Abstract: PURPOSE:To enhance the characteristics of a semiconductor device by a method wherein the outer conductivity type polysilicon is deposited on a semiconductor substrate 11 in an electrode leading-out hole of an oxide film formed on one conductivity type semiconductor substrate so as to form an electrode and then the polysilicon as well as the semiconductor substrate is rapidly heated and quenched by lamp heating process so as to shallowly diffuse the other conductivity type impurities in the part near the substrate of the semiconductor substrate. CONSTITUTION:Polysilicon doped with P type impurities is deposited on a semiconductor substrate 8 in an electrode leading-out hole 9a to form a polysilicon electrode 10. At this time, natural oxide films 11 are thinly deposited on the semiconductor substrate 8 in the electrode leading-out hole 9a since the semiconductor substrate 8 is once exposed to the atmosphere in transit. Thus, the polysilicon electrode 10 is formed on the natural oxide films 11 in the phase of vapor deposition. Accordingly, after the deposition of the polysilicon, the polysilicon electrode 10 as well as the semiconductor substrate 8 are heat-treated by a lamp heating device. Through these procedures, the P type abundant impurities in the polysilicon are moved within a short time by the lamp heating process featured by rapid rising and lowering of the temperature so that the natural oxide films 11 may be broken down to be diffused in the semiconductor substrate 8 forming a shallow P type region (imputy region) 13.

Title: Demodulating circuit
Inventor: SUZUKI TOSHIROU
IPC: H03H11/04
Filed: 1977-09-22
Abstract: PURPOSE: To obtain a demodulating circuit featuring the low distortion property for modulation of the pulse amplified modulation wave, by connecting the sampling  output to the negative side input of the operational amplifier via the resistance, by  grounding the positive side input, and connecting  the low pass filter between the n egative side input and the output respectively.  
     CONSTITUTION: The input signal is sampled through analog resampling switch 1 and then put into reverse-phase input terminal 9 of operational amplifier 5 via resistance R 1 . Low pass circuit 6' is connected between terminal 9 and output terminal 8, and  positive side input terminal 7 of amplifier 5 is earthed. As terminal 7 is at the earth  potential, no inphase input exists in amplifier 5 and thus the even-orde higher  harmonic distortion can be suppressed. Capacitor C 3  is provided against the distortion caused by the through rate, and amplifier 5 is actuated as an imperfect intergrator. Amplifier 5 showns a low gain to the rise waveform featuring a higher-speed  time constant than the time costant obtained with capacitor C 3  plus resistance R 2 ,  and R 3  thus reducing occurrence of the unnecessary higher harmonic distortion

Each dielectric part 16 is formed so as to project from the plane of the conductive part 15a. The dielectric parts 16 are formed like islands on the surface of a conductive base body 15A. The surface of the conductive base body 15A acts as the conductive part 15a for the dielectric parts 16. When the obtd. developing roller 15 is used, clogging of a toner is hardly caused because the dielectric parts 16 are formed in projecting shape, which prevents the toner from scattering. Thus, soiling by the toner in the machine can be prevented.

Title: Simple sound reproducing machine having external output shaft
Inventor: KOIKE SHIGEMORO
IPC: G11B3/00
Filed: 1983-06-24
Abstract: PURPOSE:To execute other operation automatically after the reproducing operation of sound record by moving a center shaft supporting a record disc in the axial direction to disconnect power transmission from a driving motor for the record disc to an external output shaft. CONSTITUTION:When a start bar 11 is pushed, a pickup 6 is restored to the reproducing start point (a) of the record disc 3. When the start bar 11 is released, stylus pressure is applied to the pickup 6. If a switch is turned on under said state, the motor 9 is driven, the record disc 3 is rotated and the record is reproduced. At that time, a driving wheel 14 is released from a driven wheel 15, so that power is not transmitted to an external output shaft 12. When the pickup 6 reaches a reproducing end point 3b and falls into a stylus drop recessed part (d), the center shaft 2 is moved upwards by the force of a stylus pressure spring 10. Consequently, the driving wheel 14 is meshed with the driven wheel 15 and the power of the motor 9 is transmitted to the external output shaft 12. Thus, other operation is automatically executed successively to the reproducing of the sound record.
