Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
213 words
A television receiver comprising: a computing means for performing a computing operation on input data provided by an input means such as a keyboard; a register having 4 X n bits as a memory means, where n is the number of digits, for storing the data in operation from the uppermost digit; a means for generating four clock pulses every time it counts 4 X (n-1) clock signals synchronized with a clock pulse of the computing means; a means for writing the data obtained from the computing means starting from the lowermost digit thereof into said register with a means for generating drive pulses in response to said clock pulses; a means for reading out the contents of said register from the uppermost digit by applying drive pulses which are generated by means of synchronizing signals included in the television broadcasting signals, after writing the data in said computing means into said register; a means for generating a character signal by converting the signal read out of said register into the character signal; a means for receiving a television broadcasting signal and demodulating the picture signal; and a picture tube for displaying thereon an image in response to the application of said character signal or both of the character and the picture signals.
Claim 2
Dependent Claim
213 words
A television receiver comprising: a computing means for performing a computing operation on input data provided by an input means such as a keyboard; a register having 4 X n bits as a memory means, where n is the number of digits, for storing the data in operation from the uppermost digit; a means for generating four clock pulses every time it counts 4 X (n-1) clock signals synchronized with a clock pulse of the computing means; a means for writing the data obtained from the computing means starting from the lowermost digit thereof into said register with a means for generating drive pulses in response to said clock pulses; a means for reading out the contents of said register from the uppermost digit by applying drive pulses which are generated by means of synchronizing signals included in the television broadcasting signals, after writing the data in said computing means into said register; a means for generating a character signal by converting the signal read out of said register into the character signal; a means for receiving a television broadcasting signal and demodulating the picture signal; and a picture tube for displaying thereon an image in response to the application of said character signal or both of the character and the picture signals.
Claim 3
Dependent Claim
65 words
A television receiver according to claim 1, wherein there is provided a means for counting pulses of the horizontal sync signal involved in the television signal and wherein the numerals representing the process of computation are arranged on said picture tube with an appropriate space left therebetween by reading out of said memory means the stored information when the counted value reaches a predetermined one.
Claim 4
Dependent Claim
60 words
A television receiver according to claim 1, further comprising at least three registers each having 4 X n bits to constitute said memory means, the computing information being selectively applied respectively to said registers to store therein the operands and the computed result, and the computing process being displayed on said picture tube by reading the contents of said registers.
Claim 5
Dependent Claim
60 words
A television receiver according to claim 3, wherein there is provided a means for counting the pulses of the horizontal sync signal involved in a television signal and a means for generating a line signal when the counted value reaches a predetermined one, so that a line is displayed between said operands and said computed result on said picture tube.
Claim 6
Dependent Claim
81 words
A television receiver according to claim 1, wherein there is provided a means for counting each number by three digits from the lowermost digit upward when the number is read out of said memory means and a means for gating a driving pulse applied to said memory means for the purpose of reading in response to the output of said counting means, so that spaces are provided between every third and fourth digits of each number displayed on said picture tube.
Claim 7
Dependent Claim
41 words
A television receiver according to claim 1, wherein said picture tube is a color picture tube and a means is further provided for displaying the computing process in some colors and in a plurality of rows on said color picture tube.
Claim 8
Dependent Claim
48 words
A television receiver according to claim 3, wherein four registers for storing therein the memory value, the operand, the operator and operand, and the computed result and the stored information being then read out to be displayed in four rows in the order mentioned on said picture tube.
