A fuel injection valve that can favorably reduce the film thickness of fuel ejected from an outlet of an injection hole without relying on increase of the fuel pressure, whereby atomization of fuel spray can be favorably promoted, is provided.A fuel passage (16) through which the fuel flows is formed in the interior of the fuel injection valve (10). An injection-hole plate (18) as a member that separates an injection space (20) into which the fuel is injected, from the fuel passage (16), is provided in which a plurality of injection holes (22) for ejecting the fuel from the fuel passage (16) toward the injection space (20) are formed. The injection-hole plate (18), as viewed from the outlet side of the injection hole (22), is formed with an injection-hole outlet-side groove (24) connected to the injection hole (22) in a region (inner wall surface 22b) opposed to a main flow direction of the fuel directed toward the injection hole (22) along an inner wall surface (18a) of the injection-hole plate (18). The injection-hole outlet-side groove (24) is formed so as to extend in a direction away from the injection hole (22).

A compact and highly accurate A/D converter includes series-connected computation cells, the number of which is equal to the number for bits in an output signal. The first computation cell includes a first comparison unit for subtracting a reference current from a first input current to generate a first current, and a second comparison unit for subtracting a second input current from the reference current to generate a second current. The second computation cell includes first and second comparison units having the same configurations as those in the first computation cell. The computation cells of latter stages have the same configurations as the second computation cell. Current mirror circuits included in the first and second comparison units of each computation cell generate the first and second currents. Each computation cell outputs a current having an absolute value in accordance with one of the first and second currents.

A web material feeding apparatus has a suction plate 24 provided near an outlet of a reservoir box 2. The suction plate 24 can be shifted in the direction across a feeding path for tip paper C, by operation of a motor 76. The feeding apparatus also has a sensor unit 96 provided at the upstream side of a receiving drum 12. The sensor unit 96 supplies a detection signal to a controller 120. When the controller 120 detects meandering of the tip paper C on the basis of the detection signal supplied from the sensor unit 96, the controller 120 actuates the motor 76 to shift the suction plate 24 to thereby correct the meandering of the tip paper C.

Provided is a digital-analog converter circuit that enables, for example, securing an improved accurate analog signal voltage and preventing increase in the circuit size. A first node of each individual unit is connected to a middle node of a one-order higher unit than a unit having that first node. A second node of the each individual unit is connected to one of the first and second nodes provided in the one-order higher unit than the unit having that second node, the one being on the side connected to a resister section set to an impedance value 2Z. A hierarchical structure can be formed in which an opponent connection point of the second node is selected by a hierarchy switch section, whereby the each individual unit is parallel connected to the resister section provided in the one-order higher unit and set to the impedance value 2Z. In correspondence to an input first-order bit signal (D0), an analog signal voltage (AV) corresponding to an output code (1) of digital data is output from a lowest-order bit unit (LU). In this manner, the D-A conversion operation is performed.
摘要:
It is intended to provide an A/D converter circuit with which, by using a clock signal, on the basis of an analog voltage inputted a predetermined time past, it is possible to select suitably comparators to be operated and comparators to be rested, and which has small consumed power. A parallel-type A/D-converter circuit 200 converts an analog voltage VIN to a digital value DOUT at intervals of a predetermined period by means of a clock signal CLK using chopper-type comparators 1–7. The comparators 1–7 can each be set by first and second setting signals CONT1A etc. to either of an operating state and a resting state. A comparator control circuit section 211 performs logical processing on the comparator outputs OUT1–OUT7 in the preceding conversion to generate the first and second setting signals CONT1A etc., and brings some of the comparators to the operating state and holds the remaining comparators in the resting state.
