Filed: 1985-04-25
Abstract: PURPOSE:To make it possible to resume sequence always from an initial state by initializing an address storing area by an initializing means when starting the sequence and obtaining the initialized address by an address inducing means. CONSTITUTION:A stack initializing section 2 initializes stack 1 and generates a starting signal 11 according to a starting signal 10 generated by resetting etc. On receiving this starting signal 11, a pre-arithmetic section 3 performs the first arithmetic processing and then generates a starting signal 12 and a pop-up section 4 pops up the stack 1. However, as the stack 1 is empty at this time, fixed address is selected and a starting signal 13 is generated. By this starting signal 13, a rear end arithmetic section 5 performs the second arithmetic processing and then generates a starting signal 14. A pushdown section 6 pushes down an address that makes the pop-up section 4 generate a starting signal 16 to the stack 1 as a signal 9 and generates a starting signal 15.

IPC: G01M9/06
Filed: 1981-06-11
Abstract: PURPOSE:To strip a discoloration reagent from test models easily and continuously upon ending of a test by coating a packing agent beforehand on the test model to form its film, and coating the discoloration reagent thereon. CONSTITUTION:A liquid type polyurethane resin type coating agent is used as a packing agent, and this is sprayed or brushed on the surfaces of test models and is dried and set by blasting or the like, whereby a continuous film is formed on the surfaces of the test models. A discoloration reagent is coated on the film of the packing agent, after which gaseous ammonia is discharged into a wind tunnel, and prescribed diffusion experiment is carried out. After the discolored areas and degrees of the discoloration reagent are observed and recorded, the reagent is stripped. It is a good practice to sprinkle powder beforehand thinly on the surfaces of the test models in order to improve the strippability of the discoloration reagent. Known reagents are usable for the discoloration reagent in correspondence to the gases to be discharged, and in the discoloration areas near neutral, bromthymol blue, phenol red, and cresol red are usable.

Abstract: PURPOSE:To make it possible to stably keep an initial good liquid droplet forming characteristic over a long period of time by imparting excellent synthetic durability to the titled recording head in frequent repeated use or long-time continuous use, by forming an upper layer by a bias sputtering method. CONSTITUTION:When RF power of 700W is applied to an SiO2 target with a dimension of phi8 inch and an SiO2 layer is formed by changing support bias in a range of 0-300V, the inclination at a step part becomes gentle as bias voltage becomes larger and the result of etching treatment shows a value almost equal to the etching speed in a flat part in all parts when no bias voltage is applied. A film forming speed is reduced as bias voltage is applied to a support but the inclination of the step part becomes gentle as bias is increased. From the relation of the effect of bias applied to the support and the required time of a film forming process by a film forming speed, bias is -100V--250V more pref.
