Patent JP-S6484598-A (JP)
Title: Discharge lamp lighting device
Inventor: HAYASHI NOBUHIRO
IPC: H05B41/298
Filed: 1987-09-26
Abstract: PURPOSE:To obtain a discharge lamp whose filament service life is not damaged by setting a mode to a double spot mode during high output operation while switching to a single spot mode during low output mode at the time of dimming of the lamp. CONSTITUTION:A double spot mode turns switches SW1, SW2 ON during high output operation. An AC power supply e1 applies AC voltage to an end of each filament F1 or F2. Similarly, an AC power supply e2 applies voltage to the other end of each filament F1 or F2, so lighting is performed by a double spot mode. A single spot mode turns switches SW1, SW2 ON. The power supply e2 is supplied to the end of each filament F1 or F2 through condensors C1, C2 in a different way as before, so it is operated in the single spot mode. It is thus possible to prevent the service life of the filament of the discharge lamp with the optimum maintenance of filament temperature over a wide range.

Title: Image signal reproducing device
Inventor: ARAIDA MITSUHISA
IPC: H04N19/00
Filed: 1993-09-28
Abstract: PURPOSE:To obtain a visually satisfactory even in the case of an undercodable block having a motion by subjecting the picture signal, which is decoded based on the motion vector of a block estimated based on the appearance condition of motion vectors, to signal processing. CONSTITUTION:An interpolating circuit 112 uses motion vectors of blocks around the error block detected by a motion vector detecting circuit 111 to estimate the motion vector of the error block, and thereafter, the estimated motion vector of the error block is used to rewrite data of the error block stored in a second field memory 109 by picture data in a third field memory 110, thus interpolating the picture. The motion vector detecting circuit 111 uses frequencies in appearance of relative vectors as data indicating the appearance condition of motion vectors. Since the motion vector is detected based on the frequency in appearance of the relative address (motion vector) in the search window of each block, the precision of motion vector estimation is improved.

Filed: 1994-10-05
Abstract: PURPOSE: To suppress equipment cost and to flexibly cope with demand fluctuation by mixing plural kinds of generated light different in wavelength, distributing the synthesized light and branching light of a preliminarily fixed wavelength or more from the distributed synthesized light. CONSTITUTION: Plural kinds of light different in wavelength which are different in wavelength one another are mixed, the mixed light is defined as optical groups for which wavelength multiplex is performed and the optical groups are distributed to transmission nodes 5-1 and 5-2. In the transmission nodes 5-1 and 5-2, at least one of the plural optical groups is selected, the light is modulated by the signal which is going to transmit the light and the light is outputted. The wavelength multiplex is performed for this outputted signal light by an optical star coupler 7--1 and the light is distributed to reception nodes 9-1 and 9-2. Even when plural wavelengths are used in any of the transmission nodes 5-1 and 5-2, the light becomes the signal group for which the wavelength multiplex is performed by the optical star coupler 7-1.  Therefore, the number of selected kinds light can be freely controlled unless the used wavelengths are overlapped between all the transmission nodes 5-1 and 5-2 inputted in the optical star coupler 7-1.
