Abstract: In a shoe fit evaluation system, a dimensional difference calculator calculates a part dimensional difference, which is a difference between a measurement value of a foot part dimension and a last part dimension corresponding to the foot part, by performing a certain adjustment for the part. An evaluation processor calculates a last matching rate based on the part dimensional difference. An outputter outputs information regarding the last matching rate. The dimensional difference calculator calculates the part dimensional difference by performing, as the certain adjustment, subtraction of an allowance for specific stretch properties of each shoe part.

Abstract: A compact and easily transportable temporary flush toilet can be installed where the toilet cannot be connected to a water supply system and no frequent maintenance is possible. The temporary toilet includes a toilet bowl, a flush water tank for storing flush water used to flush the toilet bowl, a sewage tank for storing sewage from the toilet bowl, a water vapor separator for separating water from gas containing water vapor vaporized from sewage in the sewage tank, an exhaust pipe through which gas is guided from the top of the sewage tank to the water vapor separator, and a distilled water pipe through which water separated from the gas in the water vapor separator is supplied to the flush water tank. Thus, storage of the sewage, microbial decomposition of waste, and evaporation of the sewage take place in the sewage tank alone.

Abstract: A organic substance treatment device is proposed which includes a cylindrical treatment tank (11) having a central raised portion on its bottom surface to create a step. An agitating vane unit (14) is provided on the raised portion. The vane unit is rotated counterclockwise if the device is located in the northern hemisphere of the earth to form a counterclockwise vortex in the liquid in the tank. By supplying air into the vortex, air is efficiently taken into the liquid. This increases efficiency with which organic substances is decomposed by aerobic microorganisms.

Abstract: Disclosed is an object search apparatus, including: an imaging unit to acquire image data of a point group; a radiation unit to scan the imaging area; a three-dimensional analysis unit to calculate three-dimensional data indicating position coordinates of the point group, from the image data; a master data storage unit to store a master data which is each of the three-dimensional data of a search object to be searched in the imaging area in a plurality of directions; and a judgment unit to position one point of the master data in each direction to each point of the three-dimensional data, to judge whether position coordinates of points of the positioned master data in any direction approach to position coordinates of corresponding points of the three-dimensional data of the imaging area, and to perform a search of the search object based on a result of the judgment.
