  • Patent number: 11932118
    Abstract: The electric vehicle according to the present disclosure calculates motor torque using an MT vehicle model simulating an MT vehicle having a manual transmission and an internal combustion engine. In the first operation mode, an operation amount of a pseudo-clutch pedal and a shift position of a pseudo-gearshift are input to the MT vehicle model to reflect operation of the pseudo-clutch pedal and operation of the pseudo-gearshift in electric motor control. In the second operation mode where the operation of the pseudo-clutch pedal is not needed, an operation amount of a clutch pedal calculated by a driver model is input to the MT vehicle model instead of the operation amount of the pseudo-clutch pedal.

  • Patent number: 5841317
    Abstract: A differential amplifier achieving a high throughput rate with reduced power consumption includes a differential circuit, output circuit, a constant current source transistor, a drive transistor, and a switching circuit. A difference voltage relative to a difference between voltages applied to non-inverting and inverting inputs of the differential circuit is applied to the switching circuit. The switching circuit supplies a drive signal to the drive transistor to enable the drive transistor when the difference voltage is below a predetermined threshold voltage, and to disable the drive transistor when the difference voltage is above the predetermined threshold voltage.

  • Patent number: 5648791
    Abstract: A liquid crystal display control system comprises a liquid crystal panel, a plurality of data latches for storing digital gray scale data, and a plurality of D/A converters for converting the outputs of the data latches into analog signals to be applied to the liquid crystal panel. The display data is digital signals, and the digital signals are processed up to the D/A converters just before the liquid crystal panel. Afterwards, the digital signals are converted into analog signals in the horizontal display period of relatively slow operating speed, and therefore analog circuits having many adjusting points may be reduced. Accordingly, the adjusting positions are reduced, and the adjusting process in mass production is simplified. In the case of a large screen display, in particular, although the data transfer speed is high, since the display data are digital signals, a high display quality is obtained by transferring the signals without deteriorating the display data.

  • Patent number: 4771663
    Abstract: To eliminate defects such as burr, rollover, sags, scar, etc. from cut-off surfaces of a workpiece in a turret punch press, for instance, a novel height-different punch formed with a lower front edge, an upper rear edge, and an intermediate edge extending between the two edges is used for the punch press. While feeding the workpiece on a horizontal plane in a predetermined direction, the punch is struck by a striker at a first stroke so that the lower front edge thereof cuts off the workpiece partially in cooperation with a die; at the succeeding strokes so that the intermediate edge thereof cuts off the workpiece mincingly and curls refuse within a recess of the die; and at the last stroke so that the upper rear edge thereof cuts curled refuse away from the workpiece to complete a multistroke punching operation.

  • Patent number: 4378003
    Abstract: An internal combustion engine having first valve means disposed in the exhaust system and adapted to impart a resistance to the flow of exhaust gas to control the flow rate of the latter, and second valve means provided in the intake passage of said engine and adapted to introduce fresh air to the intake passage when r.p.m. of the engine has reached a predetermined value. During operation of the engine, a part of the exhaust gas is made to return into the combustion chamber due to the resistance imparted by the first valve means, and the unburned hydrocarbons in the exhaust gas returned to the combustion chamber are efficiently burned by the presence of fresh air which is introduced through the second valve means. Thus an improved internal combustion engine which can operate at a much improved fuel economy and which can minimize the emission of unburned hydrocarbons to the atmosphere is obtained.
