Patent JP-H0252835-A (JP)
Title: Sheet feeding device
Inventor: MIYAJIMA TAKASHI
IPC: B41J15/04
Filed: 1988-08-17
Abstract: PURPOSE:To enable the stable feed, freed from unevenness in feed, of sheets and to reduce the generation of a constant curl by a method wherein a roll paper containing part is movable to a feed roller by means of a resilient member, and a paper is guided by means of the outer periphery of an idler roller located between a roll paper in the containing part and the roller to feed it to the roller. CONSTITUTION:During the feed of a sheet, a feed roller 15 is driven with the aid of a feed motor 16, and a roller 15 is rotated in a direction A to deliver a sheet 11a. Simultaneously, rotation is transmitted to an idler roller 14 and a roll paper 11, which are rotated in directions B and C, respectively. The sheet 11a is unreeled from the roll paper 11, and is fed to the roller 15 after it passes the lower half periphery of the roller 14. In which case, since the roll paper 11 is rotated through the roller 14, high back tension is not applied on the sheet 11a, and there is no need to exert a high conveyance force on the sheet by means of the roller 15. Thus, the press force of a head spring 20 does not need a high force required for conveyance, and may be a force required only for recording. The curl of the sheet 11a is straightened during the passage of the sheet around the outer periphery of the roller 14.

Title: System for transmitting charging signal of radio communication system
Inventor: OBA YOSHIYASU
IPC: H04W88/02
Filed: 1987-08-20
Abstract: PURPOSE:To execute a charging action without fail by transmitting a pilot signal from a base station, transmitting a resending requesting signal from a mobile station corresponding to the receiving turn-off of the signal, and repeating the transmission of an alternating current signal in a fixed time from the transmission start of the alternating current signal in the base station to receive the signal. CONSTITUTION:In accordance with the deterioration of a receiving condition, when a pilot receiving signal fPLdm goes to an L, the output of an inverter IN 39 turns to an H, and an output (r) goes to the H. For this reason, a resending requesting signal fPp, which uses different frequecies from those of an alternating current signal fak, is transmitted through an antenna 31. Thus, the said fPp is given to a receiver SR 118 after recovering the deterioration of a transmitting/receiving condition, an output (l) of the SR 118 turns to an L, and the output of an IN 119 goes to the H. A TM 114 is started again, and the re-transmission of the alternating current signal fak is executed. Consequently, since the re-transmitted alternating current signal fak is sent out as a regular charging signal KPq, the charging action is executed at a TEL p2 at this time without fail.
