  • Patent number: 11752999
    Abstract: A vehicle control apparatus has a steering wheel 6, an engine 4 for outputting a driving force of a vehicle 1, a brake apparatus 16 capable of applying different braking forces to left and right wheels, and a PCM 14 including a processor and the like. When executing vehicle yaw control, which controls the brake apparatus 16 to apply to the vehicle 1 a yaw moment in the direction opposite to the yaw rate generated in the vehicle 1, after executing vehicle attitude control for reducing an output torque of the engine 4 based on a turning operation of the steering wheel 6, when the control amount of the vehicle attitude control is large, the PCM 14 increases the control amount of the vehicle yaw control compared to when the control amount of the vehicle attitude control is not large.

  • Publication number: 20190193723
    Abstract: The vehicle behavior control device comprised a drive control system 4 and a brake control system 18, wherein a PCM 14 is configured, when steering angle is increasing, to set an additional deceleration to be added to the vehicle, and control the drive control system 4 to attain the additional deceleration, and, when the steering angle is decreasing, to set a yaw moment oriented in a direction opposite to that of a yaw rate being generated in the vehicle, as a target yaw moment to be applied to the vehicle, and control the brake control system 18 to apply the target yaw moment to the vehicle. Particularly, when the steering angle is 0, PCM 14 is configured to set the target yaw moment to 0 so as to terminate the control via the brake control system 18.

  • Patent number: 6030131
    Abstract: A film developing process automatically conveys film to a film developing section. When a cartridge conveyed intermittently by a cartridge conveying device is conveyed to a first stop position, a tapered tongue drawing device is actuated to draw an end portion of a film strip out of the cartridge. At a second stop position, a cutting device and a punching device are operated to cut the tapered tongue and form coupling holes on the end portion of the film strip respectively. At a third stop position, a reinforcing label is applied to the end portion of the film strip by a label sticking device. At fourth and fifth stop positions, the end portions of the film strips are coupled with a leader sheet which has been conveyed and stopped at the other side of the fourth and fifth stop positions. The cartridges are then conveyed together with the leader sheet into the film developing section.

  • Patent number: 5857126
    Abstract: A photosensitive material processing apparatus includes a processing tank and a rack placed in the processing tank. A processing solution is introduced into the interior of the processing tank through the bottom portion of the processing tank. The processing solution introduced from the bottom portion of the processing tank enters a space formed between a bottom turn cover and a bottom turn guide of the rack, and jets from a jetting opening formed in the bottom turn guide toward a transport path for a photosensitive material. Alternatively, the processing solution introduced from the bottom portion of the processing tank enters the space between the bottom turn cover and the bottom turn guide of the rack, passes through a jetting opening formed in the bottom turn guide and a processing solution jetting passage formed in a rack plate, and jets from a jetting opening formed in the rack plate toward the transport path. Accordingly, the processing solution can be agitated effectively.

  • Patent number: 5835811
    Abstract: A photosensitive material processing apparatus including a processing tank and a rack disposed within the processing tank so as to transport a photosensitive material. A pair of rack parts, such as a rack plate and a back plate, which form a side surface of the rack, are joined together to form a duct. Another pair of rack parts, such as a turn guide and a turn cover, which form the bottom portion of the rack, are joined together to form another duct. Slits for jetting a processing solution are provided in a rack part which forms a transport path as well as the duct. Also, a solution exit is provided so as to allow the processing solution to flow out from the transport path to the outside of the rack. The processing tank is provided with a pump and a subtank. Also, a port is provided in the bottom wall of the processing tank to supply the processing solution into the tank.

  • Patent number: 5629751
    Abstract: An automatic photographic developing machine has easily detachable top turn guides each provided with a locking mechanism that allows any incompletely set top turn guide to be pushed to an accurate set position and locked. The top turn guides are detachably mounted between handles provided at tops of racks hung in treating tanks. Each top turn guide has a support piece to be supported on top surfaces of the handles, and a pair of front and rear control pieces. Each control piece has a protrusion. The handles are formed with recesses. Each top turn guide is inserted between a pair of adjacent handles with the control pieces deformed inwardly by gripping them from opposite sides. The control pieces are released with the support piece supported on the top surfaces of the handles to let the protrusions engage in the recesses. The top turn guide is thus locked in position.
