Title: Bus system and data transfer method in bus system
Inventor: OTA KEN
IPC: G06F13/36
Filed: 1999-07-29
Abstract: PROBLEM TO BE SOLVED: To improve the efficiency of signal transfer on a bus by preparing bus transfer end signals on a bus system exclusively for an address signal and a data signal respectively. SOLUTION: When a 1st bus master 210 sends a bus request signal BR-P1 out, an arbitrating circuit 250 sends a bus grant signal BG-P1 to the bus master 210 to supply an address signal to an address bus. The arbitrating circuit 250 selects, e.g. a DRAM 230 with the address signal and sends a select signal ME-DRAM. When preparations for address signal fetch are made, the DRAM 230 asserts an address acknowledgement signal AA and sends a specific number of address signals from the bus master 210 to the DRAM 230 in order to transfer data. The arbitrating circuit 250 monitors the signal AA and resets the signals ME-DRAM and BG-P1 after the address signals are transferred, thereby sending a bus grant signal BG-P2 to a 2nd bus master 220 having sent a 2nd bus request BR-P2 out.

Title: Initial period operating method for melting in electroslag refining
Inventor: OTSUKA NOBORU
IPC: C22B9/193
Filed: 1986-09-16
Abstract: PURPOSE:To prevent the generation of flashes and molten metal leakage in an initial period of melting and to improve the quality in the bottom of an ingot in an electroslag refining process by packing a yarn-shaped noncombustible material between a crucible and crucible closing body. CONSTITUTION:A high-quality ingot is formed by immersing a consumable electrode into molten slag, melting the consumable electrode by the Joule heat generated in the molten slag when the electrode is energized, removing impurities by the slag refining effect during the fall of electrolytically molten drops in the molten slag and laminating and solidifying the molten drops successively in the water-cooled copper crucible 1. The yarn- or cord-shaped noncombustible material (asbestos yarn) 3 is held packed between the stationary crucible 1 and a stool 2 which is the crucible closing body. A starting block 4 and an igniting agent 5 are installed on the stool 2. The generation of flashes and molten metal leakage between the crucible 1 and the closing body 2 in the initial period of melting is thereby prevented and the penetration of the noncombustible material 3 to the bottom of the ingot after the refining is obviated. The quality at the bottom of the ingot is thus improved.

IPC: G03G15/20
Filed: 1986-09-12
Abstract: PURPOSE:To prevent fixing force from dropping immediately after printing has been started, by carrying cut paper at a longer interval than usual, until a prescribed time elapses after the printing has been stated, or until printing of a prescribed number of sheets is ended. CONSTITUTION:When a printing start instruction is received from a printer control unit after a power source has been turned on, a cut paper laser beam printer starts immediately a printing operation, a heating fixing roller 2 and a press-contacting roller 3 start a rotation, and cut paper 1 is carried at a wider interval than usual. Subsequently, after printing of a prescribed number of sheets has been ended, said interval is returned to a usual interval and the cut paper 1 is carried. In this way, the press-contacting roller 3 is warmed quickly and uniformly, a fall of a surface temperature of the heating fixing roller 2 is reset quickly, and when the cut paper 1 passes through between the heating fixing roller 2 and the press-contacting roller 3, the surface temperature of the heating fixing roller 2 scarcely falls, and it can be prevented that a fixing force of a toner image on the cut paper 1 drops immediately after printing has been started.

Title: Tn type liquid crystal panel
Inventor: MATSUO YOSHIHIRO
IPC: G02F1/1337
Filed: 1988-08-31
Abstract: PURPOSE:To reduce a flicker of a display panel by providing an orienting film on the surface of a display transparent electrode part and equalizing the thickness of the orienting film of an array substrate to that of the material of the orienting film on the side of a counter electrode substrate. CONSTITUTION:A bias voltage which is not specified is generated between opposite electrodes and an initial adjustment by its offset voltage application shifts owing to the temperature variation and time variation of said bias voltage, thereby causing the generation of the flicker (30Hz component). Here, when the orienting films between upper and lower substrates are formed of the same material as thick as each other, a charge accumulation quantity which is near by the orienting films and not a specified one is equalized to a charge accumulation quantity which is on the side of the counter electrode substrate and not a specified one, so that the bias voltage which is not a specified one is not generated. Therefore, the flicker of the panel is reduced without using any special flicker erasure driving method.
