Filed: 1986-07-22
Abstract: PURPOSE:To suppress the reduction of the conversion speed and improve the input operability for single Kanji (Chinese character) conversion processing by complementing the clause conversion processing with the single Kanji conversion processing. CONSTITUTION:The input character string from a keyboard 10 is stored in an input memory 11. When a clause conversion key is inputted from the keyboard 10, a clause conversion processor 13 executes the clause conversion processing of the input character string in clause units. If the conversion result is unsatisfactory, the single Kanji conversion processing is started. That is, a single Kanji conversion processor 14 performs the single Kanji conversion processing of the input character string stored in a memory 11 when the key which indicates the single Kanji conversion is inputted from the keyboard. Since the clause conversion processing is complemented with the single Kanji conversion processing in this manner, the reduction of the conversion speed is suppressed and the input operability for single kanji conversion processing is improved.

Title: Gas-discharge type display device
Inventor: IJUIN MASAHITO
IPC: H01J11/36
Filed: 1998-06-19
Abstract: PROBLEM TO BE SOLVED: To prevent the breakdown voltage failure and to improve the luminance by forming a reflecting film layer containing a white material over the sidewall surface of a bulkhead and the bottom surface between bulkheads so as to be in contact with a phosphor layer on a back substrate. SOLUTION: A reflecting film layer 5 formed on the sidewalls of a bulkhead 4 and the bottom surface of a discharge space partitioned by the bulkheads 4 is covered with a phosphor layer 6. The reflecting film layer 5 is formed by thick film printing of a dielectric paste containing an inorganic component made of only a white material. In this way, light emitted by the phosphor by ultraviolet ray excitation caused by the discharge within the discharge space is prevented from being transmitted or absorbed by a glass substrate 1 or the sidewall surfaces of the bulkheads 4, and the light can be reflected to the front substrate side that is the display surface side. Thus, the loss by transmission or absorption can be prevented, and the emitting quantity to the display surface side can be improved by reflection to improve the luminance.  Since address electrodes 2 are covered with a dielectric layer 3, the breakdown voltage can also be improved.
