The present invention provides a semiconductor pressure sensor having a glass base and a metal base bonded together satisfactorily so that a silicon diaphragm may not be affected by residual strain, and an intelligent differential pressure and pressure transmitting device employing the semiconductor pressure sensor. The semiconductor pressure sensor comprises a silicon diaphragm (1) provided with a strain-sensitive element, a glass or ceramic base (2) bonded to the silicon diaphragm (1), and a metal base (4) bonded to the glass or ceramic base (2) with a bonding glass (3). The thermal expansion coefficient of the metal base (4) at a temperature corresponding to the strain point of the bonding glass (3) is not greater than that of the glass or ceramic base (2).

A die assembly for use with a tool for bending flat metal stock, and including a pair of elongated plate members in the lower die member each having a surface to support a piece of flat metal stock, the plate members being pivotably connected and maintained approximately 180 degrees apart when a bending force is not applied to the metal stock. A surface of an expandable pressure container is positioned in contact with a plate support member, the pressure within the container being controlled in a manner such that the vertical position of the plate support member is fixed such that the plate members assume a selected angular orientation to enable the tool to form the desired bend in the metal stock.

An input analog image signal is sampled by first and second A/D converters, using first and second sampling clocks of the same period, to obtain digital gradation data. In the case of a double definition display mode, the first and second sampling clocks are made 180.degree. out of phase with each other and the output of the first A/D converter is delayed for one-half period, by which its timing is brought into agreement with that of the output of the second A/D converter, thus obtaining a pair of digital gradation data. In the case of a standard definition display mode, the first and second sampling clocks of the same phase are used to obtain the outputs of the first and second A/D converters as a pair of digital gradation data. The pair of digital gradation data Da and Db is converted by a signal processing part into a pair of analog gradation data Aa and Ab, which is subjected to a serial-to-parallel conversion by a source driver to be supplied in parallel to data lines. In the double definition display mode the gate driver sequentially drives odd-numbered row lines in odd-numbered frames and even-numbered row lines in even-numbered frames. In the standard definition display mode every two adjacent row lines are simultaneously driven in a sequential order.

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.

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.
