A transmit packet generated by a CPU 1 is held in a buffer 100a (100b). From among packets received from Ethernet 820a (820b), a packet, a destination of which is a communication device 800, is held in the buffer 100a (100b). A packet which should be transmitted is transmitted from a transfer judging circuit 200 to Ethernet 820a or 820b through a MAC unit 300a or 300b. If a transfer judging circuit 200 judges a packet from the Ethernet 820a to be a packet, a destination of which is another communication device, with reference to a destination MAC address, this packet is transferred to the Ethernet 820b through MAC 300b. If a usage rate of a transferring FIFO buffer 130a (130b) exceeds a threshold value in the process of transmitting a packet held in a transmitting FIFO buffer 120a (130b) on a priority basis, the priority order of a transfer packet is made higher than that of a transmit packet so that the transfer packet is transferred to the Ethernet 820a or 820b in preference to the transmit packet. This prevents a transfer buffer means from overflowing.

A method of driving a display apparatus with which unevenness of image is precluded and the time for display is shortened. A display apparatus for displaying an image by impressing a voltage on pixels by row electrodes and column electrodes disposed in a matrix, for example, a metal deposition type electrochemical display apparatus. A voltage not less than a threshold voltage Vth is selectively impressed on predetermined pixels by superposing an address pulse voltage Vadress-row for the row electrodes and an address voltage Vadress-col for the column electrodes on each other to thereby perform address driving, and a data sustaining pulse voltage Vsus is impressed on the row electrodes immediately after the address pulse voltage Vadress-row. The data sustaining pulse voltage Vsus satisfies the condition of the following formula: Vsus+Vadress-col

The present invention is directed to providing a retroreflective sheet for security that is difficult to be counterfeited, cannot be reused if once released, includes a printed image that can be identified visually regardless of an object to be attached such as a colored glass and also can be identified visually clearly even in the night time, and is directed to providing a method for manufacturing the same. The retroreflective sheet for security of the present invention includes: a surface layer 1; a binder layer 2; high-refractive-index glass beads 3; a print resin layer 4; a focusing layer 5; a metal layer 6; and a pressure-sensitive adhesive layer 7 in this order, wherein the print resin layer 4 forms a mark, the high-refractive-index glass beads 3 are disposed in the binder layer 2, a position for disposing the high-refractive-index glass beads 3 does not coincide with a position of the print resin layer 4, when being observed from the surface layer 1 side in a thickness direction of the retroreflective sheet for security, and the print resin layer 4 is made of a composition containing a room temperature curing resin as a main component.

An amplitude control circuit controls the amplitude of a correction signal periodically changing in a parabolic form at vertical scanning intervals based on the level of an amplitude control signal and applies an amplitude controlled output signal to an adder. The adder adds the amplitude controlled correction signal to the output signal of a low-pass filter and applies the resulting signal to a retrace scanning control circuit and a trace scanning control circuit. The retrace scanning control circuit and the trace scanning control circuit apply a gate pulse to horizontal output FETs.

A plasma addressed liquid crystal display device has a plurality of plasma channels, each having discharge electrodes for plasma discharge, in an area divided by parallel partitions associated with reference electrodes. The discharge electrodes are formed by a pair of transparent electrodes having pre-set electrode widths and electrode intervals and a bus electrode of a material lower in the electrical resistance than the material of the transparent electrode and which is arranged in association with each transparent electrode. With the present plasma addressed liquid crystal display device, stable display can be obtained in an entire area of the viewing screen.

An error component such as an eccentricity implicated in an encoder itself is superimposed upon a detected value from an FG due to an assembly error of assemblies themselves and in the manufacturing process. As a result, a speed could not be controlled with a high accuracy and wow and flatter could not be reduced. A tape speed (TSS) signal detected and corrected from the tape transport by FG and PG is inputted into a PLL loop within a data controller (TBC) of a reproducing system. A reproduced signal is converted by an A/D converter in response to a reference clock generated therein and this data is temporarily stored in an FIFO. When this data is reconverted by a D/A converter into an analog signal, if this data is sequentially converted at a timing of an absolute control clock of a quartz oscillator, then it is possible to eliminate the error component superimposed upon the head reproduced signal. Thus, from a theory standpoint, it becomes possible to erase the wow and flatter of the drive mechanism system from the head reproduced signal.

A driving device in which when a cartridge is inserted with a correct orientation, a retainer protrusion of a drawing-in member engages a retainer recess of the cartridge, so that a sliding shaft of the drawing-in member slides along a guide surface to draw in the cartridge. When the cartridge is inserted with a reversed orientation, the drawing-in member is pushed sideways, so that the sliding shaft slides along a relief guide portion at the exterior side of the guide plate, causing the drawing-in member to be driven in the X1 direction. Since the drawing-in member is driven along the relief guide portion, locking of the mechanism does not occur. Accordingly, it is possible to prevent locking of a mechanism, which occurs when the cartridge is inserted with a wrong orientation, and the drawing-in member, which is not retained by the cartridge, is driven in the drawing-in direction, in a disk device in which a drawing-in member is used to draw in a cartridge of, for example, a mini-disk.

A method for producing a metal thin film on a substrate includes: a step of applying an ink to a flat blanket; a first transfer step of bringing the first blanket and a letterpress having a predetermined pattern of projections into contact by a pressure compression while the flat blanked and the letterpress being disposed opposite each other, to selectively transfer a portion of the ink on the flat blanket corresponding to the projections to the letterpress; a second transfer step of bringing the flat blanket obtained after the first transfer step and the substrate into contact by pressure compression while the flat blanket and the substrate being disposed opposite each other, to transfer the ink remaining on the flat blanket to the substrate; and a step of subjecting the substrate obtained after the second transfer step to electroless plating to deposit a metal thin film on the substrate.

An image heating device includes: a rotatable heater for heating an image on a recording material; a pressor for pressing the heater to form a nip in which the recording material is to be nip-conveyed; a belt for heating and contacting the heater; a first member for heating the belt while pressing the belt against the heater; a second member, provided downstream of the first member with respect to a rotational direction of the heater, for heating the belt while pressing the belt against the heater; a first portion for heating the first member by energization; and a second portion for heating the second member by energization. Each of the first and second portions is supplied with power so that a maximum of the power supplied to the first means is smaller than that of the power supplied to the second portion.
