Filed: 1982-09-24
Abstract: PURPOSE:To provide a storage battery with a long life by suppressing the corrosion of a positive electrode grid while restricting the increase in a charging current which occurs as a gas absorption area on a negative electrode is increased, by preventing unnecessary oxygen gas to be supplied to a negative electrode active material by means of a lead film coating stretched over the surface of a negative electrode end plate not facing a positive electrode plate. CONSTITUTION:The most part or the whole of one surface of a negative electrode end plate not facing a positive electrode in a group of electrode plates is coated with a film 13 of lead or a lead alloy. When the outside whole surface of the negative electrode end plate most liable to make contact with oxygen gas is coated with the film 13 of lead or a lead alloy, the separation and/or exfoliation of a pasty active material may be sometimes increased during the manufacture of a battery, so that a through hole 14 is made through a junction part between the film 13 and a middle rib 3 to unite air vents at the filling of paste with the paste filled into an adjoining grid section, preventing the paste from being separated during its manufacture. A ratio of the total sectional area of the through holes to the surface area of one surface of the negative electrode plate is desired to be less than 30% from its relationship to the charging current.

Title: Moisture removing method of refrigerating device
Inventor: SAKAKIBARA HISASUKE
IPC: F25B43/00
Filed: 1990-06-26
Abstract: PURPOSE:To obtain high moisture removing effect by a simple constitution utilizing the characteristics of the moisture in refrigerant by a method wherein liberated water, flowing out of a refrigerant evaporator, is retained by a moisture retaining member arranged in a low pressure pipeline at the downstream of the refrigerant evaporator to remove the moisture in a refrigerating device. CONSTITUTION:Refrigerant, having moisture characteristics wherein the saturated moisture concentration of liquid phase is higher than the saturated moisture concentration of gas phase, or R134a, R22 or the like, for example, is used in a refrigerating device 1. Oil, hardly dissolving water, is used for the lubricating oil of a refrigerant compressor 2. As the refrigerant is evaporated in a refrigerant evaporator 6, the concentration of moisture in the liquid is increased. The hydrophilic property of refrigerating machine oil is low and, therefore, moisture, which can not be dissolved by the liquid, is generated as liberated water when the concentration of moisture has exceeded the saturated moisture concentration of the liquid. The liberated water, which flows out of the refrigerant evaporator 6 and flows through a low pressure pipeline 7a, is retained by a moisture retaining member 8 arranged in the downstream of the refrigerant evaporator 6 whereby the moisture, invaded into the refrigerating device 1, is removed to keep the inside of a cycle in the concentration of low moisture while the moisture remover is compact and is prominent in loading property onto a vehicle.

IPC: H02K37/04
Filed: 1991-07-09
Abstract: PURPOSE:To surely take out a rotational output of high torque under high rigidity by equipping a disc member which absorbs the eccentric revolution of a rotor to transmit only a torque generated by the rotation of the rotor to an output shaft. CONSTITUTION:A pin 16 extending in the axial direction of a rotor 14 is fixed in the position at a predetermined radius (r) from the center point RC of rotation in the manner of passing through the rotor 14. When the rotor 14 rotates on its axis relative to the center RC of rotation while revolving eccentrically, the pin 16 also moves in like manner so as to eccentrically revolve clockwise in the circular hole 28 of a disc 26. When the excitation of respective salient poles 12 of a stator 10 makes a round, the pin 16 moves together with the rotor 14 anticlockwise by an angle corresponding to two teeth. Thus, the disc 26 revolves anticlockwise relative to the center SC of rotation of the disc 26 in keeping with the pin 16 so that the eccentric revolution of the rotor 14 becomes the movement of the pin 16 in the circular hole 28 of the disc 26 without operating the disc 26 and only the rotational output by the rotation of the rotor 14 based on a high magnetic attraction is transmitted to an output shaft 20.
