IPC: D06F79/02
Filed: 1987-12-11
Abstract: PURPOSE: To provide a safe cordless iron without causing excessive temperature rising by stopping supplying power to a heater when the interval of temperature signal pulses from the temperature detecting circuit of an iron main body part is longer than second specified time or when there is no temperature signal pulse. CONSTITUTION: The temperature of a base 11 of the iron body part 13 is detected by a thermosensitive element 16 and the temperature signal pulses of the interval corresponding to the temperature at that time are generated from a temperature detecting circuit 17. The signal is transmitted to a signal detecting circuit 18 and next, a temperature control circuit 19 counts the interval of pulses inputted from the circuit 18 and compares it with first specified time. When the base temperature is discriminated lower than a set value, power is supplied to a heater 12 but when the base temperature is discriminated higher, power supply to the heater 12 is stopped. Thus, the temperature of the base 11 is kept at a prescribed value. Besides, when the pulse from the circuit 18 shows the interval exceeding the second specified time or when there is no pulse signal longer than the second specified time, the circuit 19 discriminates abnormality and stops supplying power to the heater 12.

Filed: 1990-11-20
Abstract: PURPOSE:To prevent the misdeletion, etc., of the undesired programs by deleting these programs after recognizing accurately the working situation and deciding automatically the necessity or nunecessity of programs. CONSTITUTION:A designated parameter generator 22 retrieves a program file device/job control file device control file 21 and acquires the information on the names of programs and a storing file for the production of a correspondence table. Then the producer 22 retrieves the updating history information on a program file based on the file 21. Then the program and file names are collated with the table. When these names are present in the table, the next program is collated. If not, the final updating data is checked. When a program is not updated for a fixed period, a deletion instructing parameter is outputted to an instruction parameter file 23 for the program. Thus a deletion processor 31 inputs the deletion instructing parameter to collate it with a working result file. If the designated program is not present in the file, the designated program is deleted out of the file 21.
