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.

Abstract: A tightening device comprises an upper plate, a lower plate disposed below the upper plate in parallel thereto, a nut rotating gear supported by the lower plate so as to be rotatable in a horizontal plane, and a spur gear provided on an underside of the upper plate and meshable with the nut rotating gear for rotating the nut rotating gear. The upper plate has a portion fittable to a flange of an externally threaded member for preventing the rotation of the threaded member, while the nut rotating gear has a portion fittable to a nut. With the nut manually tightened on the threaded member in advance, the flange fitting portion of the upper plate is fitted to the flange, the nut is fitted in the fitting portion of the nut rotating gear, and the spur gear is thereafter rotated, whereby the nut rotating gear is driven to tighten up the nut on the threaded member.

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.

Abstract: A picture display apparatus has respective modes in which it displays at least three different types of pictures in sequence in response to actuations of a single switch. The picture display apparatus may be incorporated within a conventional television receiver having a programmable timer, and in such case the first type of picture is the normal television picture, the second type of picture is a display of the current day of the week and current time, and the third type of picture is a display of programming information stored in the programmable timer. When the switch is actuated within a predetermined time from the occurrence of a characteristic event in the respective mode, the next type of picture in the sequence is displayed. When the switch is actuated after the predetermined time has elapsed, the first type of picture in the sequence is displayed.

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.
