Abstract: 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.

Abstract: In preparation for facsimile transmission, a destination list is displayed. The destination list shows destination-name columns, Fax buttons, and E-mail buttons.

Abstract: Amorphous carbon coated tools include substrates formed from a cubic boron nitride sintered body, a diamond sintered body, a silicon nitride sintered body, or an aluminum oxide-titanium carbide sintered body, and amorphous carbon films thereon to make the cutting edges of the tools. The amorphous carbon films contain hydrogen at 5 atomic percent or below and have a maximum thickness of 0.05 ?m to 0.5 ?m on the cutting edges. The amorphous carbon films are most suitable for applications to cutting tools exemplified by cutters, knives, and slitters, and to indexable inserts used for example in turning tools including drills, endmills, and reamers, and milling cutters.

Abstract: An amorphous carbon coated tool includes a base material of WC base cemented carbide, and an amorphous carbon film formed on this base material. The cobalt content in the base material is at least 12% by mass. The maximum thickness of the amorphous carbon film is at least 0.05 ?m and not more than 0.5 ?m at the cutting edge. The amorphous carbon film is deposited with graphite as the source material by physical vapor deposition in an atmosphere substantially absent of hydrogen. The amorphous carbon film coated tool superior in wear resistance and adhesion resistance is preferably applicable to rotating tools such as drills, end mills and reamers, indexable inserts used for milling cutters and turning tools, and cutting-off tools such as cutters, knives, or slitters.

Abstract: An image forming apparatus supporting system includes a first control unit to perform a series of controls relative to the main body that performs the image forming operation; a program storage memory connected to the first control unit via an address bus and a data bus; a non-volatile memory to store maintenance data relative to the main body and an interface circuit that enables the interface between the non-volatile memory and an external device. Further, this system includes a second control unit that controls the main body so that maintenance data can be transmitted from a non-volatile memory to the external device via the interface circuit according to input/output items designated by the external device when the first control unit is not performing the control of the image forming operation in the main body.

Abstract: 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. 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.

Abstract: 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.
