Title: Communication equipment and its method
Inventor: YOUNG EDDY KA PING
IPC: H04W8/04
Filed: 1997-09-09
Abstract: PROBLEM TO BE SOLVED: To much reduce signal traffic and to update a position more accurately by configuring the equipment such that the terminal equipment has a means to send a common position update signal and no different position update signal is sent to all users. SOLUTION: A common RF stage 304 is provided with a low noise amplifier(LNA) 344 that is connected to an input port of an antenna system 302 to amplify a signal received from a satellite and gives the amplified signal to an RF demodulator 340b. A processor 340 of the common RF stage 304 supplies position update signal data used to update positions of all registered subscribers via a user terminal equipment on a vehicle. Even when position updating is conducted comparatively frequently and accurately, since all signal traffic is comparatively low and only a single channel is required, the requirement of the common RF stage 304 is relaxed.

Filed: 1996-09-17
Abstract: PROBLEM TO BE SOLVED: To form an image without positional deviation by detecting the position of an image formed on a photoreceptor and controlling an optical system based on output from a detection means. SOLUTION: A reflector 24 in which a pair of reflection mirrors 24a and 24b are incorporated nearly at right angles is disposed in the optical path of a light beam from a scanning optical device to the photoreceptor drum 1.

Title: Pattern forming method for dyeable resin film
Inventor: HASHIMOTO MATSUO
IPC: B05D3/06
Filed: 1986-10-17
Abstract: PURPOSE:To reduce a processing period of the titled film by processing the dyeable photosensitive resin film with the aqueous solution containing A a non-ionic surfactant. CONSTITUTION:The film of the dyeable photosensitive resin composition composed of a copolymer comprising a dyeable photosensitive resin composition composed of a copolymer comprising a dyeable monomer, a hydrophilic monomer except said dyeable monomer, and a hydrophobic monomer as a constituting component, is mounted on the surface of a substrate such as a glass plate, and the obtd. film is exposed through a mask. At the time of processing the obtd. film with the developer, the aqueous solution of the nonionic surfactant is used for the developer. By incorporating the aqueous solution of the non-ionic surfactant to the developer, the processing period is reduced, and the resticking of the resin which exists in an unexposed part and is removed in the processing, is reduced, comparing with no addition of the surfactant to the developer. Thus, the rationalization of the processing step, and the improvements in quality and yield are attained. In this case, the non-ionic surfactant has the effects of promoting the wetting with water at the unexposed part, and an infiltration accelator,and the restocking of the removed resin is prevented, thereby enabling to processing for a short period.
