Title: Air velocity controller for air conditioner
Inventor: YABE KATSUHIKO
IPC: F24F13/15
Filed: 1982-07-14
Abstract: PURPOSE:To obtain optimum air quantity and air velocity according to the temperature of a warm air flow, by a method wherein an airflow direction controlling plate and a blow-off port cross-sectional area controlling plate in an interior-side unit are driven by a shape memory alloy the stored shape of which is changed in accordance with the temperature of the blown-off airflow. CONSTITUTION:The interior-side unit comprised of a fan motor 11, a rotating speed controller 12 for the motor 11, a blow-off port cross-sectional area regulator 13, a controller 14 for the regulator 13, a blown-off air velocity controller 15 and the like is provided with an airflow direction controlling assembly 21 rotated with a shaft 22 as a center, the blow-off port cross-sectional area controlling plate 23 rotated with a shaft 23' as a center and a spring 26 formed of a shape memory alloy. In controlling the blown-off air velocity, when the plate 21 is directed downward while the temperature of the airflow is low after starting the operation, the tip of the plate 23 is compressed by actions of a fixed gear 25 and a gear plate 24. Although the spring 26 is forcibly bent at this time, it retains its shape because the temperature is not higher than its operating temperature. When the fan motor 11 is operated at a low speed, air quantity is reduced and the blown-off air temperature is raised. However, since the blow-off port cross-sectional area is throttled, the air velocity becomes relatively high, and warm air of a high temperature can be brought to the floor surface.

Title: Signal processor
Inventor: SATOU HIDEO
IPC: H03M1/14
Filed: 1982-07-14
Abstract: PURPOSE:To expand an input rage even if a highly accurate resistor is not used for the resistor constituting a digital/analog converter (DAC) by compensating the dispersion of the DAC through a microcompter. CONSTITUTION:The input range is expanded by making the minimum bit of the DAC equal to or smaller than the full scale of an analog/digital converter (ADC) through the microcomputer. By controlling the output voltage VDAC of the DAC 50 through the microcomputer system (MSC) 8, the input of the ADC 7 can be converted into a digital value within the full scale and input voltage VIN less than the voltage VREF of a reference power supply 10 can be converted into a digital value by the ADC 7. The converted results can be fetched to the MCS 8 easily. Consequently, the input range can be expanded up to the number that the output status of the DAC 50 is held at maximum. When the DAC is 2-bit constitution e.g., the input range can be expanded by four times.

Title: Method for sterilize water and production of aqueous composition containing surfactant
Inventor: UENO KAZUHIRO
IPC: C02F1/50
Filed: 1999-04-28
Abstract: PROBLEM TO BE SOLVED: To sterilize water easily and efficiently without using a special stelirizer by adding a specified amount of benzoic acid or a benzoate into the water and adjusting its pH to a specified value. SOLUTION: Water is added with 0.3 wt.% of benzoic acid and/or a benzoate, and its pH is adjusted at 4.5 or below. Benzoic acid and the benzoate can be added separately or together. The amount of them to be added is at least 0.3 wt.% of the sterilized water to be obtained. When the addition is below 0.3 wt.%, water can not be sterilized sufficiently. In consideration of the solubility, 0.3-1 wt.% is preferable. The pH of water is adjusted at 4.5 or below. When the pH is above 4.5, the effective sterilization can hardly be obtained, and when the pH is too low, a tank for storing the sterilized water tends to be corroded. Therefore the pH is preferably kept at 3-4.5.
