Title: Determination system for obstruction point of optical fiber
Inventor: KOBAYASHI IKUTAROU
IPC: G01M11/00
Filed: 1979-03-28
Abstract: PURPOSE:To determine an obstruction point in an optical fiber, where rays of light are not reflected, without providing signal lines between both of terminal measuring instrumenrs, by simultaneously being propagating rays of light with different wavelength to determine the obstruction point in the optical fiber from difference between the times of the interruption of both of optical signals at a light receiving terminal. CONSTITUTION:Pulse rows with different optical wave-length lambda1, lambda2 are formed by optical modulators 31, 32 according to pulse rows put out from a pulse generator 11 and projected to an optical cable fiber 13 through a wave composer 33. As a result, the velocities of optical pulses being propagated through the fiber 13 in response to the wave-length lambda1, lambda2 due to the dispersion characteristics of the fiber 13. Thus, when difference between the arrival times of the pulse light of the wave-length lambda1, lambda2 at the time of the occurrence of obstruction is detected by a wave divider 34, observing units 15, 23 corresponding to the wave-length lambda1, lambda2 of optical pulses and a comparator 26, which are provided at a light receiving terminal, an obstruction point where rays of light are not reflected can also be determined without providing signal lines between both of terminal measuring instruments by operation based on a dispersion rate previously determined by the fiber 13.

Title: Level detector
Inventor: GOTOU KATSUHIKO
IPC: H03M1/36
Filed: 1982-03-10
Abstract: PURPOSE:To attain stable operation even if a level detecting terminal is grounded and to obtain a discriminating output of a desired level, by applying an external control input to the emitter of a PNP transistor (TR) for high level detection. CONSTITUTION:Where Vk is a voltage of a reference voltage source 17, a forward base-to-emitter voltage of a PNP TR15 is Vf15, that of NPN TRs2, 3 is Vf2, Vf3 and V11 is an applied voltage at a terminal 11, the TR2 turns off with Vf2<V11 and turns on at Vf2>V11. A TR15 turns off at V11<Vk+Vf15 and turns on at V11>Vk+Vf15. The TR3 turns on at >=Vf3 of a voltage across a resistor 7, and turns off at <=Vf3. Thus, when the voltage V11 is over (Vk+Vf15+Vf3XR16/R7), (state A' of Fig.), the TRs2, 3 turn on, and when the voltage V11 is less than the said value and over the Vf2, (state B' in Fig.), the TR2 turns on and the TR3 turns off, and when the voltage V11 is less than the Vf2, (state C' in Fig.), the TRs2, 3 are turned off. Even if the terminal 11 is grounded, each  TR is turned off surely to offer stable operation. Then, the level detection of the voltage V11 is done with ''H'', ''L'' of output signals (b), (d) of the TRs2, 3.

Filed: 1989-02-16
Abstract: PURPOSE:To lower the extent of friction torque with an opposite material as well as to prevent a noise from occurring by forming a lubricating slip layer in a partial projecting spherical part on the outer surface of a seal body. CONSTITUTION:A solid lubricant of graphite, molybdenum disulfide or the like and a mixture 5 consisting of a metallic fiber and a resin bonding material charge meshes of a cylindrical reinforced member 1 consisting of a metallic mesh and cover this reinforced member 1 whereby all are formed into compression molding as one body. Then, a through hole 11, where the reinforced member 11 is exposed, is formed in the inner surface and a partial projecting spherical part 12 on the outer surface, respectively. In addition, a lubricating slip layer 7 being formed by a lubricating composition is formed on this partial projecting spherical part 12 at uniform and minute thickness. A seal body 14 formed like this is low in friction torque at the initial stage of friction with the opposite material because the lubricating slip layer 7 is formed on the partial projecting spherical part 12, thus stable performance is brought into full play without emitting any noise for a long period of time.

What is more, even if ionized oxygen gas or inert gas is used in place of ionized nitrogen gas, the same action effect can be gotten. Hereby, it becomes possible to manufacture the semiconductor, which does not cause the deterioration of the breakdown strength of a gate oxide film or the breakdown in an ion implantation process, nor the inferiority resulting from the dust, etc., adhering to the surface of the semiconductor due to static electricity, in the subsequent process.
