Patent JP-S5661818-A (JP)
Title: Sine wave oscillator
Inventor: UCHIUMI TAIKI
IPC: H03H11/24
Filed: 1979-10-25
Abstract: PURPOSE:To satisfy at one time both the waveform distortion and the stability of the sine wave oscillator, by just adding one unit of the EFT to the conventional circuit using the Wien bridge. CONSTITUTION:The EFT10 having the same property as the FET5 is connected in series between the resistance 4 and the FET5, and the polarity of the drain source of the FET10 is made opposite to that of the FET5. At the same time, a short circuit is given between the gate and the source of the FET10. Thus the voltage VGS between the gate and the source is set to zero for the FET10 and the value near zero for the FET5 each for operation. In this case, the resistance between the source and the drain becomes constant at all times regardless of the level or the polarity of the drain-source voltage VDS. In other words, the resistance has a linear change to the change of VDS over a wide range. Thus a linear element is obtained. As a result, an oscillator which satisfies at one time both the waveform distortion and the stability can be formed. The same effect is secured if the FET5 and 10 are connected in reverse parallel.

Filed: 1989-05-31
Abstract: PURPOSE:To eliminate turbulence of an optical signal and damage due to the deformation of an optical fiber by providing a protecting pipe, integrally embedded along a lengthwise direction in the interior of a hose, and the optical fiber inserted without being fixed in the pipe. CONSTITUTION:A hose 1 is formed of vulcanized rubber and plastic or thermo- plastic elastomer, further a reinforced layer 3, in which a reinforcing thread or the like is stranded or wound, may be provided in the interior of the hose 1. A protecting pipe 4 can be also formed by a material similar to the hose 1, but it is preferable to provide hardness and strength possible to protect an optical fiber 5 from external and internal pressures. The protecting pipe 4 is linearly or helically embedded along a lengthwise direction in the hose 1. The protecting pipe 4 is integrally fixed to the hose 1, but the optical fiber 5 is not integrally fixed to the hose 1. Accordingly, since tensile and compressive loads of the optical fiber can be suppressed for flexing and extension-contraction of the hose, misoperation by turbulence of an optical signal and damage of the optical fiber can be eliminated.

IPC: D01G1/08
Filed: 1980-10-03
Abstract: PURPOSE: To stretch-break a filamentary yarn stably and uniformly even at a high speed, by bending both edges of an apron in the width direction at the yarn holding part of the apron wound around stretch-breaking rollers to the yarn holding surface part.  
     CONSTITUTION: In winding aprons 10 and 10' around stretch-breaking rollers 8 and 8', both edges 11 and 11' in the width direction of the apron 10 are bent to the yarn holding surface side between an apron tensioning roller 7 and the stretch- breaking roller 8. For bending both edges of the apron 10 in the width direction, auxiliary rollers 9 and 9' or guides are titled and mounted thereon. A filamentary yarn 2 in the stretch-breaking zone is enclosed almost by the aprons 10 and 10', and an accompanying air current caused by the aprons 10 and 10' is also trapped. Thus, the turbulence of the filamentary yarn 2 will not occur easily, and the filamentary yarn 2 can be stretch-boken uniformly even at a high speed ≥200m/ min.

Title: Method and apparatus for preparing emulsion fluid
Inventor: ARAKI TOSHIO
IPC: B01F25/74
Filed: 1981-09-03
Abstract: PURPOSE:To obtain an extremely stable emulsion fluid, by a method wherein a stock fluid is injected from the gap groove between fine orifices of a rotor and violently collided against a mixed, stirred and rotated particulate in the outside of the rotor to be ground into an extremely fine powder. CONSTITUTION:By the centrifugal force action of a rotor 7 rotated at an ultra- high speed, a stock fluid is injected to the outside from the fine orifieces 10 of said rotor 7. The stock fluid pressed to the inner wall of the rotor 7 by this action is instantaneously expanded by vacuum action generated by synergistic effect of friction resistance due to pressure introduction at the inlet of the fine orifice 10 of the rotor and the injection pressure of the fluid from the fine orifice 10 to form obstacle bodies 15. By this mechanism, centrifugal force and pressure stream detecting effect are increased and the stock fluid is injected from the fine orifice 10 to be violently collided against the rotary fluid present between protrusions 11, 12 to receive ultra-fine grinding action. By this method, an extremely stable emulsion fluid is obtained.
