Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 120 words
A display device for a transceiver and the like comprising: a phase-locked loop, a pulse generating section, a phase-locked loop control section for channel selecting connected to said phase-locked loop, a time-counting section for time-counting connected to said pulse-generating section, a change-over circuit connected to the phase-locked loop control section and to the time-counting section for selectively transmitting channel selecting signals received from said phase-locked loop control section and time counting signals received from said time-counting section, an electronic display section connected to said change-over circuit and responsive to the channel selecting and the time-counting signals transmitted therefrom for selectively carrying out channel display and time display; and a change-over switch for controlling the switching operation of said change-over circuit.
Claim 2
Dependent Claim 120 words
A display device for a transceiver and the like comprising: a phase-locked loop, a pulse generating section, a phase-locked loop control section for channel selecting connected to said phase-locked loop, a time-counting section for time-counting connected to said pulse-generating section, a change-over circuit connected to the phase-locked loop control section and to the time-counting section for selectively transmitting channel selecting signals received from said phase-locked loop control section and time counting signals received from said time-counting section, an electronic display section connected to said change-over circuit and responsive to the channel selecting and the time-counting signals transmitted therefrom for selectively carrying out channel display and time display; and a change-over switch for controlling the switching operation of said change-over circuit.
Claim 3
Dependent Claim 34 words
A display device for a transceiver and the like as set forth in claim 1, wherein said pulse-generating section is a reference oscillator which is connected to said time-counting section through a frequency divider.
Claim 4
Dependent Claim 36 words
A display device for a transceiver and the like as set forth in claim 1, wherein said pulse-generating section is an independent crystal oscillator which is connected to said time-counting section through an oscillatory frequency divider.
Claim 5
Dependent Claim 34 words
A display device for a transceiver and the like as set forth in claim 1, wherein said pulse-generating section is a commercial power supply which is connected to said time-counting section through a converter.
Claim 6
Dependent Claim 56 words
A display device for a transceiver and the like as set forth in claim 1, wherein said time-counting section is adapted to be selectively connected to a reference oscillator in said phase-locked loop through a frequency divider, to an independent crystal oscillator through an oscillatory frequency divider, and to a commercial power supply through a converter.
Claim 7
Dependent Claim 134 words
A display device for use in a transceiver or the like comprising: a phase-locked loop equipped with a reference oscillator, a phase-locked loop control section for channel selecting connected to said phase-locked loop, a frequency divider connected to said reference oscillator, a time counting section connected to said frequency divider, a switching circuit connected to said phase-locked loop control section and said time counting section for selectively transmitting channel selecting signals received from said phase-locked loop control section and time counting signals received from said time counting section, a change-over switch connected to said switching circuit, and an electronic digital display section for selectively carrying out channel display and time display, said digital display section being connected to said switching circuit and responsive to the channel selecting and the time counting signals transmitted therefrom.
Claim 8
Dependent Claim 134 words
A display device for use in a transceiver or the like comprising: a phase-locked loop equipped with a reference oscillator, a phase-locked loop control section for channel selecting connected to said phase-locked loop, a frequency divider connected to said reference oscillator, a time counting section connected to said frequency divider, a switching circuit connected to said phase-locked loop control section and said time counting section for selectively transmitting channel selecting signals received from said phase-locked loop control section and time counting signals received from said time counting section, a change-over switch connected to said switching circuit, and an electronic digital display section for selectively carrying out channel display and time display, said digital display section being connected to said switching circuit and responsive to the channel selecting and the time counting signals transmitted therefrom.
