Title: Optical writing device
Inventor: ISHIWATARI TAHEI
IPC: G03G15/04
Filed: 1989-04-06
Abstract: PURPOSE:To stably and analogously vary the intensity of an irradiation light to a photosensitive body by constituting at least a part of an optical path extending from a light source to the photosensitive body, of an optical fiber, and varying the transmission light quantity by applying pressure to its optical fiber. CONSTITUTION:When an optical fiber is deformed by applying pressure thereto, a total reflection condition in an interface of a core and a clad gives way, therefore, a loss of a light beam which transmits through the optical fiber is generated. Since the variation quantity caused by this loss of the light beam corresponds to magnitude of applied pressure, the transmission light quantity from the optical fiber can be varied analogously. Accordingly, by constituting at least a part of an optical path extending from a light source 1 to a photosensitive body 5, of the optical fiber 2, and applying pressure to the optical fiber 2 by a pressure applying element 3, the intensity of an irradiation light to the photosensitive body 5 can be varied stably and analogously.

IPC: B62D11/18
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To provide a crawler vehicle having a steering controller limiting self-permanent turns.

Title: Method and device for inter-frequency hand-off in radio communication system
Inventor: KUO WEN-YI
IPC: H04B7/12
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To improve an inter-frequency hand-off quality by minimizing repetitions of the inter-frequency hand-off between an existing connection frequency and a new connection frequency. SOLUTION: Communication units 103 and 104 of a multi-carrier CDMA system 100 perform transmitting and receiving operations via different frequency bands corresponding to different carriers. Radio signals corresponding to the different carriers are combined together by a combiner in the forward direction before these signals are transmitted from an antenna. In the opposite direction, signals received at the antenna are turned into signals corresponding to the different carriers through a filter. The same traffic channel is used for this connection as long as the communication units 103 to 105 are kept in the same cell in response to each call.  When the units 103 to 105 move to another cell, an hand-off operation is carried out via the same or different frequency bands between a base station under the service that is controlled by a relevant communication unit and a base station of the new cell.
