IPC: H04B7/24
Filed: 1986-06-30
Abstract: PURPOSE:To constitute an economical system to a medium scale demmand between an opposite system and a TDMA system by allowing a base station to send plural carriers with simultaneous modulation to each subscriber station without multiplex conversion to an input TDM signal and to send information from each subscriber station to the base station while inserting the information in a prescribed time slot of a radio frame. CONSTITUTION:The base station B uses a couple of radio carriers respectively to subscriber stations S1-S3 and makes communication in a continuous wave and transmission/reception equipments T1-T3 provided with a unidirectional antenna are connected to a common radio line terminator SLT. A transmission network TDM signal 100 becomes a radio TDM signal at a common section C of the terminator SLT, required information is given to an individual control bit in a radio addition bit at interface sections I1-I3 and sent from each transmission/reception equipment to each subscriber station. Each subscriber station selects only the information signal of each time slot. The information from each subscriber station is inserted into the assigned time slot in the radio frame and then sent to the base station B. Each interface section detects the information of the individual supervisory control bit in the radio addition bit and uses a radio frame synchronizing signal to apply the mutual timing adjustment and outputs each information signal to the common section C selectively.

Abstract: PURPOSE:To reduce an adjusted place so as to facilitate adjustment by impress ing the voltage of the movable contact of a variable resistor to voltage-divide the output voltage of a frequency-voltage converting means upon a vertical deflection circuit by voltage/ current conversion. CONSTITUTION:The F/V converter 1 generates a DC current proportional to the frequency of a synchronous signal. A transistor 2 receives this output, and executes impedance conversion and output shift.

IPC: C04B37/00
Filed: 1995-06-21
Abstract: PURPOSE: To provide a method for joining ceramic structures, sufficiently large in the joining strength and not causing the leakage of a gas in the joined structures. CONSTITUTION: A method for joining ceramic structures to each other comprises forming grooves 3a, 3b on the joining surfaces of the ceramic structures 1, 2, respectively, inserting a metal plate 3 larger in thermal expansion coefficient than that of the ceramic into the grooves. Since the ceramic structures 1, 2 are thus joined to each other with the metal plate 3 large in strength, the joint is strong. When the ceramic structures 1, 2 are used in a high temperature state, the metal plate is thermally expanded to closely adhere to the inner walls of the grooves 3a, 3b. Thereby, the sealability of the structures is improved, and the leakage of a gas, etc., in the joined structures can be prevented.
