Title: Dry etching method and its pretreatment device
Inventor: KUBOTA MASABUMI
IPC: H05H1/46
Filed: 1991-11-18
Abstract: PURPOSE:To form a layer high in dry etching resistance, which includes bromine, at the surface of a photoresist mask, and raise the selection ratio with the photoresist effectively, by immersing the photoresist mask in solution while being exposed in the gas of bromine compound prior to dry etching. CONSTITUTION:A photoresist mask 13, which functions as a mask in dry etching, is made at the surface of a sample. And, a silicon substrate 10 is soaked in organic compound bromobenzene or bromoform and is let alone from several minutes to tens of minutes. Hereby, a layer 14, where carbon and bromine are coupled, is made at the surface of the photoresist pattern 13. A silicon substrate 10 being prepared this way is etched with an aluminum dry etcher. Since the layer 14, which contains bromine high in dry etching resistance, is made at the surface of this photoresist mask, the dry etching resistance of the photoresist can be improved.

Title: Power circuit for programmable controller
Inventor: HAMADA AKIHIDE
IPC: G05B19/05
Filed: 1991-11-18
Abstract: PURPOSE:To select and use a desired battery cassette in response to the using purpose of a programmable controller by attaching and detaching interchangeably both primary and secondary batteries to and from the programmable controller as the power supply used for the power failure. CONSTITUTION:The primary battery BAT1 of a primary battery cassette 10 supplies the power for the power failure to a memory 7 via the reverse current preventing diodes D1 and D2 which have the double constitutions for the prevention of the diode short circuits and a connector CN. When an internal power supply 6 stops its working, the supply 6 is switched toward the cassette 10 by a switch signal RESET before the working of the supply 6 is stopped. Thus, the memory 7 is set in a data holding state when a power failure occurs. In the case of a secondary power cassette 11, the power is supplied to the memory 7 from a secondary battery BAT2 against the power failure via the diode D1. In such a condition, a charging circuit 12 charges fully the BAT2 via a reverse current preventing diode D3 while the power supply 6 is used.

Title: Magnetic bubble magnifier
Inventor: YONENO KAZUNARI
IPC: G11C11/14
Filed: 1986-12-20
Abstract: PURPOSE:To improve the characteristics of a magnetic bubble magnifier by connecting the center parts of basic patterns via a bar-shaped pattern of a soft magnetic thin film and at the same time protruding said pattern to outside from both end parts of a pattern train. CONSTITUTION:The basic patterns 2 of chevron types, etc., made of soft magnetic thin films are set vertically to the bubble transfer direction. Thus a pattern train 3 is formed. Then the center parts of patterns 2 are connected together by a bar-shaped pattern 5 which is extended to outside from both ends of the pattern 3. Thus the patterns 2 are magnetically connected via the pattern 5 and therefore the magnetization concentrated at the head part of the pattern 2 is reduced. Then the interaction is reduced between an extended stripe magnetic domain and the pattern 2. As a result, the stripe magnetic domain is never branched and the malfunctions due to the tangle of bubbles. Thus the bubble transfer characteristics are improved.

Filed: 1988-11-29
Abstract: PURPOSE:To prevent the occurrence of chocking with pebbles in sewage by a method wherein an inner casing is contained in an outer casing provided at its upper part with a suction port and a delivery port, and an impeller extending through the bottom of the inner casing is mounted to the inner casing with a given distance between the outer casing and the impeller. CONSTITUTION:An inner casing 17 is mounted in an outer casing 10, a rotary shaft 18a is mounted to the inner casing 17 in a manner to extend through the bottom part thereof, and an impeller 24 is mounted to the rotary shaft. Thus, a given distance is provided between the impeller 24 and the outer wall of the outer casing 10. Sewage is sucked through a suction port at the lower end of the impeller 24 by means of a suction pipe 15 and is delivered in the outer casing 10 through a guide blade 25b to discharge it through a delivery port 13. This constitution always brings the impeller 24 into a submerged state and provides the size of a gap between the impeller and a surrounding member with a margin, prevents the occurrence of chocking with pebbles in sewage, and prevents lowering of the suction efficiency of the impeller 24 since sucked air immediately produces air bubbles because of a distance between the outer casing 10 and the impeller being wide.

Title: Plating treatment of drill screw
Inventor: ZAIKI MASAMI
IPC: F16B25/00
Filed: 1997-10-17
Abstract: PROBLEM TO BE SOLVED: To provide a plating treatment method which facilitates screwing work to works and yields drill screws of improved corrosion resistance. SOLUTION: This plating treatment method consists in first subjecting drill screw blanks formed with screw threads to galvanizing of a small thickness, then subjecting these blanks to a baking treatment in a next baking treatment stage 15 for the purpose of removing the hydrogen penetrated into the blanks in the first plating treatment stage 14, in succession, subjecting the blanks to galvanizing of a large thickness to make the thickness of the plating to >=20 μm in a second plating treatment stage 16. When the drill screws are used for a building structure of steel frame construction, the production time of the drill screws corresponding to its standards does not get longer and the relative inexpensive supply thereof is made possible. Since the plating is first applied in thin thickness and then, the plating in thick thickness, the hydrogen of the screw blanks is surely removed and neck jumping does not arise. Further, the thickness of the plating stabilizes and the performance as the drill screws is relatively uniform.
