    Deep impurity levels and diffusion coefficient of manganese in silicon (1991)

    Notes: Manganese-related deep levels in n- and p-type silicon have been investigated by deep level transient spectroscopy and Hall effect. Two electron traps of Ec−(0.12±0.01) eV and Ec−(0.41±0.01) eV, and a hole trap of Ev+(0.32±0.01) eV are found in manganese-doped silicon. The energy levels of these traps correspond to the transitions between four charge states (Mn−, Mn0, Mn+, Mn++ ) of interstitial manganese. An additional donor-type electron trap of Ec−(0.51±0.02) eV is observed in the n-type samples, and the trap can be tentatively assigned to substitutional manganese. Furthermore, an electron trap of Ec−(0.50±0.02) eV is observed for n+p junction samples diffused with manganese in boron-doped p-type silicon. The trap is attributed to the manganese-boron complex, which is formed owing to the pairing reaction of interstitial manganese and substitutional boron. From the investigation of the pairing reaction, the diffusion coefficient DMn of interstitial manganese is determined in the temperature range 14–90 °C. It can be represented by the expression DMn=2.4×10−3 exp(−0.72/kT)cm2 s−1.

    Notes: We have studied the feasibility of using carbon as a scanning tunneling microscopy tip material for experiments conducted under electrochemical environments. The tips were found to be stable and durable in acidic or alkaline solution for several hours. The fabricated carbon tips were capable of resolving graphite atoms in electrolyte solution under potentiostatic condition as well as in air.

    Electron microscopic studies of Moll's gland cyst (1987)

    Notes: Several Moll's gland cysts from 4 different patients were studied with the light and electron microscopes. The cysts were lined with a combination of several different epithelia, such as completely keralinized epithelium, glycogen-rich, stratified squamous epithelium with incompletely keratinized luminal cells, sweat duct epithelium, and secretory cells. In one case in addition to the above components, secretory-type wall cells contained very large lamellar inclusions which were PAS positive and diastase resistant. It was concluded that Moll's gland cyst is composed of dilated duct of the Moll's gland and secretory segment; the proportion of each segment is variable but the portion showing ductal differentiation is usually predominant and typical secretory epithelium is not always seen.

    Notes: Two patients became infested with Gnathostoma nipponicum after eating raw loach-fish they had caught in a rice field in central Japan. A fragment of Gnathostoma was found in a biopsy from one of them. The sera of both patients reacted with Gnathostoma antigen using indirect immunofluorescence. Scanning electron microscopy was performed on blocks of the paraffin-embedded parasite sample and the viscera of a fish from the same rice field. The risk of eating raw freshwater fish is discussed.

    Biochemical genetic evidence for a hybrid origin of spined loach, Cobitis taenia taenia, in Japan (1994)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: Starch gel electrophoresis and isoelectric focusing were performed on sarcoplasmic proteins from three taxa of cobitid fish in Japan, Cobitis biwae, C. taenia striata and C. l. taenia. These taxa are hardly distinguishable from each other by external appearance or morphological characters. Electrophoretic patterns of sarcoplasmic proteins from white muscle suggested fixed allelic differences between C. biwae and C. t. striata at two protein-coding loci (parvalbumin and creatine kinase). The third taxon, C. t. taenia, showed composite banding patterns with respect to the above two proteins, suggesting C. t, taenia originated from hybridization between C. biwae and C, t. striata. Previously, C. t, taenia and C. t. striata were believed to have shared a common ancestor subsequent to their divergence from C. biwae.

    Palpation as a method for evaluating occlusal discrepancies (1991)

    Notes: In this study, 30 dentists were surveyed about their methods of palpating teeth for the evaluation of premature contacts. Thirty-eight dentists were then tested to determine their ability to discriminate degrees of prematurity using each of two different methods of palpation. The degree of digital pressure used by each dentist during palpation was also measured. The majority of dentists chose the same method for palpation: a single forefinger overlaying the facial surfaces of the central incisors being evaluated. In the discrimination test, the majority of dentists were able to identify reliably occlusal interference of ≥50 μm regardless of the palpation method used.

    Anodic characteristics of amorphous nickel-value metal alloys containing small amounts of platinum group elements in 0.5 M NaCl (1987)

    Notes: Abstract By utilizing the characteristics of amorphous alloys capable of possessing specific electrocatalytic activity and corrosion resistance by alloying and surface activation treatment, an attempt was made to find amorphous alloys which are active as the anode material for production of sodium hypochlorite by electrolysis of seawater. Amorphous Ni-Nb and Ni-Ta alloys containing only 0.5–2.0 at % palladium and other platinum group metals showed a very high activity for chlorine production by electrolysis of 0.5M NaCl at 30°C when they were previously immersed in 46% HF for surface activation. The current efficiency of these surface-activated alloys for chlorine evolution considerably exceeded that of the currently used, most active Pt-Ir/Ti electrode for electrolysis of seawater. The surface activation treatment resulted in preferential dissolution of alloy constituents unnecessary for the electrocatalytic activity, i.e. nickel and valve metals, with a consequent enrichment of electrocatalytically active platinum group elements in the surface-activated layer. The corrosion weight loss of the surface-activated amorphous alloys under the steady state conditions for chlorine production was undetectable by a microbalance.
