Title: Back light dimming method of lcd display
Inventor: HONMA YASUHIDE
IPC: H05B41/392
Filed: 1992-09-03
Abstract: PURPOSE:To improve quality of a picture. CONSTITUTION:A detection output from an I-V converter 11 is compared with a set output from a volume control 4, and an output of a DC-DC converter 7 is controlled so that the current running in a cold cathode electric discharge tube 8 is set to a value determined by the volume control 4. The output of the DC-DC converter 7 is controlled by feedback control based on the detection output from the I-V converter 11. Generation of power source noise can be prevented by changing the output variation in the DC-DC converter 7, unlike in a PWM method. Since the output of the DC-DC converter 7 is controlled by the feedback control based on the detection output from the I-V converter 11, stable dimming control is carried out constantly without being affected by the variation in the impedance characteristic of each circuit element due to the change in the environmental temperature, and the quality of the picture is thus improved.

Title: Still picture receiver
Inventor: KIMURA NORIO
IPC: H04N7/081
Filed: 1987-10-16
Abstract: PURPOSE:To attain easy to see monitor screen by providing an erasure means inhibiting the supply of a still picture stored in a storage means onto a monitor and preventing mixture display of a picture sent newly and an existing storage picture on the monitor pattern. CONSTITUTION:Picture information inputted from an input terminal 1 is stored in a picture memory 4 via an input I/F 2 or the like. When a central arithmetic processing unit 9 discriminates the data reception from the sender side at the reception, the data erasure of the memory 4 is commanded to the erasure circuit 8. The circuit 8 erases the data in the memory 4 via a memory controller 5 before the unit 9 writes the reception data inputted from a modulator- demodulator 10 in the memory 4. Then the unit 9 stores the received picture data into the memory 4 via the controller 5 in the order of R, G, B sequentially. On the other hand, the picture data stored in the memory 4 is displayed on the monitor 7 via a D/A converter 6 by the controller 5. Thus, the mixed display of the existing storage picture and the new input picture on the monitor screen is prevented to attain ease to view monitor screen.

Title: Duplicating machine
Inventor: NISHIYAMA MASATAKA
IPC: B41M5/28
Filed: 1991-09-12
Abstract: PURPOSE:To simplify the constitution of a duplicating machine by shaping a recording sheet in which an image such as character can be printed on the part irradiated with a light of specific wavelength, in the interior of the machine and emitting a light reflected from a copy directly to the recording sheet. CONSTITUTION:Base sheets 11 are taken out one by one from a sheet feeder tray 34 using a sheet feed roller 35, then a toner-like blend is uniformly applied to the entire upper surface of the base sheet 11 and is fixed using a heater 52. The speed of a recording sheet 10 which travels at the bottom of a transparent glass 33b by a recording sheet feed mechanism 33 is synchronized with the copy scanning speed of a scanning mechanism 22. If an image is formed by emission of a reflecting light from a copy O on the recording sheet 10 through a focusing lens system 30 and a fixed mirror 31, a discoloration layer where the reflecting light hits of the recording sheet 10 becomes transparent resulting in the change of a color in the base sheet 11 and the subsequent recording of data. Thus a photosensitive medium for transfer and a development device are no longer required for a duplicating machine and the duplicating machine becomes simple structurally.
