Title: Phase synchronizing loop
Inventor: MORIYA YOUICHI
IPC: H03L7/093
Filed: 1980-04-25
Abstract: PURPOSE:To obtain an optimum phase synchronized performance, by detecting the ratio of noise power to signal power (CNR) of the input and by utilizing this detection quantity to adjust the gain of the sensitivity change loop of the phase detector. CONSTITUTION:A phase synchronizing loop is formed by input terminal 1, phase detector 2, loop filter 3, voltage variable gain loop amplifier 7, and voltage control oscillator 5. The phase error signal is generated in detector 2. Capacitor 8 takes out the error voltage only due to noise components, and noise components corresponding to CNR are rectified by full wave rectifying circuit 9. LPF10 smooths the rectification output to determine the control speed of the gain for amplifier 7. Though the sensitivity of detector 2 is changed by the change of CNR, the characteristic of the loop is always kept constant by giving the inverse gain change to amplifier 7.

Filed: 1994-03-28
Abstract: PURPOSE:To prevent occurrence of a resin crack by a construction wherein leads for fixing an element mounting part are made to project from four corners of the element mounting part and projections are formed on four lateral sides of the element mounting part respectively. CONSTITUTION:Leads 3 for fixing an element mounting part project from four corners of the element mounting part 1 and the central part of each lateral side of this element mounting part 1 is shaped in a projection. By this flat surface structure, a space between the part shaped in the projection and a lead 2 is also made small. Since a thermal stress in the vicinity of the lower end of the element mounting part to be a starting point of a resin crack of a semiconductor device can be relaxed, therefore, an effect of preventing occurrence of the crack is produced. Even when the crack occurs, moreover, an effect of checking development of the crack along the lower end on the lateral side of the element mounting part is produced, since the lateral side is not shaped in a straight line, but shaped in a stepped form. Since the resin crack can be checked, besides, the reliability in humidity resistance of the semiconductor device is improved and further a phenomenon of increase of a stress can be lessened on both long and short sides of the element mounting part 1.
