Title: Method for operating top and bottom blown converter
Inventor: KAWASAKI NORIO
IPC: C21C5/28
Filed: 1986-01-16
Abstract: PURPOSE:To advantageously recover a converter gas enriched with CO by executing flux injection with bottom blowing in the initial and end periods of blowing and controlling slag forming in the middle period thereby adjusting the height of slag forming. CONSTITUTION:The flux injection from a bottom blowing tuyere is executed in the initial and end periods of blowing when the concn. of CO is low to suppress the slag forming.

The state judging circuit 6 sends a control signal to reduce the frequency of the output clock 9 of the VCO until then successively by receiving the judging signal of an area other than a zero area, the detecting signal of phase inversion, and the flag signal. Thereby, it is possible to obtain a phase locked loop circuit without generating the slipping phenomenon of the clock of the VCO and with high pull-in speed.

Title: Laminated ceramic electronic parts
Inventor: OMORI NAGATO
IPC: H01G4/12
Filed: 1997-01-17
Abstract: PROBLEM TO BE SOLVED: To improve the reliability of laminated ceramic electronic parts by preventing the deterioration of the function of a ceramic layer by adjusting the minimum thickness of the ceramic layer to a specific percentage of the average thickness of the ceramic layer or thicker. SOLUTION: In a laminated ceramic capacitor, the ratio of the minimum thickness t2 of a ceramic layer 2 to the average thickness t1 of the layer 2 is controlled to >=80% by adjusting the ruggedness of the boundary surfaces between the layer 2 and internal electrodes 1 so that the ruggedness may not become larger. In order to suppress the ruggedness of the boundary surfaces between the layer 2 and electrodes 1, the green sheet of the ceramic layer 2 is formed by using ceramic particles having small particle sizes or ceramic slurry having high dispersibility between the ceramic particles and a binder or the internal electrodes 1 are formed by using metal particles having small particle sizes. Therefore, the deterioration of the breakdown voltage of the capacitor can be prevented even when the average thickness t1 of the layer 2 becomes <=5μm.

IPC: A63F7/02
Filed: 1997-01-17
Abstract: PROBLEM TO BE SOLVED: To reduce fatigue of the player's eyes even if he stares at the display screen with expecting a jackpot. SOLUTION: A screen of a LCD panel 16i of a special pattern display device 16 is configured from a pattern screen displaying special patterns, a background screen displaying a background image and a foreground screen positioned in the front. The special pattern display device 16 is designed to change the transmittance of the foreground screen or the pattern, or the contrast of the pattern screen and the background depending on the communication data sent from the MPU 12 periodically. When a pachinko ball passes through a starting port, the pattern displayed at the LCD panel 16i is changed at a high speed and the transmittance of the foreground screen is reduced, or the transmittance of the pattern screen is increased.  By this, since the visibility of the pattern changing at a high speed is reduced, even if a player stares at the display screen, the fatigue of his eyes can be reduced. Or, if the contrast of the special patterns and the background is reduced during the high-speed changing of the patterns, the same effect can be attained.
