Filed: 1991-02-08
Abstract: PURPOSE:To perform proper control even during fail of a car body slip angle detecting means, in a device to control the slip ratios of front and rear wheels based on a detecting result from the car body slip angle detecting means. CONSTITUTION:During normal operation of longitudinal speed sensor to detect a car body slip angle and a lateral speed sensor, the target slip ratios of front and rear wheels are decided at S303-S306 according to the slip angle of each wheel, but during fail, the target slip ratios are set to respective preset specified values. Especially, a front wheel slip ratio during non-brake is set at S301 to zero, and wheel torque control of front wheels is prohibited. Regarding front wheels and rear wheels during brake and rear wheels during non-brake, target slip ratios are set at S308, S309, and S311 to respective different specified values. During normal operation of a sensor, vehicle running stability is further improved than that of a conventional type, and during fail of a sensor, antiskid control and traction control are practicable as usual.

Title: Radio communication equipment
Inventor: IRINO ETSURO
IPC: H04B7/00
Filed: 1986-02-25
Abstract: PURPOSE:To evade such a case where the noise is heard at the receiver side immediately after the transmission radio wave is cut off, by extending the period of transmission signal than the period of transmission signal together with the out-of-voice band tone superposed on the transmission signal just for said period of transmission signal at the transmitter side and at the same time cutting off the voices at the receiver side after detecting said tone. CONSTITUTION:The transmitter start input A is turned off when the transmission is stopped. However, the transmission radio waves are sent for a fixed period even after the period of the input A by a transmission break delay switch part 9. While the switch of an out-of-voice band tone switch part 10 is opened immediately after the period of the input A. Thus the out-of-band tone is not superposed on the transmission radio wave. This break or said tone is detected by an out-of-band tone detecting part 12 at the receiver side. Then the switch of a reception voice switch part 6 is opened. Thus no noise is heard through a speaker at the receiver side even immediately after the period of transmission signal.

Title: Telephone set-loudspeaking type interphone system
Inventor: MORI HIDEYASU
IPC: H04M1/00
Filed: 1986-02-25
Abstract: PURPOSE:To attain a stable calling by reducing the balance resistance of the hybrid circuit of a bidirectional amplifier with the AND output of the detection output of the direct current conducting to two telephones and keeping the balance of said hybrid circuit when two telephone sets are connected in parallel with each other. CONSTITUTION:Both telephone sets A and B switch the channel selection switches S1-S4 to the 13-14 side and at the same time have the relay connection to a loudspeaking type interphone system C in order to attain a call among three persons. Under such conditions, the direct current is conducted to both resistances 16 and 17 when the handsets of both telephones A and B are hooked off. Thus the logic levels of both detection voltage outputs 7 and 8 are set at 'H' together with the output of an AND circuit G also set at 'H'. As a result, an analog switch transistor TR3 is turned on and a resistance R19 is connected in parallel to a resistance R2. Then the parallel resistance value is halved if the resistance value of the R19 is set equal to that of the R2. Thus the same rate is attained as that of the impedance reduction caused when both telephone sets A and B are connected in parallel.

Filed: 1979-04-04
Abstract: PURPOSE:To heighten stability, by providing an output transformer with a tertiary winding to generate a first feedback signal to a switching section and providing a compensation circuit which detects an input current to the switching section to generate a second feedback signal thereto. CONSTITUTION:In a stationary state, an output voltage across the secondary winding 17b is stabilized at a set value.
