Title: Process for producing difluoromethane
Inventor: TSUDA TAKEHIDE
IPC: C07C17/20
Filed: 1995-06-07
Abstract: Difluoromethane is prepared by reacting dichloromethane and hydrogen fluoride in a liquid phase in the presence of a fluorination catalyst under reaction conditions in which the reaction pressure is between 1 and 10 kg/cm 2 ab., and the reaction temperature is between 50 and 150°C, provided that the selected reaction temperature is higher than a temperature at which hydrogen fluoride is not liquefied under the selected reaction pressure. 
     Under the above conditions, the conversions of dichloromethane and HF are very high, and amounts of by-products other than R30 are very low, typically less than 0.1 % per difluoromethane, when the unreacted materials are recycled. 
     A material of a reactor is hardly corroded by the reaction using an antimony chlorofluoride and HF which are highly corrosive, as long as the above conditions are maintained.

Abstract: Non-coherently demodulated signals are efficiently decoded using a non-complex system that is independent of the fading statistics of the channel. A symbol metric calculator (406) receives a signal-to-noise ratio (404) and symbols from a non-coherently demodulated signal (402) to efficiently produce weighted symbol metrics (408). A symbol metric deinterleaver (410) is then used to deinterleave the weighted symbol metrics. A decoder (414) produces a decoded bit sequence (416) based on the deinterleaved weighted symbol metrics (412).

Abstract: Synthetic clay minerals are made up of elementary three-layer platelets consisting of a central layer of octahedrally oxygen-surrounded metal ions (octahedron layer), which layer is surrounded by two tetrahedrally surrounded, silicon atom-containing layers (tetrahedron layers), a number of such elementary platelets being optionally stacked. The dimensions of the clay platelets vary from 0.01 mum to 1 mum, the number of the stacked elementary three-layer platelets varies from on average one platelet to twenty platelets, while in the octahedron layer at most 30 at. % of the metal ions has been replaced by ions of a lower valency and in the tetrahedron layers at most 15 at. % of the silicon ions has been replaced by ions of a lower valency, such a replacement having taken place in at least one of these layers and these layers having a deficiency of positive charge because of the replacement. They are prepared by bringing the pH of an aqueous liquid containing the components of the clay to a value of 3-9 and the temperature of the liquid to a value of from 60 to 350° C. and maintaining it at said value for the time required for the reaction, the pH being maintained at a value within said range.

Abstract: An IC test handler with a constant temperature chamber comprising six planet IC holders 71, a planet holder arranging mechanism 72, and an intermittent rotation driving mechanism for intermittently rotating the mechanism 72. Each planet IC holder has four surfaces S of rotation symmetric with respect to a shaft 71a for the planet, the four surfaces S functioning as IC holding parts. The planet IC holders are arranged in an annular array on the planet holder arranging mechanism 72 that can rotate around a shaft 72a for a sun. The six planet IC holders 71 can revolve around the shaft 72a for the sun while the mechanism 72 makes one rotation. The intermittent rotation driving mechanism intermittently rotates the planet holder arranging mechanism 72 an angle by an angle of 60 ° so that ,when each planet IC holder 71 makes one revolution in the clockwise direction, it rotates by 90° on its own shaft. When a driving gear 73e and a solar gear 73b rotate, the six planet gears 73d slowly revolve around a shaft for the sun accompanied by the rotation of a rotating plate 73c while rotating in the clockwise direction on their own shafts. After 24 intermittent operations, the IC 4c attached to an IC holding part H is returned to its initial position. During this period, the temperature of the IC 4c on the IC holding part is sufficiently kept constant. Thereby, the number of preheated ICs in the IC constant temperature chamber can be increased, the tact period can be shortened, the staying time for the preheating can be elongated, and the space efficiency in the chamber can be improved.

Abstract: An apparatus (10) and method for printing graphic images by laser thermal transfer uses a laser source (32) and a programmable pulse generator (44) to transmit a pulsed infrared laser beam (42) in accordance with a printing program of image data to print graphic images on sheet material (S). The pulsed laser beam (42) is transmitted through a focusing lens (34), and the focused beam is in turn scanned by a scanning device (36) through a laser window assembly (38,138) into an ink web (W) along a line of laser impingement. The ink web (W) contains a layer of printing ink and overlies the sheet material (S) supported on a roller platen (40). The laser window (38,138) presses the ink web (W) into the sheet material (S) against the roller platen (40) along the line of laser impingement to facilitate the transfer of ink from the web (W) to the sheet (S) in accordance with the printing program of image data. The focusing lens (34) and laser window (38,138) are highly transmissive at the selected wavelength of the laser beam (42) to permit the passage of substantially all radiation into the layer of printing ink along the line of laser impingement.

Le nombre d'électrons par seconde en circulation dans un faisceau d'électrons modulé est déterminé par un signal d'image (Pi). On produit un faisceau d'électrons modulé corrigé en réduisant le nombre d'électrons par seconde en circulation dans le faisceau d'électrons modulé depuis le centre de l'écran d'affichage (10) vers ses bords, et par conséquent la taille d'un spot produit par le faisceau d'électrons modulé corrigé sur l'écran d'affichage (10) n'augmente que faiblement ou bien n'augmente pas du tout vers les bords de l'écran d'affichage (10). On peut réduire (2) le nombre d'électrons par seconde circulant dans le faisceau d'électrons modulé à l'aide, par exemple, d'une commande de contraste adaptée à cet effet. La réduction (2) du nombre d'électrons par seconde en circulation dans le faisceau d'électrons provoque une diminution de la lumière vers les bords de l'écran d'affichage (10).
