Title: Discharge valve device
Inventor: KAWASHIMA KENICHI
IPC: F16K15/16
Filed: 1979-06-04
Abstract: PURPOSE: To improve volumetric efficiency by forming a concaved grooved surface at a little interval from the surface, on the contact surface with the valve plate of a valve receiving plate.  
     CONSTITUTION: On the contact surface with the valve plate 31 of a valve receiving plate 33, a groove surface 48 is formed, a little concaved from the contact surface between the both side edge parts 53 and 54 along the longitudinal direction from the vicinity of the fixed part by a bolt 39 to the free end, leaving both side edge parts 53 and 54. Therefore, if the valve plate 31 is lifted, the oil between the valve plate 31 and the valve receiving plate 33 is pushed out along the groove surface 48, and if the valve plate 31 is separated from the valve receiving plate 33, the contact surface between the valve plate 31 snd the valve receiving plate 33 is small, and the adhesive force can be neglected, so lag is not generated in valve plate 31 opening and closing actions. Thus, the weak point of volumetric efficiency reduction due to lag of valve plate 31 opening and closing operations can be dissolved.

Filed: 1987-03-25
Abstract: PURPOSE:To restrain rapid generation of carbon monoxide, to prevent slopping and to improve yield of molten steel and efficiency of operation by predicting the timing, when oxidizing degree of slag becomes to more than the prescribed value by rising, and charging deoxidizing agent before this timing. CONSTITUTION:Variation of the oxidizing degree of the slag during blowing in a converter with the lapse of time is beforehand grasped, and based on this, the timing, when the oxidizing degree of the slag is risen and reached to the prescribed value, is predicted and the deoxidizing agent is added into the slag before this timing. By the deoxidizing agent, oxygen content in the slag is fixed and it is prevented that the oxidizing degree of the slag becomes to more than the prescribed value. In this way, when the slag is deoxidized, as the excess oxygen in the slag is reduced, the rapid generation of gaseous carbon monoxide is restrained and the slopping can be surely prevented.

Abstract: PURPOSE: To prevent a terminal equipment from recognizing line abnormality by preparing and sending out a code the same as a synchronization code when the transmission of data is interrupted by the decline of a reception electric field in a mobile station or a base station during communication. CONSTITUTION: When the reception electric field of a radio communication part 15 in the mobile station 12 radio-connected to the base station 26 is weakened and outgoing data transmission is interrupted, a mobile station side switches the route of the data to be sent out to a DTF I/F 13 from a synchronization code discrimination circuit 14 to a synchronization code send-out circuit 16 at this time. Then, a control station 21 sends out the synchronization code of incoming data from the synchronization code send-out circuit 24 through a line I/F to a cable line similarly for the cable line.  In such a manner, by sending out the synchronization code the same as the synchronization code to be transmitted at normal time as a substitute from the base station to the cable line and from the mobile station to be portable information terminal when the data transmission is interrupted by the decline of the reception electric field, synchronization is maintained when the data transmission is interrupted.

Title: Method for controlling load balance of bridle roll and device therefor
Inventor: YAMAZAKI TAKUYA
IPC: B21C51/00
Filed: 1997-03-24
Abstract: PROBLEM TO BE SOLVED: To eliminate the slippage without reducing tension difference in the whole bridle rolls by raising the loading tension in the remained rolls by the lowered quantity of the loading tension of a roll developing the slippage so as to be uniformly shared and keeping the difference between the inlet side tension and the outlet side tension. SOLUTION: The speed of motor M1 -M4 for driving each roll R1 -R4 of the bridle rolls 10 is detected by a detector 12 to detect the development of slippage from this output power. The loading tension is calculated by a programmable controller (PLC) 14 and the necessary indication is given to each motor M1 -M4 . In such a way, related to the roll developing the slippage, the loading tension is lowered. Together with this, the lower quantity of the loading tension of the roll developing the slippage is uniformly shaped by raising the loading tension in the remained rolls. Then, the difference between the inlet side tension and the outlet side tension is kept. By this method, in the case the slippage develops, the tension difference between the inlet side and outlet side of the bridle rolls can be kept.
