Title: Mixed salt for evaluation of corrosion resistance to melted salt
Inventor: NOSE KOICHI
IPC: G01N17/00
Filed: 1995-02-10
Abstract: PURPOSE: To safely evaluate/test corrosion resistances of a metallic material under an environment close to the actual environment by using a mixed salt of a low melting point composed of sulfate or a chloride such as Na, Mg or the like as a main component of ash produced in the actual environment where dust is burnt. CONSTITUTION: A small amount of MgSO4 is added to NaCl, KCl and CaCl2 composed of sulfate or a chloride such as Na, K, Ca, Mg or the like as a main component of ash actually generated in an environment where dust is burnt, thereby to obtain a mixed salt B of 32 to 38mol.% of NaCl, 4 to 6mol.% of KCl, 13 to 17mol.% of MgSO4 and the remaining mol.% of CaCl2 and having a melting point of 480 deg.C or lower. The mixed salt B has corrosive properties nearly coincident with those of an actual furnace ash A within an error range of 4-8% in an ambience of nitrogen gas including 1500ppm HC and 50ppm SO2 and 10% O2 . Therefore, corrosion resistances can be highly reliably evaluated/tested. Since the components of the mixed slat B are stable at room temperatures and less deliquescent, the mixed salt is easy to handle with.  Moreover, since the mixed salt B does not include a heavy metal, human bodies are little harmed.

Title: Radio equipment
Inventor: SASAKI SATOSHI
IPC: H03G3/30
Filed: 1994-01-26
Abstract: PURPOSE:To improve the power efficiency of radio equipment at the time of transmission by subjecting a modulated wave signal to envelope detection, and controlling the bias operating point of a power amplifier corresponding to the amplitude of a detection signal. CONSTITUTION:A part of a carrier signal to be modulated inputted to a pre- amplifier 2 is subjected to envelope detection by an envelope detection circuit 5, and the change of amplitude of the wave signal to be modulated is converted into that of a detection output signal. The detection output signal is supplied to a bias control circuit 6, and controls the bias of the gate or base of the power amplifier 3. While, a switch 7 controls the circuit 6 corresponding to a timing control signal from a timing control signal input terminal 8, and performs the on/off control of the bias of the gate or base of the amplifier 3. The switch is operated so that the amplifier 3 can permit small and large drain currents to flow corresponding to the magnitude of amplitude of an envelope detection signal in a state where the timing control signal is set in an on-state. Consequently, since the bias operating point can be controlled corresponding to the change of amplitude of the wave signal to be modulated, the power efficiency of the radio equipment can be improved.

IPC: H04W40/22
Filed: 1997-02-06
Abstract: PROBLEM TO BE SOLVED: To attain mobile object communication over a wide area, without increasing an installed number of base stations in a communication processing system for mobile object communication. SOLUTION: Terminal equipment itself for mobile object communication is provided with a function of conditioning a repeating process of communication for other terminal equipment. In the case that transmission terminal equipment 1 transmits a connection request, the transmission terminal equipment 1 transmits the request to neighbor repeating terminal equipment 2a. The repeating terminal equipment 2a transmits a connection request received by using its relay function further to neighbor repeating terminal equipment 2b. Then the repeating terminal equipment 2b transmits the connection request to a neighbor base station 4a.  The base station 4a refers a position information database 5, based on the connection request, seeks a base station 4b in an area to which reception terminal equipment 3 belongs, and transfers the connection request to the base station 4b via a communication channel 6. The base station 4b transmits the connection request to neighbor repeating terminal equipment 2c, the repeating terminal equipment 2c repeats the connection request and transmits it to the reception terminal equipment 3. Thus, a communication repeating route is established.
