Patent JP-S621185-A (JP)
Title: Semiconductor integrated circuit device
Inventor: YANAGISAWA KAZUMASA
IPC: H03K19/00
Filed: 1985-06-26
Abstract: PURPOSE:To prevent a DC current from flowing between both MOSFETs by connecting serially an N-channel output MOSFET to a P-channel output MOSEFT so as to obtain an output voltage at a common source point and level-shifting a common voltage division voltage by means of a MOSFET of the same conductive type diode mode so as to supply said voltage to the gates of both output MOSFETs. CONSTITUTION:The P-channel MOSFET Q54 of a diode mode and the N-channel MOSFET Q55 are serially connected between a voltage division point Vcc/2 and the grounding potential Vss of a circuit. The gate and drain of the MOSFETs Q53 and Q54, both of which are made in common, are supplied to the gates of output MOSFETs Q56 and Q57. The threshold voltages of the MOSFETs Q53 and Q54 are set smaller than those of the corresponding MOSFETs Q56 and Q57. Thus DC current will not flow through both MOSFETs Q56 and Q57.

Title: Ink jet head
Inventor: NAGASAKA FUMIO
IPC: B41J2/045
Filed: 1990-05-28
Abstract: PURPOSE:To make an ink jet head adaptable to the use of a wax ink by a method wherein a magnetic passage enclosed with a magnetic body outside an ink chamber and a highly magnetic body of a diaphragm is formed and the temperature of an exothermic body on the diaphragm is so controlled as to change the magnetic permeability of the highly magnetic body, a member of the diaphragm, to excite the diaphragm into vibrations. CONSTITUTION:A permanent magnet is provided at a horizontal part 11 and a magnetic passage is formed by being enclosed with the Ni alloy part of a highly magnetic plate 8 and a diaphragm 9. Ink discharge is effected by energizing an electrode 18 to activate an exothermic body 17 to generate heat. Concerning the magnetic body of the diaphragm 9, its Curie temperature reaches near 150 deg.C due to the component ratio of the materials constituting a magnetic passage part 15 mounted by electrolytic process. When the exothermic body is energized, therefore, the magnetic permeability of the part heated by the exothermic body is reduced considerably, resulting the failure to retain the conventional balance of the magnetic suction force. For this reason, the magnetic suction force acts mainly upon the end part of the magnetic passage part 15 of the diaphragm having a still high magnetic permeability. At this time, the balance position is changed to produce about 6mum displacement near the center of the diaphragm 9.

IPC: H01J61/72
Filed: 1989-05-31
Abstract: PURPOSE:To reduce tube wall blackening by constituting an inner lead wire and an auxiliary anode connecting to this inner lead wire of nickel under a specific amount respectively of a carbon content and an oxygen content. CONSTITUTION:When a nickel wire containing carbon is strongly shocked by ions and electrons, carbon and nickel carbide sputter, and when these are stuck, a blackened film is produced. When the nickel wire containing free oxygen and a metal oxide is shocked by ions and electrons, free oxygen and steam and emitted, when these combine with mercury, mercury oxide is produced, and when this is stuck, the blackened film is produced. Consequently, an inner lead wire and an auxiliary electrode connected to the inner lead wire are constituted of nickel having a carbon content less than 0.05wt.% while having an oxygen content less than 0.10wt.%. Thereby, even when strong ion shock is given, there is no danger of tube wall blackening.
