Abstract: A one-way valve (1) for feeding nozzles in injection assemblies for thermoplastics is described, comprising a stem (2) which is rigidly associable with the end of a screw feeder (4) in a thermoplastics conveying channel (5) proximate to the delivery end of the conveying channel and a valve body (8) including a substantially tubular portion (8a). The valve body is mounted axially slideable on the stem (2) and is provided with a passage (9) in an axial direction for the thermoplastics fed by said screw. On the stem there are provided, on opposite sides with respect to said body, a fist abutment (14) and a second abutment (16), the first abutment, facing said screw (4), being engageable with said body (8) to occlude said passage (9) when said screw is advanced towards said delivery end. In order to eliminate wear-out problems with a simple and cheap structure, the body has at least two spokes (10a, 10b) extending in the direction of said stem (2) from the substantially tubular portion (8a) at an edge thereof not facing said first abutment (14). The spokes define a shoulder (18) which is engageable with the second abutment (16) during the backward motion of said screw, and form between each other openings (11a, 11b) for the flow of thermoplastics material through the body (8).

Abstract: A high voltage detecting circuit included in a semiconductor device has a terminal (2) for generating a control signal to start a specific operating mode of the semiconductor device when a potential of a specific mode signal higher by a predetermined value than a normal input voltage having a predetermined range is applied to the terminals (2). The high voltage detecting circuit includes level shift means (4) connected between a blocking transistor (Q3) and a discrimination circuit (5) to lower the potential of the output end by a level shifted value from the potential of the input end. The level shift means (4) prevents the high voltage detecting circuit generating a control signal in error even if the semiconductor device is switched ON and a power line potential (Vcc) of the device is gradually increased while a normal mode signal of the normal input voltage is continuously applied to its terminal (2).

Abstract: A liquid filled differential pressure detector comprises two pressure sensors. Each sensor is constructed of one or more capsules, which are pairs of diaphragms sealed at their periphries. The innermost diaphragms are interconnected by a tube which contains a rod assembly. The interior of the sensors and interconnection tube form a sealed volume filled with a incompressible liquid. The rod assembly contacts the outermost diaphragm of the sensors and is displaced by expansion and contraction of the capsules caused by a differential pressure change against the outer surface of the sensors. The motion of the rod assembly is transformed into an electrical signal to indicate the pressure measurement. The apparatus is symmetrical about the center point of the tube to reduce error caused by the fluid's thermal expansion by causing equal and opposite forces to cancel, thereby preventing motion of the rod assembly. An overpressure condition results with one sensor completely collapsing with one diaphragm bottoming out against the other, but causes no damage to the capsules due to complementary facing of the diaphragm pairs. The compliance of the diaphragms is chosen to be small enough to cause any gaseous bubbles to be driven into solution during the initial prepressurization of the fluid, ensuring its incompressibility. In a second embodiment, the rod assembly is replaced with a core assembly located at the midpoint of the tube, suspended in a magnetic fluid which separates the incompressible fluid into two identical volumes. The motion of the core assembly, which is due purely to the displacement of the incompressible fluid, is transformed into an electrical signal to indicate a pressure measurement.

Abstract: Aqueous bleaching agent suspensions based on a water-soluble peroxycarboxylic acid suspended in a carrier liquid in the presence of an organic thickening agent and of an acidifying agent exhibit an improved storage resistance over known suspensions with this base. This is achieved by means of pourable to pasty bleaching agent suspensions which contain a xanthan polysaccharide or agar polysaccharide as thickening agent and, in addition, a hydrate-forming neutral salt which desensitizes peroxycarboxylic acids. Preferred suspensions exhibit a pH of 2-5 and contain 10-30% by wt. diperoxydodecanedioic acid, 5-20% by wt. sodium sulfate and 0.1-1.0% by wt. xanthan. The use of non-dried, hydrophilized and optionally in situ desensitized peroxycarboxylic acids is especially preferred. The bleaching agent suspensions are prepared by homogeneously suspending the peroxycarboxylic acid in the thickened carrier liquid. The storage-resistant bleaching agent suspensions are used as laundry bleaching agents and for preparing cleaning agents and disinfection agents.

Abstract: In response to ultrafast optical signal pulses, it is now possible to generate correspondingly ultrafast electrical signal pulses by employing semiconductor apparatus including at least one quantum well layer electrically biased by a static electric field. Optical signal pulses incident on the quantum well are at a wavelength substantially less than the absorption edge of the quantum well layer or layers. In other words, the incident optical pulses have a mean photon energy less than the bandgap energy of the quantum well layer or layers. The electrical signal pulse generated subsists for a period of time substantially equal to the duration of the optical signal pulses incident on the quantum well layer or layers.

Abstract: A scanning optical microscope is disclosed in which the laser that illuminates the specimen is also used as a component of the optical detector system. This dual use of the laser permits substantial simplification of the microscope optics and the associated scanning mechanism. For example, the beam splitters and other bulk optic components required in prior art devices are replaced by a single optical fiber linking the laser and the specimen. A micro-lens is formed on the terminal end of the fiber to focus the laser light onto the specimen. The optical fiber is mounted over the specimen and its terminal end portion is caused to swing back and forth in reciprocal motion above it, this motion being induced by electromagnetic or electrostatic interaction between the fiber and associated electromagnets or deflection plates. The periodic drive signals that induce this oscillatory fiber motion are synchronized to the fiber's natural mechanical resonant frequency by an optical position detector.
