Title: Manufacture of phosphor for dispersing el
Inventor: ITO HIROYASU
IPC: H05B33/14
Filed: 1991-12-25
Abstract: PURPOSE:To provide a phosphor of long life by freezing-vacuum dry processing the phosphor after baking, so that adsorbed moisture on a surface of the phosphor can be removed. CONSTITUTION:Respectively 1mol% CuSO4.5H2O and 10mol% MgCl2 are added to a base body material ZnS to perform baking in the atmosphere for five hours at 1100 deg.C. This material is washed, and after cleaning MgCl2, the second time baking is performed in the atmosphere for three hours at 700 deg.C. Next, the material is washed for one hour by a water solution HC1 of 6N at 60 deg.C, and further washed for one hour by a water solution of KCN at 50 deg.C. Thereafter, the material is washed till washing obtains pH7 and dried. Next, an obtained phosphor is frozen at -40 deg.C, immediately stored in a closed vessel and placed in a 1TORR vacuum condition. And then, the material is further vacuumized and heated for 24 hours at 50 deg.C by radiation heat. Thereafter, after cooling to a room temperature, N2 gas is introduced into the vessel to a normal pressure to obtain the phosphor. In this way, adsorbed moisture on a surface of the phosphor can be removed to improve brightness and further to obtain the phosphor of long life.

Title: Production of pellicle and pellicle obtained by that method
Inventor: HONDA EIJI
IPC: G03F1/62
Filed: 1996-12-09
Abstract: PROBLEM TO BE SOLVED: To enable production of a pellicle by using an org. solvent soln. of a cellulose deriv. which can be easily filtered without using a separation precipitation method, by using a kneaded cellulose deriv. SOLUTION: In a pellicle having a cellulose deriv., the pellicle film is formed by using a cellulose deriv. which is subjected to kneading treatment. Thereby, filtering property of the cellulose derive. is significantly improved, and the obtd. pellicle has little oreign matters and high transmittance for light. The filtering property is significantly improved because by kneading the cellulose deriv., molecular chains of the polymer in a high mol.wt. region of the cellulose derive. are cut. The kneading temp. is preferably higher than the melting point of the cellulose deriv. The pellicle is obtd. by dissolving the kneaded cellulose deriv. in an org. solvent to prepare a soln., filtering the soln., and applying the filtered soln. on a substrate to form a cellulose ester thin film, and then peeling the thin film from the substrate.

Filed: 1989-12-29
Abstract: PURPOSE:To allow ordinary reading out and writing operations regardless of the level of an external terminal for writing control by providing a reading- out output circuit to be exclusively used separately from an output circuit for executing ordinary reading out at the time of reading out the non-volatile memory information of a programmable circuit inducing a fuse. CONSTITUTION:The output SW of a selecting switch signal generating circuit 3 rises to a high level and the MEMO of the non-volatile memory circuit 4 is transmitted to the output circuit 2 when a power source is turned on while the external terminal for writing control is at a high level. The same data as the data of a MEMO appears at the external input terminal IN. The SW is made to a low level, the output of a NAND circuit 5 to a high level, and the output of a NOR circuit 6 to a low level upon starting of the first writing operation after the external terminal for writing control falls thereafter to the level. A P channel type MOS transistor QP1 and an N type MOS transistor QN1, therefore, turn off. The output circuit 2 is thereafter held always in a disable state. The ordinary reading out or writing operation is executed in this way.

Filed: 1991-12-25
Abstract: PURPOSE:To mount a cathode simply and accurately to a grid by fixing the two ends of cathode to a base through a support, and installing the base removably to the grid. CONSTITUTION:An insulator 18, support 16, and cathode 3 are mounted on a base member 26. At this stage, the position relationship of constituent elements is set through precision measurement. After position setting, the base member 26 with elements mounted is installed to a grid 5. At this time, the base member 26 is arranged along guides 27, 28, 29 and then secured to the grid 5 using screws 30-33. Because the guides 27-29 are first located precisely and secured to the grid 5, the position relationship between the grid 5 and base member 26 can be kept accurately. This simplifies the works of position coordination and facilitates cathode change operation.

Abstract: PURPOSE:To adjust to easy-to-converge and well-balanced output by adjusting a parameter so as to minimize the value of a loss function decreasing with the increase of the difference between an output vector and a bad example teacher within teacher signals. CONSTITUTION:A loss function calculating means 8 is constituted of the loss function calculating means 9 by a model teacher and the loss function calculating means 10 by the bad example teacher. In this case, the bad example teacher within the teacher signals is defined as data not to be outputted as the output vector, therefore, to be avoided. Then, by the difference (x) between the bad example teacher and the output vector, the loss function (r) for decreasing along with the increase of the difference (x) is calculated with an equation (r)=exp(-x<2>). Then, when the value of the loss function is larger than a prescribed value, a control parameter is updated so as to reduce the value of the loss function until the value of the loss function becomes smaller than the prescribed value, the loss function is repeatedly calculated and when the calculated loss function reaches the value smaller than the prescribed value, the latest updated control parameter is integrated into the learning machine.
