Although the ignition timing at the start is set in the vicinity in front of an upper dead point where an excellent start property can be provided, an ignition timing at trolleying is necessary to be set at a position delayed a fed degrees. Then, sparking is effected at an upper dead point of 5 deg.-10 deg. during a period of time determined by a setting time variable control means 43 and after that the pulsar coil 39 and a pulsar coil 40 are bypassed by a timer circuit 41. With the arrangement, a starting property is improved and acceleration just after the start can be smoothly effected.

IPC: G11C7/10
Filed: 1997-07-25
Abstract: PROBLEM TO BE SOLVED: To enhance the processing speed of a semiconductor memory and to reduce power consumption of the memory by generating the output of a zero level from an output driving while directly controlling the output of a data output buffer by using an address transition detection signal in an address transition.

Abstract: PURPOSE:To prevent such a phenomenon as half-cooked rice by constituting a rice cooker so that a timer is operated at the time point when an inner rice-cooking pot is raised, and when the inner rice-cooking pot is installed within the prescribed time, the process before the inner rice-cooking pot is raised is restarted, but unless the inner rice-cooking pot is installed within the prescribed time, the warming control is stopped. CONSTITUTION:After rice cooking is started, whether an inner rice-cooking pot 3 is installed or not is decided in the warming process after the rice cooking and the steaming processes, and when it is raised and not loaded, the control is stopped, and whether it is raised in the warming process or not is decided by a warming process deciding means. Unless it is in the warming process, furthermore, whether the inner rice-cooking pot is installed in the rice cooker or not is decided, and when it is loaded, the control is restarted. Also, when the raising time point of the inner rice-cooking pot 3 is in the warming process, a timer is operated. When the inner rice-cooking pot 3 is installed immediately, the control is restarted. When time elapses in a state that the inner rice-cooking pot 3 remains raised, and the time when the inner rice-cooking pot 3 is not installed yet exceeds 30 seconds, the warming control is stopped. In the case rice and water are put newly into the inner rice-cooking pot and rice cooking is executed, since the rice cooker is returned already to a state before the start, half-cooking, etc., do not occur.
