摘要:
A vehicle engine control apparatus provides rotational speed synchronization control during a shift operation. A shift operation detecting component detects a shift position resulting from a manual shift operation of a manual transmission connected to an engine. A vehicle speed detecting component detects a vehicle speed. The computing component computes an input side transmission rotational speed value based on the vehicle speed and a gear ratio. A driving intent determining component determines a driver's driving intention. A rotational speed synchronization control component performs rotational speed synchronization based on a first target engine rotational speed value that is smaller than the input side transmission rotational speed value when a clutch is disconnected and a deceleration intention exists by the driver, and based on a second target engine rotational speed value that is equal to the input side transmission rotational speed value when the clutch is disconnected without the deceleration intention.

An engine torque control device is configured to provide increase engine output torque during shifting, with excessive engine output torque being prevented while shift shock is reduced. The engine torque control device has an automatic transmission control section that controls an automatic transmission and an engine output torque control section that performs a torque increasing control of an engine output torque to increase the engine output torque during a downshifting so that an actual engine speed will substantially approach a target speed. The allowable time for torque increasing control is set according to the amount of torque increase. If the increase in engine output torque is below a specified value at the point when the allowable time has elapsed, the torque increasing control is continued, but if the torque increase is at or above the specified value when the allowable time has elapsed, the torque increasing control is forcibly halted.

A multiple-hole tube for heat exchanger, which can be manufactured in a simply way and at a low cost, and a manufacturing method thereof are disclosed. A pair of copper plates 20 with grooves 14 formed in a longer direction by rolling copper plate 11 with a form rolling roller are prepared. A sheet type brazing filler metal is interleaved between bond surfaces, each of which is a surface on the side of grooves 14 of copper plate 20. Copper plates 20 are heat-bonded to each other after both are aligned with respect to the grooves.

An engine speed synchronizer for a manual transmission with an engine clutch, synchronizes rotation of the engine side of the engine clutch with rotation of the transmission side of the engine clutch by engine speed control with reference to operation of a shift lever under condition that the engine clutch is disengaged. The engine speed synchronizer determines whether or not a transmission input speed has started to change in a direction conforming to the operation of the shift lever; permits the synchronization in response to determination that the transmission input speed has started to change in the conforming direction; and inhibits the synchronization in response to determination that the transmission input speed has not started to change in the conforming direction.

A collimator, a radiological imaging apparatus and a nuclear medicine diagnosis apparatus which are able to improve the sensitivity are provided. The radiological imaging apparatus has a collimator 11 disposed to oppose a radiological detection device 12 and having through-holes 11a for passing to the radiological detection device 12 gamma rays in a specified direction out of those radiated from an object to be examined. The collimator 11 is produced by mutually coupling a plurality of metal tubular members 11A each having the through-hole 11a with the help of a bonding agent S in alignment with a plurality of detectors 12a constituting the radiological detection device 12.

A rapid acceleration control apparatus has a rapid acceleration prime mover rotational speed control section and a rapid acceleration start clutch capacity control section. The rapid acceleration prime mover rotational speed control section executes a rapid acceleration start prime mover rotational speed control that control a rotational speed of the prime mover to a target rotational speed required to achieve the rapid acceleration start when a rapid acceleration start condition exists in which both an accelerator and a brake are simultaneously operated while the vehicle is stopped. The rapid acceleration start clutch capacity control section executes a rapid acceleration start clutch capacity control that decreases a connection capacity of the clutch during the rapid acceleration start prime mover rotational speed control executed by the rapid acceleration prime mover rotational speed control section to suppress heating of the clutch due to the rapid acceleration start primer mover rotational speed control.
摘要:
A vehicle control apparatus is configured to avoid a forward lunging of a vehicle during a downshift while decelerating. The vehicle control apparatus has a clutch element that operatively coupled to an output of an engine to perform a gear shift operation and a controller that controls engine speed during shifts. If deceleration fuel cutoff conditions are met immediately after engine speed control accompanying a gear shift, delaying the start of fuel cutoff is prohibited and fuel cutoff is started right away whenever the deceleration operating conditions immediately prior to the start of engine speed control have been sustained for at least a specific length of time. On the other hand, if the deceleration duration is less than the specified time, the start of fuel cutoff is delayed so as to avoid catalyst overheating.

A performance monitor system monitors a number of errors occurring in data processed in a communication apparatus having a duplex configuration formed of two systems. The performance monitor system includes a first unit for monitoring a number of errors occurring in data processed in one of the two systems a second unit for monitoring a number of errors occurring in data processed in another one of the two systems and a control unit for controlling operations of the first and second units. Each of the first and second units has a first counter outputting a first error count value and a second counter outputting a second error count value. The control unit controls the first and second counters so that the sum of the first and second error count values obtained in the first unit is equal to sum of those obtained in the second unit.
