Title: Wireless transmitter
Inventor: HATAKEI AKIRA
IPC: H04B5/00
Filed: 1997-05-21
Abstract: PROBLEM TO BE SOLVED: To reduce the power consumption of a circuit that suppresses overvoltage and requires much power consumption by storing an arithmetic equation that obtains a distance between an induction coil and a reception coil based on a self inductance, a mutual inductance and a detected current, calculating the distance based on the detected current and controlling a current flowing to the induction coil based on the calculated value thereby controlling the induced voltage of the reception coil. SOLUTION: At first, at application of power supply 2, a current flows to a power induction coil 3 via a resonance capacitor 51, a current detector 40 detects a primary current and a CPU 130 receives the detected current via an I/F 110. The CPU 130 calculates a distance between the induction coil 3 and a power reception coil 4 based on the received primary current according to an arithmetic equation stored in a RAM 120. The CPU 130 controls a voltage variable section 150 depending on the distance to vary a voltage of the power source 2 thereby controlling the primary current. Thus, an induced voltage in the power reception coil 4 from the power induction coil 3 is selected to be a proper range by controlling the primary current.

Abstract: PURPOSE:To provide a process for producing an optical fiber coupler capable of controlling an actual stretching speed with respect to a target stretching speed set in such a manner that the speed is decreased which progressing stretching by stretching an optical fiber while applying specified tension thereon. CONSTITUTION:Data is read in from an optical power meter (S1) and a branching ratio is calculated (S2). The target stretching speed is determined according to this branching ratio (S3). Data is taken in from a moving length detector of a stretching stage (S4) and the actual stretching speed is calculated (S5). A gas flow rate is calculated in accordance with the ratio between the target stretching speed and the actual stretching speed (S6) and the gas flow rate is changed (S7). Fresh data is read from the optical power meter (S8) and the branching ratio is calculated (S9). The step is returned to S3 and the stretching is continued if the result of the calculation does not attain the desired branching ratio. The stretching is stopped (S11) when the branching ratio attains the desired target value (S10). Namely, this method changes the target speed of stretching according to progression of the stretching.
