Title: System for preventing momentary interruption of mobile communication
Inventor: SAITO YASUYUKI
IPC: H04W24/00
Filed: 1995-04-25
Abstract: PURPOSE: To delay operator's radio wave interruption detection timing in an area of which radio wave state is deteriorated by providing a radio base station with a receiving electric field monitoring part for detecting momentary interruption (II) of communication and a receiving part for receiving an II prevention signal outputted from a mobile station and providing the mobile station with a transmitting part for transmitting the II prevention signal at the time of depressing an II prevention button. CONSTITUTION: When a timer in a mobile station 1 or a radio base station 2 generates time-out in each 0.1sec e.g. and when a receiving electric field value is smaller than a threshold, a radio wave interruption judging counter is set up to '+1'. When the value is more than the threshold, the counter is set up to '0'. A control part 15 or 25 judges whether II prevension is ON or not, and at interruption judging time or more, the transmission of a radio wave is stopped. Thereby the mobile station 1 outputs a busy tone to a handset 10 and the base station 2 outputs a mobile ring-off signal to an exchange 7. At the time of releasing an II prevention button stored in the mobile statation 1 when a radio wave state in communication is fine or II prevention is unnecessary, an II prevention OFF signal is transmitted to the base station 2. Consequently received radio wave interruption judging time can be extended.

Abstract: PURPOSE: To improve thermal efficiency and promote the efficiency of disposal by evaporation of sewage, etc. by a mechanism wherein the surface of an outer circumference of a cylinder body is formed in a corrugated shape, and a hot wind is circulated in a tank.  
     CONSTITUTION: A burner 4 is ignited to heat a corrugated cylinder body 3, and a large amount of heat is discharged into a tank 2.

Title: Circuit board
Inventor: TAKEDA TETSUSHI
IPC: H05K1/02
Filed: 1995-04-25
Abstract: PURPOSE: To provide a circuit board capable of suppressing switching elements from generating heat while reducing the size of an apparatus. CONSTITUTION: The flux from an inverter transformer Tr or a choke coil L1 diverges in air from one end face and returns to the other end face. Since the magnetic reluctance of a ferrite member 16 is so small, compared with that of air, the flux from the transformer Tr or a coil L1 mostly concentrates to this member 16 and hence the flux passing through a field-effect transistor Q1 can be greatly reduced. The eddy current produced in the transistor Q1, esp., its drain electrode is very small and even if the transistor Q1 is oscillated at a high frequency, the generated heat can be reduced.
