摘要:
A method and apparatus for forming a hollow glass article comprises delivering a gob of glass to a blank mold (30), providing a first neck ring (A) to a position adjacent the blank mold (30), forming the gob in the blank mold into a parison (P), moving the first neck ring (A) to transfer the parison to a blow mold (31), blowing the parison (P) in the blow mold to a hollow article, releasing the engagement of the first ring (A) with the hollow article, moving the first neck ring (A) away from the blow mold (31), removing the hollow article from the blow mold (31), returning the first neck ring (A) to a position adjacent the blank mold (30) to repeat the cycle, providing a second neck ring (B) adjacent the blank mold (30) while the first ring (A) is moving toward the blow mold (31), delivering a second gob of glass to the blank mold (30) while the second ring (B) is in position adjacent the blank mold, forming the second gob into a second parison, moving the second parison to a position adjacent the blow mold (31) while the first neck ring (A) is being returned to a position adjacent said blank mold (30); and controlling the positioning and movement of the first neck ring (A) and second ring (B) independently of one another such that the velocity and movement of each neck ring is varied without affecting the overall forming cycle.
摘要:
Flat panel image sensor (10) is provided by combining photoconductive imaging electrodes of a vidicon with a two-dimensional array of cold cathode field emitters (14) commonly used for flat panel field emission display (FED) systems. The FED operates normally to emit electrons which are accelerated in prior art displays towards a luminescent phosphor to generate light output proportional to the cathode emission. Rather than accelerating towards a phosphor, electrons are accelerated towards a photoconductor layer (16) to replace charge removed from the layer by an incident radiation pattern directed at the photoconductor layer (16) through a layer of transparent, electrically-conducting material (17) which serves as a radiation window. The transparent, electrically-conducting layer (17) may be partitioned to reduce stray capacitance for large area sensors and the partitioned, electrically-conducting layer (17) permits a parallel readout mode of operation.

An electrical connector (14) includes an elongated dielectric housing (16) having an elongated slot (18) disposed generally along a longitudinal axis (20) of the housing for receiving, edgewise, a printed circuit board. A plurality of terminals (28) are inserted through a bottom terminating face (16b) of the housing into a plurality of passages (22) along at least one side of the slot. Each terminal (28) includes a retention portion (36) press-fit in a retention section (30) of a respective passage. The retention section includes inner side walls (30b) and an outer side wall (30c) which guides, locates and supports the retention portion (36) and, thereby, the terminal (28) within its respective passage (22). The retention area of the outer side wall (30c) is substantially greater than the retention area of the inner side walls (30b).
摘要:
A method and apparatus for compression molding plastic articles including closures which includes providing co-acting sets of tools (27, 28) including a first set (27) of moving a core (41) and core sleeve (42) into engagement with a cavity mold (51) on a second set (28) of tooling. An actuator (34) is provided between the first set of tooling (27) and a fixed upper cam (29). The second set of tooling (28) includes an associated actuator (52) supporting the cavity mold and associated with a lower fixed cam (31). A nitrogen cylinder (39) in the second set of tooling (28) provides for control of the compression molding force. In a preferred form, a plurality of sets of tooling are provided in circumferentially spaced relation on a rotating turret (22) supported by a central column (21). A common manifold supplies the pressure at accurately controlled pressure to each of the nitrogen cylinders (39). A control system is provided for monitoring and changing the pressure.
摘要:
An electrical terminal (10) is adapted for use with an electrical conductor (16). The terminal has a terminating portion (22) with a generally U-shaped cross-section having a web (32) and a pair of sidewalls (34) extending from two opposite longitudinal edges of the web. The sidewalls are generally trapezoidally shaped with relatively wide bases (34a), joined to the longitudinal edges of the web, and relatively narrow tips (34b). The bases (34a) are transversely aligned across the web (32). The tips (34b) are offset across the web (32) so that the tips are spaced longitudinally of the web. Therefore, the tips (34b) will bypass each other when crimped toward each other to terminate the electrical conductor (16), all within the longitudinal confines of the bases (34a) of the sidewalls (34).

摘要:
A method of making a capacitive coupling device, especially in a transistor of an EEPROM, and such device. The interpoly dielectric layer (66) between control gate (68) and floating gate (64) consists of a thin layer of oxide and a layer of tantalum pentoxide so as to obtain a high capacitance value with a small physical size. This allows EEPROM cells which require substantially lower programming and erasing voltages.
摘要:
A vane-type rotary hydraulic machine that comprises a housing (12), a rotor (40) mounted within the housing and having a plurality of radially extending peripheral slots (42), and a plurality of vanes (44) individually slidably mounted in the rotor slots. A cam ring (32) within the housing surrounds the rotor and has a radially inwardly directed surface (46) forming a track for sliding engagement with the vanes. Symmetrical diametrically opposed fluid pressure cavities (48) are formed between the cam ring surface and the rotor, and fluid inlet (58) and outlet (68) passages in the housing are coupled to the fluid pressure cavities. Both of the fluid inlet and outlet passages comprise housing fluid passages (60, 62) that open to side faces of the rotor radially inwardly of the fluid pressure cavities, and fluid passages (54, 56) extending radially through the rotor between outer ends opening at the periphery of the rotor between adjacent slots and an inner end opening axially at the side faces of the rotor for communication with the housing fluid passage as a function of rotation of the rotor.
