Title: Automatic opening and closing sliding door device using tread pressure
Inventor: YAJIMA NOBORU
IPC: E05F13/04
Filed: 1999-03-24
Abstract: PROBLEM TO BE SOLVED: To open quickly a sliding door by expanding and converting the amount of movement of a swinger that swings following the sinking of a tread plate to a nearly straight motion with a linking mechanism and making it act on an operating arm. SOLUTION: When a person walking toward a doorway 10 treads a tread plate 2, a swinger 3 swings, rotating a lever 4 and conveys the rotation of the lever 4 to an A link rod 50 through a coil spring 42. At this time, the coil spring 42 extends, absorbing a slight rotation of the lever 4 and then shrinks at a stretch when a prescribed amount of extension is exceeded, and acts on the A link rod 50. The operating force of the A link rod 50 acts on an operating arm 6 through a B link rod 51, pulling and moving the sliding door 1 toward a door storage case 14, thereby moving quickly the sliding door 1 in the direction of opening sensitively responding to the tread on the tread plate 2.

Title: Manufacture of semiconductor device
Inventor: MATSUNO TOMOYUKI
IPC: H01L21/322
Filed: 1994-03-25
Abstract: PURPOSE:To effectively eliminate contamination and defect in an active region by front side gettering, without damaging the active region and contaminating the layer by the material from an ion implanter, by selectively ion-implanting material for gettering, in the surface part of the region except the active region of a wafer. CONSTITUTION:Material for gettering is selectively ion-implanted in the surface part of the region except the active region of a semiconductor wafer. For example, a resist film 2 is selectively formed on a semiconductor substrate 1, and the material for gettering such as carbon and oxygen is ion-implanted while the resist film 2 is used as a mask. Hence a getter layer 3 is formed in a scribe region 5 except the region turning to a semiconductor chip 4. It is preferable for the getter layer 3 to be formed in the initial process wherein a thick insulating film and other films are not present on the surface and it is comparatively difficult to prevent contamination. The energy and the dosage of ion implantation are changed according to the depth or the like of the active layer.

Title: Etchant for roughening aluminum electrode surface and etching method
Inventor: ASHIKARI TETSUYA
IPC: C23F1/20
Filed: 1998-03-27
Abstract: PROBLEM TO BE SOLVED: To facilitate the recognition of patterns in a second half stage by subjecting the Al electrodes formed by a multichamber system to surface roughening without changing the film quality of the Al by using BHF diluted with water as an etchant for surface roughening of the Al electrode surfaces. SOLUTION: The electrode form of LEDs is executed by using a multichamber system sputtering apparatus and continuously forming the respective TiN/Ti/Al electrodes. In such a case, the mirror finishing and hardening of the Al unaffected by impurities, etc., progress. The BHF which is the etchant heretofore used for surface roughening is diluted with the water in order to effectively roughen the surfaces of the Al films which are formed by sputtering with the multichamber system sputtering apparatus and are hard to be roughened in their surfaces. If the compsn. ratio of the BHF and the pure water is successively increased, the etching rate increases and the surface roughening progresses but if the rate is made too high, the variations within the wafer surfaces appear considerably and, therefore, the dilution of the BHF and the pure water is executed at a ratio of 1:1.
