Abstract: PURPOSE:To suppress the generation of dissonance vibration by providing a means to relax inertia moment by which an inertial mass of the reciprocating member of the valve system of a cylinder spaced farmost from the center of gravity of at least a power plant is generated, in a power plant having a multicylinder engine and a transmission. CONSTITUTION:A power plant 2A has a reciprocating piston type multicylinder engine 4A and a transmission 6A and the center of gravity G thereof is positioned in the vicinity of the transmission 6A and more rearward than the position of a fourth cylinder. In a valve system arranged at a cylinder head 7, the more a cylinder is located in a position spaced far from the center of gravity G of the whole of the power plant 2A, the more an inertia mass of a reciprocating member is decreased. Inertial loads generated at first - fourth cylinder (distances 11-14 from the center of gravity G) are F#1-F#4 and set to F#1<F#2<-F#3<F#4, and a difference in inertia moment between the cylinders is reduced. This constitution suppresses vibration moment to a low value and reduces the generation of vibration noise of an offensive harmonic comoponent.

Title: Variable displacement type swash plate compressor
Inventor: OTA MASAKI
IPC: F04B39/00
Filed: 1995-07-27
Abstract: PROBLEM TO BE SOLVED: To secure the smooth displacement operation of a swash plate in a simple structure by forming a through hole to permit an inclination displacement of this swash plate extending over the whole control range via a support part which is partially butted to a sleeve at a side to be opposed to a hinge mechanism as holding an axial center between. SOLUTION: In this variable displacement type swash plate compressor, such a moment as making a swash plate 11 be tilted on the basis of compressive reaction or the like, is received by a sleeve 18 being butted to a support part 20a of this swash plate 11, but it follows in the wake of movements of the support part 20a attendant upon the inclination displacement of this swash plate 11, the sleeve 18 is also driven in the same direction on a driving shaft 6, therefore a substantial sliding distance of the support part 20a is contracted to a very little relative displacement to be produced in a gap with the sleeve 18.  Accordingly, wear in the driving shaft 6 is effectively prevented by a conversion to a surface contact sliding motion with the sleeve 18, not to mention sliding wear between both of them to be butted, and thus the smooth inclination displacement operation of the swash plate 11 is surely ensured.

Title: Manufacture of polymeric solid electrolyte
Inventor: IDO SHUICHI
IPC: C08K3/00
Filed: 1989-07-24
Abstract: PURPOSE:To improve ion conductivity by removing a solvent A from a mixed liquid including a predetermined amount of solvents A and B, as well as an ion dissociative salt by means of drying or soaking the solvent A in the solvent B that includes the ion dissociative salt. CONSTITUTION:From a mixed liquid that includes a solvent A that has compatibility with poly arrylate (PAR), a solvent B in which ion dissociative salt is soluble, and as ion dissociative salt, the solvent A is dried and removed or soaked in the solvent B that has ion dissociative salt, so as to manufacture a polymeric solid electrolyte. The solvent B is poorly soluble or non-soluble with PAR, and through the inclusion of the ion dissociative salt, it becomes non-soluble with PAR. The solid electrolyte includes the solvent B and the ion dissociative salt almost uniformly in PAR. Since the ion dissociative salt is dissociated in the solvent B and moves, high ion conductivity is observed. For the solvent B, tetrahydrofuran, 4,4-dimethyl-1,3-dioxane, etc., are used.
