  • Patent number: 10446838
    Abstract: Cycle characteristics of a nonaqueous secondary battery are to be improved. An active material including: a first active material that contains a nano silicon produced by heating a layered polysilane represented by a composition formula (SiH)n and having a structure in which multiple six-membered rings formed from silicon atoms are connected; and a second active material that contains a graphite, is used in a negative electrode. With this, expansion and contraction due to stress during charging and discharging can be mitigated, and thereby cycle characteristics improve.

  • Publication number: 20110056370
    Abstract: The variable displacement swash plate compressor includes a housing, a drive shaft, a swash plate, a piston, a bleed passage, a supply passage and a low-melting member. The housing has a cylinder bore, a suction chamber, a discharge chamber and a crank chamber. The swash plate is supported in the crank chamber by the drive shaft and inclination angle of the swash plate is adjustable. The piston is reciprocally movably received in the cylinder bore. The bleed passage is formed in the housing in communication with the crank chamber and the suction chamber. The supply passage is formed in the housing in communication with the discharge chamber and the crank chamber. The low-melting member is disposed in the bleed passage so as to restrict fluid flow therethrough and has a lower melting point than the housing. When the low-melting member is melted, an opening of the bleed passage is increased.
