Title: Waveform shaping circuit
Inventor: SANO TOSHIO
IPC: H03K5/1252
Filed: 1994-05-19
Abstract: PURPOSE:To provide an output of an accurate square wave not including an abnormal pulse even when noise signal is somewhat included in an input signal due to impedance mis-matching of a transmission line or the like. CONSTITUTION:Four comparators 1a-1d are used to compare an input signal with reference voltages obtained by dividing a power supply voltage with plural resistors R1-R5 thereby obtaining comparator outputs D1-D4 whose levels differ from each other. An arithmetic output section 2 comprising combinations of plural logic elements 3-9 changes an input logic discrimination level based on the comparator outputs D1-D4 depending on a preceding level path and obtains an output signal based on an input logic discrimination level subjected to change thereby preventing it that the output signal includes a noise signal or an abnormal signal due to the reflection on a transmission line.

Filed: 1989-05-22
Abstract: PURPOSE: To improve the resolution of an optical scanning system by providing a non-linear layer between a transparent substrate and a reflecting layer to generate an identification state in a scanning spot, and to make an effective scanning spot smaller than an original scanning spot. CONSTITUTION: The information recording area in an information surface 2 of a record carrier is alternately formed with a different length of intermediate area 6 and a pit 5. And the non-linear layer 22, increasing a transparent light beam when an incident spot (b) exceeds a prescribed intensity level, is formed between the transparent substrate 7 and the reflecting layer 20. And the material of the layer 22 is selected so that an energy distribution in a diffraction limit scanning spot S is increased in the center area S' of the spot S. Therefore, the small information area of the record carrier is read out with the effective scanning spot S', thereby reading out smaller objective part than the original scanning spot. By this way, the resolution of the optical scanning system is improved.

Abstract: PROBLEM TO BE SOLVED: To eliminate the influence of residual electric charges that is generated in a protective film by forming a field plate electrode and a second electrode that are connected to a first region and a second region, respectively, through contact holes in an insulating film, and removing the protective film above the end of the field plate electrode to form a trench. SOLUTION: An electrode 26 and a field plate electrode 27 formed through contact holes 24, 25 are brought into contact with a n-type substrate 20 and a p-type region 22, and a protective film 28 is formed on an insulating film 23 and the electrodes 26, 27. A trench 31 of a specific width W1 is formed in the protective film 28 in an area covering the vicinity of an area where concentration of electric fields is apt to be caused by an end 30 of the field plate electrode 27. Even if reverse-biased, electric charges are prevented from being produced in the protective film 28 due to the influence of the electric fields because there is no protective film 28 in this area. This prevents electric charges from remaining in the protective film 28, and avoids degradation in the characteristics of the semiconductor device, fluctuation in breakdown voltage and shortening of life.

Filed: 1996-04-24
Abstract: PROBLEM TO BE SOLVED: To perform the stable feedback control by rectifying the load end voltage signal via a 2nd rectifier circuit and performing the feedback control based on the rectified signal. SOLUTION: The 1st and 2nd rectifier circuits 14 and 15 of a feedback control part 9 detect the absolute value of inputted AC signals and then average them. When the voltage value of the rectified signal SD2 outputted from the circuit 15 reduce, an integrating circuit 16 gradually reduces the voltage value of the integrated signal according to the integration constant. On the other hand, the circuit 16 gradually increases the voltage value of the integrated signal according to the integration constant when the voltage value of the signal SD2 increase. In such a way, both circuits 14 and 15 generate the rectified signals SD1 and SD2 , i.e., the DC value by rectifying the input AC signal and the inter-terminal voltage signal SC respectively. Then a multiplier 11 controls the gain based on the value that is calculated by integrating the rectified voltage, i.e., the DC voltage.
