Abstract: PURPOSE:To prevent the dielectric breakdown of a gate insulating film in the manufacture of a semiconductor device by a method wherein, in the state in which a semiconductor film or a metal film is grounded, desired impurities are ion-implanted in a semiconductor substrate through the intermediary of the semiconductor film or the metal film. CONSTITUTION:After field oxide films 2a and 2b have been formed on a P type Si substrate 1, gate oxide films 3 and 4 are formed only on the part other than the expected region where source and drain regions will be formed. A semiconductor film or a metal film 8 is then formed on the surface of the substrate 1. Then in the state wherein said film 8 is grounded, the P charged with positive electricity is injected into the substrate 1 by projecting an Si ion beam 7 through the intermediary of the film 8. Subsequently, an annealing is performed in a nitrogen atmosphere, and an N type source region and a drain region 6 are formed. Then, the film 8 is removed by etching, a P-glass film 10 is formed on the substrate 1, and contact holes 11a, 11b and 11c are provided. Then, a heat treatment is performed on the substrate 1, a film 10 is liquefied, Al is adhered to the hole 11a and the like, and a contact 13a and the like are formed.

Abstract: PURPOSE:To ensure the stable rotation control, by controlling the revolution of a spindle with a reproduced signals obtained via a mixing circuit and a low pass filter (LPF) and a frequency difference signal between a synchronizing bit clock and a reference signal. CONSTITUTION:A stable bit clock synchronous with a reproduced signal is detected by a PLL3, and a difference frequency signal between the bit clock frequency and a reference frequency of a frequency lower than said bit clock frequency is generated via a mixing circuit 9 and an LPF10. This difference frequency signal is turned into a rough control signal. Then a spindle motor 17 is controlled via a frequency-voltage converting circuit 11, the 2nd level adjusting circuit 12, an analog switch 14, a DC amplifier 15, etc. The sensitivity coefficient due to the circuit 9 and the LPF10, etc. increases substantially by the rough control signal having a low frequency. Thus it is not needed to set the amplifier 15 at a high gain, and the rotation control is stabilized.

Title: Output switching circuit
Inventor: TOKUDA KAZUO
IPC: H03K17/60
Filed: 1984-08-06
Abstract: PURPOSE:To attain the external control of an output current as well as formation of an IC by combining two constant current circuits. CONSTITUTION:The base of a transistor (TR) 23 is connected to the collector at one side of a TR25 corresponding to a constant current circuit 1. A TR27 is driven by a switching circuit 21 connected to the base of the TR27 and flows a current I27 to the collector. Then a current I25 corresponding to the I27 flows to the base of the TR23. While the collector at one side of a TR29 corresponding to a constant current circuit 2 is connected to the base of the TR25. The collector at the other side of the TR29 is connected to its base and then to the collector of a TR30. A current I30 decided by the DC voltage impressed to an input terminal 32 flows to the collector of the TR30. Then an output current I29 corresponding to the I30 is flowed through the collector at one side of the TR29. Therefore a current I29 is flowed to the terminal 32 after impression of the voltage in a state where the TR23 conducts with flowing of currents I25 and I27. Thus the I25 changes in proportion to the change of the I30. Then the response speed of a switching circuit can be controlled by having a time constant for the change of the input voltage when the TR23 is cut off.

Title: High-density recording disk reproducer
Inventor: HIROTA YUTAKA
IPC: H03L7/14
Filed: 1982-09-20
Abstract: PURPOSE:To prevent extraction of a wrong clock due to a dropout, by holding the time constant of a PLL (phase locked loop) circuit at a prescribed value when a dropout is produced. CONSTITUTION:A switch SW is closed in a normal reproduction time, and a PLL circuit responds to an input signal with a normal time constant which is decided by a resistance R and the 1st capacitor C1 and can extract a correct clock. If a dropout is generated, the SW is opened and the loop of the PLL circuit is opened. In this case, the 2nd capacitor C2 is charged with the electric charge equivalent to the output of the 1st operational amplifier 5 which is obtained before generation of the dropout. Therefore, the both-terminal voltage of the C2 is delivered to an output terminal B to actuate a voltage control oscillator 3. Thus it is possible to prevent generation of a clock which is extremely erroneous even after generation of a dropout. This device can prevent extraction of a wrong clock due to a dropout.

Title: Magnetic reproducing device, magnetic recording and reproducing device, and editing device
Inventor: KOBAYASHI NOBUO
IPC: G11B27/02
Filed: 1994-07-18
Abstract: PURPOSE:To perform high-grade consecutive recording and editing which need no mechanical phase-adjusting function by the use of two-head digital audio tape recorders. CONSTITUTION:Two magnetic recording/reproducing devices are connected for recording and reproducing. When a consecutive recording instruction is given to the recording side, the consecutive recording control means 48 instructs the tape travel control means 45 to start the reproduction of the consecutive recording tape a little in advance of the consecutive recording connection point and reads the tape time code. At the same time, it takes out the reproduced output for monitoring from the pre-recorded memory means 42 in advance of the time code of the tape by a specified interval of time required for correcting the delay occurring in the digital signal processing means 41. When the output reproduced from the memory reaches the position corresponding to the consecutive recording connection point, the consecutive recording control means 48 sets the recording mode on the recording side and issues a memory reproduction starting instruction to the reproducing side, which actuates the reproducing function immediately after the connection point and inputs the tape data accumulated in the memory means 42 to the recording side as reproduced output.

Filed: 1980-11-26
Abstract: PURPOSE:To eliminate malfunction by recording a low-frequency signal on an audio-frequency recording part and by performing a program search when the low-frequency signal is not detected during fast-forwarding or rewinding operation. CONSTITUTION:During recording on a magnetic tape, a low-frequency signal (<=20Hz) is recorded on an audio-frequency recording part except a no-sound part. The output of a reproducing heat 1 is sent to a speaker 5 through a preamplifying circuit 2, a high-pass filter 3, and an amplifier 4 to be reproduced. During fast-forwarding or rewinding operation, the output of the preamplifying circuit 2 is passed through a low-pass filter 7, an amplifying circuit 7, a level adjusting circuit 8, and an output inversing circuit 10 to output a program search signal 10 when the low-frequency signal is not inputted. Consequently, program searching operation is carried out adequately all the time without malfunction.

Filed: 1986-07-16
Abstract: PURPOSE:To improve the sound quality of a reproduced sound by superimposing a prescribed noise signal for a period being discriminated to be a silence period. CONSTITUTION:A decoding expansioin section 11 identifies a silence flag FN at the head of an inputted coded data DA and an supplies output to a silece period discrimination section 12.

Thus, a decoded data CD in a block of non-silence period and the noise data DZ in the block of silence period are fed from, the selector 13 to a digital/analog converter 18 as the sound data SD. Thus, the unnaturality in the, audible sense is by superimposing a prescribed noise signal of small amplitude onto the reproduced sound signal in the period discriminated to be a silence period to improve the sound quality of the reproduced sound.
