Title: Method for cold rolling dense hexagonal metal sheet
Inventor: NISHIMURA TAKASHI
IPC: B21B3/00
Filed: 1984-07-11
Abstract: PURPOSE:To obtain a metal sheet having a good surface quality with good productivity without forming oil pitch, by cold rolling a dense hexagonal metal sheet by using an emulsion type lubricant contg. an oil disperse phase having a specified median particle size and a specified degree of saponification. CONSTITUTION:A dense hexagonal metal sheet is cold-rolled by using an emulsion type lubricant contg. an oil disperse phase haing a median particle size of 6mu or below and a degree of saponification of 80 or above. The emulsion lubricant having a median particle size of 6mu or below can be prepd. by adding an anionic, cationic or ampholytic hydrophilic group-contg. surfactant to oil to thereby form an emulsion contg. oil particles uniformly dispersed therein. When the lubricant has a degree of saponification of less than 80, rolling pressure is too high and difficulty ariser in carrying out rolling, while when the degree of saponification is 80 or above, an increase in rolling pressure is relatively gradual and the average rolling pressure reaches its peak at a pressure of 170kg/mm.<2> or below and is no longer increased, even when rolling reduction is increased.

Title: Information display system
Inventor: DEBITSUTO EDOWAADO PENA
IPC: G06F3/037
Filed: 1983-08-10
Abstract: An information display system which can produce an information display (e.g. on a television monitor) from any one of a plurality of different information sources. The information sources are associated with different facilities such as teletext and viewdata. For obtaining information from a particular information source the associated facility option is selected. This selection is made from the available facility options by selecting from the television screen "nested" areas which pertain to one or more facility options. The selection can be effected using a touch-sensitive screen which overlies the television screen. The selection process can involve the display of a number of successive display frames containing "nested" areas, the selection of an area in one frame causing the display of a fresh display frame which re-defines areas which are nested within the selected area.

In a sample chamber 1b, only a small amount of the reactive gas molecules in vapor phase can exist, and the inside of the sample chamber 1b is considerably highly vacuumized, by continuing the exhausting with the exhausting equipment 6. When the substrate is irradiated with energy beam by opening a shutter 15 by a necessary amount, the reactive gas molecules in liquid phase or solid phase are made to react chemically, and a thin film composed of reaction products is formed on the substrate. Thereby, a manufacturing equipment for thin film can be obtained which can collectively expose a large area without contaminating the substrate.
