Filed: 1996-06-05
Abstract: PROBLEM TO BE SOLVED: To provide a controller for a gas cooker in which even with any failure erroneous judgement of a combustion state is eliminated, and a switch operation is recognized on a safety side for ensurance of safety. SOLUTION: AC voltage of an AC power supply 1 is applied to a flame rod 2 for sensing a flame and is opened and closed with a phototriac 10. Upon combustion a pulse shaped flame rod current 7 flows through the flame rod 2 via a flame which is converted to a pulse shape combustion detection voltage signal 8 with a field effect transistor 3 and is inputted into a microcomputer 6. The combustion detection voltage signal 8 and the waveform of a switching pulse 9 for driving the triac 10 are compared, and if they are same phase, then it is judged that the state is a combustion state while if 0 volt level, then it is judged the state is a non-combustion state.  In this case, when the field effect transistor 8 is opened and troubled after the detection of combustion, voltage of a drain 4 becomes a constant level of DC 5V so that the failure can be judged for discrimination of the combustion state and the trouble state.

Filed: 1990-05-31
Abstract: PURPOSE:To average a current at the writing time and to enable the write-in at high speed in accordance with a large capacity EPROM by performing the write-in in the manner of dividing and driving plural data by writing signals of different timing with the writing operation at one time. CONSTITUTION:By the input of an external programing signal PGM, the writing signals P1,P2 are generated in a write signal generating circuit Def, then first of all, the data are written in the corresponding memory cells by the writing circuits WC0, WC2, WC4, WC6 in accordance with the writing signal P1. Next, the data are written in the corresponding memory cells by the writing circuits WC1, WC3, WC5, WC7 in accordance with the writing signal P2 having the timing delayed more than that of the writing signal P1. With the timing differ ence between the writing signals P1 and P2, the writing current is averaged, since a large writing current generally flows in the EPROM cell at the initial stage of the write-in start and this current becomes small according to the progress of write-in. Thus, the write-in can be performed at high speed in accor dance wth the large capacity ERROM.

Filed: 1995-06-09
Abstract: PURPOSE: To accurately discriminate an acceptable product by judging a molding as acceptable product if a reflected wave signal is continuously detected up to the time of completing the compressing step, and judging it as a defective product when it is not continuously detected. CONSTITUTION: While the reflected wave signal (B1 wave) of the resin of an ultrasonic signal emitted toward resin in a mold cavity 25 is detected by an ultrasonic sensor 18 during the compressing step, it indicates that a compression force is applied from the mold clamping side to the resin in the cavity 25. If the B1 wave is not detected, the compression force of the mold clamping side is not added to the resin. That is, the resin is not brought into close contact with the cavity 25 wall, and the state that a gap is formed is indicated. The presence or absence of the B1 wave is discriminated to simply and accurately detect the compressed state of the resin during the compressing step.
