摘要:
A liquid (L) sealed in a first mounting member (11) of an anti-vibration apparatus (10) contains a first liquid and a second liquid that are mutually insoluble, the second liquid having a higher vapor pressure and a lower weight percentage (weight %) included in the liquid than those of the first liquid. In the anti-vibration apparatus, the size of a generated abnormal noise can be reduced without complicating the structure and deteriorating a damping performance.

A vibration isolator which is capable of stably opening and closing an orifice is provided at low manufacturing cost. A plunger for opening and closing an idle orifice is disposed in a manner that is slidably engaged with the inner wall surface of an orifice-forming member. A shaft portion extending downward is formed in the central portion of the plunger. A convex portion which is formed with a through-hole in which the shaft portion is slidably is provided on the bottom of the orifice-forming member so as to provide a bearing portion. The shaft portion of the plunger and the bearing portion of the orifice-forming member constitute a guide member for guiding the reciprocating motion of this plunger.

A high-density N-type diffusion layer 116 formed in a separation area 115 makes it possible to reduce a collector current flowing through a parasitic NPN transistor 102. Thus, a normal CMOS process can be used to provide a driving circuit and a data line driver which make it possible to improve resistance to possible noise occurring between adjacent terminals, while controlling a chip size.

A vibration isolating apparatus is provided which can reduce the manufacturing costs thereof. A space defined by an elastic body and a partitioning member 28 forms a main liquid chamber 30. A non-return valve 34 is provided which allows flow-in of liquid only from the main liquid chamber 30 side via a pass-through hole 24A of an upper member 24 forming the upper portion of the partitioning member 28. A plunger 36 is disposed within an annular rib 24B of the upper member 24 so as to be fit with the inner wall surface of the annular rib 24B in a slidable manner. A coil spring 38 for urging the plunger 36 upward is disposed between the plunger 36 and the bottom surface central portion of a lower member 26 forming the lower portion of the partitioning member 28.

A discharge capacity retention of a non-aqueous secondary battery is enhanced by incorporating into its non-aqueous electrolytic solution a small amount of a substituted diphenyldisulfide derivative in which each of the diphenyl groups has a substituent such as alkoxy, alkenyloxy, alkynyloxy, cycloalkyloxy, aryloxy, acyloxy, alkanesulfonyloxy, arylsulfonyloxy, alkoxycarbonyloxy, aryloxycarbonyloxy, halogen, CF3, CCl3, or CBr3. Preferably, a small amount of methyl 2-propylcarbonate, 2-propynyl methanesulfonate, 1,3-propanesultone, divinylsulfone, 1,4-butanediol dimethanesulfonate or cyclohexylbenzene is further incorporated.

A torque rod (1) has two elastic bushes (2, 3) to be mounted respectively to a vibration-generating side and a vibration-receiving side, and a connecting rod (4) connecting the two elastic bushes (2, 3). The actively controlled vibration cancellation means (5) is an actuator including: the shaft (5a) having two opposite ends mounted to the connecting rod (4) and extending in an axial direction of the connecting rod (4), the mass member (5b) shaped in a tube to surround the shaft (5a); a coil (5e) and a winding core (5f) fixed to the shaft (5a) in the tube-shaped mass member (5b); a permanent magnet (5d) mounted to an inner peripheral surface of the tube-shaped mass member (5b) or the shaft (5a), and a connecting member (5c) for connecting at least one end of the tube-shaped mass members (5b) to the shaft (5a).

A first insulating film is formed on a semiconductor substrate, an interconnect groove is formed in the first insulating film, the inside of the interconnect groove is filled with a metal film, thereby forming a first interconnect. Then, a protective film is formed on the first insulating film and the first interconnect, and the surface of the protective film is exposed to reactive gas, thereby forming a reaction layer on an interface between the first interconnect and the protective film.
