  • Patent number: 5719619
    Abstract: A bidirectional broadcasting method and system allows, even when an existing telephone voting service is used to respond to a bidirectional broadcast, broadcasting wherein a plurality of questions are related to each other. A broadcasting station broadcasts questions, answer choices for a response to each question and responding destination telephone numbers for the individual answer choices, and successively broadcasts evaluation information for allowing receiver apparatus to perform evaluation of histories of responses to the questions and determine whether or not the responding persons of the individual receiver apparatus are response allowed persons. Each receiver apparatus stores the history of responses to the questions into a memory and, based on the evaluation data from the broadcasting station, evaluates the history of responses to the questions.

  • Patent number: 5502883
    Abstract: A reference range of tightening torques is predetermined relative to the rotation angle of a threaded member as normally tightened. In tightening up a nut on an externally threaded member, the tightening torque is detected by a torque sensor every time the nut is rotated through a specified angle, and whether the tightening torque relative to the rotation angle is within the reference range is judged by a microcomputer. The result of judgment is indicated by a light-emitting diode and a buzzer.

  • Patent number: 4527204
    Abstract: A single, hand held remote control unit produces command signals used to control all operational aspects of a video tape recorder and an associated television receiver, and the video tape recorder and television receiver include switches that upon actuation can provide various interconnections so that all operating modes of the two units are possible. Actuation of the switches is performed by controllers, arranged at the particular units, and which receive the coded command signals from the remote control unit to set the switches in accordance with any of several keys that can be actuated on the remote control unit. In one aspect, depressing a single playback key at the remote control unit will produce coded signals received by the controllers to set the television receiver to an unused channel frequency and cause the video tape recorder to reproduce a prerecorded video tape, with the reproduced signal fed to the television receiver over that unused channel for display.
