Title: Linear reciprocating motion device
Inventor: WATANABE JIYUNICHI
IPC: F16H19/02
Filed: 1981-02-20
Abstract: PURPOSE:To reduce the fluctuations of a wire inclination angle and a path length to prevent abnormal sound generation by allowing a turn pulley which transmits the rotary force of a driving pulley to a travelling member by means of a wire, to slide longitudinally along a support shaft. CONSTITUTION:When a driving pulley 14 rotates, one end part of a wire 18 is wound in and the other end part of the wire 18 is delivered out to cause the wire 18 to be shifted so that a travelling member 10 is subjected to linear reciprocating motion along guide shafts 11, 13. A wound position of the wire 18 changes in the longitudinal direction of the driving pulley 14 following the rotation of said pulley 14, and accompanied with this change turn pulleys 16, 17 move along support shafts 16a, 17a in the changing direction of the rolled position of the wire 18 at the driving pulley 14 from the wire 18. Consequently, even if the rolled position of the wire of the driving pulley changes, the abnormal sound is not produced since little changes in the inclination angle and the path length of the wire is obtained.

Title: Ink jet recorder
Inventor: MORIGUCHI HARUHIKO
IPC: B41J2/185
Filed: 1991-01-25
Abstract: PURPOSE:To eliminate the wasteful use of ink caused by a recovery action by a method wherein the temperature or the like of an electrothermal energy conversion body is detected for every delivery port or port group driven by the electrothermal energy conversion body, and when a difference from a predictive value is more than a set value, a recovery processing is applied only to the appropriate delivery port or port group. CONSTITUTION:An electrothermal energy conversion body 22 provided for every delivery port 29 of a recording head generates heat by an electric conduction, thereby heating ink in a liquid path 26 to deliver a predetermined amount of ink drops from the delivery port 29. When a clogging causes non-delivery or unsatisfactory deliver of ink, heat accumulated in the appropriate delivery port 29 increases and results in a temp. of the electrothermal energy conversion body 22 higher than a normal temp.. Therefore, the temp. or resistivity of the electrothermal energy conversion body 22 or the temp. thereabouts is detected and compared with a predictive value. If the difference is more than a set value, a recovery processing, such as an ink suction by a suction pump, is applied only to the appropriate delivery port 22 or a group including the delivery port 29.
