Title: Toner composition for developing electrostatic latent image
Inventor: ISHIYAMA MASAAKI
IPC: G03G9/097
Filed: 1997-04-09
Abstract: PROBLEM TO BE SOLVED: To prolong the service life of a filter or to unnecessitate the filter and to reduce the running cost of a printer by using a quat. ammonium salt compd. as an electric charge controlling agent in a positive charge type toner compsn. used in a flash fixing method. SOLUTION: In a positive charge type toner compsn. used in a flash fixing method and consisting essentially of a bonding resin, a colorant and an electric charge controlling agent, a quat. ammonium salt compd. is used as the electric charge controlling agent. The quat. ammonium salt compd. preferably contains an inorg. anion which is preferably an Mo or W atom. The pref. amt. of the quat. ammonium salt compd. is 0.1-5 pts.wt. based on 100 pts.wt. of the toner compsn. In the case of <0.1 pt.wt., satisfactory electrostatic chargeability is not imparted to the toner. In the case of >5 pts.wt., cost increases because the electric charge controlling agent is expensive.

Title: Fuel injection pump
IPC: F02M41/12
Filed: 1992-03-18
Abstract: PURPOSE:To constantly provide an optimum infection rate with easiness and high accuracy by connecting a fuel pressure chamber to low pressure chamber through a leakage passage, providing a control valve driven to open and close by an elctrostrictive actuator in the leakage passage and changing the fuel injection rate in accordance with the opening and closing of the control valve. CONSTITUTION:When a plunger 7 is moved forward, a fuel in a fuel pressure chamber 8 is pressurized, passed through a horizontal hole 17, a vertical hole 16 and an outlet slit 15, then, fed under pressure to an outlet port 18 of any one, and fed to a fuel injection nozzle. In this case, during the forward movement of the plunger 7, an annular groove 22 is opposed to a leakage hole 23, so that a leakage port 21 communicates with the leakage hole 23. Then, the injection rate of fuel is changed in accordance with the opening and closing states of a control valve 28. Namely, for example, when the control valve 28 opens, the fuel in the fuel pressure chamber 8 passes through a leakage passage 41 and flows out to a pump chamber 2, so that the fuel injection rate is lowered. Since the valve element 31 of the control valve 28 is driven to open and close by an electrostrictive actuator 30, the fuel injection rate can be arbitrarily changed with high accuracy.
