Filed: 2001-08-24
Abstract: A control system for executing an upshift from an off-going speed ratio to an on-coming speed ratio by controlling the release of the hydraulic pressure from the frictionally engaging element used for the off-going speed ratio and by controlling the supply of the hydraulic pressure to the frictionally engaging element used for the on-coming speed ratio comprises first and second off-going pressure releasing valves 70 and 80, which release the hydraulic pressure of the frictionally engaging element used for the off-going speed ratio, and a linear solenoid valve 60, which controls the operation of the off-going pressure releasing valves. The linear solenoid valve 60 controls the operation of the off-going pressure releasing valves in correspondence to the throttle opening of the engine. In this case, the smaller the throttle opening of the engine, the earlier the timing for releasing the hydraulic pressure from the frictionally engaging element used for the off-going speed ratio is set.

Title: Method for gasifying organic materials and mixtures of materials
Inventor: SCHMID CHRISTOPH
IPC: C10B53/02
Filed: 2000-09-22
Abstract: The aim of the invention is to provide a method for gasifying organic materials which is simple to carry out and requires minimal equipment and which produces an undiluted gas of high calorific value. The inventive method should eliminate the need to use fluid beds and heat exchangers with high temperatures on both sides, with the heat being transferred from the furnace to a heat-carrying medium in a particularly defined way. To this end, the feed material (101) is divided into a volatile phase and a solid carbon-containing residue in the pyrolysis reactor (104) by circulating a hot heat-carrying medium. After the reaction agent (109) has being added, said volatile phase is converted into the product gas by further heating in the reaction area (reformer) (107), also using the heat-carrying medium. The solid, carbon-containing residue is separated from the heat-carrying medium in the separating stage (121) and burnt in the furnace (105). The heat-carrying medium is heated by the waste gases of the furnace (105) in the heating area (117) and then returned to the reformer (107) and then the pyrolysis reactor (104).

Abstract: A transmitting section makes light, intensity-modulated by a modulating signal of a sine wave having a designated frequency, be incident on one end side of an optical fiber which is a measurement object. A feature value determining section converts the light, which exits from another end side of the optical fiber, into an electric signal, and finds, from the electric signal, a predetermined feature value of a signal component having a frequency equal to the frequency of the modulating signal. A computing section obtains a nonlinear refractive index of the optical fiber to be measured from the predetermined feature value by calculation corresponding to the predetermined feature value based on a nonlinear Schroedinger (Schrödinger) equation.
