Title: Transmission method for interference reduction signal in mobile communication
Inventor: SAKAMOTO MASAYUKI
IPC: H04B1/10
Filed: 1987-03-20
Abstract: PURPOSE:To improve the reception quality by detecting a rapid level change in a demodulation signal due to capture effect at the reception side when each electric field of a desired wave and an interference wave is fluctuated respectively and its intensity is inverted so as to control the operation of the reception system. CONSTITUTION:An output of a frequency detector 23 is branched into three and inputted respectively to a switching circuit 29, a signal recording/ reproducing circuit 30 and a level discrimination circuit 28. The signal recording/ reproducing circuit 30 is a circuit storing the output of a frequency detector 23 up to a prescribed preceding time. After an input signal is converted into a digital signal by an A/D converter 35, when the output of the level discrimination circuit 28 is reset, that is, the output of the frequency detector 23 is a discriminated level or below, the signal is read sequentially in a shift register 36. When the output of the circuit 28 is set, that is, the output of the detector 23 reaches the discrimination level or over, a write/read control circuit 38 stops the write into the shift register and outputs the signal stored in a D/A converter 37 sequentially.

Title: Stereo noise reducing method and its device
Inventor: AMASAWA KIYOSHI
IPC: H04B1/10
Filed: 1980-05-16
Abstract: PURPOSE:To suppress stereo noises without the deterioration of separation, by controlling a synthesizing circuit of L, R channel signals, according to the signal level difference of the L, R channel signals. CONSTITUTION:A multiplex stereo signal from an input terminal 1 is separated into an L signal 3 and an R signal 4 at a separation circuit 2. Further, the level difference of the L, R signals is detected at a signal difference detecting circuit 7, and if the level difference is small, an L channel signal synthesizing circuit 5 and an R channel signal synthesizing circuit 6 are controlled via a control circuit 8 for the operation so that both the signals can be synthesized strongly. Thus, the stereo noises can be reduced. Further, if the level difference of L, R is great (in case of strong stereo) inversely, control is made so that the synthesis can be weak for separation. Moreover, if the level difference is vo or lower as shown in Figure, the synthesizing circuits 5, 6 can be controlled so that complete monaural can be obtained.

Title: Stopper for motor
Inventor: YASOHARA MASAHIRO
IPC: H02P3/18
Filed: 1988-03-17
Abstract: PURPOSE:To add the stopping function of a motor without providing an exclusive terminal for stopping the motor by detecting that a signal exceeding the output signal range of a speed detector is input as a stop command signal thereby to stop the motor. CONSTITUTION:A motor speed detector 30 is limited in its output signal range to a predetermined level. A stop command detector 40 detects that a signal exceeding the output signal range of the detector 30 is present as a stop command signal at the output of the detector 30. The stop command signal is generated by forcibly setting a terminal 80 to a low level. A conduction switching circuit 26 stops a motor by the output of the detector 40.

Abstract: PURPOSE:To improve considerably the operability when a linear pattern is inputted from a data tablet, by calculating the degree of difference between respective parts of a standard pattern and an input pattern. CONSTITUTION:An input device 1 takes in the coordinate value of a writing point for every stroke and transmits it to a stroke row extracting device 3.

Title: Ceramic multilayered board manufacturing method
Inventor: ARAKI HIDEAKI
IPC: H05K1/02
Filed: 1996-03-21
Abstract: PROBLEM TO BE SOLVED: To reduce deformation and warps of a ceramic multilayer board at baking. SOLUTION: A dummy pattern 25 is screen-printed on an unwanted part outside a part (product part) of at least one of stacked green sheets 21 for forming a ceramic multilayer board, using the same conducting paste as one for printing a conductor pattern 23 on the product part.

Filed: 1990-03-15
Abstract: PURPOSE:To obtain a magnetic disk showing reduction in stress, demagnetization and level-down rate of a magnetic film by specifying the gas pressure and flow rate of O2 gas in a chamber of a sputtering device. CONSTITUTION:In a chamber 1, to which O2 gas is introduced at the gas pressure of 20 mTorr and 80 SCCM (Standard Cubic Centimeters per Minutes) flow rate, O2 ions are made to collide against a Fe target 2 to produce Fe2O3, which deposites on a disk substrate to form a alpha-Fe2O3 film. Then the alpha-Fe2O3 film is heated and subjected to reduction treatment in a H2 atmosphere to be changed into Fe3O4. Then the Fe3O4 is heated in air for oxidation to be changed into gamma-Fe2O3 film which has magnetic properties. By this method, stress, demagnetization and level-down rate of the gamma-Fe2O3 magnetic film formed on the disk substrate can made rather small.
