In the initial operation phase of a data recording apparatus, a controller (9) detects the output signal of a position detector (8), thus determining whether or not the objective lens (62) of an optical head (6) is facing the non-recording region (B) of an optical disk (1). If the lens (62) faces the non-recording region (B), the controller (9) turns on a semiconductor laser (7), whereby the laser...

This invention relates to the use of plasma technology for coating thin polymer films on steel. The process utilizes DC power, system pressures of 0.01-1.0 torr, the steel substrate is made the cathode, and the anodes are equipped with magnetic enhancement. The result is a uniform, pin-hole free, dense organic coating. Furthermore, there is minimal deposition of the organic film on the anodes or i...

Silage is preserved by treating it with a small but silage preserving effective amount of the microorganism Propionibacterium jensenii or the genetic equivalents thereof.

An electroluminescent device comprises a film containing a phosphor. Means for causing movement of electrons in the film comprising a first layer on one side of the film and a second layer on the other side of the film are provided. The film includes a first material which is also present in the first layer. It has been noted that such a device has enhanced luminescence as compared to a convention...

A plurality of raster-scanned image variables are time-compressed and time-division multiplexed on a line-sequential basis for pyramid analysis. The resulting differential pulse code modulation is statistically encoded and assembled together with digital audio code and synchronizing code. The assembler supplies a serial stream of bits to a transmitter. Receiving apparatus for a video teleconferenc...

The process provides for the structural reinforcement of manufactured articles made of stone or, in general, agglomerates by means of a sequence of steps which comprise the following: (a) the article to be treated is heated; (b) spraying on one surface of the article a particular adhesive called primer; (c) spraying on the same surface a resin preferably containing glass fibers or fibers of anothe...

A device (1) making it possible to apply at least one thread (2) to a support (3) and characterized by the following features: it has a front clamp (4) and a rear clamp (5) along a direction of advance (F1); it has means (6, 7) for opening and closing said clamps (4, 5); it has means (8) permitting the displacement of the rear clamp (5) in the direction of advance (F1) or in a direction (F2) oppos...

Acid resistant concrete articles, especially sulfur concrete pipes manufactured from a material formulated on the basis of a composition of portland cement concrete suitable for the manufacture of pipes by means of the dry casting method, the volume of portland cement, filler and water being replaced by a substantially equivalent volume of sulfur cement and filler, while the amount of other compon...

In an MRI (magnetic resonance imaging) apparatus, MR (magnetic resonance) images of a subject for animation-display are acquired in accordance with a predetermined timing. The timing is obtained by measuring a signal representing a biological phenomenon, for example, an electrocardiogram signal. The acquired MR images are corrected. An ROI (region of interest) for the MR images is set and standard...

A Q-switched laser having a gain medium disposed within a first cavity and a second cavity whose optical path length is adjustable such that the quality of the first resonant cavity is affected. One aspect of the invention is the changing of the physical path length of the second cavity so as to affect the reflectivity of a mirror common to both cavities as seen from the first cavity. Another aspe...

A data processing machine is provided with a microprocessor that functions in response to signals output by a clock oscillator to selectively change the data-processing speed of the microprocessor. The data processing machine contains a circuit for generating interruption signals at specific intervals by dividing the signals output by the clock oscillator, a signal-input device for inputting comma...

A motor vehicle headlight having a reflecting body which consists of a paraboloid of translation with inclined lateral end walls characterized by the fact that a spherical reflector is formed centrally on the paraboloid. A condensing lens is located ahead of the light source and a diaphragm is situated between the light source and condensing lens. The focus points of the condensing lens and spheri...

A steel rule die is disclosed having strengthening layers bonded to the die board to stiffen the die board against flexing during handling, while alleviating the tendency to loosen the steel rule during handling and enhancing the durability of the die. KEVLAR graphite fiber fabric is impregnated and bonded to either face of the die board with epoxy resin.

An electrocardiographic monitoring system in which the heart-signal sensing electrodes are each coupled to the heart-signal monitor/recorder by respective wireless transmitters and corresponding respective receiving wireless receivers in a base unit, each transmitter-receiver combination operating (in the absence of an encoding system) at a separate radio frequency, a zero or reference signal bein...

The muscle efficiency of a living animal is evaluated with apparatus comprising a nuclear magnetic resonance (NMR) analytical device that comprises a hollow electromagnet having a bore of sufficient size to receive the animal. A treadmill within the bore and beneath the animal is utilized to produce locomotion of the animal at different rates of work. The NMR analytical device is used to measure a...

A package for use in cooking or heating a food product in a microwave oven which comprises an outer paper container and an inner liner and a microwave interactive heater comprising a coating composition printed onto the surface of a suitable substrate or a selected portion of the outer container or inner liner. The coating composition preferably comprises finely divided carbon, aluminum flake, cla...

In a multiprocessor system, an error occurring in any one of the CPUs may have an impact upon the operation of the remaining CPUs, and therefore these errors must be handled quickly. The errors are grouped into two categories: synchronous errors (those that must be corrected immediately to allow continued processing of the current instruction); and asynchronous errors (those errors that do not aff...

A purification system for cooling tower water where no antiscalent chemicals need be added when the water is provided from a municipal source.
