Abstract: There is proved a driving force control system which comprises device for measuring operating state of the vehicle brake system and generating an output signal, and device for controlling a driving force upon a predetermined condition being fulfilled after the output signal has indicated a predetermined operating state of the vehicle brake system.

Abstract: A structure for mounting a vibratory body on a support includes an elongated mounting member having an elasticity. The mounting member is resiliently connected to the support and also to the vibratory body. The connection of the mounting member to the support is located at a position at which the phase of bounce-mode vibrations of the mounting member is opposite in sign to that of two-node-mode transverse vibrations of the mounting member.

Abstract: An electromagnetic flow meter comprising an electromagnetic flow signal generator having a pipe through which a fluid to be measured flows, an exciting coil and a pair of electrodes, an exciting circuit for supplying an exciting current whose normal value is switched at a low frequency to the exciting coil of the generator, and a signal processing circuit for effecting an arithmetic operation and outputting a flow rate signal concerning the flow rate of the fluid based on voltages induced between the electrodes of the generator; wherein to keep constant the exciting current, the exciting circuit comprises a switching regulator for stabilizing a power supply voltage and producing an exciting DC voltage dependent on a voltage setting, a switching circuit connected between the exciting coil and the switching regulator and applying the exciting voltage, while turning ON and OFF at a low frequency, to the exciting coil and an exciting current detection means connected in series between the switching regulator and

Abstract: A programmable controller is provided with a controller body including a microprocessor having a ROM for storing user programs connected with a socket thereto. A programmer which is connected by a connector to a data bus or the controller body has a means to switch to a program mode to write a user program in a RAM by operating keys, and a test run mode to execute the user program written in RAM on the controller body, and a means to copy the user program written in RAM of the programmer to said ROM. The user program stored in ROM which is inserted in said socket is executed when the programmer is isolated from the controller body.
