Title: Organic electroluminescent element, its manufacturing method, and display device
Inventor: CHIBA YASUHIRO
IPC: H05B33/12
Filed: 1999-09-20
Abstract: PROBLEM TO BE SOLVED: To provide a top light taking type organic electroluminescent element reducing generation of leakage currents and having high reliability by reducing sputtering power during the initial period of deposition when forming a transparent conductive film on an upper cathode through sputtering, and by raising the power thereafter so that deposition by sputtering is made possible within a processing time such that the element can withstand production, for reducing damage to an organic layer on a bed. SOLUTION: The organic layer 10 of this organic electroluminescent element includes a luminescent layer which emits light through the recombination of holes supplied from an anode A with electrons supplied from a cathode K. To manufacture it, an anode formation process for forming the anode A on a substrate 1, an organic-layer formation process for forming the organic layer 10 on the anode A, a cathode formation process for forming on the organic layer 10 the cathode K in a thickness that enables light to pass therethrough, and a transparent conductive deposition process for depositing a transparent conductive film 12 by sputtering to cover the cathode K are effected. In the transparent conductive deposition process, the electric power required for sputtering is set at a low value during the initial period of film formation and is set to become higher as the deposition progresses.

Title: Dither circuit
Inventor: TANAKA YOSHIKAZU
IPC: H03M1/04
Filed: 1991-10-15
Abstract: PURPOSE:To prevent the deterioration in the S/N of an input signal of a very small level by detecting the zero level of an input signal and selecting the level of a dither generating circuit so as to be increased and applying dither to the input signal. CONSTITUTION:When the level of an inputted digital signal is not zero, the dither signal of a prescribed level is fed to the input signal from a dither generating circuit 4 by an adder 5. When the level of the input signal is zero, a digital zero detection circuit 2 detects it and gives its output to a dither level changeover circuit 3, which increases the level generated from the dither generating circuit 4 more than that when the level of the digital input signal is not zero, the increased dither level is added to the input signal by the adder 5 and a signal processing circuit 6 processes the signal and the result is outputted from a digital output terminal 7. Thus, when the level of the input signal is small, the S/N is not deteriorated and when the level of the digital input signal is zero, the limit cycle is prevented.

Title: Speed controller of wound-rotor induction motor
Inventor: AZUMA KAZUHIKO
IPC: H02P21/04
Filed: 1985-11-25
Abstract: PURPOSE:To reduce maintenance cost and to extend the life of the brush and a cleaning period by using a brush near the optimum current density that minimizes its wearing amount. CONSTITUTION:When an induction motor 1 is rotated a a high speed, the secondary current of the motor is supplied through brushes 3X, 3Y to power converters X, Y. When the motor 1 operates at low speed, a relay unit 20 receives an OFF control signal from a controller 19 to open a contact 20a. Thus, the brushes of energized state are only brush 3X group so that the number of brushes is reduced by half as compared with at high speed operation, but since the secondary current of the motor passing the brushes 3X group is approx. half of that at rated time, the brush current density becomes equivalent optimum value to that at rated time. The wearing amount of the brushes 3Y group through which a current does not flow consists of only mechanical wear, which is smaller compared with that at current flowing time.

Title: Neutral titania sol and production thereof
Inventor: SAKAMOTO MASASHI
IPC: C01G23/00
Filed: 1986-11-10
Abstract: PURPOSE:To obtain homogeneously dispersed neutral titania sol in a stable state, by mixing acidic titania sol with a water-soluble high polymer compound and adding an alkaline solution to the resultant sol. CONSTITUTION:Titanium hydroxide is initially subjected to peptization treatment with a monobasic acid or salt thereof to form acidic titania sol. The titanium hydroxide is obtained by, e.g. hydrolyzing a titanium sulfate solution while heating. The titanium hydroxide is normally neutralized with an alkaline substance, e.g. aqueous ammonia, filtered, washed and dehydrated to remove sulfate radicals left in the interior as much as possible and a monobasic acid, e.g. hydrochloric acid, nitric acid, acetic acid, chloric acid, or chloroacetic acid, is added to the dehydrated substance to carry out peptization treatment. Titania sol formed by the peptization treatment contains the monobasic acid as a stabilizer and exhibits acidity of pH 1-3. The above-mentioned acidic titania sol is then mixed with a water-soluble high polymer compound solution and an alkali solution is added to neutralize the acidic sol to afford the aimed neutral titania sol.

Title: Non-shifting type swinging plasma torch
Inventor: HOSHINO TADASHI
IPC: H05H1/34
Filed: 1997-09-30
Abstract: PROBLEM TO BE SOLVED: To swing high temperature gas flames without diffusing or cooling the flames by forming an aperture of which a part is enters into the inner space of a nozzle stand and which is aligned with the center axial line of an electrode in one end face, forming an aperture made eccentric from the center axial line of the electrode in end face in the outside of an inner hollow, and installing a plasma nozzle communicating both apertures. SOLUTION: Plasma arc is generated between the tip end of an electrode 20 and the inner surface of the plasma nozzle 52 of a nozzle member 50, ionizes plasma gas which passes through a nozzle 52, and blows out of an outer aperture 51. Plasma flames are jetted out at a certain angle to the center axis 21 since the outer aperture 51 is made eccentric to the center axis 21. When an electric motor 70 is driven, the nozzle member 50 is rotated and driven and consequently, the outer aperture 51 is moved while drawing a circle on the center axis 21 and the plasma flames jetted out of the outer aperture 51 move as to draw conical face on the center axis 21. As a result, processing is carried out with uniform heat distribution in a wide range by one scanning within a range of plasma flame radiation.

Title: Semiconductor memory
Inventor: OHATA KENICHI
IPC: G11C11/41
Filed: 1998-09-04
Abstract: PROBLEM TO BE SOLVED: To provide a high speed SRAM(static random access memory) whose cycle time is reduced. SOLUTION: A bit line recovery circuit BR has both the functions of a bit line load and of a circuit recovering a bit line. A diode DL0 and a PMOS transistor MR0 are connected in series to each other between a power supply VCC and a bit line B0. A diode DL1 and a PMOS transistor MR1 are connected in series to each other between the power supply VCC and a bit line B1. MEQ denotes an equalizing transistor. The VCC potential is given to a control signal CBR simultaneously when a writing signal WD0 (or WD1) is applied. In a reading cycle, as a load is composed of the PMOS transistor and the diode, even if the equivalent resistance of the PMOS transistor is reduced to the extent that a bit line can be pulled up at a sufficiently high speed, the necessary amplitude of a signal between bit lines for the sensing amplifier can be secured.  For the pull-up in a writing cycle, the equivalent resistance of the diode is very much reduced and the equivalent resistance at the time of bit line recovery is equal to the equivalent resistance of the PMOS transistor and a recovery time can be sufficiently reduced.

Abstract: PURPOSE:To improve the ability of a computer system by transferring directly the data on a move-in buffer to an instruction processor of a requester when this data is requested by another instruction processor. CONSTITUTION:A deciding means 20 decides whether the data requested by the instruction processors 12-1 -12-N for transfer to a main storage 10 are held in a buffer 16 or not. If so, the data are read out of the buffer 16 and transferred to the requester processors 12-1 - 12-N by a transfer means 22 provided in each instruction processor. Therefore the data stored in the buffer 16 are transferred to the processors 12-1 - 12-N with no intervention of a cache memory 18 when these data are requested by these processors. Thus the processing ability of a computer system is improved.
