Title: Voltage controlled oscillator
Inventor: OMORI HIDEKI
IPC: H03B5/32
Filed: 1988-06-30
Abstract: PURPOSE:To use a piezoelectric vibrator and to vary and oscillated frequency largely by constituting the oscillator with an amplifier having a piezoelectric vibrator and two load capacitors or over in its feedback circuit and applying a control voltage to plural load capacitors simultaneously. CONSTITUTION:The voltage controlled oscillator is composed of an amplifier 2 having a piezoelectric vibrator 1 and two load capacitors 3-3, 3-5... or over in its feedback circuit and its oscillated frequency is varied by controlling a voltage applied to one load capacitor 3-3, and a voltage from a DC power supply 6-1 is applied via a terminal 5 to one load capacitor 3-3 loaded to the vibrator 1 to vary the capacitance. Since a voltage from a DC power supply 6-2 is supplied simultaneously to the other load capacitor 3-5, the capacitance is similarly varied. In this case, the capacitance of the capacitors 3-3, 3-5 is varied at the same time to increase the load capacitance to the vibrator 2 larger in comparison with the change of one capacitor 3-3 only. Thus, the oscillated frequency is varied larger continuously by varying the voltage from the DC power supplies 6-1, 6-2 continuously.

Title: Film tape carrier for tab
Inventor: TAKEDA YASUSHI
IPC: H01L21/60
Filed: 1988-06-30
Abstract: PURPOSE:To decrease the hardness of a film tape carrier, to increase its elongation, and to improve its life against a repetitive fatigue by using a copper foil and a rolled copper which is strong against the repetitive fatigue. CONSTITUTION:A film tape carrier 1 for TAB is composed of a base material 2 made, for example, of a polyimide film or the like opened with continuous perforations 2a at both lateral edges and a predetermined through hole 2b for an IC chip, and a copper foil 3 patterned in a predetermined lead shape on the material 2. The foil 3 is annealed to be recrystallized by heating, for example, a rolled copper at 180-280 deg.C, then holding it at the temperature for approx. 1 hour, and then gradually cooling it. Thus, when it is annealed by heating it at 180 deg.C or higher and holding it at the temperature for approx. 1 hour, its hardness Hv becomes 20-35, which is much reduced as compared with approx. 80 of the hardness Hv when it is not annealed, thereby remarkably increasing its fatigue life.
