An antenna for a receiver comprising a magnetic core in the form of a thin layer having a thickness less than 50 microns superposed on a casing of a receiver or on a block of components of the receiver, and a winding wound on said magnetic core and connected electrically to the components in the casing or in the block, the winding serving as the antenna for the receiver. A receiver which comprises said antenna.

A pneumatic tire comprises a tread-sidewall reinforcement extending between the tire sidewall portions through the tread portion which has a symmetrical cord arrangement to prevent ply steer. The tread-sidewall reinforcement is made of a series of loops of at least one reinforcing cord which loops spread over the circumference of the tire. The tread-sidewall reinforcement can be formed as a carcass or a reinforcing layer disposed outside a carcass. When viewed in the radial direction, the inclin...

A three-group zoom lens having lens groups, in order from the photographic object side, of negative, positive, and positive refractive power. The zoom lens is specially designed for use in a still or video camera employing a CCD array positioned at a fixed photographic image plane. Zooming is primarily performed by moving the two lens groups nearest the photographic object side, and focusing is primarily performed by adjusting the position of the lens group nearest the photographic image side. B...

A multichannel magnetic head is provided with two offset gap lines formed in the face of the core tips. Non-magnetic material insulates adjacent core tips, and cross-talk is reduced by an over-lapping core construction. Various length back cores are provided to minimize the head size; but reluctances are equalized by varying core material, core cross-sectional area, or the gap between the back and the tip cores.

A photoconductive glassy alloy containing selenium, antimony and an electric property controlling substance is used in a photoconductive layer of a photosensitive member for electrophotography comprising mainly three layers such as a support layer, a photoconductive layer and an insulating layer, or mainly four layers such as a conductive layer, an insulating layer, a photoconductive layer and an insulating layer.

A method of making a multi-channel magnetic head composed of a stack of a plurality of single-turn elementary heads. The method includes the step of defining a hollow for a conductive rod, which hollow extends through bore portions in core pieces and is open to each of a plurality of slots into which conductor plates are eventually placed to form with the conductive rod the single turns. The hollow is defined by the steps of inserting a hollow-defining rod of a heat resistant material into the b...

A high impact-resistant vinyl chloride polymer resin composition having an excellent weather resistance which is composed of from 3 to 30 weight parts of a modified MBS resin obtained from addition-reaction of an alkyl mercaptan containing from 2 to 20 carbon atoms with a butadiene-styrenemethyl methacrylate resin, and from 97 to 70 weight parts of a vinyl chloride resin.

A package comprising a pocket of a stiff material and a flexible bag secured within and to the edges of the pocket. The mouth of the pocket is expanded when the bag is supplied with the package material, to form a support and protective covering for the bag. The bottom of the pocket and the bag portion connected thereto can be removed from the remainder by separation along a destructible portion to provide a dispensing opening in the bag for removal of the contents.

An apparatus for continuously forming packages. Each package comprises a pocket and a flexible container therein with packaged material in the container. An endless tube of flexible material is formed from a continuous web at a tube forming station. Opposed areas of the tube are secured together in a sealing station to form a pouch with the opening of the pouch in the tube forming station. The pouch is supplied with a measured amount of packaging material and is moved through the sealing station...

A method of making a multi-channel magnetic head. A support plate having a flat surface is provided, and a magnetic core having a winding wound thereon is placed on said flat surface of said support plate in order to make an elementary unit. A plurality of said elementary units is stacked on one another, and said stacked elementary units are adhered to each other. The stack is cut into two halves in at least one plane which is perpendicular to the flat surfaces of said support plates and which d...
