By grounding a metal first housing, radiation noise generated from the coupling circuit is shielded. Further, by enclosing the first housing in a metal second housing in a manner such that the first housing and the second housing do not come into contact with each other, and grounding the second housing by connecting the second housing to an engine block, radiation noise generated by the capacitive component between the coupling circuit and the first housing is shielded by the second housing. As a result, the influence of this noise on peripheral devices of the high frequency discharge ignition device can be suppressed.

High frequency discharge ignition device

A problem exists in that, as a loop through which high frequency energy conducts is long, it is difficult to suppress noise generated from the loop and suppress an influence thereof on peripheral equipment. A high frequency discharge ignition device according to this invention is a structure integrally constituted by a second housing into which a high frequency energy supply circuit is built and a first housing into which an output circuit is built, wherein the high frequency energy supply circuit is connected to the output circuit by a connection terminal so as to be connected to a spark plug which is mounted on a grounded object. Further, the high frequency energy supply circuit is grounded via a conducting member disposed in a through hole provided in the first housing.

In order to transmit high frequency energy to a coupling circuit, if the high frequency energy is transmitted via a harness provided with a high-voltage cable, the loop in which the high frequency energy is conducted is long, and thus, noise occurring from the loop is increased. Thus, shielding is needed to be provided to the entire apparatus. The present invention has a structure in which: a high frequency energy supply circuit and a coupling circuit are connected by a connection member; and a housing having therein the high frequency energy supply circuit is integrated with a housing having therein the coupling circuit. Accordingly, the entire apparatus can be downsized and noise occurring from the loop can be reduced.

High frequency discharge ignition apparatus

The objects of this invention are to set a predetermined height position for the portion of parison or preform that is the first to come in contact with body molding planes of a split mold and to prevent air from being trapped between in-mold labels and the container which is blow molded from the parison or the preform. In-mold labels are fixed to the entire outer surface of body of main container. An annular thinnest wall portion is formed in the wall of the body so that the thinnest wall portion is the first to come in contact with the body molding planes of a split mold. Under this construction, no bulge of air is formed between the body and the in-mold labels fixed to the entire surface of the body.

In-mold labeled container and molding process thereof

An object of the present invention is to provide a shield case capable of applying shield to a connection portion by means of various versatile connectors. A configuration is made such that the shield case includes a lower case () to be mounted on a housing () of an electronic control device and an upper case () to be fitted into the lower case () with a harness () having a female connector () being nipped. In the shield case, the lower case () and the upper case () are fastened to the housing () by screws () with a shield conductor () of the harness () being nipped between the lower case () and the upper case ().

Shield case

A method for applying a label, and a label for in-mold molding which comprises a printed layer formed on a surface of a non-oriented plastic base film over which a membrane layer for bonding to be welded by the heat of molded article at the time of the in-mold molding is overlapped. The label is inserted into a mold for the in-mold molding, the label is held on the proper position in the mold by vacuum suction, or by static electricity, and a moldable article, such as a container, is molded by injecting, filling the plastics into the mold or by expanding a parison which was placed in the mold.
