Abstract: An imaging device for dental treatment for use in an instrument for dental treatment with a head to which a rotary cutting tool can be attached. The imaging device for dental treatment comprises: an imaging module with an imaging element; and a mounting section through which the imaging module is detachably attached to the instrument for dental treatment such that the imaging module is on the bottom side or on the lateral side of the head, and that the imaging module is in a posture that causes the imaging axis of the imaging module and the rotary axis of the rotary cutting tool to be substantially parallel.

Abstract: A diagnostic/treatment instrument such as a handpiece equipped with a dental treatment tool, etc. is provided with a light radiating unit that can distinctively detect a dental lesion, to facilitate the treatment of the lesion. A light source for emitting light that can distinctively detect the lesion is mounted near the head of the handpiece to which a diagnostic/treatment tool can be attached. The light emitted from the light source illuminates an area forward of the diagnostic/treatment tool. Alternatively, the light source comprises a plurality of light-emitting devices which are arranged around the periphery of the forward end of the handpiece head in such a manner as to encircle the diagnostic/treatment tool, and radiates light to illuminate the area forward of the diagnostic/treatment tool.

Abstract: An object of the preset invention is to provide a medical lighting apparatus capable of illuminating an affected part with proper illuminance while assuring a work space for an operator near the affected part. A medical lighting apparatus for irradiating an affected part with light includes: a light source (a light emitting element); a light condenser (a collimate lens and a condenser lens) for condensing light emitted from the light source; an image forming unit (an image lens) for forming an image on the affected part from the light condensed by the light condenser; and an aperture portion provided between the light condenser and the image forming unit and regulating passage of the light condensed by the light condenser.

Abstract: A sense amplifier section comprises two stages of latch-type sense amplifier circuits, i.e., a primary-stage latch-type sense amplifier and a secondary-stage latch-type sense amplifier, wherein stress exerted on the primary-stage latch-type sense amplifier is reduced significantly to ensure high accuracy in amplification. In the above configuration including the secondary-stage latch-type sense amplifier, when an amplified output from the primary-stage latch-type sense amplifier reaches a predetermined voltage level (e.g., 50 mV), a transition to amplifying operation of the secondary-stage latch-type sense amplifier is enabled so that a time duration of operation of the primary-stage latch-type sense amplifier (corresponding to a time duration of stress exertion on the primary-stage latch-type sense amplifier) can be shortened significantly.

Abstract: A medical living body observation apparatus, an intraoral photography system and a medical treatment appliance which can be used conveniently by a general user at home as well as a technician, e.g. a dentist or a physician. There is provided an irradiation means (2) comprising an exciting light emission section (2a) emitting an exciting light for causing a lesion to radiate fluorescence, and an illumination light emission section (2b) emitting a light for illuminating the periphery of the lesion. The irradiating means (2) can simultaneously irradiate the illumination light and the exciting light.

Abstract: A dental injecting apparatus for injecting a dental filler and a dental tool attached to such a dental injecting apparatus. The apparatus includes: an injection rod for injecting a dental filler; an injection rod driver for performing a dental filler injecting operation that causes the injection rod to move in a dental filler injecting direction by using the force of a power source; and a controller for controlling the dental filler injecting operation of the injection rod driver.

Abstract: A small-sized and high-powered medical illuminating device, and other devices, such as a medical photopolymerizer and a medical hand-piece, including the medical illuminating device. The medical illuminating device includes plural light emitting components which are integrated with a base forming into a light emission module. The base includes a substrate member having at least a concave, and the light emitting component is mounted on a bottom surface of the concave. Side surfaces of the concave of the substrate member function as a reflector for reflecting the light emitted from the light emitting component towards its front.

Abstract: A catalyst member for a lighter comprises a linear base material, and a fusion bonding material, which is constituted of a material selected from the group consisting of a powdered metal and a vitreous fused material. A finely divided catalyst carrier, which is constituted of a metal oxide, is secured to the surface of the linear base material by the fusion bonding material. A catalyst is deposited on the surface of the finely divided catalyst carrier.

Abstract: A combustion device in a lighter, such as a gas lighter, comprises a base portion, which is associated with a nozzle for jetting a fuel gas and is provided with a primary air hole for introducing primary air into the fuel gas having been jetted from the nozzle, and a combustion cylinder, in which the fuel gas containing the primary air mixed in is burned. The combustion cylinder has a multiple pipe structure comprising a combustion inner pipe, in which the fuel gas containing the primary air mixed in flows, and a combustion outer pipe, which is located around the outer periphery of the combustion inner pipe and at a predetermined spacing from the combustion inner pipe. The space, which is defined between the combustion inner pipe and the combustion outer pipe, is formed as a secondary air flow path, through which secondary air is supplied to a combustion flame.

Abstract: A portable heater is made up of a cylindrical outer case 2 with at least one end thereof opened; a container to be heated 6 fixedly housed in the outer case 2 with a gap between the container and said outer case for the updraft of a combustion gas, the container being made of a cylindrical heat resisting container body 6c having a top 6b provided with an opening tab 6a; a burner 3 which is equipped with an ignition means 8, and is fixedly housed in the outer case 2 at a lower inside thereof so as to heat the container 6; and a fuel tank 4 fixed in a lower inside of the outer case 2 for supplying fuel to the burner 3. The container 6 holds contents to be heated when the heater is in use, and the outer case 2 has vent holes for supplying air from the outside to the burner 3. Thereby, contents of the container can be heated at any desired time and place without drawing the contents of the container by opening the top of the container.
