Inventor: KISHIMOTO TOSHIKI
IPC: C30B9/12
Filed: 1989-07-28
Abstract: PURPOSE:To easily and inexpensively obtain a titanium potassium arsenate single crystal by adding a specific compd. as a flux at a prescribed ratio to KTiOAsO4 and maintaining the m. p. within a range where arsenic acid does not evaporate thereby executing a flux method. CONSTITUTION:The compd. expressed by K2ZO4 (Z is W, S, Mo, Cr) is added as a flux to titanium potassium arsenate. The amt. of the addition is confined in the range where the ratio of titanium potassium arsenate attains 15 to 50mol% of the entire part. The mixture is then put into a crucible and is heated to melt uniformly; thereafter, the mixture is slowly cooled. The resulted product is charged together with the crucible into water and the dissolved and deposited titanium potassium arsenate single crystal is recovered. The titanium potassium arsenate single crystal is easily produced under atm. pressure in this way and the resulted single crystal has the characteristic to convert an IR YAG laser beam to green light with high conversion efficiency.

Title: Dielectric filter
Inventor: KAWAKAMI IZUMI
IPC: H01P5/08
Filed: 1986-08-20
Abstract: PURPOSE:To improve the transmission loss between output terminals and to miniaturize a dielectric filter by giving a coaxial terminal structure provided with a center conductor and an outer conductor, which is connected to an earth pattern and covers the center conductor with an insulator between them, to at least one of input and output terminals of a substrate. CONSTITUTION:When a microwave is supplied to an input terminal 3, it is transmitted to an output terminal 4 by electromagnetic fields successively generated in respective dielectric resonators 10b adjacent to one another in a filter body 10. If the input terminal has not the coaxial terminal structure, the transmission loss is reduced by propagation of the electromagnetic wave according as a length L between input and output terminals is shorter as shown by a curve A. The coaxial structure is given to an input terminal 3 and its outer conductor 3c is connected to an earth pattern 2. Thus, propagation of the electromagnetic wave in a substrate 1 between input and output terminals 3 and 4 is cut off and the transmission loss is improved as shown by a curve B in comparison with the conventional curve A. Therefore, a required transmission loss is secured even if the length L between both terminals 3 and 4 is shortened, and the dielectric filter is miniaturized.

Title: Driving circuit for switching transistor
Inventor: ISHII TAKUYA
IPC: H02M3/335
Filed: 1985-09-04
Abstract: PURPOSE:To actuate a switching transistor at a small loss and at a high speed by utilizing the corrector current as the base current of an NPN transistor flowing only during the carrier storage time when a switching transistor is turned off. CONSTITUTION:When the output of an oscillation circuit 21 becomes low, an NPN transistor 22 turns off and no base current is supplied to a switching transistor 29 while the corrector current keeps flowing only during the carrier storage time of the switching transistor 29. During this time the current induced to a current transformer 30 is charged into a condenser 25 through a diode 27. By this charged current the voltage is produced at the both ends of a resistance 26 and the base of an NPN transistor 23 is made a positive bias turning it ON. Thus with such a simplified constitution, the switching transistor can be turned off efficiently and at a high speed.

Abstract: PROBLEM TO BE SOLVED: To melt the solidified metal stuck to a porous plug and to recover a gas permeability in a short time by immersing a lance near the porous plug having tendency to clogging, blowing gas and stirring molten steel in a ladle. SOLUTION: When the porous plug 3 in the ladle 1 has tendency to clogging, the lance 4 is immersed near the porous plug 3 in the molten steel 2 from an immersion tube 5.

IPC: G09F9/30
Filed: 1999-07-09
Abstract: PROBLEM TO BE SOLVED: To make it possible to form fine barriers for separating the pixel regions disposed on transparent conductive films by electrodeposition coating with an inexpensive device. SOLUTION: The transparent conductive films 3 are formed like stripes in the prescribed direction on a glass substrate 2 and are provided thereon with the barriers 4 apart prescribed spacings. Organic electric field elements 5 are formed in the pixel regions separated by these barriers 4. The formation of the barriers 4 is executed by first applying and forming resist films on the transparent conductive film 3 and removing the resist films of the portions where the patterns corresponding to the barriers 4 are opened by irradiation with UV rays. When the glass substrate 2 is immersed into a solution containing an electrodeposition resin and voltage is impressed between the electrodes disposed in the solution and the transparent conductive films 3, the electrodeposition resin moves near to the transparent conductive films 3 and gradually condenses.  The films of the electrodeposition resin are thus formed on the transparent conductive films 3. The resist films exclusive of the films of the electrodeposition resin are removed, by which the barriers 4 consisting of the electrodeposition resin are completed.
