    • Coaxial cables can connect both apparatus which are provided inside and outside a closed space without opening a through hole and a gap into a wall and door. In a coupling apparatus for connecting coaxial cables each other through a dielectric plate, there are provided a pair of central electrodes which are respectively connected central conductors of the coaxial cables, an inductor which is connected between at least one of the central conductor and the central electrode, and a pair of outer electrodes which oppose each other through the dielectric plate and surround the central electrodes, respectively, and each of which is connected to each of the outer electrodes. It is possible to connect the coaxial cables through the dielectric (glass) plate.

    • A coupling device for coaxial cable which can maintain coaxial transmission mode of low loss is provided. In the coaxial cable coupling device of the capacitor coupling type, in the case where center conductor coupling electrodes for connecting between center conductors of the coaxial cables and external conductor coupling electrodes for connecting between external conductors are used, electric length of the external conductor coupling electrode is set to length of substantially one fourth (1/4) wavelength, or length of multiple of odd number of substantially one fourth (1/4) wavelength of a passing signal. Thus, transmission by the coaxial transmission mode is carried out at an extremely low loss.

    • A fiber retaining structure is disclosed for readily and reliably mounting and retaining optical fibers on a casing in which a light-emitting element and a light-receiving element are incorporated. The fiber retaining structure includes a first link 61 for moving both a second link 26 for crashing O-rings with optical fibers 2 and 3 inserted therethrough against a casing 24 in which a light-emitting element 6 and a light-receiving element 7 are incorporated and holders 27 and 28 for holding the optical fibers when a lever 29 is pushed down, and a spring material. Since the inner diameter of a sealing material for sealing a gap around the optical fiber is set substantially equal to the outer diameter of the optical fiber and since the holding of the optical fibers by the entire holders is performed separately, the distal ends of the optical fibers can be readily and reliably brought into abutment with the light-emitting element and the light-receiving element and the optical fibers can be reliably retained.

    • This invention relates to a photoelectric switch and a photoelectric detector for detecting the presence or absence of an object by using a light, and more particularly to prevention of mutual interference in the case of using a plurality of photoelectric switches. For example, an LED in a light emitting unit intermittently emits a sensing light at the timing of an output pulse from a pulse generator. The resultant pulse is divided in frequency by a frequency divider and then delayed by a one-shot circuit. At the timing of an output pulse from the one-shot circuit, another LED emits a transmission light to a photoelectric switch at next stage. Therefore, the transmission light is always delayed from the sensing light. The transmission light from the preceding photoelectric switch of the same construction is received by a photodiode, and an output pulse is outputted from a pulse generator in synchronism with a synch timing signal produced from the light receiving unit. Thus, the sensing lights from the respective photoelectric switches are emitted at the timings shifted from one another through delays effected by the one-shot circuits.
    • 本发明涉及光电开关和光电检测器,用于通过使用光来检测物体的存在或不存在,更具体地,涉及在使用多个光电开关的情况下防止相互干扰。 例如,发光单元中的LED在来自脉冲发生器的输出脉冲的定时间歇地发出感测光。 所得脉冲由分频器分频,然后由单触发电路延迟。 在来自单触发电路的输出脉冲的定时,另一LED在下一阶段向光电开关发射透射光。 因此,传输光总是从感测光延迟。 来自同一结构的前一光电开关的透射光由光电二极管接收,并且与由光接收单元产生的同步定时信号同步地从脉冲发生器输出输出脉冲。 因此,来自相应光电开关的感测光在通过由单触发电路实现的延迟之间彼此偏移的定时发射。
