Abstract: A herbicidal formulation comprising of incorporating the herbicide in a micelle or vesicle and adsorbing said micelle or vesicle containing herbicide on clay mineral. The formulation is suitable in particular for negatively charged herbicides at pH above 6. The herbicidal formulation provides slow release and reduced leaching of the herbicide to deep soil layers, thus reducing contamination of underground water and soil. Furthermore, the herbicide is maintained in the target vicinity, thus its efficiency is enhanced and a smaller concentration may be used.

Abstract: An electrical steering lock device and a related method are disclosed wherein a plate cam 17 has a contoured profile determined such that a lock shaft 15 moves inside a lock groove 13 at a travel speed (first speed) lower than a travel speed (second speed) at which the lock shaft 15 moves outside the lock groove 13, enabling the lock shaft 15 to disengage from the lock groove 13 with increased torque. This results in a capability of reliably disengaging the lock shaft 15 from the lock groove 13.

Abstract: Walking aid apparatus comprises handle portion and a shaft portion including a ground-contacting ferrule, the shaft portion comprising telescopically-mounted cylindrical spindle and sleeve elements and a spring means acting between seats of said spindle and sleeve elements resiliently to restrain relative axial sliding movement, in which the apparatus includes a sliding friction-reducing means between at least one end of the spring means and the associated seat, whereby the handle portion and the ferrule are axially rotatable to accommodate twisting movement as between the user and the ground in use. The sliding friction-reducing means results in controlled rotation as between the spring means and the spindle and/or elements with considerable benefits to the user in avoiding tortional loading to the twist, elbow and/or shoulder joints which can be especially painful to those who suffer from arthritis.

Abstract: The invention relates to a plug-in element (1) for an optical plug-in connection. Said element comprises a connector pin (2), which is held in a guide sleeve (4) by axial spring-loaded prestress, in such a way that it can be displaced in a limited manner along its longitudinal axis (3). The guide sleeve consists of at least two casing elements (5, 5?) that can be assembled along their longitudinal axes. Said casing elements significantly simplify the production and assembly, as no screw or adhesive connections are required.

Abstract: A quantum structure and the forming method based on the difference in characteristic of two matters is provided. The forming method includes several steps. At first, providing a first dielectric layer for forming a second dielectric layer thereon. The second dielectric layer has major elements and impurities contained. Treating the second dielectric layer to drive the impurities to form the quantum structure.

Abstract: The present invention relates to a method of purifying gaseous nitrogen trifluoride from CF4 as impurity. The method comprises selective adsorption of nitrogen trifluoride by dehydrated erionite at a temperature of from ?30 to 30° C., displacement of carbon tetrafluoride by an inert gas, desorption and condensation of the purified nitrogen trifluoride. The purification yields 99.99% pure NF3 with CF4 content not over 10 ppm. The proposed method of NF3 sorption purification makes it possible to carry out the process at an ambient temperature and with long operating life of the sorbent. The method is practically feasible, economically expedient, and easy to implement under industrial conditions.

Abstract: A recording apparatus generates key information based at least on contents reproduction permission information, encrypts contents based on the key information, and records the encrypted contents and recording date/time information on a recording medium. A reproducing apparatus reads the encrypted contents and the recording date/time information from the recording medium, acquires reproduction date/time information on the encrypted contents and, based on the recording date/time information that was read, the reproduction date/time information, and reproduction permission limit information on the encrypted contents, generates contents reproduction permission information indicating that the encrypted contents maybe reproduced. The reproducing apparatus generates key information based at least on the contents reproduction permission information and decrypts the encrypted contents that were read.

Abstract: A harmonic generation circuit compares audio data supplied from the outside every sample, detects a top-peak and an under-peak of the audio data on the basis of the comparison outputs, and detects patterns of the comparison output between continuous top-peak and under-peak. The harmonic generation circuit forms an addition-subtraction data corresponding to harmonic depending on the patterns, and supplies the addition-subtraction data to an adder at a timing depending on the patterns. The adder performs an addition-subtraction process for adding/subtracting the addition-subtraction data formed by the harmonic generation circuit to/from the audio data supplied from the outside. In this manner, with a compact, simple, and low-price circuit arrangement for performing only addition-subtraction, a harmonic component can be added to original audio data, and audio data having a wide frequency band can be formed.

Abstract: A method and system for measuring time variations of a response of a blood perfused fleshy medium to an external electromagnetic field is provided. The response of the medium to the external electromagnetic field can be a photo-acoustic signal, obtained in response to the exciting light, and/or impedance of the medium, in response to the applied ac electromagnetic field. Measurements of the time variations of the response of the medium are carried out when the condition of artificial kinetics is created and maintained over a certain time period by applying primary over-systolic pressure to a certain location at the medium with normal blood flow, so as to achieve a state of temporary blood flow cessation at the medium downstream of the certain location. When required, the control of the condition of the artificial kinetics can be further achieved by applying a perturbation of secondary pressure to the fleshy medium.

Abstract: The invention relates to work pieces (2), such as surgical instruments provided with a machine-readable data carrier (1). Said data support contains a data section (3) with individual cavities (4) arranged therein, forming a two-dimensional matrix code (5). The cavities exhibit a particular advantage in that they are machine-cut, especially by means of boring. Damage causing structural alterations to the material occurring when a code is burnt in by means of laser radiation can be reduced in a reliable manner. The contrast effect of the cavities is sufficient and the data support is particularly resistant to mechanical influences.

Abstract: First and second synchronous words having respective numbers of times of inversion different from each other in NRZI conversion are generated in a synchronous word generation portion, and first and second code word series data are generated by arranging code word data generated making reference to a run-length coding table after these two synchronous words. With respect to the first and second code word series data, DSV calculation results stored in two DSV calculation peak value memories corresponding to these data are compared with each other by a peak value comparison portion. Based on a comparison result, the code word series data having a smaller direct-current component generated in NRZI conversion is selected.

Abstract: An apparatus and method of line coding to mitigate collision induced errors in Wavelength Division Multiplexing (WDM) optical communications systems is disclosed. The apparatus and method prevents Soliton-Soliton-Collision induced errors by reducing a variance in a number of possible collisions between solitons in multiple channels in a WDM fiber optic communication system using a sliding window criterion. The sliding window criterion defines a set of parametric values based on physical properties of the transmission network, a transmission frequency and a defined data block size. N-bit codes are iteratively selected and sequentially assigned to segments of a mapping table indexed by all possible unique combinations of “1”s and “0”s in a block of data. Input data blocks are mapped to corresponding code words having a reduced number of transitions for transmission on the fiber optic network. Received code words are converted back to a data stream corresponding to the input data stream.
