Abstract: PURPOSE:To improve reliability, and to obtain stable laser beams by detecting the misalignment of a mirror by oppositely arranging photodetectors while holding an oscillation axis in the direction orthogonal to the direction of the oscillation axis and correcting the misalignment of the mirror. CONSTITUTION:A laser device is constituted in such a manner that internal laser beams 6 are obtained by an unstable type resonator constituted by a concave mirror 1 and a convex mirror 2 oppositely disposed while holding an excitation region 5 and annular output laser beams 7 are outputted to the outside of a vessel 8 through a window 4 by a coupling mirror 3. Photodetectors 9 are arranged oppositely near the mirrors 1, 3 while each holding an oscillation axis in the direction orthogonal to the direction of the oscillation axis. A signal processor 10 outputs signals adjusting the angles of the mirros 1, 2 in the directions that a difference between detecting outputs from the photodetectors 9 oppositely disposed is brought to a predetermined value. An angle regulator 11 changes the angles of the mirrors 1, 2 by the signals.

Title: Method and apparatus for heatttreating filament
Inventor: HAINTSU SHITSUPERUSU
IPC: D02J13/00
Filed: 1977-07-15
Abstract: Compression-crimped synthetic silk consisting of thermoplastic is subjected in thread-plug form to thermal aftertreatment. For this purpose, an aftertreatment drum (14) of adjustable rotational speed and at least one compression chamber (10) are used. A delivery unit (11) of adjustable rotational speed, arranged between the compression chamber or compression chambers and the aftertreatment drum, serves for conveying the thread plug or thread plugs of crimped multifilament synthetic silk, formed in each compression chamber, out of the compression chamber or compression chambers and, after passage through a free zone, towards the aftertreatment drum. Once arrived there, each continuously delivered thread plug runs in an approximately tangential direction onto the gas-permeable casing of the rotating aftertreatment drum cylinder and is transported through the aftertreatment zone by the latter in the form of helical thread-plug turns lying closely to one another and free of radial pressure. The thread material is either heated or cooled. The gaseous treatment medium flows through the helical thread plug turns of the treatment material in the radial direction. The opening of the thread plug or thread plugs to form crimped synthetic threads takes place at the end of the aftertreatment drum. A tension-free, uniform thermal treatment of the synthetic silk delivered at a high feed speed, along with a sufficient dwell time, is made possible in this way. <IMAGE>

Abstract: PURPOSE: To obtain a 3-dimensional pattern input device which picks and supplies optically the uneven pattern on the soft substance such as the rubber stamp, the fingerprint or the like directly and in real time.  
     CONSTITUTION: Full reflection beam A is caused on interface 22 between air 21 and transparent material 20 such as the glass or the like with the incident angle exceeding critical angle Θ 0 , and no full reflection light is caused at the area of the interface where the rubber, the skin and the like adheres owing to the mutual refractive indexes of the media.

And in case the beam enters slope 31c adhered to subject 32 with an incident angle more than the critical angle, the pattern information composed to the full reflection beam and non-full reflection beam can be obtained according to the fingerprint and in the form of emission light 33. This information can be supplied to processor 3 via TV camera 2.

Title: Amplifier for telephone set
Inventor: HISHINUMA ESAO
IPC: H04M1/60
Filed: 1983-05-16
Abstract: PURPOSE:To increase the impedance of an AC output without increasing a DC resistance value of an amplifier for telephone set by adding an AC positive feedback loop to the amplifier circuit. CONSTITUTION:A capacitor 10 and a resistor 11 connected in series are provided between an output side of a voltage current converting circuit 9 and an inverting input terminal (voice signal input terminal) of an operational amplifier circuit 5. As to the AC impedance between terminals T1 and T2, capacitors C1, C2 and C3 are selected as values where the AC output impedance is sufficiently small and negligible, and an AC current iA flowing is expressed as iA=e/R4- e/RAXR3XK=eX(RA-R3XK)/(R4XRA), where eV is an AC voltage applied between the output terminals T1, and T2. Thus, the AC output impedance Zout is reduced to Zout=e/i=R4XRA/(RA-R3XR4XK)=R4/(1-R3XR4XK/RA), and when the resistance value RA of the resister 11 is set to e.g., RA KXR3X R4, the AC output impedance is increased without changing the resistor R4 of the resistor 1.
