Title: Facsimile communication system
Inventor: CHIMURA YASUBUMI
IPC: H04N1/32
Filed: 1998-05-21
Abstract: Pixel information and control information transmitted by a facsimile machine 1a is received by a procedure controlling circuit 13 having a MODEM 13a for facsimile machines.  A facsimile procedure controller 14 decodes the pixel information and the control information.  A connection/transfer controller 15 edits the decoded information and produces a control packet and a pixel packet. The control packet and the pixel packet are output to a local area network (LAN) 4 via a LAN controller 17 and a LAN control circuit 18.  When receiving a facsimile, the control packet signal transmitted via the LAN 4 is converted into pixel control information by the connection/transfer controller 15, and the pixel control information is supplied to the facsimile procedure controller 14.  The connection/transfer controller 15 also converts the received pixel packet signal into pixel information. The pixel information is temporarily stored in a memory 16.  When a predetermined amount of pixel information is accumulated in the memory 16, said predetermined amount of pixel information is supplied to the facsimile procedure controller 14, and finally transmitted to the facsimile machine 1a via the procedure control circuit 13.

Title: Motion activated illuminating footwear and light module therefor with continuous/sequential oscillating lights
Inventor: WUT SIU BUN
IPC: H05B37/02
Filed: 1998-06-29
Abstract: A light module for use with a plurality of light sources mounted to footwear, includes a power supply, an oscillator circuit, a power supply transmission circuit and a switch. The oscillation circuit supplies power to the light sources to sequentially cause illumination of the light sources. The switch has an open condition and a closed condition. A power transistor of the power supply transmission circuit has an input connected with the switch, and an output path connected between the power supply and the oscillation circuit for supplying power from the power supply to the oscillation circuit when the switch is closed and for terminating over time the supply of power from the power supply to the oscillation circuit when the switch is open. A bypass circuit includes diodes connected between the oscillation circuit and the switch to disable the oscillation circuit in order to continuously illuminate the light sources when the switch is closed. The bypass circuit is disabled when the switch is open. A first capacitive device of the power supply transmission circuit is connected between the input and the output path of the power transistor for storing a charge when the switch is closed and for discharging through the output path of the power transistor when the switch is opened to cause the oscillation circuit to sequentially supply power to the light sources and sequentially cause illumination of the light sources until the stored charge of the first capacitive device falls below a predetermined value.

Des éléments déflecteurs de flux (22), de forme allongée, sont implantés côté admission du classeur et répartis sur sa circonférence. Vu de l'extrémité d'admission (11) du classeur, chaque élément déflecteur de flux de forme allongée s'étend obliquement par rapport à l'axe central du classeur et vers l'avant par rapport au sens de rotation des lames du rotor. Selon l'invention, la distance entre les éléments déflecteurs de flux (22) adjacents, sur la circonférence du classeur, est inférieure à 6 mm. On obtient ainsi une grande efficacité en termes de séparation des particules indésirables sans pour autant altérer la capacité.
