Abstract: PURPOSE:To obtain a recording medium having improved dispersibility and excellent electromagnetic conversion characteristic by dispersing primarily ferromagnetic metal or alloy powder in a vinyl chloride/vinyl acetate copolymer than adding a polyurethane resin thereto and dispersing secondarily the powder. CONSTITUTION:Ferromagnetic metallic iron or ferromagnetic alloy powder such as Fe-Co, Fe-Ni or the like is kneaded and dispersed together with an additive such as a dispersant, plasticizer, etc. into a copolymer consisting essentially of vinyl chloride/vinylacetate and contg. a slight amt. of maleic acid, vinyl alcohol, etc. if necessary, by which the powder is primarily dispersed. A polyurethane resin is then added to the magnetic powder and after the powder is secondarily dispersed, a curing agent is added and mixed to and with said powder, thereby preparing a magnetic paint. Such paint is coated on a substrate such as a plastic film or the like and is dried and cured while the magnetic powder is oriented, by which the recording medium having excellent surface smoothness and electromagnetic converting characteristic is obtd.

Title: Optical space transmission system
Inventor: YANO KENJIROU
IPC: H04B10/114
Filed: 1983-12-27
Abstract: PURPOSE:To attain 1:N optical space transmission among terminal devices of each room by installing a controller of the semi-duplex communication system and possible for reception of signal and distribution of reflected signal so as to constitute a network. CONSTITUTION:D1-Dn are placed in rooms #1-#3 and T1-Tn are the optical transmitters. The network NW is constituted by using the controller CTL for relay/distribution as the center. Transmission lines L1-L3 connect the CTL and optical transmitters O1-O3 at the NW side. This system is the semiduplex communication system and the optical transmitters O1-O3 are constituted to transmit signals at the same time as the reception. In this system, the data from the NW side optical transmitter O1 is stored once in the CTL and distributed at the same time to all the optical transmitters O1-O3. Since the O1-O3 receive a transmission enable signal RS, the transmitted transmission data SD is transmitted to each room at the same time by the optical signal. This is the same that the other optical transmitters O2, O3 receive the transmission data from the terminal device in the own room and becomes the transmission side. Thus, each terminal device can communicate with the terminal device of the own room and terminal devices in the other rooms.

Title: Display device and its driving method
Inventor: SHIRASAKI TOMOYUKI
IPC: H05B33/14
Filed: 1996-09-04
Abstract: PROBLEM TO BE SOLVED: To provide the display device which has good contrast in bright.dark conditions and is low in power consumption. SOLUTION: An organic EL light emitting element 12 is arranged at the back of a liquid crystal display section 13 as a back light and a reflection plate.

Title: Light-emitting element and circuit with the same built therein
Inventor: HOSOKAWA MAKOTO
IPC: H01L31/0352
Filed: 1999-09-06
Abstract: PROBLEM TO BE SOLVED: To quicken the response to injection of both the small and large quantities of light during reading, in photodiodes for writing. SOLUTION: Capacitance and resistance of a photodiode are reduced by using a laminated substrate, where a P-type epitaxial layer 142 is formed on a P-type semiconductor substrate 141, the layer 142 being doped more lightly than the layer 141. Thus, the response of the photodiode to small quantities of light during reading is improved. Furthermore, to prevent reduction of its response due to flattened potentials even if large quantities of light are incident during writing, the thickness of the layer 142 is reduced to limit the width of a depletion layer and increase electric field strength within the depletion layer. For example, the electric field strength within the depletion layer is set to 0.3 V/μm or larger, in view of the response to injection of large quantities of light required for a photodiode for writing (e.g. 6 times the writing speed). Furthermore, the required width of the depletion layer is set to 5 μm or larger for the response to injection of small quantities of light required of the photodiode for writing (e.g. 32 times the reading speed).

IPC: G02F1/1333
Filed: 1992-09-22
Abstract: PURPOSE:To reduce an electric field for driving a display device and hysteresis by incorporating a nonionic surfactant into a polymer dispesion type liq. crystal film. CONSTITUTION:In a display device using a polymer dispersion type liq. crystal film consisting of a water-soluble polymer matrix and liq. crystal particles dispersed in the matrix, a nonionic surfactant is incorporated into the liq. crystal film.
