摘要:
A head of a sewing machine mounted on a table of the sewing machine can be turned at the rear portion thereof. A belt device is provided at the side of the head for delivering a rotary motion of a driving device to the head. A guard member is fixed to the table for covering a rear portion of a belt of the belt device which is exposed on the table. The guard member has an inclined wall upper portion provided with a notched recess for receiving the belt 7 when the head is turned rearwardly. A cover member is openable and slidable over the notched recess. The cover member is urged by a spring in a direction to be closed.
摘要:
A method for manufacturing cigarette filters which have a well-stabilized shape in which acetate fibrous tows impregnated with carboxylic acid ester of polyol are formed into a predetermined shape, uniformly impregnated with water, and irradiated with microwave energy. Water is used during the application of microwave energy to enhance the absorption of microwave energy and hence heating of the filter. This causes the carboxylic acid ester of polyol to very rapidly disperse causing it to permeate into the acetate fiber to rapidly complete the stabilization and solidification of the filter.

Provided are novel ligands for transition metal complexes which exhibit high coordination power with respect to metals by being free of substituents at the positions ortho to phosphorus or arsenic and which have electron-withdrawing power comparable to the highest level known in conventional ligands. One ligand includes a compound represented by General Formula (1): R1R2R3A or General Formula (2): R1R2A-Y-AR3R4 and having a total of 15 to 110 carbon atoms. In the formulae, A is phosphorus or arsenic; R1, R2, R3 and R4 are each independently a substituted pyridyl group having optionally different electron-withdrawing groups bonded to the positions meta to the atom A as well as hydrogen atoms bonded to the positions ortho to the atom A; and Y is a divalent group derived from a C2-20, optionally substituted and optionally heteroatom-containing, aliphatic, alicyclic or aromatic compound or from ferrocene.

A shape measuring apparatus that measures a three-dimensional shape of a measuring target has a lighting device that irradiates the measuring target placed on a stage with light, an imaging device that takes an image of the measuring target, a shape calculating device that calculates orientations of normals at a plurality of points on a surface of the measuring target from an image, the image being obtained by performing imaging with the imaging device while the lighting device irradiates the measuring target with the light, the shape calculating device calculating the three-dimensional shape of the surface of the measuring target from the calculation result of the orientations of the normals, a ranging device that measures a distance from a predetermined reference position with respect to at least one point on the surface of the measuring target, and a determination device that determines a spatial position of the three-dimensional shape of the surface of the measuring target, the three-dimensional shape being obtained by the shape calculating device using information on the distance obtained by the ranging device.
摘要:
This invention is directed to correcting a smear by a line-sequential reading scanner. To accomplish this, in a line-sequential reading type image reading apparatus (scanner), the first memory stores reference smear amount data of a smear occurred for each color component. The correction amount for the brightness value of each color component obtained by reading an original by an image sensor is calculated based on the reference smear amount data stored in the first memory and the brightness value level of a pixel on a preceding line. The brightness value is corrected based on the correction amount.
