Insulation displacement type contacts (3) each having a receptacle portion (9) are individually held in compartments (4) that are formed in an insulated housing (2). A stationary die (21) temporarily holds an electric connector (1) having such contacts (3). A punch (22) facing and cooperating with this die (21) will reciprocate vertically to press wire ends (15) into the receptacle portions (9) so as to establish electric connection between each wire end (15) and each portion (9). In order to protect these portions (9) from being forcibly widened when an insulation displacement operation is done, a pair of upright guards (31,32) formed integral with a supporting plate (33) are disposed in the die (21). These guards (31,32) are spaced from one another a distance equal to the sideways width of the insulated housing (2), so that its end walls (6,6) are propped up by these guards from the outside. Thus, a means is provided to protect the receptacle portions (9) from being widened, at the same time enabling this apparatus to be composed from simple and cheap parts easy to replace with each other.

The present invention relates to a panel-shaped molded product having a laminated structure which is produced from a resin and used for side doors, back doors, hoods, roofs, etc., and exhibits a more excellent finishing accuracy without occurrence of bleed-out along an inner periphery of a frame part and fine distortions on a design part. The panel-shaped molded product of the present invention is a molded product having a laminated structure which is obtained by injection-molding the frame part (2) on one surface of the plate-shaped design part (1) wherein an inner peripheral portion (4) of the frame part (2) is closely attached to the design part, and has a thickness changing region where a thickness of the frame part is reduced toward the side of a center of the frame part such that a ratio between a width of the thickness changing region and the thickness of the frame part (2), and a ratio between a width of the thickness changing region and a width of the frame part (2) are respectively adjusted to satisfy specific relationships.
摘要:
An apparatus for introducing a pressurized gas includes a pressurized-gas supply-source, a plurality of measuring tanks, a first pressurized-gas supply-line, pressurized-gas supply valves in the first pressurized-gas supply-line, second pressurized-gas supply-lines and pressurized-gas discharge-control valves disposed in the second pressurized-gas supply-lines. A combination of the measuring tanks is determined on the basis of the amount of a pressurized gas required for forming a hollow portion in a molded article, and the pressurized-gas discharge-control valves disposed in the second pressurized-gas supply-lines are controlled on the basis of the above determination.
摘要:
An injection-molding apparatus comprises a mold assembly having a first-molten-resin injection portion for injecting a first molten thermoplastic resin into a cavity of the mold assembly, a second-molten-resin injection portion for injecting a second molten thermoplastic resin into the cavity, and a pressurized-fluid introducing portion for introducing a pressurized fluid into the second molten thermoplastic resin injected into the cavity. The injection-molding apparatus also comprises a first injection cylinder communicating with the first-molten-resin injection portion, and a second injection cylinder communicating with the second-molten-resin injection portion.
摘要:
A method of coding and transmitting moving pictures includes the steps of coding an extended background image, coding parameters indicative of an image area within the extended background image, coding a foreground picture that is to be composed with a background picture corresponding to the image area indicated by the parameters, coding a defocus value indicative of an extent to which the background picture should blur, and transmitting the coded extended background image, the coded parameters, the coded foreground picture, and the coded defocus value as a data stream to a decoder side. Coding and transmitting of the defocus value makes it possible to defocus the background picture at the decoder end, thereby producing a composed image of the background picture and the foreground picture having natural appearance.
