Abstract: A microwave heating apparatus (101) includes a burning chamber (103) in which an object (102) to be burned is placed, a magnetron (116) for applying microwaves into the heating apparatus, a cooling gas introducing mechanism (112b) for introducing a cooling gas from outside the heating apparatus into the heating apparatus, a cooling gas channel (113b) through which the cooling gas flows to the burning chamber (103), heat-generating members (114a to 114e) for self-heating with microwaves applied thereto to heat the cooling gas flowing through the cooling gas channel (113b) and a control section (117) for, when the burning chamber (103) having the object (102) to be burned placed therein is cooled, causing the cooling gas introducing mechanism (112b) to introduce the cooling gas into the heating apparatus, and causing the magnetron (116) to intermittently apply microwaves into the heating apparatus.

Abstract: An intra-oral measurement device according to the present invention is provided with a light projecting unit for irradiating lights in at least two different wavelengths along an identical light axis toward an object to be measured that includes at least a tooth in an oral cavity, and an image pickup unit for receiving lights reflected on the object to be measured and picking up an image, so that an intra-oral shape can be accurately measured without spraying the metal powder within the oral cavity.

Abstract: The present invention aims to provide an intra-oral measurement device and an intra-oral measurement system capable of measuring an inside of an oral cavity at high accuracy without increasing a size of the device, and includes a light projecting unit for irradiating a measuring object including at least a tooth within an oral cavity with light, a lens system unit for collecting light reflected by the measuring object, a focal position varying mechanism for changing a focal position of the light collected by the lens system unit, and an imaging unit for imaging light passed through the lens system unit.

Abstract: To provide an installation structure and an installation method of a communication equipment to reduce a number of components of the equipment and make the installation work easy. A communication equipment and an installation structure of the communication equipment to be installed, e.g., outdoors is provided. A handle for carrying the communication equipment also serves as a fixation component of the communication equipment. A method for installation of a communication equipment comprises providing an inclined portion formed at a part of bottom surface of a communication equipment and keeping the communication equipment in a forward-inclined position temporarily with the assistance of the inclined shape portion when the communication equipment is set on a fixation mount to fix the communication equipment preparatory to installation.

Abstract: It is an object of the present invention to enable a strict and efficient inspection for a defect in a geometric pattern of a ferromagnetic thin-film layer of a master disk for magnetic recording media used in a device such as an AVHDD, in which initial information is recorded. Alignment marks 16 are formed in a plurality of positions on a circumference concentric with the recording section simultaneously with forming recording bands 14 constituting the information recording section on the master disk 10, the image of the recording bands 14 and the marks 16 on the master disk 10 is obtained, the image of recording section and non-defective product information is aligned based on the image of the marks 16, and then the images of the recording bands 14 are compared with the non-defective information to inspect the geometry pattern of the information recording section.

Abstract: A light having a single wavelength which is emitted from a light emitting element comprising a light emitting diode, a semiconductor laser or the like is changed to a parallel light by a collimator lens. The parallel light emitted from the collimator lens which has been changed or is being changed to such a beam as to keep a small beam diameter for a long distance by a conical lens is irradiated on a surface of an object to be measured. The light diffused from the surface of the object to be measured is collected into a position detecting element by a condenser lens so that a distance on the surface of the object to be measured can be measured.

Abstract: A method for processing three-dimensional shape data includes steps of obtaining a plurality of point data along a surface of an object having a three-dimensional shape; taking out a point data from the obtained point data to be processed, approximating each specified number of point data in the to-be-processed point data adjacent the taken-out point data by a polynomial and then finding two unit vectors at the taken-out point data; finding an opening angle defined between the two found unit vectors; comparing the found opening angle with a predetermined threshold value of the opening angle, determining whether or not the found opening angle is not larger than the threshold value, and thinning the taken-out point data when the found opening angle is larger than the threshold value and not storing the taken-out point data in a storage unit, and leaving the taken-out point data without the thinning when the found opening angle is not larger than the threshold value and storing the taken-out point data in the st
