Title: Diagnosing method for display memory
Inventor: KOIBUCHI SHOICHI
IPC: G06F3/14
Filed: 1988-04-18
Abstract: PURPOSE:To improve the availability of a CPU by dividing a memory area of a display memory VRAM into two parts to perform the logical arithmetic of both data written into two divided parts of the memory area and copying the result of said arithmetic into one of both divided memory areas. CONSTITUTION:The same data are written into a VRAM 3 and divided into two pieces. Then the logical arithmetic is carried out to both pieces of data and the result of this arithmetic is copied to one of two divided pieces. The copied data is further divided into two pieces and the similar processes are successively carried out. Therefore a CPU 1 is just required to start a CRT controller 2 and the data to undergo the reading/checking actions of the CPU 1 is cut down to 1/2N of an entire area in case a raster arithmetic circuit is referred to as N. Thus the controller 2 is intent on the generation, arithmetic and transfer of the memory location after receiving once a command. As a result, the controller 2 works only for a period required for its raster arithmetic and therefore the CPU 1 can carry out other processes. Then the availability of the CPU 1 is improved.

IPC: B66B31/00
Filed: 1997-04-11
Abstract: PROBLEM TO BE SOLVED: To clean a turn cleat surface by fixing a cleaning root composed of a first brush contacted with a cleat groove and a second brush contacted with the cleat surface in an attaching plate held between a comb plate and a comb plate arranged directly above a step. SOLUTION: The tips of first and second brushes 8 and 11 fixed in the end part of an attaching plate 7 held between comb plates 4 and 5 provided in a landing 1 are contacted with a cleat groove 3 and a cleat surface 31. When steps 2 and 2 travel to pass the comb plate 4, the cleat groove 3 of the step 2 is slid by the first brush 8 and the cleat surface 32 is slid by the second brush 11 and thereby mud, sand or dusts are eliminated. Thus, since the brush contacted with the cleat groove 3 is provided separately from the comb plate 5, the structure of the comb plate 5 is simplified. Further, the comb plate 5 and the brushes 8 and 11 are separately replaced and thus repairing costs are reduced.

Abstract: PURPOSE:To obtain a small sized and inexpensive capacitor switching device with low electric loss by allowing a switch to bypass a thyristor switch after a capacitor is applied to a power supply with the thyristor switch and using one thyristor switch to capacitors of plural banks. CONSTITUTION:When a voltage impressed to the thyristor switch is zero at a time t2, a thyristor switch 5 is turned on by a control signal outputted from a control circuit so as to apply a capacitor bank 3a to an AC voltage line 1 without any rush current and a switch 2a is turned on at a time t3 so as to commutate the current flowing to the thyristor switch 5 to the switch 2a.
