Patent EP-0262480-B1 (EP)
IPC: H03F3/345
Filed: 1987-09-09
Granted: 1991-08-07
Abstract: A current mirror circuit assembly includes a first current mirror circuit formed of an input transistor connected as a diode and a mirror transistor. The input transistor and the mirror transistor have gate terminals connected to one another and output circuits with output terminals. One of the output terminals of each of the input transistor and the mirror transistor are connected to a supply potential. A regulating transistor has an output circuit connected in series with the output circuit of the mirror transistor. A second current mirror circuit is formed of transistors with output circuits. Other transistors are controlled by the other of the output terminals of a respective one of the input transistor and the mirror transistor. One of the other transistors is fed back to the regulating transistor and the other transistors are connected to the output circuits of the transistors of the second current mirror circuit.

Abstract: This invention relates to an improved valve pin bushing (42) for a multi-cavity injection molding system. The valve pin bushing has a central bore through which the valve pin (60) extends. The melt duct (120) extends through the bushing (42) to join an enlarged portion (66) of the central bore around the valve pin (60). In the bushing according to the invention, the melt duct (120) branches into two arms (128, 130) with smoothly curved bends which lead to opposite sides of the valve pin (60). This avoids the problem of streaking and slow melt flow on the opposite side of the valve pin.

Abstract: Air is extracted by a collection zone (3) (fig. 3) through duct (8) and four holes (7) from chamber (4) located between the wearer's head and the polystyrene; the resulting low pressure that is created pulls other air through openings (5) at the sides of the front; the entry of the air by such openings is aided by the fact that a slight pressure is present inside the helmet in the front zone by dynamic effects, and this entry generates a true and real circulation that, preventing stagnation of the hot air, creates a real inside conditioning effect. Further the air, which enters by the lower part of the helmet and by the openings to eliminate the condensation on the visor, is sucked upward by chimney effect which also contributes to reducing the steaming of the visor itself.

Abstract: An autombile radio capable of receiving VHF entertainment programs from a station in which traffic information signals are modulated in a 57 kHz subcarrier is equipped with two decoders for the 57 kHz subcarrier signals, one decoder for traffic information signals modulated in an analog fashion on the subcarrier and another decoder for digital signals modulated on that subcarrier by double-sideband suppressed-carrier modulation. The first decoder is for a system already in use in which traffic information, at least if urgent, is intended to override the entertainment program, and the receivier has the usual circuits for that override. The second decoder is for a system that is planned but not yet in use in which the received digital signals can call out one or more standard messages or message portions from a read-only memory and either the memory addresses or the memory outputs are storable. They are made audible by speech synthesizer and, because they are stored at least until the next message comes in, can be recalled if the user wishes. The receiver switch for turning on the traffic information feature is a selector switch with positions selecting either type of decoder and, in a modification designed for where both systems are available, the corresponding switching system gives priority to the presently existing system, since the output of the other system will not be lost and can be reproduced when the signals of the existing system have ceased.

Abstract: A method and system are disclosed for locally introducing fluid, such as a gas, at a predetermined location into molten resin downstream from a resin injection aperture to form a hollow part. The gas is utilized at the localized area to distribute the molten resin, to eliminated molded in stress and to prevent formation of sink marks in the part during resin solidification. An overflow reservoir (112) outside of the mold cavity (114) is filled with the resin during resin injection and then the gas is introduced into the reservoir (112) through a fluid aperture (116, 118) and into the part. The reservoir creates a cocoon of solidified material to act as a seal to prevent gas leakage. One hollow body formed by the method and system includes a substantially endless hollow body portion with a fluid opening for communicating the interior of the hollow body portion with the locally introduced fluid. The hollow body provides an internal gas manifold and means for greater structural integrity.

Granted: 1993-03-03
Abstract: An apparatus for processing signals of a pulse encoder electrically processes output signals from a signal generator to improve the resolution of the encoder. Sine wave signals and cosine wave signals supplied from the signal generator are converted into digital signals through first and second A/D converters, respectively, and are supplied to a signal conversion means which produces an analog amplitude level and position data depending upon the outputs of the first and second A/D converters. Thus, the circuit constitution ca be simplified, the space occupied by the apparatus can be reduced, and the intensity of signals supplied from the signal source can be confirmed.

Abstract: An arrangement in explosive devices, e.g. shells, mines, bombs or the like, including a fuse (3), a main charge (1) and an auxiliary charge (4) which is disposed between the fuse and the main charge and effective in detonating the main charge. The main charge (1) is encapsulated in a safety casing and separated from the auxiliary charge (4) by different mechanical obstructions. In accordance with the invention, the auxiliary charge (4) comprises a charge having directed explosive action of the type which on being detonated produces a mass jet of high-order energy and high velocity.
