摘要： In a liquid fuel cell including a plurality of series-connected unit cells each including a fuel electrode and an oxidizer electrode disposed opposite to each other with an electrolyte layer being interposed therebetween, a fuel chamber disposed adjacent to the fuel electrode, and an oxidizer chamber disposed adjacent to the oxidizer electrode, and fuel tanks supplying liquid fuel to the fuel chambers, at least two vertically-spaced passages permitting communication of the fuel tanks with all of the fuel chambers are provided so that one of them serves as a passage for liquid fuel while the other serves as a passage for gas produced at the fuel electrodes, the liquid fuel in an amount smaller than the tank volume is charged in each of the fuel tanks to leave a non-charged space, and gas vent ports provided with gas liquid separating means are disposed midway of the passages and/or on the tank wall portions corresponding to the noncharged spaces defined in the fuel tanks. The liquid fuel cell can satisfactorily generate power at whatever attitude, and gas produced at the fuel electrodes can be vented to the exterior of the cell without leakage of liquid fuel.

摘要： A distributor for an internal combustion engine includes a housing in which a distributor rotor is supported on a shaft for distributing a generated high voltage to ignition plugs through electrodes, and a distributor cap covers electrical devices of the distributor. The distributor cap of an insulating material is composed of an inner distributor cap and outer distributor cap of a high strength material space is formed between the walls of outer distributor cap and inner distributor cap for preventing dewing. A number of T-shaped projections may be provided along an inner surface of the outer distributor cap for defining the space, with the projections being fixed to the inner distributor cap or a spacer may be sandwiched between the inner and outer distributor caps.

摘要： PURPOSE:To enable shortage of a shield layer by employing high resistance paint containing a binder, a silicon carbide, and silicon carbide whisker added thereto to provide non-linear resistance properties even in low electric field range. CONSTITUTION:A coil conductor 2 is wound on a stator core 1, and low resistance corona shield layer 4 and high resistance corona shield layer 5 formed with carbon paint and the like are formed through an insulating layer 3 thereon. The layer 5 is so formed, for example, as to wind to superimpose half to half while coating silicon carbide paint on glass cloth tape, and mixed with silicon carbide whisker in this case. Thus, it can provide non-linear resistance properties even in low electric field range so as to sufficiently alleviate the electric field even in short corona shield layer.

摘要： PURPOSE:To retain a lubricant for a long period of time and reduce wear against repeated sliding under a surface pressure employing a glass-fiber-reinforced plastic sheet having concave parts for retaining lubricant on the surface thereof and coated with a proper lubricant. CONSTITUTION:A glass-fiber-reinforced plastic sheet having concave parts formed on the surface thereof for retaining a lubricant is coated with a lubricant such as perfluoropolyether for use as an insulating slide sheet. For example, when it is applied to the field coil, the one coated on one side with a lubricant is used as a layer insulator to be provided between coil conductors. At the same time, for a point requiring thicker insulation such as the insulating sheet between the field core 5 and the coil 4, it is combined with a reinforcing body 7a made up of a metal sheet to form an insulating slide plate 7b. In this manner, the insulating sheet can reduce the wear even undergoing a protracted sliding under a surface pressure.

摘要： PURPOSE:To detect with good sensitivity the deterioration of the coil insulation by providing a measuring electrode only on a flat surface of the coil adjacent to the coil end exit from the slot for measurement thereof. CONSTITUTION:A measuring electrode 17 is installed in a uncoated portion 18 of the flat surface of a coil end formed by removing a part of a low resistance corona shield coating 15 with a gap to said coating 15. A switch 20 and a detector 21 are connected to said electrode 17 via a lead wire 19 whereby the deterioration of the insulation layer can be detected through closing of the switch 20 and adding of the potetial to a coil conductor 2 for measurement of Tandelta0 of the insulation layer at the flat surface portion where the measuring electrode 17 is installed.

摘要： PURPOSE:To prevent the charge current of a field relaxation layer from partially concentratedly being applied by setting up a mean pressure zone with the resistance value which is lower than that of a low resistance corona shielding layer on the field relaxation layer which is adjacent to the low resistance corona shielding layer. CONSTITUTION:The ends of the low resistance corona shielding layer set on the insulated layers 5a and 5b of the winding ends 3a and 3b in a stator winding are inclined by theta so as to be opposed to each other and mean pressure zones 9a and 9b with the resistance value which is lower than that of the low resistance corona shielding layers 6a and 6b are set on the field relaxation layers 7a and 7b which are adjacent to 6a and 6b. The angle of mean pressure zone is smaller than the angle alpha of equipotential line 10 on the surface of the field relaxation layer and larger than the angle theta. Since this permits the charge current applied in the field relaration layer 7 to scatter like the arrow, it can be prevented from being partialy concentratedly overheated.

摘要： PURPOSE:To suppress the vibration of the stator coil, by providing springs urging the wide side surfaces of taper liners which are inserted into the slot so that the stator coil is fixed in the slot. CONSTITUTION:Springs 11, 12 are provided on the wide side surfaces of taper liners to ruge the same. These springs 11, 12 are disposed between the taper liners 9, 10 and the bottom insulator 2 or the insulator 4 under a wooden insert, and the springs 11, 12 are caused to be in a half urging state when the wooden insert 5 is driven in. The returning force of these springs 11, 12 are applied on the end surfaces of the taper liners 9, 10, so that a large force is applied on the side surface of the coil by the sliding of the tapered surface, thus the coil is fixed and the vibration thereof can be suppressed.
