摘要： The present invention relates to holding a call being executed between communication devices in a communication system which has a first function for a holding party of the communication devices to hold the call by transmitting a first request signal to a held party and a second function for the holding party to hold the call by transmitting a second request signal to the held party and receiving a response signal. The holding party transmits the second request signal first and when the response signal is not returned within a given time, transmits the first request signal. A transit device for relaying a call between communication devices, unless detecting the response signal within a given time after relaying the second request signal, transmits the first request signal to the held party, generates the response signal and transmits the generated response signal to the holding party.

摘要： Digital image data corresponding to an original read in by a CCD is stored in a page memory in pixel units, and a CPU reads the stored image data and creates a histogram. For an original having many high-density portions, an image is formed using a LOG conversion table which generates density data that enables reproduction of the tonality of the high-density portions. For an original which is comparatively faint, an image is formed using a LOG conversion table which generates density data that assures tone reproduction up to the maximum density of the original even if high-density portions cannot be reproduced. As a result, tone reproduction suited to the original image can be realized at all times.

摘要： The invention is directed to an arrangement for controlling a braking force applied to each of road wheels of a vehicle depending upon a braking condition, with a hydraulic braking pressure supplied to each of the wheel brake cylinders through an actuator. The actuator is controlled by a braking force controller into which output signals of wheel speed sensors are fed. The hydraulic braking pressure applied to each of the wheel brake cylinders is controlled by the braking force controller in accordance with each wheel speed. And, it is determined whether the vehicle is turning or not. If the vehicle is turning, the hydraulic braking pressure in a wheel brake cylinder operatively connected to one of the rear road wheels positioned at the outer side is controlled such that a decreasing operation of the pressure is restrained for at least a predetermined time period.

摘要： The invention is directed to an arrangement for controlling a braking force applied to each of driven wheels and non-driven wheels depending upon a braking condition, with a hydraulic braking pressure supplied to each of wheel brake cylinders through an actuator. The actuator is controlled by the braking force controller into which output signals of wheel speed sensors are fed. The braking force controller is arranged to control the hydraulic braking pressure supplied to each of the wheel brake cylinders. When one driven wheel is under the anti-skid control, it is determined whether a difference speed between the driven wheels is greater than a predetermined value. If it is determined that the difference speed is greater than the predetermined value, the actuator is actuated to restrain the hydraulic braking pressure from being supplied to the wheel brake cylinder operatively connected to the other driven wheel, e.g., to hold the hydraulic braking pressure supplied to the wheel brake cylinder, or to reduce a rate of increase of the hydraulic braking pressure.
