IPC: H04B10/63
Filed: 1990-10-19
Abstract: PURPOSE:To stably receive each channel even for a multichannel optical frequency multiplex signal by making a receiving part recognize an optical frequency multiplex signal group each local oscillation light source is due to receive according to a group identification signal. CONSTITUTION:The group identification signal 50, 60, 70 for recognizing each receiving channel group 1 to 3 is sent from a transmitting side, and this signal 50, 60, 70 is laid on, for instance, the channel of the lowest optical frequency of the group 1 to 3. First of all, each local oscillation light source 201 to 203 recognizes the group identification signal of the signal channel group it is due to take charge of, and by counting the channels to a high frequency side from this channel by the number of the channels it is due to take charge of, it can correctly recognize the signal channel group it is due to take charge of. The light source 201 to 203 outputs local oscillation light only when the reception request signal of the channel it is due to take charge of arrives. Thus, each channel can be received in a stable state.

Then difference information Δa with destination telephone numbers of choice data just before is broadcast as destination telephone number information of choice data of succeeding choice numbers. Since the difference between the destination telephone numbers of the succeeding choice data and the data of the destination telephone numbers of a just preceding choice number is Δa, the capacity of the difference Δa is comparatively small and a one-digit figure may be often enough for the multiplexed transmission information and then the information compression rate is high.  The capacity of the information is compressed by applying multiplex broadcast to the information of the difference Δa in this way.

Title: Switching regulator
Inventor: FUKUCHI TAKESHI
IPC: H02M3/28
Filed: 1994-11-18
Abstract: PURPOSE: To provide a switching regulator for reducing high harmonic current components at the time of light load and rated load. CONSTITUTION: A control circuit is connected to a second DC output and a constant load current always flows. A choke coil L3 between an AC power supply and a primary smoothing capacitor C0 suppresses a charge peak current, thus drastically relaxes high harmonic current components. When a drive circuit connected to a first DC output operates, load current increases and a voltage between both terminals of a resistor R14 also increases and hence a transistor Q2 switch on, thus enabling the induced power of a secondary coil winding N4 of a transformer 1 to cause a triac TRI to switch on and to bypass the current of a power thermistor PTH. As a result, high harmonic current tentatively increases.  However, the operation ratio of the drive circuit is extremely low and hence there is no danger of failure due to the high harmonic current and also no current flows to the choke coil L3, thus reducing rated current value.
