Title: Wire-rod rolling mill
Inventor: TAKEDA SATORU
IPC: B21B13/12
Filed: 1999-08-11
Abstract: PROBLEM TO BE SOLVED: To inexpensively provide a wire rod rolling mill capable of extending the range of size-free without increasing the equipment of a rolling mill, excellent in rolling quality such as dimensional precision and suppressing in investment amount. SOLUTION: In this wire rod rolling mill A which is provided with three 4-roll mills arranged in series shifting the reducing direction 45 deg. by 45 deg. and arranged in the last of a continuous finish rolling line Ls for wire rods, among three these 4-roll mills P1, P2, P3, by taking the mill P1 for the 1st pass as an individual motor drive system with a motor M1, the range of size-free is extended. Since the mills P2, P3 for the 2nd and 3rd passes are a common motor system with one motor M2, the number of motors is reduced, the interval between the mills is narrowed, and the rolling quality is improved.

Title: Driving method for liquid crystal element
Inventor: KATAKURA KAZUNORI
IPC: G02F1/133
Filed: 1993-08-23
Abstract: PURPOSE:To obtain the driving method which is hardly affected by threshold value variation due to the temperature distribution, cell thickness distribution, etc., of the liquid crystal element by applying a pulse which is reset into a 1st stable state, a write pulse, a compensation pulse, and a pulse which does not contribute to display in order. CONSTITUTION:When pulses P1-P4 shown by (A-1) are applied to a subordinate pixel A between subordinate pixels A and B having specific threshold value characteristics, black resetting is performed with the pulse Pi, writing is carried out with the pulses P2 and P3, and a gradational display with beta% transmissivity is maintained even after the pulse P4 is applied. Similarly, when pulses P1-P4 shown by (B-1) are applied to the subordinate pixel B, resetting into a black state is performed with the pulse P1, and a bright state is generated to some extent with the following P2 and P3 and not changed with the pulse P4, so that the bright state of some extent generated with the pulses P2 and P3 is maintained eventually. In this state, a white domain area of beta% only moves in parallel as compared with (A-1) and gradations of the same beta% with the subordinate pixel A are displayed.

Title: Method for forming quartz based porous glass body
Inventor: OKU MASATO
IPC: C03B20/00
Filed: 1992-08-04
Abstract: PURPOSE:To stably obtain a porous glass body having definite outer diameter and uniformed bulk density and free from residual foam by uniformly increasing density in a packed state of a formed material in a forming space. CONSTITUTION:When a porous glass body 26 is formed by compressing a forming material 25 in a forming space 22, oscillation energy is applied to the forming material 25 in the forming space 22 by an oscillation generating means (an oscillation generator 51) moving along an axial direction of a forming mold before compressing the forming material 25. Thereby, since the oscillation energy is applied to the forming material 25 in the forming space 22, packed state of the forming material 25 in the forming space 22 is made uniform in high density. Consequently, a porous glass body free from residual foam, having a definite outside diameter and uniform bulk density can stably be obtained.

Inventor: HAMANAKA KENICHI
IPC: G05B19/414
Filed: 1986-09-29
Abstract: PURPOSE:To avoid reduction of parameters and to ensure the effective control of parameters by storing various types of parameters into an IC card to prescribe the control contents of a machine. CONSTITUTION:A machine control operator of the maker side controls satisfactorily the action of a ram 13 of a press brake 5 and sets the prescribed value to a parameter.
