Title: Digital information reproducing circuit
Inventor: SUDOU KENGO
IPC: G11B5/09
Filed: 1981-06-03
Abstract: PURPOSE:To prevent malfunction in the course of reproducing digital information recorded on recording media through an NRZI modulation system, by comparing detected signals with signals having preset hysteresis characteristic. CONSTITUTION:Digital information recorded on a magnetic tape is processed through a magnetic head, an amplifier, and a differentiating circuit, and inputted into a zero level comparator. The output SC' of the differentiating circuit corresponding to the digital information 1 is inputted into the positive side of a comparator 6 in the zero level comparator, and compared with a comparison signal SE of the negative side input. When SC'>SE,an output SF is generated. The output SF is converted in level at a coefficient circuit 7 by a negative coefficient and a signal SG is obtained. The signal SGis added to a fixed reference level signal SH from a reference level circuit 8 at an adder 9 and the comparison signal SE is outputted. Even in the case of information having relatively long inversion section, malfunction caused by dropping of the differentiate signal to zero level does not occur.

Title: Frequency demodulation circuit
Inventor: YONEYAMA HISAKATSU
IPC: H03D3/06
Filed: 1985-04-24
Abstract: PURPOSE:To reduce the power consumption of a frequency demodulation circuit by providing a current source to the collector terminal of a transistor with a resistance set between the transistor collector and the ground to increase the working speed of the transistor and improve the frequency characteristics of the frequency demodulation circuit. CONSTITUTION:A constant current source 32 is provided to a transistor (TR)13a. When the TR13a is turned off, a parasitic capacity 22 is charged quickly by the source 32. Thus the collector potential of the TR13a is set instantaneously at 'H'. A resistance 31 set between the collector terminal of the TR13a and the ground serves as a current path of the source 32 when the TR13a is turned off. Then the level of a signal G can be changed at a time point 'H' with control of the resistance value of the resistance 31. While the collector potential of the TR13a is reduced down to 0 when the TR13a is turned on. Thus the current of the source 32 flows only to the TR13a and not to the resistance 31.

Title: Horizontal output circuit
Inventor: IWAMA SOICHIRO
IPC: H04N3/227
Filed: 1988-04-08
Abstract: PURPOSE:To prevent a wasteful power consumption by changing a phase and executing a horizontal centering. CONSTITUTION:When a horizontal blanking signal is inputted, a first one-shot multivibrator 2 is operated, and when a prescribed time passes, a second next one-shot multivibrator 3 is operated and the pulse of a constant width is outputted. The pulse voltage is impressed to a horizontal output transistor 4, turned on and a horizontal deflecting pulse occurs at a horizontal deflecting coil 6. At this time, by making variable the setting time of the first one-shot multivibrator 2, the horizontal deflecting pulse 6 is moved, and therefore, while the picture is watched, it is adjusted so as to come to the center of the picture. Thus, without flowing a d.c. current to the horizontal deflecting coil, the horizontal centering can be executed by making variable the phase of a driving pulse.

Title: Manufacture of semiconductor substrate
Inventor: NISHIMURA TAKAYUKI
IPC: H01S5/00
Filed: 1990-03-30
Abstract: PURPOSE:To avoid defects such as dislocations caused by lattice mismatching created at the time of the growth of a GaAs layer and reduce the dislocation density of a GaAs growth substrate which is made to grow on an Si substrate by a method wherein, after an AlAs layer is made to grow at a low temperature, the GaAs layer is made to grow on the AlAs layer at a specific temperature at which the lattice constant agrees with the lattice constant of GaAs bulk. CONSTITUTION:If an AlAs layer is made to grow on an Si substrate at a low temperature (t1), the lattice constant of the low temperature growth AlAs layer on the Si substrate agrees with the lattice constant of AlAs bulk at the temperature (t1) (point P). If the temperature is elevated after that, the lattice constant of the low temperature growth AlAs layer on the Si substrate agrees with the lattice constant of GaAs bulk at a temperature (t2) (point K). If a GaAs layer is made to grow at the temperature (t2), the GaAs layer can be made to grow with the values of the lattice constants of the AlAs layer and the GaAs layer along the direction parallel with the Si substrate agreeing with each other. With this constitution, introduction of dislocations into the growth layer at the time of the growth of the GaAs layer can be avoided and, a dislocation density can be reduced compared to the dislocation density of a growth substrate made by a conventional GaAs low temperature growth method.
