Title: Construction of underwater wells
IPC: E21B43/013
Filed: 1981-06-01
Abstract: A method and apparatus are disclosed whereby a multiple tubing hanger (1) can be landed in an underwater well and a drilling upper body can be replaced by a production upper body (310) such that flow passages (324, 325) in the production body are correctly aligned with flow passages in hanger. In order to do this, a handling tool is connected to the hanger with a spline of the tool engaging gaps in a flange of the hanger and the handling tool is keyed to the drilling body as or after the hanger is lowered so that the hanger is landed in a known orientation. The tool and drilling body are then removed. The production body (310) is then lowered in approximately the correct orientation until it has approached the hanger (1). The production body is then rotationally adjusted so that splines (314, 315) of the production body engage the gaps in the hanger flange and the production body can then be landed with the flow passages (21, 22, 324, 325) aligned. <IMAGE>

Title: Semiconductor lasers
Inventor: NELSON ANDREW WILLIAM
IPC: H01S5/12
Filed: 1984-04-18
Abstract: In a distributed feedback semiconductor laser it is the upper face (10) of the upper confinement layer (1) which has the distributed feedback corrugations. This face is electrically isolated, for example by means of a dielectric layer (6). Contacting means (4, 5) are provided whereby a current can be made to pass across a p-n junction, for example the interface between the active layer (2) and the lower confinement layer (3), so as to cause lasing in the active layer. This structure permits a sequence of fabrication steps in which there is no need to overgrow corrugations with semiconductor. This avoids the possible risk of deformation of the corrugations. The laser is suitable for use in optical communications. <IMAGE>

Title: Front and rear wheel steering apparatus
Inventor: MIMURO TETSUSHI
IPC: B62D7/15
Filed: 1985-02-27
Abstract: When the difference between front and rear wheel steering angles exceeds a predetermined value, the rear wheel steering means is actuated to eliminate the difference. The predetermined value is modified in response to vehicle speed and defending upon whether the vehicle velocity is low or high, the rear wheels are steered in the same sense as the opposite sense to front wheels. If the gear transmission unit is set in a high velocity mode (by detecting position of shift lever), the rear wheels are steered to a neutral position. The rear wheel steering means can be locked in the neutral position and this locked condition detected to modify the steering signal. A time delay is introduced to inhibit a steering signal for the rear wheels if the lock signal is not received. <IMAGE>
