Title: Display system for television conference among plural points
Inventor: NAGASHIMA KUNIO
IPC: H04N7/14
Filed: 1986-09-30
Abstract: PURPOSE:To attain a multipoint television display that is excellent in a man-machine interface and offers a low-priced terminal by always displaying videos from plural conference terminals on plural subscreens of the same display, selecting any one of the videos from the conference terminals according to a control signal and displaying the selected one on a main screen. CONSTITUTION:The picture signals (a)-(c) from the conference terminals are applied to the input lines 210-212 of a lattice switch 200 in a 3 X 3 matrix. If the opening and closing of switch elements 201-209 is controlled according to requests from the conference terminals, the picture signals (a)-(c) are selectively applied to 1st inputs in screen synthesizing circuits 100-102. The picture signals (b) and (c) are further applied to 2nd and 3rd inputs in the screen synthesizing circuit 100. The same is true for the circuits 101 and 102. Thus the circuit 100, for instance, syntheizes a new picture signal (a') which displays the signals (b) and (c) on two subscreens and the signal (b) that the lattice switch 200 selects on the main screen, and transmits the signal (a') to the display device 216 of the conference terminal. Thus the videos B and C of other conference rooms are always displayed on the two subscreens of the display device 216. Simultaneously the video of any conference room can be switched and displayed on the main screen if necessary.

Title: Photoelectric converter
Inventor: MIYAWAKI MAMORU
IPC: H04N5/335
Filed: 1988-09-20
Abstract: PURPOSE:To reduce a fixed pattern noise and to attain high S/N by connecting a capacitor means controlling a potential of a main electrode area to the main electrode area extracting an output corresponding to a stored carrier. CONSTITUTION:A pulse phiVRS descends at the end of transient reset, an n-channel MOS transistor(TR) 9 is turned off, and as soon as the emitter 4 reaches the floating state, a pulse phiCOXE rises from a terminal 51. In this case, the emitter potential rises rapidly via a capacitor COXE 50 provided to the emitter side. When the amplitude of the phiCOXE or the capacitance of the capacitor COXE 50 is increased, the base-emitter potential might be biased reversely. Thus, the potential difference between the base and emitter is smaller than the state just before the transient reset. That is, the npn TR is turned off rapidly by raising the pulse phiCOXE to suppress the feedback and the increase in the fixed pattern noise just after the end of transient reset is suppressed.

Abstract: PURPOSE:To enable an accurate control of air-fuel ratio to be continually performed, by correcting a change of the output characteristic due to a stain of a hot wire in a hot-wire (HW) sensor, in the case of an electronically controlled fuel-injection engine. CONSTITUTION:On the basis of output voltage from a hot-wire (HW) sensor 10, a change of the output characteristic due to a stain of the HW sensor corresponding to an integrated intake air amount SIGMAQa is corrected through the action via each step of an intake air amount calculating means 22, intake air amount integrating means 23, HW output correction amount calculating means 24 and an HW output correcting means 21. The basic fuel injection quantity Tp is obtained on the basis of an intake air amount Qa, obtained by this corrected HW sensor output, and an engine speed Ne.

Title: Bipolar logic circuit
Inventor: KITORA KOJI
IPC: H03K19/013
Filed: 1987-09-16
Abstract: PURPOSE:To prevent the delay of tPLH (output L H propagation time) by charging output load capacitance quickly even when a noise is applied on an output terminal, by providing a transistor whose emitter is connected to the output terminal and whose collector is connected to a low potential power source terminal, and connecting a variable power source to the base. CONSTITUTION:The base potential of the transistor(TR)10 is set in the forward direction of an SBD11, and in case of applying the noise of negative voltage less than VF(SBD11)-VBE(Tr10) on the output terminal 4, the TR10 is energized, collector current with current amplification times the base current flows from a low potential power source 2. Since the current flows on the output terminal 4, the output load capacitance is charged quickly. As a result, a path from the emitter of the TR5 to the clamp SBD of the TR6 is interrupted, and the TR5 is set a de-energized state, thereby, the delay of the tPLH can be prevented from being generated.
