Title: Semiconductor non-volatile memory
Inventor: HAYAKAWA KOICHI
IPC: H01L21/8247
Filed: 1996-10-28
Abstract: PROBLEM TO BE SOLVED: To enable reduction in thickness of a gate insulating film and enable low-voltage operation while maintaining stable operation as in a conventional technique, by forming a floating gate using a material with a conduction band energy level lower than that of silicon. SOLUTION: A floating gate 13 formed on a semiconductor substrate 11 via a gate insulating film 12 is made of a material having a conduction band energy level lower than that of silicon. For example, as the material having a conduction band energy level lower than that of silicon, polycrystal germanium or a mixed crystal of silicon and germanium is used. Thus, an energy barrier of the gate insulating film 12 for accumulating electric charges similarly to a conventional technique may be made small. Therefore, the thickness of the gate insulating film 12 may be made smaller than in the conventional technique, and tunneling is more likely to occur. Thus, the device operates even at a low voltage, enabling writing and reading at a low voltage.

Title: Immediate ignition device at starting time using ignition control
Inventor: OKAHARA AKIO
IPC: F02P5/15
Filed: 1996-10-28
Abstract: PROBLEM TO BE SOLVED: To immediately ignite from the first compression upper dead center at the starting time by providing an immediate ignition control part at the starting time for forming an ignition signal immediately when the compression upper dead center is detected by a crank position detection switch, when a starter switch for starting an engine is turned ON. SOLUTION: When a starter switch 8 is turned ON, it is judged at an added control part 2 whether either one of crank position detection switches 5-1 to 5-4 is in OFF state or not. At no OFF state, as a cam shaft is rotated in response to the rotation of a crank shaft by the drive of a starter, it is detected by this rotation that either one of the crank position detection switches 5-1 to 5-4 is at first changed from ON state to OFF state. When either one of the crank position detection switches 5-1 to 5-4 becomes OFF state, an immediate ignition is carried out. In other words, the ignition of a cylinder in response to the crank position detection switch which is in OFF state is carried out and thereafter, the ignition is shifted as usual.
