1996-10-16
Abstract: PROBLEM TO BE SOLVED: To provide a fuel injection pump capable of suppressing energy loss in converting the reciprocating motion of its plunger into force used for its fuel discharge. SOLUTION: A fuel injection pump 11 comprises a pump chamber 24 of which volume is adapted to be varied by the reciprocating motion of a plunger 20 and which communicates with passages T1 and T2. The passage T2 is provided halfway with a volumetric chamber 30 for its increased flow area of fuel. The volumetric chamber 30 has therein a discharge control valve 27 held at a position to cut off the communication between the pump chamber 24 and the passage T2 by the pressing force of a coil spring 28. When the plunger 20 is lowered fuel is sucked by way of the passage T1 into the pump chamber 24, while when the plunger 20 is raised the pressure in the pump chamber 24 is correspondingly raised.  If the pressure in the pump chamber 24 reaches an excessive pressure, the discharge control valve 27 moves against the coil spring 28 to suppress a pressure rise in the pump chamber 24 only with reduced energy loss.

Title: Control device for exhaust apparatus
Inventor: TODA TAKASHI
IPC: G05D7/00
Filed: 1990-10-13
Abstract: PURPOSE:To always control a valve with high stability and high speed response regardless of the opening degree state of the valve by only slightly controlling a valve when the opening degree of the valve is small and largely rotating the same when the opening degree is large. CONSTITUTION:A pressure adjusting valve 7 is provided to the exhaust passage 6 connected to a chamber 1. In the control unit for an exhaust apparatus controlling the valve 7, a multiplying circuit 22 multiplies the difference between the actually measured pressure value (a) obtained by monitoring the pressure in the chamber 1 and a set pressure valve (b) by the actually measured opening degree value (c) obtained by monitoring the opening degree of the valve 7. A mu-factor converting circuit 23 makes a mu-factor small when the product obtained by the multiplying circuit 22 is small and makes the same large when said product is large. The opening degree of the valve 7 is adjusted on the basis of the output signal of the mu-factor converting circuit 23. As a result, regardless of the opening degree state of the valve, the valve can always be controlled with high stability and high speed response.

Abstract: PURPOSE:To shorten a drying time by a method wherein a package tank is freezed in a drying circulation circuit, a fiber package with a low rate of moisture is filled in the tank during a drying operation so as to pass hot air, and a tank pressure is released after increasing a rate of moisture of the fiber package and the fiber package is transported out. CONSTITUTION:During an initial dehydration stage, changing-over valves 9 and 10 are closed, air sent into a drying tank 1 and a flowed out of a cooling device 5 is further sent to a condensing separator 8, where moisture in the air is separated. Upon completion of an initial dehydration stage, the changing-over valves 9 and 10 are opened, a changing-over valve 11 is closed, and a flow of air is sent to a package tank 12, resulting in that a dried fiber package in the tank 12 may absorb moisture in the air stream within a short period of time. In this case, the cooling device 5 is not operated. When a fiber package 14 reaches a limited moisture absorbing rate, the changing-over valve 11 is opened, the changing-over valves 9 and 10 are closed and a drying processing is continued. Inner pressure of the tank 12 is released to the surrounding atmosphere, an opening or closing lid 13 is opened and then the fiber package 14 which has absorbed moisture is replaced with dry fiber package. With such an arrangement, steam and cooling water are reduced in their consumption and then a productivity can be improved.
