In reproducing halftone dot images, the appearance of moire effect is suppressed by slightly and randomly disarranging the positions of halftone dots to be recorded from the normal position in each unit halftone dot area, or by slightly and randomly distorting the halftone dots.

A metal-ceramic joined article comprises a ceramic member, a thin metal layer joined onto the surface of the ceramic member and a surface layer, formed on the surface of the thin metal layer, having the function to prevent carbon and/or nitrogen diffusing into the thin metal layer. The thin metal layer contains a first oxide film forming element capable of forming a first oxide film having the function to suppress carbon and/or nitrogen from diffusing into the thin metal layer, and the surface layer preferably comprises the first oxide film formed by oxidizing the surface of the thin metal layer before joining.

Provided is a low-cost, highly responsive, and highly durable thermistor material for use in a reducing atmosphere, with which temperature can be measured even under a reducing atmosphere such as a hydrogen gas atmosphere or in a vacuum without the thermistor material being sealed with a glass seal or a metal tube. The thermistor material includes a matrix material made of an insulating ceramic and a non-oxide conductive material, and conductive particles are dispersed around the matrix material to thereby form a conductive path. The conductive particles are preferably dispersed in a network structure around the matrix material. Further, the conductive particles are preferably dispersed discontinuously around the matrix material.

A sensor material for measuring physical parameters capable of configuring a sensor capable of directly measuring a high value of physical parameters such as high stress or high pressure without employing a pressure resistance container. The sensor material for measuring static and dynamic physical parameters includes a matrix made of an electrically insulating ceramic material, and piezoresistance materials which are dispersed in the matrix so as to be electrically continuous to each other.

A composite material is composed of a matrix and dispersed components which form a discontinuous three-dimensional network structure in the matrix. It permits the dispersed components to fully exhibit the characteristic properties without any loss of mechanical properties. A process for producing the above-mentioned composite material includes preparing a raw material powder such that granules of desired shape for the matrix are discontinuously covered with components of desired shape for the dispersed phase, molding the raw material powder into a desired shape, and heating the molded article.

A temperature sensing element includes a thermistor composed of Si-base ceramics and a pair of metal electrodes bonded onto the surfaces of the thermistor. The metal electrodes contain Cr and a metal element α having a Si diffusion coefficient higher than that of Cr. A diffusion layer is formed in a bonding interface between the thermistor and each metal electrode, the diffusion layer including a silicide of the metal element α in a crystal grain boundary of the Si-base ceramics. A temperature sensor including the diffusion layers is provided. Owing to the diffusion layers, the temperature sensor ensures heat resistance and bonding reliability and enables temperature detection with high accuracy in a temperature range, in particular, of from −50° C. to 1050° C.

A collision avoidance judging section is provided which, based on a relative connection between own vehicle and preceding vehicle, carries out a judgment as to whether or not a possible collision is avoidable by operating at least one of a steering wheel and a brake pedal, and a collision avoidance estimating section is provided which, based on the relative connection, carries out an estimation as to whether or not, after expiration of a predetermined time from the time of detection of the relative connection, a possible collision is avoidable by operating at least one of the steering wheel and brake pedal. When the collision avoidance estimating section estimates that the possible collision is unavoidable, a lower braking force is produced, and when the collision avoidance judging section judges that the possible collision is unavoidable, a higher braking force is produced.
摘要:
A command from a host computer is held in a command holding section, and commands set in a register are referenced to determine whether or not the held command involves data transfer. If the command involves data transfer, a switching signal output section outputs switching identifying signals SX and SY to a command switching section. Thus, the command involves data transfer, control is provided by a hardware configuration without using a CPU. Alternatively, when the command involves no data transfer, the switching signal output section outputs an interrupt to the CPU. The CPU interprets the command held in the command holding section to output the switching identifying signals SX and SY to the command switching section.
摘要:
A vehicle environment recognition system comprises an input section for forming an input electronic image of a forward road ahead of a vehicle, and an image processing section for detecting another vehicle ahead or a configuration of the forward road from the image. The processing section prepares a set of integrand images from two or more input images, and produces a new integral image by superposing the integrand images. From information supplied from the input section, the processing section detects a lateral position of the vehicle relative to the road, and adjusts the lateral positions of the integrand images in accordance with the detected lateral vehicle position before the integration to produce the integral image. The recognition system can therefore integrate images without undesirable lateral deviation and detects an object region accurately from the integral image.
