A variable-displacement compressor includes a wobble member for driving a pistons, and a rotation member for wobbling the wobbling member, a first support portion for supporting a wobbling member in such a manner that the angle of wobbling of the wobbling member is variable, and a second support portion for supporting said rotation member in such a manner that the angle of tilt of said rotation member relative to a main shaft is variable. With this construction, unbalanced inertia forces can be reduced greatly, thereby providing the variable-displacement compressor which produces less vibrations and noises.

Nozzle shafts and a nozzle drive mechanism are disposed on the side of a bearing casing and a compressor whose temperatures are lower than that of a turbine, and elements slidable in the radial direction of the turbine wheel are eliminated from the nozzle drive mechanism so that any adverse effects due to oxidization at high temperatures and slide wear can be eliminated. Thus durability and reliability of the device can be improved.

A catalytic structure for treating exhaust gases is provided which is obtained by spraying molten aluminum onto the surface of a substrate such as wire netting, expanded metal, etc. in the presence of oxygen, to form on said surface of a substrate a roughened surface through deposit of fine aluminum particles thereon and also an aluminum oxide layer on said roughened surface, and adhering onto this layer a catalytic substance such as a catalyst for reducing nitrogen oxides.The catalytic structure has a high catalyst-retainability to prevent the catalyst from readily peeling off from the surface even when a mechanical impact is applied thereto. Further it exhibits a superior corrosion resistance even in a corrosive environment containing sulfuric acid; hence it is suitably employed for the apparatuses for treating exhaust gases containing nitrogen oxides and sulfur oxides.

A semiconductor pressure transducer includes a monocrystalline semiconductor diaphragm, the outer edges of which are fixed. When subjected to pressure, the transducer produces radial strains of opposite polarity in a central portion thereof and a portion surrounding the central portion close to the edge of the strain inducing region. The diaphragm contains a plurality of elongated resistances formed of semiconductor material of the same conductivity type which are electrically isolated from the diaphragm, per se. Resistances of an individual set which lie in proximity to one another are combined in the form of a bridge. The longitudinal direction of resistances forming one set of opposing arms of the bridge extend along axes of the same crystal system as the longitudinal direction of the elongated resistances forming the other set of opposing arms of the bridge. However, the longitudinal directions of the separate sets of resistances forming the opposing arms of the bridge lie in directions so that they do not orthogonally intersect each other.

摘要:
An LCD (21) for displaying a plurality of set information items is provided for a digital camera (10). When a plurality of input keys disposed around the LCD (21) are depressed, set information which is displayed adjacent to the input key can be changed. A control portion of the digital camera (10) performs a variety of control operations of the digital camera (10) in accordance with set information. Therefore, the position of the input portion which is used when the setting of the digital camera (10) can easily be understood. Thus, the setting can be changed by performing only a simple operation.

Each of the paired brush devices includes a brush in sliding contact with a commutator, a brush arm holding the brush, and a brush base to which the brush arm is fixed and which has a base hole. The pair of brush devices are disposed such that a line connecting the centers of the pair of brushes inclines in relation to a line connecting the centers of a pair of magnets. Each of the brush arms of the brush devices is disposed on the outside of the corresponding brush base at a location where the brush arm is fixed to the brush base, and one of the brush arms is bent from the outside of the corresponding brush base toward the inside thereof while being passed through the base hole to intersect the brush base.

An electrostatic discharge protection circuit has a bipolar transistor which includes a first diffusion layer of a first conductive type connected with a first power supply and functioning as a base; a second diffusion layer of a second conductive type connected with a second power supply and functioning as a collector; and a third diffusion layer of the second conductive type connected with an input/output pad and functioning as an emitter. An area of a first region of the third diffusion layer which is opposite to the first diffusion layer is larger than an area of a second region of the second diffusion layer which is opposite to the first diffusion layer.
