IPC: H04H60/27
Filed: 1987-05-15
Abstract: PURPOSE:To shorten a transmission time, by sending broadcasting content data from a master station to plural slave stations with a simultaneous multiple address communication system. CONSTITUTION:The operator of a master station equipment 111 inputs broadcasting data by using a microphone 1. A control part 5, after sending a time difference instruction signal, sends the signal of the broadcasting content data as a wave via a radio equipment 2. Broadcast is performed at a group A slave station equipment 112 immediately based on the broadcasting content data, and the broadcasting content data is stored in a storage device 26 at a group B slave station equipment 113. And after the lapse of a prescribed time, the broadcasting content data stored in the storage device 26 is read out, and is sent to a power amplifier part 23. Since the master station equipment 111 performs simultaneous multiple address communication, communication can be performed in a short time, and it is possible to prevent inconvenience such as no transmission of data to a part of slave stations due to the fault of the master station equipment from being generated.

Abstract: PURPOSE: To form a lustrous solver-colored salt glaze film proof against frost damage and discoloration by contacting a calcined product in a smoking kiln to mixed gas of smoking gas and salt gas.  
     CONSTITUTION: A base material such as a tile is placed in a kiln and calcined. When the temp. of the material reaches about 1000W1500°C, the calcination is finished. A smoking material such as wood or coal and salt are rapidly charged into the kiln from the fuel hole, and the hole is closed. The hole is then opened slightly to charge salt into the kiln little by little in few stages so that salt gas flows evenly, and the hole is closed. The kiln is cooled to below 300°C in the hermetically sealed state, and it is opened. Mixed gas of salt gas and smoking gas fills the kiln and contact to the base material surface of the calcined product to form a silver- colored glaze film.

Filed: 1990-05-07
Abstract: PURPOSE:To provide an electrode catalyst layer for a phosphoric acid type fuel cell which is excellent in stability of output voltage by using a catalyst carrier whose surface is composed of a carbon black region and a carbon fluoride region. CONSTITUTION:An electrode is formed of a catalyst carrier 2 with noble metal 1 such as platinum supported and an electrode catalyst layer 5 with fluorine resin 3 as a water-repellent material uniformly mixed laminated on an electrode substrate 4 made of a carbon material which is porous and excellent in electrical conductivity. The surface of the catalyst carrier 2 is composed of a carbon black region and a carbon fluoride region, while the noble metal which is supported on the surface of the catalyst carrier forms catalyst and the fluorine resin 3 is used to bond the catalyst. The carbon black region of the surface of the catalyst carrier is well wetted with phosphoric acid. On the other hand, the carbon fluoride region is not wetted with phosphoric acid. The carbon fluoride region is to be in contact with reaction gas. Thus three-phase interfaces are stably formed on the surface of the catalyst carrier and infiltration of phosphoric acid can be prevented.
