Title: Fluorinated polyimide resin composition
Inventor: SHIBA SHOJI
IPC: C08K5/17
Filed: 1991-04-12
Abstract: PURPOSE:To prepare the title compsn. which gives a film prevented from suffering thickness decrease and improved in solvent resistance by dissolving a fluorinated polyimide resin having specific structural units and a diamine compd. in an org. solvent. CONSTITUTION:The title compsn. is prepd. by dissolving a fluorinated polyimide resin having structural units of the formula and a diamine compd. [e.g. 2,2-bis(4- aminophenyl)hexafluoropropane] in an org. solvent. The resin is prepd. by conducting the cyclodehydration and epoxidation in the solvent since the resin is sol. in the solvent. When applied to a substrate plate and heated, the compsn. cures by intermolecular cross-linking, thus forming a film prevented from suffering thickness decrease. The compsn. also can form an insulating interlayer film excellent in solvent resistance.

IPC: H01L21/30
Filed: 1993-04-07
Abstract: PURPOSE:To allow correct calculation-of the amount of positional shift even if the measuring position of an alignment mark is shifted by one half or more of the grating width by subjecting the positional shift detection error of the alignment mark in the form of a diffraction grating, to be measured through interference with a reference grating, to correction corresponding to the grating width. CONSTITUTION:A positional shift detection error occurring when the shift of an alignment mark 5, comprising a diffraction grating formed on a water 4, is measured through interference with a reference grating 2 is eliminated by performing correction corresponding to the grating width (d). Detector output values DELTAx' corresponding to a plurality of alignment marks 5 on the wafer 4 are preserved, for example, and a decision is made that the mark 5 is shifted by one half of the grating width (d) or more based on the detector output value DELTAx'. When the mark 5 is shifted by one half of the grating width (d) or more, a value (n) is predicted for the detector output value DELTAx' thereof and the grating width (d) is corrected by an amount (nd) thus eliminating the positional shift detection error.

IPC: F02D45/00
Filed: 1995-04-05
Abstract: PURPOSE: To assuredly control air-fuel ratio by correcting predicted filling air amount not only by valve opening/closing timing, but also by intake air amount. CONSTITUTION: Intake air amount detected by an airflow meter 107 is compensated by an internal combustion engine speed and a throttle valve opening, so that filling air amount in a combustion chamber 104 when engine valves 102, 103 are closed, is predicted. This predicted filling air amount is compensated to be larger if valve overlap amount adjusted by a VVT 114 is large and to be smaller if intake air amount is large, so that the predicted accuracy of the filling air amount can be improved even when a VVT function is equipped with this device. Further, fuel injection amount is determined on the basis of this compensated filling air amount, so that fuel injection amount can be also assuredly determined.

Title: Flow control valve
Inventor: MIZUNO KYOSUKE
IPC: F16K31/02
Filed: 1989-03-31
Abstract: PURPOSE:To facilitate remove operation for moving a valve body by furnishing a resilient member which energizes opening/closing to either of them, and providing a current supply responsive deforming member, which deforms when current is supplied and which moves the valve body continuously against the energization. CONSTITUTION:If a current supply responsive deforming member 15 is in dead condition, a valve body 8 is moved down by a spring 17 to shut a variable throttle 9, and the area of communication between two ports 5A, 5B is minimized. When rectangular pulses from an operational circuit 16 are supplied to this member 15, it is heated in accordance with the duty ratio of the rectangular pulse and deformed to assume a coil, that causes shortening of its length to raise a shaft 13, which moves the valve body 8 in the direction of opening. As a result the degree of opening of a throttle 9 is increased to enlarge the area of communication between the two ports 5A, 5B. With a control valve 1 in this constitution the degree of opening of the throttle 9 can be adjusted only by controlling the amount of current supply to the deforming member 15, that should facilitate remote operation.
