摘要： PURPOSE:To achieve higher sensitivity and selectivity in an electrode wherein a plural ity of numerous fine pore electrodes are arranged by modifying upper electrodes with a high polymer film, a low polymer film, an enzyme film or the like to promote an electrode reaction of an interfering substance or to cause a chemical reaction of the interfering substance in a catalytic manner among the electrodes located at upper, middle and bottom parts. CONSTITUTION:At least more than one working electrodes are arrayed being separated from one another at very small intervals and reaction with an interfering substance is suppressed by increasing a current amplification factor by a redox cycle between the electrodes or shortening a period during which a desired material diffuses between the electrodes. Moreover, some electrodes are modified using a substance which acts as a catalysis for electrochemical reaction of the interfering substance to promote a reaction while an area of the electrodes is made larger so as to check a harmful substance from diffusing near an electrode for detecting the desired material. Low and high polymer thin films and an enzyme thin film modifying the upper electrodes herein used are polyvinyl ferrocene, polyvinyl pyridine. An insulating substrate is used for a substrate and metal and an organic oxidizing/reducing high polymer thin film for a reference electrode.

摘要： PURPOSE:To extremely diminish the inter-electrode spacing of two working electrodes to sub-micron order by determining the inter-electrode spacing by the thickness of insulating films. CONSTITUTION:A photoresist is applied on a silicon substrate 1 to 1mum thickness. The silicon substrate 2 is then put into an oven and is baked. Thereafter the substrate is subjected to contact exposing by using a chromium mask. This substrate 2 is developed in a resist developing soln. and is subjected to washing and drying, by which mask patterns are transferred onto the resist. Chromium and platinum are then successively deposited by sputtering thereon. The substrate 2 is immersed into methyl ethyl ketone and is subjected to an ultrasonic treatment by which the resist exclusive of the electrode forming parts is peeled and the lower working electrode 3 is formed. Silicon dioxide is thereafter deposited by sputtering to form the 1st insulating film 4. The resist is again peeled in the methyl ethyl ketone to form the upper working electrodes 5, 6. The surface of the substrate 2 is coated and the 2nd insulating film 6 is formed. The insulating films 8, 4 are etched to expose the electrode 3.

摘要： PURPOSE:To realize an access to a file from another information processor in parallel with the key input processing by deciding the presence or absence of the reception data on a transmission/reception buffer and transferring the data stored in the file of its own information processor in response to said reception data. CONSTITUTION:A basic input/output routine which gives an access to a file is not started in a basic input/output routine which reads the key data stored in a key input buffer 61. A file received an access before said basic input/output routine is carried out is kept closed. Thus the presence or absence of the reception data of a transmission/reception buffer is decided in the basic input/output routine. Based on the reception data, the data stored in the file of its own information processor is outputted to the transmission/reception buffer or the data received by the transmission/reception buffer is transferred to a prescribed file.
