Abstract: PURPOSE:To accurately rotate an image carrier at a constant speed by rotating the image carrier by a driving device arranged in the vicinity of the carrier through a worm and a worm gear. CONSTITUTION:A double-spindle type drum driving motor 31 is used, the worm 40 is fixed to one driving spindle and the worm 40 is engaged with the worm gear 41 fixed to the end part of a photosensitive drum 11 to deceleratingly rotate the drum 11. Another worm 42 is fixed also to the other driving spindle on the other end part of the motor 31 to rotate a worm gear 43 for transmitting driving power to another rotating means by the worm 42. Thus, the driving device is arranged in the vicinity of the image carrier 11 and the drum 11 is deceleratingly rotated through the worm 40 and the worm gear 41. Consequently, a gear string from the driving device up to the image carrier can be reduced at its minimum and the image carrier can be rotated at the constant speed by the driving source.

Abstract: PROBLEM TO BE SOLVED: To enhance a heat transfer rate by reducing a dead water zone occurring on the leeward side of a tube. SOLUTION: A tube 3 has a circular inner cross-section (tubular inner circumferential surface 3a) and irregular outer circumferential profile. More specifically, front side (windward side) of the tube 3 facing the air flow is formed of an arcuate surface 3b having a constant thickness with respect to the tubular inner circumferential surface 3a and the rear side (leeward side) of the tube 3 is formed of two outer wall faces 3c extending in the direction of air flow. The outer wall faces 3c is formed of a convex surface extending in streamline shape from the left and right sides of the tube 3 with respect to the air flow while inflating gently outward and both outer wall faces 3c intersect at an acute angle to form a rear end part 3d. Since the air can flow smoothly along the outer wall faces 3c of the tube 3 on the opposite sides thereof, contact area (heat transfer area) between the tube 3 and the air increases thus enhancing heat transfer rate.

Title: Similar symbol linking method for executing format module generation
Inventor: NAKAMA HISASHI
IPC: G06F9/06
Filed: 1989-02-13
Abstract: PURPOSE:To generate an executing format module even when an intermediate format module in a different expression exists by regarding an English small letter and capital letter as the same in the expression of a symbol, and regarding the numbers of the letters as the same when the comparison of a constant effective length from the top corresponds to each other. CONSTITUTION:Software 3 reads an intermediate format module 1, and detects an external reference symbols ABC and A to H. Next, when the software 3 reads an intermediate format module 2, it detects area definition symbols abc and (a) to (j). Further the software 3 detects the expressions of the symbols of the respective modules 1 and 2, and when it identifies the difference between the expressions of the symbols, it compares the similality between the previously detected symbols ABC and A to H with abc and (a) to (j). At such a time, when the English small letters are compared with the English capital letters by regarding the formers as the letters, ABC corresponds to abc, and by comparing the effective length by regarding it as the top eight letters, A to H correspond to (a) to (j). Thus the linking processing is executed based on the coincidence result of the similarity comparison of the symbols, and an executing format module 4 is generated.

Abstract: PURPOSE:To obtain a reactive gas which has a slow etching speed, causes less damages to substrates, and is excellent in working shape, especially, in verticality by using a mixed gas containing an ethane gas and hydrogen gas as the etching gas. CONSTITUTION:At the time of etching a semiconductor material containing group VI element by using a reactive gas, a mixed gas containing an ethane gas and hydrogen gas is used as the reactive gas. For example, an etching mask 2 is formed on a ZnSe crystal 1 by using a photoengraving technique. Then, after putting the crystal 1 in the vacuum tank 3 of a reactive ion etching system and evacuating the tank 3, the ethane gas and hydrogen gas are respectively introduced into the tank 3 through introducing ports 4 and 5 as the reactive gas. When plasma is generated by applying a high-frequency voltage across facing electrodes 7, etching takes place in the window areas of the mask 2 where the mask 2 does not exists due to the reaction between the semiconductor material and plasma ions. It is necessary to set the mixing ratio of the ethane gas in the mixed gas to <=15vol.%.
