Abstract: A butterfly valve seat structure has a polymeric sealing head (8) slidably supported on the radially inner portion (12) of a flat metal washer (9) so as to be capable of radial sliding movement on the washer (9), a radially outer portion (10) of the washer being rigidly clamped between the valve housing (1) and the seat retaining ring (6), and a radially intermediate portion (11) of the washer is capable of axial movement relative to the axis of the valve passage to facilitate axial movement of the sealing head (8). Axial projections (27, 28) on the head (8) serve to resist any tendency to blow-­out of the sealing head. The combined abilities of the sealing head to move axially and radially help to provide a good sealing action against the valve disc (3).

Title: Servo control method by the disturbance estimation observer
Inventor: TORII NOBUTOSHI ROOM FUYOHAITS
IPC: G05B13/02
Filed: 1990-01-17
Abstract: A servo control method which, even in the case of a machine having a large variation in inertia, makes it possible to properly estimate and remove disturbance by the disturbance estimation observer so that the machine exhibits improved immunity against disturbance. An estimated disturbance (x) is found based on the actual instruction (I-y') and the actual motor speed (v) by a disturbance estimation observer(5) equipped with four transfer elements (51 to 54) that have transfer functions (Kt/Jm,K1,K2/S,1/S)determined by values corresponding to torque constant(Kt), inertia(Jm) and parameters(K1, K2). The gain is adjusted by the transfer element(3) and high-frequency components are removed by the filter (4), whereby a corrected estimation disturbance (y') is found. A servo motor is driven by the actual instruction current obtained by subtracting a corrected estimation disturbance from the instruction current (I), so that the effect of disturbance is removed. The parameter (jm) of transfer functions (3,51) is variably set depending upon a change in the inertia of the machine that stems from a change in the operation condition of the machine, and disturbance is properly estimated and is removed even when the inertia varies to a greater extent.

Title: Packaging envelope for meat.
Inventor: MEIXNER HANS W
IPC: A23L13/00
Filed: 1990-03-10
Abstract: Packaging envelope or packaging bag consisting of at least two plies, of which the one ply is elastic and the other ply is a gas-barrier layer. The inner ply can consist of a food-compatible material, so that foods, in particular meat, can be placed in the packaging envelope or the packaging bag. For packaging, the envelope is expanded and the object then inserted. After the insertion, the envelope contracts through its flexibility in the direction of the center line of the envelope and automatically presses the air present between object and envelope out of the packaging. In the packaging of shapable objects, in particular meat, the envelope presses these objects, in particular the meat, simultaneously into an at least approximately circular cross-sectional shape through the exerted radial forces. The gas-barrier layer prevents the entry of air through the envelope material even for a lengthy storage period.

Abstract: A semiconductor integrated circuit device is disclosed having first and second conducting layers (110, 120), with the first layer having a shape which enhances field emission tunneling off of the surface thereof.

Abstract: Compositions and methods of manufacture for producing a medicament composition capable of absorption through the mucosal tissues of the mouth, pharynx, and esophagus. The present invention relates to such compositions and methods which are useful in administering lipophilic and nonlipophilic drugs in a dose-to-effect manner such that sufficient drug is administered to produce precisely a desired effect. The invention also relates to manufacturing techniques that enable therapeutic agents to be incorporated into nondissolvable drug containment matrixes which are capable of releasing the drug within a patient's mouth. An appliance or holder is preferably attached to the drug containment matrix. Employing the present invention the drug may be introduced into the patient's bloodstream almost as fast as through injection, and much faster than using the oral administration route, while avoiding the negative aspects of both of these methods. The nondissolvable drug containment matrix may include permeation enhancers to increase the drug absorption by the mucosal tissues of the mouth. The matrix composition may also include pH buffering agents to modify the saliva pH thereby increasing the absorption of the drug through the mucosal tissues.
