摘要:
A system for maximized utilization of a display memory of a type including 2.sup.n memory elements of equal storage capacity arranged in a block fashion in corespondence with a display screen, each memory element being capable of storing, in a two-dimensional address, the pixel data which includes a predetermined number of bits. The system includes 2.sup.n-m memory groups, each includes 2.sup.m memory elements neighboring with each other on the display screen, an RAS switch connected between an RAS signal line and an RAS terminal of each of the memory elements forming each memory group, and a CAS switch connected between a CAS signal line and a CAS terminal of each of the memory elements forming each memory group. Thus, they can be switched over on a hardware basis to allow the reading of the pixel data from the display memory to be compatible with either one of a monochromatic and color display device, or one of a vertically and horizontally longer display device.
摘要:
A character drawing method for use in a bit map display system in which after sentence data constituted by character code data have been converted into character pattern data, a bit string for forming characters is transferred to a memory for display corresponding to pixels so as to be displayed. In the character drawing method, drawing of the characters is performed through optimum distribution of functions of processings to be executed such that the processings are executed in parallel by a multiprocessor.

A work machine includes a main pole internally including a rotation shaft, a tool unit located at one end of the main pole, and a power unit located at another end of the main pole. The main pole includes a first partial pole, a second partial pole and a joint member that joints them to each other. The first partial pole includes a positioning member. The joint member includes a positioning hole configured to engage with the positioning member and a guide groove extending from the positioning hole. The guide groove is configured to guide the positioning member to the positioning hole and to allow the positioning member to escape in at least a section thereof.

An electroconductive bonding material contains a thermosetting resin, a low-melting-point metal powder which is melted at a temperature equal to or lower than the thermosetting temperature of the thermosetting resin, a high-melting-point metal powder which is not melted at a temperature equal to or lower than the thermosetting temperature of the thermosetting resin and which reacts with the low-melting-point metal powder to form a reaction product having a high melting point of 300° C. or higher during heat-hardening of the thermosetting resin, and a reducing substance which removes an oxide formed on the surface of the high-melting-point metal powder. The total content of the low-melting-point metal powder and the high-melting-point metal powder is 75% to 88% by weight, and the particle size ratio D1/D2 of the average particle size D1 of the low-melting-point metal powder to the average particle size D2 of the high-melting-point metal powder is 0.5 to 6.0. Thereby, an electroconductive bonding material is provided which has good conduction properties and high connection strength even when reflow heat treatment is repeatedly carried out or thermal shock accompanied with a rapid temperature change is applied to the electroconductive bonding material, and an electronic apparatus using such an electroconductive bonding material.
摘要:
The method of the present invention first provides a plurality of representative color points existing on the surface of a gamut (s20), and sets a plurality of boundary lines that connect the plurality of representative color points substantially along the surface of the gamut (s22). The method subsequently defines a plurality of unit faces that are respectively surrounded by at least three boundary lines and arranged substantially along the surface of the gamut (s24), and sets a color plane to cross the gamut (s26). The method successively selects cross boundary lines that cross the color plane among the plurality of boundary lines, determines intersections of the cross boundary lines and the color plane, selects unit faces that cross the color plane based on the selected cross boundary lines, specifies cross lines of the selected unit faces and the color plane by connecting the intersections, and joins the cross lines to extract a contour of a cross plane area obtained by causing the color plane to cross the gamut (s28). This structure enables the contour of a cross plane area, which is obtained by causing a color plane to cross the gamut, to be accurately extracted even when the color plane is arranged at any arbitrary position and in any arbitrary orientation.
摘要:
Flow rates of melt supplied to triple-point regions are controlled in response to detected shapes of lateral side surfaces of a casting and a level of the melt in a basin is maintained constant, whereby high-quality castings are produced.

Cut-out portions or horizontal passages in the form of an inverted T are provided to melt solidified shells grown at triple points at which side seal plates, colling rolls and molten metal are made contact with each other. Pouring holes or slits are provided for inside pouring. Length of the slit in the cast widthwise direction is preliminarily determined so as to maintain temperature distribution in molten bath uniformly. Start of a continuous casting operation is facilitated by movable baffer plates disposed at open ends of the horizontal passage.

Various components of image-forming means such as corona discharger, developing device and cleaning means are arranged around a photosensitive drum. These processing parts and the photosensitive drum are assembled together into a unit which can be detachably mounted into the main body of image-forming apparatus. Such a unit is called process kit. The process kit is provided with a driving connection member for receiving a driving force from the main body. The present invention provides safety means for effectively protecting said driving connection member from shock and impact thereby assuring the utility of the process kit for a long time.
摘要:
In a dual roll type continuous casting machine, molten-metal-pouring passages for feeding molten metal into a molten bath or pool are so disposed and oriented that molten metal is fed toward the side seal plates in the directions tangential to a pair of cooling rolls, whereby only solidified shells formed on the side seal plates at the so-called triple points are effectively melted.

A continuous press apparatus presses an electrode band plate having a band-shaped metal foil collector on which an electrode active material is formed at intervals in a longitudinal direction. The apparatus includes a pair of press rollers, gap adjusting means for adjusting a gap between the press rollers, detecting means for detecting that a rear end of the electrode active material portion arrives at the position between the press rollers, and the gap adjusting means adjust the gap between the press rollers in response to the detection.
