Title: Controlling system for shape of strip
Inventor: SHIMODA MICHIO
IPC: B21B37/32
Filed: 1980-10-30
Abstract: PURPOSE: To properly control the shape of a product obtained by a strip rolling process, by developing a shape pattern signal outputted from a shape detector into an orthogonal function matrix of a high-order polynomial, and by controlling the manipulated variables of an actuator according to the coefficient of said orthogonal matrix.  
     CONSTITUTION: At rolling a strip, a shape detecting output signal 21 of a shape detector 1 is corrected by an elongation operator 2 into an elongation signal 22 which is then outputted. This signal is computed by an orthogonal function  developing computer 3, whose output is then inputted to a reducing screw position control computer 5 and a bending control computer 6. An error of a developed orthogonal matrix from the actually measured value is inputted to a local  defect detecting computer 4 whose output is then inputted to a coolant nozzle  control computer 7. Each of computers 5, 6, 7 computes the correcting values  for the reducing screw position, the bending, and the coolant distribution; these  correcting values as control actuators are inputted to a reducing screw position  controller 10, a bending controller 11, and a coolant valve controller 12; hereby,  the shape of the strip is controlled.

Title: Frequency synthesizer
Inventor: MATSUURA TAKASHI
IPC: H04B1/40
Filed: 1981-09-28
Abstract: PURPOSE:To improve the linearity and stability, through the application of negative feedback, by frequency-modulating a transmission carrier wave obtained at the output of a transmission oscillator, picking up a modulation signal again, and summing the signal to a modulation input signal in opposite phase. CONSTITUTION:A reception local oscillation frequency transmitted to a terminal 3 and a transmission carrier frequency transmitted to a terminal 4 are given to a mixer 31, and the frequency difference between two inputs is obtained at the output. This output frequency is frequency-divided at a frequency divider 32 and demodulated at a frequency demodulator 33. This demodulated output is a signal equal to a modulation input signal given to a terminal 34 and summed at an adder 35 in the phase opposite to this signal. The output of the adder is applied to the control input of a voltage controlled oscillator 21 from a terminal 26. Since the signal passing through the voltage controlled oscillator 31, the mixer 31, the frequency divider 32 and the demodulator 33 is negatively fed back to the modulation input signal, the linearity and stability of the device can be improved.

IPC: H01L29/80
Filed: 1978-12-12
Abstract: PURPOSE: To obtain a delicate and minute pattern of a gate and a source or drain by a method which does not relies upon photoetching.  
     CONSTITUTION: An insulating film 2 and a polysilicon film 3 are superposed to a substrate 1 carrying an n - -layer overlying an n + -layer. In the film 3, p- and n-regions are selectively formed. p-Type patterns 4-1, 4-3... and an n-type pattern 4-2 are formed in the laminated layers at the minimum photoetchable pitch and a polysilicon film 5 of a thickness t o  is laid thereon. As a result of a subsequent spatter etching by a depth t o , films 5-1∼5-3 of minite width t r  are formed in the side surface by self-alignment. After a deposition of an insulating film 6, the laminated structure is subjected to a heat treatment so that impurities are diffused from the films 4-1∼4-3 into the substrate through the films 5-1∼5-3 to form p-layers 7, 9 and an n-layer 8. Subsequently, the insulating film 6 is opened at its portions above the patterns 4-1∼4-3 to form wirings 10∼12. This method makes it possible to produce a multi-channel vertical junction type field effect transistor of minute structure and having a distinguished performance.

Title: Circuit and device for power source
Inventor: INABA KATSUMI
IPC: H02M3/155
Filed: 1999-06-01
Abstract: PROBLEM TO BE SOLVED: To obtain a switching power source circuit which can further reduce consumption power during standby. SOLUTION: The magnitude of a voltage obtained by rectifying directly a commercial AC voltage is detected with a rectified voltage detecting circuit 3. The detected voltage inputted in a control circuit 6, which controls switching operation on the basis of the detected voltage, in such a manner that a switching element 5 is turned in the state on, only during the period that the rectified voltage is lower than a prescribed value. As a result, the product of the voltage and current, when the switching element turns on, is made small, and switching loss is reduced. A reverse current preventing circuit 4 is arranged in mediately in front of the switching element 5, and switching is performed only when the rectified voltage is low. As a result, the voltage on the output side becomes higher than the voltage on the input side, and a reverse current is prevented.

IPC: H01L21/8238
Filed: 1986-06-30
Abstract: PURPOSE:To obtain a well region having a flat surface by previously indenting the surface of a substrate in an opening section through etching at a specific rate to the thickness of an insulating film. CONSTITUTION:Since an SiO2 film 22, to which an opening is bored, is 1mum thick, a substrate 21 is etched up to depth of 2500-3500Angstrom from the surface 21A of the substrate to the film 22, thus forming an indentation 25 to the substrate 21. A surface 25B vertical to a surface 25A parallel with the substrate surface 21A is shaped in the indentation section 25, and the surface 25B is formed in a (100) face though the surface 25A is shaped in a (100) face. Consequently, the slow growth rate of a crystal formed by the surface 25B is compensated by previously shaping a seed crystal by the surface 25B, thus preventing the formation of a facet. Accordingly, a flat Si layer 26 is shaped onto the substrate.

Filed: 1995-05-19
Abstract: PURPOSE: To enable the frequency of RF pulses to be measured at an RF signal frequency with high precision by computing the RF pulse stream frequency by adding an intermediate pulse stream frequency and a control frequency. CONSTITUTION: An input signal generated by an unit under test UUT device is converted to a pulse stream of a low frequency having an intermediate frequency IF. A mixer 22 receives as input a test signal from a signal supply source 20 and a control frequency generated from a local oscillator 24 and outputs an IF signal as a difference between those frequencies. The IF signal is passed through a BPF26 so as to eliminate undesirable high frequency component. The IF signal is subjected to sampling by means of a digitizer 28, transferred to a signal processor 30 and subjected to frequency analysis. The desirable frequency of the IF signal is about 20 to 30% of a digitized sampling frequency. It is desirable that an least two cycles of the IF signal passed a down converter under the sampling frequency of a selected digitizer exist inside of each captured pulse of test signal.
