Title: Information transmission method and device between transmitter and receiver
Inventor: BOCCALETTI STEFANO
IPC: H04L27/00
Filed: 1998-03-30
Abstract: PROBLEM TO BE SOLVED: To transmit protected data by transmitting a signal, i.e., a difference function, between two corresponding variables of the 1st and 2nd dynamic systems via a transmitter, interrupting the signal to be sent to the transmitter for a period longer than the mutual relation time set between the dynamic systems of the transmitter and receiver via the receiver, and expanding the dynamic system of the receiver separately from the 2nd dynamic system of the transmitter. SOLUTION: A transmitter 1 consists of two identical chaos dynamic systems and is represented in a nonlinear function. The message to be sent to a receiver 3 from the transmitter 1 is coded into a variable x1 (t). The systems x2 , and x3 must be synchronous with each other for transmission and therefore the receiver 3 sends a variable y3 (t) that is turned into a variable y2 , by the functions x2 and z2 to the transmitter 1. The synchronization is surely performed based on a fact that both Lyapunov exponents x2 and z2 are negative.

Filed: 1990-03-30
Abstract: PURPOSE:To obtain this high sensitive body while improving the wear resistance by providing plural photoconductive body layers laminated on a supporting body and making a transmissivity of the uppermost photoconductive layer >=90%. CONSTITUTION:The conductive supporting body whose surface is mirror finished 1 is formed of an Al alloy stock pipe. Then, the surface 1 is immersed into a solution dispersing 3wt. pts. of gamma type nonmetallic phtalocyanine as an electric charge generator in a vehicle and by pulling up the substrate 1, the electric charge generating layer 3 with 0.2-1.0mum of a film thickness is formed on the substrate 1. Next the charge generating layer 3 formed on the surface of the supporting body 1 is dried. After drying the charge generating layer 3, a solution obtained by dissolving 10.5 wt.pts. of a butadiene series compound and 4.5wt. pts. of hydrazone series compound is used to form an electric charge carrier layer 5 with 10-30mum of film thickness by an dip coating method. For example, as shown on a curved line (a), when the carrier layer is set at 99.9% (>= 90%) the voltage is dropped quickly and the sensitivity is improved.

Filed: 1983-05-18
Abstract: PURPOSE:To bring a toner scooping sheet into contact with the surface of a photosensitive body and to prevent toner from spilling by attaching the scooping sheet to a cleaning device in such a way that the sheet is tensed. CONSTITUTION:The scooping sheet 5 is formed of urethane rubber, fluororubber, silicone rubber, or flexible material with proper elasticity. The sheet 5 with length l0 is drawn to l(=l0+a) and stuck to a support member 6 in the drawn state. Thus, a toner guide member S is constituted and arranged facing the upstream-side device of a cleaning blade. Consequently, the sheet 5 is flexible and properly elastic, so the sheet even when about 500mum thickness neither damages the surface of a photosensitive body nor deforms in a corrugated shape. Even if the sheet 5 is caused by an environmental change to deform, its corrugation is prevented by determining the material, the extent of drawing, and instantaneous stress in consideration of the change previously.

Since the distance db and the spacing wb are fixed, the position where the information is to be displayed, i.e., the distance da from the diffusion screen 5 to the display information, is changed by changing the distance Wa within a range smaller than the distance Wb. The distance Wa of this time is set by adjusting the light modulation by an optical modulator 2 within the range smaller than the distance Wb according to the scanning speed by a scanning system in the positions 13, 14 where laser beams are made incident on the diffusion screen. As a result, the information is displayed and observed at an arbitrary distance from the diffusion screen 5.
