摘要:
This specification discloses a method of toner transfer development in which a low frequency alternating electrical bias is applied to the space between a latent image bearing member and a developer carrying member to develop the latent image on the latent image bearing member, and an apparatus for carrying out the same method. This bias has a first process in which reciprocal movement of developer particles is effected also between the non-image area of the latent image bearing member and the developer carrying member, and a second process in which the intensity of the bias is adjusted so that one-sided movement of developer particles from the developer carrying member to the image ara and one-sided movement of developer particles from the non-image area to the developer carrying member may take place.

摘要:
Orientation of a liquid crystal is controlled by first forming a phase boundary of the liquid crystal between a monoaxially anisotropic phase where the liquid crystal molecules are aligned in one direction and a higher temperature phase between a pair of base plates, transforming a part of the higher temperature phase adjacent to the phase boundary under cooling into the monoaxially anisotropic phase where liquid crystal molecules are aligned in parallel with the liquid crystal molecules in the already formed monoaxially anisotropic phase, and successively causing the phase transformation in the direction perpendicular to the phase boundary.
摘要:
A liquid crystal device comprising a ferroelectric liquid crystal placed under bistability condition with two stable states. The ferroelectric liquid crystal is placed under the bistability condition in the presence of a surface which has been uniaxially orientation-treated. The molecules of the ferroelectric liquid crystal align so as to be twisted in the thickness direction of the liquid crystal layer in either of the two stable states. The average dipole moments of the liquid crystal molecules in the two stable states are in mutually opposite polarities.
摘要:
A liquid crystal showing a cholesteric phase at a higher temperature than the temperature giving a smectic phase is interposed between a pair of base plates to give a liquid crystal device. At least one of the base plates has a face to which an orientation controlling function is imparted for preferentially orienting the liquid crystal molecules in contact with the face in one direction.
