Title: Magnetic recording and reproducing device
Inventor: SHIBUE SHIGENORI
IPC: H04N9/793
Filed: 1985-06-20
Abstract: PURPOSE:To exactly discriminate a multitrack system MTS mode by providing a means to detect the burst signal of a reproducing chrominance signal and to discriminate the mode based on the detected burst signal. CONSTITUTION:The burst signal extracted by a burst extraction circuit 23 and the output of a standard crystal oscillator XO 24 have a phase difference of pi/2 as shown in figure (b). After phase-delaying the output of the XO 24 by a phase shifter 26 by 90 deg. as shown in figure (c), the output is phase-detected against the burst signal by a phase comparator 27. The output signal amplitude of the comparator 27 behaves as a reference that is its highest level, and its level varies due to the burst phase as shown in figure (d). When the burst signal lacks, the output level of the comparator 27 lowers and gets out of the threshold of a comparator 28, and therefore, the output of the comparator 28 reverses as shown in figure (e). Consequently, the MTS mode can be discriminated by means of this output signal of the comparator 28.

Title: Manufacture of semiconductor device
Inventor: YOSHIDA HIROSHI
IPC: H01L29/72
Filed: 1986-06-11
Abstract: PURPOSE:To reduce the leakage current of a semiconductor device by ion implanting twice a reverse conductivity type impurity to a substrate to an emitter region in a base region and a cathode region in an anode region by altering the conditions of a high acceleration voltage and a low acceleration voltage. CONSTITUTION:Reverse conductivity type impurity to a substrate 10 is implanted twice to emitter regions 21, 22 in a transistor base region 20 and cathode regions 31, 32 in an anode region 30 by altering the conditions of high and low accelcration voltages. Then, it is heat treated to form the junction of the cathode regions shallower than that of the emitter regions and at high density. Since the ion implantations are divided into two in this manner and the second implantation is to near the surface by avoiding the first deep implantation, a crystal defect is suppressed as compared with a conventional method for ion implanting a large quantity of ions, resulting in a decrease in the current leakage of a constant-voltage diode.
