Title: Driving method for liquid crystal display device
Inventor: TAKADA ASAO
IPC: G02F1/133
Filed: 1988-12-26
Abstract: PURPOSE:To drive a liquid crystal display element irrespective of a variance of a threshold voltage of a two-terminal element by absorbing the variance of the threshold voltage of the two-terminal element and applying a prescribed voltage to the liquid crystal element. CONSTITUTION:When CL00 - CL0m = CL and CD00 - CD0m denote the capacity of a liquid crystal element and the capacity being parallel to a two-terminal element, respectively, in general, they are CL CD. When a signal electrode X0 is driven by a high impedance signal Ic0=Ic, a charge QL charged to a liquid crystal element CL02 during a scanning period (t) becomes QL=(IcXt) CL/(CL+(m-1)CD), in CL CD. Accordingly, a voltage variation DELTAVL of the liquid crystal during this time becomes DELTAVL=(IcXt)/(CL+(m-1)CD), and it comes not to have relation with a threshold voltage Vdth of the two-terminal element. In such a way, at the time of bringing a liquid crystal to active driving by a two-terminal non-linear element, the liquid crystal element can be driven to a prescribed voltage irrespective of a variance of the threshold voltage of the two-terminal element.

Filed: 1988-12-27
Abstract: PURPOSE:To evade a delayed alarm and a non-fire alarm by setting operation accumulation time which becomes reference to judge fire based on the inclination of a sensor level at the point of time when the sensor level exceeds a prescribed level. CONSTITUTION:A physical quantity based on a fire phenomenon detected by a fire phenomenon detecting means FS is stored in a storage area RAM 1 as the sensor level SLV at every prescribed time interval. The sensor level read in at every prescribed time interval to find the inclination of the sensor level for a time is stored in time series in the sensor level storage area RAM 1, and the oldest sensor level is erased at every reading of a new sensor level and every storage of the sensor level in the storage area RAM 1. And the rising tendency of the sensor level i.e. the inclination is found, and the operation accumulation time to discriminate the fire from the inclination is decided. In such a way, detecting time can be accelerated when the likelihood of the fire is high, and also, the non-fire alarm when the sensor level rises steeply can be evaded.

IPC: G03G15/02
Filed: 1997-11-28
Abstract: PROBLEM TO BE SOLVED: To suppress sinking in an electrifying member and electrification noise by combining a specified foamed elastic layer and a resistor layer. SOLUTION: This electrifying member is a roller type comprising a conductive core metal 1a and a foamed elastic layer 1b, a resistor layer 1c and a surface layer 1d formed around the core metal. The conductivity of the foamed elastic layer 1b is controlled by properly adding a dielectric agent such as carbon black and conductive metal oxide into an elastic material such as rubber, and the elasticity or hardness of the layer is controlled by adding a softening oil or plasticizer or by foaming. The resistor material which constitutes the resistor layer 1c is preliminarily formed into a film of a seamless tube shape and then fitted to form the resistor layer of the electrifying member 1.  Since the resistor layer 1c is in contact with the foamed elastic layer 1b, a material having oil resistance with little changes in its characteristics against the softening oil or plasticizer in the foamed elastic layer 1b is selected for the resistor layer. Further, as for the material of the surface layer 1d, a resin containing an ethylene-butylene copolymer is used.
