Filed: 1982-06-02
Abstract: PURPOSE:To improve the current gain and the frequency response of a lateral P-N-P transistor by giving density gradient to the N type base region, by adding an N type impurity diffused layer. CONSTITUTION:The N type impurity of approx. 1X10<18>atom/cm<3> surface density is deposited at the part to serve as the P type emitter region 1 and heat-treated, resulting in the formation of the N type impurity diffused region 4. The impurity density in the neighborhood of the surface is approx. 1X10<17>atom/cm<3> at the part to serve as the P type emitter region 1, and becomes lower as it goes close to P type collector regions 2. Heat treatment is performed after such deposition that the surface densities of the P type emitter region 1 and the P type collector regions 2 become approx. 1X10<18>atom/cm<3>. Thus, the N type impurity diffused region 4 functions as the base region of the lateral P-N-P transistor, therefore it follows that density gradients 4' are regarded to be given to the base region.

Title: Data separation circuit
Inventor: NAGAI TSUNEO
IPC: G11B7/004
Filed: 1985-04-30
Abstract: PURPOSE:To attain correctly the demodulation of data other than a dropout section by detecting the dropout in a modulation signal and inserting a prescribed signal during the dropout so as to eliminate the step-out of synchronization of a PLL. CONSTITUTION:A dropout discrimination section is discrimination depending on the number of change points of a read modulation signal 101 included in the discrimination section by using a signal with a prescribed period generated from a reference clock generating circuit 203. The length of the discrimination section and the number of change points are decided by checking in advance the period of the modulation signal and the sensitivity of the PLL to the dropout signal. If any dropout is detected, a dropout compensation circuit 205 inserts an insertion signal (g) sent from the reference clock generating circuit 203 and inputs the result to a post-stage as a dropout compensation output (f). Thus, even when any dropout takes place in the input signal (read modulation signal), the step-out of the synchronization of the PLL causing erroneous demodulation of the data other than the dropout section is avoided so as to improve the reliability of demodulation.
