Title: Production of electrophotographic transparent transfer paper
Inventor: SUZUKI KUNIO
IPC: D21H15/00
Filed: 1995-01-20
Abstract: PURPOSE: To make it possible to improve transparency, lessen dimensional fluctuations, curls and undulations after thermal printing with an electrophotographic copying machine and to prevent the generation of smell by drying a sheet after sheeting down to moisture below a specific value, then spraying satd. steam thereto before a size press. CONSTITUTION: This transfer paper is produced by using pulp beaten down to Canadian standard freeness of <=20ml to make the sheet, drying the paper down to the moisture of <=10%, spraying the satd. steam thereto, subjecting the sheet to a size press treatment after lapse of >=1sec and within 5sec and drying the sheet with a cylinder drier. The swelling effect of the sheet is not exhibited and the formation of the undulations after thermal printing with the electrophotographic machine is not lessened if the size press treatment is started within 1sec after the satd. steam spraying.  The decrease in the moisture by the evaporation from the sheet surface is no longer negligible, a sufficient remoistening effect is not obtainable and the formation of the undulations after thermal printing with the electrophotographic machine is not lessened if the size press treatment is started after lapse of >=5sec from the satd. steam evaporation.

IPC: H01J1/28
Filed: 1978-01-25
Abstract: PURPOSE: To obtain a high-current density and long-life mold cathode which is excellent in ion-impact resistance and in residual poisoning resistance, by fixing the maximum diameter of a region composed of an alkali earth metal compound within a range from 5 to 20μm.  
     CONSTITUTION: As for the cross section of the mold cathode, area 9 is occupied mainly by an alkali earth metal compound, area 10 is by high-fusion-point metal, and area 11 is the largest diameter area of area 9. Decreasing the size of an area below 25μm makes it possible to make small the exhalation. In general, the life of a mold cathode is more than 3000 hours at a cathode temperature of 1300°K. As a result, the temperature should be below 1300°K in case of the use as a hot cathode while maintaining 1.2A/cm 2 , so that the size of area 9 should be of 5 to 20μm.

IPC: G06F11/28
Filed: 1987-01-19
Abstract: PURPOSE:To effectively detect the factors of program errors by showing the relationship among a reference variable and a substitution receiver variable as well as a program element which uses these variables when the program is tested and debugged. CONSTITUTION:A program executing part 1 reads a source program for interpretation and execution. If a substituted sentence is carried out to the specific test data during execution of said operations of the part 1, a using sentence variable memory part 2 stores the sentence number, the substitution receiver variable and the reference variable into a using sentence variable correspondence table 3. At the same time, a variable is supplied to a variable name searching part 4 from a keyboard via a variable name input part 6. The part 4 searches the number of the sentence including said variable out of the table 3 and delivers it to a program display part 5. Finally a display shows the source program given from the part 5 and displays a sentence using the input variable in a color. In such a way, the factors of program errors can be effectively detected since the relation of the variable influences can be detected and displayed.
