Abstract: In a positioning system, an arithmetic processor analyzes positioning data acquired by a receiving terminal and determines a positioning target location. Upon reception of positioning data, the arithmetic processor accumulates the positioning data on analysis data stored in a storage section prior to the reception, stores an accumulated data as new analysis data, and transmits an analysis result to the receiving terminal. The receiving terminal transmits positioning data, acquired for a predetermined time, to the arithmetic processor and continues to acquire positioning data. Upon reception of the analysis result, the receiving terminal determines whether the analysis result is good or poor. When the analysis result is poor and the positioning data is stored for the predetermined time from a last transmission of the positioning data, the receiving terminal transmits the positioning data to the arithmetic processor and continues to acquire positioning data.

Abstract: A laser scanner measuring system is disclosed, which has a laser scanner and a calibration target. The laser scanner comprises a light emitting element for emitting a pulsed laser beam, a rotary projecting unit for projecting the pulsed laser beam, a distance measuring unit, and a control unit for driving and controlling the light emitting element and the distance measuring unit. The calibration target has a reflection sector with a known shape and with high reflectance and is installed at a known position. In use, there is a step for judging a reflected pulsed laser beam from the reflection sector by detecting a level of light quantity, a step for determining a center position of the reflection sector based on the result of the judgment, and a step for calibrating the laser scanner measuring system based on the determined center position and on the known position.

Abstract: A dissolving apparatus has a cylindrical tubular container closed at both ends with its center axis being inclined to the horizon. A center of an interface between a gas and a liquid in the container is positioned at a center in a lengthwise direction of a side wall of the container. Two inner spaces of the container above and below the interface are referred to as a gas section and a liquid section. An injection inlet for injecting a gas-liquid mixed fluid into the container is provided at a level corresponding to, or lower than, the interface. A liquid outlet for discharging the liquid is provided near a bottom of the liquid section of the container. Since the container is inclined, the interface can have an area large enough to promote dissolution of the gas into the liquid. Since the depth of the liquid in the liquid section is sufficiently deep, the liquid can be prevented from being discharged through the liquid outlet with large gas bubbles being present therein.

Abstract: Flush toilet equipment comprises a bowl, a flush mechanism that supplies flush water to the bowl through a flush water passage, and a minute bubble generator. The minute bubble generator generates minute bubbles. The bubbles are 0.1-1000 ?m in bubble diameter and mixed with the flush water. In this construction, since the minute bubbles are fully diffused into the flush water, various effects such as improvement of toilet flush effect, etc. can be further enhanced.
