Abstract: PURPOSE:To obtain a liquid jet recording head capable of obtaining a high response frequency by a method wherein a magnetic fluid is mixed in a liquid, and a means which generates a stationary and constant intensity magnetic field from a flow path toward a discharge opening is provided in the liquid near a thermal operating part. CONSTITUTION:A recording head is composed of a discharge opening 10 and a flow path 12 equipped with a thermal operating part 11. The inside of said fluid path 12 is filled with liquid via a supply opening 13 and a liquid chamber 14. An electromagnetic coil 17 is buried in a flow path part of a roof plate 16, i.e., a part opposed to the thermal operation part 11, and a heat energy operation area of the thermal operation part 11. The liquid receiving the heat energy generates a state change accompanying a steep increase in volume, is discharged from a discharge opening 10 by an acting force, is stuck to a material to be recorded, and recording is performed. When a current is made to flow to the electromagnetic coil 17 in that case, a magnetic field is generated in the arrow A direction. Since a tensile force in the same direction is generated in the liquid, the reset of a meniscus is performed by a sum of surface tension of the liquid itself and force received from the magnetic field, and the quick reset of the meniscus can be performed. Then, a high response frequency as a head characteristic can be obtained.

Title: Driving method for solenoid valve
Inventor: SHIMAMURA MORIHIKO
IPC: F16K31/06
Filed: 1987-12-03
Abstract: PURPOSE:To relax striking noise of a plunger, when it is attracted, by changing duty ratio of excitation voltage in a solenoid valve so as to be decreased during a period of the plunger from its attraction start time to attraction completion time.
