  • Patent number: 4807497
    Abstract: In a system for integrally controlling an automatic transmission and an engine, having a pattern select switch, and wherein engine torque is changed by a predetermined change value to thereby maintain the satisfactory shift characteristics, at least one of an engine torque change performing region and an engine torque change value is corrected in accordance with the state of the pattern select switch. As a result, the optimal engine torque change during shifting can be constantly performed regardless of the operator-selected shift pattern.

  • Patent number: 4807179
    Abstract: A method and apparatus are provided for data storage in, for example, a black box for an aircraft. A static digital memory is divided into three portions, A, B and C. Data is read into successive sequential portions of wrap-around memory portion A. When an interrupt signal is received, e.g., due to a crash, the memory part A address to which the last data was input is entered into memory part B, along with an indication of which parameter was entered at that address. Data then is stored in sequential portions of memory part C until the end thereof is reached. To read the data, the last address to which data was entered in part A is read from memory part B, data is read from the position immediately following that entry to the end of part A, then from the beginning of part A through to the last entry. Data then is read from memory part C. The resultant data represents a period of time from shortly before, e.g., 0.3 ms, to some time, e.g., a couple of seconds, after the interrupt signal.

  • Patent number: 4806025
    Abstract: Automatic self-aligning ball metals rotatably mounted at both end parts of a rotor shaft in an electric motor are supported by holding devices. The holding device is designed in the form of a disc having a flange portion around the outer periphery thereof. It is formed with a plurality of pawls having different intensities of resilient force which extend in the radial direction from an area located in the proximity of the flange portion. The pawls having a higher intensity of resilient force and the pawls having a lower intensity of resilient force are alternately arranged in the peripheral direction of the holding device and the inner part of each of the pawls is bent at a certain inclination angle. The pawls having a lower intensity of resilient force are adapted to come in contact with the metal ball earlier than the pawls having a higher intensity of resilient force. Each of the pawls having a higher intensity of resilient force has a width wider than the pawls having a lower intensity of resilient force.

  • Patent number: 4807285
    Abstract: An in-band television signal scrambling method and apparatus are disclosed which employ a scrambler which receives and scrambles a television signal by suppressing the amplitude of the horizontal synchronizing signals contained therein to a point below the "black" level and which generates whiter-than-white timing pulses in the scrambled television signal for use by a descrambler in reconstructing the suppressed amplitude horizontal synchronizing signals, and one or more descramblers for detecting the whiter-than-white timing pulses in the scrambled television signal and generating therefrom switching signals for a switchable attenuator through which the scrambled television signal passes. The attenuator boosts the amplitude of the suppressed amplitude horizontal synchronizing signals relative to the remainder of the scrambled television signal, thereby restoring the scrambled television signal to an unscrambled condition.

  • Patent number: 4805768
    Abstract: A paper container filling a liquid content which comprises an upper air gap formed therein for sealing solely carbon dioxide or nitrogen gas and carbon dioxide. Thus, a recess is produced on the paper container by utilizing a small pressure reduction in the container generated as a result of carbon dioxide dissolved in the liquid content, and the recess is used as a criterion of deciding the presence of gas substitution, presence of pinhole of the container and the propriety of sealing of the container only by the recess. This container can be fully inspected by the naked eye. Further, a method of filling gas and apparatus for filling the gas in a composite paper container including aluminum foil or polyethylene by eliminating the abovementioned disadvantages and performing gas substitution merely by adding a simple unit on a filling machine, thereby holding taste, odor and nutrient components of the container contents for 4 or longer months.
