Filed: 1999-03-10
Abstract: PROBLEM TO BE SOLVED: To achieve a reference time control system, a control system, and a time synchronization method for accurate time synchronization by synchronizing the control system based on the propagation delay time of a communication line network. SOLUTION: A reference time control station TS consists of a reference time timer 1 for ticking away reference time, a constant-period timer 2 for reporting with a constant period, and a synchronization means 3 for synchronizing a control system with the reference time based on propagation delay time by the reporting of the constant-period timer 2.

A reading means 31 reads time A of an operation-monitoring station HIS and control stations FCS1 and FCS2. A comparison means 32 adds the propagation delay time to time being read from the control system, compares it with reference time, and notifies it to a setting means 33 if there is any difference.  Then, the setting means 33 sets time where reference time B has been put forward by propagation delay time Δ to the control system.

Title: Linear bush assembly
Inventor: WAKAO SHIGERU
IPC: F16C29/06
Filed: 1999-03-10
Abstract: PROBLEM TO BE SOLVED: To provide a linear bush assembly capable of increasing allowable load in the radial direction with smooth circulation of balls though a linear bush having light movement. SOLUTION: A linear bush assembly is constituted by a shaft 1 and a linear bush 2 combined with the shaft 1. A shallow groove 3 of circular arc section serving as a raceway of balls 5 to come into one point contact with the ball 5 is formed on a surface of the shaft 1. Since the ball 5 abuts to the shallow groove 3 in one point, light movement is obtained similarly to the conventional linear bush. Since the ball 5 comes into point contact with the shallow groove 3 of circular arc section by providing a width of certain degree, allowable load in the radial direction can be increased. Further, the shallow groove 3 has a shallow depth, so that the ball 5 can be deeply held by a cage 6, so that the ball 5 can be surely held by the cage 6.

Title: Production of inorganic fiber
Inventor: TAKAGI RYOJI
IPC: C03B37/05
Filed: 1987-03-18
Abstract: PURPOSE:To reduce the amount of shot (material not to be made into fibers) and to obtain inorganic fibers in high yield, by rotating the first rotary drum is a fiber forming device of multiple rotary drum type at a specific outer peripheral speed. CONSTITUTION:In producing inorganic fibers by a fiber forming device of multiple rotary drum type, the outer peripheral speed of the first rotary drum is made in 60-180m/sec range. When the outer peripheral speed is <60m/sec, difference between the speed and an ordinary outer peripheral speed of 45m/sec becomes small, reduction in shot is lessened and effects are low. On the other hand, when the outer peripheral speed is >180m/sec, a molten raw material is shot to the second drum rather than drawn on the first drum and the same phenomena as those of the first drum occur on the peripheral surface of the second drum. In the case of the multiple rotary drum, the molten material is preferably drawn on each drum uniformly and made into fibers by each drum. Consequently, excessively large speed difference among the drums unfavorably produces unbalance in the molten material drawing in each drum.
