摘要:
A digital camera capable of readily recognizing the printing-specifying information that has been set. Printing-specifying information is set for digital image data acquired by photographing. When an image for which printing-specifying information has been set is displayed on a monitor provided in the digital camera, the image is displayed along with the set printing-specifying information.

In a digital camera, an image sensor or imaging device is driven in a partial pixel read mode during framing. The resulting image signal output from the image sensor is transformed to image data which can be displayed on, e.g., a display in real time. These image data are sent from the camera in an isochronous mode via a transmission interface and a cable connected to the interface. When a release command is input, the image sensor is driven in a full pixel read mode. Image data generated in this mode are written to a removable memory connected to a card interface or sent in an asynchronous mode via the transmission interface and cable. An image reproducing device is also capable of being connected to the camera by the cable.

A resistance welding power supply apparatus comprises a large-capacitance capacitor for storing resistance welding energy, a capacitor charging circuit, a switching element electrically connected between the capacitor and one electrode of a pair of welding electrodes, and a control unit for the switching element. If the welding current is less than a set current value at a point of time on the leading edge of a clock, then the control unit holds a control pulse for the switching element active or high from that point of time till the time when the welding current exceeds the set current value without being affected by the cycle of the clock. If the welding current exceeds the set current value at a point of time on the leading edge of the clock, then the control unit holds the control pulse inactive or low till a point of time on the leading edge of the next clock.

摘要:
An aluminum nitride composition including an aluminum nitride powder and an aromatic amine-based condensate is provided. In the composition, the aluminum nitride may hardly undergo decomposition even under severe conditions of high temperature and high humidity, and the electrical insulating properties and high thermal conductivity inherent in aluminum nitride powder can be maintained under such severe conditions. Accordingly, this composition is useful as a durable heat-dissipating composition, in particular, as a heat-dissipating coating material, grease or sheet.
摘要:
A device for coding picture data by compression, and a method thereof. By preprocessing, the device calculates a picture activity of one frame of picture data. A quantizing table circuit selects a particular quantizing step matching the picture activity and sets it in a quantizing circuit 32. On a first path, one frame of picture data is fed to a discrete cosine transform (DCT) circuit to be thereby subjected to orthogonal transform. The quantizing circuit sequentially quantizes DC components, low frequency components and high frequency components of the resulting output of the DCT circuit in ascending order of frequency block by block according to a quantizing step set therein. The picture data from the quantizing circuit are coded by Huffman coding while a code counter counts the coded data. The quantizing step set in the quantizing circuit is updated on the basis of the amount of coded data and a target amount of codes. On a second path, the same one frame of picture data is again fed to the DCT circuit to undergo orthogonal transform and compression, as on the first path. The coded picture data are sent to a memory card or similar picture data storing means. A bit distributing circuit produces a bit distribution value block by block. When the output count of the code counter associated with one block reaches the bit distribution value, the DCT circuit, quantizing circuit and Huffman coding circuit are disenabled while an EOB (End Of Block) code is added to the end of the block of coded picture data.
摘要:
A process for producing graphite materials for a negative electrode used in a lithium secondary battery which process includes the steps of packing carbon materials having an average particle diameter of 5 to 50 .mu.m in a plurality of boxes, placing the boxes in a graphitization furnace, subjecting the graphite materials to graphitization treatment, and thereafter subjecting the resultant graphite materials to uniformization treatment by mixing and agitation. The above process is capable of decreasing the influence on the qualitative variation of graphite materials ascribed to packing operation into boxes for graphitization, to the position of the materials in a graphitization furnace, and to bubbling phenomenon or the like through graphitization treatment, and is also capable of stabilizing the qualities of the resulting graphite materials and increasing the productivity.

This agent is used for forming a coating on the inner wall, etc. of a polymerization vessel. Such a vessel is effective in preventing polymer scale deposition, not only in the liquid-phase region but also in the vicinity of the interface between the gas and liquid phases in the vessel, and useful in producing a polymer that shows very few fish eyes and good whiteness when formed into sheets or the like.
摘要:
Image data are recorded in a memory card in a standard DOS-FAT data file structure. When the compression mode is set, original image data is compressed in accordance with a JPEG system, and compressed image data obtained and fixed information in a JPEG header are written in the memory card so as to form a JPEG file. When the uncompression mode is set, the original image data and fixed information in a TIFF header are written into the memory card so as to form a TIFF file. Accordingly, it becomes possible to handle not only compressed image data but also original image data which is obtained in a digital electronic still camera by a lot of types of personal computers.
