Title: Level control circuit
Inventor: NARUI YOSHIHISA
IPC: H03G3/02
Filed: 1990-05-14
Abstract: PURPOSE:To decrease the circuit scale and to reduce the cost by controlling levels of plural waveforms with a single D/A converter. CONSTITUTION:Each fundamental wave is time-divided by a 1st changeover circuit 1 and a synthesis signal obtained by time division is subject to level modulation by a D/A converter circuit 2 and the result is distributed into each fundamental wave at a 2nd changeover circuit 3. Since a level control data of each fundamental wave is inputted to a data input of the D/A converter circuit 2 synchronously with the changeover of the 1st and 2nd changeover circuits 1,3, each fundamental wave whose level is controlled by a level control data is obtained at an output of the 2nd changeover circuit 3. Since the signal is processed by only the single D/A converter circuit 2 regardless of number of the fundamental waves in this way, the level control circuit whose circuit scale is small and whose cost is low is realized.

IPC: H02M3/28
Filed: 1994-06-06
Abstract: PURPOSE:To reduce switching loss by connecting a capacitor between an output terminal of a complementary transistor(TR) and a gate of a switching element. CONSTITUTION:A pulse voltage whose level is between a power supply voltage and an earth potential is outputted from output terminals of complementary TRs 5, 6 and its waveform has a slow rising from the earth potential and a slow falling to the earth potential. When its output voltage is fed to the gate of a switching element 1 via a capacitor 7, a voltage divided by the input capacitance of the switching element 1 and the capacitance of the capacitor 7 is shifted to be a bipolar gate voltage, and the threshold level of the switching element 1 is set to the steep part of the rising and the falling of the gate voltage. Thus, the speed of on/off of the switching element 1 is increased.

Title: Mos integrated circuit
Inventor: IWAHASHI HIROSHI
IPC: H01L27/10
Filed: 1981-08-07
Abstract: PURPOSE:To produce miniaturized MOSIC's of high density and of wider power margin by forming driving and loading transistors by means of the first and the second layers of polysilicon respectively. CONSTITUTION:When the FET1 whose gate electrode is the first polysilicon layer 1 is used for driving, the threshold voltage Vth can be stable to an extent of the short channel length L so that an element can be miniaturized. When the transistor is used for loading, dependency of the threshold voltage Vth on backgate bias is higher than the FET2 whose gate electrode is the second polysilicon layer 2, so that the ''1'' level of the output is reduced as compared with the case in which the FET2 is used for loading. Therefore, use of the FET2 for loading allows wider power margin. Manufacture of MOSIC's in such a way permits miniaturization of the products, speed-up of operation by reduction in the gate capacitance and formation of EPROM's having stabilized output.

Title: Lead-acid battery
Inventor: YABUKI SHUICHI
IPC: H01M10/06
Filed: 1996-04-22
Abstract: PROBLEM TO BE SOLVED: To sufficiently recover the capacity by charging even after letting a battery stand in the discharged state by limiting the ratio of the weight of a cathode active material of a cathode plate to that of an anode active material of an anode plate to the specified value of less. SOLUTION: A cathode plate is manufactured by applying paste prepared by kneading PbO powder and sulfuric acid to a lead grid substrate, and oxidizing PbO to PbO2 by formation. Similarly, an anode plate is manufactured by reducing PbO to Pb. When PbO of the raw material of the cathode and the anode is converted into the active materials PbO2 and Pb obtained by formation, the ratio of the weight of the cathode active material (g) to the weight of the anode active material (g) is limited to 0.9 or less. A lead-acid battery using the cathode plate and the anode plate has a recovering rate of 90-100% after the battery is let to stand in the discharged state, but in the battery having a ratio of 0.95 or more, the recovering rate is impractically low of 40% or less.

Abstract: PURPOSE: To smoothly move the pickup arm, by driving a motor moving the pickup arm with a voltage rising with time.  
     CONSTITUTION: When the displacement of a pickup stylus 8 increases and the detected output of a coil drive circuit 5 driving it is more than a reference value, the output of a comparator 11 is changed into a differentiation signal through a capacitor C and a resistor R, triggering a monostable multivibrator 22 and a saw-tooth wave generating circuit 23. Thus, a transistor 14 is conducted and the conduction of a transistor 24 is controlled, thereby applying a drive voltage which gradually increases with time to a pickup arm driving motor 15. Accordingly, the pickup arm is smoothly moved to prevent rapid production of movement, allowing to avoid the distortion of playback picture via the stylus 8.

Title: Pcm data compression and restoration method
Inventor: NAKA YUTAKA
IPC: H03M1/12
Filed: 1992-04-16
Abstract: PURPOSE:To attain high density recording and reproduction by sampling analog audio signals at different sampling frequencies, inputting the result to plural buffer memories, and writing PCM data resulting from output data from the buffer memories added with a code in response to the voltage level of the audio signal into a medium. CONSTITUTION:Two A/D converters 2, 3 sample an analog audio signal by using a different sampling frequency to form coded PCM data, which are inputted to buffer memories 5, 6. Simultaneously the analog audio signal passes through a BPF 4 whose lower limit frequency is the upper limit frequency of the analog audio signal and enters a level discrimination circuit 7. A recording control section 10 receives a discrimination signal from the circuit 7 and through a selection section 8 selects the memory 6 when the discrimination signal is at a high level and selects the memory 5 when the discrimination signal is at a low level. Moreover, the control section 10 encodes a level signal from the circuit 7 and synthesizes the code with a selected audio digital signal and the result is fed to a write processing circuit. Thus, the sampling in response to the high/low level of the frequency component is implemented and high density recording is attained.

Finally, the shutter is opened, plasma is generated by the raw material gas for the film B, and accordingly the film B is formed on the film A of the substrate.
