Patent JP-H0244680-A (JP)
Title: Constant temperature heater
Inventor: SAWADA KAZUMI
IPC: C09K5/00
Filed: 1988-08-01
Abstract: PURPOSE:To facilitate the change of set temperature and simplify the mechanism by receiving water or hydrophilic fluid.lipophilic fluid emulsion in a heating part and providing in an adjacent radiating part an inner wall surface to which the evaporated gas effects heat transfer with condensation. CONSTITUTION:When a current from a power supply 16 is fed to a heater 10 to flow therethrough, emulsion 13 is heated to produce bubbles and water is evaporated from the surface of the emulsion 13 and the produced water vapor is moved upward to enter a radiating part 12 adjacent to a heating part 11 and condensed into water at the wall surface 17 in the radiating part 12. Meanwhile, the evaporating latent heat is given to the inner wall surface 17 of the radiating part 12 through evaporation-condensation process, and condensed water returns to the lower heating part 11 along the inner wall of a pipe constructing the inner wall surface 17 of the radiating part 12, and after being homogeneously mixed in the emulsion 13 in boiling state, heated again to produce vapor. In this manner, by utilizing the heat transfer with condensation of evaporated gas in combination, the mechanism can be simplified and the temperature of the radiating part 12 can be arbitrarily set by changing the composition of the emulsion 13.

Patent JP-H0241968-A (JP)
Title: Hydraulic boost apparatus
Inventor: KOBAYASHI MICHIO
IPC: B60T13/14
Filed: 1988-08-03
Abstract: PURPOSE:To obtain good operation feeling by selectively switching the first passage and the second passage having a pressure regulating valve for reducing pressure at a designated pressure reducing ratio, which are disposed parallel to each other, by a selector valve and communicating the main power chamber and the subsidiary power chamber through the selected passage. CONSTITUTION:When the second passage 65b is selected by a selector valve 66, a main power chamber 47 communicates with an orifice 67 through a pressure regulating valve 68. Similarly to the case where the first passage 65a is selected, when liquid pressure is introduced into the chamber 47, a power piston 6 is operated. Further, the liquid pressure introduced in the chamber 47 is introduced through a valve 68 and an orifice 67 into a subsidiary power chamber 50. In this case, the liquid pressure is introduced into the subsidiary power chamber 50 later than the chamber 47 by the orifice 67. Accordingly, when the input is stopped at the intermediate load point, even after the output comes to the value determined depending on the servo ratio of the input, the liquid pressure in the chamber 50 is still increased gradually. The final output is, however, smaller than the output in case of selecting the passage 65a. Thus, the after-effect amount can be changed.

Title: Electrochemical secondary cell
Inventor: RAINAA BITSUTEIIN
IPC: H01M4/02
Filed: 1991-08-02
Abstract: PURPOSE: To provide an electrochemical secondary battery with high energy density by a method wherein a charge and discharge mechanism relies on intercalation or deintercalation between Li<+> ions in a positive and negative electrode material, and wherein an electrode structure ensures high cycle stability and good chemical resistance to an electrolyte. CONSTITUTION: A positive electrode mostly composed of lithium manganese spinel represented by LiqMxMnyOz (0<x<0.6, 14<y<2.0) can contain, for example, up to 30% Co as a metal M together with Mn. A negative electrode basically consists of carbon products, manufactured from organic compound by heat decomposition, as host material of Li<+> ions. A density of Li in a spinel grid is limited in such a manner that the value of a parameter (q) is in the range of 0 to 1.3, thus producing lithium manganese spinel having a low lithium content as positive electrode material. At the time of discharging a secondary battery, this spinel discharges most of its battery capacity at a battery voltage of 3V or more, and contributes to high cycle stability.
