摘要:
A double-break puffer-type compressed-gas circuit-interrupter is provided having a common piston-and-cylinder arrangement for simultaneously forcing a blast of compressed gas through suitably-disposed jet apertures into a pair of serially-established arcs, the operating arrangement being such that there occurs simultaneous operation of the piston-and-cylinder arrangement, together with opening motion of the bridging cross-bar, electrically and mechanically interconnecting the two movable contacts.An ancillary feature of the invention involves the provision of suitable arc-horns, associated with each of the break structures, so that the inherent looping of the electrical circuit through the circuit-interrupter results in electromagnetic repulsion forces, to exert an outward electromagnetic force exerted upon each of the two serially-related arcs. Preferably, laterally-disposed arc-splitters, formed of a suitable insulating material, accommodate the looping effect of the two arcs, and thus result in their considerable elongation around the spaced insulating splitters to thereby lengthen them and to attenuate the two series arcs.

An ECU executes a program including the steps of: setting a first throttle opening degree (S100), setting a low gear torque LTE based on an engine torque map for low gear having the first throttle opening degree and an engine speed (rpm) as parameters (S200), setting a high gear torque HTE based on an engine torque map for high gear having the first throttle opening degree and the engine speed as parameters (S300), setting a target engine torque TTE by combining the low gear torque LTE and the high gear torque HTE by using a correction ratio KGR determined by a gear step (S400), and controlling the engine to produce a required torque set by using the target engine torque TTE (S700). In this way a torque can be obtained in accordance with the engine speed.

A gear shift controlling apparatus of an automatic transmission for a vehicle has a synchronization-time engagement pressure correcting device that, before synchronization of gear-shifting, makes an increase correction of an engagement pressure of the disengaged-side engaging element by a first prescribed amount, to cause an input shaft rotational speed immediately before synchronizing of the automatic transmission to approach a rotational speed calculated by multiplying an output shaft rotational speed by a gear ratio of a gear after gear-shifting the automatic transmission.
摘要:
When determining whether to perform one shift, from among a downshift and an upshift to an adjacent gear speed from a predetermined gear speed after the other shift from among a downshift and an upshift was performed, a shift line switching portion switches a shift line from a shift line that is based on the speed ratio of the predetermined gear speed to a shift line that is based on the speed ratio after the one shift. Accordingly, a shift determining portion determines whether to perform the one shift using the shift line that is based on the speed ratio after the one shift, and that shift is executed.

The present invention provides an ink jet recording apparatus in which many components in a carriage-driving system are unitized into a carriage frame. The apparatus comprises a carriage loaded with a recording head for discharging ink from a plurality of nozzles, a carriage-driving device for driving the carriage, a bendable electric wire, and a carriage frame. The electric wire is bent from an apparatus body and mounted to the recording head and passes a printing signal to the recording head. The carriage frame arranges the carriage, the carriage-driving device, the recording head, and the electric wire at predetermined positions to form a unit. The carriage can reciprocate in parallel with the main scan direction along the longitudinal direction of the carriage frame. As a result, the recording head can be easily replaced, and the apparatus can be maintained without complicated work.
