A position movement alarm system using GPS satellites and a cellular phone system is used to transmit automatically and directly a fact of movement of a movable goods from its original position, when the goods is moved opposing to the intension of an owner of the goods due to any reasons, from a position information monitor•alarm terminal (child device) 4 installed in the movable goods to owners cellular phone terminal( parent device) 2 having a GPS position information processing function through no third person organization such as an alarm center and a service center and the like.
摘要:
An order-reception system has: an order-reception subsystem which receives, from a customer, customer order information including order-reception information and/or support request information and customer information; a business management subsystem having a customer-information database storing the customer information including information regarding a price of a commodity purchased frequently by the customer, and a cost of a support requested frequently by the customer, the price and the cost set by a seller; an order-entry subsystem which performs an order-reception processing based on the customer order information; and a delivery subsystem which arranges delivery of the commodity and providing of the support.
摘要:
A water treatment control system for minimizing trihalomethane formation includes chlorine injection equipment having a plurality of chlorine injectors (11d, 12, 13), a fluorescence analyzer 7 provided on the upstream of the chlorine injectors, and a water flowmeter 6. An chlorine injection rate necessary to reduce a trihalomethane formation potential is calculated by a chlorine injection rate calculating apparatus 14a based on a measured value from the fluorescence analyzer 7. An chlorine injection amount from the chlorine injectors is controlled by chlorine injection amount control apparatuses 15a–15c based on the chlorine injection rate and a measured value from the flowing water flowmeter 6.

摘要:
A probe for measuring oxygen concentration including an immobilized polypyridine metal complex, which can be used for measurement of oxygen concentration even in a case where the exciting ray to be used and luminescence are visible rays and which can stably be used even when it is directly immersed in a liquid to be examined without a protective membrane, which makes miniaturization of a probe possible.
摘要:
A thickness standard sample consisting of a base plate and an even thick foil fixed on the base plate. The foil has a uniform standard thickness for calibrating an X-ray fluorescence thickness gauge or the like. The sample is very inexpensive and serves as an excellent uniform thickness standard sample so that an operator may set any point on the sample surface to the calibrating gauge axis.
摘要:
Provided is a photophysicochemical cell including a liquid phase medium of a fuel such as a redox liquid, etc., a photoanode electrode formed of a porous electrically conductive material or an n-type visible-region semiconductor having a high carrier density, the photoanode electrode or the n-type visible-region semiconductor being inserted in the liquid phase medium and an electrode formed of an electrically conductive material capable of reducing oxygen, the electrode being inserted in the liquid phase medium as a counter electrode, in which oxygen is caused to be co-present in the above liquid phase medium, light is applied to the above photoanode electrode thereby to oxidatively photolyze the above fuel on said anode electrode without applying any auxiliary external voltage and oxygen is thereby reduced on the above counter electrode thereby to generate a photoelectric current in said external circuit, according to which photophysicochemical cell, a wide range of compounds that naturally include alcohols such as methanol and also include urea, ammonia, agarose, glucose, amino acid and, further, biomass such as cellulose can be decomposed as a fuel to generate photocurrent.
