Title: Chain case for wheel driving roller chain
Inventor: TOMINAGA NOBUYOSHI
IPC: F16H57/035
Filed: 1979-02-28
Abstract: PURPOSE: To prevent wear due to contact of a roller chain by a method wherein a projection stretching along the chain is provided on the inside surface of a case on the inside and/or outside of the rollers of the chain.  
     CONSTITUTION: During movement of a roller chain 7 in a chain case, vibration or slackening of the chain 7 causes the rollers 9 of the chain 7 to contact a projected stringer 29 provided on the inside surface 28 of the middle portion case. On such occasion, the rollers 9 rotate upon contact with the stringer 29 substantially without sliding, since w they are each rotatable relative to a pin 8. Therefore, there occurs little wear between the stringer 29 and the rollers 9, and the portions of the inside surface 28 of the middle portion case other than the projection 29 can be kept unscathed.

Filed: 1996-02-09
Abstract: PROBLEM TO BE SOLVED: To prevent a battery from catching a fire or puncturing, upon the occurrence of the collapse thereof and the subsequent fracture of a separator as a power generation element. SOLUTION: When this battery is formed so that a cylindrical electrode group 2 made of positive electrode active material, a separator 8 and a negative electrode active material is housed in a negative electrode can 10 and the open end of this electrode can 10 is sealed with a positive electrode plate 14 via a gasket 12, a conductive cylindrical member 22 is axially provided inside the electrode group 2, and a conductive columnar member 24 is laid inside the cylindrical member 22 along an axial direction. Also, the lower end of the cylindrical member 22 is fixed and connected to the inner bottom of the negative electrode can 10, while the upper end of the columnar member 24 is fixed and connected to the lower surface of the positive electrode plate 14. In this case, when the battery is collapsed, the cylindrical member 22 and the columnar member 24 come in contact with each other.  As a result, even when the separator 8 is broken and the positive electrode active material and the negative electrode active material come in contact with each other, a majority of shortcircuit current flows to the contact part of the cylindrical member 22 and the columnar member 24. The shortcircuit current flowing across the contact part of the active materials is thereby restrained. According to this construction, the battery can be prevented from catching a fire, puncturing or the like.

SOLUTION: Water discharged from a vortex pump 4 is supplied into the inlet 21 of the nozzle part 26 of a vacuum generator 11 and, when this water is blown out to a vacuum generation room 23, the water quickly passing through this vacuum generation room 23 is supplied from the inlet 24 of a nozzle receiver 27 into a pipe-like passage. Then, the water flowing out from the nozzle part 26 to the nozzle receiver 27 causes a vacuum generation phenomenon and makes a vacuum container vacuum via a vacuum drawing joint part 25 and the pipe-like member. The water supplied into the nozzle receiver 27 is discharged from an auxiliary pipe outlet 22 and then discharged into a storage tank 1.  Since the water temperature of stored water 2 is increased at this time, a part of the stored water 2 sucked up by the vortex pump 4 is dropped to a cooling water panel 8 and then cooled by an air flow from a cooling fan 17.
