摘要： PURPOSE:To reduce voltage of a power source for starting electric discharge by providing an auxiliary electrode for starting electric discharge on an outer wall of a luminous tube or an outer wall of an outer tube. CONSTITUTION:A changeover switch 11 connected with a metal vapor discharge tube so as to turn on a high tension power source 12 side of the discharge tube for starting electric discharge. The aforesaid high tension power source supplies 600V, 1A for the electric discharge tube. When high tension is supplied from a triggering power source 13 for generating high tension due to a piezo-electric element, etc., to an auxiliary electrode 14 for starting discharge wound ring-shaped around the outside of the discharge tube, xenon gas contained in the luminous tube 1 causes instantaneous discharge to be effected. Then, glow discharge is started from the power source 12 for starting discharge. When the discharge changes to arcing, a changeover switch 11 is changed over to a normally discharging power souce 10 side providing DC 200V, 1A. The changeover switch 11 uses a timer for 2 to 10sec.

摘要： PURPOSE:To elevate the integration without degrading characteristics such as sensitivity and S/N ratio by arranging one source in common to a plurality of ion selection sensitive film to increase the integration of an ISFET with a reduced ratio of the source area to the total area. CONSTITUTION:A common source 2 and drains 11-14 are formed on a P type Si substrate and an SiO2 film 3 and an Si3N4 film 4 are attached thereon to make an insulator, on which Na selection sensitive film 31, a K selection sensitive film 32, a Co selection sensitive film 33 and a Cl selection sensitive film 34 are formed. In other words, the source 3 is arranged in common to reduce the ratio thereof 2 to the total area thereby elevating the sensitivity with an higher area ratio of the sensitive films 31-34. In addition, drains 11-14 of individual sesitive sections are arranged between a part of the common source 2 to improve the shield effect and the S/N ratio.

摘要： PURPOSE:To make automatic correction of drift possible, by storing the input of an array type photodetector when a control liquid is passed into a flow cell, then calculating and displaying the difference of the input from the input when a sample is passed, and, on the other hand, renewing the storage through discriminating a subsequent control liquid. CONSTITUTION:Light from a light source 1 is passed through a condenser lens 2, and is transmitted through a flow cell 3. An array type photodetector 6 is arranged at the position of image-formation of the spectrum generated by a spectroscope composed of an incidence slit 4 and a concave diffraction grating 5. The signal outputted by the photodetector 6 is amplified by an amplifier 7, stored and calculated by a microcomputer 8 to display on a display 9 as spectrum. That is, since the computer 8 serves to discriminate whether the signal is the control signal or not, to store and renew the control signal, to calculate the ratio of the sample signal to the control signal, or the difference between them, and to display the output, it makes automatic correction of the drift possible, in spite of its mode of single beam.

摘要： PROBLEM TO BE SOLVED: To provide a noiseproofing sidewall for a current collector which provides high assembling precision, hardly requires straightening to provide fine workability, attains reduction in weight, and reduces the manufacturing cost, and to provide a method for manufacturing for the noiseproofing sidewall and a railcar, using the noiseproofing sidewall. SOLUTION: The noiseproofing sidewalls 3a and 3b for the current collector are made out of an extrusion hollow material 20 as a main member that is consituted of two face plates and a plurality of connection plates connecting the face plates. A railcar 1 has the noiseproofing sidewalls 3a and 3b for the current collector that are disposed on both sides in the car-width direction of a roof structure 1a, in correspondence with a pantograph 2 disposed on the roof structure 1a. The noiseproofing sidewalls 3a and 3b can be manufactured, by alternately cutting sidewalls from among the elongated extrusion hollow material 20 in sequence along the longitudinal direction of the material 20. At traveling of the railcar, by allowing airflow to pass through the cavities formed of the face plates and connection plates inside the cutting sidewalls 3a and 3b, aerodynamic noises generated from the sidewalls themselves are restrained.
