Abstract: The tampering work can be easily detected by using the seal for sealing of a drink/food container. By providing an unseal confirmation member of which the condition changes when adhesive seal member 8A, 46A of seal for sealing 8, 46 provided on the drink/food container 1, 40 is reattached after being peeled once, the user can confirm at first sight that the drink/food container has been used.

Abstract: A modulator converts an inputted data to be transmitted into a septenary data, modulates a carrier by the converted data, and transmits the modulated carrier via an antenna. A demodulator demodulates a received data supplied from the antenna into an octonary data, which is converted into a septenary data. According to the structure, a vector representing the modulated carrier is prevented from passing a “O” point when a phase shift of the modulate carrier occurs.

Abstract: According to this invention, in a device for supplying wrap film, by drawing out a wrap film from a wrap film container and cutting off, a user makes a sheetlike wrap film guide that has the property of adhering to the wrap film is adhered to the end part of the wrap film, and drawing out them in one body almost over the width. Thus the user can further easily, hygienically and safely cut the wrap film.

Abstract: A mobile radio system provides an appropriate usage environment in accordance with how often a mobile station is used. The base station informs via a broadcast channel each of the mobile station of PCHs and corresponding intermittent reception intervals. The mobile station selects one of the PCHs having a user's desired intermittent reception interval, and reports the selected PCH to the base station. The base station pages the mobile station over the PCH reported by the mobile station.

Abstract: A pull top type can with a seal is provided, which is sanitary, can prevent injury of the user, can prevent spattering of the contents and can be re-used. The seal (5, 5A) is attached to the pull top type can (1, 1A) such as to cover the tap.

Abstract: In a cellular communication system, a mobile station detects field intensities of surrounding cell sites and transmits a report signal to one of the surrounding cell sites having highest field intensity. Each cell site detects the channel occupancy of its speech channels in response to a connection request from a home cell site and returns a response indicating whether the request is to be granted or not depending on the channel occupancy. The home cell site is responsive to the report signal for assigning priorities to the surrounding cell sites according to its channel occupancy and selects one of the surrounding cell sites according to the assigned priorities. If the home cell site is not selected, it sends a connection request to the selected cell site for receiving a response. If it is selected, it determines whether a speech channel is available or not depending on its channel occupancy.

Abstract: In a pager receiver for receiving first through N-th pager signals successively at a first predetermined period (T1) and comprising a battery saving switch and a receiving circuit connected to the switch and enabled while the switch is in an on state, a controller puts the switch in the on state repeatedly at a second predetermined period (T2) to make the receiving circuit receive at least a portion of a preamble signal (PA) and whole of a synchronization (SS) and an address (AS) signals of the first pager signal (RS1) and detect an address signal end of the first pager signal. The controller keeps the switch in the on state to make the receiving circuit receive at least a part of the preamble signal and whole of the synchronization and the address signals of each of the second (RS2) through the N-th pager signals and detect the address signal end of each of the second through the N-th pager signals.

Abstract: A vehicle radio telephone system is constructed to talk between a vehicle and a fixed station through any one of a plurality of radio channels. Upon degradation of a talking condition during talking, the radio channel is switched and a tone is sent to talkers to inform them that the radio channel is now being changed.

Abstract: A mobile communication system is disclosed having a plurality of base stations controllable from a single control station to transmit control signals from said control station to respective geographic zones. Fault detecting means capable of detecting transmission lapses, waveform irregularities, or phase irregularities, is provided in each base station for cutting off transmission when a fault is detected.

Abstract: A mobile radio communication system utilizes message channels of the same frequencies in separate geographic zones. Also, zones utilizing the same message channels are assigned distinguishing control codes which are transmitted with control signals to prevent control signals related to one zone from interfering with communications with another zone using the same message frequencies.
