Title: Secondary battery
Inventor: SHISHIKURA RIICHI
IPC: H01M10/20
Filed: 1986-05-26
Abstract: PURPOSE:To obtain high battery performance with good reversibility for charge and discharge, very low self discharge factor and high energy density, by using polyaniline as negative electrode active material, lead dioxide as positive electrode active material and forming the electrolyte by sulfuric acid water solution. CONSTITUTION:In secondary batteries which are constituted by positive electrodes, negative electrodes and electrolyte as main elements, the secondary battery in the caption is the one consisting of polyaniline as the negative electrode active meterial, lead dioxide as the positive electrode active material and sulfuric acid water solution as the electrolyte. In the case using the polyaniline (PAn) as the negative electrode, necessary amount of use of the sulfuric acid for the same amount of reactive electricity will be a half of the case that is using some other materials. This shows that variation in the liquid concentration is little on charging or discharging, causing many advantageous respects such as a little variation in conductivity, etc., and particularly, the matter that less necessity of the liquid quantity is very advantageous in the case that the battery is made in a closed type and also, the energy density of the total battery can be dreveased.

Title: Charge recorder of battery
Inventor: YAMADA YOSHIMITSU
IPC: G01R31/36
Filed: 1982-07-09
Abstract: PURPOSE:To perform accurate charge recording without exerting any influence of power consumption for the recording upon a battery, by counting charging duration by a counter through a timer, and the frequency of charge by a counter which responds to a battery voltage while a charging period is detected, and performing power-on control through a relay. CONSTITUTION:When a charge CHG is set to a battery BAT, the relay RY1 is energized by a switch MS1 and a transistor (TR) 4 to power-on a charge recorder. Then, a TR9 is controlled by the high-level output in specified-intervals of the timer IC6 which is set and reset through a comparator IC4 while the charge period wherein the charging voltage by an operational amplifier IC5 and a comparator IC3 exceeds a specific value is detected, and the counter T2 counts the charge time. Similarly, the counter T1 driven once the voltage of the battery BAT reaches 80% of the charging voltage counts the frequency of charge, and is powered off by the TR4 which turns on once the charging is completed. Consequently, the accurate charge recording is carried out without exerting any influence of the power consumption upon the battery.

IPC: F23N1/02
Filed: 1979-09-18
Abstract: PURPOSE:To accomplish high-load, high primary combustion with short flame, by drawing primary air through combined use of the suction effect exerted by the injection pressure of gas and that exerted by the suction pressure of a fan. CONSTITUTION:Since the air volume of a fan 9 is controlled by a combustion detecting element 21 consisting of a frame rod and others such that gas is combusted at a constant air-fuel ratio, primary air is drawn by the ejector effect exerted by the injection pressure of gas ejected from a gas nozzle 22 and also by the suction pressure of a fan 9.

Title: Refrigerating device
Inventor: SAWAI KATSUYUKI
IPC: F25B47/00
Filed: 1988-05-16
Abstract: PURPOSE:To effect optimum defrosting regardless of an atmospheric condition, by a method wherein a branch passage is provided in the suction pipe of a compressor provided with a heat accumulating tank in the discharging pipe thereof through a changeover valve equipped with a control means and is connected to the downstream side of the changeover valve so as to be capable of effecting heat exchange in the heat accumulating tank while an atmospheric condition detecting means is provided. CONSTITUTION:When a low atmospheric temperature is detected by an atmospheric temperature detector 52 or a discharging gas temperature detector 54 upon effecting defrosting operation, suction gas is distributed into a compressor 1 from an evaporator 4 through a changeover valve 51 and a branch passage 50 while the suction gas is heated by a heat accumulating tank 40. Accordingly, hot gas from the compressor can be heated and the high-temperature hot gas can be introduced into the evaporator 4 whereby the evaporator can be defrosted in a short period of time even when heat loss is generated in the compressor or the like by the low temperature atmosphere. On the other hand, when a high atmospheric temperature is detected, heating of suction gas in the heat accumulating tank through the branch passage is stopped whereby unnecessary heating is eliminated and the overload operation of the compressor may be avoided. Accordingly, the optimum defrosting may be effected regardless of an atmospheric condition.

Abstract: PURPOSE:To eliminate the need for a capacitor mounted at the outside of a clamp IC by providing a current mirror reflecting a differential output current of a multiplier, a correction current source correcting B-Y, R-Y achromatic color levels and a means stopping them for a blanking period. CONSTITUTION:In the absence of correction by a correction current source 4, a B-Y signal is obtained from a cross point between resistors R1 and R2 and an R-Y signal is obtained from a cross point between a resistor R2 and a current mirror 3.

Moreover, the operation of the multiplier 2 and the correction current source 4 is stopped for the blanking period by using a pulse from a blanking pulse source 8. In this case, the output of the current mirror 3 and the correction current source 4 is zero and a bias voltage equivalent to an achromatic level is outputted.
