Abstract: An improved disposable glucose test strip for use in a test meter of the type which receives a disposable test strip and a sample of blood from a patient and performs an electrochemical analysis is made using a non-conductive integrated reagent/blood separation layer containing a filler, an enzyme effective to oxidize glucose, e.g., glucose oxidase, and a mediator effective to transfer electrons from the enzyme. The integrated layer formulation is printed over a conductive carbon element to form a working electrode. The filler, for example a silica filler, is selected to have a balance of hydrophobicity and hydrophilicity such that one drying it forms a two-dimensional network on the surface of the conductive element. The response of this test strip is essentially temperature independent over relevant temperature ranges and is substantially insensitive to the hematocrit of the patient.

SOLUTION: This implement comprises a driving disk 4 for weed processing installed on the side position of tillage tines 1 on a tillage axis 2 to dissolve above-mentioned problem. A following disk 5 having corrugated outer periphery formed in a floral pattern is installed close to the driving disk 4 on the out side of the disk 4. The following disk 5 is rotatably mounted on a lower machine frame 6 of a transmission case 3.

Abstract: PROBLEM TO BE SOLVED: To transmit a voice and music or a synthetic voice and a robot operation signal to a robot by one transmission signal. SOLUTION: A robot control part 11 of a personal computer 1 generates text information S1, and generates the robot operation signal S2 from the text information S1. A synthetic voice generating part 12 generates a synthetic voice signal S3 from the text information S1 generated by the robot control part 11, and a motor control part 13 generates a motor control signal S4 from the robot operation signal S2. An AM modulator 14 generates an AM modulated wave S5 from the motor control signal S4, the AM modulated wave S5 and the synthetic voice signal S3 are synthesized by an adder 15, and are sent out to an audio line 3 as a synthetic sound electric signal S6 from a sound board 16.
