Title: Liquid crystal optical element and its production
Inventor: HATTORI SHUJI
IPC: G02F1/1333
Filed: 1995-01-17
Abstract: PURPOSE: To produce a liquid crystal optical element with low driving voltage and little hysteresis even when the element is used for a display by constituting the capsule wall from a polymer material having urethane bonds in the molecule. CONSTITUTION: In this liquid crystal optical element, a liquid crystal/polymer composite film comprising encapsulated liquid crystal particles dispersed in a particulate state and a matrix material which includes these particles, the wall material of the capsule consists of a polymer material having urethane bonds in the molecule. The polymer material having urethane bonds in the molecule is prepared from urethane oligomers and has a low mol.wt. and good solubility with a liquid crystal or comonomers. The polymer is an extremely flexible material although it has no soft segment. These characteristics contribute to reducing the driving voltage of the element which is produced by using this polymer material. Moreover, since the polymer synthesized from urethane oligomers has proper crosslinks, it does not increase the hysteresis of the element produced by using the polymer.

Filed: 1982-02-16
Abstract: PURPOSE:To enable to perform a safe automatic stopping and starting, by a method wherein an engine is brought to a stop by setting a parking brake during operation of an engine, and it is brought to a start by pressing a release button when a parking brake is engaged during a stop. CONSTITUTION:If a parking brake is set during operation of an engine, a signal S1 is brought to ''H'', an FF circuit 9 is set by means of a signal S6 of an one shot-MV1, and a fuel cut signal S15 is brought to ''H'' to stop an engine. This causes the number of revolutions S5 to be below a given value VS, and brings a signal S9 into ''H''. Then, if a release button is pressed during stopping of the engine in order to disengage a parking brake by which a signal S1 is broutht to ''H'', a signal S3 is brought to ''H'', the FF circuit 9 is reset by means of a signal S8 through an one shot MV3, the fuel cut sinal S15 is brought to ''L'' to set an FF circuit 10, an AND circuit 8 is formed by means of the signal S8 and signals S1 and S9, and a starting motor driving signal S14 is brought to ''H'' to start the engine. Thus, the engine does not start even if the release button is pressed under a condition that a parking rake is not set, and this this eliminates the possibility of reckless running.
