Title: Ink jet recorder and method for cleaning recording head used for the recorder
Inventor: TAJIKA HIROSHI
IPC: B41J2/16
Filed: 1991-01-19
Abstract: PURPOSE:To reduce troubles, such as dust or others fed back into delivery ports caused by wiping and ink led out from the delivery port, by a method wherein when a delivery port forming surface of an ink jet recording head is cleaned by wiping, a wiping direction is determined in accordance with the shape of the delivery port. CONSTITUTION:With respect to a delivery port which is not linearly symmetrical to an axis orthogonal to a wiping direction, the longest one of segments formed by cutting the predetermined axes along the profile of the delivery port is compared with two peripheral length components of the delivery port on the both side of the segment. The delivery port is wiped from the shorter component to the longer one. For example, when a delivery port 101b is shaped into a trapezoid having an upper edge and a lower edge in a direction parallel to the predetermined axes, the shorter component is the lower edge and the longer component is the sum of the upper edge and two inclined edges. By specifying the wiping direction in accordance with the above delivery port shape, the trouble can be reduced.

IPC: B60K17/10
Filed: 1979-01-22
Abstract: PURPOSE: To prevent a motor from excess load operations caused by the variation of the load in a working system by changing the discharge pressure of an auxiliary pump according to the displacement of a pulley and the slant angle of a swash plate in the above-said pump for controlling the set input torque of a variable capacity pump in a driving device for running.  
     CONSTITUTION: A variable capacity oil pump 7 is driven by a motor 1, and an oil pressure motor 8 is driven by the discharged oil therefrom for running a combine. Meanwhile, an output shaft 3 is driven through a belt 5 for operating various work devices 6. At this stage, when the load to the work device 6 is increased to increase the tension of the belt 5 and a pulley 12 is displaced by Δ against a spring 11, the displacement is detected by a displacement detecting device 13. A signal corresponding to the displaced position is sent to a regulator 14, and the slant angle of a swash plate in a variable capacity pump 7 is regulated by an amount equivalent to the displacement for controlling the discharge. Thus, the motor 1 is prevented from excess loads, and controlled in the optimum speed for running.
