Title: Vapor phase and solid phase catalytic reaction method
Inventor: KOBAYASHI HIROYUKI
IPC: B01J15/00
Filed: 1980-07-01
Abstract: PURPOSE:To acomplish denitration and desulfurization wigh hith efficiency by using honeycomb catalysts, and causing catalytic reaction at the velocity of gas flow higher than specific velocity of flow at the time of denitrating and desulfurizing the NOX and SOX in waste combustion gases through vapor phase an solid phase catalytic reaction. CONSTITUTION:At the time of removing the NOX and SOX in waste combustion gases by using honeycomb catalysts and causing gas phase and solid phase catalytic reaction, a required amount A of the catalysts is inversely proportional to areal velocity AV and therefore, increasing the AV value suffices. This necessitates increasing an apparent reaction rate constant (k). When in this case the velocity of gas flow increases more than a certain level, the constant (k) increases sharply, and the velocity of gas flow at which the (k) stabilizes by passing a transition area is set as the lower limit velocity of gas flow. The gas is caused to make catalytic reaction with the catalysts at the velocity of flow higher than this, whereby the denitration and desulfurization reaction is accomplished efficiently.

Patent JP-S61250625-A (JP)
Title: Optical element
Inventor: NISHIMURA YUKIO
IPC: G09F9/30
Filed: 1985-04-30
Abstract: PURPOSE:To obtain a distinct image having high contrast and resolution and to eliminate the limitation in an angle of field by sandwiching a liquid layer contg. a surface active agent having a Krafft point between a pair of substrates formed with heating elements on the surface of at least one substrate. CONSTITUTION:The greater part of the surface active agent deposits and exists in a solvent in the state (state below the Krafft point) in which the liquid layer 2 is not heated and therefore the incident ray 6-2 on the low-temp. region 4a of the liquid layer 2 scatters (diffuses). On the other hand, the surface active agent deposited in the prescribed position dissolves in the solvent and the liquid layer 2 exhibits light transmittability when the prescribed position of the liquid layer 2 is heated to the Krafft point or above by a heating means from the outside by the irradiation of, for example, an IR beam 5 according to an information signal. The incident ray 6-1 on the heated region 4 passes therefore approximately straightly through the liquid layer 2 and is emitted from the substrate 1. The heated region 4 restores the original scattering state when the temp. falls.

Title: Video disk player
Inventor: FUJII YUKIO
IPC: G11B33/10
Filed: 1988-04-15
Abstract: PURPOSE:To reduce the mental burden of a user by detecting time passage from an activation starting to an activation completion and the time passage from a search start to a search completion, and changing the background picture of pull-back, etc., or an output picture according to the time passage. CONSTITUTION:A switch 9 selects the output side of a switch 22 at the time of activation. Consequently, as rotation frequencies omega of a motor 3 increases from 0 near 1,800 rotations/minute, a pulse width W of a switching signal becomes wider. As a result, on the output picture, a black part is gradually expanded from a left edge. That is, the blue picture is gradually erased from the left edge. At the time of search, since the output of the switch 22 is fetched from an output terminal 10, the blue of output picture is erased according to the time passage from the search start to the search completion. Consequently, in both cases, the user can know the time point of the reproducing start or restart by the percentage of the erased output picture, and the mental burden can be reduced.

Abstract: PURPOSE:To make better the thermal responsibility of a regenerative reservoir and to regeneratively produce pieces of sharbet-like ice, by a method wherein a cold finger is used as a supercooling-removing means and is located above the surface of water, so as not to be in contact with supercooled liquid. CONSTITUTION:Water W in the state of supercooling by a supercooler enters a regenerative reservoir 1 at an outlet port 4 for supercooled water. A cold finger 14 of which the refrigerating surface faces downward is located above the surface of the water in the regenerative reservoir 1, so as not to be in contact with this supercooled water and the air at the under-surroundings of the cold finger 14 is refrigerated by applying an electric current. On the refrigerated air, a slowly downward flow occurs by the specific weight difference between the refrigerated air and surrounding warm-air, and water in the air is turned into ice crystals 15, and they reach on the surface of the water in the regenerative reservoir 1. For this reason, each of the ice crystals spread acts as a core and the water W in the state of supercooling is growing into a piece of ice. That is to say, the supercooled state is removed and the supercooled water is turned into sherbet-like ice crystals 15, at the rate corresponding to the degree of its supercooling.
