A housing structure for projection type television receivers comprises a casing provided with an opening on each of the front side and the back side, a framework holding a screen and a back cover. The framework for holding the screen is installed on the front side of the casing. The back cover is installed on the back side of the casing. Concaved members for mating with bosses that are used to mount the framework are formed on the outer rim of the front side of the casing. Reinforcing ribs and guide ribs that are used to mount the back cover are formed on the back side of the casing. The housing structure disclosed here makes it possible to mount and detach the screen, working from the outside of the housing structure.

Molding methods for disposing a functional film on a hollow inner surface or undulated surface. A blow molding process for manufacturing a molded product having a hollow part and a pressure forming process for manufacturing a molded product having an undulated part, and the products produced there from. Before the parison or forming material is cooled and solidified, a compressed fluid containing a material for forming a film is supplied into a die, thereby forming a film simultaneously when molding.

Method of making a molded product having a functional film the product

A hollow structural component which includes an integral structure, partition walls intersecting each other within the integral structure, and a plurality of independent hollow portions formed as specified by the partition walls so as to be arranged within the integral structure. The integral structure is formed into one piece by one-shot molding or by one injection molding die which is caused to slide against each other between its stationary side and movable side for post-forming, whereby weight reduction of the hollow structural component, reduction in the amount of resin used, reduction in the number of parts involved, and improvement in the workability for assembling may be achieved with consequent cost reduction.

Hollow structural component

A method of manufacturing a functional hollow structural member having a structural member having a hollow part, and functional means disposed on the inside surface of the hollow part, comprising the steps of injecting a molding material into a molding die, injecting a gas and a functional substance into the molding material to form a hollow part in the molding material, forming functional means inside of the hollow part, and forming a structural member by solidifying the molding material. As the functional means, a layer having a magnetic function, conductive function, or antibacterial function is used.

Hollow structural member and method of manufacture

A vibration or shock absorbing member which is composed of a material capable of effecting injection molding such as plastics, rubber, ceramics, metallic powder mixed and kneaded with a specified binder, or glass powder mixed and kneaded with a specified binder, and includes an integral structure, a plurality of protrusions formed at least on one main flat surface of the integral structure, and a plurality of independent hollow portions provided symmetrically or in an aligned state within the integral structure through intersecting partition walls. Such integral structure is molded as one unit by one-shot molding (molding at one time) or by a single molding die for expanding the range of selection for materials and spring constants so as to achieve freedom in the choice of shapes and reduction in weight.
