Filed: 1990-04-27
Abstract: PURPOSE:To ensure transfer of ink to the surface of printing paper by a method wherein the ink is made soluble by friction heat generated by friction between an ink ribbon and a thermal head that is made to produce minute vibration. CONSTITUTION:A metallic plate 4, working for heat radiation and positioning for a head, is connected to a source voltage when printing is made.

Title: Sealed battery and its manufacture
Inventor: SHIRAI IWAO
IPC: H01M6/16
Filed: 1986-05-20
Abstract: PURPOSE:To improve high rate pulse discharge performance and to stabilize production process by arranging a circular insulating layer between the periphery of a separator and that of an electrolyte retention material. CONSTITUTION:A circular insulating layer 8 made of pitch or the like is arranged between the periphery of a separator 3 and that of an electrolyte retention material 4. Thereeby, a somewhat excess amount of electrolyte is absorbed in the separator 3 and the electrolyte retention material 4 and the splash out of the electrolyte in battery assembly is prevented to stabilize battery performance. Since the insulating layer 8 increases adhesion of the separator 3 and the electrolyte retention material 4, the floating out of these materials from a positive case 1 resulting their deformation caused by environmental humidity in battery assembly can be eliminated. Thereby, production process is stabilized.

Title: Ac generator for vehicle
Inventor: UMEDA ATSUSHI
IPC: H02K3/50
Filed: 1998-04-24
Abstract: PROBLEM TO BE SOLVED: To reduce the temperature difference between two coil end groups of a stator winding. SOLUTION: The area in which a first coil end group 31a in the vicinity of rectifiers 5 receives cooling wind from blowers 11, 12 is larger than the area, in which a second coil end group 31b receives the cooling wind from the blowers 11, 12. The wind which has cooled the rectifiers 5 is sent to a first coil end group 31a, existing in the vicinity of electric elements whose temperature becomes high as in the rectifiers 5, so that the temperature of the cooling wind is higher than the temperature of a second coil end group 31b side. By increasing the area in which the first coil end group 31a receives the cooling wind, cooling capability can be improved, and the temperature difference between the first coil end group and the second coil end group can be reduced.

Title: Cooling method of high temperature particulate material
Inventor: NISHIDA TOYOMI
IPC: F28D13/00
Filed: 1981-07-22
Abstract: PURPOSE:To improve the cooling efficiency and consequently make a cooling device smaller by a method wherein cooling tubes, against the upper inner surface of which cooling liquid is sprayed so as to form liquid film throughout the entire inner surface thereof, are imbedded in the layer of the high temperature particulate material. CONSTITUTION:The cooling tubes 9, against the upper inner surface of which cooling liquid is sprayed from spraying nozzles 19 so as to form liquid film throughout the entire inner surface of the tubes 9, are imbedded in the layer 6 of the high temperature particulate material charged from a charging port 3 into the main body 2 of the cooling device 1. Said liquid film is evaporated with the heat transferred through the walls of the tubes 9 from the high temperature particulate material. In addition, air is led from a blower into each tube 9. The air passing through the tube 9 facilitates the formation of the liquid film throughout the entire inner surface of the tube 9, resulting in accelerating the evaporation of the liquid film. As a result, the heat transfer resistance between the wall surface of the tube 9 and the water as cooling medium becomes small, resulting in efficiently cooling the particulate material near the outer peripheral surface of the tube 9.
