Title: Manufacture of liquid crystal display element
Inventor: ISHII MASAMI
IPC: G09F9/30
Filed: 1986-03-14
Abstract: PURPOSE:To prevent a metallic film pattern from becoming thin, disconnecting and disappearing by adhering a metallic film on only a part nearby the periphery of a substrate, etching the metallic film selectively except a desired part, and forming a metallic film electrode pattern. CONSTITUTION:The metallic film is vapor-deposited locally a little bit larger than the metallic film pattern 5 and the metallic film pattern occupies only the narrow part at the peripheral part of the substrate, so the etching of other parts of the locally vapor-deposited film is completed almost simultaneously with the end of the etching of the electrode pattern of the metallic film, and the desired metallic film electrode pattern does not become thin, have a disconnection, and disappear. Further, even if there is an insufficiently etched part and a step on a substrate surface which can be viewed with the naked eye and do not cause a short circuit at the boundary between the part which is etched for the removal of the metallic film and the part which is not etched because of the presence of the metallic film, the position is closer to the periphery of the substrate than the boundary line between the effective display part and ineffective display part, so the user of a liquid crystal display device can not see it and there is offensive sight.

Title: Magnetic bubble stretcher
Inventor: SUZUKI MAKOTO
IPC: G11C11/14
Filed: 1983-04-01
Abstract: PURPOSE:To provide sufficiently wide bias magnetic field margin by changing the length in one transfer path pattern group when a magnetic bubble moves from one transfer path pattern group to the next transfer path pattern group to eliminate an error attended with the stretching of the magnetic bubble. CONSTITUTION:The length of the magnetic bubble is l1 at the lower end of an (a) column transfer path but the length is stretched to the length of l2 while being transferred to the upper half of the (a) column transfer path. Since the transmission and receiving of the magnetic bubble from the (a) column transfer path to the (b) transfer path are attained while keeping the length of l2, no conventional problem occurs. Further, while the upper half of the (b) column transfer path is transferred, the magnetic bubble is stretched again. Thus, the magnetic bubble is stretched to a desired length. That is, when the magnetic bubble crosses a gap between the transfer paths of a stretcher, its length is unchanged, a magnetic bubble driving force equal to any part of the magnetic bubble stretched long is operated to suppress malfunction of the magnetic bubble transfer of the stretcher.

Title: Interconnector for solid electrolyte fuel cell
Inventor: IPPONMATSU MASAMICHI
IPC: H01M8/02
Filed: 1993-03-16
Abstract: PURPOSE:To let no phase transition take place at any temperature, and thereby chemically stabilize the cell by making each grain small in size by making use of the grain size effect of oxide in a LaCrO3 series. CONSTITUTION:When the crystal grain size of oxide in a LaCrO3 series is made small in a level of submirons, a crystal system is changed so as to be formed into a stable cubic system. There is no phase transition in the cubic system, thereby phase transition will never take place at any temperature. In order to form an interconnector composed of oxide in a LaCrO3 series, the crystal grain size of which is small enough as mentioned above, a thin film is formed over a porous electrode substrate, in this case, if alkali earth metal employed for doping is Mg, a product excellent in chemical stability can thereby be obtained. Moreover, if the composition of oxide in a LaCrO3 series is an A site defect type, a product which is more excellent in chemical stability, can thereby be obtained. Since the aforesaid crystal, in a cubic system has no phase transition point, thereby phase transition will never take place at any temperature, and the aforesaid crystal is chemically stable, so that it can withstand repeated operations for a long time.

Title: Sheet conveyance change-over device
Inventor: TAJIMA AKIO
IPC: B65H29/60
Filed: 1989-03-08
Abstract: PURPOSE:To enhance the effecting printing speed of a printer by providing a solenoid having an actuating shaft which is extended by a first spring upon deenergization and is retracted upon energization, and a second spring which gives a flap an urging force by which the flap follows a displacement of the actuating shaft. CONSTITUTION:When a recording sheet 1 is discharged into a stacker 3a after being led into a conveying path 2a, a solenoid 11 is deenergized while a solenoid 12 is energized. Accordingly, an actuating shaft 12a is retracted overcoming the resilient force of a first spring 2b, and a clockwise rotational moment is given to a flap by the resilient force of a second spring 6b. This rotational moment is set at a value which does not hinder the conveyance of the recording sheet 1. When the trailing end part of the recording sheet is passed the flap 6, the flap swings 6 so as to open a branch path to a conveying path 2b so as to introduce a next recording sheet into a stacker 3b. Accordingly, the change-over of the flap can be made without waiting for the completion of passing of the recording sheet, thereby it is possible to enhance the effective printing speed of the printer.

Title: Color plasma display
Inventor: KOYAMA MASATAKA
IPC: H01J11/24
Filed: 1998-02-21
Abstract: PROBLEM TO BE SOLVED: To provide a color plasma display which emits a high brightness, has a long lifetime, and consumes less power. SOLUTION: When an AC drive voltage is applied between electrodes 56 and 60, a line of electric force E is formed, while a line of magnetic force M is generated from a vertically magnetized film 52. Because these lines E and M intersect perpendicularly in a space in which a gas is encapsulated, charged particles in the plasma generated by discharging move in the direction of the line E while they wind round the line M. The lifetime of the charged particles becomes longer than in the case free of magnetic field. Accordingly time charged particles collide with non-electrolytically dissociated gas molecules more than in the case free of magnetic field to cause the gas molecules to make electrolytic dissociation. Therefore, the density of the plasma is heightened to an extreme degree, and the voltage to start the electrolytic dissociation will lower.

Filed: 1995-03-15
Abstract: PURPOSE: To provide an apparatus for driving a rotor of an open-end spinning machine, having high reliability and capable of accurately and mechanically synchronizing the speeds of an outer rotor and an inner rotor without performing troublesome control. CONSTITUTION: This apparatus for driving a rotor of an open-end spinning machine comprises a differential gear unit 50 used in order to synchronously rotate an outer rotor 13A with an inner rotor 13B. The rotation on the side of the outer rotor influenced by a change in tension of a tangential belt 18 and that of a driving system of a yarn takeout roller or a yarn winding roller both without being influenced thereby are inputted to the differential gear unit 50. Both the rotations are synthesized in the differential gear unit 50 to output the rotation corresponding to the fluctuation in rotation on the side of an outer shaft to an inner shaft 13b.  Thereby, the inner rotor is rotated at a suitable rotational frequency corresponding to a fluctuation in the tension of the tangential belt even if the tension is changed and the fluctuation is caused in the rotational frequency of the outer shaft 13b.
