摘要： PURPOSE:To obtain airtightness by inserting an optical fiber into the insertion hole of a holding member fixed through a vessel wall and packing a packing material around a coated fiber formed in this insertion hole. CONSTITUTION:The elastic member 10 comes into tight contact with the outer peripheral surface of the optical fiber 3a and the coated optical fiber 3c and the inner peripheral surface of the insertion hole 9 of the holding member 8 when a bolt 11 is screwed to the internal threads at the atm. side B end of the insertion hole 9 of the holding member 8 and the elastic member 10 is compressed. Since the elastic member 10 is in tight contact with the coated optical fiber 3c and the holding member 8, the airtightness between the holding member 8 and the optical fiber 3c is assured. The high airtightness is maintained in this way.

摘要： PURPOSE:To reduce errors without requiring detection in a wide wavelength range for a photo detector, by providing a reflecting film adapted to transmit signal lights while reflecting reference light between material and a fiber for transmitting and receiving light with the wavelength of the reference light smaller than that of the signal light. CONSTITUTION:Emission lights from LEDs 2 and 3 driven by a drive section 1 are combined 4 and introduced into material 8 by way of a fiber 7 for transmitting and receiving light passing through a distributor 5. A reflecting film 12 varying in the reflectance depending on the wavelength is provided on the LED side of the material 8. The characteristic of the film 12 is such that the absorption end thereof is positioned right on the low wavelength side of the signal light. The reference light is reflected mostly on the surface of the material 8 and all passing through the film 12 is absorbed as passing through the material 8. Light from an LED 3 for signal lights mostly passes through the reflecting film 12 and is reflected on a reflection mirror 9 to make it proper in the temperature transmission level so that it allows the light to pass through the fiber 7 together with the reference light to be converted into voltage with a photodiode 6 and a light receiving section 10. The resulting signal is compared with the transmission level with respect to the temperature previously memorized with a signal processing section 11, thereby enabling the detection of temperature.

摘要： PURPOSE:To elevate the accuracy with a better S/N ratio, by arranging a photo detector made up of a plurality of photodiodes for detecting several light beams separately to reduce the current running without exposure to light. CONSTITUTION:Outputs of LEDs 2 and 3 driven in a pulse by a drive section 1 are combined 4, introduced through a transmitting fiber 5 to material 7 the transmittance of which varies in terms of function of temperature and the transmission light reaches photodiodes (PD) 82 and 83 through a receiving fiber 6. for example,the current (dark current) running without exposure to light is very small in the same package of the PD 82 mainly composed of In, Ga and As, for instance and, for example, the PD 83 mainly composed of Si is arranged to be connected in parallel. With such an arrangement, light of a long wave side LED is received with the PD 82 while the light of a short wave side LED done with the PD 83 to form a PD acting in a wide wavelength range with limited dark current. The voltage converted with the PD 8 is compared with the quantity of light transmitted for the temperature memorized in a processing circuit 9, thereby enabling the measurement of the temperature of the material 7.

摘要： PURPOSE:To make it possible to certainly operate a trouble detecting circuit even in the event of any trouble, by a method wherein a system is triplicated and the logical operation of one system is made reverse to the logical operations of other two systems. CONSTITUTION:Comparison circuits 8a, 8b and a comparison circuit 8c are constituted so as to reverse the output polarities thereof under a same input condition and relay drive circuits 9a, 9b and 9c are respectively operated by these outputs. When the high potential part of electric machinery is charged, relays RLa and RLb are operated by positive voltage outputs from the circuits 8a, 8b and a relay RLc is operated from the negative voltage from the circuit 8c. When it is not charged, the relays RLa, RLb are not operated and the relay RLc is operated. As mentioned above, because relays RLa, RLb, RLc come to operation, operation and unoperation in the case of charging and come to unoperation, unoperation and operation in the case of non-charging, a majority decision treatment circuit 11 decides charging or non-charging in more operations of the triple-system.

摘要： PURPOSE:To obtain a bar code remote reader having a wide reading distance range and a wide application field by irradiating a bar code whose irradiation is positioned by a visual means with reading laser beams from a remote distance through a telephoto optical system. CONSTITUTION:A switching mirror 31 is positioned with a 45 deg. inclination in the optical path of a reading laser beam L1 radiated to a bar code 4A arranged on a remote distance as a target. The image of the bar code 4A is transmitted to a finder 33 through a telephoto optical system 30, the switching mirror 31 and a reflection mirror 32. Thereby an operator can focus the bar code 4A and select the size of the image while positioning an irradiated point by adjusting the optical system 30. Then the mirror 31 is rotated up to an ON state so that the laser beam L1 is made incident upon the optical system 30. At the time, a laser beam L projected from a laser beam generating source 1 oscillates a light deflector 3A in the arrow B direction and the horizontal direction of an object is scanned by the reading laser beam L1.

摘要： PURPOSE:To eliminate the need to make phase adjustments, phase by phase, by inverting one or two phases of a three-phase voltage by a phase inverting circuit and performing vector composition with the remain two or one phase by an adding circuit. CONSTITUTION:When a voltage is applied to respective charging part conductors 2, an electric field is generated to a grounded jacket 1 and electrostatic capacity values CA-CC.

The currents iB and iC of B and C phases are put together into iBC. Then voltages Va1 and Vbc are is further amplified by an amplifier 5, whose output is level-detected, so that a display device 10 makes a charge/ noncharge (whether or not there is a three-phase balanced voltage) display, etc.

摘要： PURPOSE:To measure oscillation with high precision without being affected by electromagnetic induction by varying the magnetic resistance of a magnetic path by the oscillation at a position to be measured and measuring the transmissivity of light which varies according to the variation of the magnetic flux. CONSTITUTION:Magnetic flux from a permanent magnet 12 form the magnetic path passing through a magnetic material 14a, a magnetic sensor 16, a magnetic material 14b, an oscillator 18, and a magnetic material 14c. An oscillator 18 is fitted to a wave oscillator 24 through a leaf spring 20 and a spacer 22 and varies in gap length lb by receiving the oscillation from the oscillated body 24, so the magnetic field at the part of the magnetic sensor 16 varies in intensity according to the oscillation of the oscillator 18. An optical transmitter and receiver 30 irradiates the magnetic sensor 16 which varies the transmissivity of light according to the intensity of the magnetic field with light through an optical fiber 32 and a fiber 34 for photodetection receives transmitted light. This transmitted light corresponds to the intensity of the magnetic field of the magnetic path, i.e. oscillation, which is therefore detected in the form of a light signal.
