Abstract: A motor torque control system has an inverter for converting a DC voltage from a battery into an AC voltage to energize an AC motor based on a command amplitude value. An input electric power calculating unit calculates an input electric power supplied from the battery based on a current and a voltage from the battery. A target electric power calculating unit calculates a target electric power to be supplied to the AC motor based on the rotational speed of the AC motor and a command torque value indicative of a torque to be produced by the AC motor. A PI control unit produces a control signal from the difference between the input electric power and the target electric power, and a PWM control unit controls the command amplitude value based on the control signal.

Abstract: Oral antibacterial compositions contain a penem or carbapenem antibiotic in combination with an absorption improver selected from substances capable of inhibiting the dipeptidase localized on/in epithelial cells of the small intestine, cilastatin, glutathione and N-acetyl-L-cysteine. Gastrointestinal absorption of the penem or carbapenem antibiotic can be improved by orally administering the absorption improver in combination with the antibiotic.

Abstract: A synchronous motor control system controls a synchronous motor on an electric vehicle for propelling the electric vehicle in a propulsive mode or regenerating electric energy in a regenerative model. The synchronous motor control system has a rotational speed sensor for detecting a rotational speed of the synchronous motor, an accelerator for producing a torque command signal, and a driver connected between a battery on the electric vehicle and the synchronous motor for operating the synchronous motor in either the propulsive mode or the regenerative mode. A controller is responsive to the rotational speed detected by the rotational speed sensor and the torque command signal produced by the accelerator for controlling the driver to operate the synchronous motor in either the propulsive mode or the regenerative mode.

Abstract: A false-creep generator device for an electric vehicle equipped with a transmission controls an electric motor to cause the electric vehicle to creep when the accelerator pedal of the electric vehicle is not depressed, no brake is applied to the electric vehicle, the transmission is in a drive or reverse position, and the speed of travel of the electric vehicle is lower than a predetermined creep speed.

Abstract: In a magnetic head of the metal-in-gap type, a magnetic metal layer provided in a magnetic gap comprises a plurality of thin film layers. Of the thin film layers, one which is located on the side of the magnetic gap is formed by use of a material having a comparatively higher saturation magnetic flux density whereas one which is located on the side of facing the magnetic core is formed by use of a material having a comparatively lower saturation magnetic flux density. Magnetic recording efficiency can be thereby enhanced, without a considerable increase in the thickness of the magnetic metal layer provided in the magnetic gap.
