    摘要： This invention is for improving the radiation hardness or radiation resistance of GaAs MESFETs. According to this invention, an n-type active layer is formed by doping in the GaAs crystal. The n-type active layer includes an upper layer and a heavy doped lower layer. A Schottky gate electrode is provided on the active layer so that the carrier concentration in the active layer and the thickness of the active layer are set to required values. According to this invention, not only in the case of a total dose of exposure radiation of R=1.times.10.sup.9 roentgens but also in the case of a higher total dose, at least one of the threshold voltage V.sub.th of the GaAs MESFET, the saturated drain current I.sub.dss there of, or the transconductance g.sub.m will remain in their tolerable ranges. Consequently a semiconductor device comprising the GaAs MESFET and a signal processing circuit cooperatively combined therewith can operate normally as initially designed, with the result of conspicuously improved radiation hardness.

    摘要： This invention is for improving the radiation hardness or radiation resistance of GaAs MESFETs. According to this invention, an n-type active layer is formed by doping GaAs crystal evenly in the depth direction of the GaAs crystal, and a Schottky gate electrode is provided on the active layer, so that the carrier concentration in the active layer and the thickness of the active layer are set to required values. According to this invention, not only in the case of a total dose of exposure radiation of R=1.times.10.sup.9 roentgens but also in the case of a higher total dose, at least one of the threshold voltage V.sub.th of the GaAs MESFET, the saturated drain current I.sub.dss thereof, and the transconductance g.sub.m will remain in their tolerable ranges.

    摘要： A breath-synchronized concentrated-oxygen supplier comprising an oxygen concentrator for producing and storing oxygen-enriched gas, and a buffer tank having an inlet connected to the oxygen concentrator and an outlet for temporarily storing the oxygen-enriched gas obtained from the concentrator. A valve is mounted in the outlet of the buffer tank so as to control flow of the oxygen-enriched gas from the buffer tank to the respiratory system of a living body, the valve having a gas flow path that is open to the atmosphere. A sensor, provided for sensing the respiration of the living body, generates an output signal indicative of the inhalation and exhalation phases of the respiration. An input device, on which a ratio between the entire length of the inhalation phase and a specific end portion thereof is set is included as is a regulator responsive to the sensor and input device for detecting the duration of each inhalation phase in succession based on the output signal from the sensor. The regulator also opens the valve at the beginning of each inhalation phase, and maintains the open time of the valve based on a period determined by a combination of averaging the preceding inhalation durations and the ratio set on the input device. Oxygen-enriched gas is supplied to the living body during each inhalation phase except for the specific end portion thereof, and the buffer tank acts to make the initial flow rate of the oxygen-enriched gas higher than the steady flow rate thereof in each inhalation phase.

    摘要： An ifax communication unit that performs communication of image data through the Internet, which is mounted on an image forming apparatus, includes a destination address table, which is stored in a memory unit, for setting original scanning resolution to resolution defined by a protocol of the Internet. While setting of the scanning resolution is valid, when a user selects transmission of image data by an ifax transmission (E-MAIL) mode, even if the original scanning resolution is set to another resolution in a FAX mode, the resolution is changed to the resolution defined by the protocol and original scanning and transmission is performed.

    摘要： Method and apparatus for analyzing the propagation of arterial pulse waves in a patient's circulatory system. The apparatus comprises R-wave detecting means for outputting an R-wave timing signal at the time of detection of the R-wave component contained in a detected electrocardiographic signal. A pulse wave peak detecting means is provided for outputting a peak timing signal at the time of the detection of a selected peak of the arterial pulse wave detected in the peripheral blood vessels of a patient's circulatory system. A pulse wave propagation time counter is provided for successively counting the time interval from the input of the R-wave timing signal to the input of the peak timing signal, and a pulse wave propagation time analyzer is provided for analyzing the distribution of pulse wave propagation times and other detected biophysiological parameters, from which an effective diagnosis of the condition of the patient's circulatory system can be made.
