Title: Thin-film magnetic head assembly
Inventor: NAGATA YUJI
IPC: G11B5/31
Filed: 1989-06-14
Abstract: PURPOSE:To dispose magnetic gaps in proximity and to facilitate the connection to an outside part by forming a space without disposing two regions for forming electrode terminals face to face and combining head bodies in such a manner that the surfaces formed with thin films are disposed face to face. CONSTITUTION:The simple body 10 of the thin-film magnetic head is partly notched in the region opposite to the region formed with thin-film electromagnetic converting elements. The electrode terminals 5 to 8 connected to external circuits are formed in the region remaining after the notching. The parts formed with the terminals do not face each other and the space is formed if an assembly 20 is formed by combining these head bodies 10 in such a manner that the surfaces 2 formed with the thin films are disposed face to face. As a result, the magnetic gaps to execute the adequate sliding contact with magnetic media and good recording and reproducing are combined in extreme proximity to each other. In addition, the region formed with the electrode terminals is formed with the space and is opened and, therefore, the connection to the external circuits is extremely facilitated.

Title: Pulse width modulation amplifier
Inventor: TSUJISHITA MASAHIRO
IPC: H03F3/217
Filed: 1990-06-11
Abstract: PURPOSE:To obtain a demodulation output without being gripped even against an input signal such as a music signal whose instantaneous voltage is large by providing a level detection circuit, a preamplifier circuit and a power voltage variable circuit. CONSTITUTION:A modulation circuit 16 applies pulse width modulation to an input signal and a demodulation circuit (low pass filter 7) obtains a demodulation output from a modulation signal subject to pulse width modulation at the modulation circuit 16. A level detection circuit 18 detects an instantaneous value of the input signal or an instantaneous value of an output signal of the demodulation circuit and the gain of a preamplifier circuit 15 varies with an output level of the level detection circuit 18. A power voltage variable circuit 17 changes a power voltage to output stage elements (FETs 5,6) of the modulation circuit 16 in response to the output level of the level detection circuit 18. Thus, the input signal such as the music signal is not relatively increased more than a carrier signal of the modulation circuit 16. Thus, the demodulation output is not gripped, the distortion factor of the demodulation output is reduced and a voice signal with high accuracy is outputted.

Patent JP-S5483866-A (JP)
Title: Level detector
Inventor: SHIOTANI ZENKEI
IPC: H03K5/19
Filed: 1977-12-16
Abstract: PURPOSE: To make it possible to accurately detect the level even for a low input by using two square wave converters, which are operative to generate signals in accordance with the level an laternate input electricity, and two timers thereby to effect the direct conversion of the square waves without rectifying the input.  
     CONSTITUTION: A square wave converter 7 generates signals at level 1, when the level of the positive half wave of an input waveform Vi is higher than a reference level VL 1 , and singals at level 0 when the former is lower than the latter. A square wave converter 8 generates signals at 1, when the level of the negative half wave of the input waveform Vi is lower than reference level VL 2 , and signals at level 0 when the former is higher than the latter. A timer 9 judges the time, for which the output of the converter 7 generates the signals at level 1, whereas a timer 10 judges the time, for which the converter 8 generates the signals at level 1. By judging the time for which the outputs of the both timers 9 and 10 are the signals at level 0, it is possible to accurately detect the level even for a low input without responding to the high frequency input higher than a preset frequency.

Abstract: PURPOSE: To apply mutually different press-contact forces on a presser foot part by providing a constitutive section for guiding a spring and an adjusting means for setting a plurality of spring lengths specified to the spring according to the sewing operation of a sewing machine. CONSTITUTION: When operating buttons 42 and 42' are pressed at their operating positions, a plunger 29 is moved through a shaft 26 to the deepest position thereof so that a compression spring 41 has the minimum spring length thereof and a holding foot part 3 or feeding foot part 2 is pressed on a workpiece by the maximum force. When the operating button 42 is moved to its non- operating position, in a cylinder chamber 18, compressed air is not energized any more. A piston 25 is pressed until being abutted to the lower surface of a shaft 21 at the deepest position thereof by the unfastened compression spring 41, and the spring 41 has the maximum length. In this case, a presser is pressed on the workpiece by the smaller force. When both the operating buttons 42 and 42' come to their non-operating positions, the compression spring 41 has the maximum spring length thereof.  Thus, the presser is pressed on the workpiece by the minimum force.

Title: Solid-state image sensing device
Inventor: AKIMOTO HAJIME
IPC: H04N5/335
Filed: 1988-06-22
Abstract: PURPOSE:To inhibit the generation of a leakage current in signal conductors by a method wherein MOS transistor switches are formed in a semiconductor provided on an insulator on a semiconductor substrate and another MOS transistor switches are formed in the substrate in series to these MOS transistor switches. CONSTITUTION:A signal charge is inputted from a wiring 24 connected to a vertical signal conductor 510 and when gates 20 and 23 are opened, the signal charge is outputted from a wiring 26 connected to a horizontal signal conductor 26. As a drain 22 of a MOS transistor switch 516 or 518 is separated from an Si substrate by a thick insulating film 13, its parasitic capacity is far smaller than that of a drain 19 of a MOS transistor switch 515 or 517 provided in a normal Si substrate. Accordingly, the capacity, which parasitizes the signal conductor 526 and the wire 26 at a time when the gates 20 and 23 are both closed, can be reduced.

Title: Manufacture of semiconductor device

IPC: H01L27/08
Filed: 1985-07-12
Abstract: PURPOSE:To prevent the latch up phenomenon by a method wherein a barrier layer is formed by separaring a PN junction section between a P-type epitaxial layer and an N-type semiconductor with an nitride layer and an N<+> diffusion layer. CONSTITUTION:A thermal oxidation film 2 is grown on an N-type semiconductor substrate 1 and is patterned to be etched. Then, a hole opening section is formed on the N-type substrate 1, and a nitride film 4 is grown on it as an insulating film. The nitride film 4 is partially etched, and a p-type epitaxial layer 5 is grown in the hole opening section. Then, the thermal oxide film 2 and the nitride film 4 are removed by wet etching. However, the nitride film 4 within the N-type semiconductor substrate 1 remains without being etched so as to act as a favorable element separation film. With such manufacture method, the process for well diffusion is dispensed with, providing a low cost, more integrated semiconductor device without malfunction such as latch up.

     CONSTITUTION: Gas containing acid gas such as H 2 S and CO 2  is introduced into the area A of a multi-stage gas/liquid counter current contact device 1 as shown by 8. After a part thereof is consumed to produce acid salt in the area A, the gas is sent in sequence to areas B and C with higher absorbing capacity of acid gas via a pertition 2 to remove the acid gas by absorption almost completely. In the water cleaning area D, a small amount of alkali component is removed by water, and then, the gas is discharged. On the other hand, after the acid gas is absorbed by an alkali liquid in the area C, the alkali liquid turned to normal salt it sent to the area b via a pertition 2'. In this manner, the identical reaction is repeated. Subsequently, the liquid is sent to the area A and a thick acid salt liquid thus formed is transferred to a storage tank, as shown by 9. After upper layer of polymer by-products is removed as shown by 20, a part of the liquid containing acid salt in the lower layer is distributed to distribution pipes 14, 14' and 14" via a piping 13 and intrduced into the respective reaction areas.
