Title: Driving device of web take-up frame
Inventor: TAJIMA FUJIO
IPC: G11B15/46
Filed: 1980-08-15
Abstract: PURPOSE:To attenuate the transient vibration which is caused by the intermittent driving, by detecting the shift of the web behavior to the reference state and then calculating and delivering the energizing signal that controls a take-up motor so as to attenuate only the specific frequency component. CONSTITUTION:A web 1 is taken up to a take-up frame 3 from a supply frame 4 through an information exchange station 2 like a magnetic head, etc. The behavior of the web 1 such as the speed, acceleration, tension, etc. is detected by sensors 9 and 10. Then the shift of the web behavior to the reference state is calculated by an adder 11, and this output is turned into the energizing signal that controls a take-up motor 5 to give the attenuation to the specific frequency component on the frame 3. The energizing signal is weighted at an operator 12 and applied to a motor driver 7. A position feedback signal 8a which is applied to a control circuit 6 from  a speed position detector 8 is used for an input of the adder 11 via a coefficient  device to save the number of sensors 9 and 10.

Title: Flux coating method and coating device for soldering
Inventor: SAWADA AKIRA
IPC: B23K3/00
Filed: 1978-09-12
Abstract: PURPOSE: To enable even flux coating to be performed over the entire part of substrate by coating the foamed flux to the substrate with a rotary brush.  
     CONSTITUTION: A motor 10 begins to run a fixed time before a substrate 8 passes a flux coating device for soldering. A brush fixing shaft 5 is then revolved by a gear mechanism to cause a brush 6 and receiving frame 4 to revolve. Where the brush 6 faces the substrate 8 side, the motor 10 stops running. On the other hand, at the same instant when the motor 10 starts running, the air supplied from an air supply source passes through a pipe 2 and is supplied to a foaming element 3 which in turn causes the liquid form flux in a flux liquid tank 1 to foam. The foamed flux advances in the state of having returned to liquid form flux to the end of the brush 6 owing to capillarity of the brush 6, whereby the liquid flux is coated on the substrate 8.

     CONSTITUTION: An amino resin precondensate obtained by the heat-condensation of a mixture of 1mol of an amino compound such as urea, melamine, etc. and 1.5W 12mol of an aqueous solution of e.g. formaldehyde, is added with 0.3W3mol of a ketone compound such as acetone, methyl ethyl ketone, etc., and condensed by heating at 50W100°C under alkaline conditions (pH8W12). The co-condensation is continued under acidic condition (pH3W6) to obtain milky ketone-modified amino resin emulsion. The objective emulsion is obtained by mixing 100pts.wt. of the amino resin emulsion obtained above with 5W100pts.wt. of an aqueous rubber latex. The storage stability can be improved by adjusting the pH of the emulsified resin liquid to 5W8, and cooling the liquid. The same adhesivity can be attained either by mixing the rubber latex in advance, or by mixing just before use.

Title: Paper feed device of printer
Inventor: SATO MITSUTOSHI
IPC: B41J13/036
Filed: 1986-05-19
Abstract: PURPOSE:To prevent the generation of the shift of a printing operation or the jamming of paper at the time of the reciprocating operation of paper, by uniformizing the pressure contact force of a platen roller and a paper feed roller by applying load allowing the rollers to be ready to bend by providing back-up rollers behind said rollers. CONSTITUTION:Because back-up rollers 15a, 15b are fixed in a rotatable manner, constant pressure is applied between the back-up rollers 15a, 15b, rollers 3a, 3b and a platen roller 2 in the direction shown by an arrow Y by the back-up rollers 15a, 15b to contact all of rollers under pressure. Therefore, the rollers 3a, 3b are uniformly contacted with the platen roller 2 under pressure over the entire lengths thereof and, as a result, the pressure applied to paper 4 becomes uniform over the entire width thereof. This relation is kept regardless of the rotary direction of the platen roller 2. Therefore, by setting the energizing force of a spring 13 sufficiently large, the effect of the tension of the paper 4 or a transfer sheet 5 is reduced and the shift of the printing position at the time of the reciprocating operation of the paper 4 is prevented.

Title: Transfer paper guide device of electrophotographic copying machine
Inventor: KURIMOTO AKIRA
IPC: G03G15/14
Filed: 1982-07-01
Abstract: PURPOSE:To smoothly guide transfer paper even if the paper thickness varies, and to enhance image quality of a copy, by fixing one end of an elastic member for guiding the paper to one of upper and lower guide plates, and bringing the other end into contact with the forward end of the other guide plate. CONSTITUTION:One end of an elastic member 4 for guiding the transfer paper is fixed to the upper guide plate 2 and the other end is held in contact with the forward end of the lower guide plate 3. The transfer paper P travels forward in the arrow direction while releasing the contact between the member 4 and the plate 3. The end of the paper P is guided along the end of the plate 3 by the pressing force of the member 4, and arrives at the prescribed transfer point of a photoreceptor 1 without colliding against it. Since the forward end of the paper P is corrected in the direction, and contacts with the photoreceptor 1, stains on the reverse side of the paper and deficiency of transfer are prevented even if thickness of the paper P varies.
