Title: Method for manufacturing electronic parts
Inventor: MATSUDA KATSUJI
IPC: H01L21/78
Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To prevent a covering material from being pulled at a substrate edge and being extended, to prevent the tailing of the covering material from being generated, and to cut each element from a unit substrate by cutting each element while the surface of the unit substrate is being exposed without providing any covering material at the crossing part of cut lines. SOLUTION: After a plurality of thin-film coil patterns 1 are formed on a unit substrate 3, an insulation/protection film 2 for protecting the thin-film coil pattern 1 is formed on a surface where the thin-film coil pattern 1 of the unit substrate 3 is formed. However, the insulation/protection film 2 is not formed at a crossing part 5 cut lines A and B, and the unit substrate 3 is exposed at the crossing part 5. Then, the unit substrate 3 where the thin-film coil pattern 1 and the insulation/protection film 2 are formed is cut along the cut lines A using the dicing method, thus dividing into stick shapes. Then, stick-split unit substrates 3a are cut along the cut line B.

Title: Differential amplifying circuit
Inventor: OOGAWARA TOSHINORI
IPC: H03F3/45
Filed: 1982-05-21
Abstract: PURPOSE:To prevent the output from being saturated at the high voltage side of a power supply, even if a non-inverting input is a common voltage or below, by connecting an emitter of a clamping transistor (TR) to a non-inverting input terminal and a collector to an output controlling TR respectively. CONSTITUTION:The emitter of the clamping TR10 is connected to the non-inverting input terminal 21, the base is to a common 20 and the collector is connected to a collector of the output controlling TR6 respectively. In the constitution like this, when a non-inverting input e+ goes to negative, a base current starts flowing from the base of the TR10 to the emitter. Since the collector potential of the TR6 is more positive than the emitter potential of the TR10, the TR10 is conductive. A constant current connected to the collector of the TR6 is by-passed with the TR10 to decrease the collector potential of the TR6. As a result, TRs 7, 9 turn on and a TR8 turns off, then an output eO is kept to a common voltage level.
