IPC: G01N27/327
Filed: 1989-11-30
Abstract: PURPOSE:To manufacture the title sensor having a stable characteristic by simple method wherein an electrode is formed in such a state that the enzyme of a built-in enzyme modified electrode is uniformly mixed with other electrode component. CONSTITUTION:An enzyme modified electrode is prepared by molding a composition obtained by uniformly kneading enzyme and an electrode component other than enzyme with a vehicle such as liquid paraffin or coating the surface of an electrode base material with said composition. This electrode is incorporated in a sample chamber while the sample chamber is filled with an electrolyte by a pump and a proper reference electrode is used as a counter electrode to apply a current to the electrodes. Subsequently, a proper amount of a sample containing a substance to be measured is injected in the sample chamber from a sample injection port. The oxidizing current generated by the reaction of the substance to be measured in the sample with the enzyme in the electrode is converted to a voltage value to be recorded on a recorder or the voltage value is subjected to A/D conversion and taken in a computer to measure the substance to be measured. The measured value is compared with that of a control solution whose concn. is preliminarily cleared to calculate the concn. of the substance to be measured in the sample.

Title: Inverter equipment
Inventor: YAMANAKA YUKIO
IPC: H05B41/24
Filed: 1991-11-25
Abstract: PURPOSE:To reduce a ripple current of a smoothing capacitor by operating a chopper in synchronization with an inverter and cancelling a charging current from the chopper and a discharge current to the inverter each other in the capacitor between the chopper and the inverter. CONSTITUTION:When a transistor Q2 is varied from ON to OFF, a voltage between a collector and an emitter of a transistor Q3 is lowered, a terminal Q of a monostable multivibrator M1 becomes a high level, while a terminal Q' thereof becomes a low level. Thus, a transistor Q1 is turned OFF, and energy of an inductor L1 is discharged to a smoothing capacitor C1 through a diode D1. On the other hand, when the transistor Q3 is turned ON at an inverter side, a discharge current flows from the capacitor C1 through the transistor Q3. Accordingly, a current obtained by subtracting a collector current of the transistor Q3 from the current flowing to the diode D1 becomes a ripple current of the capacitor C1.

Filed: 1989-11-29
Abstract: PURPOSE:To prevent a spikelike voltage by connecting a reverse conduction diode in parallel with a switch unit and turning OFF one unit slightly in delay by a controller. CONSTITUTION:Diodes 32a-32d which reversely conduct are connected in parallel with switch units 31a-31d.
