Title: Fuel injector
Inventor: MARUKO ARUFUREEDO GANSAA
IPC: F02M63/02
Filed: 1987-09-25
Abstract: The fuel injectors (4) of an internal combustion engine (2) are connected to a pump (10) by means of fuel supply lines (12) which open into the high-pressure part (34) of the injectors (4). The cross-sectional area of the fuel connection (12, 34) between the pump (10) and the injection orifices of the injectors (4) is substantially bigger than the total cross-sectional area of all of the injection orifices of an injector (4). An unrestricted flow path for the pressurized fuel is provided between the pump (10) and the area immediately upstream of the injection orifices. Due to the small pressurized volume of the system, the transient behaviour of the injection system is fast and can easily be matched to the needs of a particular engine application.

Abstract: PURPOSE:To easily produce the excellent liquid crystal oriented films by dropping the soln. of a heat resistant high polymer onto a water surface, then decreasing the area of the water surface, thereby compressing the soln. to form a thin film, bringing a solid substrate into contact with the thin film and transferring the thin film to the substrate. CONSTITUTION:Transparent electrodes 2 consisting of the patterns of 'NESA(R)' film are formed on the glass substrate 1 and a silicon oxide film 3 is deposited by evaporation thereon. The soln. of the heat resistant high polymer having >=120 deg.C glass transition point and a protonic hydrophilic group in the molecule is dropped onto the water surface; thereafter the water surface area is decreased to compress the soln. and to form the thin film. The substrate positioned approximately level is brought into contact with the thin film and the thin film is transferred onto the substrate. The substrate is inclined and is gently risen. This operation is repeated to accumulate 3 layers in total of the thin films of the heat resistant high polymer. The liquid crystal oriented films 4 are thus formed. The oriented films are then incorporated into a liquid crystal cell by using a sealing agent 5 and a ferroelectric liquid crystal is injected therein to form a liquid crystal layer 6. The liquid crystal oriented films having the excellent liquid crystal orientability are thus easily produced.
