IPC: C03C25/24
Filed: 1988-08-11
Abstract: PURPOSE:To obtain a secondary coating layer which maintains a high modulus of elasticity, increases the resistance to external stresses and has an excellent bending characteristic by coating the outer periphery of the coated optical fiber consisting of an optical fiber and a primary coating layer with a thermoplastic resin exhibiting a smectic liquid crystal property by melt extrusion coating as a secondary coating. CONSTITUTION:The coating material having the excellent bending characteristic is obtd. while the high modulus of elasticity is maintained by coating the outer periphery of the optical fiber consisting of the optical fiber and the primary coating layer with the thermoplastic resin exhibiting the smectic liquid crystalline property by melt extrusion coating as the secondary coating. The smectic liquid crystalline thermoplastic resin can be synthesized by a polymn. method such as melt polycondensation method or acid chloride method. The intrinsic viscosity of the smectic liquid crystalline thermoplastic resin is preferably at least 0.1dl/g. Although this resin can be applied by the melt extrusion method on the optical fiber, the molding in the temp. range to form the smectic phase is more preferable in order to utilize the specific orientation thereof.

Title: Driving method for ink jet head
Inventor: TAKADA NOBORU
IPC: B41J2/055
Filed: 1986-08-25
Abstract: PURPOSE:To reduce the size of ink droplets jetted and enable clear recording in a high density, by applying a driving waveform with a period of an integer times a period 1/(2fR2), wherein fR2 is the frequency of vibration of the normal mode of an ink jet head, to a piezoelectric element of the ink jet head. CONSTITUTION:When an ink jet head is loaded with an ink and the frequency of a sinusoidal driving waveform applied to a piezoelectric element is gradually raised, the displacement quantity of a nozzle meniscus has peaks at frequencies fR1 and fR2, which are the frequencies of vibration of the normal modes of the ink jet head. When a driving waveform with a period of 1/(2fR2) (namely, n=2) is applied to the piezoelectric element of the ink jet head, the liquid surface of an ink is brought into vibration corresponding to a resonant state of a high order mode. In this experiment, the inside diameter of the nozzle is 50mum and the diameter of an ink droplet jetted is about 20mum. Accordingly, the ink droplet is reduced to about 1/3 in diameter and to about 1/27 in volume, as compared with an ink droplet obtained by a conventional system.

Title: Semiconductor package
Inventor: KAMATA CHIYOSHI
IPC: H01L23/00
Filed: 1988-08-12
Abstract: PURPOSE:To prevent heat dissipating effect from decreasing and a short-circuit accident on a mounting face from occurring by so providing a space part as not to allow solder to adhere to inside a shape line for forming an index or on the line when a package is dipped in a solder bath to coat external leads with solder. CONSTITUTION:A space part is provided inside a shape line for forming an index 3 or on the line. When a ceramic package is dipped in a solder bath to coat the external leads 5 of the package with solder, the adherence of the solder to the index 3 is suppressed. For example, the area of a metallized part is minimized, to hollow-out the interior of the circular or square index 3. Accordingly, the solder does not adhere to the hollowed interior thereby minimizes the solder adhering amount, the protrusion of the solder is avoided, and a conductive foreign matter can be avoided. Thus, it can prevent heat dissipation from decreasing and short-circuit accident on a mounting face from occurring.
