Title: Magnetic recording and reproducing device
Inventor: KOMATSU MASATOSHI
IPC: G11B20/02
Filed: 1988-08-02
Abstract: PURPOSE:To achieve realization with a digital signal processing by making a nonlinear de-emphasis circuit similar to a nonlinear emphasis circuit in form and approximately obtaining its characteristics. CONSTITUTION:The nonlinear de-emphasis circuit 16 is constituted of a high pass filter 31 and a nonlinear limiter 33 similarly to the nonlinear emphasis circuit 12. Then, an inputted regenerative signal 15 is filtered to remove its low band component by the high pass filter 31, and is emphasized on its low level and de-emphasized on its high level by a nonlinear limiter 33. This is deducted from the original regenerative signal 15 of an input signal for the nonlinear de-emphasis circuit 16 by a subtractor 35, so as to obtain the same signal as an input signal 11 for the nonlinear emphasis circuit 12. Thus, the non-linear de-emphasis circuit 16 is made similar to the nonlinear emphasis circuit 12 in form, thus obtaining its characteristics approximately. By this method, it can be realized with the digital signal processing.

Title: Method for forming delta doping layer by chemical organic metal vapor depositing of gaas epitaxial layer on si base plate
Inventor: BIN KOUKI
IPC: H01L21/205
Filed: 1991-07-31
Abstract: PURPOSE: To form a satisfactory GaAs delta-doping layer on an Si substrate while using metalorganic chemical vapor deposition (MOCVD).  
     CONSTITUTION: When forming GaAs delta-doping on the Si substrate while utilizing MOCVD, a buffer layer exceeding 3 μm thickness is formed on the Si substrate and afterwards, the GaAs delta-doping layer is formed at a growing temperature of 700 to 750°C. Thus, the thermal dispersion of a dopant caused by a lot of transitions generated on a GaAs/Si interface can be prevented from being accelerated and an effect improving the characteristics of the GaAs delta- doping layer is generated.

Title: Frequency demodulation circuit
Inventor: MOTONAKANO HITOSHI
IPC: H03D3/00
Filed: 1996-07-22
Abstract: PROBLEM TO BE SOLVED: To reduce the jitter noise of a low band and to absorb the fluctuation of an output current caused by element dispersion by compensating the dispersion of sensitivity due to the dispersion of an incorporated capacitance and the dispersion of a current and adjusting a gain. SOLUTION: Reproduced FM luminance modulation signals PBY are inputted from an input terminal, and demodulated in an FM demodulation circuit block 11. From demodulation signals demodulated and outputted from the FM demodulation circuit block 11, the noise of a high band is eliminated in a low- pass filter 13. Then, delay characteristics are adjusted by an equalizer 14 and the gain is adjusted in a voltage controlled amplifier 15. In this case, the input range and adjustment range of the voltage controlled amplifier 15 are the ones provided with a margin capable of sufficiently covering the element dispersion of the FM demodulation circuit block 11, the low-pass filter 13 and the equalizer 14.  Thus, this frequency demodulation circuit capable of absorbing the fluctuation of the output current caused by the element dispersion with less jitter noise of the low band is realized by using a current source with less noise.

Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing apparatus and method for obtaining a continuously quality stabilized ceramics based cylinder while a core pipe can be replaced without stopping a sheet-making felt (a water permeable belt). SOLUTION: A core pipe 70 of which both ends are held by a clamp part is allowed to stand by at a position not in contact with and slightly apart from an endless water-permeable belt 52 at position B.
