Title: Method for calibrating a manufacturing process model.
Inventor: TSAI KUEN-YU
IPC: G03F7/20
Filed: 2012-08-21
Abstract: Calibration of models for manufacturing processes that are subject to circuit layout proximity effects is performed, including optical proximity correction (OPC) model calibration. A target structure is produced using a layout and a manufacturing process. The target structure is illuminated and an electromagnetic scattering property is detected. A manufacturing process model for simulation of the manufacturing process is produced, which comprises at least one manufacturing process parameter determining a model electromagnetic scattering property using the manufacturing process model and the layout. The model electromagnetic scattering property is compared to the detected electromagnetic scattering property and based on the result of the comparison, calibrated manufacturing process parameters are output for calibrating the manufacturing process model. The determining and the layout may include determining structural information corresponding to the target structure using the manufacturing process model and determining the model electromagnetic scattering property using the structural information.

Title: Method for spatially positioning crack in t-joint weldment
Inventor: DUANHU SHI
IPC: G01N23/203
Filed: 2020-01-17
Abstract: The present invention disclosures a method for spatially positioning a crack in a T-joint weldment, which belongs to the technical field of weldment detection. In the method, firstly, the T-joint weldment is rotated left and right to obtain the left and right rotation images by the X-ray detection. According to the geometric relationship between the parts of the detected image, the mathematical model for calculating the depth and the offset of the crack defect in the T-joint weldment is established. According to the above model, the depths h₁, h₂ and the offsets x₁, x₂ of the two ends of the crack tip, the offset x of the middle point of the crack and the inclination angle θ of the crack in the T-joint weldment are determined respectively. The distribution of the crack defect along the length direction of the welding line can be obtained by image processing, thereby realizing the spatial positioning of the crack defect in the T-joint weldment.

Title: Annular kiln for batchwise firing bricks - which can be loaded mechanically and is operated discontinuously
IPC: F27B13/04
Filed: 1974-02-22
Abstract: An annular kiln with firing and hardening chambers is made without a curved firing space at one end. The parallel straight chambers left can be closed off and the other curved portion is divided by a wall. The chambers can be filled using lift trucks. The heat released during cooling can be used to dry unfired matl. By this means the extra heat needed for the batch process can be recovered almost completely. A reducing atmosphere can be used in one zone without affecting the rest of the kiln.

Title: Appts. for mechanically salting fresh pickled cheese - has pneumatically operated head on movable carriage with suction ports and brine injection needles
IPC: A23C19/064
Filed: 1977-12-14
Abstract: Pickles cheese is salted and packed by means of a device mouned on a rail track equipped with a vertically moving piston to which two chambers are attached, one for drawing and maintaining a vacuum, and the other for feeding salt solution into the cheese. The vacuum chamber is connected to a series of vacuum heads with suction ports which are placed in contact with the cheese and hold the head firmly against it. The ports are also equipped with valves so thaT, in the event that the surface of the cheese does not permit one of the heads to bed down, the valve closes and the vacuum in the chamber can still be maintained. The salt solution chamber is coupled to needles which pass through the vacuum chamber and ports although isolated from them and are injected into the cheese as the head is lowered. The needles have drainage ports which distribute the injected brine into the cheese. The injection needles are pref. 7-9 cms long with an internal diameter of 0.4-0.8m. The device enables the salting of the brine to be incorporated into a packing line with a saving of labour and space.

Title: Coil unit of coreless type armature - has inner and outer cylindrical coils with wires at end surfaces aligned in radial direction
IPC: H02K3/04
Filed: 1980-10-31
Abstract: The coil unit includes inner (11) and outer (12) cylindrical coils, each comprising coil wires (1) equal in length and disposed in parallel. The coils (11,12) are fitted together and then combined in such a manner that respective coil wires at the end surfaces of each cylinder align with each other in the radial direction.

This construction provides a coil unit of a uniform thickness radially of the coil unit, as well as uniform coil wire length per turn. The result is a coil unit having excellent dynamic balance. Moreover, designing a motor having different numbers of turns is facilitated since a suitable cross-sectional profile for the coil wires can be adopted while the cross-sectional area is held constant.
