Title: Ink jet head
Inventor: HIRAGA KAZUYA
IPC: B41J2/14
Filed: 1988-05-17
Abstract: PURPOSE:To make an ink jet head compact by forming a nozzle with a piezoelectric element material. CONSTITUTION:A holder containing a nozzle 1 and a streamlining valve element 2 and an auxiliary ink tank 3 are closely attached to each other, and the auxiliary tank 3 contains a filter in the direction of the nozzle. In addition, the auxiliary ink tank is connected to an ink tank through a tube 4. The nozzle 1 which is a piezoelectric element contracts due to an applied voltage, and the backflow of ink from the rectifying valve element 2 to an area in the direction of the auxiliary ink tank is prevented by the valve element 2. Therefore, the ink 7 can be ejected from the nozzle 1 using a pressure generated by the nozzle 1. Furthermore, when the nozzle 1 returns to its original shape, the valve of the valve element 2 opens, resulting in the supply of the ink in the direction of the nozzle 1. Thus the length of the ink jet head can be shortened.

Abstract: PURPOSE:To obtain an inexpensive heat-resistant and electrically conductive resin composition, having high heat resistance, simultaneously excellent in strength, processability and dimensional stability and suitable as IC trays. CONSTITUTION:A heat-resistant and electrically conductive resin composition is obtained by using an inexpensive nylon 66 resin as a synthetic resin which is a substrate and blending mica powder in an amount of 5-40wt.% based on the total weight content for improving its heat resistance and simultaneously adding carbon black in an amount of 5-30wt.% based on the total weight content for imparting electric conductivity. Since the mica powder has a fear of incurring deterioration in processability and physical properties, mica powder having the surface treated with a silane coupling agent is used to improve the strength and dimensional stability of molded products. Furthermore, a low-molecular weight polyester-based liquid crystal resin in an amount of 0.5-10wt.% based on the total weight content is added to prevent the processability from deteriorating.
