Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To reduce the cost of the whole device and simplify the piping configuration by generating the required control pressure by a single control valve. SOLUTION: When a solenoid 72 of a control valve 64 is excited, both rods 93, 94 are moved to the right, so that a second valve seat 77 is subjected to seating of a second valve element 87 to close an air valve 88. After that, as the second valve seat 77, a piston 6 and a first valve element 75 are moved in a body to the right, a negative pressure valve 84 is opened. Thus, the communication between the air chamber 68 and the variable pressure chamber 67 is interrupted, and on the other hand, negative pressure is introduced into the variable pressure chamber 67, too through a negative pressure passage 85, and the negative pressure in the variable pressure chamber 67 is supplied to an actuator not shown. At this time, the atmospheric pressure is applied to the right side of the second valve seat 77 to energize the second valve seat 77 to be pushed back to the left.  Accordingly, it is possible to generate control pressure proportional to the intensity of an electric current applied to the solenoid 72.

IPC: B65H1/26
Filed: 1987-04-27
Abstract: PURPOSE:To aim at simplification of the structure of a paper feeding cassette together with improvement of the form supply capability by providing a spring which energizes a paper feeding cassette in the direction of a paper feeding roller. CONSTITUTION:A paper feeding cassette 2 is being pushed up by the elastic force of a spring 9 when it is not loaded with forms. If a bottom plate 5 is loaded with a fixed quantity of forms under such situation, the spring 9 is pushed down by the weight thereof so as to complete the supply of forms to a paper feeding cassette 2. Subsequently, the paper feeding cassette 2 is installed in the storage section of the copying machine proper 1. Hereupon, since the bottom plate 5 is energized by the elastic force of the spring 9 in the direction of a paper feeding roller 7, the forms are fed by the rotation of the paper feeding roller 7. Since the total weight of the paper feeding cassette 2 and the forms decreases as the forms decreases in quantity by degrees, the paper feeding cassette 2 is pushed up by the elastic force of the spring 9, so that the forms are forced to come in contact with the paper feeding roller 7 by the aid of a guiding device.

Title: Ink jet printer and method for controlling pump thereof
Inventor: HANAOKA YUKIHIRO
IPC: B41J2/175
Filed: 1998-04-15
Abstract: PROBLEM TO BE SOLVED: To prevent abnormal ink ejection by reducing pressure being generated from a pump stepwise after a specified pressure level is reached and discharging ink from an ink jet head. SOLUTION: When a bubble enters into an ink channel, a control means commands operation of a pump unit to turn a pulse motor steadily for a specified time thus beginning rotation of the pump rotator 104 in the direction of arrow (a). During that stroke, a roller 105 turns while collapsing a tube 103 from region X to Y and reduces the inner pressure of the tube 103 below the atmospheric pressure thus sucking ink from the nozzle 11A of an ink jet head 11 through a cap 17 connected with the tube 103. When the pressure in the cap 17 is saturated, rotational speed of the pulse motor is decelerated and the pressure in the cap 17 is reduce stepwise to a level slightly lower than that corresponding to steady rotation of the pulse motor thus discharging ink from the ink jet head 11.
