Abstract:
An image heating apparatus includes a heater which heats an image on a recording material, which extends in a direction perpendicular to a moving direction of the recording material; a first temperature detecting member for detecting the temperature of the heater; power controlling device for controlling the power supplied to the heater, so that the temperature detected by the temperature detecting member remains constant; a second temperature detecting member which is positioned at a location apart, in the longitudinal direction of the heater, from where the first temperature detecting member is positioned; and an interrupting device for interrupting the imaging heating process in accordance with the temperature detected by the second temperature detecting member.
Abstract:
A method of processing waste gas exhausted from chemical vapor deposition equipment, which entails:a) contacting a waste gas containing viscous substances with a filtering aid agent,b) passing the waste gas containing the viscous substances exhausted from the chemical vapor deposition equipment, and which has been contacted with the filtering aid agent, through a filtering and dust collecting unit, whereby the viscous substances are condensed with the filtering aid agent on the filtering and dust collecting unit, andc) removing the condensed matter from the surface of the filter, thereby preventing clogging thereof.
Abstract:
An image forming apparatus includes a movable image bearing member, having a photosensitive layer; an image forming device for forming an image on the image bearing member: a charging member for charging the image bearing member; and a light radiating device for radiating light on the image bearing member; a detector for detecting a datum rotating to a thickness of the photosensitive layer on the basis of the voltage-current characteristic between the charging member and image bearing member; and a controller for controlling the amount of light radiated from the light radiating device to be increased with decrease in the thickness of the photosensitive layer, in response to the detector.
Abstract:
An apparatus for non-invasively measuring the oxygen saturation in the blood of a subject comprises light sources for irradiating a sample of blood in tissue with at least a first light beam and a second light beam having different wavelengths. A switching device drives the light sources and sequentially switches the irradiation of the sample of blood between the first and second laser beams. A photoelectric detector detects light transmitted through or reflected from the sample of blood and provides an electrical output signal indicative of the intensity of the detected light. A converter converts the electrical output signal of the photoelectric detecting device to a power spectrum, and a processor processes the power spectrum and calculates the oxygen saturation of the sample of blood. The blood oxygen saturation in the blood can be measured with high accuracy based on the detection of the light intensity transmitted through or reflected from the blood, regardless of the presence or absence of a pulsed blood flow. Additionally, by irradiating the subject by switching between laser beams of two wavelengths, the subject receives less irradiation than when two lasers are used at the same time. Thus even if the amount of irradiation at each wavelength is slightly increased, the accuracy measurement can be improved without adversely affecting the subject.
Abstract:
The present invention provides an image forming apparatus with an image forming device for forming a developer image on a recording material, an applicator for applying developer to form an image on an image bearing member to form a developer bearing area. A length of the developer bearing area in the generatrix direction of the image bearing member is longer than a maximum image width on the image bearing member in the generatrix direction thereof.

Abstract:
A one-chip microcomputer including a central processing unit, a direct memory access controller and a random-access memory. In a DMA operation mode, data stored in the random-access memory is transmitted through common terminals to the exterior by means of a time-division control circuit or registers for parallel-serial conversion. The common terminals are also used for a CPU operation mode.
