    摘要: A gas sensor includes a sensor element having one end portion exposed to gas to be measured. A plurality of electrodes are provided on the other end portion of the sensor element. A plurality of terminal contacts are resiliently held in electrical contact with the electrodes, respectively, in such a manner that the terminal contacts hold the other end portion of the sensor element therebetween. The electrodes are so provided on the sensor element that the terminal contacts abut against the electrodes to prevent the sensor element from being moved axially and laterally.

    摘要: To perform waveform shaping, retiming and amplification of the transmitted pulse signal of a binary PCM fiber optic communication employing an optical pulse signal which has a pulse duty factor within 1 with respect to a time slot, an optical waveform shaping device is proposed in which the optical pulse signal is branched by an optical branch circuit into two optical signals. The one transmitted optical signal passes through a photodetector, a band-pass filter for extracting the fundamental frequency component of the signal, an amplifier and a delay circuit, so that the signal is converted to a sinusoidal voltage synchronized with the optical pulse signal. The other optical signal passes through a semiconductor electrical absorption type optical modulator which is driven by the sinusoidal voltage and a DC voltage, so that the width of a gate waveform is changed by controlling the amplitude of the sinusoidal voltage and the DC voltage.

    摘要: A compound type microscope is provided which can observe the measurement sample of an atomic force microscope (AFM) by means of an optical microscope. This compound type microscope is comprised of an optical microscope having an objective and an observation optical system, a cantilever having a reflecting surface and detecting an atomic force, an irradiating optical system for applying a spotlight to the cantilver, a detector for detecting the displacement of reflected light caused by the displacement of the cantilever, and a sample stage for placing a sample thereon. The arrangement can be designed to accommodate the use of a scanning tunnel type microscope (STM) interchangeably with the AFM so that the sample can be measured by the STM instead of by the AFM. To this end, the probe of the STM can be detachably mountable coaxially with respect to the objective of the optical microscope, whereby the probe of the STM and the cantilever of the AFM can be selectively disposed below the objective.

    摘要: Just before a container is sealed by a container sealing apparatus or a container has a sealing body fed to its narrow-mouth by a sealing body feeder, an inert gas is blown into a head space of the container to replaced air present in the head space, and thereafter the container is immediately sealed or a sealing body is fed thereto to sealingly confine the inert gas within the head space. Preferably prior to the above-mentioned step, a heated gas is fed into the head space of the container which has been filled with a liquid to eliminate bubbles existing within the head space and remove the air trapped in the bubbles by the thermal energy of the heated gas. An apparatus to be used for practicing the above method is also disclosed.

    摘要: A flat coil for use in a rotary electric machine has an annular row of generally radially extending and circumferentially spaced electrically conductive segments (1) on each annular end face of an electrically insulating base member (2). Each segment has a non-effective section disposed adjacent to the radially inner end of the segment and having a mean thickness greater than that of the remaining sections of the segment to improve the cooling ability of the coil. The segments are formed by punching a blank of thin copper sheet to form therein an annular row of radially extending and circumferentially spaced slits to thereby form an annular row of radially extending and circumferentially spaced segments. Before or after the blank is punched, the blank is subjected to forging, electrolytic plating, electrolyzing treatment or mechanical treatment so that the non-effective section of each segment has a thickness greater than that of the remaining sections. Thereafter, the annular row of segments is secured to an annular end face of the annular base member. A similar another annular row of segments is prepared and secured to the other end face of the annular base member. The segments of the two annular rows are then welded at their radially inner and outer ends to form three separate windings of coil around the base member. The annular rows of the segments are then severed along the outer and inner peripheral edges of the rows to separate the segments from the blanks to thereby complete the flat coil.
