Title: Multiple site video conference connecting method with different speeds and system
Inventor: KAMURA YUKARI
IPC: H04N7/15
Filed: 1997-05-09
Abstract: PROBLEM TO BE SOLVED: To simply construct intercommunications with different speeds and to suppress costs increase by decoding video from each terminal that has a different transfer rate, thinning it, synthesizing it, after that, encoding it with each transfer rate and sending it to each terminal. SOLUTION: An image signal that is inputted to a multiple site controller 1 through plural transmission paths 12a and 12b is inputted to a speed detector 2 and each transfer rate is detected. Decoders 3a and 3b decode each image based on transfer rate information from the detector 2 and an output is inputted to an image synthesizer 4. The synthesizer 4 thins moving images in a CIF format which is separately decoded, converts them into a predetermined size, synthesizes them through an enable signal which is inputted from a timing generator 5 to be one image and separately supplies them to encoders 6a and 6b. The encoders 6a and 6b encode them in their own speeds based on a transfer rate signal from the detector 2 and send them to each terminal through transmission paths 61a and 61b.

Title: Power device for incandescent lamp
Inventor: TSUZUKI TOMIO
IPC: H02M7/06
Filed: 1992-04-27
Abstract: PURPOSE:To light up a low-voltage and high-power incandescent lamp, for example, a halogen lamp, at the stabilized voltage, using a commercial AC. CONSTITUTION:A commercial AC is full-wave rectified by a diode stack D1 and then is applied to a halogen lamp L1 through an inverter circuit 12 and a high-frequency transformer T1. The voltage of a secondary winding C of the high-frequency transformer T1 is detected by a detection circuit 14 and the collector current of a transistor Q3 is controlled by means of the output of an operating amplifier IC2. When the voltage across a capacitor C1 which is charged by the collector current of the transistor Q3 exceeds the trigger voltage Ttr of a trigger diode D3 and the diode D3 comes to a conduction state, a charge of the capacitor C1 flows into a base of a transistor Q2 and oscillation begins. When the output voltage of the secondary winding C of the high-frequency transformer T1 becomes high, a charging time of the capacitor C1 becomes longer and a starting phase of high frequency oscillation gets delayed, resulting in stabilization of the voltage to be applied to the halogen lamp L1.
