    Notes: Several excellent devices have recently been developed to precisely record mandibular movement. However, these devices are not always suitable for use under certain conditions, such as during sleep, because they incorporate a face bow unit. We report here a newly developed, easy and convenient recording device that does not require the use of an instrument within the mouth. Instead, a subminiature pressure transducer is inserted between the outer surface of a fixation device in the external auditory meatus and the anterior cutaneous surface of the external auditory meatus. The fixation device was made using silicone impression material in the shape of the inner external auditory meatus. Following moulding, the material was cut in half and the parts were reconnected using a coiled spring. This method is based on a routine clinical method for palpating the external auditory meatus to observe condylar head movement. By comparing the results obtained using this device with those obtained using CADIAX, we confirmed that it is useful for recording the movement of the condylar head in routine clinical examinations.

    Description / Table of Contents: Résumé De 1966 à 1977, 27 malades présentant une cyphose pottique sévère ont été traités à l'Hôpital National de Murayama. La correction chirurgicale de la cyphose tuberculeuse consiste en un curetage du foyer associé à une ostéotomie vertébrale antérieure. Ensuite la correction progressive est obtenue à l'aide d'un appareil distracteur halo-pelvien, qui permet également la fusion vertébrale. Les indications de cette méthode dépendent de l'âge du malade; du degré de la cyphose et de la présence de lésions associées. Les détails de la conduite post-opératoire sont précisés, en insistant sur leur importance. Les principaux dangers de la correction sont discutés pour lesquels on préconise un certain nombre de précautions.
    Notes: Summary Twenty-seven patients with severe tuberculous kyphosis have been treated at the National Murayama Hospital between 1966 and 1977. We have undertaken curettage of the foci and vertebral osteotomy through an anterior approach, followed by gradual correction with a halo pelvic distraction apparatus and subsequent vertebral fusion. Choice of this method depends upon the age of the patient, the degree of kyphosis before correction, and the presence of concomitant lesions. Details of postoperative management are given and their importance is emphasized. The major risks of correction are discussed and precautions suggested.

    Notes: [Auszug] The proportion of kojibiose in the sources was very small. Moreover, the separation of kojibiose from other disaccharides, especially somaltose, by preliminary carbon column chromatography, was very difficult, as was its synthesis. This communication deals with the preparation of kojibiose. ...

    Notes: Abstract The early phases of three flares, observed by the Nobeyama Radio Heliograph, are studied. Nonthermal and thermal radio sources are identified by comparison with soft X-ray images taken by the Soft X-ray Telescope onboard the Yohkoh satellite. Two of the flares are mainly of nonthermal origin and their location coincides with one of the footpoints of soft X-ray loops. Another flare has both thermal and nonthermal components which start to brighten simultaneously. This suggests that particle acceleration and plasma compression develop simultaneously.

    Notes: Abstract The Hard X-ray Telescope (HXT) is a Fourier-synthesis imager; a set of spatially-modulated photon count data are taken from 64 independent subcollimators and are Fourier-transformed into an image by using procedures such as the maximum entropy method (MEM) or CLEAN. The HXT takes images of solar flares simultaneously in four energy bands, nominally 15 (or 19)–24, 24–35, 35–57, and 57–100 keV, with an ultimate angular resolution as fine as ∼ 5 arc sec and a time resolution 0.5 s. Each subcollimator has a field of view wider than the solar disk. The total effective area of the collimator/detector system reaches ∼ 70 cm2, about one order of magnitude larger than that of the HINOTORI hard X-ray imager. Thanks to these improvements, HXT will for the first time enable us to take images of flares at photon energies above ∼ 30 keV. These higher-energy images will be compared with lower-energy ones, giving clues to the understanding of nonthermal processes in solar flares, i.e., the acceleration and confinement of energetic electrons. It is of particular importance to specify the acceleration site with regard to the magnetic field figuration in a flaring region, which will be achieved by collaborative observations between HXT and the Soft X-ray Telescope on board the same mission.

    Notes: Abstract Using microwave observations made with the Nobeyama radioheliograph (λ=1.76 cm), we have studied temporal variations of sunspot-associated sources in the circularly polarized component. For all three cases of well-developed and rather stable sunspots we found nearly harmonic oscillations with periods in a range of 120–220 s. In one case of an unstable and quickly devolving active region, the fluctuations appear to be irregular with no dominant period. Sunspot-associated solar radio sources are known to be generated by cyclotron radiation of thermal electrons in magnetic tubes of sunspots at the level of the lower solar corona or chromosphere–corona transition region (CCTR). At the wavelength of 1.76 cm, the polarized emission arises in a layer where the magnetic field is B=2000 G (assuming the emission generated at the third harmonic of electron gyrofrequency). We suggest that the observed effect is a manifestation of the well-known 3-min oscillations observed in the chromosphere and photosphere above sunspots. The observed effects are believed to be a result of resonance oscillation of MHD waves inside a magnetic tube. Radio observations of this phenomenon open a new tool for studying regions of reflection of MHD waves near CCTR level. The method is very sensitive both to the height of the CCTR and magnetic fields above sunspots. Thus, detection of oscillations of the height of the transition region even with an amplitude of a few km are possible. The use of a spectrum of one of the observed sources obtained with the radio telescope RATAN-600 allows us to conclude that oscillations in magnetic field strength of about 4 G could be responsible for the effect and are reliably registered. The appearance of the famous 5-min oscillations in the solar atmosphere was also registered in some spectra of radio oscillations.
