Abstract: A steam sprayer is used in ironing textile products, including clothes. The steam sprayer is user-friendly and offers highly effective ironing. A vaporizing chamber generates steam by vaporizing water stored in a tank. A water-supplying unit supplies the vaporizing chamber with the water. A steam-ejecting section spouts the steam outside. The steams-ejecting section includes a ironing surface with high frictional resistance characteristics. When touching the ironing surface to clothes or other fabrics for ironing, a pulling force is caused by the frictional resistance, which is a preferable wrinkles-off effect. Thus, the steam sprayer offers a synergistic effect brought by spouting the steam and applying the pulling force to clothes, thereby neatly fixing the form of clothes.

Abstract: An iron comprising a bottom member as an ironing face, which is provided with a plated metal film containing fluorine compound fine particles, so that the ironing face provides high surface hardness which shows less wear, good slidability and less generation of static electricity.

Abstract: An iron has a first base to be directly heated for increasing an amount of accumulated heat, a second base including a soleplate and a thermal resistance layer disposed between the bases. The thermal resistance layer has a greater heat resistance than the first base so that the first base heated by a heater can maintain a higher temperature than the second base. The iron of the present invention can increase an amount of accumulated heat, thereby extending not only an ironing period but also a period for spraying steam. If a weight of the iron is decreased, the iron still can hold approximately the same accumulated heat as a conventional iron so that a lightweight iron can be provided.

Abstract: Disclosed is a process of preparing a catalyst supporting highly metal particles comprising, in the presence of carbon monoxide in a solution containing a metal-containing ion and a support on which metal particles produced by reduction of the metal-containing ion are supported, reducing by means of a reductant the metal-containing ion to the corresponding metal particles which are then supported on the support. According to the process of the present invention, because of the presence of the carbon monoxide which is supposed to have a function of depressing the deposition of a new metal particle present around the metal particles supported on the support, that is, the growth of the metal particles and another function of preventing the agglomeration among the metal particles supported, the catalyst of excellent properties having the metal particles supported and monodispersed on the support with the narrow particle size distribution can be prepared of which an average particle size is not more than 20 .ANG..

Abstract: Disclosed herein are a platinum alloy catalyst comprising an electroconductive support and platinum-nickel-cobalt alloy particles having an ordered structure supported on the electroconductive support, and a process of preparing the catalyst. The catalyst possesses higher activity and longer durability because of its ordered structure.

Abstract: Disclosed herein are a platinum catalyst and a process for preparing the same. The catalyst comprises carbon supports and the carbides of (i) platinum and of (ii) one or more metals selected from the group consisting of nickel, cobalt, chromium and iron, and if necessary of (iii) manganese, supported on the carbon supports. The catalyst possesses superior catalyst performance because the catalyst metals are firmly fixed to the carbon supports by means of the carburizing.The process for preparing the platinum catalyst includes alloying the metals by employing their organic acid amine salts. This alloying requires a lower temperature than that in a conventional process so that the movement of the metals which leads to agglomeration thereof can be advantageously prevented.

Abstract: Disclosed herein is a process for reducing metal salts in which catalyst metal containing ions are reduced to the corresponding metals with a reducing agent which contains a sulfur atom and is relatively weak in reducing ability such as sodium thiosulfate, potassium thiosulfate, ammonium thiosulfate, sodium metabisulfite, potassium metabisulfite and ammonium metabisulfite. Since the reducing agent is weak, the size of the catalyst metals supported on the supports is small to enhance the catalytic activity.

Abstract: Disclosed herein is a process for alloying metals on inorganic supports comprising applying the solution of an organic acid amine salt of a second metal onto the inorganic supports already supported with a first metal; reducing the salt to the corresponding metal; and alloying the metals by heating.According to the present invention, the alloying of the metals can be performed at a relatively low temperature. Therefore, a highly active binary or ternary catalyst having a large surface area can be obtained.

Abstract: A centralized monitoring system for gas leakage in which a plurality of remote terminal units are connected by a loop line and each remote terminal units is further connected to one or a plurality of gas leakage detectors which produce analog signals representing the degree of gas concentration. Each remote terminal unit converts the analog signals from the gas leakage detectors into digitally coded block data and then transmit the block data together with an address code in time division fashion to a central monitoring station also connected to the loop line for processing the block data to provide display of the status of the gas concentration at the central station. In the transmission of the data through the loop line, a double transmission check system and a loop line switching means are employed to achieve reliable and fast data transmission.
