Title: Electrode
Inventor: NAKAMURA KENICHI
IPC: G01N27/40
Filed: 1978-04-21
Abstract: PURPOSE: To measure the substrate concentrations ob enzyme or activity of enzyme rapidly and readily by forming the enzyme electrode through directly and chemically bonding (particularly covalent bonding) coenzyme to current collectors and fixing the same and using this.  
     CONSTITUTION: Nicotineamide Adenine Dinucleotide (NAD, coenzyme) is reacted with, e.g., succinic acid anhydride to introduce carboxylic groups. On the other hand, SnO 2  NESA glass (current collector) is subjected to hydrophilic treatment to form hydroxyl groups on the SnO 2  surface, after which the above-mentioned  denatured NAD is reacted to fix the NAD on the NESA glass through ester bond. After the NAD fixed electrode is formed by directly chemically bonding 4 the coenzyme 2 to the current collector 3 in the above-mentioned manner, it is dipped in a solution containing enzyme (e.g., lactic acid dehydrogenase) 1 to prepare the  NAD- enzyme bond, which is then treated with crosslinking reagent (glutaraldehyde, etc.) to fix the enzyme. The substrate (lactic acid) concentration is measured  by using this. If this is used in the state where enzyme is not bound, the measurement of enzyme activity is possible.

Title: Magnetic disk device
Inventor: UEMATSU YUKIHIRO
IPC: G11B33/14
Filed: 1982-03-26
Abstract: PURPOSE:To prevent a trouble due to the entry of dust, by providing a pressure sensor for detecting the pressure in a sealed chamber, and detecting deterioration in the airtightness of a cover. CONSTITUTION:When magnetic seals 5A and 5B are deteriorated, outside air is injected into the inside of the cover 4 as shown by an arrow E. In this case, the pressure at a part B becomes higher than normal, and the pressure at a part C increases. When a magnetic seal 5C is deteriorated, the inside air flows out as shown by an arrow E. In this case, the pressure at the part C does not reach normal pressure. The internal pressure of the cover 4 is detected by the output of a piezoelectric element 10. Therefore, while a recording medium 3 is driven to rotate, whether the C part pressure is within a specific pressure range or not is monitored to detect the aritightness of the cover 4, i.e. the deterioration of the magnetic seals 5A, 5B, and 5C, etc. When the pressure is not within the specific range, a comparator 11 outputs a signal S.
