Filed: 1989-07-24
Abstract: PURPOSE:To always obtain a constant pressing pressure of a pressure roller against paper to improve a paper slack preventing stability by a method wherein the pressure roller for pressing paper against a discharge roller feeding the paper at a speed higher than the feed speed of a tractor is mounted on a U-shaped plate fixed on a platen shaft. CONSTITUTION:When paper 5 is fed in a direction of an arrow (b), a tractor 18 is actuated and a platen gear 13 is rotated in a direction of an arrow (c). The rotation of the platen gear 13 causes a roller gear 16 to rotate in a direction of an arrow (d) through an idle gear 17 and results in the rotation of a discharge roller 14 coaxial with the roller gear 16. When passing through on the discharge roller 14, the paper 5 is pressed against the discharge roller 14 by a pressure roller 23 pressed in a direction of an arrow (a). The paper feed speed of the discharge roller 14 also set higher than that of the platen 11 or the tractor 18 allows the paper 5 payed out from the platen 11 to be always kept in a tensile state, thus preventing the slack of the paper 5.

Title: Repeater for transmission
Inventor: KATSUMATA YOSHINOBU
IPC: H04L5/16
Filed: 1990-07-19
Abstract: PURPOSE:To prevent an unnecessary data signal from being continuously outputted to a transmission line even at the time of input of a data signal longer than a set time by setting the transmission permission time of a transmission/reception part due to a self-transmission permitting means to a value shorter than the transmission stop time of the transmission/ reception part due to a transmission stop means. CONSTITUTION:The transmission permission time due to self-transmission permitting means 29 and 40 is set to a value shorter than the transmission stop time due to destination transmission stop means 49 and 50. When the transmission operation of a first transmission/reception part 23 is stopped after the set time of means 29 and 40 elapses after the start of the transmission operation of the transmission/reception part 23, the stop state of the transmission operation of the transmission/reception part on the destination side is continued by means 49 and 50. Consequently, a data signal is not fed back to a first transmission line 21 while this data signal is transmitted to a second transmission line. Thus, a part of the data signal. outputted to the transmission line 22 is not fed back to the transmission line 21 even if a signal unjustly longer than the set time set by means 29 and 40 comes to the transmission line 21.

Title: Molding method of foamed molding
Inventor: SHIBUYA TAKEHIRO
IPC: B29C44/10
Filed: 1984-09-14
Abstract: PURPOSE:To obtain a foamed molding consisting of an un-foamed outer shell with uniformly smooth surface and an expanded foamed core by a method wherein a mold cavity is applied with the pressure of gas having a pressure below the blowing pressure of expandable resin and the pressure of the gas is brought to communicate with the atmospheric pressure or below simultaneous with the completion of the injection and influx of the resin in the mold cavity. CONSTITUTION:Firstly, expandable resin in plasticizingly kneaded under the state that a pressure exceeding its blowing pressure is applied on the resin and measured and stored. Secondly, said measured and stored expandable resin is injectedly flowed in an enclosed mold cavity, which is pressurized with a pressure exceeding the smoothing pressure of the expandable resin by being supplied with gas, so as to form un-foamed outer shell successively onto the portion of the mold cavity, with which the expandable resin contacts simultaneously with its influx into the mold cavity. Simultaneous with the completion of the injection and influx of the expandable resin in the molding cavity, the injection of the expandable resin is stopped and the pressure applied on the resin in the mold cavity is lowered. At the same time, the supply of the gas to the mold cavity is stopped and the mold cavity is brought to communicate with the atmospheric pressure or below, resulting in expanding the expandable resin, which is in the mold cavity and covered with the un-foamed outer shell and, after that, expanding the expandable resin, which is covered with the un-foamed outer shell and expands in the core part, during the cooling process. After being cooled and solidified, a molded body is removed from the mold cavity. Thus, the foam molded body with excellent dimensional stability is obtained.

Title: Feeding device of paper
Inventor: KITAZAWA CHIHIRO
IPC: B41J15/16
Filed: 1983-10-13
Abstract: PURPOSE:To enable to feed rolled paper exactly in a prescribed quantity at high speed, by providing a paper feeding lever which engages with a cam fixed to a continuously-rotating shaft, and a rolled-paper feeding lever which engages with rolled paper, and by letting out the rolled paper more than one pitch of the paper feeding after the completion thereof. CONSTITUTION:A rolled-paper feeding lever 11 is stopped at a first position 32 when it is on standby. With the rotation of a paper feeding lever 5, the lever 11 is rotated in the direction reverse to an arrow 30 by a spring 25. When a paper feeding pawl 7 rotates a ratchet 17 to the end, the lever 11 is rotated to a second position 33. Then a spring member 11a pushes rolled paper in the direction of the arrow and rotates a roll 23, and thereby the lever 11 is put in the state of standby. By this operation, the rolled paper is let out somewhat more than one pitch of the paper feeding. A time required for the rolled-paper feeding lever 11 to be rotated from the position 32 to the position 33 is shorter than a time required for the paper feeding pawl 7 to rotate the ratchet 17. Therefore the rolled paper 23 is released temporarily from a tensile force, and thus the paper feeding can be performed by a very small power.
