Abstract: An improved method of scheduling a meeting among terminal users who are provided with calendaring applications for storing and retrieving timed and dated events. A prompting screen is presented to a meeting scheduler with blanks for keying in desired times, dates, and prospective attendees for a meeting. In response to the schedulers keying to this screen, a comparison is made with the calendar of events for each prospective attendee. As a result of the non-availability of a meeting time which complies with the desired times, dates and attendees, these factors are automatically altered or "relaxed" in order to achieve an acceptable meeting time. An option list of meeting times is then presented to the scheduler for selection of a meeting time. Based upon the selection of the scheduler, a meeting notification screen is then constructed for transmittal to each attendee.

Abstract: The slide (12) is mounted on the frame (10) so as to be movable back and forth in the direction of the arrow (A, B). Arranged on said slide are the two deflection cylinders (16, 18) which bound the gap- shaped passage opening (24) for the web of material (60) fed from below. The continuous belt (30) is guided around the deflection cylinder (16) and deflected via two deflection rollers (20, 26) to balance out the length. The second belt (32) is of continuous construction, guided around the deflection cylinder (8) and guided sinusoidally around the deflection rollers (22, 28) to balance out the length. Furthermore, the belt (32) is deflected via the two cylinders (38, 40) mounted on the frame (10), between which cylinders the clamping device (42) is arranged. Provided on the slide (12) are two clamping arrangements (44, 46). For the folding and stacking of the web of material (60) the clamping device (42) clamps the belt (32). For guiding the completed stack (56) away in the direction of the arrow (F), with the slide (12) situated in the right end position (12') the clamping arrangement (44) is activated, by which means during the movement of the slide (12) in the direction of the arrow (B) the stack (56) is carried along. Then the clamping arrangement (44) is released and clamping arrangement (46) is activated, by which means during the movement of the slide (12) in the direction of the arrow (A) the stack (56) is conveyed further away in the direction of the arrow (B). For the formation of a new stack, the clamping device (42) is once more activated and clamping arrangement (46) is released.

Abstract: A method of manufacturing a semiconductor device comprising the steps of forming selectively an insulat­ing layer (34) on a first conductive layer (33) depo­sited on a semiconductor substrate (31), treating the surface of the insulating layer (34) and the exposed surface of the first conductive layer (33) by a gas plasma containing halogen atoms, and depositing selec­tively a conductive material by vapor growth on the exposed surface of the first conductive layer (33) so as to form a second conductive layer (36). The gas plasma containing halogen atoms can be formed by introducing a gas containing halogen atoms into the treatment chamber housing the sample, and applying high frequency power. The gas plasma containing halogen atoms can be formed by introducing a gas containing halogen atoms into the treatment chamber to adsorb the halogen atoms on the inner wall of the chamber, and applying high frequency power. Alternatively, the gas plasma can be formed by applying high frequency power after placing the sample and a halogen containing material inside the chamber. By treatment with the gas plasma containing halogen atoms, a second conductive layer (36) can be deposited with good selectivity.

Abstract: A second bar code such as an add-on code which comprises only a character bar and is added to the side of the first bar code such as UPC, EAN and JAN and having a center bar and a guard bar can be correctly read out. When the scanning is made from the first bar code side to the second bar code side, a write address produces, when the right guard bar of the first bar code is recognized, a signal which is used to access the data of the second bar code. Conversely, where the scanning is made from the second bar code side to the first bar code side, the write address produces, when the center bar of the first bar code is recognized, a signal which is used to access the second bar code after subjecting to some arithmethic operation. Therefore, the first bar code can be clearly distinguished from the second bar code which is different in the bar code system and the second bar code can be correctly read out.
