Title: Multi-point video conference system
Inventor: NAKAMURA SUMUTO
IPC: H04N7/15
Filed: 1994-10-18
Abstract: PURPOSE: To attain more natural multi-point video conference by detecting a voiced signal or a non-voiced signal before coding and detecting a video terminal based on the resulting detection signal so as to reduce a detection time thereby switching a screen earlier. CONSTITUTION: A voice signal before coding is subjected to smoothing for a prescribed time by a level detection circuit 2, and its mean power is given to a level comparator circuit 3 as voice level information. The circuit 3 compares the mean power with a reference signal. Since the circuit 3 detects a voiced signal or a non-voiced signal, a slightly higher level than a level at non-signal is set to the reference signal. Then the comparison result signal by the circuit 3 is inputted to a multiplexer circuit 34. Each signal received by a video conference controller 10 via transmission lines 50A-50N is separated into a level comparison result is signal and various data at a demultiplexer circuit 41.  The level comparison result signal is given to a talker terminal detection circuit 12, in which a talker is discriminated when the frequency of voiced signals exceeds a prescribed value and non-talker is discriminated when the frequency of non-voiced signals exceeds a prescribed value.

IPC: H04N5/911
Filed: 1991-09-30
Abstract: PURPOSE:To obtain a high quality reproduced picture by suppressing spurious componets of demodulated image signals. CONSTITUTION:In a spuriousness compensating circuit 40, an orthogonal carrier wave component Sa4, which is orthogonally crossed with respect to a speech carrier wave component Sa1, is formed by a phase shift circuit 43, supplied to multipliers 41a and 41b and a spurious component Ss1 is vector wise resolved into components Sa1 and Sa4 phases and detected. In the other pair of multipliers 42a and 42b, levels of each component Sa1 and Sa4 are controlled in accordance with the resolved and detected output of the component Ss1. In an adder 47, the carrier wave components from the multipliers 42a and 42b, which are level controlled, are vector wise composed and a compensation signal Sc1 is formed. Similarly, a compensation signal Sc2 is formed from the other speech carrier wave component Sa2, both compensation signals are phase reversed, respectively, supplied to an adder 19 and spurious components Ss1 and Ss2 in the demodulated picture signals are suppressed. Thus, no adjustment is required and good quality of the reproduced picture is kept.

Title: Loading control device of garbage collecting car
Inventor: INADA TOSHIAKI
IPC: B65F3/00
Filed: 1987-10-07
Abstract: PURPOSE:To improve the safety of a device in the title by connecting an electric contact point which can detect the arrival of a rotary plate at the position just before the throwing-in port and the electric contact point which relates to the contact operation of a treating device start switch at the time of operation of this contact point, in parallel to a self-holding circuit. CONSTITUTION:When a rotary plate 11 reaches the position just before it crosses a throwing-in port 8, an electric contact point LS10 is switched to the lower position so as to cut off a self holding circuit 2 to a relay R1. Consequently, the magnetization to a relay R3 is cut off through a relay contact point r1 so as to stop the rotary plate 11. Here a start switch SW3 is put in contact operation again. Thus, a relay R9 is magnetized through the electric contact point LS10 and put in self holding state through a contact point r9 at the same time. Consequently, the self holding to the relay R1 is recovered through the relay contact point r9 and the normal rotation of the rotary plate 11 is carried out again. By this composition, the safety of the device can be improved.

Title: Manufacture of film capacitor
Inventor: TERUI ISAO
IPC: H01G4/30
Filed: 1987-10-09
Abstract: PURPOSE:To prevent the center part of a capacitor element end face from protruding, by causing the first press to perform its pressing equally within a certain range of a temperature which is less than the softening point of a resin obtained prior to melting and further by causing the second press to perform its pressing within a certain range of a temperature, at which the resin melts, thereby performing step-pressing where the both end parts of the element can be pressed down strongly all the more as compared with the case of other parts. CONSTITUTION:Polyethylene thermal fusion layers 5 are arranged to form films in a body at the both faces of a base film 4 consisting of polyethylene terephthalate. The dielectric substance films 1. are wound by superimposing their films on metal electrode foils 2 alternately. And the films are pressed with heat by the first press 8. And then they are pressed down in a state that the thermal fusion layers 5 are not molten (that is within a temperature range which is less than a softening point). After that, the films are pressed down with heat furthermore by the second press 9. These measures prevent the end face parts of film layers from slipping off outwards even though the thermal fusion layers 5 melt together and allows the end faces 6 and 7 to keep their conditions flat and thus, they are fixed satisfactorily.
