Title: Roller processing method for raising flange and device therefor
Inventor: SAWA MASUMI
IPC: B21D19/04
Filed: 1993-01-18
Abstract: PURPOSE:To efficiently perform a flange raising process that is stable in quality by holding the flange part of a workpiece between a pair of rollers, moving the axial center of both rollers while holding the flange part therebetween to bend the flange part, and moving both rollers along the flange part while keeping a holding state. CONSTITUTION:A starting point for bending is formed by holding the flange part WE between both rollers 6, 7 and moving a roller pressing part 3 in the raising direction; and by operating a robot hand 2 in this state and moving the roller pressing part 3 along the flange part WE, a flange raising process is performed continuously. Consequently, only by fixing the workpiece W at a prescribed position, dispersion in processing accuracy is eliminated, and a large number of workpiece W are efficiently processed for flange raising. In addition, since the moving locus of both rollers 6, 7 are obtained by controlling the robot hand 2, it is easy to deal with the change of shape for the workpiece W.

Filed: 1985-02-12
Abstract: PURPOSE:To handle a liquid crystal panel as a strong substrate by forming a spacer provided in an insulation area by using the same material as peripheral sealing materials at the same time. CONSTITUTION:After forming a sealing section 6 and a spacer section 14 of a stripelike 'adductor' made of polyimide resin, another semihard transparent substrate is installed while facing the face on which electrodes 21, 23 and an orientation film 3' are formed in vacuum in the upper side. Then, the outside is pressurized and the inside is made to vacuum, and uniform pressure is applied from the outside. At the same time, it is heated, and the spacer and sealing materials are brought into close contact with other faces by a press cure system. As respective substrates 11' are in close contact substantially with each other, the space between electrodes becomes definite even if its vacuum state is released, and difficulties such as a part of the panel is too wide etc. do not take place. Further, the display panel itself has strength substantially equal to strength of two pieces instead of strength of one piece only.

Filed: 1982-02-18
Abstract: PURPOSE:To improve the receiving performance of a narrow-band signal and a spread spectrum signal sent at the same frequency and under the time division, by enlarging the level difference between the two detecting times and narrowing the band. CONSTITUTION:A narrow-band signal impressed upon an input terminal 1 passes through a band pass filter 3a and only the thermal noise component of the signal is subjected to a band limitation. On the other hand, a signal subjected to a spread spectrum at an inverse spread modulator 4 is limited in band at a band pass filter 3b. Furthermore, the spread spectrum signal impressed upon the input terminal 1 is limited in band at the band pass filter 3a. The spread spectrum signal inputted into the inverse modulator 4 is changed into a narrow-band signal by the inverse spread after its code synchronism is established at a code synchronism tracing section 5 and passes through the filter 3b under the same condition. The level difference occurring between input signals (c) and (d) of detectors 7a and 7b is compared at a comparator 8 and both receiving signals are received under the most suitable condition by changing over a switch 9 in accordance with the condition.
