Title: Fuel injection control device for engine
Inventor: TAKAHASHI SUSUMU
IPC: F02M59/20
Filed: 1997-08-29
Abstract: PROBLEM TO BE SOLVED: To provide a fuel injection control device suppressing the pressure fluctuation of a common-rail storing fuel by uniforming the discharge of fuel delivered from a plurality of pumping chambers of a fuel pump. SOLUTION: Common-rail pressure lowered by fuel injection performed by No. 2 injector, for instance, is recovered to pressure Pf (2) by fuel delivered from a pumping chamber provided with No. 3 piston. The difference from common-rail pressure Pf (1) recovered after preceding fuel injection is correlative to the discharge of each corresponding pumping chamber. On the basis of the difference of common-rail pressure recovered by fuel from the pumping chambers operated differing in time, the discharge of fuel delivered from the pumping chamber is increased/decreased to control the recovery pressure of a common- rail.

Title: Field emission electron gun
Inventor: KUBOZOE MORIKI
IPC: H01J37/04
Filed: 1985-11-05
Abstract: PURPOSE:To make it possible to perform the adjustment of an axis by operation from outside as an electron gun housing remains mounted, by providing magnetic poles near an FE chip to apply a two-dimensional magnetic field, and adjusting the magnetic field by operation from outside. CONSTITUTION:Magnetic poles 19, 19' welded to a spacer 20 to withstand a vacuum, electromagnets 18, 18' attached to a circular yoke 17 and the yoke constitute a magnetic circuit. The polarity of the magnets 18, 18' is such that an electron beam emitted from an FE chip 4 is deflected rightward or leftward as to the drawing by a magnetic field generated by the magnetic poles 19, 19'. A similar magnetic circuit extending perpendicularly to the drawing is provided by using the yoke 17 in common to the former magnetic circuit. The magnetic intensity of the electromagnets 18, 18' and other electromagnets, which act perpendicularly to the former, is increased or decreased to two-dimensionally deflect the electron beam in an optional direction. Although a magnetic field is generated because of the presence of the wall of an electron gun housing between the electromagnets 18, 18' and the magnetic poles 19, 19', the magnetic field does not hinder the adjustment of the axis of the electron beam because the magnetic field is distant from the beam.

Title: Refrigerant compressor
Inventor: ISHIDA TAKANORI
IPC: C10N40/30
Filed: 1997-09-12
Abstract: PROBLEM TO BE SOLVED: To provide a reliable refrigerant compressor by optimizing an assembly lubricant used at the time of the assembly of the refrigerant compressor so as to prevent the sliding parts in the refrigerant compressor from being initially worn at the start of the compressor and by suppressing the starting failure of the refrigerant compressor and the occurrence of substances clogging a cooling system. SOLUTION: A refrigerant compressor is structured so that 50 capacity % distillation temperature is 400 deg.C or higher and it uses a synthetic fluid base oil having an ether or carbonate structure in its molecules as an assembly lubricant. In this case, it is better to use the assembly lubricant containing at least one or more organic phosphoric acid compounds of 0.01 to 1.0 wt.% between acid phosphoric acid ester and phosphorous acid ester. Thus the initial wear inside a refrigerant compressor at the start of the compressor can be prevented, and the starting failure and the occurrence of substances clogging a cooling system can be suppressed.

Title: Control circuit for variable capacity pump
Inventor: NAGAI AKIYUKI
IPC: F15B11/028
Filed: 1989-09-25
Abstract: PURPOSE:To eliminate hysteresis in pressure control characteristics around the lowest discharge pressure and achieve a correct constant pressure control in spite of a large flow by applying feedback control to a servo cylinder by a pressure detecting signal of a discharge line on the secondary side of a sequence valve. CONSTITUTION:An electromagnetic proportional control valve 8 is provided in a pilot line 7 from a discharge line 4a on the primary side of a sequence valve 5 to a servo cylinder 3, and a detection signal Vf from a pressure sensor 9 for detecting the pressure of a discharge line 4b on the secondary side of the sequence valve 5 is subtracted to output from a desired discharge pressure instructing signal Vo by a subtracter 10, to output a deviation signal Ic to the electromagnetic proportional control valve 8. The discharge pressure of a variable capacity pump 1 and the pressure at the secondary side discharge line 4b can thus be controlled to be less than the cracking pressure of the sequence valve 5, and hysteresis in the pressure control characteristics in this range can be eliminated almost completely, so the effects of pressure loss at the sequence valve 5 can be eliminated, thereby a correct constant pressure control becomes possible for a large flow.

Title: Thermal recording method
Inventor: ONISHI TOSHIICHI
IPC: G11B7/24035
Filed: 1985-11-07
Abstract: PURPOSE:To enable the reproduction of a medium tone by using a recording material which is varied from a transparent state to a slightly-opaque state when heated to a prescribed temperature and is held in this state and then restored to the transparent state again when cooled down gradually, and by controlling an amount of heating of a heating body for recording. CONSTITUTION:An image forming sheet 2 is constructed of a substrate 2a formed of a synthetic resin film and a high-molecular recording material 2b superposed thereon. A pulse current generated by a pulse generator 3 is impressed on a heating body 1, and a visible image is formed with the length and amplitude of the pulse current varied. The high-molecular recording material is constructed of a thin layer formed by blending stable polymers of two kinds or more. When the image forming sheet 2 which is in a transparent state (transmittance a1) before the start of heating is heated, the transmittance decreases at a temperature T1 or above and the material gets into a light-opaque state. At a temperature T2, the transmittance turns to be a2. When the material is heated to a temperature T3, a transmittance a3 of one medium tone can be obtained. When cooled down gradually thereafter, the material can be restored again to the transparent state of the transmittance a1.
