摘要:
An automatic speed control system for a vehicle includes an automatic transmission, a speed change switch for producing signals for changing a vehicle speed, and a shift down control device. The shift down control device carries out a shift down operation of the automatic transmission of the vehicle under a certain vehicle driving condition when the shift down control device receives the signals from the speed change switch. A gradient detecting device detects a gradient of a running path on which the vehicle is driven, and shift down prohibiting device prohibits the shift down operation even where the speed change switch is actuated to the vehicle speed at least when the gradient of a running path detected is greater than a predetermined value so that unnecessary shift changes are suppressed.

A clutch control apparatus for a mechanical supercharger is used in connection with a mechanical supercharger provided in the intake passage of an engine and driven by the output shaft of the engine through a clutch. The clutch control apparatus suppresses shock during clutch engagement and increases clutch life by controlling the slipping condition of the clutch when the mechanical supercharger is engaged.

A constant-speed cruising control system for a vehicle having an automatic transmission includes a vehicle speed controller which controls the throttle valve of the engine on the basis of the difference between a target vehicle speed and the actual vehicle speed so that the latter approaches the former, a gear shifting mechanism which receives a gear shifting command and shifts the gear stage of the automatic transmission according to the content of the gear shifting command which it receives, and a gear-shifting controller which receives an engine load signal representing the load on the engine and a speed difference signal representing the difference between said target vehicle speed and the actual vehicle speed, and delivers to the gear shifting mechanism a gear shifting command which requires the gear shifting mechanism to shift the gear stage down either when the load on the engine is not lighter than a first preset value or when the load on the engine is lighter than the first preset value and heavier than a second preset value and at the same time the difference between the target vehicle speed and the actual vehicle speed is larger than a preset speed.
摘要:
The engine control system of the present invention comprises an engine output changing device for controlling an engine output of at least one of engine power, engine, engine torque and engine speed. At least two controls for controlling the engine output changing device are selected from a direct control device for directing detecting an actual value to which the engine output changing device is operated. A target value for the engine output changing device is set based on an amount an accelerator is operated to thereby adjust the engine output changing device to eliminate a difference between the actual value and the target value. A vehicle speed control device for detecting an actual vehicle speed, setting a target value of vehicle speed based on the amount the accelerator is operated, and for controlling the engine output changing device, and an acceleration control device for detecting a change in an actual vehicle speed, setting a target value of vehicle acceleration based on the amount the accelerator is operated, and for controlling the engine output changing device, are also provided. A selecting device is used to select one of the direct control, vehicle speed control and acceleration control devices in accordance with a vehicle running condition.

A conveying apparatus has a conveying traveling body traveling below a floor board and supporting a carriage main body by column portions penetrating a slit provided in the floor board. The conveying traveling body is composed of a plurality of trolleys. A load bar couples the trolleys, and a strip cover plate covers the load bar below the slit. The strip cover plate has a length longer than the conveying traveling body and has one end portion in the traveling direction provided with a movable plate portion higher than the other end portion. The movable plate is pivotally supported so as to be swingable upward from a horizontal posture.

In the metal billet to be used for hot dilation forming, a forward side with respect to the pressing direction has a quadrate section and its diagonal length is not more than an inner diameter of a container. Moreover, a backward side with respect to the pressing direction has a circular section and its diameter is substantially same as the inner diameter of the container. The metal billet is heated to a temperature suitable for press working and is set into a container for press forming. While a center of a workpiece of the metal billet is being bored by a boring punch to be operated by a pressing machine, the metal billet is hot-dilated so that a bottomed container for a cask is formed.

摘要:
Corner of each square pipe is molded into a terrace shape having steps. When a basket is constructed by these square pipes, steps of adjoining square pipes are assembled together face to face. Fuel rod aggregates are housed inside the square pipes and in a cells formed between the square pipes. Since the adjoining square pipes are assembled in a staggered arrangement, boundaries of the cells are defined by the walls of the square pipes itself.
