Title: Portable terminal device
Inventor: ADACHI TADASHI
IPC: H04W56/00
Filed: 1996-07-15
Abstract: PROBLEM TO BE SOLVED: To enable an originating call and an incoming call by resetting a mode and immediately establishing synchronization with a control channel, for instance, at the time of entering an area of a base station in the case of a mode where receiving interval of a control channel is long. SOLUTION: When a microcomputer of a PHS is out of synchronization with a control channel, the microcomputer becomes a receiving state of the control channel only for a time W2 at intervals of a time t1 (six seconds) (ST23 to ST29). When synchronization with the control channel is not established within a time T, the microcomputer is switched to a state where it receives the control channel only for the time W2 at intervals of time t2 (thirty seconds), the so-called a battery saving mode (ST30 to ST37). When a speech communication key is operated in the saving mode, the saving mode is reset and the microcomputer is switched to a state which receives control channels (ST40 to ST44). When synchronization with the control channel is not established within a time t3, the microcomputer moves to the saving mode.  When synchronization with the control channel is established, positional register processing is performed, and then the microcomputer is switched to a waiting state (ST38 and ST39).

Filed: 1996-07-15
Abstract: PROBLEM TO BE SOLVED: To obtain an optical coupler which is easily producible and is not subjected to the influence of reflected return light by eccentrically forming the high-refractive index part of a rod lens connected to the front end of an optical fiber for transmission from its central axis, thereby forming the optical coupler. SOLUTION: The rod lens 1A has nearly the same outside diameter (d) as the outside diameter of a single mode type optical fiber 2 and is constituted in such a manner that the central axis 14 of a columnar body provided with its end face 1a perpendicularly an axial direction and the center 13 of the high-refractive index part are parted. Dopants, the such as germanium, to increase the refractive index are so added to the rod lens as to be more at the center 13 of the high-refractive index part and to be gradually fewer toward the outer peripheral direction by which the rod lens is formed.  According to such constitution, the high-refractive index part of the rod lens 1A connected to the front end of the optical fiber 2 for transmission is formed to be eccentrically formed from the central axis 14 and therefore, the light advances toward the high-refractive index part when the light passes the rod lens. Then, the reflected return light generated at the end face of the rod lens 1A is released toward the outer side of the optical fiber 2 for transmission without passing the same route.
