Title: Determination of freshness of food, and electrode
Inventor: NAKAMURA KENICHI
IPC: C12Q1/32
Filed: 1980-02-08
Abstract: PURPOSE: To determine the freshness of foods, especially that of fish meat, easily and rapidly, by reacting a food extract liquid with an enzyme having selectivity to inosinic acid, inosine, and hypoxanthine, and detecting the concentration changes of the compounds caused by the enzymatic reaction.  
     CONSTITUTION: A liquid specimen obtained by the extraction of a food is treated with an enzyme which reacts specifically with each of inosinic acid (IMP), inosine (HxR) and hypoxanthine (Hx), and the change of the concentration of each component caused by the enzymatic reaction is determined by an electrochemical means. The freshness of the food can be obtained as the L-value or the M-value given by the formulas. Examples of the enzyme are : IMP dehydrogenase for IMP, N-ribosylpurine ribohydrolase for HxR, and xanthine oxidase for Hx. The electrode for the electrochemical determination is, e.g. a thin-layer electrode composed of immobilized inosinase and xanthine oxidase, and the one composed of immobilized 5'-nucleotidase, inosinase and xanthine oxidase.

Title: Image forming device and process cartridge
Inventor: TAKAMI NORIO
IPC: G03G15/08
Filed: 1997-01-29
Abstract: PROBLEM TO BE SOLVED: To prevent defective electrification from occurring because toner left after transfer is moved to an electrifying roller in an image forming device constituted so that the toner left after the transfer is recovered by a developing device. SOLUTION: Since the toner left on the surface of a photoreceptor drum 1 after a toner image is transferred is electrified to positive polarity, it is necessary that the toner left after the transfer is electrified to negative polarity in order to be moved to a developing roller 2 by back contrast between the drum 1 and the roller 2. When a positive-polarity electrifying bias is impressed on the electrifying roller 8 at an electrifying time, one part of the positive- polarity toner left after the transfer is moved to the surface of the roller 8.  Then, the toner left after the transfer and attached to the surface of the roller 8 is triboelecrtrified to the negative polarity by making the circumferential velocity of the surface of the drum 1 and the circumferential velocity of the surface of the drum 8 different and returned to the surface of the drum 1 from the surface of the roller 8. Then, the toner left after the transfer and electrified to the negative polarity is recovered by the roller 2.

Title: Water heater
Inventor: ISHII HIROO
IPC: F23N1/02
Filed: 1981-02-06
Abstract: PURPOSE:To improve the thermal efficiency and gas-flow controlling performance of a water heater, by employing such an arrangement that the fan speed and the opening of a main gas flow controlling valve are controlled by the function of an oscillator and by controlling the motor speed on the basis of an output signal produced from a controller in response to the temperature of hot water supplied. CONSTITUTION:The temperature detected by a temperature detector 8 is applied to a controlling means 9 and compared with a set value, and an output signal of the means 9 is in turn furnished to a flow control valve 7 for controlling the gas flow in a main gas passage 4 by changing the speed of a motor (not shown) and thereby keeping the temperature of hot water supplied at a set value. Further, since the motor is interconnected to a fan 18, the speed of the fan 18 is increased or decreased with change of the motor speed, so that air-flow rate is changed with gas-flow rate. Since, with such an arrangement, gas-flow rate can be controlled finely in response to the small change of temperature of hot water supplied, gas-flow rate controlling performance of the water heater can be improved. Further, since the air-flow rate can be controlled to meet with the combustion rate, the thermal efficiency of the water heater can be also raised.

Title: Main steam system radioactive nitrogen measurement device and its measuring method
Inventor: IBE HIDEFUMI
IPC: G01T1/167
Filed: 1989-01-27
Abstract: PURPOSE:To control the exact assessment of the concentration and the chemical form of radioactive nitrogen by grab-sampling a constant quantity of steam to measure after the steam is condensed in inactive gas at one to several atmospheres at the position as near as it can reach a pressure vessel of a main steam tube. CONSTITUTION:At first, a conventional sampling system is operated to form a steady steam/water flow in a system of a condenser 3 to a sampling rack. A device 23 is connected through the upper branch 5 of the condenser 3 and a condenser 4 is filled with a gas of normal to several atmospheres beforehand. At the time when purging of a sampling tube 2 is finished, a valve 6 is closed to prevent the reverse flow of downstream water of the condenser 3 from being produced to open a valve 7 so as to take the steam in the condenser 4. The inner pressure is monitored by a pressure gauge 10 to close the valve 7 at the time when it becomes specified pressure so as to open the valve 6. A time is measured from the time when the valve 7 is opened or closed to perform exact time assessment.

Abstract: PURPOSE:To make it possible to polarize beams, differing in wavelength, propagating in optical fiber, by combining an optically active body with a birefringent crystal plate. CONSTITUTION:From laser beams of lambda1 and lambda2 in wavelength having propagated through optical fiber, the same linear polarized components are extracted by polarizer 8 and then changed into linear polarized component beams, whose polarization surfaces cross at right angles each other, by crystal optically active body 9 selected with crystal thickness (l) given a rotation angle difference of 90 degrees. Those component beams of lambda1 and lambda2 in wavelength are caused to strike birefringent crystal plate 10 of calcspar, etc., with its optical axis 11 in parallel to the polarization surface of either one. As a result, one component beam travels straight and the other is refracted, so that laser beams of lambda1 and lambda2 in wavelength will be projected being separated with high precision.
