摘要： There is provided a control system for an internal combustion engine. An amount of variation in the rotational speed of the engine is detected. A rotational speed variation reference value is calculated based on an averaged value of the detected amount of variation in the rotational speed of the engine. The detected amount of variation in the rotational speed of the engine is compared with the rotational speed variation reference value. The amount of fuel to be supplied to the engine is corrected based on results of the comparison.

摘要： A battery container is provided with a battery cover having side walls so that a gap is formed between the side walls of the container and the side walls of the cover. The upper end portion of a bottomed heat-shielding case is inserted into this gap so that the heat-shielding case is detachably attached to the battery container and covers the container and forms a space between the container and the case. The space between the container and case is closed to air outside the case and air convection between the outside air and the air inside the space can be prevented thereby increasing the heat-shielding effect for protecting the storage battery from high temperatures. Additionally, the heat-shielding case is designed to be attached securely to the battery container (1) to make one body therewith, making it easier to mount and dismount them in an automobile engine compartment.

摘要： A VTR incorporating a video printing controller comprising at least one rotary magnetic head for scanning recording tracks formed on a magnetic tape to reproduce a video signal recorded on a recording track specified by a marker signal, a marker signal detector for detecting the marker signal specifying the recording track carrying the video signal to be printed, and a system controller connected to the marker signal detector and to a video printer connected to the VTR. The system controller gives a video printer control signal to the video printer upon receipt of a marker signal detection signal from the marker signal detector to control the video printer for printing out in a hard copy the video image reproduced from the recording track specified by the marker signal. Thus, the recording track storing the video image desired to be printed is located automatically by searching the recording tracks for the marker signal, and then the desired video signal is printed out automatically.

摘要： In a helical scan apparatus having a rotary head or heads for recording and/or reproducing video and audio signals in oblique tracks on a magnetic tape with the recorded audio signals being recorded in overscan areas of the oblique tracks and with the pitch of the tracks being different as a result of changes in the tape speed for different recording modes; index signals are recorded by the rotary head or heads at predetermined positions in the overscan areas of a plurality of the oblique tracks for a period of time dependent upon the recording mode previously used for recording the video and audio signals. Therefore, in a program search operation employing high speed playback, the index signals can be extracted from the output of the rotary head or heads for identifying a respective program or event irrespective of the recording mode with which the video and audio signals were recorded.
