A method for determining the concentration of a substrate in a sample solution using an electrode system comprising a working electrode and a counter electrode, both being formed on an electrically insulating base plate, and a reaction layer which contains at least an oxidoreductase and an electron mediator and is formed on the electrode system to electrochemically measure a reduced amount of the electron mediator resulting from enzyme reaction in the reaction layer, wherein a third electrode is formed as an interfering substance detecting electrode somewhere apart from the reaction layer to detect supply of the sample solution on the basis of an electrical change between the counter electrode and the third electrode. A current flowing between the counter electrode and the third electrode is measured which is taken as a positive error. Subsequently, voltage application between the counter electrode and the third electrode is released and a voltage for oxidizing the reduced form electron mediator is applied between the working electrode and the counter electrode to measure a current flowing between the two electrodes. Influences of any interfering substance such as easy-to-oxidize substance are reduced, whereby a highly reliable value of substrate determination can be obtained.

The invention relates to a manual gas valve for use with either LP gas or natural gas operation with the purpose of solving the technical dilemma that the existing gas valve cannot be converted conveniently for use with different gases having different heating values. The manual gas valve of the present invention comprises a nozzle 1, a 8×1.9 O-shaped ring 2, a nozzle holder 3, a valve body 4, a faucet 5, a regulating lever 6, a 1.78×1.78 O-shaped ring 7, a spring 8, a stop plate 9, a pair of bolts 10, a mounting cover 11, and a valve stem 12. By utilizing the manual gas valve of the present invention, LP gas and natural gas can be used interchangeably and the gas flow can be conveniently regulated to achieve a similar heating value with either LP gas or natural gas operation. In addition, the conversion is easy and convenient, without requiring the use of any special tools or relying on any additional testing apparatus. No special skill or training is needed so that it is particularly suitable for self regulating operation by customers. Moreover, the manual gas valve is safe and reliable.

An agricultural working machine has at least one working unit, a driver's cab; at least one display unit provided in the driver's cab and having a basic electronic viewing screen for showing a plurality of machine and / or crop parameters stored in different functionality windows, the at least one display unit being assigned to the at least one working unit, the at least one display unit with the basic electronic viewing screen and the different functionality windows being formed so that when at least one additional functionality window is open, an open functionality window is zoomed.

A device for preparing a fluid food at a desired consumption temperature on demand, and for preparing foods or food supplements from components selected based on personal preferences and / or nutritional needs of individual users. The device comprises two reservoirs (12, 14) of water, a container (18, 20) containing a food formula, a data processor (23) and a controller (24) for dispensing a selected quantity of water from each of the reservoirs and a selected quantity of food formula from the formula container into a mixing container (26). The invention is useful in preparing food for infants and in preparing food according to individualized nutritional requirements of individuals of all ages, and in personalized drink preparation.

An image recording apparatus including: a sheet-supply cassette which accommodates a stack of recording sheets and which is insertable into and removable from a main body of the apparatus; an end wall which is disposed at a downstream end of the cassette in a sheet-supply direction in which the sheets are supplied, so as to extend in a direction perpendicular to the sheet-supply direction and which has a height larger than that of a maximum number of the sheets that can be accommodated in the cassette; an image recording unit disposed in the main body for recording an image on the sheets; an arm disposed in the main body and pivotable about a shaft which extends in the direction perpendicular to the sheet-supply direction; a sheet-feed roller which is disposed at a free end of the arm and which is, in a state in which the cassette is inserted into the main body, in contact with an uppermost one of the sheets accommodated in the cassette and which feeds the uppermost one of the sheets toward the image recording unit; and a link mechanism which is disposed in the main body for raising and lowering the roller and the arm and which cooperates with the end wall to retract the roller and the arm above the cassette when the cassette is inserted into and removed from the main body.

The present invention is characterized by arranging a flow path 200 for supplying driving gas to a tool mounting portion 170 from a robot base 110 to the tool mounting portion 170 through the interiors of a rotation frame 120, a tube 220, a shoulder 140, a swing arm 150 and a tool mounting rotation arm 160.

The present invention relates to optical communication equipment and a vehicle control method, and in particular, the present invention is applied to a system utilizing inter-vehicle communication equipment via optical communication to notify information of traffic regulation utilizing optical communication according to an inter-vehicle communication system so that traveling of a vehicle can be controlled easily and reliably even in such a complicated place where a plurality of roads intersect as in urban cities or the like.

The invention provides a power supply device capable of making the temperatures of the battery cells almost consistency at any position by reducing the temperature differences, and a vehicle having the same.A power supply device includes rectangular battery cells 1, resin separators 2, end spacers, thick metal end plates, and coupling members. The separator 2 is inserted between the cells 1 to insulate adjacent cells 1 from each other, and in thermal contact with the cells 1. The end spacers cover end battery cells on the opposed end surfaces of a battery block composed of the cells and the separators alternately arranged. The end plates cover the surfaces of the end spacers. The coupling members couple the end plates to each other. The separators form gaps for flowing air along the surfaces of the cells in contact with the separators. The end spacers have hollow layers on their surfaces in contact with the cells, and define closed chambers.
