IPC: H02M3/28
Filed: 1985-04-09
Abstract: PURPOSE:To prevent the secondary defect by providing a defect detector between the emitters of transistors connected in parallel and a current balancing circuit. CONSTITUTION:A DC/DC converter has a control circuit 1, a protecting circuit 2, a defect detector 3, a current balancing circuit 4, a transistor TR and a transformer T1, and supplies its output to a load R1. In this case, the detector 3 is provided between a power source E and the emitter of the TR. The detector 3 has diodes D3-D5, a capacitor C2 and a resistor R2. The circuit 4 has current transformers CT1-CT3, the secondary windings connected in series, and the primary windings connected in parallel with the emitters of the TRs. Thus, when the TR1 becomes, for example, defective so that the emitter becomes open, the balance of the primary side and the secondary side of the transformer CT1 is broken to conduct the diode D3. Thus, an output voltage is generated from a resistor R2, applied to the circuit 2 to stop operating the circuit 1.

The stem 4 supported by a stem holder 10 is located under the glass tube 1 facing towards the glass tube 1 at a distance L aparting from it. The periphery of the flare portion 5 is heated by a burner 12 under this condition, then the peripheral part of the flare portion 5 is softened and causes drag 5' by its self weight, and the outside diameter D becomes a little smaller. Subsequently, when the stem 4 is raised together with the stem holder 10 and the burner 12 in one body, the stem 4 is inserted within the glass tube 1, the flare portion 5 in the softened state hits the opening end 2 of the glass tube 1, and is pushed therein, and the peripheral part of the flare portion 5 makes close contact with the inside surface of the glass tube 1. Moreover, when the glass tube 1 and the flare portion 5 are heated with the burner 12, both are melted together at the same time.

Filed: 1999-03-19
Abstract: PROBLEM TO BE SOLVED: To allow a BS/CS common use converter to receive both BS and CS signals through both a right-handed rotatory channel and a left-handed rotatory channel. SOLUTION: RF amplifiers 1a, 1b amplify RF input signals S1a, S1b from a BS and a CS to a prescribed level, RF band pass filters 2a, 2b filter the amplified signals so as to allow mixers 3a, 3b to receive signals only at a prescribed frequency band. Then a synthesizer 7 synthesizes an output of the RF amplifier 1a of the right-handed rotatory channel via the RF band pass filter through which the RF signal of the BS passes with the RF signal of the CS of the left-handed rotatory channel. The RF signals of both the channels are mixed with a local oscillation signal from a local oscillator 5 at the mixers 3a, 3b to convert the frequency of the RF signals into an intermediate frequency.  IF amplifiers 4a, 4b convert output signals from the mixers 3a, 3b to have a prescribed level and a prescribed impedance and the result is outputted to a satellite tuner or the like as IF output signals S2a, S2b.
