Abstract: PURPOSE: To record a color image on a normal sheet with high quality by using ink having a surface tension of the critical surface tension or less of a recording medium, giving thermal energy to an ink liquid passage to generate bubbles in the ink of the passage, and discharging the ink. CONSTITUTION: When a current (a pulse signal) instantaneously flows to a heating element 21 to abruptly heat ink 23 near the heater 21 in the state that a liquid channel 20 is filled with the ink 23 having low surface tension of the critical surface tension or less of recording medium, bubble nuclei are generated by film boiling in the ink 23 on the element 21, and integrally abruptly started to expand. The bubbles continuously expand to grown mainly toward a discharge port 24 side having small inertial resistance, and finally to exceed the port 24. Then, the bubble internal pressure of negative pressure flows into the bubbles so that the ink 23 is pressed to the port 24 to flow forward and to be transferred to a recording medium as independent liquid droplets.

CONSTITUTION:An ordinary steel sheet is used for two external sheets 10, 10 and the one side external sheet 10a is stuck to the undersurface of partition walls 12 comprised of an expanded metal prepared of the same steel sheet with an adhesive agent. Then cast iron powder 16 to 100 meshes is filled into cells 14... surrounded by the external sheet 10 and partition walls 12.... Then the other side external sheet 10b is stuck to the top of the partition walls 12... and the cells 14... are closed up tightly. With this construction, a vibration of the external sheet is checked at a contacting surface between the external sheet and the powdery body, consumed as frictional energy and a vibration damping effect is displayed. Since the vibration spread to the powdery body is consumed within the powdery body, the vibration damping effect becomes remarkable further. There is no dependence on a temperature at all further and the vibration damping effect is not deteriorated even under a high temperature.

Title: Relaxation oscillation circuit
Inventor: MIYAKE TOSHIHIDE
IPC: H03K3/0231
Filed: 1988-12-27
Abstract: PURPOSE:To attain high speed operation with simple constitution by executing non-saturation operation. CONSTITUTION:At the time of oscillating operation, to a minimum collector voltage Vcc-400mV of a first transistor Q1, the maximum voltage of an emitter is Vcc-200mV-VBE and the minimum value of VCE is VBE-200mV. Samely, concerning a second transistor Q2, the minimum voltage of the collector is Vcc-400 mV and the maximum voltage of the emitter is Vcc-200mV-VBE. In such a way, since any transistor is operated with non-saturation, the high speed operation is executed. The VBE is a voltage between the base and emitter of the transistor and the VCE is the voltage between the collector and emitter of the transistor. Thus, without using a current mirror circuit or level shift transistor, etc., the high speed operation can be executed by a simple circuit.
