Patent EP-0362867-A2 (EP)
Inventor: ABE MASAHIRO INTELLECTUAL PROP
IPC: H01L21/027
Filed: 1989-10-06
Abstract: A method for manufacturing semiconductor devices comprising the steps of forming a first wiring pattern including first and second lower layers (11A, 11B) on a semiconductor body, forming an insulation film (14) which covers the first wiring pattern, forming a first hole (13B) of 1.5 µm and a second hole (13A) of 3 µm in first and second areas of the insulation film (14) which lie over the first and second lower layers (11A, 11B), forming a second wiring pattern having first and second upper layers (12A, 12B) respectively connected to the first and second lower layers (11A, 11B) via the first and second holes (13A, 13B). In the method, the hole formation step includes the sub-steps of forming a resist film which covers the insulation film (14), forming a resist pattern by effecting the photolithographic process of exposing the insulation film (14) to light by using a mask pattern having a first hole defining area of 1.5 µm and a second hole defining area of 2.4 µm, and etching the insulation film with the resist pattern used as a mask. The exposing light amount used in the resist pattern formation sub-step is previously determined so that the size of the first hole can be set equal to that of the first hole defining area, and the reduced amount of the second hole defining area is previously determined so that the size of the second hole obtained under the determined exposing light amount can be set to 3 µm.

Abstract: A photographic reversal process for producing positive photographic images by imagewise exposure of the light-sensitive material containing at least one silver halide emulsion layer, first black-and-white development of the material, chemical fogging or diffuse second exposure and subsequent colour development, characterised in that
 1. at least one N,N-dialkyl-p-phenylenediamine derivative is exclusively used as the developer in the first development,
 2. the first developing bath contains at least one compound which prevents coupling of the developer oxidation product formed in the first development with the colour couplers present in the colour-photographic reversal material to give image dyestuffs,
 3. the silver halide emulsion layers of the photographic material have a chloride content of at least 80 mol%, proves to be particularly suitable for rapid development of reversal materials due to elimination or shortening of the washing step between the first and second developer, without this causing disadvantages with respect to the quality of the colour images produced by this process.

Abstract: An identification system for personal, freight items and such like comprises a tag-like electronic responder device (1) which comprises an antenna (4a, 4b) which reflects, and thereby modifies, an electrical wave incident thereon from a separate interrogator device. The device (1) modifies the reflection in accordance with binary data generated by data generating means (9) by varying the impedance loading of the antenna (4a, 4b) by switching a FET (8) in accordance with the binary data. The binary data may comprise identification data as well as synchronising data for decoding purposes. The responder device (1) may be reprogrammed with new identification data by means of a programmer.

Abstract: There are described a surgical catheter (10) and a method that removes stenosis and prevents restenosis. The catheter comprises a laser-emitting device (110), most preferably a laser diode, in the distal end (20), whereby optical fibers and their attendant disadvantages are eliminated. Preferably, the diode (110) is coupled with a mechanical cutting edge (56), so that the diode (110) can expose to low power laser light (130) freshly exposed, healthy luminal surfaces (S). Such exposure devitalizes and seals such surfaces to substantially prevent restenosis.

Abstract: The present invention relates to ion-conducting solvent-free polymeric systems characterized as being cationic single ion conductors. The solvent-free polymer electrolytes comprise a flexible polymer backbone to which is attached a metal salt, such as a lithium, sodium or potassium salt, of a sterically hindered phenol. The solid polymer electrolyte may be prepared either by (1) attaching the hindered phenol directly to a flexible polymeric backbone, followed by neutralization of the phenolic OH's or (2) reacting the hindered phenol with a polymer precursor which is then polymerized to form a flexible polymer having phenolic OH's which are subsequently neutralized. Preferably the hindered phenol-modified polymeric backbone contains a polyether segment. The ionic conductivity of these solvent-free polymer electrolytes has been measured to be in the range of 10⁻⁴ to 10⁻⁷ S cm⁻¹ at room temperature.

Abstract: A snap-acting bimetal blade for use as a thermally-responsive switch actuator has a generally rectangular outer shape and has a generally rhomboidal cut-out defining two spaced-apart and tapering legs connected together at their opposite ends. Such a blade shape has advantageous characteristics as regards the forces and movement that can be developed in switching operations. A thermally-responsive switch incorporating such a bimetal blade has first and second spaced-apart metal parts, one of which is formed of rigid, electrically-resistive material and the other of which is a spring member, first and second contacts provided on such parts, a bimetal blade as aforesaid welded to one of the parts, and an insulating push rod arranged for transferring switch-­operating movement of the bimetal to the spring member for operating the switch. When used as a motor protection switch, the bimetal operation is dependent upon heat generated by current flow in the electrically-resistive part of the switch and the switch can be made relatively insensitive to large currents flowing for short durations, but sensitive to   longer term lower currents, and can have a high ratio of "off" time to "on" time.

Abstract: In an Oldham-type disc coupling for the connection of components which are misaligned in parallel, the intermediate ring, which is freely movable between the hubs of the two components to be coupled, carries on each of its plane sides two strips which are less than 90 DEG relative to one another and which engage in corresponding grooves of the hubs. The strips are curved convexly at their friction surfaces and the supporting walls of the grooves are correspondingly shaped concavely for receiving the strips. An Oldham-type disc coupling of this type is particularly suitable as guide and rotation-inhibiting means for the revolving displacement elements of a rotary piston machine of the positive displacement design. <IMAGE>

Abstract: There is provided a metallic tape supporting a mercury vapour releasing material, preferably Ti₃Hg, admixed with a non-evaporable getter metal, preferably an alloy of 84% Zr - 16% Al, contained within a continuous series of depressions within the tape. The depressions form a successive series of pairs of depressions preferably each having an oval shape. Each pair of oval shaped depressions is separated by a distance greater than the distance separating the individual oval shapes. The tape can then be cut between each pair of depressions to form a small strip containing two depressions. Such a small strip can then be folded through an angle of approximately 180° about an axis, in the plane of the tape midway between the depressions, perpendicular to the tape length. This folded strip can then be welded to a support and used as a cold cathode electrode in a miniature fluorescent lamp. The cathode can be heated during a manufacturing process to release mercury and subsequently act as a cold cathode and getter device.

Abstract: A trigger switch for hand-held electric power tools in which an actuating arm for actuating a switch mechanism is pivotally supported in a case by way of a pivot shaft (12) pivotally supported by a pair of parallel lateral walls defining the case (11), and a trigger member (32) having a front end and a pair of lateral flanges is pivotally supported by the case in a coaxial relationship with the pivot shaft by way of the lateral flanges. By securely coupling an extension of the pivot shaft with one of the flanges, the switch mechanism internally accommodated in the case can be actuated by operating the trigger member. Since the switch mechanism is internally accommodated in the case, a considerable saving of space can be accomplished. Since the coupling between the pivot shaft and the trigger member can be accomplished by the extension of the pivot shaft passed through the case by way of a round opening provided in the case, sealing of the switch mechanism can be easily accomplished.
