Title: Congestion control of a web server utilising the number of user terminals accessing web pages which have transition links to the web server
Inventor: HIDEYUKI KOTO
IPC: H04L12/24
Filed: 2009-03-31
Abstract: A control server 4, receives the number, U, of user terminals 1 which have transited to individual Web pages from a monitoring server 3 (S41, Figure 3). Based on the received number of transitions U of the individual Web pages, application of control is decided (S42, Figure 3) by the control server 4. Based on the assumption that the number of transitions Uc to a Web page C including a transaction access or hyper link to the end server 2 accurately represents the number of executed transactions on end server, the number of transitions Uc to Web page C is compared with an upper limit value Cmax. When Uc>Cmax control information is generated by the control server and applied to the user terminals, such as to suspend access requests to the end server. When Uc<Cmax, control information is sent from the control server 4 to the user terminals 1 to cancel the application of control (S43, Figure 3). This method is used to avoid congestion of an end server such as to control access requests to a web page C at times when the server is predicted to be overloaded. This prediction is based on the above assumption of a count of the number of users which are accessing pages that have transition links within them to web page C representing the actual demand for web page C. Figure 2 also describes an arrangement of sequential response to access requests by the web server.

Title: Uniaxial Tensile Strain in Semiconductor Devices
Inventor: WALLIS DAVID JOHN
IPC: H01L29/10
Filed: 2009-04-14
Abstract: A semiconductor device structure for example an n-FET or p-FET comprises an active layer 1 and a buffer layer 2. The active layer for example InSb is a quantum well structure. There is a lattice mismatch between the buffer layer which may be Alxln1-xSb and the active layer 1 which places the active layer under biaxial compressive strain. Uniaxial tensile strain is applied to the active layer to reduce compressive strain on the active layer in a second direction but not in a first direction. The tensile strain may be applied by stretching. This favours hole and electron mobility in the first direction and, renders the semiconductor device structure suitable for the formation of both p-channel and n-channel devices. A method of manufacturing a semiconductor device is also disclosed.

Abstract: 555,400. Piezo-electric crystals. STANDARD TELEPHONES & CABLES, Ltd. July 24, 1942, No. 10367. Convention date, July 25, 1941. Class 40 (v)] A rectangular piezo-electric crystal element is cut from a crystal of the Rochelle salt type so that its major surfaces are substantially perpendicular to one of the principal axes of the crystal and so that adjacent edges of the major surfaces are parallel to the other two principal axes, and comprises sets of independent electrodes for causing vibration in a plurality of independently controllable modes at frequencies depending on the dimensions of the major surfaces, one of the modes being the first shear face mode of vibration. Fig. 1 shows crystals 1, 1A cut with the principal plane at right-angles to the electric axis X of the natural crystal and with the major length dimensions L respectively parallel to the Z and Y axes respectively. Similar pairs of crystals are described having the major planes at right-angles to the Y and Z axes, Figs. 2 and 3 (not shown). With these orientations, the first and second face shear mode vibrations are substantially free from coupling to other modes and have a low temperature co-efficient of frequency. The provision of two electrodes on each major face enables the crystal to be driven simultaneously in the first and second face shear modes which may be used in the filter circuits described in Specifications 531,662 and 542,452. Specifications 532,925, 533,204, 553,457 and 554,788 also are referred to. The crystals may be mounted by suspension or clamping at the nodal points. The frequencies are determined by the ratio of width to length, and the impedance by the thickness.

Title: Improvements relating to the manufacture of glass fibres and rods
Inventor: GORDON JAMES EDWARD
IPC: C03B23/049
Filed: 1956-04-06
Abstract: 809,297. Strengthening glassware. T. I. (GROUP SERVICES) Ltd. April 5, 1957 [April 6, 1956], No. 10533/56. Class 56. Glass fibre or rod, is strengthened by subjecting its surface to mechanical compression at a temperature in the region of, but below, the normal annealing range and then allowing it to cool under that compression. The mechanical compression may be effected by repeatedly flexing the glass in all directions, or by subjecting it to alternating torsional force, or to sonic or ultrasonic vibrations. Another method, for producing glass fibre or rod, is to slip a glass tube over a rod or fibre of higher coefficient of thermal expansion, heating the composite bar above the softening temperature and then drawing it into a fibre; the different degrees of contraction on cooling put the outer surface under compression and so inhibit the formation of surface cracks.
