Title: Low Loading Trailer
IPC: B62D53/06
Filed: 1978-07-17
Abstract: A low loading trailer is constituted by a load carrying platform A and a chassis B connected to the platform by means of a frame C. The chassis B is provided with wheels 11. The frame C is pivotally connected to the chassis B and is slidable relative to the platform A whereby the chassis can be moved between a towing position, in which the chassis is positioned substantially centrally of the platform and the platform is supported by the chassis above the ground, and a loading position, in which the chassis is positioned at the rear of the platform and the platform lies on the ground. Thus, in the towing position, the wheels 11 supporting the platform A are centrally positioned, which result in a relatively small turning circle. <IMAGE>

Title: Method of making a pipe coupling and method of curing a polyester resin body
IPC: F16L21/00
Filed: 1979-05-21
Abstract: A pipe coupling comprises a body of fiber glass reinforced plastic which has a rubber sleeve embedded therein. The sleeve is a one piece unit which includes specially shaped sealing gaskets on either end and has a rubber liner spanning the area between these sealing gaskets. The sleeve is stretched onto a steel and plastic molding mandrel, which places the rubber liner under tension, reduces the cross- sectional area of the liner and compensates for thermal expansion of the liner during curing. The mandrel/sleeve combination is rotated in order to wind a thermosetting resin impregnated fiber glass roving around the outer circumference of the mandrel/sleeve combination, thus embedding the sleeve in the fiber glass reinforced resin matrix. The thermosetting resin is cured at elevated temperatures, hardening into a rigid coupling with the embedded rubber sleeve integral therewith. Thereafter the hardened coupling is stripped from the steel and plastic mandrel and subjected to a further curing and finishing operation. The curing of a polyester body with a peroxide while in contact with a rubber surface is also claimed.

Title: A shallow channel field effect transistor
IPC: H01L29/417
Filed: 1981-01-28
Abstract: A field effect transistor has an elongate buried region 30, of opposite conductivity to the semiconductor layer 12, formed below the gate electrode 44. The buried region which forms a bottom gate electrically connected to the top gate electrode, where it breaks through to the electrode at the edges of the mesa layer. With this arrangement the channel of the FET has a shallow depth in the semiconductor between the gate electrode 44 and the buried layer 30. The top gate may be of the insulated, Schottky or junction type. The FET is fabricated by forming a pair of masking strips 14, 16 of insulating material on the surface of the semiconductor, forming an ion implantation masking layer between the pair of masking strips and implanting particles to establish the source and drain regions 22, 24. With such method a single masking step is used to define the source, drain and gate regions of the device, namely the masking to define the strips 14 and 16. The buried layer is formed by deep ion implantation with the source and drain masked or without masking so that there is shallow implantation under the strips 14, 16 and deep implantation elsewhere. Gate oxide may be deposited between the strips before implantation. The device may be formed in a semiconducting mesa on a sapphire or similar substrate. <IMAGE>
