Title: System detecting each voltage pulse having specific dimensions
Inventor: JIYOSEFU EICHI KOORUZU
IPC: H03K5/1252
Filed: 1990-04-03
Abstract: PURPOSE: To generate an output pulse having size of a voltage for discriminating between a horizontal synchronization pulse and a color burst signal on each horizontal line by using an integrated circuit chip equipped with transistors(TRs) and setting sizes of those TRs in a specific pattern. CONSTITUTION: Because of the individual sizes of N channels TRs in a CMOS inverter 24, the inverter 24 operates as a high-gain differential amplifier. When a negative peak of a synchronization signal drops below a half of a supply voltage, a large negative voltage pulse is generated at an output terminal of an inverter 30 and impressed to the gate of a TR 32. An inverter 36 has N- channel TRs having sizes selected so that an input functions as a differential amplifier which is amplified regarding an internal difference voltages that is slightly more positive than the voltage of the inverter 24. Therefore, the inverter 36 actually judges as a voltage pulse having a negative synchronization pulse peak and generates a positive pulse at its output terminal.

Abstract: PURPOSE:To satisfactorily perform lap welding of metallic sheets. CONSTITUTION:Two metallic sheets 3 and 4 are superposed on each other and a metallic sheet 2 is further placed on a weld line of the metallic sheets 3 and 4 along the weld line on the upper side metallic sheet 3. When the metallic sheet 2 is irradiated with a laser beam 1, the metallic sheet 2 and the two metallic sheets 3 and 4 to be welded are melted by a high temperature generated by the laser beam 1.
