Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
136 words
A cooking apparatus comprising: setting position means, including a variable resistor, for establishing a variable desired value based on a setting position thereof and producing an variable output signal corresponding to said desired valve when said setting position is within a predetermined range, and producing an output signal representing no desired valve when said setting position is outside said predetermined range; timer means for counting until achieving a value indicated by said output signal of said setting position means; means for detecting whether said timer means is operative based on said output of said setting position means; means for cooking until said timer means counts to said desired value; and means for continuing said cooking indefinitely if said timer means is rendered inoperative by said output signal representing no desired value, before reaching said desired value.
Claim 2
Dependent Claim
136 words
A cooking apparatus comprising: setting position means, including a variable resistor, for establishing a variable desired value based on a setting position thereof and producing an variable output signal corresponding to said desired valve when said setting position is within a predetermined range, and producing an output signal representing no desired valve when said setting position is outside said predetermined range; timer means for counting until achieving a value indicated by said output signal of said setting position means; means for detecting whether said timer means is operative based on said output of said setting position means; means for cooking until said timer means counts to said desired value; and means for continuing said cooking indefinitely if said timer means is rendered inoperative by said output signal representing no desired value, before reaching said desired value.
Claim 3
Dependent Claim
15 words
The cooking apparatus according to claim 1, wherein said output signal is an analog signal.
Claim 4
Dependent Claim
23 words
The cooking apparatus according to claim 2 further including means for converting said output signal from an analog signal to a digital signal.
Claim 5
Dependent Claim
25 words
The cooking apparatus according to claim 3 further including means for entering a desired value data based on said variable output-signal into said timer means.
Claim 6
Dependent Claim
19 words
The cooking apparatus according to claim 4, wherein said timer means includes means for downcounting said desired value data.
Claim 7
Dependent Claim
35 words
The cooking apparatus according to claim 5, further including means for sensing the presence of an object to be heated, said timer means commencing downcounting when said sensing means senses the presence of the object.
Claim 8
Dependent Claim
24 words
The cooking apparatus according to claim 6, further including means for displaying said desired value data and remaining value data with progress of downcounting.
