Title: Transmission control apparatus of infinitely variable transmission
Inventor: MIYAURA YASUHIKO
IPC: B60W30/18
Filed: 1985-08-28
Abstract: A transmission control apparatus of an infinitely variable transmission (103) for electronically controlling the operation of the infinitely variable transmission (103) in response to transmission control information including a throttle opening position, etc., calculates a transmission operation command value by looking up a transmission control information-control command value conversion storage table based on the transmission control information. Correcting means (107) compares the transmission command value with the actual ratio and ratio change is prevented if this difference is less than a predetermined value or, if it is greater than a predetermined value, is limited to this value in a single cycle of the controlling computer program, to prevent shock and for hunting. Control means (104) controls the transmission operation of the infinitely variable transmission (103) in accordance with the corrected ratio change, and thus smooth and stable transmission operation is achieved. <IMAGE>

Patent GB-2192491-A (GB)
Title: Stabilised mount
Inventor: ROGERS NEVILLE
IPC: G01C19/26
Filed: 1986-07-12
Abstract: A stabilised mount [e.g. for an antenna (13)] has two gyroscopic rotors (23, 24) mounted in such a way that they can pivot about orthogonal axes (26, 27). Rewinding of the antenna (13) (to avoid undue twisting of the electrical cables) is liable to cause a violent destabilisation of the mount because of the gyroscopic action of the rotors (23, 24). To prevent this destabilisation the rotors (23, 24) are locked against the aforementioned pivotting action during the rewinding procedure.

Title: Sound absorbing floor
Inventor: MACKENZIE DR ROBIN KENNETH
IPC: E04F15/20
Filed: 1986-07-24
Abstract: A floating raft construction for laying on top of concrete slab or timber joist structural floors is designed primarily to attenuate airborne sound whilst also providing for the isolation of impact sound. This system comprises of chipboard flooring laid upon and nailed to a series of timber battens to which a lamination of open cell polyether and closed cell polyethylene foams have been bonded. The open cell structure of the polyether foam permits the attenuation of acoustic energy in the cavity between the battens by dissipation within the interstices of the foam itself. The high mechanical strength of the polyethylene strip provides the softer polyether foam with protection from tear. In addition to the airborne sound attenuation properties, the floor also provides the resilience necessary to isolate impact sound from being transmitted into the structural floor. <IMAGE>

Patent GB-2180693-A (GB)
Title: Semiconductor structures
Inventor: SCOVELL PETER DENIS
IPC: H01L29/08
Filed: 1986-10-01
Abstract: A heterojunction structure comprising a well extending into a region of a substrate from the surface, the region being of one conductivity type (8) adjacent the well wall, and a layer of material of opposite conductivity type (10) being deposited in the well in contact with the well wall. The structure can be employed in, for example, a CMOS-compatible bipolar lateral transistor, where a base region (8) is formed at the walls of a hole-like well etched into an n-type well (16) of an n-well CMOS integrated circuit formed in a silicon semiconductor substrate (2). A deposited emitter (9) extends into the well and partially over the surface of masking layers (1,3) provided on the substrate (2), and is in contact with the base region (8). The deposited emitter (9) may comprise a doped-SIPOS (semi insulating polycrystalline silicon) layer 10 and a conducting polycrystalline silicon layer 11, or a doped single layer of polycrystalline silicon. An oxide layer (6) provides isolation preventing downward injection and ensuring good lateral operation. The heterojunction enables lower base resistance to be obtained than in homojunction devices by allowing high base doping. Such a lateral transistor structure requires only two additional maskings in comparison with conventional CMOS processing and, due to the use of a well, has a self-aligned action region. <IMAGE>
