Title: Device for warning rotting of food in rerefreshing chamber of refrigerator
Inventor: JEONG HAK JAE
IPC: F25D25/00
Filed: 1998-12-24
Abstract: PURPOSE: A device for warning rotting of a received food in a refreshing chamber of a refrigerator is provided to inform a user of the rotting by sensing ammonia generating from the received food due to rotting. CONSTITUTION: When a food received in a refreshing chamber(24) is a fish or a shellfish, a user operates a key of fish and shellfish of a key operation panel part(32). If a food received in the refreshing chamber is meat, the user operates a meat key of the key operation panel part. A control part(36) radiates a blue LED(light emitting diode) which is a second emission part(34) according to the key operation of the key operation panel part. If a user forgets the time for use of the received food or opens the refreshing chamber frequently, the temperature in the refreshing chamber rises and the food received in the refreshing chamber starts to be rotten. The aging of the received food is progressed at high speed and ammonia gas is generated from the received food. Herein, a pH sensing sensor(26) senses the ammonia gas and transmits the sensed data to the control part. The control part compares the input ammonia gas value to a predetermined ammonia gas data value and outputs a warning signal to a red LED which is a first emission part(28) if the compared value is over a certain reference value.

Abstract: PURPOSE: A method for processing Hangul(Korean character) using telephone buttons is provided to arrange Korean alphabets(Hangul) on the telephone buttons, so as to reduce overlapped Korean alphabets and to minimize the number of times for inputting Hangul. CONSTITUTION: A telephone for inputting Hangul(Korean character) reads inputted button data to separate an initial consonant in a Korean orthographic syllable. The telephone reads next inputted button data to decide whether the data presents a numerical button of a first line. If so, the telephone senses the number of times of inputted numerical buttons, and decides whether consonants are inputted. If so, the inputted button data is processed as a final consonant. If the consonants are not inputted, the inputted button data is processed as a vowel or a semivowel of the Korean syllable, and a vowel/semivowel check flag is set up as '1'. If the inputted button data is not a button in the first line, the telephone decides whether the vowel/semivowel check flag is set up as '1'. If so, the inputted button data is processed as a final consonant. If the flag is not set up as '1', the data is processed as a vowel/semivowel, then the flag is set up as '1'. The steps from the step of reading the inputted button data to the step of setting up the flag as '1', when the flag is not set up as '1', are repeatedly performed. The processed initial consonant/the vowel or semivowel/the final consonant are synthesized to input one character.

Abstract: PURPOSE: A method for performing an exposure process in a stepper equipment is provided to save time taken for automatic correction by the equipment, by immediately informing an operator of an error when the exposure process is far beyond a normal setting condition. CONSTITUTION: A difference between a planed image by a predetermined condition and an image obtained from a real equipment is measured to obtain a varied value from the predetermined condition. The varied value is compared with a previously-inputted scope necessary for correction. The varied value is automatically reflected on a setting condition of equipment according to the comparison result, and an image quality control for performing a correction of the equipment is carried out. An exposure process is carried out regarding a process wafer of the equipment. If the varied value falls within the scope necessary for the correction, the varied value is reflected to perform a correction of the equipment by the setting condition, and the exposure process is performed. If the varied value is beyond the scope necessary for the correction, the equipment is stopped to ask an operator of whether the exposure process is carried out regarding the process wafer.
