IPC: H03H17/00
Filed: 1996-03-19
Abstract: PROBLEM TO BE SOLVED: To obtain a converter with a DC component removing function easily realizing non-adjustment and high stability by equipping a digital high-pass filter for removing DC components outputted from an A/D converter. SOLUTION: An analog stereo composite speech signal is inputted from a speech signal input terminal 7. This is removed of DC components and converted into a digital signal by the A/D converter with the digital high-pass filter. Next, the signal removed of the DC current is multiplied by a maximum frequency shift (p) by means of a multiplier 10 and added with wc T which is T times the sampling frequency of a carrier frequency and then supplied to DDS 12. The signal is digitally FM-modulated by DDS 12 and outputted as an FM-modulated signal from a modulated wave signal output terminal 8 through a D/A converter 13. Then non-adjustement and high stability are easily realized becase of the removal of DC components by the digital high-pass filter.

Title: Video frame time code correcting method and video system using time code
Inventor: KOJIMA HARUHIKO
IPC: H04N5/93
Filed: 1996-03-19
Abstract: PROBLEM TO BE SOLVED: To improve the control accuracy of video equipment by correcting the deviation of time information from the timing of reference time while using a time code applied corresponding to a plurality of video frames. SOLUTION: A time code generator 2 receives a reference video synchronizing signal and the second pulse signal of reference time, generates the time code and outputs it. A computer 1 for control has a CPU for controlling various kinds of arithmetic and exchange of data and outputs a control signal corresponding to the reference video synchronizing signal and the time code outputted from the time code generator 2. When the time contents expressed by the time code applied to the video frames are deviated from the time to send out these video frames, the code generated by the time code generator 2 is converted. Thus, since the deviation of time information from the timing of reference time is corrected, the control accuracy of video equipment can be improved.

When ON action is executed according to the control command CS received in the gate, the electric potential is made to be lost by short-circuit and the slave transistor 40 is made to execute the OFF action, so that slave current Id disappears. On the contrary, during OFF action normal slave current is generated in the salve transistor 40.

Title: Variable gain type amplification circuit with little distortion
Inventor: ENDO KATSUHIRO
IPC: H03G3/10
Filed: 1987-03-20
Abstract: PURPOSE:To control an amplification signal to be in little distortion by keeping the bias of a bias control pole constant and altering the electric potential of a source or an emitter. CONSTITUTION:In order to make the voltage VGS between a gate and the source zero V, a G point and the source S are set in the same electric potential by a resistance RG and an FET always executes an A-grade amplifying action. An automatic gain control electric potential VAGC is supplied to the source side so as to alter the voltage VDS between a drain and the source. If a large amplitude input is introduced in a circuit, the VAGC is automatically increased by feedback and a current flows in the resistance RS. Then a source electric potential VS rises and the VDS is decreased. And the gain lowers, so that a signal output in an amplification limit is outputted. Thus, an output wave with little distortion can be obtained by lowering the gain corresponding to the large amplitude input wave.

Abstract: PURPOSE:To attain the high speed of learning convergence by learning a learn ing pattern in which a teacher pattern is the subset of an input pattern as a first step, and in a second step, learning the learning pattern to be learnt originally by making the learnt result of the first step be an initial value. CONSTITUTION:In the first step, an input pattern set A is inputted to the input of the neural network and the subset A0 of the input pattern set A is given as the teacher pattern, and learning is executed. In the second step. first of all, the subset A0 of the input pattern set A is given to the input of the neural network, and the subset B0 of a teacher pattern set B corresponding to the subset A0 of the input pattern set A is given as the teacher pattern. The learning part of the neural network learns a conversion rule from A to B on the basis of these input data. Subsequently, the learning is executed by giving successively the rest of the set A0 and the rest of the set B0. Since network structure after the learning of the first step is preserved and made to be the initial value of the learning of the second step, the number of times of the learning of the second step is reduced.

Title: Etching and apparatus therefor
Inventor: SADAOKA MASATO
IPC: H01L21/3065
Filed: 1986-03-24
Abstract: PURPOSE:To improve the number of a material under treatment and the accuracy in size of etching, by forming a magnetic field so that the plasma of reacting gas is distributed in a specified pattern in the axial direction of a treating chamber, and periodically changing the positions of the material under treatment and a sample stage in the axial direction. CONSTITUTION:The density of the plasma of reacting gas 4 in a treating chamber 1 is distributed in the axial direction with a magnetic field formed by a magnetic force applying means 12. A sample stage 2 is lifted and lowered in the axial direction of the treating chamber 1 at a specified period. The etching speed of a sample at a specified height H is made to balance with a protecting-film forming speed. The protecting film is used to protect the side wall of the cross section of a nonvolatile material to be etched, which is grown with the reacting gas 4. The kind and the composition of the reacting gas 4 are appropriately selected. Then, the etching is carried out at a position higher than the height H in the treating chamber 1. The protecting film is formed by the deposition of the nonvolatile material to the side wall part of the cross section in etching at a position lower than the height H. Therefore the etching can be performed in a relatively short time with excellent accuracy of the size of the pattern that is formed on a material 3 under treatment.
