Title: Method and device for controlling oscillation mode of vibration rotation sensor
Inventor: KUMAR LALIT
IPC: G01C19/567
Filed: 1998-03-20
Abstract: PROBLEM TO BE SOLVED: To control the oscillation mode of a vibratile rotation sensor(VRS) by supplying an AC sensing signal to a conductive area on a resonator to obtain a plurality of oscillation signals. SOLUTION: A resonator has the surface provided with a conductive area, and a housing has a plurality of electrodes mounted being positioned opposedly to the conductive area on the resonator. A parameter of a standing wave oscillation pattern of the resonator is determined by supplying an AC sensing signal to the conductive area on the resonator and obtaining one or two or more oscillation signals while the electric potential of the conductive area on the resonator is maintained within 100 mV from earthing. Each oscillation signal is a duplicate of the AC sensing signal with amplitude modulation, and amplitude modulation is a cycle function of distance from one point of the conductive area on the surface of the resonator to the opposed housing electrode. The frequency of amplitude modulation is the oscillation frequency of the resonator.  The parameter of standing wave is used to control a standing wave parameter by generating suitable AC forced driving voltage.

Title: Program constitution definition system
Inventor: OSHIMA MASATAKA
IPC: G06F9/06
Filed: 1990-03-20
Abstract: PURPOSE:To check error in the design stage of a module by defining call relations among respective modules constituting a program and call procedures among modules with each module as the unit and preserving them. CONSTITUTION:Call relations and call procedures among modules constituting the program are defined with each modules as the unit by a module constitution defining means 1-3, a module call procedure defining means 1-4, and a system common module defining means 1-5, and these definition information are held in a module definition information storage device 1-7 and a system common module definition information storage device 1-8. If definition information is set at the time of designing and producing the logical structure of a module, it can be checked whether the design is different from definition or not when declaration of call procedures of the modules is automatically generated and the logic to call another module from the module is designed. Thus, error in the logic design of the module is prevented.

Title: Image sensor
Inventor: IWAO HIDEMI
IPC: H04N5/335
Filed: 1990-03-22
Abstract: PURPOSE:To suppress a fluctuation of an output voltage due to a reverse current by connecting a diode between an output line and ground so as to suppress a reversing voltage caused on the output line of a current-voltage conversion circuit when a reverse current flows to a common current output line. CONSTITUTION:When a reverse current flows to a common current output line 3, a diode 7 is connected between an output line and ground so as to suppress a reversing voltage caused on an output line of a current-voltage conversion circuit 2. Thus, when the reverse current flows to a common current output line 3, a voltage reverse to that in the normal state is caused in an output stage of the current-voltage conversion circuit 2, a reverse voltage absorbing diode 7 is conductive to absorb the reversing voltage. Thus, the voltage due to a reverse current is suppressed and the operating speed of the image sensor is increased.

Title: Dc and ac coefficient prediction for intra-macroblock in interlaced digital video
Inventor: EIFRIG ROBERT O
IPC: H04N7/50
Filed: 1998-03-09
Abstract: PROBLEM TO BE SOLVED: To obtain a device for selecting a prediction coefficient for differential encoding of the AC and DC DCT coefficients of an intra-encoding block by identifying an adjacent left block, adjacent top block, and left block adjacent to the left block and to the top block. SOLUTION: At the time of inter-encoding, a current VOP is subtracted by a subtractor 160 from the preceding VOP compensated for its motion, and the residual is encoded by a texture coder 140. At the time of intra-encoding, DCT is executed for a DCT coefficient from the pixel data of a current block instead of the residual. The DCT coefficient itself is differential-encoded by using AC and DC coefficient values predicted from a selected block adjacent to a current block in the same VOP. The DC and the AC coefficients are differential-encoded by selecting the predicted DC and AC coefficients from a left adjacent block and a top adjacent block.

Abstract: PROBLEM TO BE SOLVED: To prevent generation of nonuniformity in toner density and form constant-quality images stably by controlling an adhesion force of toner to a toner hold roller and feeding the toner smoothly to an aperture. SOLUTION: A negative voltage is impressed by a d.c. power source 49 to roller electrodes 41a in the vicinity of immediately below an aperture 6 and a positive voltage is impressed by a d.c. power source 32 to an auxiliary electrode 31 set at a print head 1, whereby the roller electrodes 41a act a repulsion force to a toner 16 and the auxiliary electrode 31 acts an attraction force. Accordingly, an adhesion force between a toner hold roller 14 and the toner 16 is eased to a degree not allowing the toner 16 to fly. Since the toner 16 can be supplied smoothly to the aperture 6 by controlling a voltage of a control electrode 4, constant-quality images can be formed stably.
