Title: Printing head for ink jet printer
Inventor: KOIDE YOSHIO
IPC: H04N1/23
Filed: 1989-03-31
Abstract: PURPOSE:To obtain a printing head favorable in droplet forming efficiency by disposing an organic piezoelectric film at a rear part of an ink chamber, and applying an AC voltage for droplet forming from an electrode. CONSTITUTION:An ink chamber 15 is provided in the interior of a nozzle 14, and an ink is supplied through an ink-supplying port 16. Since the ink contained in the ink chamber 15 is constantly pressurized, an organic piezoelectric film 12 is brought into close contact with an electrode 13 and the ink, and when a conductive ink is used, the front surface of the film 12 is grounded. Therefore, when an AC voltage for droplet forming is applied to the film 12, an ultrasonic vibration is generated, whereby the ink in the ink chamber 15 is vibrated, and an ink droplet is jetted out through the nozzle 14. Since the ultrasonic vibration is thus transmitted directly to the ink, a favorable dropletizing efficiency is obtained.

IPC: G01G23/48
Filed: 1987-03-30
Abstract: PURPOSE:To reduce the cost of an electronic balance by arranging a Zener diode with temperature characteristics approximating the temperature coefficient of the intensity of a magnetic field produced by a permanent magnet in the permanent magnet, and performing temperature compensation with the voltage value of the Zener diode. CONSTITUTION:A coil L is arranged in the magnetic circuit of the permanent magnet 1 and the Zener diode Zd having the same 250ppm/ deg.C temperature characteristics with the temperature coefficient of the magnet 1 is arranged in the hole of the magnet 1. A current I which flows through the coil L is converted by an output resistance R into a voltage, which is applied to a microcomputer from an A/D converter 5; and a current (i) is supplied to the diode Zd to generate a Zener voltage (v), which is supplied as a reference voltage to the converter 5. Then the diode Zd follows up the temperature of the magnet 1 and held at nearly the same temperature; even if the magnetic field varies owing to the temperature variation of the magnet 1, the compensation is performed at the time of the digital conversion of the current I flowing through the coil L and the current is inputted to the microcomputer. Thus, the inexpensive diode is used to reduce the cost.

Abstract: PURPOSE:To improve a hybrid IC board in characteristics, reliability, and yield by a method wherein a conductive layer is possessed of such a structure where two or more kinds of conductive layers are deposited. CONSTITUTION:An insulating layer 2 of Al2O3 or the like is formed on a conductive board base material 1 of Ti or the like, and a pattern of a deposited conductor layer 5 composed of a Cu layer 3 and an Al layer 4 is formed thereon. Usually, an insulating layer is deposited thereon, a via-hole is provided in the insulating layer concerned, and furthermore a conductive layer connected to the deposited conductive layer 5 is formed thereon. A bare chip, a resistor, a capacitor, and others are mounted on the board 1 concerned, which is hermetically sealed up with a resin mold or a metal package to form a hybrid IC. In this case, the deposited conductor layer 5 is composed of the Cu layer 3 and the Al layer 4. As Cu is higher than Al in electrical conductivity, the Al layer 4 can be lessened in thickness. Therefore, a hybrid IC board can be lessened in electrical resistance without increasing the deposited conductor layer 5 in thickness.
