Patent GB-2129217-A (GB)
Title: Photolithography
Inventor: OH KYE HWAN
IPC: H01L21/027
Filed: 1983-10-26
Abstract: Photoresist patterning of fine lines and spaces by optical lithography at the metal level is impaired by the existence of standing waves in the photoresist, which are caused by reflections from the metal surface. These reflections can be reduced by interposing a sputtered polysilicon antireflection coating between the metal surface and the photoresist layer to provide optical matching. Optimum thicknesses are determined for the polysilicon layer to achieve minimum reflections. Demonstrations show that polysilicon or aluminium reduces reflectance, gives better line width control and has better gold wire bondability as compared to bare aluminium. <IMAGE>
Patent GB-2135594-A (GB)
Title: Ribbon growth of crystals
Inventor: SACHS EMANUEL MICHAEL
IPC: C30B15/00
Filed: 1984-01-12
Abstract: A method and apparatus for stabilizing the edge positions of a ribbon drawn from a melt includes the use of wettable strings drawn in parallel up through the melt surface, the ribbon being grown between the strings. A furnace and various features of the crucible used therein permit continuous automatic growth of flat ribbons without close temperature control or the need for visual inspection. A method and apparatus for minimising the introduction of impurities from the melt into a ribbon are desired. In such a method the melt is constantly flowed under the growth interface in a direction substantially perpendicular to the plane of the ribbon being grown so that the impurities that build up by segregation of impurities at the growth interface are removed.

Patent GB-2138593-A (GB)
Title: Handling Surplus Lengths of Optical Fibers at Cable Connection Points
Inventor: HARAGUCHI MASAKICHI
IPC: G02B6/44
Filed: 1984-04-05
Abstract: Surplus lengths of optical fibers (20, 20') are handled at a junction region at which optical cables (10, 10') are joined whereby excessively small radii of curvature of the fibers are prevented and numerous cut-and- splice operations can be performed without substantially increasing the losses in the fibers. If a sufficiently long surplus length of each optical fiber is available, each optical fiber is wound around a spacer (11) in a complete loop, preferably, through one and one-quarter turns. If a loop would extend along less than one-half the length of the spacer, the fibers are wound around the spacer in the longitudinal direction thereof through three-fourths of a turn without making a loop in the fibers. <IMAGE>

Title: Crank mechanism
Inventor: MANTOVANI BRUNO
IPC: B60S1/18
Filed: 1984-05-23
Abstract: A crank mechanism for moving the blades of a windscreen wiping mechanism to a parking position displaced with respect to its normal stop position has a crank which is formed of two parts (1, 2) which are interconnected by a hinge (C). One coupling end (1b) is flat, while the other is fork- shaped (2a, 2b) to receive and guide the flat end. The flat end has two radial angularly offset shoulders (4, 5), abutting with corresponding radial shoulders (6, 7) in the fork bottom. Because of the shoulders, during the normal operation of the windscreen wiping mechanism, the two crank parts assume an angled configuration, while, when the wiping mechanism is operated to move the blades to the parking position, by reverse rotation of the driving electric motor, these parts are arranged in aligned relationship and the blades reach the parking position by an additional stroke. <IMAGE>

Title: Measuring transmittance of a material
Inventor: HENRY BRADLEY JAMES
IPC: G01N23/08
Filed: 1984-09-19
Abstract: An apparatus and method for quantifying the transmittance of an object and further determining multiple attributes of the object therefrom include a radiation source which generates a radiation field which is exposed to the object through the top of the cabinet 11. A spot scanner 13 detects variations in the intensity of the radiation field and generates electrical signals proportional thereto, which are received by a computer console 15 which thence determines the transmittance of the object 90 and multiple product attributes. The source includes an X-ray tube 16 enclosed within container 12 and a cabinet 11 which holds the container 12 on a preselected axis and thereafter allows rotation of the container 12 through an angular displacement relative to the preselected axis. The spot scanner 13 includes a rotation element bearing radiation sensors in a plane intersected by the radiation field. <IMAGE>

Title: Circuit arrangement for an apparatus with a picture and/or a sound signal channel
Inventor: HALBE MANFRED
IPC: H04N5/44
Filed: 1985-07-31
Abstract: A circuit arrangement for use in a home-entertainment apparatus, has a memory 11 and a timer 10 so as to ensure that the apparatus can operate correctly only if a date has been entered in the memory. If a date is not entered, the timer will disable the apparatus after a specific time interval. After such a time interval the timer 10 turns on transistor 101 so as to mute a muting stage 5. If however the date has been programmed into memory 11, such as by interrupting appropriate electrical connections (15, 16, 17, Figures 2a, 2b) of the memory, the timer does not receive any power supply via 13 and the muting stages is set to low attenuation. As an alternative to the radio described in Figure 1 an audio channel of a record player, a recorder or a television receiver or the video channel of a television receiver may be controlled in a similar way. The memory 11 may be a microcomputer (2, Figure 3) using a EAROM memory with a keyboard (23) and display (22) for setting the date. <IMAGE>
