Abstract: A comparator compares a first data word with a second data word. The comparator includes a first stage of two input XOR gates, each of which receive one bit of the first word and a corresponding bit of the second word, and output a coincidence detection signal. A first inverter circuit receives a control signal and generates an inverted control signal. A decision circuit receives the inverted control signal and each of the coincidence detection signals, and generates a decision circuit output signal which indicates when any one of the coincidence detection signals is active. A two input NAND gate receives the decision circuit output signal and the control signal and generates a comparator output signal. The decision circuit includes an inverter circuit that receives the inverted control signal from the first inverter circuit and a series of transistors connected between the inverter circuit output terminal and ground. The gates of the transistor receive the respective coincidence detection signals.

Abstract: In a power transmitting system, a clutch drive shaft driven through bevel gears and by an input shaft is laterally extensive and left and right electromagnetic clutches are disposed between opposite ends of the clutch drive shaft and left and right output shafts, respectively. A clutch body heated during the transmission of a power is disposed at a laterally outer location of the system to provide enhanced heat-radiatability, and an annular solenoid is disposed inside the clutch body. A bearing for supporting each of the opposite ends of the clutch drive shaft is disposed radially inside the solenoid. Thus, the lateral dimension of the power transmitting system is reduced.

Abstract: A left hydraulic pump connected to a left wheel and a right hydraulic pump connected to a right wheel of a vehicle are connected by a first oil passage and a second oil passage to constitute a closed circuit, and first and second variable throttle valves are provided between the first and second oil passages and the tank. Either one of the first and second variable throttle valves is throttled to cause the first and second hydraulic pumps to produce a braking force and a driving force, respectively, thereby controlling a yaw moment. At the same time, when either one of left and right wheel suspensions expands, the roll rigidity of the vehicle increases or decreases to vary the cornering forces of the wheels, thereby producing a yaw moment which assists in the yaw moment produced by the first and second hydraulic pumps.

Abstract: High quality bisphenol A is produced from a neutral crystalline adduct of bisphenol A and phenol by fusing the adduct in an atmosphere having a maximum oxygen content of 0.005% by volume, followed by evaporation of liberated phenol. The crystalline adduct may be mixed with an aliphatic carboxylic acid before the fusion to reduce the coloring of the product. When an acidic crystalline adduct is used, the use of a strong alkali salt of an aliphatic carboxylic acid is suitably used. Interior surfaces of the apparatuses for carrying out the fusion and evaporation are desirably washed with an organic solvent to remove oxygen therefrom. The evaporation of phenol is suitably performed by two stage steam stripping wherein a used stripping gas obtained in the second stage is employed as a stripping gas in the first stage while steam is used as the stripping gas in the second stage.
