Title: Battery powered lighter using semiconductor crystal circuit - has transistor, diode and thyristor in integrated circuit and has tuning resistance in series with first coil
Inventor: NOZAKI YOSHIRO
IPC: F23Q2/28
Filed: 1977-07-13
Abstract: The battery powered lighter using a semiconductor crystal circuit has three electromagnetically coupled coils (L1,L2,L3) connected to a power source (+V) forming an oscillating transformer, one coil (L3) being of step-up type.
