A device (1) for transferring a pattern (12) from a stamp (10) to a substrate (20) comprising a table (22) supporting the substrate (20), a flexible stamp (10) and a movably arranged body (25), the body (25) has a pressure chamber (27) that applies pressure to a part of the stamp (10), thereby pushing this part towards the substrate (20) and into contact with the substrate (20). During pattern transfer, the body (25) is moved. As a result, adjacent parts of the stamp (10) are continuously pushed towards the substrate (20), contacting the substrate (20) and moved back into position again. In this way, the transfer of the pattern (12) of the stamp (10) to the substrate (20) is achieved without causing vibrations, thereby achieving the transfer of the pattern (12) in a high-precision manner.

The invention relates to a non-contact matrix switch which is used for controlling a plurality of lighting devices. The switch comprises a micro-controller which is used for realizing core control, an operation panel with a plurality of operational keys, and a matrix output module of N non-contact switch elements. The N non-contact switch elements are divided into two groups. One group has K non-contact switch elements, the other group has L non-contact switch elements, wherein, N is equal to K+L, and K, L are the integral numbers which are greater than 1. The micro-controller controls the output of each switch element through the input information of the operation panel, thus realizing the control of the switches of K*L lighting devices. The invention can be used in the places where a large quantity of lighting devices are needed, and has the advantages of simple construction, low cost and convenient control.

The invention discloses a method for extracting and expressing assembly connection relationship information for assembly sequence planning, using conventional methods to generate assembly contact matrix, assembly support matrix and assembly interference matrix of products; by analyzing different types of connectors, the relationship between parts can be obtained The connection relationship and the database of parts stored in the sequence of installation and assembly, the connection relationship is introduced into the assembly contact matrix to form the assembly contact-connection matrix; the reference parts and candidate parts are determined through the assembly matrix, and the candidate parts are processed and the parts to be assembled are set , determine the components to be assembled that can be assembled, and then match them with the database to obtain the assembly sequence of all parts in the components to be assembled. The invention obtains the connection relationship between the parts by classifying and analyzing the connectors and acts on the assembly sequence planning, which can improve the efficiency of the assembly sequence planning, reduce the assembly cost, reduce the error rate, and shorten the production cycle.

The present invention relates to a data collection method of a multi-contact matrix touch sensor, the sensor includes a matrix network of units, the method comprises the following steps: sequentially scanning (S32-S37, S41, S42) the units of the matrix network; measuring ( S38) electrical characteristic at each unit place, described electrical characteristic represents the weight (IRC) of each unit; Said weight (IRC) is compared with predetermined one or more effective values ​​(S39); When said weight When within the interval of valid values, record (S43) the data associated with the unit; check (S44) the existence of data records associated with at least one adjacent unit; and if at least Data associated with an adjacent cell has already been recorded, then the existing envelope is updated (S45) by recording the data associated with the cell in the existing envelope. The invention can be used especially in touch screens.

The invention relates to the technical field of electrical equipment, in particular to a moving contact base body and a three-position isolating grounding switch. The base body of the moving contact is a slender tubular structure, and there are two long holes arranged opposite to each other on the tube wall. The extending direction of the long holes is consistent with the length direction of the moving contact base body. The guide surface is used to guide the contact finger installed on the contact seat to slide over to make the contact finger smoothly compressed. The guide surface includes a side guide surface connected to the side wall of the long hole and an end connected to the end wall of the long hole. When the moving contact base moves relative to the moving contact base and the contact finger passes through the end of the long hole, the guiding surface can guide the finger to slide through the end of the long hole, and the end guiding surface and the side guiding face The compression of the contact finger has a guiding effect, which can realize the smooth compression of the contact finger. The above-mentioned moving contact base is used in the three-position isolation grounding switch, which can improve the reliability of the conductive contact between the moving contact and the moving contact seat during the relative sliding process. and stability.

A shielded semiconductor chip carrier having a high-density external interface includes conventional printed circuit boards having plated through holes for achieving shielding of the contacts of the matrix. Two fork type connectors have molded about the distal ends thereof an annular ring of dielectric plastic material, and fork type connectors are press fit into each plated through hole, thereby locking the electrical contact within the shield formed by the plated through hole. The resulting connector provides a high-density contact matrix with each connector being electrically shielded along substantially its entire length.

A portion of a reinforcing member has a stacked structure 102 in which plural iron plates having openings 106 are stacked. A hollow portion 107 is formed inside the stacked structure 102, so that the reinforcing member is reduced in weight. Porous bodies 103 composed of non-woven fabric of metal fibers are disposed on surfaces contacting matrixes, so that adhesion between the reinforcing member and the matrix is improved, and peeling therebetween is prevented. A cast product which is composed of light metal and has the above reinforcing member has a small thermal expansion. For example, the cast product is desirable for use for a journal portion of an engine block.
