Title: Liquid crystal display
Inventor: MASAKI YUICHI
IPC: G02F1/139
Filed: 1983-04-13
Abstract: A liquid crystal display device utilizing the guest-host mode has liquid crystal material containing added dichroic dye between a pair of substrates (5, 6) carrying electrodes (7, 8), with homogeneous alignment layers on one region (9) producing homogeneous or twisted alignment, and homeotripic alignment layers on another region (10). Alternatively the homogeneous or twisted region may be replaced by a hybrid alignment region, with a homogeneous layer on one face opposed to a homeotropic layer on the other. Positive colour display with the advantageous positive dielectric anisotropic liquid crystal material is then practical. The cell may have reflective layer (6) and polarizer (P). <IMAGE>

Title: Sealing element
Inventor: LATTY CYRIL XAVIER
IPC: F16J15/12
Filed: 1983-06-06
Abstract: A sealing element is provided, which sealing element is more particularly intended for the joining of tubes of small diameter of a circuit of fluid at high temperature. It comprises an annular metal core 12 in which is formed at least one circular recess or groove 14 for receiving a lining 16 of expanded graphite which, before compression of the sealing element, projects from each side of the metal.

IPC: F02P9/00
Filed: 1986-05-01
Abstract: A conductive collar 8 is crimped around one end of the high voltage cable between the coil and distributor of the ignition system and conductive collars 10 are crimped around each high voltage cable connected to a spark plug. The leakage current inductively picked up by each collar is fed via a respective circuit 17 including a diode 20 and a capacitor 21 to a circuit 19 including a diode 22 and a capacitor 23. The collected leakage current charges the capacitor 23 which is connected to a collar 12 crimped around the other end of the high voltage cable between the coil and distributor cap so that the discharge of the capacitor 23 returns the leaked energy to the ignition system. Coils 18 are positioned adjacent wires 7, 9 of the circuit 13 to recover energy which would otherwise be lost by corona discharge. The entire circuit 13 is encapsulated in a body of plastics and is mounted on the high voltage cable between the coil and distributor. <IMAGE>
