Filed: 1990-10-30
Abstract: PURPOSE:To stably feed paper by a simple structure and simple assembling by providing a ribbon mask having a plurality of curved surface projections protruding toward a platen, the spring part elastically pressing the ribbon mask to the platen and the part engaged with a paper guide member formed thereto and a mask guide member formed by a smooth curve or a straight line to the periphery of an exposure window. CONSTITUTION:Printing paper is moved toward a platen 1 while both surfaces thereof are respectively guided by the surface of the first guide plate and a paper guide member 10 and pushed in toward the platen 1 as it is by its elasticity, that is, its stiffness. The leading end of the printing paper is introduced into the gap between the platen 1 and a ribbon mask 20 along the outer periphery 23a of a mask guide 23 without being hooked with the boundary part of the mask guide 23 and the ribbon mask 20 and elastically pressed to the platen 1 by the ribbon mask 20. When the platen 1 is rotated in a paper feed direction in this state, the leading end of the printing paper is moved toward the dot forming element exposing window 24 of the ribbon mask 20 to be levitated by projections 25 and, therefore, the leading end of printing paper is not hooked with the exposing window 24.

Title: Spread spectrum communication system
Inventor: UTA TAKAMOTO
IPC: H04B1/7075
Filed: 1996-11-07
Abstract: PROBLEM TO BE SOLVED: To provide the mobile communication system and the synchronization method for a spread code, in which a problem of a synchronization time of a long period code on an incoming channel is solved in a packet radio communication adopting the CDMA method. SOLUTION: Prior to transmission of an incoming transmission packet with a long period code, a mobile terminal equipment sends a short packet with a short period code on a reserved channel. A base station measures a propagation delay for each packet on a reserved channel through an initial synchronization circuit, taking tip synchronization timing and a packet separate circuit that separates packets which overlapped timewise. The measured propagation delay time information is used to set a coefficient in a proper timing to a matched filter for synchronization inverse spread, when a packet of a long period code sent from a transmission channel from the mobile terminal equipment is subjected to spread spectrum processing.  Thus, even when a large delay is provided to a transmission line in the spread spectrum packet communication, high-speed synchronization of a long period spread code is attained without much increase in the hardware scale.
