An miniaturized accelerometer having a narrow bandwidth and behaving as a switch sensitive only to low frequencies such as contained in earthquakes includes: a unbalanced see-saw beam assembly composed of beams 2 and masses 3 at opposite ends of the beams 2. The beams 2 have their suspension at a location with slightly different distances from the masses 3 along a line parallel to and vertically offset from the line connecting centers of gravity of the masses 3.

A suspension system for a vehicle which has a hydraulic cylinder that extends and retracts in accordance with a change in the distance between a vehicle body and an axle to vary the volumetric capacity of a working chamber defined therein, an accumulator connected to the working chamber in the hydraulic cylinder, a control valve controlling the flow rate of oil charged into and discharged from the accumulator and the hydraulic cylinder, and a vehicle level sensor detecting a change in the above-described distance. The suspension system further has a control unit that controls the control valve, on the basis of a flow control signal obtained by multiplying the detected signal from the vehicle level sensor by an amplification factor, so as to restore the vehicle to a neutral state. The control unit is arranged to increase the amplification factor when the amount of the extension or retraction of the hydraulic cylinder is close to the extent of the full stroke thereof. When the vehicle is running on a normal road surface, the suspension system absorbs any changes in the road surface, thereby stably maintaining the attitude of the vehicle body, and in the case of large irregularities, it is possible to prevent full rebound or full bump which would otherwise occur when the hydraulic cylinder performs a full-stroke operation.

The invention provides for a lithium secondary battery using a non-aqueous solvent wherein the anode material is prepared by the pyrolysis of organic compound starting materials obtained by reacting at least one conjugated polycyclic compound with a nitro compound or with a nitrating agent. The anode material contains at least the elements carbon and nitrogen, the nitrogen content ranging from 0.5% to 6% by weight. Eighty percent or more of this nitrogen is bound to carbon by either C--N or C.dbd.N bonds. The ratio of the intensity of the x-ray photoelectron spectroscopy ("XPS") peak observed for the anode material at 401.2.+-.0.2 eV to the intensity of peak observed for the anode material at 398.8.+-.0.4 eV is 1.0:1 or more.

In a closed type thermal power generation plant, the fuel is supplied in the combustor and burnt therein in the presence of oxygen, instead of air. The combustion gas mainly including water and carbon dioxide is delivered from the combustor into the turbine. A turbine exhaust gas is fed into the waste heat boiler to carry out heat exchanging operation therein and an exhaust gas mainly including water component and carbon dioxide from the waste heat boiler is fed into the condenser. The gas component mainly including the carbon dioxide is separated from the condensate in the water-gas separator and may be fed into the combustor in a compressed state, or the separated gas component may be recovered externally to the plant without emitting the same into the atmosphere. The separated condensate is fed into the waste heat boiler to be subjected to heat exchanging operation therein to generate superheated steam which is to be fed into the combustor, or may be recovered externally.Further, a steam turbine may be connected to the waste heat boiler and generator. A condensor may then be connected to the steam turbine and waste heat boiler so that the steam turbine, condenser and waste heat boiler constitute a closed cycle.

A disc brake assembly includes a mounting member and two brake pads mounted on the mounting member on opposite sides of a disc to be acted upon the brake pads. The brake pads are mounted on backing plates which have circumferential ends disposed in facing relationship to torsion-resisting surfaces of the mounting member. The torsion-resisting surfaces have circumferentially extending projections which engage the backing plates in a manner resisting radial outward movement of the brake pads in response to frictional braking forces.

An apparatus has a hand shaft formed of synthetic resin which has a first hand shaft portion and a second hand shaft portion having an insertion hole into which the first hand shaft portion is inserted to be rotatable. The first hand shaft portion is formed in a columnar shape by molding with the synthetic resin containing fiber-like reinforcing materials. In the synthetic resin forming the first hand shaft portion, the longitudinal axes of fiber-like reinforcing materials are oriented to be consistent with the longitudinal axis of the first hand shaft.
