摘要： A swash plate type axial piston pump improved in respect to wear or abrasion-resistant capability of sliding members of the pump adapted to rotate relative to each other for protecting them from rapid wearing even upon high rotation of the pump. The axial piston pump includes a housing (1), a rotatable shaft (3) supported rotatably within the housing (1), an axial piston pump including a cylinder block (15) mounted on the shaft (3) axially slideably therealong and co-rotatably therewith and a plurality of pistons (21) accommodated axially reciprocatively within a corresponding number of cylinders, respectively, which extend axially, being arrayed around the rotatable shaft (3), a swash plate (23) disposed for moving reciprocatively the pistons (21) in axial direction as the shaft (3) is rotated, and a plurality of sliding members which are incorporated slideably relative to one another for constituting parts of the pump. At least one of the plural sliding members such as the valve plate (31), the cylinder block (15), the shoe (25), the swash plate (23), the shoe holder (27) and the supporting member (24) is coated with a nickel-phosphor-Teflon layer by plating.

摘要： In a swash plate type axial piston pump, a swash plate 23 is fixed and supported in a cabinet while being inclined with respect to the center axial line of a rotary shaft 3. A cylinder block 15 having a plurality of cylinders 13 is attached to the rotary shaft 3 so that the cylinder block 15 slides of the rotary shaft 3 in the axial direction thereof and is rotated integrally therewith. Each one end of a plurality of pistons 21 is slidingly engaged with the cylinder 13 and the other end thereof is abutted against the swash plate 23 through a shoe 25. A valve plate 31 having a suction port 33 and a discharge port 35 is disposed so as to be abutted against the inner surface of the cabinet 1 and the bottom the cylinder block 15 so that a suction path 39 and a discharge path 41 in the cabinet 1 are selectively communicated with a pump chamber 14 in each cylinder through the suction port 33 and the discharge port 35. An operating oil is supplied to the sliding portion between the valve plate 31 and the bottom of the cylinder block 15 by a lubrication means. With this arrangement, since the operating oil is positively supplied to the sliding portion being rotated of the swash plate type axial piston pump, the sliding portion is sufficiently lubricated even if the pump is started to thereby prevent the dry state of the pump.

摘要： A current driven D/A converter sets an OFF control voltage (BIAS3) for turning off NMOS transistors M12P, M12N, M22P, M22N, M32P and M32N at a voltage close to an ON control voltage (BIAS2). This makes it possible to reduce the swing of the control voltage (ON control voltage−OFF control voltage) of the NMOS transistors, and hence to reduce the noise due to charge injections through parasitic capacitances, and noise of a ground voltage or power supply voltage due to flowing of discharge currents from the parasitic capacitances to the ground or power supply at turn off of the transistors, thereby being able to offer a high performance current driven D/A converter.

摘要： The fuel injection system includes an injector 7 to be electromagnetically driven, a control device 2 for outputting a drive signal having first current-carrying time T1 and second current-carrying time T2 to this injector 7, and a drive device 6 for passing a large current to open a valve of the injector 7 during the first current-carrying time T1 and passing a small current to hold the injector 7 in a valve opening state during the second current-carrying time T2. The system is constructed so that the first current-carrying time T1 is set to the time shorter than valve opening required time T0 from a current-carrying start of the injector 7 to full opening and this time difference is set to the value shorter than valve closing operation delay time from a current break of the injector 7 in the case of breaking a current in the first current-carrying time T1 to a start of a valve closing operation.

摘要： In a pipeline type A/D converter, a switch for sampling an analog potential signal has its other terminal in connection with an A/D converter, a D/A converter, a capacitor for subtraction. Even when frequency of the analog potential signal is raised such that input current is increased and a voltage drop is increased at the switch, there will be no error in the result of subtraction like in the conventional example where analog potential signal was directly input to A/D converter. Accordingly, a pipeline type A/D converter with low power dissipation and satisfactory frequency characteristics is obtained.
