Title: Hydraulic switching valve
Inventor: MOGI TAKESHI
IPC: F16K11/056
Filed: 1997-06-23
Abstract: PROBLEM TO BE SOLVED: To reduce supplied oil resistance between both ports so as to improve responsiveness by communicating a first and a second ports with each other and, when pressure oil is distributed between the ports, shorting all or a part of a supplied oil space by a shorting hole provided in a valve element. SOLUTION: When a controlled device and a pressure oil source 3 are communicated with each other, the output rod 34 of a solenoid 33 is protruded and, when a second ball 32 is pressed downward to a third valve seat 20, a valve seat 22 is displaced against the elastic force of a compression spring 24. Then, a second valve seat 19 and a conical projecting surface 31 are separated from each other, hydraulic oil sent into a second port 9 opens a check valve 25 and sent to the controlled device 2 through a communicating hole 21 and a first port 8. In this case, a plurality of shorting holes 35 and 35 are formed in the shoulder part of a bottomed cylindrical piston part 26 constituting the lower half of the valve element 22.  Thus, when the hydraulic oil is sent from the second port 9 to the first port 8, supplied oil spaces 30 and 30 are shorted by the shorting holes 35 and 35, and time necessary that pressure oil takes to reach the first port 8 is shortened.

Title: Hot runner mold
Inventor: MURAYAMA ASAHIKO
IPC: B29C45/32
Filed: 1992-06-24
Abstract: PURPOSE:To prevent a leakage of a resin and an intrusion of air at the time of mold opening in a stacking mold of a hot runner system. CONSTITUTION:An extension manifold 61 fixed to a main manifold of an intermediate mold is passed through a fixed mold. The extension manifold 61 is connected to a nozzle 6 of an injection molding machine at the time of mold clamping and separated from the nozzle 6 at the time of mold opening. When a resin is injected to a resin path 71 of the extension manifold 61 in a mold clamping state, a valve disc 76 is separated open from a valve seat 77 by the resin injection pressure. When a screw 7 is retracted backward after a dwell process, the valve disc 76 is drawn to the screw 7 until it is abutted against the valve seat 77 to be closed. Even when molds are opened thereafter, the pressure of the melt resin in the manifold 61 keeps the valve disc 76 closed.

Title: Air-fuel ratio controller for internal combustion engine
Inventor: URANISHI KOJI
IPC: F02M25/08
Filed: 1988-07-06
Abstract: PURPOSE:To keep off the worsening of drivability by calculating a decrement correction value for decrement of fuel on the basis of a difference between air-fuel ratio correction factors when the air-fuel ratio correction factor has become less than the specified value and at time just before a purge start. CONSTITUTION:A difference between an air-fuel ratio correction factor at a time when the air-fuel ratio correction factor has become less than the preset value by starting a purge of fuel to an engine inlet system and an air-fuel correction factor at time just before the purge start is found by a substruction means 102. On the basis of a difference between these air-fuel ratio correction factors, a decrement correction value for decrement of fuel is calculated by a decrement correction value calculating means 103. Next, a fundamental fuel injection quantity is compensated for decrement on the basis of this decrement correction value by an air-fuel ratio compensating means 104, while the air-fuel ratio correction factor should be forcibly set to the value just before the purge start. Then, the decrement correction value after being corrected is made smaller by degrees. With this constitution, even if an accelerator pedal is operated during the purge, an air-fuel ratio is in no case rarefied too much and, what is more, drivability will not be worsened at all.
