Title: Electrochromic display element
Inventor: YAMANAKA TORU
IPC: C09K9/02
Filed: 1988-02-12
Abstract: PURPOSE:To prevent degradation of a display characteristic by repetitive driving by using rare earth metal triphthalocyanines as a display layer. CONSTITUTION:A rare earth metal triphthalocyanine film 3 is formed by a spin coating method, vacuum deposition method, etc., on a display electrode 2 provided on a substrate 1 to form the display layer. This substrate and a substrate 1 provided with a counter electrode 5 are disposed to face each other via a spacer and a liquid electrolyte 4 is sealed therein. The rare earth metal triphthalocyanine is further higher in molecular weight than the conventional electrochromic material and has less change in film structure with age such as flocculation and crystallization; further, the substantially amorphous display layer is formable in the case of the rare earth metal triphthalocyanine film having a substituent of >=4C. The degradation in the electrochromic characteristic is thereby obviated even after repetitive use.

Title: Constitution method of radio zone for mobile communication
Inventor: SAKAMOTO MASAYUKI
IPC: H04W16/02
Filed: 1984-02-24
Abstract: PURPOSE:To improve the efficiency for repetitive use of frequency by irradiating >=2 radio zones by a fan-shaped directional antenna within a horizontal plane among those radio zones which use radio channels of the same frequency and setting the antenna directivity in the direction opposite to a specific radio zone. CONSTITUTION:A fan-shaped antenna 14 is set in the direction opposite to the traffic center part in order to decrease the number of desired channels. The effect is improved as the traffic taper is increased between radio zones as it is understood clearly from the allocating procedure of channels. In other words, if a positive difference is obtained between the total number of desired channels of zones #8-#19 and that of zones #2-#7, the sum of the number of channels equivalent to 1/3 said difference value and the channels within a repetition unit of the center part is equal to the number of desired channels of this system. The 1/3 said difference value is decided since the repetitive use is possible three times within zones #8-#19.
