Title: Production of ferroelectric liquid crystal element
Inventor: MATSUNAGA MASAAKI
IPC: G02F1/1337
Filed: 1989-02-28
Abstract: PURPOSE:To improve the uniform orientability of the liquid crystal element by injecting a liquid crystal from the reverse grain direction of an oblique orientation layer. CONSTITUTION:The liquid crystal is injected from the reverse grain direction of the oblique orientation layer. For example, the liquid crystal display cell is constituted of transparent electrodes 13 of 1,000Angstrom , two sheets of upper and lower glass substrates 11, 12 stuck with SiO column-like microstructures 14 of 800Angstrom  and an epoxy resin seal 15 and a spacing of 2.5mu is maintained. The ferroelectric liquid crystal 'CS-1014(R)' produced by CHISSO is injected from the direction 16 which is of the inverse grain with respect to the SiO column-like microstructures 14, by which the liquid crystal display element is formed. The liquid crystal molecules are made to arrive at the root of the SiO column in this way and since the orientation is thereby regulated, the good orientation is obtd.

Filed: 1988-02-29
Abstract: PURPOSE:To enable a satisfactory reproducing tone to be heard by providing a second head targeted to perform cancellation on one side, performing the phase inversion of the recording current of a first head, and mixing a signal in which crosstalk jumps in with the signal reproduced by the first head. CONSTITUTION:The signal supplied to an inversion amplifier 12 is phase- inverted, and is set at an appropriate level at a second recording amplifier 11, and is supplied to a head 19, and is converted electromagnetically. At this time, an induction noise 15 jumps in a head 18. The signal obtained by the head 18 is amplified at a second reproducing amplifier 10, and is supplied to a cancellation amplifier 5.
