Title: Method for forming thermoforming sheet
Inventor: ISHII MASAHIRO
IPC: B29C51/14
Filed: 1990-04-11
Abstract: PURPOSE:To enhance the formability and surface properties of a thermoforming sheet by a method wherein the surface temperature of a thermoplastic resin layer containing the specific amount of a reinforcing fiber is increased by a specific degree over the surface temperature of a thermoplastic resin layer containing no reinforcing fiber to form the thermoforming sheet under heating. CONSTITUTION:Any kind of resin that is softened and melted under heating can be used as a thermoplastic resin and, for example, a polyethylene resin, a polypropylene resin and the like are used as the same. Fibers that are thermally stable at the melting temperature of a powdered thermoplastic resin to be used can be used as reinforcing fiber, and examples of the same include inorganic fibers such as glass fiber and carbon fiber and organic fibers such as aramid fiber and polyester fiber. Since a thermoforming sheet 25 consisting of two layers of a thermoplastic resin layer containing 5-70wt.% of reinforcing fiber 1 and a thermoplastic resin layer containing no reinforcing fiber is formed, surface properties are improved and, furthermore, the surface temperature of the layer containing the reinforcing fiber is increased by at least 5 deg.C over the surface temperature of the other layer containing no reinforc ing fiber to thermoform the sheet. Therefore, the thermoforming sheet 25 is easily formed, and the resultant sheet has good surface properties without having recesses and protrusions caused by a glass fiber and the like.

Title: Air-fuel ratio control system and method
Inventor: KERNS JAMES MICHAEL
IPC: F02D41/00
Filed: 1999-04-05
Abstract: PROBLEM TO BE SOLVED: To purge fuel vapor from a fuel system to an engine suction part while fuel error is learned and analyzed to estimate the purge amount by reflecting a difference between a target air fuel ratio and a measured exhaust air fuel ratio in the fuel supply error and an estimated purge flow at the same time, and suitably distributing the same to both of them. SOLUTION: A fuel supply system of an internal combustion engine of an automobile is controlled by a control device. In the executed routine, a fuel error term is calculated from a difference between an air fuel ratio and a target air fuel ratio measured by a universal exhaust oxygen sensor, and multiplied by a suction mass air quantity (step 310). Secondly, a fuel error model is used for estimating a fuel flow error, and a purge model is used for estimating a purge flow entering an engine (step 312, 314). The other remaining error is calculated and used for updating the fuel error model and the purge model (step 316, 318). Over the whole of the operating condition of the engine, a fuel error and a purge flow are continuously estimated and updated.

Title: Apparatus for detecting opening of throttle valve
Inventor: TAKAHASHI SHIYUNJI
IPC: F02D9/02
Filed: 1984-05-16
Abstract: PURPOSE:To control the quantity of intake air accurately, returning a throttle valve once to the completely closed position by means of an actuator in case that some trouble is caused with a zero-point switch of a throttle sensor, and executing control of air quantity by considering the position where the throttle valve is stopped as a zero point in a ''soft'' manner. CONSTITUTION:The quantity of intake air is controlled by detecting the opening of a throttle valve by means of a throttle sensor having a full-opening throttle switch (zero-point switch). At a step 30, judgement is made whether some trouble is caused with the zero-point switch or not. In case of NO, the program proceeds to a step 31, where the output of the zero-point switch is picked up. Further, at a step 32, the quantity of intake air is controlled in an ordinary manner. In case that the above judgement is YES, on the other hand, the program proceeds to a step 33, where the throttle valve is returned once to the completely closed position by means of an actuator. Then, the program proceeds to a step 34, and the position where the throttle valve is stopped by the zero- point switch is considered as a zero point in a ''soft'' manner. Subsequently, control of the air quantity is processed at the step 32.
