Title: Light emitting display device
Inventor: YAMANAKA YASUHIKO
IPC: G09F9/00
Filed: 2001-02-23
Abstract: PROBLEM TO BE SOLVED: To provide a bright light emitting display device enhanced in the availability of light of the device by suppressing the lowering of contrast ratio caused by external light without using a polarizing plate. SOLUTION: The light reflected on a reflecting film 2 reaches a light exiting surface at an angle of total reflection or larger by making a tilt angle γ to the total reflection angle or larger to the light exiting surface 5 of the reflecting film 2, therefore, the light is totally reflected on the light exiting surface 5, and the external light can be confined in the light emitting display device. Emission of the light emitting means 2 is made to exit from the light exiting surface 5 and goes into the eyes of an observer of the light emitting display device. Thus, it is possible to achieve favorable display without using a polarizing plate by suppressing decrease in a contrast ratio due to the external light.

IPC: H04J13/00
Filed: 2001-03-14
Abstract: PROBLEM TO BE SOLVED: To provide a method for operating a cellular mobile radiotelephone network characterized by including a step to perform a request to service from a mobile set, and a step to demodulate the burst of a message and then to passe the demodulated data to a radiotelephone network controller(RNC). SOLUTION: When the mobile set performs a handover within a cellular system, first, the mobile set searches a best cell to which it can be connected, next tries to transmit a message to the found best cell. In a CDMA cellular system, a likelihood to be received successfully by a cell having the random access channel(RACH) message of the mobile set is largely dependent on sending power. The cellular mobile radiotelephone network is disclosed. As a characteristic, the mobile set requests service by a format related to a first cell in which the mobile set is located by using data modulated on one common RACH. A base station in a cell adjacent to the first cell is composed so that the burst of the RACH message having the format related to the first cell is demodulated and the demodulated data are passed to the RNC. Thereby, mean power required for successfully transmitting the RACH message can be reduced.
